1.There is no doubt ________ Catherine is fond of dancing, for she always
practices it on weekends.
A. whether B. if C. that D. which
【答案】C。解析:考查同位语从句,句意:毫无疑问Catherine喜欢跳舞,因为她总是在周末练舞。分析句子的结构可知,逗号之后为“for”引导的原因状语从句,逗号之前是主句,主句中结构为"There is no doubt that…"意为"毫无疑问…",连词"that"引导同位语从句解释说明名词"doubt"的具体内容,同位语从句中句子结构和意思已完整,"that"无意义也不充当成分,只起连接词的作用.故C为正确答案。
2.You have seen the girl ________ sister is a Chinese teacher.
A. whom B. of whom C. whose D. of which

3.He found it increasingly difficult to read, ______ his eyesight was beginning to fail.

5.The crazy fans ________ patiently for two hours and they would wait till the movie star arrived。
A.were waiting B.had been waiting C.had waited D.would wait
