二. 重點、難點：
定語從句及單項選擇訓練
三. 具體內容:
定語從句專講專練
概念：在含有主句和從句的復合句中，修飾主句中的某一名詞或代詞的從句叫做定語從句。它所修飾的詞叫先行詞。定語從句就跟在先行詞的后面。用來引導定語從句的詞叫關系詞，分為關系代詞（who, whom, that, which, whose）和關系副詞（where, when, why）。
e.g. did you see the person who/that stole it?
this is the pen which/that he is looking for.
上面兩例中的先行詞分別是the person與the pen，后面是由關系代詞who/that; which/that引導的定語從句。
2. 關系代詞的選擇及功能。
引導定語從句的詞有關系代詞who, that, which, whom, whose和關系副詞where, when, why。它們放在先行詞和定語從句之間起聯系作用，同時又充當定語從句中的一個成分（如主語或賓語）。有關先行詞的選擇取決于兩點：先行詞是人還是物；關系代詞在從句中做主語還是賓語。具體用法如下：
1）當先行詞是人時，關系代詞可以用who或that；當先行詞是物時，關系代詞可用which或that。
e.g. the film which/that they saw was very interesting.
the boy who/that is sitting in the sun is my brother.
2）當關系代詞在句中做賓語時，關系代詞可以省略。
e.g. the man （who, whom, that）they are waiting for comes from japan.
3）whose 指人或物的所有格。
e.g. do you know the boy whose hair is yellow?
the classroom whose windows are closed is ours.
4） 關系副詞when, where, why = 介詞+ which
when 表時間，跟在hour, moment, day, month, year, season, time等之后。
e.g. can you tell me the date when/on which you were born?
where 表地點，跟在place, village ,town, city, home等之后。
e.g. this is the place where/in which i grew up.
why表原因, 在 reason（原因）之后。
that’s the reason why she didn’t come to work.
3. 特殊情況
1）當先行詞被形容詞的最高級或序數詞修飾時，關系代詞必須用that。
e.g. this is the best novel （that ） i have ever read.
2）如果指物的先行詞是不定代詞或被不定代詞修飾時，必須用that，不能用which。
不定代詞有all, something, everything, anything, nothing, none, the one, much, little, every, any, some等。
e.g. i mean the one （that）you talked about just now.
3）當先行詞有the only, the very, the last, the same, the first等詞修飾時，關系代詞必須用that。
e.g. he is the only person（ that ）i saw there.
4）關系代詞在定語從句中作介詞的賓語時，如果介詞放在它的前面，只能用which或whom。
e.g. this is the room that/which he lived in two years ago.
=this is the room in which he lived two years ago.
the girl who/whom/that he is talking to is my sister.
=the girl to whom he is talking is my sister.
但有些介詞短語的固定詞組不能拆開
