专升本（英语）模拟试卷408
词汇和语法结构
1.The room is in a terrible dirty surroundings; it ______ cleaned.(A)
A. can’t have been
B. shouldn’t have been
C. mustn’t have been
D. wouldn’t have been
解析：句意：房间乱极了，不可能打扫过。句子前半部分“房间乱极了”是前提，后半部分应该是对这种情况做出的一种猜测性判断，且带否定意味，应用否定形式can’t have done，表示不可能做某事。shouldn’t have done意为本不应该打扫，而实际上已经打扫过了，与句意不符。
2.We forgot to bring our tickets, but please let us enter, ______?(B)
A. do you
B. will you
C. can we
D. shall we
解析：句意：我们忘了带票了，请让我们进去，好吗? let us表示“请求”，反意疑问句是will you／won’t you；而let’s表示建议，反意疑问句是shall we。
3.The traditional approach ______ with complex problems is to break them down into smaller, more easily managed problems.(A)
A. to dealing
B. in dealing
C. dealing
D. to deal
解析：句意：处理复杂问题的传统方法是将其分解成更容易处理的小问题。approach to为固定搭配，to在这里是介词，后面应跟动名词。
4.I’d like to ______ him to you for the job. He is very clever and capable.(C)
A. refer
B. suggest
C. recommend
D. propose
解析：句意：我愿意向你推荐他做这份工作，他非常聪明又有能力。refer参考，查询；suggest建议，提议；recommend推荐，介绍；propose提议，提名。
5.The book is worth ______.(C)
A. read
B. being read
C. reading
D. having read
解析：句意：这本书值得一读。be worth后的动词通常用动名词形式，表示“值得……”，而且用主动形式来表达被动意义。
6.Shelly had prepared carefully for her biology examination so that she could be sure of passing it on her first ______.(B)
A. intention
B. attempt
C. purpose
D. desire
解析：句意：雪莱已为生物考试做了精心准备，以确保一次通过。intention意图，打算；attempt尝试，试图；purpose目的；desire渴望，愿望。
7.The ancient Egyptians are supposed ______ rockets to the moon.(C)
A. to send
B. to be sending
C. to have sent
D. to have been sending
解析：句意：据猜测，古埃及人曾向月球发射过火箭。send为短暂性动词，不能用进行时态，所以B、D两项错误。A项和C项的区别在于不定式的时态，句首表示时间概念的ancient表明不定式动作在句子谓语动作之前发生，不定式须用完成式，故C项正确。
8.The store had to ______ a number of clerks because sales were down.(B)
A. lay out
B. lay off
C. lay aside
D. lay down
解析：句意：因为销售额下降，商店不得不裁掉大量雇员。lay out布置，展开；lay off解雇，停止工作；lay aside放在一边，留待后用；lay down放下，阐述。
9.All the students in this class passed the English exam ______ the exception of Li Ming.(D)
A. on
B. in
C. for
D. with
解析：除了李明，该班学生全部通过了英语考试。with the exception of…为固定搭配，意为“除……以外”。
10.Young adults ______ older people are more likely to prefer pop songs.(D)
A. other than
B. more than
C. less than
D. rather than
解析：句意：喜欢流行歌曲的可能是年轻人而不是老年人。可首先排除B、C两项，因为主句中已经有比较级标志词more。other than表示“除了”，young adults和older people不存在包容关系，即整体和局部的关系，所以也错。rather than而不是，符合题意。
11.______ you eat the correct foods ______ be able to keep fit and stay healthy.(B)
A. Only if; you will
B. Only if; will you
C. Unless; you will
D. Unless; will you
解析：句意：只有正确饮食，你才能保持身体健康。从句意可知，unless不符合题意，若选D的话，应当在you will后加上not。only if表示条件，意为“只有”。当only if置于句首时，主句要部分倒装，故选B。
12.______ right now, she would get there on Sunday.(C)
A. Would she leave
B. If she leaves
C. Were she to leave
D. If she had left
解析：句意：如果她马上出发，星期天就能到那儿。从结构上看，主句谓语为“would+动词原形”，那么条件句谓语动词为“were to”或“should+动词原形”，省略if时，were或should提前构成倒装结构。显然C项正确。
13.It’s already 5 o’clock now. Don’t you think it’s about time ______?(C)
A. we are going home
B. we go home本文档预览：3500字符，共18995字符，源文件无水印，下载后包含无答案版和有答案版，查看完整word版点下载
