练习3 主谓一致
一、单项选择
从每小题所给的A、B、C、D四个选项中选出一个可以填入空白处的最佳选。
1.The newly-published novel is so popular that more than one copy sold out.
A.have been
B.has been
C.have
D.are
【答案】B
【详解】考查时态和主谓一致。句意:新出版的小说太受欢迎了,以至于不止一份拷贝被卖光了。more than one+单数名词作主语时,尽管意义上看是复数,谓语动词仍要用单数,根据句意推断,sold out这一动作应该已经发生,应该用现在完成时下的被动语态。故选B项。
2.Over the past decade, the number of Monarch butterflies _____________ significantly.
A.has fallen
B.fell
C.is falling
D.have fallen
【答案】A
【详解】考查动词时态和主谓一致。句意:在过去的十年里,帝王蝶的数量显著下降。根据句中Over the past decade可知,句中的动作开始于过去,并持续到现在,应用现在完成时;the number of意为“……的数量”,后接可数名词复数,作主语时,谓语动词用单数,助动词应用has。故选A项。
3.Either the beautiful sights of this modern city or its local custom____ thousands of visitors during the past years.
A.have attracted
B.were attracting
C.has attracted
D.was attracting
【答案】C
【详解】考查现在完成时与主谓一致。句意:无论是这座现代化城市的美丽景色还是当地的风俗习惯在过去的这些年都已经吸引了成千上万的游客。由“during the past years”可知,这句话使用现在完成时。“either…or…”作主语时,谓语动词形式与or后主语保持一致,its local custom是第三人称单数,所以谓语动词也应使用第三人称单数形式。故选C。
【点睛】during the past+时间段, in the the past +时间段,in the recent +时间段都表示到现在为止的前一段时间,时态都用现在完成时。所以由本句话中的during the past years可知,这句话使用现在完成时。
4.— either he or I fit for the job?
—Neither he nor you .
A.Am; are
B.Is; are
C.Are; are
D.Is; is
【答案】B
【详解】考查主谓一致。句意:——他或者是我适合这个工作吗?——你们两个都不适合。并列连词either...or...和neither...nor...连接两个主语时,谓语动词遵循就近原则,第一句是疑问句,be动词靠近he,谓语动词用单数;后一句be动词靠近you,谓语动词应用are。故选B。
5.Among those presents _____ an iPad that his father gave him for his birthday.
A.have included
B.is included
C.has included
D.are included
【答案】B
【详解】考查主谓一致和被动语态。句意:在那些礼物当中有一个iPad,那是他爸爸送给他的生日礼物。分析句子可知,这是一个介宾短语放在句首的全部倒装句,正常句序应为 an iPad is included among those presents.真正的主语iPad 和动词include是被动关系,并且an iPad 是单数,应用一般现在时的被动结构,故选B项。
6.The evidence suggests that single fathers ____ more likely to work than single mothers.
A.should be
B.are
C.\
D.be
【答案】B
【详解】考查时态和主谓一致。句意:有证据表明,单亲父亲比单亲母亲更有可能去工作。此处suggest表示“表明”,后跟宾语从句不需要用虚拟语气,此处陈述客观事实,应用一般现在时,主语为fathers,谓语动词用复数。故选B。
7.Large quantities of money _________ spent on
