If the color turned a Burnt orange then we can conclude that the unknown solution does in fact contain glucose. ...

Definition and Examples of Cataphora in English Grammar

Definition and Examples of Cataphora in English Grammar In English grammar, cataphora is the use of a pronoun or other linguistic unit to refer ahead to another word in a sentence (i.e., the referent). Adjective: cataphoric. Also known as  anticipatory anaphora, forward anaphora, cataphoric reference, or forward reference. Cataphora and anaphora are  the two main types of  endophorathat is, reference to an item within the text itself. Cataphora in English Grammar The word that gets its meaning from a subsequent word or phrase is called a cataphor. The subsequent word or phrase is called the antecedent, referent, or head. Anaphora vs. Cataphora Some linguists use anaphora as a generic term for both forward and backward reference. The term forward(s) anaphora is equivalent to cataphora.   Examples and Uses of Cataphora In the following examples, cataphors are in italics and their referents are in bold. Why do we envy him, the bankrupt man? (John Updike, Hugging the Shore, 1984)A few weeks before he died, my father gave me an old cigar box filled with faded letters.In The Pendulum Years, his history of the 1960s, Bernard Levin writes of the collective insanity which seized Britain. (The London Evening Standard, February 8, 1994, quoted by Katie Wales in Personal Pronouns in Present-Day English. Cambridge University Press, 1996)If she were alive today, [Barbara] Tuchman would surely be preparing to pen fresh furious pages tonight, as the president seeks to rally his faltering domestic popularity with summonses of support. (Martin Kettle, If He Resists the Siren Voice of Folly, Blairs Legacy Is Secure. The Guardian, June 25, 2005)You must remember this:A kiss is just a kiss,A sigh is just a sigh. (Herman Hupfeld, As Time Goes By, 1931)This, I now realize, was a very bad ideasuggesting we do whatever Terry Crews wants for the day. (Joel Stein, Crews Control. Time, September 22, 2014) It must have been tough on your mother, not having any children. (Ginger Rogers in 42nd Street, 1933)Too scared to buy before they sell, some homeowners aim for a trade.So I just want to say this to the Congress: An America that buys much more than they sell year in and year out is an America that is facing economic and military disaster. (Congressman James A. Traficant, Congressional RecordHouse, September 25, 1998)After she declared herself broken, betrayed, at bay, really low in another organ yesterday, Im not sure the Diary should even mention poor Bel Mooneys name. (The Guardian, August 9, 1994) Creating Suspense With Cataphora [Cataphora] is in evidence in the next example, which is typical of the opening sentences of books: Students (not unlike yourselves) compelled to buy paperback copies of his novelsnotably the first, Travel Light, though there has lately been some academic interest in his more surreal and existential and perhaps even anarchist second novel, Brother Pigor encountering some essay from When the Saints in a shiny heavy anthology of mid-century literature costing $12.50, imagine that Henry Bech, like thousands less famous than he, is rich. He is not.​[John Updike, Rich in Russia. Bech: A Book, 1970] Here we meet copies of his novels before we know who he is. It is only several lines later that the possessive adjective his links forward to the proper nouns Henry Bech in the text that comes after. As you can see, whereas anaphora refers back, cataphora refers forward. Here, it is a stylistic choice, to keep the reader in suspense as to who is being talked about. More usually, the noun that the pronoun links forward to follows soon after. (Joan Cutting, Pragmatics and Discourse: A Resource Book for Students. Routledge, 2002)Strategic Use of Cataphora [M]ore often than not, protypical cataphora is motivated by a planned or strategic delivery of a referent, such as in news-telling like the following: Listen to thisJohn won a lottery and got a million dollars! Prototypical cataphora thus is rarely associated with problems in lexical retrieval. (Makoto Hayashi and Kyung-Eun Yoon, Demonstratives in Interaction. Fillers, Pauses and Placeholders, ed. by Nino Amiridze, Boyd H. Davis, and Margaret Maclagan. John Benjamins, 2010) Cataphora and Style [S]ome prescriptive grammarians have gone so far as to condemn the practice [of cataphora], for reasons of clarity and, more blandly, good style. So H.W. Fowler declares the pronoun should rarely precede its principal, a view echoed by Gowers . . .. This has led to problems in terminology. The term antecedent, for example, is commonly used to refer to a coreferential NP in an anaphoric relation; there is no equivalent expression for the *postcedent NP, however. But by an odd semantic license, some grammarians, and of different schools of thought, use antecedent in this sense. (Katie Wales, Personal Pronouns in Present-Day English. Cambridge University Press, 1996) EtymologyFrom the Greek, backward carry Pronunciation: ke-TAF-eh-ra

