displacement和replacement的区别？
displacement和replacement的区别？
displacement是移位的意思，而replacement则是代替的意思，区别可以从以下例子看出：
As he is not fit for this match, he has been displacement, now we have to find replacement for this match. 由于他不适合这场比赛，他已经被移开，现在我们必须为这场比赛寻找替补。
安卓手机中的google服务是干什么的，怎么会自动使用那么多流量？
我在用Gmail. Maps,联系人同步，G ，Play，Fit，Google Now等，从方便程度讲，不考虑墙的因素(全天候24小时fq)，真的很方便很智能，但真的很费电，也很费流量。所以工作的时候都会把手机同步功能关闭，把玩的时候会随手打开！
