IT - SINCE/THAT ?

Hi Lechnitzky;

These two are the most natural:
I have been working here for 4 years.
It's been 4 years since I started working here.

OK thanks, I know these are the most natural. But if one of my students writes any of the sentences above which one(s) should I accept?

Lechnitzky MagdiI have been working here for 4 years.

This is correct, but it is better style to write out small numbers in words: "four years".

Lechnitzky MagdiIt is 4 years that I have been working here.

This one doesn't look quite so good.

Lechnitzky MagdiIt is 4 years since I ha

In Texas we'd say, 'been there 4 years'. It's short, sweet and to the point. Plus, it only took 4 words to say as opposed to 8 or 9. Then again, it would depend on who you were addressing. And I always use meant. I'm sure either is acceptable. It's the difference between it's and its that need to be correct in script/text. I've been here all my life and I still ***** it up sometimes.

And an English teacher would mark the sentence wrong.

At least you got that one correct.

Thanks I understood how to use didn't and doesn't

Its for years...since is used when mentioning a particular time. For eg. I've been living here since 20011.

here is the difference with singulr example look
There is n't a chair in the class.
There is no chair in the class.
the meaning is the same ,but the structure is different . as if to say ,when you use no . you do not use the article a/an before the singular noun.
in case of plural example look:
There are n't any chairs in the class.
There are no chairs in the class .

Science fiction - it's way too far in the future for me to imagine.
