Do you know Mr.Smith whose story is very moving
There is a room， whose window faces the river.
There is a room， the window of which faces the river.
10、關系代詞as，在從句中作主語、賓語和表語。
（1）先行詞被such和the same修飾，或句型as many（much）中，從句都用as 引導。
Such books as you bought are useful.
The school is just the same as it was 10 years age.
注意：區別①such … that … 引導的結果狀語從句。They are such
lovely children that we love them much.②the same … that … 引導定語從句。I want to use the same tool that you used just now.
（2）無先行詞的定語從句用as和which引導。
區別：①意義上：as 含有“這點正如……一樣”。②位置上：as 從句可置句首，也可在另處。
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、關系副詞when與where、why、that
when 指時間 = in / at / on / during which
where指地點 = in / at / from / which
why指原因 = for which
當先行詞為way、day、reason、time時，可用that作關系副詞。（非正式場合）
I don’t like the way that / in which / he talks.
當time作先行詞時，關系詞可以省掉。
This is the first time I have given you a lesson in French.
12、必須注意的問題
（1）關系詞作主語時，從句中謂語的數。
（2）注意區別定語從句與強調句。
①定語從句中關系詞作從句成分，復合句。
