() 4. He didn’t make clear when and where the meeting would be held.

A.this
B.that
C.it
D.these

C

本题考查it作形式宾语的用法。在“make it + 相关结构 + 宾语从句”的句式中，it用作形式宾语，真正的宾语是后面由when and where引导的从句，以此避免句子头重脚轻。选项A、B、D均不能充当形式宾语，故正确答案为C。

() 5. I tried to tell you, but you were always busy to or listen.

A.too; talking
B.too; to talk
C.enough; to talk
D.so; to talk

B

本题考查固定结构“too...to...”的用法，意为“太……而不能……”，其中“to”后接动词原形。分析选项：A选项中“talking”是动名词形式，不符合“too...to...”的结构要求；C选项中“enough”修饰形容词时应放在形容词之后，即“busy enough”，此处位置错误；D选项中“so”常与“that”构成“so...that...”结构（意为“如此……以至于……”），后接从句，不符合本题句式；B选项“too; to talk”符合“too busy to do sth”的结构，且“or”连接并列的动词原形“talk”和“listen”，语法正确。

() 6. — All of us think dangerous for girls to stay out late.
— Yes. It’s important them to be safe all the time.

A.it is; of
B.it; for
C.that is; of
D.that; for

B

本题考查it作形式宾语和固定句型的用法。
1. 第一空：“think it + 形容词 + for sb. to do sth.”是固定结构，it在句中作形式宾语，真正的宾语是后面的动词不定式短语“to stay out late”，因此此处应填it。
2. 第二空：“It's + adj. + for sb. to do sth.”是固定句型，意为“对某人来说做某事是……的”。当形容词描述事物的性质（如important）时，用介词for；若形容词描述人的品质则用of。此处important描述的是“时刻保持安全”这件事的性质，所以用for。结合选项，正确答案为B。

() 7. It is wrong of a student his homework by himself.

A.to do
B.don’t do
C.not do
D.not to do

D

本题考查固定句型“It is + adj. + of sb. + (not) to do sth.”，该句型用来表示“某人（不）做某事是……的”。结合句意“学生不自己做作业是不对的”，此处需要用否定形式的不定式，即“not to do”。选项A为肯定不定式，不符合句意；B、C的形式不符合该固定句型的结构，均排除。因此正确答案是D。

() 8. Many changes in my hometown in the past few years.

A.took place
B.were taken place
C.have taken place
D.have been taken place

C

take place是不及物动词短语，没有被动语态，因此可排除B、D选项；时间状语"in the past few years"是现在完成时的标志性短语，现在完成时的结构为“have/has+过去分词”，主语"Many changes"为复数，故用have taken place，应选C。

() 9. The villagers expect that the building of the bridge before the rainy season comes.

A.is completed
B.will complete
C.completes
D.will be completed

D

本题考查一般将来时的被动语态。首先，宾语从句的主语the building of the bridge与动词complete之间是被动关系，桥的建造是被完成，因此需用被动语态，排除主动语态的B、C选项；再根据时间状语before the rainy season comes可知，动作发生在将来，要用一般将来时的被动语态“will be + 过去分词”的结构，故答案选D。

() 10. The United Nations has done a lot for the peace of the world since it in 1945.

A.sets up
B.set up
C.is set up
D.was set up

D

本题考查一般过去时的被动语态。since引导时间状语从句时，主句用现在完成时，从句需用一般过去时；且“the United Nations（联合国）”是被建立的对象，要用被动语态。一般过去时的被动语态结构为“was/were + 动词过去分词”，主语为单数，set的过去分词为set，故应选was set up。

() 11. — the charity show organized? — We organize it once a year.

A.When is
B.How often does
C.When does
D.How often is

D

根据答语“once a year（一年一次）”可知，问句是对频率提问，应用疑问词组How often，排除A、C选项；句子主语the charity show与谓语动词organize是被动关系，需用被动语态（be+过去分词），被动语态的一般现在时结构为“am/is/are+过去分词”，因此此处要用How often is，排除B选项。

() 12. — What happened to Mrs Lee?
— She was badly hurt in the traffic accident. Luckily, she in time.

A.operated on
B.was operated
C.was operated on
D.was operating

C

本题考查被动语态的用法。operate on sb. 意为“给某人做手术”，主语she是动作的承受者，应用被动语态，其结构为“be+动词过去分词”，且短语中的介词on不能省略。A选项为主动语态，不符合语境；B选项缺少介词on，结构错误；D选项为过去进行时主动形式，不符合题意。C选项“was operated on”是正确的被动结构，符合语境。

() 13. The books well.Make sure to get one before they out.

