我优求知网介词后面定语从句
英语最早被中世纪的英国使用，并因其广阔的殖民地而成为世界使用面积最广的语言。下面是为大家整理的介词后面定语从句，欢迎阅读与收藏。
1.由“介词+关系代词”
引导的定语从句主要用于正式文体，在非正式文体中通常将介词放至句末。如：This is the man to whom I referred. 我指的就是这个人。This is the man (whom) I referred to. 我指的就是这个人。
2. 直接用于介词后作宾语的关系代词which不能换成that，直接用于介词后作宾语的关系代词whom不能换成who：
介词用于句末，则用作宾语的which, whom也可换成that, who，或者省略不同。如：这是一个我们讨论了许多的问题。This is a subject about which we have talked a lot.(which不能换成that，也不能省略)This is a subject which we have talked about a lot. 这是一个我们讨论了许多的`问题。(which可以换成that，也可以省略)
3. 关系副词when, where, why根据情况有时可换成“介词+关系代词which”。
如： That is the day when [=on which] he was born. 那就是他出生的日子。That is the house where [=in which] he lived. 那就是他住过的房子。That is the reason why [=for which] he must apologize. 那就是他必须道歉的原因。
4. 在很正式的文体中，“介词+关系代词”引导的定语从句可紧缩成“介词+关系代词+不定式”结构。
如：在那儿孩子们有个玩耍的花园。正：There the children had a garden in which to play. (很正式)正：There the children had a garden in which they could play. (较正式)正：There the children had a garden to play in. (较口语化)注：这类“介词+关系代词++不定式”结构中的介词不能没有，也不能放在句末。如不能说There the children had a garden which to play in.

我们将尽我们的最大努力来保护那些濒危的动植物。
(2) There is much that I wan to tell you.
我有很多想要告诉你的话。
(3) Is there anything that I can do for you?
有什么我可以帮你的吗？
2. 先行词被all, every, no, some, any, (a)few, (a)little, much等限定词修饰时。如：
(4) You can borrow any book that you want to read in our school library.
在我们***书馆，你可以借任何你想读的书。
3. 先行词被序数词或形容词最高级修饰时。如：
（5）This is the most beautiful city that I've ever seen.
这是我见过的最漂亮的城市。

这种风格的画我们仅有一幅。
5. 先行词是并列结构，既有人又有物时。如：

6. 先行词前有the same 修饰，表示和先行词是同一物时。如：
（9）This is the same purse that I lost yesterday.

注：如果表示的是与先行词同一类或相似的某物，则用the same…as….如：

（12）They built a factory which produced things that had never been seen.
他们建了一工厂，生产以前从未见过的东西。
9. 以which作主语开头的特殊问句，为了避免重复，定语从句用that。如。