Blog - Article Example This is symbolically a romantic experience and as seen it builds up the imaginations which follow. In most of the modern Hollywood films, the same is the case. Women are elements of romance and they motivate all what men do. This is clearer from the latest Vampire Diary series where everything happens motivated by romance around Elena Gilbert. There exists some difference between the old films and the new. You will realize that, the old films presumed the natural gender roles and women were only viewed as subservient persons there for a man’s pleasure and taking care of the family. In â€Å"Octavian Saint Laurent from Paris is Burning Documentary†, she believes in the provocative ideologies as a means to reach men’s hearts. This is not the case in the modern movies where the women are depicted to be very dynamic characters who believe that whatever a man can do, a woman can threefold or more and do it in a match better way. Look at a modern movie of â€Å"Mr. and Mrs. Smith†. Both are detectives and they do their jobs equally well. The woman presented here is of independent character. Earlier in times, women were very uncommon in arts and films. They were literary ignored and this something which they did not like. However, despite the fact that there were women who were artist in old days, their efforts were also trivialized and this why history has a few number of great women artists. This concern prompted Linda Nochlin to write an essay that brought a revolution in the art and film industry as far as women are concerned. She asked the big question as to why there are no female artists in history and then people began to think (Druckman 26). One of the impacts of her work is that it led to artistic liberation of all women who were interested into joining the arts and film industries. A feminist arts movement was established to champion for the rights of women in

Persuasive Research Paper on ( Gun Control) Example | Topics and Well Written Essays - 750 words

Persuasive on ( Gun Control) - Research Paper Example There were 280 million firearms in private hands in America in 2005 and there were only 300,000 gun crimes (Kessler 46). For Kessler, this means that at least 279,700,000 guns did nothing wrong (46). Further, Kessler added that in 89% of the crimes, the person who used the gun was not the one who bought the gun (46). Kessler interpreted the data to mean that the root of America’s crime problem is not the number of guns in the hands of American (46). Kessler’s key argument is that American should not restrict gun rights but should â€Å"deepen† instead the sense of gun ownership (47). In a way, Jim Kessler hit the nail on the head. Indeed, deepening the sense of gun ownership will probably decrease the crime rate. However, this sense of ownership can be deepened not through liberal gun laws but by regulating people’s access to guns. This should not be interpreted as curtailment of rights. In the same way that the right to free speech is moderated by libel laws, the rights to gun ownership will have to be moderated by society’s consideration for the general good. This is because not all persons are ready enough to own guns. Not all individuals are responsible enough to have unhampered access to guns. Responsible gun ownership is promoted best not through liberal gun laws but through gun control. In 1993, Professor Martin Killias of University of Lausanne, Switzerland, examined the correlations between household gun ownership and rates of homicides and suicides using a gun in eleven European countries, Australia, Canada and the United States (Killias 1721). Killias found that there is a positive correlation between gun ownership and the rates of homicides and suicides using a gun in the fourteen countries (1721). In citing examples, Killias pointed out that the United States homicide was 3.7 times higher than Britain and the US suicide with a handgun was 175 to 1 compared with the US (1722). He

The Criminal Is Not Solely Responsible for His Crime Essay -- Exposito

Clarence Darrow in his "Address Delivered to the Prisoners in the Chicago County Jail," presents a convincing argument for the complicity of society with the criminal. In essence, Darrow believes that when one man steals from another, the community is as culpable as the criminal, since no man who "already had plenty of money in his own pocket" (82) would risk his life and liberty to rob or steal from another. According to Darrow, the root of the problem lies in poverty and the hoarding of wealth by a handful of people who become rich by exploiting the poor through cheap labor, or by appealing to their vices. It is interesting to note that during hard times crime increases. Particularly, periods of high inflation, or unusually cold winters. That’s when people cannot afford to pay high heating bills. Faced with no choices and an adverse situation, criminals literally "break into jail" (82) because it is better than being on the outside. Case in point: homeless people. I saw a homeless man in downtown LA, with a hospital band on his arm, deliberately provoke a security guard into calling the police. After the police arrived, the homeless man calmed down and quietly entered the squad car, cordially waving at the security guard. It was a cold rainy day. Clearly the homeless guy found L. A. County Jail preferable to the streets. Another example involves habitual criminals who become "institutionalized." This point was poignantly dramatized in the movie "Shawshank Redemption." The character played by Morgan Freeman contemplated suicide after release from prison because he had been institutionalized for so long that he no longer had coping skills for the outside world. That is, until offered a real "chance to live" (83) by his fello... ...would understand justice, how shall you unless you look upon all deeds in the fullness of light? Only then shall you know that the erect and the fallen are but one man standing in twilight between the night of his pigmy-self and the day of his god-self. And that the corner-stone of the temple is not higher than the lowest stone in its foundation" (46-47). The criminal is not solely responsible for his crime. There is much truth in the maxim "No man is an island. No man stands alone. Each man is my brother. Each man is my friend."

