Unit 1 Cultural Relics reading课时作业

Ⅰ.单项填空

1. I don't believe we've met before，________I must say you do look familiar.

　　A．therefore B．although

　　C．since D．unless

答案 B [考查状语从句。句意：尽管我必须说你的确看起来面熟，但我认为我们没见过面。此处为让步状语从句，故用although引导。]

2．After five hours on your feet，you ________a break.

A．conserve B．deserve

C．observe D．reserve

答案　B　[conserve保存；deserve值得；应该；observe观察；遵守；reserve

保留。由句意"站了五个小时后，你应该休息一下。"可知，B项正确。]

3．The reason________he told me________he was late is an excuse.

　　A．why；that B．that；why

　　C．which；that D．that；which

答案 B [解析：句意：他告诉我的为什么他会迟到的原因完全是个借口。本句的主干是：the reason is an excuse。其中的he told me是定语从句，省略了在定语从句中作宾语的引导词which或that；其中的he was late也是定语从句，也修饰先行词the reason。引导词可以用that，for which，why或者不填，在定语从句中作原因状语。]

4．-I have heard that John wrote a long letter to the president.

-His uncle insisted that he ________it.

A．did B．had done

C．do D．would do

答案　C　[句中的insist意为"坚持要求"之意，因此宾语从句应用虚拟语气

形式，故C为正确答案。]

5．The growing speed of a plant is influenced by a number of factors，________are

beyond our control.
