一、选择题1．We hope that more trees________in our city next year.A．plant B．were plantedC．planted D．will be planted D解析：D【解析】【详解】句意：我们希望明年我们的城市能种更多的树。
考查动词的时态和语态。
主语more trees和动词plant是被动关系。
根据时间状语“next year”可知我们希望明年我们的城市能种更多的树，讲述的将来的动作，是要用一般将来时的被动语态，其构成为will be done。
故选D。
【点睛】句子的谓语动词不仅要考虑时态，也要考虑语态。
根据时间状语可以判断出时间是现在、过去或是将来；根据主语与谓语动词的关系可以判断出是主动还是被动。
此句“next year”是一般将来时的标志，树与种植是被动关系，综合起来是一般将来时的被动语态，所以答案为will be done。
2．Nick a job in a bank, but to our surprise, he didn't take it.A．is offered B．offered C．was offered D．has offered C解析：C【解析】【详解】句意：银行提供给尼克一份工作，但是出人意料的是，他没有接受。
考查被动语态和时态。
offer“提供”。
A.is offered现在时的被动语态；B.offered过去式；C. was offered过去式的被动语态；D.has offered现在完成时。
offer与主语Nick之间是被动关系，故用被动语态，根据下半句didn’t可知是过去式。
故选C。

根据句意，可知此处表示“生产”，故选C。
4．When Tim ________ why he was late for school, he just kept silent.A．was asked B．askedC．was asking D．is asked A【解析】【分析】【详解】试题分析：考查一般过去时的被动语态用法。
句意：当Tim被问到为什么上学迟到的时候，他只是保持沉默。
主语和ask之间是被动关系，所以用被动语态；分析句子，可由主句知道，本句的事情发生在过去，故从句要用一般过去时。
根据句意，故选A。
5．This special pen _________ for writing large size words.A．use B．uses C．is using D．is uesd D解析：D【解析】【详解】句意：这种特殊的笔是用来写大字的。
考查被动语态。
use使用；原形；uses使用，第三人称单数；is using正在使用，现在进行时； is uesd被使用，一般现在时态被动语态。
主语是This special pen可知用一般现在时态的被动语态，短语be used for…被用来做……。
根据题意，故选D。
6．A new zoo in our town center next month. I think it will be a good place for the teenagers to see the animals.A．build B．will build C．will be built C解析：C【解析】【详解】句意：下个月我们市中心将建一个新动物园。
我想这对青少年来说是个看动物的好地方。
考查动词时态。
build建造，原形； will build将建造，一般将来时；will be built将被建造，这里是一般将来时的被动语态。
根据“next month.”可知用一般将来时，主语是“A new zoo”可知，这里是一般将来时的被动语态，其结构是will be done的形式。
根据题意，故选C。
7．I won't leave my office until my work___________.A．finishes B．will finish C．is finished D．finishing C解析：C【解析】【详解】句意：我直到完成工作才会离开办公室。
本题考查时态和语态。
finishes是一般现在时，will finish是一般将来时，is finished是一般现在时的被动形式；finishing是现在分词或动名词。
until引导的时间状语从句用一般现在时，主语my work与谓语finish之间是被动关系，用被动语态。
故选C。
8．Lots of flowers and trees on both sides of the streets every year.A．were planted B．are planted C．are planting D．were planting B解析：B【解析】句意：街道两旁每年都种上许多花和树。
考查被动语态辨析。
were planted 一般过去时的被动语态；are planted 一般现在时的被动语态；are planting 现在进行时；were planting 过去进行时。
根据时间状语every year，句子用一般现在时，排除A和D选项。
主语flowers和trees和谓语plant之间是被动关系，所以用一般现在时的被动语态are planted。
故选B。
9．I don’t think teenagers should to go to net bars.A．allow B．be allowing C．allowed D．be allowed D解析：D【解析】【详解】句意：我认为不应该允许青少年去网吧。

allow 动词原形；be allowing 现在进行时；allowed 一般过去时；be allowed 一般现在时的被动语态。
should是情态动词，后接动词原形。
主语teenager与动词allow之间是被动关系，所以用被动语态be done的结构，所以空格处填be allowed。
故选D。
10．—Where did you go last night?—I to go to Li Lei’s birthday party.A．asked B．am asked C．have been asked D．was asked D解析：D【解析】试题分析：通过上句的last night可知，本句应该是过去时，故排除BC；根据句意可知，“我”应该是被邀请参加李雷的生日晚会的，要用被动语态，所以本题选D。
考点：本题考查时态和语态。
点评：完成本题时，首先应注意时态，然后确定语态问题。
另外注意be asked to do sth.表示“被要求做某事”。
11．This book_______by a lot of young people today.A．reads B．are reading C．is read C解析：C【解析】【详解】句意：今天很多年轻人都读这本书。
考查一般现在时的被动语态。
reads一般现在时；are reading现在进行时；is read一般现在时的被动语态。
根据句意可知此句时态是一般现在时的被动语态，其构成is/are done+其他+by+主语；又因为主语为the book ,故谓语动词用第三人称单数。
故选C。
12．Young trees ________ every year to keep the sand away from the city and make the environment better and better.A．were planted B．have planted C．will plant D．are planted D解析：D【详解】句意：每年都要种上小树，使城市远离沙尘，使环境越来越好。
本题考查被动语态。
Plant意为“种植”。

13．—Do you think the old machine is ____________， grandma?—Yes, it is _________for carrying water.A．use; using B．useful; used C．use; used D．useful; use B解析：B【解析】【详解】句意：—你认为这个旧机器有用吗，奶奶？—是的，它被用于取水。
using是动名词；use是动词原形；used是过去分词，构成被动语态；useful有用的，是形容词作表语，所以第一空用useful；短语be used for被用于做某事，第二空用used。
故选B。
14．—I won’t go to the party unless Sue __________ , too.—You mean if Sue comes you’ll come?A．will invite B．invites C．invited D．is invited D解析：D【解析】【分析】【详解】--除非苏被邀请了不然我不会去参加聚会。
