"从大体上讲，这个问题分3部分"英语怎么说？

In general, the problem/issue can be addressed/approached in three aspects.

addressed/approached 都有解决的含义，用在这里是很合适的。

the problem/issue都有问题之意。这里不能用question

Generally speaking, this question can be divided into three parts

Generally speaking, this issure should be considered from three different aspects
从整体上讲，这个问题应该从3方面考虑

1.who
is
work
in
the
hospital?
2.who
is
a
tv
reporter?
这两个对画线部分提问，首先把is提前，没有的加上is。
因为回答的是人，所以，要加疑问词who。
3.miss
green
is
a
math
teacher.
这句是说：教数学的
所以我们就可以说，miss
green是一名数学老师。
