Remembering words isn't very hard
Relax to do it . And sometimes when you suddenly remember one word ,you should make sure you can spell it easily and rightly although you do another thing at that time.Don't think that you can
remember later ,so you needn't to think out the word now,it's wrong.And in your life,you can say the things in English in you heart.If you don't know how to say a word or a sentence,ask your friends or don't forget the problem until you know it well.
There are many ways to study English well,but the most important to learning English is hard-working
You can pass the problem by yourself if you study harder and harder~!!!
