Spanish Verbs Followed by De and an Infinitive
Spanish Verbs Followed by De and an Infinitive One common way of connecting verbs in Spanish that has no full equivalent in English is to follow the verb with the preposition de and an infinitive. A simple example would be a sentence such as Dejaron de fumar, where a conjugated form of the verb dejar (here meaning to give up or to quit) is followed by de and the infinitive fumar (meaning to smoke). This sentence would typically be translated as They quit smoking; although the infinitive after de is translated to English as a gerund, that isnt true in all cases where a verb and de are followed by an infinitive. Note that with most of these verbs, de isnt translated as of or from but gains its meaning as part of a unit with the verb. Commonly Used Verbs Followed by De Following are some of the verbs most commonly followed by de and an infinitive, along with examples of their usage. Note that many of the verbs have to do with ending an action. acabar de (to finish, usually recently): Acabo de leer la biografà a de Simà ³n Bolà var. (I just read Simon Bolivars biography.)debo de (to have to, to be obligated to):  ¿Quà © medicamentos debo de tomar? (What medications do I have to take?)dejar de (to quit, to abandon): Mi esposa quiere dejar de trabajar para cuidar a nuestro bebà ©. (My wife wants to quit working in order to take care of our baby.)depender de (to depend on): El futuro de nuestra sociedad depende de ganar la lucha al crimen organizado.

(I have quit believing in humanity.)tratar de (to try to): Trata de ser feliz con lo que tienes. (Try to be happy with what you have.) Reflexive Verbs Followed by De Many of the reflexive verbs followed by de and an infinitive involve mental processes and/or actions based on emotions: acordarse de (to remember): No me acuerdo de ver a nadie sacando fotos. (I dont remember seeing anyone taking pictures.)alegrarse de (to be happy to): Se alegra de haber realizado el cambio y afirma que eso era la carrera que estaba buscando.

Understanding French Stressed Pronouns
Understanding French Stressed Pronouns Stressed pronouns, also known as disjunctive pronouns, are used to emphasize a noun or pronoun that refers to a person. There are nine forms in French. Please see the table at the bottom of the page. French stressed pronouns correspond in some ways to their English counterparts, but are very different in other ways. Note that the English translations sometimes require different sentence structures altogether. Stressed pronouns are used in the following ways in French: I. To emphasize nouns or pronouns (accent tonique)    - Je pense quil a raison.    - Moi, je pense quil a tort.    - Je ne sais pas, moi.    - I think hes right.    - I think hes wrong.    - I dont know. II. After cest and ce sont (accent tonique)    Cest toi qui à ©tudies lart.    Youre the one whos studying art.    Ce sont elles qui aiment Paris.    They love Paris. III. When a sentence has more than one subject or object   Michel et moi jouons au tennis.    Michael and I are playing tennis.   Toi et lui, vous à ªtes trà ¨s gentils.    You and he are very kind.   Je les ai vus, lui et elle.    I saw him and her. IV. To ask and answer questions    - Qui va la plage ?    - Lui.    - Who is going to the beach?    - He is.    Jai faim, et toi?    Im hungry, and you? V. After prepositions    Vas-tu manger sans moi?    Are you going to eat without me?    Louis habite chez elle.    Louis lives at her house. VI. After que in comparisons    Elle est plus grande que toi.    She is taller than you (are).    Il travaille plus que moi.    He works more than I (do). VII. With emphatic words like aussi, non plus, seul, and surtout    Lui seul a travaillà © hier.    He alone worked yesterday.    Eux aussi veulent venir.    They want to come too. VIII. With -mà ªme(s) for emphasis   Prà ©pare-t-il le dà ®ner lui-mà ªme?    Is he making dinner himself?   Nous le ferons nous-mà ªmes.    Well do it ourselves. IX. With the negative adverb ne...que and conjunction ne...ni...ni   Je ne connais que lui ici.    Hes the only one I know here.    Ni toi ni moi ne le comprenons.    Neither you nor I understand it. X. After the preposition to indicate possession   Ce stylo est moi.    This pen is mine.   Quel livre est toi?    Which book is yours? XI. With certain verbs that dont allow a preceding indirect object pronoun   Je pense toi.    Im thinking of you.    Fais attention eux.    Pay attention to them. Note: Soi is used for unspecified persons. Would you like to test your skills with French stressed pronouns? English French me moi you toi him lui her elle oneself soi us nous you vous them (masc) eux them (fem) elles How to Use the French Pronoun Soi Soi is one of the most often misused French pronouns. Its the third person indefinite stressed pronoun, which means that it is used only for unspecified persons; i.e., with an indefinite pronoun or impersonal verb. Soi is equivalent to one or oneself, but in English, we usually say everyone instead.    On va chez soi.   Everyone is going (to his or her respective) home.    Chacun pour soi.   Every man for himself.    Il faut avoir confiance en soi.   One should have confidence in oneself (in him/herself).    Tout le monde doit le faire soi-mà ªme.   Everyone has to do it him/herself. Some French students get confused between soi-mà ªme and lui-mà ªme. If you remember that soi can only be used for unspecified persons, you should be ok.   Il va le faire lui-mà ªme.   Hes going to do it himself.   On va le faire soi-mà ªme.   Everyone is going to do it him/herself.

