27、e country that she was.,8.主句以there be 开头时,There is little that I can do to make up for the lost time.,不用that的场合如下：1）非限制性定语从句中:是对所修饰的成分作进一步说明，通常和主句间用逗号隔开，将从句拿掉后其他部分仍可成立 Last night,I saw a very good film,which was about the Long March.,2）介词放在关系代词之前时 This is the man from whom I learnt the news,3）句中出现了t

28、hat，或先行词是that时 I have found that which I was looking for.,二、只用who的情况,One _ has nothing to fear dares to tell the truth.The ones _ laugh at the disabled are not good students.Anyone _ fails to finish the task should be punished.Those _ want to go to The Great Wall sigh up here.,who,who,who,who,先行词是on

30、one we visited that year?Is this the school that we visited that year?,He is one of the students who are from the south.He is the(only)one of the students who is from the south.,限制性定语从句,限制性定语从句用来修饰和限制先行词，与先行词的关系非常密切，它所修饰的先行词代表一个（些）或一类特写的人或物，说明先行词的性质，身份，特征等状况。如果去掉，则意思含混不清。,A doctor is a person who lo

31、oks after peoples health.上边的例句如果去掉who looks after peoples health.就成了A doctor is a person(医生是人)，完全失去了原句的意义。,非限制性定语从句,非限制性定语从句起补充附带说明作用，去掉也不会影响对全句的理解，在非限制性定语从句的前面往往有逗号隔开，如若将非限制性定语从句放在句子中间，其前后都需要用逗号隔开。,Yesterday Jimmy left for Canada,where he had stayed two years.昨天，吉米动身到加拿大去了，他曾在那儿呆了两年。Toms father,who

32、 is over sixty,still works hard day and night.汤姆的父亲已经六十多岁了，但他仍然从早到晚辛勤的工作。,引导非限制性定语从句的关系代词如下表所示：指代对象 指代人 指代物主格 who which,as宾格 whom which,as所有格 of whom,whose（指代人）which,of which,whose（指代物）,注意：关系代词that 不引导非限制性定语从句。关系副词why 不能引导非限制性定语从句 引导非限制性定语从句的关系副词主要有when,where,She said she had finished her work,which I doubted very much.她说她已经完成了这项工作，我对此深表怀疑。As most people know,Fujian is famous for tea.周所周知，福建以茶出名。,
