2020广东专插本英语：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，答案就是that了，请想想这是为什么。

　　20、C.

　　因前后均的句子，必须要选连词，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。
