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__
escape—not even light. But we can’t see a black hole. A black hole __4__
exerts a strong gravitational pull and yet it has no matter. It is only
space—or thus we think. How can this happen? __5__
The theory is that some stars explode when their density increases
to 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 may
be 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__

Whenever you see an old film, even one made as little as ten years before, you can’t 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__.

We use language every day. We live in a world of words. Hardly any
moment passes with someone talking, writing or reading. Indeed, __1__
languages is most essential to mankind. Our lives increasingly depend
on 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 when
language started. One reason for this inadequate knowledge of language
is 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 the
necessity to study it. Language is far more complex than most people
have probably imagined and the necessity to study it is far greater than
some people may have assured. Linguistic is a branch of science which __10__
takes language as its object of investigation.

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 man’s mediocrity __10__
is another man’s good program”.
