1.I have many books,some of __ are on chemistry.
A them B that C which D those
A和C项怎么辨析
2.-DO you have any idea what Paul does all day?
-As I know,he spends at least as much time playing as he __.
A writes B does writing C is writing D does write
选什么和为什么

1 C 首先要明确一个句子里不可能有两个谓语动词,但可以把一个动词变成从句,非谓语动词等形式这个句子已经有了一个动词have,也可以判断出是主句,由于后面是逗号,说明这个句子还没完,又出现了一个动词are,那么就只好变成从句的形式了,which引导非限定性定语从句,符合语法规则.填them不可以,如果填them,后面的也是主句了,因为它有完整的主语和谓语.
2 B spend sometime doing sth ,as as 并列相同的成分,does不一定都是助动词,它还可以做代词,即代替上文中的spend,这是英文中的避免重复,就像回答一般疑问句的时候要说yes,I do或yes,I am.因为spend是实义动词,所以用do来代替,由于是第三人称现在时,所以用does来代替
