Teens don’t understand the big fuss(小题大做).As the first generation to grow up in a wired world,they hardly know a time when computers weren’t around,and they eagerly catch the chance to spend hours online,chatting with friends.So what?

But researchers nationwide are increasingly worried that teens are becoming isolated(孤寂),less skillful at person-to-person relationships,and perhaps numb(麻木) to the cheatings that are so much a part of the e-mail world.“And a teen’s sense of self and values may be changed in a world where personal connections can be limitless,”said Sherry Turkle.

Another researcher,Robert Kraut,said he’s worried about the “opportunity costs”(机会成本) of so much online time for youths.He found that teens who used computers,even just a few hours a week,showed increased signs of loneliness and social isolation.“Chatting online may be better than watching television,but it’s worse than hanging out(闲逛) with real friends,”he said.

Today’s teens,however,don’t see anything strange in the fact that the computer takes up a central place in their social lives.“School is busy and full of pressure.There’s almost no time to just hang out,”said Parker Rice,17.“Talking online is just catch-up time.”

Teens say they feel good about what they say online or taking the time to think about a reply.Some teens admit that asking someone for a date,or breaking up,can be easier in message form,though they don’t want to do so.But they insist there’s no harm.

1.The researchers argue that ______.

A.teens may develop a different sense of values

B.nothing is wrong with teens’ chatting online

C.teens can manage their social connections

At night, bats fly through the air, catching hundreds of insects and other small animals. But during the day, they hardly move at all. Instead, bats pass the time hanging upside down from a secret spot.

There are a couple of reasons why bats rest this way. First of all, it puts them in a position for takeoff. Unlike birds, bats can’t fly into the air from the ground. Their wings don’t produce enough lift to take off from a dead stop, and their hind legs are so small and underdeveloped that they can’t run to build up the necessary takeoff speed. Instead, they use their front claws to climb to a high spot, and then fall into flight.

During the hours when most enemies are active, bats gather where few animals would think to look and most can’t reach. This allows them to disappear from the world until night comes again. There’s also little competition for these resting spots, as other flying animals don’t have the ability to hang upside down. Bats have a unique physiological adaptation that lets them hang around this way without using any energy. For you to hold your fist around an object tight, you contract(紧缩) several muscles in your arm, which are connected to your fingers by tendons(腱)；as one muscle contracts, it pulls a tendon, which pulls one of your fingers closed. A bat’s talons(爪) close in the same way, except that their tendons are connected only to the upper body, not to a muscle. To hang upside down, a bat pulls its claws open with other muscles. To get the talons to take hold of the surface, the bat simply lets its body relax. The weight of the upper body pulls down on the tendons connected to the talons, causing them to hold tight. Therefore, the bat doesn’t have to do anything to hang upside down.

1.Bats hang upside down because________.

A. they haven’t developed a pair of strong claws

B. they can’t start to fly from the ground directly

C. they have no hind legs to support their body

D. they can’t find quiet places to stay during the day

2.The third paragraph tells us that bats’ hanging upside down_______.

A. is to save their energy for night movement

B. is a way to fight against flying animals

C. is a great way to hide from danger

D. is a skill to compete for the flying places

3.Why can bats hang upside down easily?

A. Because their upper body is light.

B. Because they have strong muscles.

C. Because their talons are linked to muscles tightly.

D. Because their tendons are linked to their upper body.

4.What is the passage mainly about?

A. The living habits of bats.

B. How and why bats hang upside down.

C. The importance of bats’ hanging upside down.

D. How bats use their energy at night.

Internet has become part of young people’s life. You can do lots of things on line such as chatting, sending messages and emails, getting useful knowledge and information, buying things without going to the shops, visiting cool websites, and so on. But it’s also easy to be cheated online. Here’s a story about a girl named Mary.

Mary is an 18-year-old girl who lives in New York. The people in Mary’s family are so busy that they hardly have time to be with her. In fact, Mary is quite lonely. So she spends a lot of time on QQ.

Last year Mary made a very special friend on QQ. His name was David and he lived in San Francisco. David was full of stories and jokes. He and Mary had a common interest in rock music and modern dance. So it always took them hours to talk happily on QQ and sometimes they even forgot the time. David sent Mary a picture of “himself”: he was a tall, good-looking young man with a big, happy smile. As time went by, they became good friends and often sent cards and small things to each other.

Before David’s birthday, Mary wanted to give him a surprise. She flew to San Francisco. But when Mary knocked on David’s door, she found that the special friend was a twelve-year-old boy named Jim!

Most people want to know how things are made.They honestly admit,however,that they hardly know a thing when it comes to understanding how a piece of music is made.Where a composer(作曲家) begins,how he manages to keep going—in fact,how and where he learns his trade—all are covered in complete darkness.The composer,in short,is a man of mystery(神秘).

One of the first things the common man wants to know about is the part inspiration(灵感) plays in a composer’s work.He finds it difficult to believe that composers are not much interested in that question.Writing music is as natural for the composer as eating or sleeping for all.Music is something that the composer happens to have been born for.

The composer,therefore,does not say to himself:“Do I feel inspired?”He says to himself:“Do I feel like working today?”And if he feels like working,he does.It is more or less like saying to himself:“Do I feel sleepy?”If you feel sleepy,you go to sleep.If you don’t feel sleepy,you stay up.If the composer doesn’t feel like working,he doesn’t work.It’s as simple as that.

1.What would be the best title for the text?

A.Composer:a man of mystery

B.Practice makes good music

C.Relation between sleeping and music

D.Music:product of nature

2.The words “covered in complete darkness” underlined in Paragraph 1 most probably mean _______.

A.difficult to be made                      B.without any light

C.black in color                            D.not known

3.Most people seem to think that a composer _______.

A.finds it difficult to write music

B.considers it important to have a good rest

C.should like to talk about inspiration

D.never asks himself very simple questions

4.The author will most probably agree that composers _______.

D.know a lot about eating and sleeping
