英语翻译：要求

1. 用require没问题 可以说 working with machines is required/needed； working with machines is a requirement/ a need； you are required/need to work/dealing with machines; 甚至是 you have to work with machines. 看是什么语境了。

2. look (it) up in a dictionary. / refer to a dictionary

3.个人认为用divide 和 kind搭配不太好， 我建议说：
the work falls into two categories. 或简单一些
there are two kinds/types of work.

要求,最简单的可说ask sb. to do sth.
there are two kinds of job
one is...and anther is...

require可以
jobs are divided into two kinds强调divide，也就是分这个动作。如果你强调的是工作，可以说there are 2 kinds of jobs或者 jobs of 2 kinds
one..... the other.....

1.可以用require.译为you are required to communicate with machine.
2.look up in the dictionary.
3.there are two kinds of jobs. one is..., and the other is...

可以的~~
have sb. do
比较好
