Hello madina!
 
Don't worry. My students often have the same problem - but they translate into Chinese! It's a perfectly normal stage in learning a language. It will disappear with practice. To help you get a feel for how we say things in English, make sure you use some of our exercises and materials for listening and reading, like our Elementary English podcast, as well as doing grammar exercises.
 
Hope that helps!

Hi:
The Learn English Team.
I am learning the grammar. And now, I am confused.
Could you please show me the difference between the past/present simple and the past/present tense?
Thank you.

Hi The LearnEnglish Team!
I've been studying English since I was in grade school. I came to the UK nine years ago, went to school and improved my English even more. However, I'm still confused about some aspects of the language. Like if you use the phrase "must have heard" in a sentence to make a deduction or a logical conclusion, what then is the inverse or negative of this? "Musn't have heard" doesn't sound grammatical. Do we use "can't have heard" in this instance? Also, how do you ask the question to verify that somebody "must have heard" something? 
Thanks.
