许多同学共同的烦恼背古诗、背课文,背了好几遍似乎已经记住了,但第二天上课时却都忘记了!在英语学习上花的时间最多,又听录音又默写的,但背过的单词,过了两天就忘光了!有些数学题,平时都做过,可是一考试却觉得很陌生,怎么都想不起来了! Many students common troubles back poems, back text, back several times seems to have remembered, but the next day when they have forgotten! Spend the most time in English learning, but also listen to the recording and dictation, but the back Spent words, after two days forgotten! Some math problems, usually done, but a test but very strange, how can not remember!