A.are sold; are sold
B.sell; sell
C.sell; are sold
D.sell; sell

C

本题考查sell的特殊用法和被动语态。1. 当表示某物的销售状况时，常用主动形式表被动含义，“The books sell well”意为“这些书卖得好”，第一空用sell；2. “sell out”表示“卖完”，此处books是被卖完的对象，要用被动语态“are sold out”，所以第二空填are sold。结合选项，选C。

() 14. — It’s time to do your homework, Jack.
— Yes, Mum. I’ll turn off the TV as soon as the football match .

A.ends
B.is ended
C.will be ended
D.will end

A

本题考查as soon as引导的时间状语从句的时态用法，遵循“主将从现”原则，即主句用一般将来时，从句需用一般现在时表将来。且the football match与end是主动关系，无需使用被动语态。选项中只有A选项ends为一般现在时主动形式，符合语法规则；B为一般现在时被动语态，C为一般将来时被动语态，D为一般将来时，均不符合要求。

() 15. — Mum, when can I go and play football?
— Not until your homework .

A.finishes
B.will finish
C.is finished
D.will be finished

C

本题考查被动语态与时间状语从句的时态用法。首先，homework和finish存在被动关系，作业是被完成的，因此需用被动语态，可排除主动语态的A、B选项；其次，在until引导的时间状语从句中，遵循“主将从现”原则，主句表将来含义时，从句用一般现在时表将来，故此处用一般现在时的被动语态is finished，答案选C。

() 16. — Have you finished your history project yet?
— Not yet. I’ll finish it if I ten more minutes.

A.give
B.am given
C.will give
D.will be given

B

本题考查if引导的条件状语从句的时态规则和被动语态的用法。1. if引导条件状语从句时，遵循“主将从现”原则，主句用一般将来时（I’ll finish it），从句需用一般现在时，因此排除选项C、D；2. 从句主语I与动词give是被动关系（“我被给予十分钟”），要用一般现在时的被动语态，结构为“am/is/are + 动词过去分词”，主语I对应的be动词是am，give的过去分词是given，所以选am given。

() 17. These new types of energy from the sun, wind and water . Moreover, they produce little pollution.

A.will never be run out
B.are going to be run out
C.will never run out
D.are going to run out

C

本题考查动词短语run out的用法。run out是不及物动词短语，主语为物时不能用于被动语态，因此排除A、B选项；结合语境“这些新能源几乎不产生污染”可知，此处表达“永远不会耗尽”，C选项符合语义，D选项“将要耗尽”不符合语境，故选C。

() 18. In most kitchens, sharp knives prepare food, such as cutting vegetables and meat.

A.used to
B.are used to
C.are used for
D.get used to

B

本题考查use的相关短语辨析。A选项used to do sth. 表示“过去常常做某事”；B选项are used to do sth. 为被动语态结构，意为“被用来做某事”；C选项are used for后接动名词形式，意为“被用来做某事”；D选项get used to doing sth. 表示“习惯于做某事”。根据空格后是动词原形prepare，结合句意“在大多数厨房里，锋利的刀被用来准备食物，比如切蔬菜和肉”，此处需用被动语态表达“被用来”的含义，故选B。

() 19. In good manners, when someone invites you to dinner, the bill by the person who made the invitation, not by the guests.

A.is paid for
B.pays for
C.was paid for
D.will pay for

A

本题考查一般现在时的被动语态。句子描述的是礼貌礼仪中的常规规则，需用一般现在时；且“the bill”与“pay for”之间为被动关系，账单是被支付的对象，所以要用被动语态，结构为“am/is/are + 过去分词”。B、D选项为主动语态，不符合逻辑；C选项是一般过去时的被动语态，时态与语境不符，故正确答案为A。

() 20. Many charities in our city to help poor children, and they offer them education and daily necessities.

A.are founded; aim at
B.found; aim to
C.are founded; aim to
D.found; aim at

C

第一空，主语Many charities与动词found是被动关系，需用一般现在时的被动语态are founded，排除B、D选项；第二空，aim to do sth是固定搭配，后接动词原形，符合空后offer的形式，而aim at后接动名词或名词，故选C。
