先行词是time,用that/which引导一个定语从句,能举个例子么 定语从句中that本身是先行词,例the clock is that which tells the time这句话感觉翻译不通顺.that是做什么的 定语从句,先行词time在后句中作时间状语时,关系词是用in which还是at which? 先行词是代词时关系词用which还是that? others做先行词,其后的关系代词是用who还是that还是which? 句子：It is suggest that the time and the way in which/that the news is broadcast be changed.个人认为此句有两个先行词THE TIME和THE WAY,在我的记忆里,THE TIME后面只能跟WHEN 和AT WHICH ,为什么此句用的关系词是in whi 先行词是专有名词时,用哪个关系代词引导定语从句是用THAT 还是用WHICH引导? AS IS KNOWN TO ALL当先行词是句句子时,连词一定要用AS吗,THAT和WHICH呢 先行词（that、which、when、where）是物的定语从句怎么造? every后能加which吗?先行词是every word,关系代词除that外,可以是which吗? 定语从句中 先行词是those 用THAT还是which引导先行词是those 时用什么列:Don't hesitate to do those -----are worth doing为什么一定用that 先行词是不定代词或者先行词被不定代词所修饰时,关系代词通常只用that,不用which.请问,此时that可以省略吗? those做定语从句的先行词,用什么关系代词?which还是that?为什么? the thing 作先行词,定语从句用which还是that,还有都可以? 英语的关系代名词的用法that,which,还有先行词的用发 先行词的使用什么时候用where,什么时候用which,什么时候用that 什么时候用 in which ? Is there anything which you want?先行词为anything时不是要用that的吗?为什么用which? the last time做先行词一定要加that对吗
