Unit 4 earthquakes grammar 课时作业

　　Ⅰ.单句语法填空

　　1．Mary is very proud because her father is an astronaut.

　　解析：考查冠词。句意：Mary很自豪，因为她爸爸是宇航员。astronaut是可数名词，且发音以元音音素开头，所以用an。

　　2．They don't allow parking(park) in front of the office.

　　解析：考查非谓语动词。句意：他们不允许在办公室前停车。allow doing sth.允许做某事，为固定用法。

　　3．How we can raise enough money for the project remains to_be_discussed(discuss)．

　　解析：考查非谓语动词。句意：我们怎么才能为该项目筹到足够的钱有待讨论。分析句子结构可知，discuss和主语之间是逻辑上的动宾关系，且根据句意可知，discuss这一动作将要发生，所以用不定式的被动式。

　　6．It is uncertain what side effects the medicine will bring about.

　　解析：考查主语从句。句意：这种药物会带来什么样的副作用还不确定。分析句子结构可知，空处引导主语从句，从句中缺少定语，表示"什么"，后面可以直接跟名词，故用what。

　　7．What I want to tell you is the deep love and respect I have for you.

　　解析：考查主语从句。句意：我想告诉你的是我对你深深的爱和尊敬。分析句子结构可知，空处引导主语从句，且从句中缺少宾语，指事物，故填What。
