(3)each可作主语、同位语、定语和状语,而every只能作定语。

2. interest,interesting与interested

(1)interest作名词,意为“兴趣,趣味”,用作动词时指“使(人)产生兴趣”。

例如:    He shows an interest in music.    他对音乐感兴趣。

(3)interested是由动词interest加-ed构成的形容词。意为“感兴趣的”,其主语一般是人,常用于be/get/become interested in结构中,表示“对……感兴趣”。

例如:

3. how long,how often 与 how soon

4. have与must

have to与must都有“必须”的意思,但有其不同之处:

(1)have to有时态和人称变化,带有客观因素,意思是“不得不”;must无时态和人称变化,后面接不带to的不定式,带有主观因素,意思是“必须,一定”。

例如:

I have to go now.It's dark.    我必须得走了。天已黑了。

I must go.    我得走了。

(2)must not表示“不许,一定不能”;don't have to表示“不必”。

You don't have to go so early.    你不必走那么早。

(3)Must I…?的否定回答是No,you needn't.或No,you don't have to.

--Must I stay here now?     我必须留在这吗?

--NO,you needn't./you don't have to.     不,你不必。

8. C

9. D

10. A  of后接名词或相当于名词的词语。

4. C   短文第二段最后一句“At mouths of rivers,fresh water joins the salt water of the ocean.”已提供了明显的信息。

本题考察的是日常交际用语的运用能力。要求给每个句子配位。在理解各句的句意后,运用日常交际用语在不同场合的应答,就能逐一完成。如本题第一句的“Hello, who’s that, please?”根据II栏中E项的答语“This is Mary speaking”可以推断出这里电话用语(请问您是哪位)。再如第四句“Would you like to come to supper?”(你来吃晚饭好吗?)按照英美人士交际习惯,应该先说表示乐意,并致谢,就不难找到II栏中的a项应答。