Questions asked, Explain below questions - Essay Example The situation of the economy, such as economic booms and economic meltdown is a key competitive factor in global Smartphone industry. Economic meltdown will reduce the disposable income of customers. At that point of time companies are going for less costly smart phones. If the economy is booming customer’s disposable income would increase and companies starts to compete on high-end smart phones. Reliability of the brand and user friendliness of the smart phones is also a very key competitive factor affecting the company seriously. Before buying any smart phones customers search for different attribute and features like applications, internet speed, picture qualities etc (James, Laurence and Changhoon, 2011, PP. 343-353).

German - Assignment Example oon during daytime and will tie a rope in the oak tree and pull the moon down and when it lays on the ground, they will cover it with cloth so no one will notice the robbery. 6. Once back home, what do they do with the moon, and how do the people and dwarfs react? Once the travelers got home, they happily placed the moon up the oak tree and the people were glad the entire field as well as all of the chambers were filled with brightness, while the dwarfs came out and danced with joy. 7. When one of the travelers is getting sick and facing death, what does he order? When one of the travelers fell ill and foresaw his death, he requested that the fourth part or a quarter of the moon should be given to him and be laid upon his coffin. 9. Describe what the dead do when they wake up. When parts of the moon re-united in the underworld, the 4 travelers rose from their grave and became astonished when they knew that they could still see. They became amusing and accepted of the magistrate’s old life-style again. And eventually, they play, dance, get drunk until they finally quarreled to each and everyone. 10. Why do the dead prefer the moon to the sun? The dead prefer the moon because this is the only thing that they do not have in their previous land and that they could take parts of the moon to themselves. Once, there was a land that lived in complete darkness – no moon has ever appeared in it but only stars. When the sun set behind mountains, there comes a luminous ball stood high up an oak tree and generously poured out light to the entire land. Hence, the luminous ball in the oak tree served as a moon for the people who lived there. One night, four travelers who have came from another country planned to steal the luminous ball so they could bring it to their magistrate and her land that does not have a moon. They asked a farmer what that luminous ball stand for and later found out that it was their â€Å"moon†and could only give light or brilliance by pouring

First flight Essay Example for Free
First flight Essay First flight The warm wind blows past me. Only two colours can be seen in all directions. The bright blue of the mid day sky and the bronze, bare earth carrying on for miles. Across the endless plains are plants speckled by plants that look more like scattered ants from here. I close my eyes and face the sun. Burning rays hit my face. I stand on the edge of a canyon, my bare feet burning on the hot desert sand. My toes curled over the edge. I imagine what may lie at the bottom of this seemingly endless fall. I think of a rushing river ripping at the walls, making the canyon deeper and deeper. I imagine myself falling through the air straight to the bottom of the canyon. I know if I dont do this now I will be stuck to walk this planet like every other being. I tilt my body forward, I start to lose my balance, my heart is racing, and with one last gulp of air and my eyes closed I dive forward. I feel the air separating as I cut through it. My body spinning as I fall. I open my eyes and watch the sides of the gorge rushing past me. It feels nice, no wonderful, superb, and magnificent, as if time has stood still. Faster, faster. I rush towards the end. The end of being trapped, without freedom to do what you want, go where you please. I close my eyes again and enjoy this amazing feeling. Voices mumble in the background. They grow louder as I drift back into reality, turning into shouts. I snap open my eyes. The bottom is very close, a tiny stream trickles through the giant crack in the earth, nothing like I imagined before. Is there anything I can do now? I try to remember what Im supposed to do. Before I could recite her lessons word for word but now when I need them most, my head is only filled with her face. The bottom is so close now I can see the ripples in the water; I can make out the colours of the stones underneath the clear running water. My heart is racing faster than ever before, I want to scream but nothing comes out. I pull my head up and the spinning stops. I realise Im dizzy and everything is swaying back and forth. I pull my wings out just in time and I glide above the tiny stream. The bottom, which was once so far away, my claws dangle just above. I flap my wings, pull my legs in and start to make my way back up to the top. My dizziness fades and I notice as I make my way back to the top, the plants clinging to the side of the beaten walls. When I reach the top I see the terrified look on my mothers face which she is trying to cover up with a smile. I plant my feet on the hot desert sand. I look at her and she shakes her head. I turn to my brothers talking about how amazing I was. Mum turns and they follow her talking about how it will be one of their turns tomorrow. I turn back to the edge of the canyon and face the sky with my eyes close. Ive done it. My first flight.

