【解析】

【详解】

考查动词时态语态。句意:许多地铁站,包括我们学校附近的地铁站,目前正在建设中,以便有更便利的交通。此处表示动作正在进行,句中主语Many subway stations和动词construct是被动关系,所以此处用现在进行时的被动,与主语一致,故选B.

【点睛】

现在进行时的被动结构:be + being+过去分词

A number of Dongfeng trucks are being shipped abroad.一批东风卡车正被运往国外。

1)“be being done” 中的动词be应随主语作相应的变化。

2)将现在进行时的主动语态变为现在进行时的被动语态的关键是:把be doing变为be being done.

例1. The students are cleaning the classroom now. →The classroom is being cleaned now.

现在学生们正在打扫教室。 (are cleaning变为is being cleaned)

例2. The boy is counting some sheep. →Some sheep are being counted.

B.were treated

C.would treat

D.would be treated

20.You can’t move in right now. The house _____ now.

A.has painted B.is painted

C.is being painted D.is painting

【解析】

A.will be repaid B.was being repaid

C.has been repaid D.was repaid

【答案】A

【解析】

试题解析:考查时态辨析。根据句子末尾出现的时间状语later in life意为在以后的生活中,可以判断为将来时态,此处要注意的是不要被前文的now混淆,that you do now在句中充当the hard work的定语成分,与句子时态无关。故此处为将来时态。句意:不要担心,你现在付出的努力在以后一定会有所回报。故选A。

考点:考查时态辨析。

22.This kind of cloth_______well and large quantities of the cloth ________.

A.is sold; have been sold B.is sold; has been sold

C.sells; have been sold D.sells ; has been sold

【答案】C

【解析】

【详解】

23.(天津)Nowadays, cycling, along with jogging and swimming, ___________ as one of the best all-round forms of exercise.

A.regard B.is regarded

C.are regarded D.regards

【解析】

【详解】

考查被动语态和主谓一致。句意:现在骑自行车,慢跑和游泳被认为是最全面的锻炼方式之一。根据动词短语regard…as…“把……看作……”和句意确定应该用被动语态,排除A和D。再根据主语部分是由介词短语along with 连接的三个动名词做主语,应该谓语动词应该就前一致,即用单数,排除C,故选B。

【点睛】

本题考查方向涉及到动词的语态和主谓一致,首先要把握句意,判断主谓之间是主动还是被动关系,再者就是考查学生的考虑是否全面,即加之判断谓语动词的单复数,考查了学生对主谓一致中就前一致的把握。

24.After completing the training, I, together with my classmates, ____ to the town that was far from the city.

A.were sent B.was sent C.have been sent D.has been sent

【答案】B

【解析】

【详解】

考查时态和主谓一致。句意:完成了训练,我和我的同学被送往了远离城市的一个小镇。together with(和)符合就远原则,故现在只看主语I,是单数;根据下文的was判断为一般过去时,send和主语I之间是动宾关系,故用被动语态,即一般过去时的被动语态,主语是单数,故用was sent,故选B项。

【点睛】

本题考查就远原则,即谓语动词的形式和前面的那部分主语保持一致。常见的符合就远原则的词或短语有:as well as;(together/along/combined) with; rather than; except; besides; but; including; in addition to; apart from;instead of等

例如:

1. Nobody but two students is in the classroom.除了这两个学生,没有人在教室。

2. Everybody except you is down on me.除了你,大家都看不起我。

A.are to carry out B.are being carried out

C.were carried out D.will have been carried out

【答案】B

【解析】

【详解】

考查时态及语态。句意:新的能源共享项目正在全国数十个城市开展,目的是给中国未来几年的经济提供动力。根据语境可知,表示新的能源共享项目正在城市中开展实施,才能给中国的经济提供动力。要用现在进行时。New energy-sharing projects 与动词carry out是被动关系,因此要用现在进行时的被动语态。A. are to carry out一般将来时的被动,表示将实施,B. are being carried out一般现在时的被动,表示正在被实施,C. were carried out

表示动作发生在过去,一般过去时的被动;D. will have been carried out将来完成时的被动。故选B。

26.Amy, as well as her brothers, ________ a warm welcome when returning to the village last week.

A.is given B.are given

C.was given D.were given

【答案】C

【解析】

【分析】

【详解】

考查时态及语态。句意:十年前,当这家公司莫名其妙解雇许多员工时,收到了工会和社会正义团体的严厉谴责。该句有明显的时间状语a decade ago十年前,只能跟一般过去时连用。结合句意,这家公司是被谴责,所以要用被动语态。故选D项。

【点睛】

解时态题,可以结合句中的时间状语,选择相应的时态。至于语态,则根据句意来判断。比如该题有明显的时间状语a decade ago,这是典型的用一般过去时的标志,结合句意,这家公司是被谴责,所以必须要用被动语态,所以选择一般过去时的被动语态。

28.–The pine tree in front of the lecture hall is so tall.

–Yes. It ______ nearly 20 metres.

A.measures B.is measured C.will measure D.is measuring

【答案】A

【解析】

【详解】

考查动词时态及语态。句意:——演讲厅前面的松树好高啊。——是的。它近20米。measure此处意为“测量,量起来……”,为不及物动词,后接量的结果,不用于被动语态或进行时态。此处为描述客观事实用一般现在时,且主语为it,谓语动词需用第三人称单数形式。故选A。

29.Time magazine has chosen “The Guardians”,a group of journalists who____ for their work, as Person of the Year, for taking great risks in pursuit of greater truths.

A.will target B.have targeted

C.will be targeted D.have been targeted

A.the landmark decision was followed

B.was the landmark decision followed

C.did the landmark decision follow;

D.the landmark decision had been followed;

【答案】A

【解析】

【详解】

考察句子语序。句意:在这重大决议之后会出台一系列的办法来支持海南深化改革和扩大开放。In no time(立刻,马上)位于句首,句子用陈述语序,不用部分倒装。另外,该句陈述的过去的事情,因而用一般过去时,综述选A。

【点睛】

关于部分倒装。部分倒装,也叫不完全倒装,指的是谓语部分的be动词,情态动词或助动词放在主语之前的结构。常见的部分倒装分以下几类:第一,否定性副词或者赋词短语,比如seldom,hardly,at no time, in no case, on no occasion等位于句首时,比如,Hardly does he get late. 第二,only修饰副词性短语谓语句首时,比如only in this way can we succeed.而本题中in no time (立刻,马上),不是否定意义的短语,故不用部分倒装。
