1．Exactly________the potato was introduced into Europe is uncertain, but it was probably around 1565.
答案 when [句意：马铃薯具体是在什么时候被引入欧洲的并不确定，但有可能是在1565年左右。由句意可知，后一分句是来补充说明前一分句中的不确定的内容的，根据“around 1565”可知是对时间进行提问，因此用when引导前面的主语从句。]
2．I think________impresses me about his painting is the colours he uses.
答案 what [句意：我认为他的画给我印象最深的是他对色彩的运用。what引导主语从句，且在从句中作主语，表示“……的”。]

答案 what/whatever [句意：一些人认为，不管是以前发生的还是现在发生的事情都会在将来重现。此处“________has happened before or is happening now”是主语从句，且从句中缺少主语，故填what/whatever。]

答案 that [句意：我突然想起我没锁门。it是形式主语，真正的主语是that引导的从句。It occurs to sb. that意为“某人突然想起……”。]

3．It struck me most in the movie was the father's deep love for his son.
________________________________________________________
答案 It→What [句意：这部电影最打动我的是父亲对他儿子深深的爱。“It struck me most in the movie”为主语从句，从句中缺少主语，表示“所……的”，故用What，It不引导从句。]

________________________________________________________
答案 Which→Whichever [句意：你们中任何一个人打破窗户都必须赔偿。根据题干中one of you可知，空处要用whichever修饰one, 指“你们中的任何一个人”。which指哪一个，表达疑问，故改为whichever。]

________________________________________________________
答案 that→what [句意：你失败多少次都不要紧；要紧的是你有多少次站起来并再次尝试。分析句子成分可知，“that matters”是主语从句，从句中缺少主语，指物，故用what引导。that不作成分。]

7．It was never clear that the man hadn't reported the accident sooner.
________________________________________________________
答案 that→why [句意：不清楚这个人为什么不早一点报告那起事故。此处需要连接副词引导主语从句并在从句中作原因状语，why表示“为什么……”。故把that改为why。]
8．—The manager finally agreed to our new marketing proposals.
—It never occurred to me what you could succeed in persuading him to change his mind.
________________________________________________________
答案 what→that [答句表示“我根本就没想到你能说服他改变自己的看法”，句中It作形式主语，这里应该用that引导主语从句，连接词在从句中不作任何成份，也无意义。故把what改为that。]
