Could you please tell me how to correct these 3 sentences ?

1 He said he was going to come at 5 pm. He can come at 5 just as he can come at 8pm. You never know.
2 He checks his mail box just like you check yours which is once every two days.
3 I'd date her just like/as you'd date him. They are both good looking.

Thank you
Hi alc24,
Oh, no! The dreaded like/as controversy. Actually, these sentences are pretty straightforward, i think.

Sentence 1 needs help. What you are trying to say is that he is just as likely to come at 8 as at 5, which is when he said he was coming.

If I were writing it, i would say: He said he was coming at 5, but he is just as likely to come at 8. You never know.

2. He checks his mailbox [note that mailbox is one word, not two] as you check yours, [note comma] which is every two days. [as is a conjunction here with the verb phrase, as you check yours]

3. I'd date her just as you'd date him. [a conjunction again--so don't use like].

As [not like!] you probably have noticed, like is more frequently used in casual speech. I think this is because it has a simpler, more relaxed feeling. But if you use like as a conjunction in place of as on a test or when talking to your teacher, you will most likely be penalized.

Thank you very much for your answers Trys.

One question:

For 1

Can you say: He's just as likely to come at 5 as at 8. You never know with him.

So basically you can't say my original sentence?

can you say this:
  • He can do comedies just as he can do action movies. He's a good actor.
Some say you can, but I'm not sure.

thank you
Hey, how come you are 'Anonymous' now?? When i first answered your question, you were alc24...

Yes, you can phrase it as you did above, although i would change it round to emphasize the possiblilty [or likelihood] that he will be late: He's as likely to come at 8 as 5. You just never know with him.

Your second sentence would be understandable, but it wouldn't be the way a native says it. i think it would sound better to say: He can do comedies as easily as he can do action movies. He's a versatile actor.

In conversation, you probably would not repeat the somewhat awkward as he can do and simply say: He can do comedies as easily as he does action movies. That rolls off the tongue better and says the same thing.