Modern Changes in International Equity Markets Essay -- essays papers
Modern Changes in International Equity Markets Few things, you might think, are as enduring as a national stock exchange. From pillared entrance to pulsating floor, they display an institutional solidarity that can surely defy forces for change. And yet most of the world’s bourses are now in turmoil, as they scrabble to be seen making alliances or mergers, to fend off electronic competitors, or simply to survive. Even New York, the biggest of the lot, is worried: while London, the biggest in Europe, seems to lurch from one misstep to another. (The Economist, 17th June 2000). These missteps have come about from a number of structural changes that have, and are still occurring within national, and global economic environments. A major change is with mergers of many equity and derivative markets, Switzerland 1993, Germany 1994, Netherlands, Finland, France and Austria in 1997. (Bank Of England, 1999). This and other changes such as cross member ship agreements and new parallel links between exchanges, have, and still ar e creating and manipulating the international markets. The essay will then explain why these changes have occurred, looking in depth at technology advances, technology and scale of economies, technology and competition, cross border investment, globalisation and new role taken by finical intermediaries, providing specific examples of these changes seen with current examples. The essay will conclude with a brief summary of what the larger markets are doing to combat this changes. There have been two major structural changes in markets over the past decades. The first of which is the mergers between equity and derivative exchanges within countries and secondly the new types of links, created by technological advances between exchanges.

The Effects of Cramming for an Examination
The effects of cramming for an examination You are a student, have you ever heard someone to complain: â€Å"oh my god, I have only one day to review for the final test? †In the fact, they knew schedule exams from a month ago, but, they don’t care it until the last day before an exam. The real only solution is to cram. Some students even seem to prefer it because it challenges them and give them more time to go out with your friends on the weekend.In contrast, cramming has many bad effects as: exhaustion, knowledge overload and bad result. Firstly, cramming is a reason make you exhausted. By cramming, you’re trying to learn everything you can in the limited time you have to study. So, to do that you must awake through at night to learn, after you could be sleep deprivation. Thus, it can make you feel asleep, tired and loss of appetite in the day after. Cramming can leave you feeling down and worn out in the end.Secondly, cramming make us knowledge overload. Many students believed in the last day, before do the test they can learn by heart all knowledge. However, the brain is a sponge, but just like any sponge oversaturated very fast. A brain filled to the brim with knowledge will seep out the knowledge instead of retaining it. Therefore, you should add this information more slowly, over time; you may find yourself more capable of absorbing a larger knowledge. Thirdly, a big consequence of cramming is bad result.Sleep deprivation can cause poor memory, lack of alertness and overload knowledge, often leading to lower test grades. However, when you study for an examination with an intense cram session, at first you might assume that you will pass. But, the low mark will come as a surprise to you and your grade point average. If you do not study for a test, you probably will expect that you are going to fail or at least not do so well. Remember that: â€Å"Cramming is not the best way to get the score you seek†.Conclusion, though crammi ng has been a studying practice for generations; it is actually a bad method to review and many negative effects. These include: exhaustion, overload knowledge and bad result. Because above all that reasons, before waiting until the last minute to study for your next big exam, you should study hard at this moment and think about its consequences. Moreover, don’t waste your time to do useless things but you must manage time better in the future to improve themselves not only in school, but also in your life. /.

