If you want to become a fluent English speaker you should take some advice. There are four skills in learning English. They are reading,listening,speaking,and writing. The most important thing you must remember is that if you want to improve your speaking and writing skills,you should first master the skills of reading and listening. Read as much as you can. But your reading must be active. It means that you must think about the meaning of the sentence,the meaning of the unfamiliar(不熟悉)words,etc. There is no need for you to pay much attention to grammars or try to understand all the unfamiliar words you come across,but the fact that you see them for the first time and recognize them whenever you see them,for example,in other passages or books,is enough. It would be better to prepare yourself a notebook so you can write down the important words or sentences in it. As for listening,there are two choices:besides reading,you can listen every day for about 30 minutes. You can only pay attention to your reading and become skillful at your reading,then you can catch up on your listening. Since you have lots of inputs in your mind,you can easily guess what the speaker is going to say. This never means that you should not practice listening. For listening you can listen to cartoons or some movies that are specially made for children.Their languages are easy. Or if you are good at listening,you can listen to VOA or BBC programs every day. Again the thing to remember is being active in listening and preferably taking some notes. If you follow these pieces of advice,your speaking and writing will improve quickly,and you can be a fluent English speaker one day. 43.
