四、同义词（近义词），反义词（对应词）的词类及用法

例如：

1．any和some

二者都有“一些”的意思，any多用于疑问句和否定句，some 多用于肯定句。但在表示请求、邀请、期待肯定答复的问句中，常用some代替any。

2．borrow lend

borrow常和from搭配，表示“借来”“借入”

lend常与to搭配，表示“借给……”“借出”

──Will you please lend me your bike?

──Sorry, I've lent it to Tom．

──Thank you all the same．I'll borrow it from others．

3．take, bring, carry

take：将某物或某人带离说话人那里。bring则相反，是带到说话人处。例如：

Bring your book here tomorrow．

Could you take it to the classroom?

carry是随身携带，不表明来去的方向，如：

I can't carry the box．It's too heavy．

4．find, look for, find out

find意为“找到”，look for是“寻找”，find out 是“发现、查明（真相）”

5．look, see, watch

look是“看”，经常和at搭配，look at　看……　如：Look at the picture．

see是“看见”。如：Can you see the picture?

watch是“观看”如：I was watching TV at ten yesterday．

6．other, the other, others, another

other可作为形容词，意为“其他的”如：What other things can you see?

要注意掌握one…the other的用法，表示（两者中的）一个…另一个，如：

others泛指另外的人或物。the others表示特指某范围内的“其他的人或物”，如：

Some students are playing basketball, （the）others are playing football．

another意为“另一个”。如：I want another apple．

7．speak, say, talk, tell

speak重在指人们对语言的掌握或使用。say强调说话的内容，talk指交谈或连续说话, 常与with或to搭配。tell意为告诉。如：

I can speak a little English．

What are they talking about?

Can you tell me the way to the cinema?

8．too, also, either

too, also, either都表示“也”。too用在句末，只用于肯定句。also置于句中，也只用于肯定句。either通常置于句末，用于否定句。如：

I am a teacher, too．

She is also a teacher．

He isn't a teacher, either．

9．reach, arrive, get to

三者都表示到达。“get to +地点”多用于口语。reach是及物动词，后面直接加地点。arrive是不及物动词，要用介词in或at再加地点，较大地点用in，较小的地点用at, 如：

Have they arrived in Beijing?

10．cost, pay, spend

cost的主语只能是“物”，不能是人。spend一般是用人而不是用物做主语。cost表示“值（多少）钱”“花费”，spend表示“花费”“度过”。pay表示付款。

可以记住下列句型：

1）主语（物）＋cost＋sb．＋sth．

2）主语（人）＋spend＋...＋ in doing sth. / on sth.

3）pay与for连用，主语（人）＋pay for ...

请看例句：

I paid ten yuan for the book．

I spend ten yuan on the book．

The book cost me ten yuan．
