English is important in the modern world. It is spoken all over the world. But a few students don’t learn English well. So they want to drop English. I suggest that you shouldn’t give up English, because English is used in many countries as the first or second language. Most business letters are written in English. It is helpful for you to work in the future. If you don’t know English, you will fall behind others in future.
How can you learn English well? First, you should persevere. It’s true that English is sometimes really very difficult for us. But if you have a good method of learning, I think you will be good at it. Both English listening and speaking are the most difficult for almost every beginner. Sometimes, it seems impossible to learn. But I think if you do a lot of practice, you will make progress, you should speak more and listen more often. You’d better speak English with your classmates as often as possible not only in class but also out of class. I advise you to buy a radio, so you can listen to some English programmes over the radio. Then you will travel in the world of English.If you do that, you’ll be able to learn English well easily, and you’ll like English very much.
I hope all of you will become good at English step by step.

When facing a mirror, how do you feel? Proud? Satisfied? Or sad? In fact, most people look the most beautiful just when looking at themselves in the mirror. It is probably because everyone wishes to be flattered, especially by a “fair” mirror. That the reflections in the mirrors show their beauty makes them feel comfortable.
So a suggestion has been given: “Smile to a mirror when you feel lonely.” Of course, if you are really smiling to your heart, you will be glad to enjoy your look, even the spots on it, which are regarded as your own characters. Now, one’s look depends on one’s heart, though at the same time, the mirrors unfair. The spots, however, will not go away unless you clear them. Flattery is never true, it must prevent you from improving yourself. In the end, I would like to say: Let the mirror put its finger on your weak spot, then you may be the most beautiful in the fair life.
