out of 与 of 的区别 last for 65 out of the past 90 years last for 65 of the past 90 years

题目

out of 与 of 的区别 last for 65 out of the past 90 years last for 65 of the past 90 years
last for 65 out of the past 90 years
last for 65 of the past 90 years
这两句 有无区别
那麽为何 five of my friends 可以

答案

第二句是不正确的!因为OF 表示所属关系,90years从逻辑上不能拥有65years!
只能说90years包含65years.所以,如果要表达90years里面的65years,要用OUT OF !
例如,在满分100分的考试里,你取得了90分,你要说：90 out of 100!
