B

When I asked my daughter which item she would keep; the phone, the car, the cooker, the computer, the TV, or her boyfriend, she said “the phone”. Personally, I couldn’t do without the phone entirely, which makes me unusual, Because the telephone is changing our lives more than any other piece of technology.

Point 1 The telephone creates the need to communicate, in the same way that more roads create more traffic. My daughter comes home from school at 4:00 pm and then spends an hour on the phone talking to the very people she has been with at school all day. If the phone did not exist, would she have anything to talk about?

Point 2 The mobile phone means that we are never alone. “The mobile saved my life,” says Crystal Johnstone. She had an accident in her Volvo on the A45 between Otley and Skipton. Trapped inside, she managed to make the call that brought the ambulance to her rescue.

Point 3 The mobile removes our secret. It allows marketing manager of Haba Deutsch, Carl Nicolaisen, to ring his sales staff all round the world at any time of day to ask where they are , where they are going, and how their last meeting went.

Point 4 The telephone separates us. Antonella Bramante in Rome says, “We worked in separate offices but I could see him through the window. It was easy to get his number. We were so near——but we didn’t meet for the first two weeks!”

Point 5 The telephone allows us to reach out beyond our own lives. Today we can talk to several complete strangers simultaneously (同时地) on chat lines (at least my daughter does. I wouldn’t know what to talk about). We can talk across the world. We can even talk to astronauts (if you know any) while they’re space-walking. And, with the phone line hooked up to the computer, we can access the Internet, the biggest library on Earth.

45．How do you understand ‘Point 1 —The telephone creates the need to communicate,…’？

A．People don’t communicate without telephone.

B．People communicate because of the creating of the telephone.

C．People communicate more since telephone has been created.

D．People communicate more because of more traffic.

46．Which points do you think support the idea that phones improve people’s life?

a．Point 1． b．Point2． c．Point3． d．Point 4． e．Point 5．

A．c, d B．a, e C．a, c D．b, e

47．It is possible to talk to several complete strangers simultaneously through .

A．the TV screen B．a fax machine

C．the phone line hooked up to the computer D．a microphone

48．The best heading for the passage is .

A．Phone Power B．Kinds of Phone

C． How to Use Phones D．Advantage of Phones

B

When people lose legs after accidents or illnesses, emergency care and artificial limbs（假肢）often allow them to walk again. Newts （蝾螈） in the same situation, on the other hand, can grow limbs back on their own! Scientists have known for a long time that certain animals can re-grow limbs, but they haven’t quite figured out how these creatures do it.

Researchers have now come up with some new ideas. Their work may give people the ability to re-grow lost limbs. The researchers started with two simple experiments：when you cut a newt’s leg at the ankle, only the foot grows back；when you cut off a leg at the very end, the whole leg grows back. In both cases, the re-growth begins with stem cells. Stem cells can develop into nearly any type of cell in the body.

How do a newt’s stem cells know when to grow only a foot and when to re-grow a whole leg?

This question relates to another mystery. In newt’s, a cut-off leg will grow back only if the nerve bundle（神经束）in it also grows back , but if something prevents the nerve bundle from growing, the stem cells at the wound won’t re-grow a new leg.

In its study, a British team focused on a protein called n-AG. When the team prevented nerves in a limb from growing, but added the n-AG protein to stem cells in the limb, the limb still re-grew. That protein seems to guide limb re-growth. People have proteins that are similar to n-AG. Further research into these materials may someday help human limbs recover by themselves.

40. In the experiments, the researchers cut off a newt’s foot or leg to find out _____.

A. what stem cells were B. whether they would grow back

C. how long it would take to re-grow D. how they would re-grow

41. A newt will re-grow its leg if _____.

A. its ankle was cut off but the nerve bundle was good

B. its leg was cut off and the nerve bundle stopped growing

C. its leg was cut off and the nerve bundle could grow back

D. its ankle and the nerve bundle were cut off

42. What do the underlined words “these materials” refer to?

A. Nerve bundles and proteins. B. Proteins similar to n-AG.

C. Stem cells and proteins. D. Stem cells and nerve bundles.

43. The first sentence of the passage _____.

A. acts as a lead–in B. shows where researchers got their new ideas

C. states the author’s opinion D. describes the result of researchers’ studies
