定语从句中只用that不用which的情况

关系代词指代某物事时，只用that不用which的情况1.当先行词是everything,anything,nothing（something除外,用which或者that均可）,all,none,few,little,some等不定代词时，或当先行词受every,any,all,some,no,little,few,much等词修饰时。如：2.先行词被序数词或形容词最高级修饰时。3.先行词被thevery，theonly，heright，thefirst，thelast等修饰时4.先行词前有thesame修饰时如果表示和先行词是同一物时用thesame…that…ThisisthesamepursethatIlostyesterday.这就是我昨天丢的那个钱夹。如果表示与先行词同一类或相似的某物，则用thesame…as…ThisisthesamepurseasIlostyesterday.这个钱夹和我昨天丢的那个一样。5.先行词是并列结构，既有人又有物时6.先行词为数词时Lookatthebooksonthebookshelf.Youcanseethetwothatyouboughtmeformybirthday.7.避免重复原则，当先行词前面有who,which等疑问代词时8.关系代词在定语从句中作表语时，而且通常省略Myhometownisnolongertheplacethatitusedtobe.9.关系代词在therebe句型中作主语时,而且常可以省略。如：Thisisthefastesttrain(that)therehaseverbeen.10.……thewaythat……(…thereasonthat…/…thecausethat…)英语语法顺口溜：定语从句只用that情况口诀：先行不定代，thevery/only/first有高,序，some,all,much,few;指物人，有了which/who英语语法顺口溜：定语从句不用that的情况that用法真有趣，两个地方它不去;逗号后边它不去，介词之后不考虑;
