There is a room， whose window faces the river.

10、关系代词as，在从句中作主语、宾语和表语。
（1）先行词被such和the same修饰，或句型as many（much）中，从句都用as 引导。
Such books as you bought are useful.
The school is just the same as it was 10 years age.
注意：区别①such … that … 引导的结果状语从句。They are such
lovely children that we love them much.②the same … that … 引导定语从句。I want to use the same tool that you used just now.
（2）无先行词的定语从句用as和which引导。
区别：①意义上：as 含有“这点正如……一样”。②位置上：as 从句可置句首，也可在另处。
He didn’t pass the exam， as we had expected.
There is lots of air in loose snow， which can keep the cold out.
As is known， the earth is round， not flat.
11、关系副词when与where、why、that
when 指时间 = in / at / on / during which
where指地点 = in / at / from / which
why指原因 = for which
当先行词为way、day、reason、time时，可用that作关系副词。（非正式场合）
I don’t like the way that / in which / he talks.
当time作先行词时，关系词可以省掉。
This is the first time I have given you a lesson in French.
12、必须注意的问题
（1）关系词作主语时，从句中谓语的数。
（2）注意区别定语从句与强调句。
①定语从句中关系词作从句成分，复合句。
