Alice,
please
take
a
raincoat.
爱丽丝,请带上雨衣。
用于表达命令、请求、劝告、警告、禁止等的句子叫做祈使句,祈使句因对象(即主语)是第二人称,所以通常都省略。
例句:请坐!
Sit
down,
please!
拓展:一般祈使句的否定句有以下3种形式
(1)Don’t+动词原形
Don’t
make
any
noise.不要制造噪音。
(2)No+动词ing
No
smoking!禁止吸烟!
(3)No+名词
No
photos!禁止拍照!
以Let
开头的祈使句表示建议,构成形式为“Let+宾语+动词原形”。本句“Let’s”
为“Let
us”
的缩略形式。
例句:咱们去购物吧。
Let’s
go
shopping!
2.
Let’s
take
out
our
raincoats!
咱们把雨衣拿出来吧。
拓展:以Let
开头的祈使句的否定形式是在Let前加
Don’t或在动词前加not。
如:不要让她在墙上乱写。
Don’t
let
her
write
on
the
wall.
3.
Let’s
put
them
on.
让我们穿上吧。
put
on?“穿上、戴上”,强调“穿”“戴”的动作,
后接衣服、鞋帽等。
