选择题的理由

Answer 1

1.定语从句关系代词（that which who）,关系副词（when where why）引导的是从句，或者从意思上来看，定于从句都要有一个先行词（可以是具体的名词，如2句中的the bus 或者是代词,如5句中的all，修饰先行词的句子是从句）

2.B 把从句还原：Most of the bus因为用which 替代了the bus 所以选most of which

3.B 先行词是people,从句是who ()cars 从句中who 替代了people 所以还原回去就是People()cars ，所以动词用复数。但如果抛去定从不看，这句话为The number of the people()increasing.主语是the number 是一个数，所以动词应用单数

5.这句也牵扯到了不能把定从与主句混淆的问题。先行词是all,定于从句是that can be eaten ，除去定于从句，这句话的主干应是all ()eaten up.谓语动词是done的形式所以选完成时，all 此处应该是复数，所以选D

有什么不懂的可以再问我

1、定语从句是由关系代词或关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句，一般紧跟在它所修饰的先行词后面。 在复合句中充当主语的句子叫做主语从句.
