Ⅰ.单句语法填空
1．Due to ________(it) humor and irony (反语), xiangsheng has spread far and wide.
its [句意：由于具有幽默与讽刺的效果，相声广为流传。根据空后的“humor and irony”可知，空处应用形容词性物主代词。 ]
2．All in all, every student should behave ________(he) and keep away from violence.
himself [此处behave oneself为固定搭配，意为“举止得当”，此处需要用反身代词himself。]
3．The company and the effect ________ brought about did a great deal of good to our business in the market.
it [句意：这家公司及其所带来的影响对我们的业务有很大的好处。句中的it代指the company, it brought about为定语从句，先行词the effect作brought about的宾语，故省略了关系词which或that。]
4．It wasn't our idea, so don't blame ________ (we)．
us [动词blame后接宾格代词us作宾语。]
