Question

关于英语中by 的意思
she is taller than me by about 1.5 inches.
这里面的by 是指什么意思?谢谢.
还有一道：she want to be thinner
是不是只要前面是 want to be 的句型
后面都用比较级?谢谢.

Answer 1

by（表程度）相差 　　He missed the bus by three minutes.
want to be 一般做“想成为”解,后面是名词.后面是adj(形容词)的话,一般是要用比较级.
例：We want peace , we want freedom , we want security we want to be stronger , we want freedom to gain .
我们渴望和平,我们渴望自由,我们渴望安全,我们渴望强大,我们渴望赢得自由.
但也要看情况：
例：1、In the same way , we now use this expression to referto anything -not only clothing want to be sure is right for our needs .
同样的道理,我们现在用这个习语表示所有我们需要试一试才知道是否适合的事物,不再限于衣服.
