假装不在上海
、在老师讲新课之前大概了解一下老师上课要讲什么，预习的时候不懂的知识点用笔标记出来，上课的时候认真听就能做到事半功倍的效果。2、跟着老师的思路走，老师每天布置的作业，自己也要认真独立的去完成，不会的可以问学习好的同学，也可以去问老师。3、准备错题本，养成记录错题的好习惯，做错的题目在记录到错题本的同时，思考题目涉及的知识点和做错的原因，然后每天进行大量的计算练习。

Dear Editors, I have been reading your newspaper for many years with great enthusiasm and interest.Regarding the issue of disposable plastic bags, it is my view that limiting the use of such bags is of the utmost significance . To crack this hard nut,I would like to propose several practical recommendations as follows.First and foremost,it is imperative for us to ban the free use of disposable plastic bags. In addition, we should develop possible alternatives to replace them,such as paper or cloth bags. Last but not least, plastic bags should be offered at a much higher price in department stores or supermarkets. I hope you will find the above proposals constructive and I would like discuss this matter in further detail.Your prompt attention to my suggestions would be highly appreciated. Yours sincerely, Li Ming
