名词前面有"the" 不会影响引导词,也就是说不一定要用"THAT" 在定语从句中,只能用THAT引导的有下列几种情况: 1,当名词前面有不定代词" all/anything/something/nothing..."修饰,或先行词就是这些不定代词,只能用"that" 引导. EG:This is all that I can do for you. 2.当名词前有序数词,形容词最高级修饰时,只能用" that" 引导. EG:It is one of the most interesting stories that I have heard so far. 3.名词前面有the only,the very,the last.一般只用"that" Here is the only pencil that I have in hand. 4.被修饰的名词既包含人也包含物的话,也只用"that" The readers are attracted by the scientist and his achievements that were reported in the newspaper. 5.前面已经出现过"which",为避免重复,而使用"that" Which is the bus that we are going to take?
