A.most people have worked B.have most people worked
C.most people had worked D.had most people worked
【答案】B
【解析】

试题分析:“由于那天晚上被要求加班,我错过了一场精彩的电影”,主语“我”和动词ask之间是动宾关系,要用过去分词,“被要求加班”这一动作发生在动作missed之前,要用过去分词的完成式having been asked,A项正确;B项to ask是动词不定式,表示目的或将要发生的动作,不正确;C项having asked是现在分词的完成式,不正确;D项to be asked是动词不定式的被动形式,不符合语境,故选A。
C.have been treated D.had been treated
【答案】C
【解析】
【详解】
考查时态语态。句意:由于被污染了的环境和人们糟糕的生活方式,越来越多的癌症病人正在医院里接受治疗。本句主语more and more cancer patients与动词treat构成被动关系,要使用被动语态;而且很多病人接受治疗是已经发生的事情,要用完成时表示,所以本句使用现在完成时的被动语态,故选择C项。
【点睛】
1.Since自从---以来(可做介词和连词),和现在完成时态连用。
He has lived here since he came.自从他来到这里,就一直在这里住着。
2.It is /has been+一段时间+since主语+一般过去时态+其他。自从做某事有多长时间了。
在这个句型中如果从句的动作是终止性动词,则表示从动作开始到现在多长时间了;如果从句的动作是持续性动词,则表示从动作结束到现在多长时间了。It is three years since he joined (终止性动词)the army.他参军有三年了;It is five years since he lived(持续性动词)here.他离开这有五年了。
【点睛】
a huge amount of意为“大量的”,修饰不可数名词。本题中environmental damage为不可数名词,由a huge amount of修饰,a huge amount of environmental damage为主语表示单数,所以谓语动词要用单数。
12.— When will the bike-sharing schemes be introduced to the public?
8.We have done things we ought not to have done andundone things we ought to have done.
A.leaving B.left
C.will leave D.leave
【答案】B
【解析】
【详解】
考查现在完成时。句意:不该做的事我们都做了,留下该做的事都没做。句子主干是个并列句,即we have done things we ought not to have done和left undone things we ought to have done,所以have done和have left是并列谓语,其中have相同,省略,只不过两个并列句里分别含有一个定语从句,第一个分句中we ought not to have done作things的定语,第二个分句中we ought to have done作things的定语。故选B选项正确。

【点睛】
固定句式:It is/was the+序数词+that从句;句意:这是某人第几次做某事的时候了。如果前面是is,后面使用现在完成时;如果前面是was,后面使用过去完成时。(1)It is the first time that I have come to the Great Wall.这是我第一次到长城去。(2)It was the first time that he had visited the Great Wall.那是他第一次参观长城。
