in which后面用什么时态？

in which后面用什么时态？

例句 ：

He used to keep a notebook,in which were writen the namesof his friends .

翻译：他过去常常保留一本笔记本，上面写了他朋友们的名字。

此题考查定语从句和倒装句型。

1. 非限制性定语从句中的关系代词which代指先行词notebook，放入定语从句中为：

in which were written the names of his friedns

= the names of his friends were written in which

= the names of his friends were written in the notebook

2. 定语从句采用了全部倒装，即把状语in which提前，中间是谓语were written，主语the names of his friends置后。

句子主语the names of his friends为复数，时态为一般过去时，所以be动词用were.

In which 用法，可以理解成将 in 从后面的子句中搬到前面来，让原本可能冗长的句子，变得很精简。

例一：I saw a movie in which the villain goes to jail.

我看了一部关于坏蛋被关进监狱的电影。

注意，这句子其实是这样子的：

I saw a movie.

+

The villain goes to jail in the movie.

=

I saw a movie in which the villain goes to jail

例二：You have 7 days in which you can cancel the contract and get your money back.

你有七天的时间可以取消合约跟拿回你的钱。

You have 7 days.

You can cancel the contract and get your money back in the 7 days.

上面这两个句子相加，用了in which 的用法之后，就成了原句。

You have 7 days in which you can cancel the contract and get your money back.
