be good for：对……有益 Drinking more water is good for you.
be good to：对……好/和善 She is very good to her neighbors.

4.①I guess…这一结构与I think…类似，表达“我想……”，用于陈述自己的观点、看法及建议。

guess用作及物动词，意为“猜测；估计”，后面可接名词、代词或从句。

I can only guess the reason． I guess (that) he is right．
②“I guess+宾语从句”句型在变为否定句时，要否定主句，而否定的意义留在从句，这种现象
叫“否定转移”。

I don’t guess (that) he is right. 我认为他不对。

5.①big deal是固定搭配，意为“重要的事”，作否定用法时，常用于It’s not a big deal或It’s no
big deal.表示说话人并不认为某事有什么了不起。

②big deal也经常用于肯定或疑问结构中。

Peter, I think it’s a big deal for you. What’s the big deal? It’s only a party.

7.offer to do sth. 意为“主动提出做某事”。

辨析offer与 provide
offer ：主动提出；自愿给予；提供；常用于offer sb. sth. 或offer sth. to sb.结构
She offered me a job. = She offered a job to me.
provide：为做好准备而“提供；供应”；常用于provide sb. with sth. 或provide sth. for sb.结构
The school provided food for the students. =The school provided the students with food.
8.辨析leave与 forget
leave ：遗留；落下，指把某物忘在某地，其后接地点状语。

She left her keys in the room.
forget ：“忘记”，指由于记忆上的忽略而忘记了某人或某事物，后面可接名词、动词不定式或动词ing形式，不可接地点状语
I forgot her address.
9.be afraid of sb. /sth.：害怕某人或某物 The boy is afraid of his mother.
be afraid of doing sth.：害怕做某事，侧重主语担心、害怕某事发生 She is afraid of making
mistakes.
be afraid to do sth. ：不敢或害怕做某事，侧重主语不敢做某事 She is afraid to dive.
be afraid + that从句：恐怕，多用于客气地提出个人意见或看法 I’m afraid that I can’t go today.
10.辨析： compare… with…与 compare… to…
compare… with…：“把……与……比较”，常用于两个同类事物之间的具体比较，侧重区别
We compared this picture with that one.
compare… to…：“把……比作……”，常用于两个不同性质的事物的抽象比较；compare…
to…还可以
译为“把……与……比较”，此时可与compare… with…互换

11 although,so that及until的用法
(I)although意为“尽管；虽然”，引导让步状语从句，不能与but同时用在一个句子中，although的
同义词为though。

(II) so that意为“为了；以便”，引导目的状语从句和结果状语从句。

(III)) until意为“直到……为止”，引导时间状语从句； not… until意为“直到……才”。

until引导的从句，主句是延续性的动词，与短暂性动词连用时用not… until。

[注意] until引导的从句不用将来时。
