单项选择

1. _______made the school proud was _______ more than 90% of the students had been admitted to key universities.

A.What;because

B.What;that

C.That;what

D.That;because

解析：第一空为what引导的主语从句，what在从句中作主语；第二空为that引导的表语从句，that不作句子成分。表语从句所表达的是一个事实，而不是原因，因此不能选A。

答案：B

2. _______she couldn't understand was _______ fewer and fewer students showed interest in her lessons.

A.What;why

B.That;what

C.What;because

D.Why;that

解析：主语从句缺少主语，故选what；根据句意，她所不能明白的是为什么、而不是因为什么越来越少的学生对她的可感兴趣，所以，表语从句须由why引导而不能由because引导。答案：A

3. _______has helped to save the drowning girl is worth praising.

A.Who

B.The one

C.Anyone

D.Whoever

解析：whoever=anybody who,强调“人”，既作从句的主语，又作整个句子的主语；who在本句中只能作从句的主语；B、C两项后加that才对。

答案：D

4.A satellite is _______object traveling in orbit round another object in space.

A.the;/；the

B.an;an;a

C.the;an;a

D.an;an;/

解析：本题考查冠词的用法，in space “在太空中”，space前不加冠词；object与orbit是指类别，故用an。

答案：D

5.The camera（相机）isn't _______.It still _______where I _______ it a month ago.

A.missed;lies;lay

B.missing;lies;laid

C.gone;lays;laid

D.lost;lays;lay

解析：第一个空表示“丢了”，B、C、D三项均可，missed不能表示此意，故排除A项；第二个空lie表示“位于”，而lay表示“放置”；至此C,D两项也可以排除掉了。第三空lay（laid）是及物动词，意为“放置”。

答案：B

6.Shops should _______open till late in the evening.

A.be remained

B.remain

C.leave

D.keeps

解析：remain作系动词时后接形容词、分词、名词、介词短语等，构成系表结构，表示“（继续）保持，仍然处于某种状态”。A、D两项动词形式不对；C项用作使役动词缺少对象，因此要说成Shops should be left open.在语法上才对。

答案：B

7.They _______that he works all night.

A.expected

B.wished

C.hoped

D.required

解析：require可接that-clause，从句中的谓语用“should+动词原形”，should可省略；expect 和hope后接宾语从句时，从句的谓语动词用正常的形式；wish接宾语从句，从句的谓语动词用虚拟形式，即时态要产生变化。

答案：D

8.The_______is doing an experiment in _______ with some_______.

A.chemistry; chemist; chemicals

B.chemicals; chemistry; chemist

C.chemist; chemistry; chemicals

D.chemistry; chemicals; chemist

解析：chemist 指“药剂师或化学家”，chemistry 意为“化学”，chemicals 指“化学物质”。答案：C

9.That's the best way you thought of _______ into dangerous areas.

A.stopping people to get

B.to stop people getting

C.keeping people getting

D.preventing people in getting

解析：句中you thought of...是中心词way的后置定语从句，way是介词of的宾语；空格中缺少的也是定语，而不是of的宾语。stop sb.doing sth.是固定短语。

答案：B

10.—How do you find the lecture by Mr Lee?
