During work?working?

___, you should follow proper office procedures.

A.During working
B.While to work
C.During you work
D.While working

The answer is D(While working).
I worder why the answer A is incorrect from the textbook which says the anwser A (During working) should be revised into During work, then it is correct.

Why option A(working) has to be revised into work, both are nouns, aren’t they?

While working the THE correct answer…

Excuse me, I can’t catch the point what you are talking about.

Hi Eric,

‘During’ is a preposition and needs to be attached to a noun as in - during the day, during the winter, during the holidays and so on. If you attach it to the word ‘working’, this doesn’t have any meaning because it isn’t clear what the verbal form ‘working’ refers to.

Hi Alan,
Well, so I just think prepositions like before and after, both can be attached to gerunds ,and why during this preposition can’t be used as that way.

Or even if prepositions like before and after can not be attached to gerunds?

Hi Eric,

Good point. When you use for example ‘after working’ on its own, you would then have to relate that to a a subject to make clear who is doing the working as in - After working for three hours, Charlie went home to eat.

Reply to you, clear point very clear.

So when sentence includes gerund, most of time it happens at front or rear clauses which is to help reader or listener make it clear what the point is, isn’t it?

If the anwser above is,—>Yes, it is,and then thank you a lot Alan.

Hi Eric,

I think I follow what you mean. The main point is that a gerund has to relate to a subject within the sentence. It doesn’t matter which part of the sentence it is in.

Hi Alan,

Thank you for your kindly help, from now on I can fling the problems of preposition away, I hope so.

Eric

Hi Eric,
