是dp sth with sth还是do sth by sth如果不是是用什么其他的借词吗。还是有很多固定搭配或者其他因素？

英语是：use sth to do sth。
例如：
The disabled can use robot-arm to do some simple movements.
残疾人可以用机器手做一些简单的动作。

the best thing what is the best thing? the answer of different people will vary. everyone will have different answer. if you like something most,you will think it as the best thing. for example, if you like listening to music better than watching tv,you will think that the beautiful songs are the best things in the world,they are much better than all kinds of tv program. since every individual has different opinion about the best things, we should respect other's thoughts.even the thing you think is not so good,you still have to understand why others thought it's the best one.as for me,i think the freedom and happiness in the life is the best thing,although there's always sadness and failure in the living.
