花时间/钱的"花"英语单词是什么?我只知道spend ,cost还有,顺便说下那个是修饰时间,那个是修饰钱,那个既可花时间又可花钱顺便问下 :(1)plenty of(2)a lot of 后面加可数n.还是不可数名词,还是都可以这是2个问题,OK?

take

cost.take
It costed me two hours to do my homework.

need.

spend ,cost，take
可数不可数都可以

spend 后既可接时间又可接钱,如：
I spend two hours on my homework．或 I spend two hours
in doing homework．
I spend 100 dollars on the coat．
cost后只能接钱,如：
It costs me much money to buy the books.
take 后只接时间,如：
It takes her 3 hours to finish her homework.
注意cost 和 take 不能用人做主语．
plenty of后只接不可数名词,a lot of后既接可数又能接不可数名词．

waste 两者都可以
1，2后面都可以加