Women in Mythology

In myths the classical hero is consistently male, but in underworld myths females tend to have a larger or primary role. Jung emphasized the importance of the women the hero encountered during his adventures: they represent the anima, or the female part of the male psyche. This figure is an opposite-sex archetype essential to the development of a complete and mature personality. Women in underworld myths are often portrayed as either â€Å"Mother Atonement†, a goddess or a temptress (189), although these are the main roles of women in underworld myths there are also women who portray a heroic role closer to that of a man.The first myth is the story of Psyche; Psyche loses her husband Cupid and must perform a series of tasks to win him back. The role of Psyche is similar to that of a male role in a traditional heroic archetype because she must complete a series of tasks in order to test her, and show her worthiness to Cupid. It is different because this myth does not contain ea ch part of separation and departure, trials and victories or return.This story includes â€Å"the call to adventure†, which is when Psyche loses cupid, â€Å"the road of trials† where Psyche must complete her many tasks and â€Å"crossing the return threshold† where she wins Cupid’s love back. The role of the woman, Psyche, in this myth and in general is significant because she plays not as much of a hero role but has to endure the process that a hero would take, she also plays neither a seductress nor a Mother Atonement role in comparison to other mythological women such as the Lady of Tubber Tintye or the virgin goddess Diana.The second myth is The Prince of the Lonesome Isle. All of the women, minus one, in this particular myth play the roles of temptresses. The first thirteen women the hero comes across are the most beautiful women he has ever laid eyes on, each more beautiful than the previous, each continuously tempting the prince to stay but he lea ves them nonetheless. The last woman in the myth, the Lady of Tubber Tintye, plays the role of a creator goddess who nourishes and protects the world(189), he stays with her six days and six nights but still continues and completes his quest (Jeremiah Curtin 101-106).The ways in which the roles of the women differ from the male roles in the traditional heroic archetype are that the women do not present a heroic archetype but rather that of a distraction from the princes original quest he wishes to complete. â€Å"In the morning they came to a house on the roadside; and going in, they saw a woman who had washed herself in a golden basin which stood before her. She was then wetting her head with the water in the basin, and combing her hair with a golden comb. She threw back her hair, and looking at the prince, said: † You are welcome, sister's son.What is on you? Is it the misfortune of the world that has brought you here? † â€Å"It is not; I am going to Tubber Tintye f or three bottles of water. † â€Å"That is what you'll never do; no man can cross the fiery river or go through the enchantments around Tubber Tintye. Stay here with me, and I'll give you all I have. † â€Å"No, I cannot stay, I must go on. â€Å"† (Jeremiah Curtin) These women are significant to the actual story because they show how the prince resisted the calls of the seductresses, met and united with a goddess who helped him to fulfill his quest.These women in the myth are significant to the portrayal of women in myths in general because they fit the stereotype of women in underworld myths being evil temptresses. But it also breaks the mold seeing as once the prince meets with the creator goddess, â€Å"queen goddess of the world†(189) she helps him to fulfill his quest rather than hindering his quest or inhibiting his ability, such as in the myth of Actaeon and the virgin goddess Diana. In the last myth, the myth of Actaeon and the virgin goddess Dia na (Artemis), Actaeon stumbles across Diana while he is hunting and happens to see her while she is bathing in a stream.Diana fears that he will brag about seeing her, and turns him into a stag, which then his own hunting dogs are set on him (189). Diana’s importance to the story shows the power that women have, they are not just pretty faces there is always something more to them. To the general portrayal of women in myths Diana unmasks the Greek male's fear of women – female beauty is not just there for his enjoyment – it has a power to trap and then destroy (Andrew Wilson) Diana’s roll differs from the traditional male heroic archetype because she is an object of lust turned somewhat evil rather than brave or heroic.She is similar to that of the heroic archetype of a male because she is a â€Å"vengeful destroyer† (Storybuilder User's Manual) towards Actaeon. In conclusion, throughout underworld mythology the role of women can stray from the typ ical â€Å"temptress or goddess† and find their way to being a woman called to an adventure. They all have significance to be able to change mythology from a man only perspective, into one where a woman can also be the hero.Although most of the women in these myths are have more differences from the male heroic archetype than similarities, they still have some form of the heroic archetype to them: Psyche’s love for Cupid is tested through tasks, and Diana uses her vengeful destroyer attitude. The women of underworld mythology show that women are not just their beauty or for looking at, they have an underlying root of skill that should allow them their own heroic archetype as well.

Most Important Thing in Travelling Essay

Most Important Thing in Travelling Travelling is the kind of activity, which almost all the people love. For someone it is an opportunity to relax and abstract from everyday busy life. For others it is interesting to observe the way people of other cultures and mentality live. Some people consider it to be the best way to have fun and always try to visit as many clubs, pubs, restaurants and cafes as possible for their wallets and time limits. Of course, there are people who are always unhappy with the way the life is, and they will say that travelling is far from pleasant and involves a lot of stress due to the necessity to pack their things, use public transport and so on. But fortunately, those people are rather few and the majority understands how travelling is exciting and interesting. As for me, I have always enjoyed watching all-round views from some altitudes. I enjoy watching them in my hometown and as soon as I am in some new city, I start looking for such spots right away. When I am in such a place, I just hold my breath and observe the beauty. At such moments I think about how our life is excellent, what beauty it offers us and how important it is to value each moment of our lives. From such places it is so exciting to observe city views and imagine how thousands of people live in there and experience so many different feelings. I understand that I am not alone, that I have so many chances and that I can reach all my goals. The views of nature are also exciting, as while watching them, I wonder how such beauty can be created and how it is important not to spoil it. To sum up, travelling is great due to the fact that each and every person can find something interesting and exciting for him- or herself. The main thing here is to be open-minded and positive in your aspirations and world’s perception.
