大学英语：定语从句专项训练(七)

【考题】

19、The man showed us so heavy a stone ________ no man can lift.

A. that B. as

C. which D. and

20、 He stayed there for quite a long time, during ________ time he learned much spoken English.

A. that B. this

C. which D. same

【解析】

19、B.

当先行词前有so时，用as引导定语从句，as在从句中作主语或宾语。假若在lift后加上it，答案便是that了，请想想这是为什么。

20、C.

因前后均的句子，必需要选连词，排除B和D;又因在介词后不能用that来引导定语从句，所以选C。during which time在那段时间里。
