参考答案：1. 当主语被分数或百分数修饰时，谓语和后面的名词一致，第一空One-third of +单数名词+单数谓语，第二空seventy percent of +复数名词+复数谓语，句意：三分之一的地区被绿树覆盖。

已经种植了大约百分之七十的树木选B 2. the number of“的数量”，作主语时，谓语动词常用单数，而“a number of+复数名词”意思是“大量的；许多”，作主语时，谓语动词用复数形式 3. population 是人口,人口不可数,是第三人称单数,应该用is;One third of it 是指三分之一的人,人是可数名词,有复数,用are.

4. 英语中由Not only……but also 连接的两个主语，谓语动词与后一个主语保持一致，we 是复数形式，故系动词用are，下文as well as we 引到伴随主语，实际主语是he，故系动词用单数，选C。

5. what 引导的名词性从句作主语时，谓语动词常用单数形式但当作表语的名词为复数，或what 从句是一个具有复数意义的并列结构时，谓语动词常用复数形式,如：What I say and think are no business of yours. 。

6. 在“one of +复数名词+定语从句”的结构中，定语从句中谓语动词常用复数；在“the （only）one of +复数名词+定语从句”的结构中，定语从句中谓语动词常用单数 7. 就近原则 8. “many a +单数名词，more than one+单数名词”作主语，尽管从意义上看是复数，但谓语常用单数形式。

9. 前面一句话表示一个刀子和一个叉子，是两件东西，谓语动词用复数；后面一句话表示一副刀叉，谓语动词用单数 10. 第一句中的her family 应理解为“她的家庭”；第二句中的her family 应理解为“她一家人”。
