Language
points
1.
Don’t
leave
your
things
like
this.
不要把你们的东西这样放。
(1)此句为否定祈使句，用来提醒或警告别人不要做某事。don’t是
do
not的缩写形式，意为“不要，别”。否定祈使句的结构是：Don’t
+
动词原形
+
其他.
例句：Don’t
open
the
activity
book.
不要把活动手册打开。
(2)我们以前学过like的意思是“喜欢”，但本句中like的意思是“像；如同”，常构成短语look
like…(看起来像……)。
例句：You
can
draw
pictures
like
this.
你可以像这样画。
2.
Put
them
away.
把它们收起来。
这是一个以动词原形开头的Do型祈使句。祈使句的主语通常为第二人称(you)，但一般都被省略，所以用于祈使句句首的动词总是用原形，不能用其他形式。句型结构为：动词原形
+
其他.
例句：Come
here.到这里来。
Open
the
book,
please.请打开书。
拓展：Do型祈使句的用法口诀：
Do型祈使句，它的主语（you）常省去；
表示请求或命令，加上please表客气；
如果变成否定句，使用don’t是规律。
