陕西专升本（英语）模拟试卷27
词汇语法
1.Every means______but it’ s not so effective.(B)
A. have been tried
B. has been tried
C. have tried
D. has tried
解析：means意为“方法，手段”时，为可数名词。“every+可数名词”作主语时，谓语动词用单数形式，所以排除A、C两项。根据句意可知，means和try之间为逻辑上的动宾关系，所以应用被动语态。故选B。
2._____is known to all, too much stress can cause disease.(D)
A. Which
B. That
C. It
D. As
解析：分析句子结构可知，逗号之前为非限制性定语从句，指代后面句子的内容。从句成分不完整，缺少主语，所以应用关系代词as来引导。which引导的非限制性定语从句不可位于句首；it，that均不能引导非限制性定语从句。也可将as is known to all(众所周知)当作固定搭配。类似的用法还有as is often the case(情况往往是这样)，as often happens(事情往往如此)，as is mentioned above(正如上面所提到的)等。故选D。
3.His proposal that the direction of the company’ s development______sounds reasonable.(B)
A. must change
B. be changed
C. changes
D. is changed
解析：当suggestion，proposal，advice，order，request等表示“建议、要求、命令”的名词后有同位语从句时，从句一般用虚拟语气，谓语动词用“should+动词原形”的形式，should可以省略。分析句子结构可知，proposal和sounds之间是同位语从句，是对proposal的解释说明，所以从句的谓语动词应用“should+动词原形”的形式，should可以省略。且change和the direction of the company’s development之间为逻辑上的动宾关系，所以应用被动语态。故选B。
4.Only after the storm was over______.(A)
A. could we start off
B. we could start off
C. had we started off
D. we had started off
解析：当“only+状语”位于句首时，主句应部分倒装，即将谓语中的助动词、系动词be、情态动词提至主语之前。C项表示的是“出发”发生在“暴风雨停了”之前，不符合句意。故选A。
5.The number of the employees in our company is______that in theirs.(A)
A. twice as large as
B. twice as many than
C. as twice many as
D. as twice as
解析：英语中表示倍数的句型通常有三种：(1)倍数+the+n．(size／weight…)+of；(2)倍数+as+形容词或副词原级+as；(3)倍数+形容词或副词比较级+than。选项A符合第二种情况，因此为正确答案。句子的主语为“The number of(……的数量)”，应用形容词large修饰。故选A。
6.We can’t______one to change the habits in a short time.(C)
A. hope
B. wait
C. expect
D. imagine
解析：hope：希望；wait：等待；expect：期望，盼望；imagine：想象。根据句意可知，选C。
7.Is there a connection between______you eat and maintaining good health?(C)
A. that
B. which
C. what
D. whatever
解析：分析句子结构可知，空处引导的是宾语从句，且从句中eat后面缺少宾语，所以应用连接代词what来引导。故选C。
8.______on the grassland, I watched the clouds and listened to the singing of the birds.(A)
A. Lying
B. Laying
C. Lied
D. Laid
解析：本题首先要区分动词lie和lay的词义。lie作动词时，意为“躺，位于，说谎”；lay作动词时，意为“放置，下蛋”。根据句意可知，此处意为“躺下”，同时又作句子的状语，lie与其逻辑主语I为主谓关系，所以应用现在分词lying。故选A。
9.Look’ The man in the bar behaves strangely. He______a lot of alcohol.(D)
A. should have drunk
B. needn’ t have drunk
C. could have drunk
D. must have drunk
解析：should have done表示本应该做某事而实际上没有做，意为“本该……”；needn’t have done表示本不需要做某事而实际上却做了，意为“本不需要……”；could have done表示本来能够做某事而实际上没有做，意为“本可以……”；must have done表示过去肯定做了某事，是对过去发生事情的肯定推测，意为“一定……”。根据“酒吧里的那个男人举止好奇怪”可知，这里表示对过去的肯定推测，应用must have done的形式。故选D。
10.I earn only 100 dollars a month, ______you earn 400 dollars.(A)
A. while
B. when
C. as
D. though
解析：根据句意可知，逗号前后部分表示对比关系，所以从句应用while(然而)引导。when：当……时；as：虽然，当……时；though：尽管。故选A。
11.Bob, Dick and Tom are 6,8, and 10 years old______.(A)
A. respectively
B. respectably
C. respected
D. respectfully
解析：respectively：分别，各自；respectably：体面地，可敬地；respected是动词respect的过去分词，可以作形容词，表示“受尊敬的”；respectfully：恭敬地，有礼貌地。根据句意可知，选A。
12.Children who are over-protected by their parents may become______.(B)
A
