主谓一致
The number of medical schools reached 18 in the early 1990s and ________ around that level ever since.
are remaining B. has remained
C. have remained D. is remaining
答案:B
解析:根据句意和时间ever since可知这里表示从那时到现在一直保持的状态,用现在完成时。主语是The number of谓语用三单。故选:B。
The musician along with his band members ___________ ten performances in the last three months.
gives B. has given
C. have given D. give
答案:B
解析:考查现在完成时与主谓一致。句意:在过去的三个月里,这名音乐家与他的乐队成员已经完成了十场演出。由“in the last three months”可知,这句话的时态为现在完成时,故排除AD选项。本句主语为the musician,为第三人称单数形式,句中的“along with his band members”是附加成分,故谓语动词要用第三人称单数形式。故选B。
Amy, as well as her brothers, ____________ a warm welcome when returning to the village last week.
is given B. are given
C. was given D. were given
答案:C
解析:本题考查时态和语态。句意:艾米和他的兄弟们当上周回到村里时,受到了热烈的欢迎。根据last week可知应用过去时,排除选项A和B。as well as连接并列主语,谓语动词就前原则。这句话真正的主语是Amy,她受到热烈欢迎,所以用过去时的被动。故选C。
