There could be many different reasons for that:
1) site navigation is unclear
2) you are getting traffic for unrelated topics and they didn't need your site
3) navigation could be broken
4) site does not work properly in all browsers
5) if you are selling a product or service your price point may be too high (or not high enough)

One tool you should look at for some language assistance is the Google translation [google.com], it may help when you hit a sentance that you can't fully understand.
But some questions need to be answered before I (or any other board member) can help you solve you problem:
Do you know where have your webmaster submitted your site?
Can your webmaster tell where people come to it from?
Do you use any other promotion methods? Link exchanges? Directories? Banners?
