measure和weigh的，类似，用法？
measure和weigh都有三种词性：名词、及物动词、非及物动词
作名词时，measure意为
（1）措施 例：We should take some measures to solve this problem. 我们要采取一些措施解决这个问题。
（2）尺寸 例：She made the trousers to my measure. 她按照我的尺寸做了一条裤子。
（3）程度 例：The result, in a certain measure, depends on her decision. 从某种程度来说，结果取决于她的决定。
作名词时，weigh意为“权衡” 例：After our weigh, we give you another chance, 经过我们的权衡，决定再给你一次机会。
作为及物动词时，measure和weigh都有“权衡”的意思。例：You need to measure the quality and the quantity of the influence. 你要从“质”与“量”两方面权衡影响。
但measure指的是“测量、估量”，而weigh指的是“称……的重量”。例：
How to measure the length of that box 如何测量那个盒子的长度？
How to weigh that box 如何称那个盒子的重量？
同时，weigh还有“考虑”的意思。例：You can weigh this matter patiently and reply me 2 weeks later. 你可以耐心考虑这件事，两周后答复我。
作为不及物动词时，measure就只有“测量、估量”的意思，没有”权衡“的意思了。例：It is the only thing we can measure. 这是我们唯一能测量的。
作为不及物动词时，weigh意为
（1）重量为…… 例：How many pounds does the box weigh 这个盒子重量为多少磅？
（2）具有重要性 例：His words weighed heavily with the jury. 他的话对陪审团发生重要影响。
