15．-Whose pencil-box is this？
-Oh，it's ____________．I was looking for it everywhere．
A．myB．yoursC．meD．mine

分析 -這是誰的鉛筆盒？-哦，它是我的，我正到處找它．

解答 答案：D    本題考查物主代詞．根據(jù)問句"Whose pencil-box is this？"可知是問"pencil-box"的物主．再根據(jù)"I was looking for it everywhere"可以判斷是"我的"因為it's 的表語中不含名詞，故用名詞性物主代詞．故選D

點評 先分析句子的意思，然后分析用哪一種代詞，再根據(jù)：名詞性物主代詞=形容詞性物主代詞+名詞，解答．

5．1  I’ve been working as a professional clown（小丑）for nearly two years．Before that，I was an actor for nine years．I was never famous，but I was quite successful!I changed jobs because I wanted to do more in life than make people laugh．What if I could help people，too？
As a clown，I try to encourage sick chileren in hospital to laugh and smile．When you laugh，your mind and body relax．Clearly，people who laugh more don’t have as many colds or other problems!Children who laugh a lot often get better results in their studies，too．
It isn’t an easy job．Not all sick children get better，and sometimes I come home and cry．But I always go back to work the next day with my red nose on．I don’t earn much money as a clown，but I feel very lucky to work with such brave，wonderful patients．
2  I became a laughter yoga（瑜伽）teacher more than two years ago．Before that，I was a
dentist!My job was very difficult，and I used to feel fed up．Now I still improve people’s
health，but everything else is completely different．Everyone has fun in a laughter yoga
class，including the teacher!
No，laughter isn’t“magic”．It doesn’t prevent all illness，keep you young，or make you
beautiful．But did you know that isn’t ana excellent kind of exercise？You move your whole
body when you laugh!
Sometimes I worked with famous people．It’s true that being rich can be stressful!Some famous people can be unpleasant at times，but I try to change their bad feelings．Laughter is
excellent for people like musicians，artists and writers，because it helps people to be more creative．

17．TOKYO，JAPAN--What do you do when you see a cockroach （蟑螂）？Do you hit it with a newspaper？Do you step on it？
When researchers at Tokyo University see a cockroach，they take the remote control and make the cockroach turn around，run left or right，or go forward．These scientists are changing the cockroaches into robots．Each cockroach has a very small pack that has in it a microprocessor（微處理器）．Then researchers can send signals from the remote control to the pack．The signals control the movements of the cockroaches．
Why does anyone want to control a cockroach？"Insects can do many things that people can't，"says Isao Shimoyama，head of robot research at Tokyo University．In a few years，he says，these robot insects will carry very small cameras．They will be able to move through earthquake rubble（瓦礫）to look for people or move under doors to find information about someone．
This may seem strange，but the Japanese government thinks the research is very important．The government is giving the scientists $ 5million for this research．
First，the researchers breed （培育）hundreds of cockroaches．They use only the American cockroach because it is bigger and stronger than other cockroaches．Then they choose the best cockroaches and remove their wings and antennae（觸須）．They put small packs where the antennae were．The packs weigh about three grams，or about two times the weight of the cockroaches themselves．"Cockroaches are very strong，"says Ralph Holzer，who is a researcher at Tokyo University．"They can lift 20times their own weight．"
With a remote control，the scientists send signals to the packs．When a cockroach gets the signal，it moves．The problem is that the cockroaches don71always move in the right direction．
37．The scientists are changing the cockroaches into robots becauseA．
A．they want cockroaches to do things people can't in the future
B．they want to control the movements of the cockroaches
C．they want cockroaches to take photos of the earthquakes
D．they want to send signals to the packs on the cockroaches
38．What can cockroaches do to help people？
A．They can lift 20times their own weight．
B．They can help people to carry very small cameras．
C．They can breed hundreds of cockroaches．
D．They can search for those people in rubble after an earthquake．
39．Scientists control cockroaches'movementsB．
A．by removing their wings       B．by sending signals from the remote control
C．by using very small camerasD．by removing their antennae
40．What problem do the rcscarchcrs meet with？
A．The cockroachcs sometimes clon；t move．
B．The cockroachcs sometimes move in the wrong direction．
C．The cockroachcs arc too big to move through earthquake rubble．
D．The cockroachcs can only lift 20times their own weight．
