状语从句（2h）

教学目标：掌握9大状语从句及其中重要的引导词与句型。由于高考中状语从句经常和从句的时态语态，动词短语的搭配，以及状语从句的省略，虚拟语气与倒装一起考查。因此必须掌握好：

1 时间状语从句中各种引导词引导的主句与从句的时态的判断

2 地点状语从句中表示抽象含义时从句必须在主句之前

3 原因状语从句中because，as，now that的位置问题

4 目的状语从句中的so that与在结果状语从句中的区分

5 结果状语从句中的so/such…that…的特殊结构及其倒装

6 条件状语从句中的if，unless的用法

7 方式状语从句中的虚拟语气的用法

8 让步状语从句中的as, though做引导词时的倒装用法

教学重点：1 掌握常用的状语从句中的引导词

2 判断状语从句中的时态

3 状语从句中的倒装情况：no sooner…than, hardly/scarcely…when, not…until用于句首时的倒装；结果状语从句中so/such置于句首时的倒装情况；as/though引导的让步状语从句的倒装情况

4 as if/though引导的方式状语从句中的虚拟语气

教学进程：

导入：状语从句在句子中作状语，修饰谓语。

㈠时间状语从句

⒈回顾有哪些词可以引导时间状语从句—when, while, as表示“当…时”; immediately, instantly, as soon as, directly, the moment, no sooner than, hardly when, scarcely when, once表示“一…就…”；till, until, not until表示“直到…才”；before 表示“还没来得及…就…”，“不到…就…”；since表示“自从…”；every time, each time, next time, the first time, any time, all the time表示“每当…”，“每次…”，“下次…”等等

⒉状语从句中的时态的判断方法：

⑴过去，现在，将来

⑵延续性与非延续性/时间点与时间段

⑶主从句中的谓语动词的先后关系

⑷判断开始时间与截止时间

⒊when, while, as都可以表示主从句动作同时进行(口头造句举例)

如：when the music fades away, people tide away.

She sat there alone while others were all dancing.

He dances joyfully as the music goes.

当主句动词为短暂性，从句动词用延续性动词的进行时态表示一段时间内的动作时，三个词可互换。如上面的第二个句子。

When可引导持续动作亦可引导短暂动作。如

When I was young, I used to play Barbie dolls.

While引导的必须为延续性动词，侧重和主句中的动词相对比。如

While he was making the breakfast, his wife was sleeping.

As可以指主从句的动作交替进行。如

She feels someone’s following her, so she walked fast as lotoked back.

⒋“一…就…”

⑴The moment she heard the music she liked most, she stood up to dance.

⑵Hardly had the Cinderella got home when the clock knocked 12 o’clock.

⑶As soon as I get there, I’ll let you know.

(强调当no sooner than和hardly when, scarcely when提到句首时要用到倒装)

⒌till, until, not…until

⑴肯定句：主谓语必须为延续性动词

You can dance to your joy until you feel tired.

⑵否定句：主从句必须为非延续性动词

You can’t marry him until I say yes.

（强调till不能放句首，until可以）

6. before

⑴I hadn’t finished my sentence before he turned his back to me。

⑵It will be 2 years before I get back.

7. since

I haven’t spoken to him since 1 year ago.

It is 3 years since I smoked.

It has been 3 years since I smoked.

8．Every time…

歌词：every time I leave to head out on the road, I wanna take you with me, save me from the cold.

练习：

1 We usually call someone a green hand ____(当他没有经验)his job.(experienced)

2 I was speaking to Ann on the phone___（突然我们短线了)(cut)

㈡地点状语从句

表示抽象含义时，从句需在主句前。如

Where there are girls, there is gossip.

where引导的定语从句与状语从句

You’d better make a mark where you have any questions.（状从）

You’d better make a mark at the place where you have any questions. (定从)
