of their own DHEAS even if they aren’t wealthy, by leading more DHEAS-friendly lives—more exercise, more friendships and more hobbies—though, as the article notes, production of DHEAS is greatest in childhood and teenage years, gradually

thereafter.

Most parents, I suppose, have had the experience of reading a bedtime story to their children. And they must have realized how difficult it is to write a
1
children’s book. Either the author has aimed too
2
, so that the children can’t follow what is in his (or more often, her) story, or the story seems to be talking to the
3
. 文学与艺术 D. good C. high B. readers
The best children’s books are neither very difficult nor very simple, and satisfy both the 4
who hears the story and the adult who
5
it. Unfortunately, there are in fact few books like this, so the problem of finding the right bedtime story is not
6
to solve. A. child D. reads B. easy
This may be why many
books regarded as
7
of children’s literature were in fact written for
8
. “Alice’s Adventure in Wonderland” is perhaps the most
9
of this. C. obvious D. works A. adults
Children, left for themselves, often

the worst possible interest in literature. Just leave a child in

12 way, or have a look at most children’s comics, full of stories and jokes which are the 13
of teachers and right-thinking parents. D. library B. imaginative B. show C. objections
Perhaps we parents should stop trying to brainwash children, and children should not be made to
14
our taste in literature. After all, children and adults are so
15
that we parents should not expect that they will enjoy the same books. So I suppose we’ll just have to compromise over that bedtime story. B. accept C. different (25)
Many of the world’s pollution problems have been caused by the crowding of large groups of people into the cities. Supply for the
1
of the people leads to further pollution by industry. If the rapid increase of world population
2
at the present rate, there may be much greater harm to human beings. Some scientists speak of the
3
in numbers of people as “population pollution”. 人口与环境 A. needs B. continues A. increase
About 2,000 years ago, the world population was
4
about 250 million. It
5
a billion in 1850. By 1930 the population was two billion. It is now six billion. It is
6
to double by the year 2024. If the population continues to grow at the same
7
, there will be 25 billion people in the world a hundred years from now. D. probably D. reached C. expected A. rate
Man has been using the earth’s

is how to control the growth of the population.
C. problem C. gone A. resources The
11
supplies in the world will be far from enough to
12
the human population if the 13
rate of increase continues. There is already over-crowding in many

I know a man who has a

collection. A short time ago he bought a

He has almost 600 of them but I

That is what a hobby

Music comes in many forms; most countries have a style of their own. At the turn of the century when jazz was born, America had no prominent
1
of its own. No one knows exactly when jazz was
2
,or by whom. But it began to be heard in the early 1900s. 音乐艺术 D. style C. invented
Jazz is America’s contribution to
3
music. In contrast to classical music, which
4
formal European traditions, jazz is spontaneous and free form. It bubbles with energy,
5
the moods, interests, and emotions of the people.
A. expressing B. follows C. popular
In the 1920s jazz

like America, as it does today. The

D. formed B. procession
But on the way home the mood changed, spirits lifted. Death had removed one of their

13
to be alive. The band played
14
music, improvising(即兴表演) on
the tunes

at the funeral. This music made everyone want to dance. It was an early form of jazz.

From childhood to old age, we all use language as a means of broadening our knowledge of ourselves and the world about us. When humans first
1
,they were like newborn children, unable to use this
2
tool. Yet once language developed, the possibilities for human’s future
3
and cultural growth increased. 语言学习 B. evolved A. achievements
A. valuable
Many linguists (语言学家) believe that evolution is
4
for our ability to produce and use language. They
5
that our highly-evolved brain provides us with an innate (先天的）language ability not found in lower
6 .
D. responsible
C. claim
B. organisms
Supporters of this innateness theory say that our
7
for language is inborn, but that language itself develops gradually, as a function of the growth of the brain during childhood. Therefore there are critical
8 times for language development. B. biological A. potential
Current
9
of innateness theory are mixed, however, evidence supporting the existence of some innate abilities is undeniable. Indeed, more and more schools are discovering that foreign languages are best taught in
10
grades.
A. reviews D. lower
Young children often can learn several languages by being
11
to them, while adults have a much harder time learning another language once the
12
of their first language have become firmly fixed.
B. exposed C. rules Although some aspects of language are undeniably innate, language does not develop automatically in a vacuum（真空）. Children who have been
13
from other human beings do not possess language.
D. isolated This shows that 14 with other human beings is necessary for proper language development. Some linguists believe that this is even more basic to human language
15 than any innate capacities. D. interaction A. acquisition

Imagine always having to keep away from the cakes at birthday parties. I can tell you that even
adult people often don’t really understand why you really shouldn’t enjoy just a little
4
, which is made harder by the fact that you really want to do so. So, why not listen to music or take a
5
walk downtown to help a few kids have a better life?
B. piece C. relaxing Don’t be
6
by claims like ‘fat-free’ and ‘only 50 calories’. Look for what they don’t tell you and try to

impression that they’re healthier than they really are. Some ‘healthy’ ready meals are