To what extent was the treaty of Versailles
To what extent was the treaty of Versailles motivated by anti-German feeling? sy Rewaj123 Without doubt it is clear that some of the countries held great antiGerman feelings during and after the war. Especially France, they held the highest lack of remorse against the Germans. Whereas countries such as the United Kingdom and the USA wanted majority peace throughout Europe and felt that peace was the main objective rather than annexation of land etc.It is fundamentally clear that Frances ideas ursued in the treaty was solely based on anti German feelings, They wanted to annex the Rhineland and, even worse, the coal production would be given to France with reparations On top Of that. 3y taking their coal supply Germany will crumble. They already Owe money from the war originally and With no money coming in, due to the coal annexation, the country Will have little income'industry.Consequently Germany Will not be able to deal With all these problems and cease to exist as a countr',q With France this is ultimately about the anti-German feelings seeing as hough Germany tried major annexation of land and a takeover of France, the feelings are completely understandable. Also one could argue that (article 231) the war guilt clause was also triggered by anti-German feelings. They knew that the clause would cause extreme unrest In Germany and due to the blame Germany would have this would seriously affect the country as a whole, In the long-term.Britain developed a growing sympathy tor Germany whereas France thought It was being too lenient. However It was also the situation created by the war that shaped the term of the treaty and not just anti-German feeling. It should be mentioned that it wasnt Just Germany but Austria-Hungary and Turkey also had to sign treaties, which shows It Isnt solely about antiGerman feelings. Plus the treaty has to sufficiently appease the other countries so German consequences were also inevitable. Personally I think that the French ideas were motivated with antiGerman feelings but the other countries wanted what was best for theirs.

Fredrick Douglass1 essays
Fredrick Douglass1 essays The brutality that slaves endured form their masters and from the institution of slavery caused slaves to be denied their god given rights. In the Narrative of the Life of Frederick Douglass, Douglass has the ability to show the psychological battle between the white slave holders and their black slaves, which is shown by Douglass own intellectual struggles against his white slave holders. I will focus my attention on how education allowed Douglass to understand how slavery was wrong, and how the Americans saw the blacks as not equal, and only suitable for slave work. I will also contrast how Douglass view was very similar to that of the women in antebellum America, and the role that Christianity played in his life as a slave and then as a free man. The novel clearly displays the childrens animalistic behavior when they were not regularly allowanced. Douglass says, Our food was coarse corn meal boiled, which was called mush. It was put into a large wooden tray or trough, and set down upon the ground. The children were then called, like so many pigs, and like so many pigs they would come and devour the mush; some with oyster-shells, others with pieces of shingle, some with naked hands, and none with spoons. He that ate fastest got most; he that was strongest secured the best place; and few left the trough satisfied" (Douglass 41-42). This clearly describes how children where treated like animals and their inability to act in the manner of a normal educated child. Slave children were denied many luxuries that other children took for granted. The knowledge of their birthdays was one of these luxuries. Douglass states, "I have no accurate knowledge of my age, never having seen any authentic record containing it. By far the larg er part of the slaves know as little of their ages as horses know of theirs, and it is the wish of most masters within my knowledge to keep their slaves thus ignorant. I ...

