　　语法知识点：
　　1. which 引导的非限制性定语从句：在形式上，从句与被修饰的名词之间必须用逗号隔开;在意义上，从句只是意义上的进一步补充和说明，并不影响被修饰名词的性质界定。缺少该从句，先行词依然性质确定。例句：
　　The building still stands in the earthquake, which was built 10 years ago. 那幢大楼是去年建立的，在地震中仍然矗立着。
　　2. it 作形式宾语，由 that 引导的从句充当真正宾语：和it 作形式主语一样, 我们常用 it 来作形式宾语, 把真正的宾语从句放在句末。例句：
　　He has made it clear that he will not give in. 他表明他不会屈服。
　　3. demand等动词后宾语的虚拟：从句中使用 (should)+动原。例句：
　　He demands that we should get rid of the bad habits. 他要求我们摒弃这些不良习惯。
　　4. whether 引导的表语从句。 例句：
　　The question is whether we need to add more computers. 问题是我们是否需添加更多地电脑。
　　5. it 作形式主语, whether 引导的主语从句。 例句：
　　It is still a mystery whether he will come to join us. 他是否会加入我们仍然是个谜。
