Unit 5 theme parks Grammar课时作业

Ⅰ.单项填空

1．With fewer and fewer farmers________ chickens，the price of eggs in the market________.

A．rising；rises B．raising；raises

C．rising；raises D．raising；rises

答案　D

解析　句意为：由于越来越少的农民养鸡，因此市场上鸡蛋的价格增长了。第一空考查"with＋宾语＋宾语补足语"结构，farmer与raise之间是主动关系，故用v.­ing形式作宾语补足语。第二空应填不及物动词，表示"上升"，故选D项。

2．Violent programs on television may have a bad________ on children.

A．affection B．pressure

C．influence D．control

答案　C

解析　句意为：电视上的暴力节目可能对儿童有不良的影响。have a(n)．..influence/effect on"对......有......影响"为常用词组。

3．There are some health problems that，when ________ in time，can become bigger ones later on.(2013·浙江，19)

A．not treated B．not being treated

C．not to be treated D．not having been treated

答案　A

解析　句意为：有些健康问题，如果不及时处理，以后会变得更严重。when not treated in time为插入语，在本句中为时间状语从句，把that can become bigger ones later on这个定语从句给隔开了。when引导时间状语从句时，可以出现省略的现象，但必须满足两个条件：首先，时间状语从句中的主语必须和主句主语一致；其次，从句中含有be动词。本句中补充完整的状语从句为：when they are not treated in time，其他选项形式不对。故答案为A项。

4．-Lily is sure to win the oral English contest.

-I doubt ________she will make it.

A．that B．whether

C．how D．why

答案　B

解析　doubt作"怀疑"解，用于肯定句时，其后的宾语从句常用whether或if引导。
