68、 engine你知道蒸汽机中存在热损耗的原因吗？2.我们也可以用for which 来替代 why。例如：The reason why for which you failed ， I think ， was that you had turned a deaf ear to your mother s advice我认为你失败的原因是你不听你母亲的忠告。注意： 在“the reason why sb does sth 从句 ” 的结构中， that 不能换成because 。定语从句错误分析初学定语从句时，同学们易犯的错误归纳起来有语义重复、主谓不一致及引导词的误用等。同学们可以先试着找出下

70、 - - - - - -第 13 页，共 16 页来引导定语从句；而that 既可以指人，又可以指物。另一类是关系副词，常用的有where（表地点），when（表时间）及why（表原因）。本例中的先行词指人，所以应把which 改成 who 或 that 。2 The main topic people are often talking about it at present is the construction of the Yangtze Three Gorges Dam 分析the main topic是先行词， people are about it at present是定语从句

74、 的形式表示。故本例可改成：This is a new type of airplane, whose parts are all made at home或者 This is a new type of airplane, the parts of which are all made at home7 Anything which exists in the universe has its two sides分析当先行词是表事物的不定代词，如all,everything,anything 时 ,关系代词要用that ，而不用 which ，故本句要把关系代词which 改为 that 。
