回答：1_______,and we'll arrive in Hangzhou.A.Another hour B.An hour later.After an hour D.In an hour我选B，可答案是A，为什么呢？and 是个连词，不是代表一个句子吗？A项相当于一个句子:We are given an another hour,如果没有and,就可以用(If we are)given another hour,祈使句+ and+ 陈述句,是一个常用句型,前边省略后就剩下一个词或词组.再如: One more step, and we'll shoot.2 Once more I am in Shanghai,__________I have not been for yearA that B whereC which D when我选C，可答案是B，为何？前边先行词是指地点,后边的定语从句I have not been 中缺表语,相当于there,又没有选择的意义,所以选where.3，To their great joy,the day they looked forward to_________at last!A coming B had come C came D to come我选A 可答案是C “looked forward to”后不是加名词的吗？looked forward to的宾语是the day,这里却the day的谓语,they looked forward to_是定语从句, 修饰the day.所以要用c,came来做谓语.
