Please teacher tell me?

1.Why wait any longer when so far he hasn't appeared?

2.We have lots of time, why hurry?
(Yea technically not spousta use comma but instead semi--or separate)

3.When (or "If") he doesn't love you at all, why waste so much time thinking about him?

4.Why ("are you" or just "you") still sitting there, don't you know it's getting late?
(Technically tho Isak tween it needs semi or period as in 2)

4.Why still sitting there? when it's so late
(Yes many will reject this one, Im, but others say it's okay)

4.Why (are you) still sitting there? Don't you know it's getting late?

4.Why still sitting there, it's getting late
(Current practice often in such cases to eliminate the "?"

5.Why ask such a question, it sounds absurd?
(See 4 above )

6.Why be with such an annoying person when you don't like her?


Doubtless Con or one of the other excellent techs will elaborate

Why do I/you/we have to wait any longer when he hasn't appeared after so long?



We have a lot of time; why (do we have to) hurry?



Since he doesn't love you at all, why waste so much time thinking about him?



Why are you still here? Don't you know how late it is (getting)?



What ask such a question? It's absurd.



Why should you stay with such an annoying person when you don't even like her?

In every single sentence you wrongly used the -ing form of a verb. This is clearly an area you need to study more.

My initial reaction is that this quoted sentence is ungrammatical.

That's a bad start!

Oops, sorry . I did not notice the ESL designation...and thought I might be speaking to a student looking to have his/her homework done by us.

My apologies.

Your opening sentence needs lots of work.

Give it another try...see if you can fix it yourself.

If not, some of us will offer suggestions.

Thank you to you all for worthy replies.

It seems I have totally failed with using the -ing form in a sentence and have a lot more to learn about it.

By the way, as using Why + V-ing is ungrammatical, does it become grammatical if -ing is omitted, to read, such as, 'Why have to do sth' without pronoun being put between Why and Have?

'Why do I have to do that?'

Even without the gerund, you still need either a noun or pronoun in there. Here's a pretty good tutorial on gerunds and infinitives: http://www.englishpage.com/gerunds/

Really good site for me to learn more about gerund. Thank you.

No sweat. Hope it helps.
