It takes sb. some time to do sth. 意为“花费某人……时间来做某事”。
spend 的主语必须是人，而spend …on sth. 意为“买某物花了……钱”。spend +时间+(in) doing意为“花费多少时间来做某事”。可以与it takes sb. some time to do sth. 来进行句型转换。
pay 的主语必须是人，而“花钱买某物”为pay … for。Language points 百分数“用基数+ percent”表示：
50％ fifty percent 百分之五十
3％ three percent 百分之三
0.12％ zero point one two percent
百分之零点一二
这里的percent前半部per表示“每一”，cent这一后半部分表示“百”，所以百分之几中percent不用复数形式。百分比英语表示法Language pointsDo you think the students at No. 5 are healthy?
