As you _______ the hotel, you will see a lake.

A. Approach

B. Are approaching

C. Will approach

D. Would approach

I honestly don't understand. The answer sheet says that since there's the word "as" here, the answer is "are approaching". Can you explain it a bit further? I just don't get it. "approach" seems equally correct to me. And I didn't eliminate the other 2 answers because although they seem less sensible to me, I still don't know why they would be incorrect. They just seem weird to me.

  • Would you please provide a link to the book, if it's possible? As a learner: "as" is a conjunction there which means "when something is happening". There is no strict rule that we should use "as" with present progressive or progressive aspect. The present progressive only conveys "during the period that you are approaching ( a short ongoing event ) you will see a lake".

1 Answer 1


You grammar manual is blatantly wrong and should be shunned. The correct answer is:

As you approach the hotel, you will see a lake.

The present simple here works similar to other clauses of indefinite time, e.g.

When you enter the building you will see a picture on the left.

  • I think "are approaching" is correct, too. Isn't it?

  • @Cardinal, not in this context. You may search for it in GoogleBooks. Jul 6, 2017 at 9:36
  • I don't think that kind of searching a whole sentence is a good way to judge about a sentence.

  • @Cardinal, the search I linked works well to show the very usage in which you are interested. It is not a full sentence. Jul 6, 2017 at 18:02
  • Fine, does this have anything to do with that future clause? For instance, let's consider "As you are approaching the hotel, call me to guid you to my place." Is that wrong? I know it's very common in past tense, for example, : "Just as she was leaving the room, all the lights went off"
