这是一辆二手车英语,这辆二手车来自哪里英语

您好，这两个例句的解释为：

1）Recently I bought a second-hand car, the price of which was reasonable.

这个句子其实是两个句子合并为主从句结构：

A）Recently I bought a second-hand car.

B）The price of the second-hand car was reasonable.

可以看出合并后，which 替代了A句的宾语（a second-hand car）。假如把 of which 从合并句中去掉，就变成了 Recently I bought a second-hand car, the price was reasonable. 此时会被判为（断句），因为是两个完整的分句，但没有任何的连词把两个句子串在一起。

要变为定语从句，通常会使用 whose 引导词变为 Recently I bought a second-hand car, whose price was reasonable. whose 这个引导词在定语从句中充当（定语），而 whose 是 who 的所有格形式，而 of 又是从属介词可以用来引导所有格，那么 whose price 就可以变成了 the price of which（of 起到了 price = which 的从属结构），此时的 of which 可以看作为（介词短语）作 the price 的后置定语，因为这个的价格，修饰 the price，而 which 又替代主句的（宾语），所以这个 of which 的（介词短语）实际上是（介词）+（主句的宾语）。

Recently I bought a second-hand car, the price of the second-hand car was reasonable.

= Recently I bought a second-hand car, whose price was rasonable.whose 作定语

= Recently I bought a second-hand car, the price of (which=the second-hand car) was reasonable.假如没有了 which 替代主语的（宾语），定语从句结构就不存在了。

这里的（介词宾语）概念和传统的（介词宾语）作不及物动词的宾语的概念是不一样的。比如 I dream of a big house. 这里的 of a big house 也是（介词宾语）充当不及物动词 dream 的宾语。

2）She might possibly come, in which case I'll tell you.

这里的 which 在从句中充当了定语，表示有选择性的，因为 case 有两种结果，一种是来，一种是不来，也就是不论来了，还是不来，这两种情况，不论哪一种发生了，我都会告诉你。

这个句子也可以分成三个句子：

A）She might possibly come.

B）I'll tell you in this case. (in this case = in the case that she comes = if she comes)

C）I'll tell you in that case. (in that case = in the case that she doesn't come = if she doesn't come)

which 作为定语，表示有限制范围的选择性，比如 Which one do you like? 所以 in which case = in this case + in that case 的选择性，所以 which 就变成了（定语）修饰 case 了。

这两种 which 的用法都是比较特殊的用法，因为 which 作为关系代词引导定语从句时，并不充当主语或是宾语，而是充当主句的一部分，或是充当定语的用法了。
