before, while and after a tornado

[dorax]

There are certain things you can do before, while and after a tornado.
Is the word ''while'' correct?

 

[emsr2d2]

No. You need "during" there.

 

[dorax]

Describe the problems refugees face in their homeland, while on the go, in the hosting country.
Here in this sentence is ''while'' correct?

 

[5jj]

Yes, but 'while travelling/fleeing/escaping' would be far more natural.

 

[dorax]

"on the go" is used as an adverb in the sentence above?
Can we say that "while" is used before adverbs or gerunds but not before nouns?

 

[emsr2d2]

If you use "while", you need a verb somewhere.

You can do things during a tornado.
You can do things while a tornado is happening.

Describe the problems refugees face in their homeland, while on the go, in the hosting country.

This sentence needs some correction. I don't understand it. Are you listing three situations in which refugees face problems? Do you mean this?:

Describe the problems refugees face when in their homeland, while on the go, and when in the hosting country.

What do you mean by 'while on the go'?

 

[dorax]

Yes, three situations: problems they face during their stay in their hometown, during their journey to another country and during their stay in a hosting country.

 

[jutfrank]

I see. Well, on the go doesn't obviously mean 'during their journey to another country'. I'd use a different phrase.

 

[dorax]

Such as?

 

[emsr2d2]

How about "... during their flight to a safe third country"?