Greenland Shark Facts (Somniosus microcephalus)
Greenland Shark Facts (Somniosus microcephalus) The cold waters of the North Atlantic and Arctic Ocean are home to the worlds longest-lived vertebrate: the Greenland shark (Somniosus microcephalus). The large shark goes by several other names, including gurry shark, grey shark, and eqalussuaq, its Kalaallisut name. The Greenland shark is best known for its impressive 300 to 500 year life span, as well as its use for its use in the Icelandic national dish: kà ¦stur hkarl. Fast Facts: Greenland Shark Scientific Name: Somniosus microcephalusOther Names: Gurry shark, grey shark, eqalussuaqDistinguishing Features: Large gray or brown shark with small eyes, rounded snout, and small dorsal and pectoral finsAverage Size: 6.4 m (21 ft)Diet: CarnivorousLifespan: 300 to 500 yearsHabitat: North Atlantic and Arctic OceanConservation Status: Near ThreatenedKingdom: AnimaliaPhylum: ChordataClass: ChondrichthyesOrder: SqualiformesFamily: SomniosidaeFun Fact: Chef Anthony Bourdain said kà ¦stur hkarl was the single worst, most disgusting and terrible tasting thing he ever ate. Description Greenland sharks are large fish, comparable in size to great whites and in appearance to sleeper sharks. On average, adult Greenland sharks are 6.4 m (21 ft) long and weigh 1000 kg (2200 lb), but some specimens reach 7.3 m (24 ft) and 1400 kg (3100 lb). The fish are gray to brown in color, sometimes with dark streaks or white spots. Males are smaller than females. The shark has a thick body, with a short, round snout, small gill openings and fins, and small eyes. Its upper teeth are thin and pointed, while its lower teeth are broad with cusps. The shark rolls its jaw to cut away pieces of its prey. Greenland shark (Somniosus microcephalus). NOAA Okeanos Explorer Program Distribution and Habitat The Greenland shark is usually found in the North Atlantic Ocean and Arctic Ocean between sea level and a depth of 1200 m (3900 ft). However, the fish migrate to deeper water further south during the summer. One specimen was observed off the coast of Cape Hatteras, North Carolina at 2200 m (7200 ft), while another was documented at 1749 m (5738 ft) in the Gulf of Mexico. Greenland shark distribution. Chris_huh Diet The Greenland shark is an apex predator that feeds mainly on fish. However, it has never actually been observed hunting. Reports of scavenging are common. The shark supplements its diet with reindeer, moose, horse, polar bears, and seals. Adaptations While the shark feeds on seals, researchers are unclear how it hunts them. Because it lives in frigid water, a Greenland shark has an extremely low metabolic rate. In fact, its metabolic rate is so low that the species has the lowest swimming speed for its size of any fish, so it cannot swim fast enough to catch seals. Scientists hypothesize sharks may catch seals while they are sleeping. The low metabolic rate also leads to the animals slow growth rate and incredible longevity. Because sharks have cartilaginous skeletons rather than bones, dating their age requires a special technique. In a 2016 study, scientists performed radiocarbon dating on the crystals in the lenses of eyes of sharks caught as bycatch. The oldest animal in that study was estimated to be 392 years of age, plus or minus 120 years. From this data, it appears Greenland sharks live at least 300 to 500 years, making them the worlds longest-lived vertebrate. The biochemistry of the Greenland shark is adapted to allow the fish to survive extremely cold temperatures and high pressures. The sharks blood contains three types of hemoglobin, allowing the fish to obtain oxygen over a range of pressures. The shark is said to smell like urine, due to the high levels of urea and trimethylamine N-oxide (TMAO) in their tissue. These nitrogenous compounds are waste products, but the shark uses them to increase buoyancy and maintain homeostasis. Most Greenland sharks are blind, but not because their eyes are small. Rather, the eyes are colonized by copepods, occluding the fishs vision. Its possible the shark and copepods may have a mutualistic relationship, with the crustaceans displaying bioluminescence that attracts prey for the shark to eat. Reproduction Very little is known about Greenland shark reproduction. The female is ovoviviparous, giving birth to about 10 pups per litter. The newborn pups measure 38 to 42 cm (15 to 17 in) in length. Based on the animals slow growth rate, scientists estimate it takes about 150 years for a shark to reach sexual maturity. Greenland Sharks and Humans The high concentration of TMAO in Greenland shark flesh makes its meat toxic. The TMAO is metabolized into trimethylamine, causing potentially dangerous intoxication. However, the sharks meat is considered a delicacy in Iceland. The meat is detoxified by drying, repeated boiling, or fermenting. Hkarl hanging to dry in Iceland. Chris 73 Although a Greenland shark could easily kill and eat a human, there are no verified cases of predation. Presumably, this is because the shark lives in extremely cold water, so the chance of interaction with humans is very low. Conservation Status The Greenland shark is listed as near threatened on the IUCN Red List. Its population trend and the number of surviving adults is unknown. Presently, the species is caught as bycatch and intentionally for Arctic specialty food. In the past, Greenland sharks were heavily fished for their liver oil and were killed because fisheries thought they posed a threat to other fish. Because the animals grow and reproduce so slowly, they have not had time to recover. The shark is also threatened by overfishing and climate change.
