状语从句教案课程

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) ㈢原因状语从句

回顾有哪些引导词—because, since, as, now that, seeing that, considering that,

It is silly of you to take his words when every one tells you he’s a liar. ㈣目的状语从句
