第1个问题
decide是只能搭配to
do的
至于第2个问题
spent是spend的过去式,当然也可以自己做形容词。做形容词的意思是用尽的,
精疲力尽的,
失去效能的;当作为spend的过去式时,用法随时态而变。spend的用法如下:在表示“花费”时,spend
可以用于被动语态。如:Two
hours
was
spent
on
the
work.
做这工作花了两个小时。
spend可用于比喻用法中,表示“表示消耗”“用完”。如:
I’ll
spend
no
more
breath
on
him.
我不会再和他费唇舌。
He
spent
great
efforts
to
help
me.
他费了很大的劲儿来帮我。
一般情况下,Spend
搭配
in
或者
on
Spend
on
sth
花在某方面
spend
in
doing
sth
花在做某方面
基本就是这两个搭配了。
聪明滴俺知道!!
(1)decide只能跟to
do连用,不能接doing
sth.
(2)spend(花费)+钱+on+(名词or代词)
如:I
spend
two
yuan
on
the
pen.(我花了两块钱买这支笔。)
spend(花费)+钱+in+doing
sth.(“in”
可省略)
如:I
spend
two
yuan
(in)buying
the
pen.(我花了两块钱买这支笔。)
另外:spend(度过)+时间+名词(主语是人)
如:I
spend
Spring
Festival
with
my
parents.(我和爸比妈咪一起度过春节。)
decide
只能接to
do形式,
还能接on
sth,不能接
doing
sth
spent
是spend的过去式
初中阶段只要求掌握spend
...(in)

spend的主语是somebody
EP:I

my
homework.
I
spend
20
