a couple of ,a piece of ,a pair of ,a bit of 的区别
a couple of ,a piece of ,a pair of ,a bit of 的区别
前俩个就是看意思就好了哦
1 a piece of 一块（张,片,只）
2.a bit of 一点
3.a couple of 和 a pair of
a pair of 虽然在数量上表示“二”.但是一定是配对的东西（一对,一双）.
如：a pair of shoes （一双鞋）,a pair of glasses （一副眼镜）等.
而a couple of 不一定是配对的东西.下面的实例表现了a pair of与a couple of 在词义上的差别：
Not every couple is a pair.成双未必成对.
