As is known, the earth is round, not flat.

7、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.

二、课内探究

（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。

②强调it无意义，that / who不是引导词。

③强调it is / was和that / who后如果句子意思讲得通则是强调句，讲不通则不是。

It is the museum that / which we visited last year.(定语从句)

It was in the hotel that we stayed last night.（强调句）

（3）定语从句与同位语从句的区别。

①定语从句引导词被称为关系词，that充当主语、宾语、表语。有时可省略。

②同位语从句引导词被叫做连词，that不能充当任何成分，不可省。

Word came that their army was defeated.(同位语)

We expressed to them our wish that was the same as their.(定语)

（4）关系词在从句中省略的情况。

①关系词作宾语，前无介词时。

②关系词作表语。

（5）限制性定语从句与非限制性定语从句的翻译。

（6）关系词前有介词或复杂介词，关系词只能是which和whom。

（7）几个特殊的定语从句句型：

①He is the only one of the students who has got very good marks in the match.（句中one为先行词）

He is one of the students who have got good marks in the match.（句中students为先行词）

②Is this place the one (that) we visited yesterday？ Is this the place (that / which) we visited yesterday?

③He stood at the window, from where he could see what was happening.

④It may rain, in which case the match will be put off.
