“ Teenager ” is the new term being used in the UK to describe kids at eithe-132 or 10-13 years old.

More and more compa nies are begi nning to create products and services for tee n agers. The Disney compa ny sells music and film to tee nagers and their pare nts. You can get everyth ing from bran ded lun chboxes and mobile phone covers, to monthly fan magazines and clothing. It 'als about sales, which suggests that teenagers must have more mon ey, freedom and in flue nee upon their pare nts tha n they ' ve ever had before.

Most kids in the UK today get more pocket money tha n kids did a decade ago. Pare nts have more money to give their kids tha n previously, since pare nts are havi ng fewer childre n. In additi on, the divorce rate in the UK is continually rising and parents spend less time with their children than they used to, so many parents try to compe nsate (弥补)by buying prese nts for their childre n. It ' s a bad habit for both pare nts and kids to get in to, but pare nts are un der con sta nt pressure from commercial marketi ng and the requests of their childre n.

UK kids today are very media and computer-literate (熟练的).A lot of kids have a TV, if not a computer, in their bedrooms. They can get much more information about life and the world. They may have experieneed a lot in life as well, since 24% of UK

kids live in sin gle-pare nt families, so people now say that “ kids are gett ing older youn ger ” . With such maturity (成熟)at such a young age, it ' s no won der tee nagers are able to in flue nce their pare nts and have more freedom tha n previous gen erati ons.

UK teenagers never used to be worried about spending money on clothes. That ' s changed. Now, they are much more fashion conscious (有意识的)and concerned about their image. Many teenagers out grow (年长而不再需要)the bright colors and fashions of their teenage years and go for something darker and more rebellious (叛逆的).

Surely none of the above is a good thing. The UK government is certainly concerned, and for that reason has strict laws preve nting compa nies from clearly market ing their products and services at childre n.

25. Why are more products and services created for tee nagers?

A. Because childre n have more money to buy them.

B. Because it is better to study music from an early age.

C. Because childre n educati on is beco ming more importa nt.

D. Because more compa nies are creati ng products and services.

26. Teen agers have more freedom due to the follow ing facts EXCEPT that ___ .

A. they become mature at a youn ger age

B. they have a lot of experiences in life

C. they know more in formatio n tha n kids before

D. their pare nts can not in flue nce them any more

27. What is the purpose of the passage?

A. To teach a new word “teenager” .

B. To introduce a new phenomenon (现象).

C. To advise parents to

care about their kids. D. To blame today' s young people.

We once had a poster competition in our fifth grade art class.

“ You could win prizes, ” our teacher told us as she wrote the poster in formati on on the blackboecpassed out sheets of con struct ion paper while con ti nuing, “ The first prize is ten dhallairstoYioaji sture that

the w ords on the blackboard appear somewhere on your poster. ”

We studied the board carefully. Some of us looked with one eye and held up certain colors against the blackboard, rock ing the sheets to the right or left while we conjured up our desig ns. Others twisted (揉搓)their hair around their fin gers or chewed their erasers while deep in thought. We had pla ns for the ten-dollar gra nd prize, each and every one of us. I'm going to spe nd mine on can dies, while ano ther practiced look ing serious, wise and rich as if he would hopefully be announced (宣布)winner.

Everyone in the class made a poster. Some of us used parts of those fancy (华丽的)paper napkins, while others used nothing but colored con struct ion paper. Some of us used big desig ns, and some of us preferred to gather our art tidily down in one corner of our poster and left the space in order to draw the viewer ' s attention to

it. Some of us would wander (游荡)past the good students ' desks and then return to our own projects with a growing sense of hopelessness. It was yet another grown-up trick (把戏)of the sort they seemed especially fond of, making all of us believe we had a fair chance, and then always —always—rewarding the same old winners.

I believe I drew a sailboat, but I can ' t say tlyatl withdedttaiatdmired it. I determined it to be the

very best of all of the posters I had see n, and the n I tur ned it in.

Minu tes passed.

No one came along to give me the grand prize, and the n some one distracted (使分心)me, and Iprobably n ever would have thought about that poster aga in.

I was still sitt ing at my desk, thi nking. What poster? When the teacher gave me an en velope witha ten-dollar bill in it and

every one in the class applauded for me.

Not long ago, people thought babies were not able to learn things un til they were five or six mon ths old. Yet doctors in the Un ited States say babies begi n lear ning on their first day of life.

Scie ntists n ote that babies are stron gly in flue need by their environment. They say a baby will smile if her mother does someth ing the baby likes. A baby lear ns to get the best care possible by smili ng to please her mother. This is how babies lear n to connect and com muni cate with other huma n bein gs.

One study shows that babies can lear n before they are born. The researchers placed a tape recorder on the stomach of a pregnant (怀孕的)woman. Then, they played a recording of a short story. On the day the baby was born, the researchers attempted to find if he knew the sounds of the story repeated while in his mother. They did this by placi ng a device (设备)in the mouth of the new born baby.

The baby would hear the story if he moved his mouth one way. If the baby moved his mouth the other way, he would hear a different story. The researchers say the baby clearly liked the story he heard before he was born. They say the baby would move his mouth so he could hear the story aga in and aga in.

Ano ther study shows how mothers can stron gly in flue nee social developme nt and Ian guage skills in their childre n.

Researchers studied the childre n from the age of one month to three years. The researchers attempted to measure the sensitivity (体恤)of the mothers. The women were considered sensitive if they supported their children ' s activities and did not interfere (干涉)unnecessarily. They tested the children for thinking and Ianguage developme nt whe n they were three years old. Also, the researchers observed the wome n for sig ns of depressi on (抑郁).

The childre n of depressed wome n did not do as well in tests as the childre n of wome n who did not suffer from depressi on. The childre n of depressed wome n d id poorly in tests of Ian guage skills and un dersta nding what they hear.

These children also were less cooperative (合作的)and had more problems dealing with other people. The researchers no ted that the sen sitivity of the mothers was importa nt to the in tellige nee developme nt of their childre n. Childre n did better

whe n their mothers were cari ng, even whe n they suffered from depressi on.

32. According to the passage, which of the following is NOT the factor that influences intelligence development in babies?

A. The environment.

B. Mother ' s sensitivity.

C. Their moveme nt.

D. Educati on before birth.

33. What is the purpose of the experiment in which newborn babies heard the stories?

B. To prove that babies can learn on the first day they are born.

C. To indicate early education has a deep effect on the babies ' Ianguage skills.

As the old saying goes, laughter is the best medicine. 36 However, doctors have begun to look into laughter and the effects i t has on the human body. They have found that laughter really can improve people ' s health.

37 People watched funny films while doctors checked their heart, blood pressure, breathi ng and muscles. It was found that laughter has similar effects to physical exercise. It in creases blood pressure, makes the heart beat quicker and makes people breathe deeper; it also works several groups of muscles in the face, the stomach, and even the feet. 38 Other tests have show n that laughter appears to be able to reduce the effect of pain on the body. In one experime nt, doctors produced pain in groups of stude nts who liste ned to differe nt radio programs. 39 The

reas on why laughter can reduce pain seems to be that it helps to produce a kind of chemical in the brain which reduces both stress and pain.…

40_ They try to improve their patients ' condition by encouraging them to laugh. They have found that even if their patie nts do not really feel like laugh ing, making them smile is eno ugh to produce ben eficial (有益的) effects similar to those caused by laughter.

A. Therefore, people are taught to laugh.

B. Laughter is closely related to good health.

C. If laughter exercises the body, it must be ben eficial.

D. Un til recen tly, few people took the say ing seriously.
