5.—You have lots of friends，right?

—Yes.　　　　I go，I am willing to make new friends.

A.Somewhere B.There

C.Everywhere D.Nowhere

解析：选C。答语句意为：不管我去哪里，我都喜欢结交新朋友。everywhere此处用作连词，引起状语从句。

6.Teenagers　　　　their health because they play computer games too much.

A.have damaged B.are damaging

C.damaged D.will damage

解析：选B。damage作动词，意为“损害;毁坏”。根据后句“因为他们玩电脑游戏太多”可知“青少年损害健康”是正在发生的动作，因此用现在进行时。

7.—Tom hasn’t come to class yet?

—What do you think　　　　?

A.did happen to him

B.has happened to him

C.he happened

D.he has happened

解析：选B。句中的do you think为插入语，去掉插入语，不影响句子的正常语序，故B正确。

8.Don’t play with electricity，or you may get an electric　　　　.

A.strike B.beat

C.shock D.knock

解析：选C。句意为“别玩电，要不你会触电的”。根据句意，C正确。Get a shock意思是“触电”。

9.—What’s the matter?It seems　　　　you’ve caught a cold.

—Oh，I’m just too tired.

A.as if B.ever since

C.because D.when

解析：选A。问句意为：怎么了?你好像感冒了。as if好像，符合题意。ever since从那以后;because因为;when当……时，均不符合句意。

10.The lifeboat was sent out to　　　　the sailors from the sinking ship.

A.shelter B.rescue

C.escape D.trap

解析：选B。考查动词辨析。句意为：救生艇被派出去救援沉船的水手。rescue营救。shelter掩蔽;escape逃脱，逃跑;trap使陷入困境。
