that修饰从句和which一样需要介词前置/介词提前吗?
我知道which做修饰的事后需要介词提前;比如:from which / at which / about which
那么有 about that吗?比如我想说:python——the computer language that i want to learn about 还是说 python——the computer language about that i want to learn?我不想用which 我想表达十足的限定性修饰。第二句这么写对吗
不对的。只有介词+which这个结构,没有介词+that(当然,in that除外,这个词等于because,不再是定语从句了)。关于限定性和非限定性这个问题,它们的本质区分不在乎于关系词用which还是that,而是看先行词是否和定语从句之间用逗号隔开。如果隔开了,就是非限定性的。反之,则是限定性的。因此,例句中,应该用python——the computer language that i want to learn about 或者python——the computer language about which i want to learn。这两种写法的意思完全相同。
