Dear english trainers,

Could you help me distinguish the use of "could and "can besides could indicates past happenings? What's the difference of below sentences?

1) Don't worry I could do it
2) Don't worry I can do it

Thanks in advance.

Best regards,

Hi everyone,

I am wondering how to ask a question. As you can see, I do post a question sucessfully. Here is the example, http://www.english-test.net/forum/ftopic28745.html. But in the following test, I didn't find out the button or link "Do have you a question?". Here is another example. http://www.english-test.net/esl/learn/english/grammar/ei020/esl-test.php . I only see the link "Click here for Explanation." indeed. I want to know if this forum supports this function for ALL of the questions. Thanks a lot.

Maggie^^

Hi Maggie,

You will find the "Do you have a question" or "Click for her for explanation" links only in the tests, not on the forum. Once you are on the forum, you can ask a new question the way you have done before. I mean, you have already posted 210 messages on the forum, so you do know how to use the forum, don't you?
