Question

初二英语问题，说明为什么选

Doing homework _____ me two hours yesterday.
A took B cost

Answer 1

A cost的主语是物或某种活动， 还可以表示“值”， 常见用法如下：(1)sth. costs (sb.) ＋金钱,某物花了（某人）多少钱。例：A new computer costs a lot of money. 买一台新电脑要花一大笔钱。(2) (doing) sth. costs (sb.) ＋时间,某物（做某事）花了（某人）多少时间。例：Remembering these new words cost him a lot of time. 他花了大量时间才记住了这些单词。

注意：cost的过去式及过去分词都是cost,并且不能用于被动句。

take后面常跟双宾语， 常见用法有以下几种：(1) It takes sb. ＋时间＋to do sth. 做某事花了某人多少时间。例：It took them three years to build this road. 他们用了三年时间修完了这条路。(2)doing sth. takes sb. ＋时间,做某事花了某人多少时间。例：Repairing this car took him the whole afternoon. 他花了一下午修车。

选B
解析：doing sth. cost sb. some time意思是做某事花费某人多少时间
而take一般都用于这个固定的搭配：It takes sb. some time/money to do sth.中文意思同上
