外研版必修3Module5學案
非限制性定語從句舉例：
(1) his mother, who loves him very much, is strict with him.
(2) china, which was founded in 1949, is becoming more and more powerful.
要注意區分以下幾個句子的不同
(1) his brother who is now a doctor always encourages him to go to college.
他那當醫生的哥哥常鼓勵他要考上大學。（他還有其他的哥哥）
(2) his brother, who is now a doctor, always encourages him to go to college.
他的哥哥是當醫生的，常鼓勵他要考上大學。（他只有一個哥哥）
難點分析
（一）限制性定語從句只能用that的幾種情況
1.當先行詞是anything, everything, nothing (something 除外), few, all, none, little, some等代詞時，或者是由every, any, all, some, no, little, few, much等修飾時
(1) have you taken down everything that mr. li has said?
(2) there seems to be nothing that seems impossible for him in the world.
(3) all that can be done has been done.
(4) there is little that i can do for you.
注意：當先行詞指人時，偶爾也可以用who
(4) any man that/.who has a sense of duty won’t do such a thing.
2. 當先行詞被序數詞修飾
(1) the first place that they visited in london was the big ben.
3. 當先行詞被形容詞最高級修飾時 (1) this is the best film that i have seen.
4. 當形容詞被the very, the only 修飾時
(1) this is the very dictionary that i want to buy,
(2) after the fire in his house, the old car is the only thing that he owned.
當先行詞指人時，偶爾也可以用who
(3) wang hua is the only person in our school who will attend the meeting/
5. 當先行詞前面有who, which等疑問代詞時
(1) who is the man that is standing there?
(2) which is the t-shirt that fits me most?
6. 當先行詞既有人，也有動物或者物體時
(1) can you remember the scientist and his theory that we have learned?
（二）關系代詞as和which引導的定語從句
as和which引導非限制性定語從句，有相同之處也有不同之處。具體情況是：
1.as和which都可以在定語從句中做主語或者賓語，代表前面整個句子。
(1) he married her, as/which was natural.
(2) he was honest, as/which we can see. 新課標第一網
2. as 引導非限制性定語從句，可放在主句之前，或者主句之后，甚至可以切割一個主句；which引導的非限制性定語從句只能放在主句之后。另外，as有“正如……，正像……”的意思
(1) as is known to all, china is a developing country.
(2) he is from the south, as we can see from his accent.
(3) john, as you know, is a famous writer.
(4) he has been to paris more than several times, which i don’t believe.
