height

No. We would usually say He is [just] as tall as I am.

Gus' answer is correct. We might also say, "He and I are (of) the same height."

Thank to Gus and Phlip.
when I read an article written in English or an English book I understand the content throughly. But when it come to write a paragraph I stuck in third or fourth sentence. Why it happens? Why I cann't write a good paragraph in english? Why I cann't find the mistake out in my sentence that seem to me incorret. Lastly how can I improve my writing abilities?

sundarnazLastly how can I improve my writing abilities?

The same way you "get to Carnegie Hall" - pratice, practice, practice. And always have someone to correct your errors. Here, of course, is a good place for that.
One mistake you have made above is the lack of inversion for questions. You wrote Why I can't write.. It should be Why can't

Here, of course, is a good place for that.
As far as I concern, cheaking someone's written work is a pantience of job. Are you ready to do this tedious work?
And Thanks for correction.
