你好!
如果用be的话
后面得就跟形容词
名词
如果用动词的话,就是动词原形
将要发生什么或者做什么
明白了吗?
希望能采纳,谢谢
记得给问豆啊!
不会存在be
后面加动词原形的。除非这个动词的过去分词跟原形是一样,表示被动。
动词分为系动词、实义动词、情态动词等。
be
动词的原形就是
be..
In
downtown
Los
Angeles,
it's
going
to
be
sunny
and
clear
tomorrow
morning.
In
the
early
afternoon,
it's
going
to
be
windy.
In
the
late
afternoon,
it's
going
to
be
cloudy这三个句子都是说天气情况的,sun、wind、cloud、都是名词,不可以直接跟在it's
going
to
后,所以要借用be动词,be就是动词原形,这样才符合语法。
In
the
early
evening,
it's
going
to
rain
in
downtown
Los
Angeles.
But
in
the
mountains,
it's
going
to
snow.这两个句子虽然也是说天气,但是rain、snow都可以作动词使用,故不用借助be动词。希望对你有帮助!!!!!
