They went to American three years ago ，since when they have lived there . ( when指代three years ago 。不能换为which ，因为which只能指代three years =and since then)(二) that在有些句型中可视为关系副词：

25、 1 . way后面的定语从句常用that或in which引导 , 但可省略。 e.g. I dont like the way ( that / in which ) you speak to your parents . The way ( in which / that ) he worked on the problem was wrong . 注： 如果way在从句中作主语或宾语, 应该用关系代词which / that。 e.g. He explained the problem in a way that / which everyone could accept . 2 .

26、It is ( about , high ) time that (正)是 的时候了。 that从句中常用一般过去时, that在口语中可省略。 e.g. It was high time that we stopped pollution .

28、itten by the writer . 2 . one of 前有the , the only ，the very ，the first时 , 从句谓语用单数。 e.g. Tom is the only / very one of the boys who knows the truth .(二) 定语从句的隔离现象： 1 . 定语从句和先行词之间有时会被状语, 定语或者其他成分隔开, 要注意找准先行词。e.g. The film brought the hours back to me when I was taken good care of in that village . Is

29、there a restaurant around where we can have lunch ? ( around adv. 在周围 )The days are gone when we used foreign oil . (主句谓语较短, 隔开先行词与定语从句)2 . 定语从句中关系代词和关系副词的后面有时会出现插入语。 e.g. 1) He is the man who I think is fit for the job . 2) - Is that the small town you often refer to ? - Right , just the one _ you

30、know I used to work for years . A . that B . which C . where D . what (三) 定语从句中有时会使用倒装语序：e.g. Three days later , we found an old house , in front of which stood a big tree .

31、。(最明显的区别是定语从句一定有先行词) e.g. After the war , a new school was put up where there had once been a theatre . (状语从句) A new school was put up at the place where there had once been a theatre . (定语从句) 2 . 区别“介词+which”的定语从句和“介词+what”的宾语从句。 e.g. 1) This is the company in which he worked three years ago . ( which 引导定语从句 ) 2) A modern city has been set up in _ was a wasteland ten years ago . ( what宾语从句) A . what B . which C . that D . where 3 . 区别that的定语从句和同位语从句。 e.g. The news that he won the match made us excited . ( 同位语从句 ) The news ( that ) he
