The man (that) my father saw on the street is my teacher. ★关系代词which指物，不指人，在从句中作主语或宾语。作主语时，which不可省略；作宾语时，which可以省略。例如： It’s a book which introduces how to cook. The bike (which) Jim’s father bought yesterday is a present for Jim. ★关系代词who只可指人，在从句中作主语，口语中也可作宾语。作主语时，who不可省略；作宾语时，who可以省略。例如： This is the man who found my handbag. The girl (who) I met at the party yesterday is Jim’s sister. 【拓展】 ★当指物的关系代词在介词后作介词的宾语时，只能用which，且不能省略；当介词不在关系代词前面时，可以用that或which，它们可以省略。例如： This is the house in which my grandparents lived 30 years ago. This is the house (that / which) my grandparents lived in 30 years ago. ★当先行词既有人又有物时，关系代词只能用that；当先行词是不定代词时，关系代词一般用that；当先行词被形容词最高级，序数词以及only等词修饰时，关系代词常用that。例如： Mike took many photos of the buildings and the people that he was fond of. That’s all that I can do for you. She is the youngest writer that I have ever known. Mount Tai is the first place that I want to visit. Tony is the only student that made a speech at the opening of the sports meeting. 精选精练 一、单项选择 1．We all miss Wu Mengchao _______ saved many lives in his medical work.
