---Yes, that’s right. I’ll first.

A. too much, look them up

B. too many, look up them

C. much too, look them up

D. too many, look them up

答案：

A. too much, look them up

B. too many, look up them

C. much too, look them up

(答案→)D. too many, look them up

解析：本题的含义是你认为在这一单元有许多新单词吗？首先我要查询这些单词所表示的意思，too many修饰可数名词复数，表示太多的意思，look sth up表示查询的意思，sth为代词时必须要位于look和up之间，故本题选D。
