He never reads____is not worth reading

问题描述:

He never reads____is not worth reading
A which B what 为什么不能选A

He never reads. 他从不阅读. 句子语法正确完整, 不需要加宾语.
如果加上宾语.
He never reads books. 他从不读书. 句子也正确.
再看你的例子
He never reads ()...
()中一定是宾语. which可以引导宾语从句, which指代主句中的宾语. 但是, 你现在主句中没有宾语. 所以放which是不对的.
He never reads anything (that) is not worth reading.
He never reads books, which are not worth reading.就是正确的了.1、我觉得()中应该是主语,因为read后面的应该是宾语从句,从句缺少主语2、Can you tell me which boy is your son这是我在语法书上找到的一个正确句,主句中没有宾语,which引导宾从,并在宾从中当主语。为什么这个能用which3、He never reads anything that is是因为有anything所以填that,可这道题没有anything1、我觉得()中应该是主语,因为read后面的应该是宾语从句,从句缺少主语2、Can you tell me which boy is your son这是我在语法书上找到的一个正确句,主句中没有宾语,which引导宾从,并在宾从中当主语。为什么这个能用which3、He never reads anything that is是因为有anything所以填that,可这道题没有anything

  1. 你要知道, 宾语从句, 从句修饰指代了主句中的宾语. 你现在主句中连宾语都没有, 怎么会有宾语从句.

  2. 先把句子变成陈述语序.

    You can tell me which boy is your son.

    You can tell me (something 宾语).

    (something 宾语)= which boy is your son.

    这里which不是引导从句的which, 是"哪个"的which.

  3. 这只是让句子合理通顺. 只是个例子罢了.
