一．听1a 回答下列问题。

6. 喧闹地________________

7. 匙，调羹________________8. 叉，餐叉________________

9. 筷子___________________

三.if /whether 引导宾语从句时指“是否”

如：

1. I don’t know if/whether I need to obey all the rules while I’m having dinner with my friends. 2. Could you tell me if/whether it’s polite to speak loudly at the table? 3. I don’t know if/whether you are right. 四．通过阅读你能找出多少if或whether引导的宾语从句？

_____________________________________________________________________________ _____________________________________________________________________________ ______________________________________________________________________________ _____________________________________________________________________________ ______________________________________________________________________________ if和whether都可译为\"是否\"，二者引导宾语从句时通常可以互相替换，而以下几种情况中, 只能用whether:

1. 强调两方面的选择，特别是句中有or not时。如：

Let me know whether you can come or not.

2. 宾语从句前置时。如：

Whether this is true, I can\'t say.

3. 引导主语、表语、同位语从句时。如：

Whether the football game will be played depends on the weather. （主语从句）

The question is whether he can do it. （表语从句）

The question whether we should go with them must be decided at once. （同位语从句）

4. 在介词之后作介词的宾语时。如：

I haven\'t settled the question of whether I\'ll go back home.

5. 在不定式前与不定式一起组成词组时。如：

Whether to go or stay is still a question.

6. 在discuss, decide 等动词后作宾语时。如：

We discussed whether we should go there by plane.

值得注意的是：

if还可以引导条件状语从句，是\"假如；如果\"之意，而whether可以引导让步状语从句，是\"不管；无论\" 之意。如：

If you ask him, he will help you.

I shall go, whether you come with me or stay at home. 五、副词比较级最高级:

1. 单音节词，
