大学英语每日一练(7-29)

121. Compared with last year, our summer crops output has increased ________ 10 percent.

A. by

B. for

C. in

D. to

【答案】A。解析：考查介词。句意：与去年相比，我们今年的夏季粮食产量增加了 10%。动词 increase 后使用 by 表示增加了，使用 to 表示增加到。因此本题答案为 by。故选A。

122. The firefighters ________ the fire before the helicopter ________.

A. had put out; arrived

B. were putting out; arrived

C.put out; arrived

D. had been put out; arrived

【答案】A。解析：考查动词时态。句意：在直升飞机到来之前，消防队员已经将火扑灭了。救火的动作发生在前，故“救火”的时态用过去完成时，“到来”的时态用一般过去式。故选A。

123. Like the Olympics, the World Cup takes place ________ years.

A. every four

B. each fourth

C. each four

D. every fourth

【答案】A。解析：考查数词。句意：像奥运会一样，世界杯每四年举行一次。“每隔……”的表达法有： every +基数词 +复数名词;every +序数词+单数名词。故选A。

124. As time went on, Einstein’s theory ________ to be correct.

A. proved

B. proves

C. is proved

D. was proved

【答案】A。解析：考查被动语态。句意：随着时间的推移，爱英斯坦的理论证明是正确的。prove 证明是，被证实，可以作为实义动词或连系动词。作为实义动词时可以用被动;prove作为系动词时，后跟形容词或跟“to be+形容词”，此时无被动语态，为主动表被动。该题中prove是一个连系动词，没有被动形式，该句时态应该是一般过去时态。故选A。

125. If we climb up to the top of the mountain, we’ll have ________ view.

A. the better

B. a best

C. a better

D. the best

【答案】C。解析：考查形容词比较级。句意：如果我们爬到山顶，我们将有更好的视野。由句意可知，应用比较级，排除B、D。have a good view有好的视野，泛指需要用a，又因good的比较级是better。故选C。

126. It is required that students ________ at least two clubs in the university.

A. will attend

B. would attend

C. attend

D. are to attend

【答案】C。解析：考查虚拟语气。句意：按要求学生们在大学里最少要参加两个社团。在“It is /was +表语+主语从句”句型中，当主句的谓语为“be + required/demanded/ordered/requested等”时，从句要用虚拟语气，其谓语动词的形式为“should +动词原形”，should可以省略。故选 C。

127. ________ the program, they have to stay there for another two weeks.

A. Not having completed

B. Not completed

C.Not completing

D. Having not completed

【答案】A。解析：考查非谓语。句意：没有完成这个项目，他们不得不在多待两周。They和complete之间是主动关系，且动作发生在have to stay之前，故用其完成式;又因非谓语动词的否定形式要在非谓语前直接加not。故选A。
