专八模拟改错(9)What is a black hole? Well, it is difficult to answer the question,as the terms we would normally use to describe a scientific phenomenon _1_are adequate here. Astronomers and scientists think that a black hole is _2_a region of space which matter has fallen and from which nothing can _3_escapenot even light. But we cant see a black hole. A black hole _4_exerts a strong gravitational pull and yet it has no matter. It is onlyspaceor thus we think. How can this happen? _5_The theory is that some stars explode when their density increasesto a particular point; they “collapse” and sometimes a supernova occurs.The collapse of a star may produce a “White Dwarf” of a “neutronstar”a star which matter is so dense that if continually shrunk by the force of _6_its own gravity. But if the star is very large, this process of shrinking maybe so intense that a black hole results in. Imagine the earth reduced to the _7_size of a marble, but still having the same masses and a stronger _8_gravitational pull, and you have some ideas of the force of a black hole. _9_And no matter near the black hole is sucked in. _10_专八模拟改错(8)Whenever you see an old film, even one made as little as ten years before, you cant help being strucked by the_1_appearance of the women taking part. Their hair styles and make-up look date; their skirts look either too long or too_2_short; their general appearance is, in fact, slightly ludicrous.The men taking part, on other hand, are clearly recognizable._3_There is nothing about their appearance to suggest that they belong to an entire different age. This illusion is created _4_by changing fashions. Over the years, the great minority of men _5_have successfully resisted all attempts to make it change their _6_style of dress. The same cannot be said for women. Each year, a fewer so-called top designers in Paris and London lay down_7_on the law and women around the world run to obey. The _8_decrees of the designers are unpredictable and dictatorial. Sometime they decide arbitrarily, that skirts will be short and _9_waists will be height; hips are in and buttons are out. _10_.专八模拟改错(7)We use language every day. We live in a world of words. Hardly anymoment passes with someone talking, writing or reading. Indeed, _1_languages is most essential to mankind. Our lives increasingly dependon fast and successful use of language. Strangely enough, we know _2_more about things around us than on ourselves. For example, language _3_is species specific, that is, it is language that differs human from _4_animals. However, we do not know yet how exactly we inquire language _5_and how it is possible for us to perceive through language; nor we _6_understand precisely the combinations between language and thought, _7_language and logic, or language and culture; still less, how and whenlanguage started. One reason for this inadequate knowledge of languageis that we, like language users, take too many things for granted. _8_Language comes to every normal person so naturally that a few _9_of us stop to question what language is, much less do we feel thenecessity to study it. Language is far more complex than most peoplehave probably imagined and the necessity to study it is far greater thansome people may have assured. Linguistic is a branch of science which _10_takes language as its object of investigation.专八模拟改错(6)For the last fifteen or twenty years the fashion in criticism or appreciation of the arts have been to deny the existence of any valid criteria and to make the _1_words “good” or “bad” irrelevant, immaterial, and inapplicable. There is no such thing, we are told, like a set of standards first acquired through experience and _2_knowledge and late imposed on the subject under discussion. This has been a _3_popular approach, for it relieves the critic of the responsibility of judgment and the public by the necessity of knowledge. It pleases those resentful of disciplines, it _4_flatters the empty-minded by calling him open-minded, it comforts the _5_confused. Under the banner of democracy and the kind of quality which our forefathers did no mean, it says, in effect, “Who are you to tell us what is good or bad?” This is same cry used so long and so effectively by the producers of mass _6_media who insist that it is the public, not they, who decide what it wants to hear _7_and to see, and that for a critic to say that this program is bad and that program is good is pure a reflection of personal taste. Nobody recently has expressed this _8_philosophy most succinctly than Dr. Frank Stanton, the highly intelligent _9_president of CBS television. At a hearing before the Federal Communications Commission, this phrase escaped from him under questioning: “One mans mediocrity _10_is another mans good program”.专八模拟改错(4)Home, sweet home is a phrase that express an essential attitude in the United States. Whether the reality of life in the family house is sweet or no sweet, the cherished ideal of home _1has great importance for many people.This ideal is a vital part of the American dream. This dream, dramatized in the history of nineteenth century European settlers of American West, was to find a piece of place, build a house _2for ones family, and started a farm. These small households were _3portraits of independence: the entire family- mother, father, children,even grandparents-live in a small house and working together to _4support each other. Anyone unde
