two

years

ago.

(2)both直接修饰名词时,不加of。如:

children.

②I

both

of

them.

2)both与动词连用

当both在句中作主语的同位语时,也可与动词连用,both在句中的位置有以下三种情况:

(1)放在是动词be之后。如:

①The

children

are

both

lovely.

②They

are

both

【注意】在感叹句或简略答语中,both应置于be之前。如:

他们俩多漂亮啊!

④----Are

you

both

from

Japan?

----Yes,we

both

are.

“你们俩都是日本人吗?”“是的,我们是。”

(2)放在行为动词前。如:

①We

both

like

watching

TV.我们俩都喜欢看电视。

②The

men

(3)当谓语动词是由几部分组成时,both要放在第一个助动词后面。

如:

①We

both

studied

acting.

我们俩都学过演戏。

②The

rooms

have

both

been

cleaned.

这两间屋子都已打扫过了。

3)both作代词时,可单独使用,其后不接名词。如:

①The

brothers

are

good

at

playing

basketball.

Both

will

take

part

in

the

game.这弟兄俩人篮球打得好,他们俩都将参加比赛。

②----Which

one

do

you

want?

----I

ll

take

both

please.

“你要哪一个?”“两个我都要。”

【注意】both与not连用,是部分否定。如:

are

not

open.
