如果是想通过自学，逐步提高英语应用水平，可以（以下是我从国外网站找到，自己中文翻译的学习方法）：
How To Learn English? 如何学英语？
Here are some tips which may help you to master the English Language! 以下是一些小窍门，能帮你快速掌握英语！
1. Speak without Fear 不要怕，大声说出来
The biggest problem most people face in learning a new language is their own fear. They worry that they won’t say things correctly or that they will look stupid so they don’t talk at all. Don’t do this. The fastest way to learn anything is to do it -again and again until you get it right. Like anything, learning English requires practice. Don’t let a little fear stop you from getting what you want.
学语言，最大的障碍就是没信心。不要怕说错，最快能掌握英语的方法，就是多说，不断重复再重复，直到完全掌握。
2. Use all of your Resources 尽可能利用各种资源
Even if you study English at a language school it doesn’t mean you can’t learn outside of class. Using as many different sources, methods and tools as possible, will allow you to learn faster. There are many different ways you can improve your English, so don’t limit yourself to only one or two. The internet is a fantastic resource for virtually anything, but for the language learner it's perfect.
语言学校不是唯一可以学英语的地方，你可以通过不同的途径和方法，这能让你进步更快。
3. Surround Yourself with English 浸泡到英语环境中
The absolute best way to learn English is to surround yourself with it. Take notes in English, put English books around your room, listen to English language radio broadcasts, watch English news, movies and television. Speak English with your friends whenever you can. The more English material that you have around you, the faster you will learn and the more likely it is that you will begin “thinking in English.” .
浸泡绝对是最好的学习方式，自己营造英语环境，比如放英文广播，看英语新闻、电影电视等，和朋友们用英语交流等，渐渐养成用英语思考的习惯。
4. Listen to Native Speakers as Much as Possible 尽可能多和英语为母语的人接触
There are some good English teachers that have had to learn English as a second language before they could teach it. However, there are several reasons why many of the best schools prefer to hire native English speakers. One of the reasons is that native speakers have a natural flow to their speech that students of English should try to imitate. The closer ESL / EFL students can get to this rhythm or flow, the more convincing and comfortable they will become.
英语为母语的人，发音等跟以英语为第二语言的人肯定不同啊，学语言就是个模仿的过程，当然要越地道越好的人学啦
5. Watch English Films and Television 看英文电影电视
This is not only a fun way to learn but it is also very effective. By watching English films (especially those with English subtitles) you can expand your vocabulary and hear the flow of speech from the actors. If you listen to the news you can also hear different accents.
这是一个既有效有有乐趣的法子了。看电影可以增加词汇量，可以模仿发音，听新闻可以熟悉不同地方人说英语的口音。
6. Listen to English Music 听英文歌
Music can be a very effective method of learning English. In fact, it is often used as a way of improving comprehension. The best way to learn though, is to get the lyrics (words) to the songs you are listening to and try to read them as the artist sings. There are several good internet sites where one can find the words for most songs. This way you can practice your listening and reading at the same time. And if you like to sing, fine.
听英文歌也是一个寓教于乐的好办法，可以提高理解力。优美的歌词跟诗一样，可以同时锻炼听力和阅读能力，如果你也爱唱，那更好了。
7. Study As Often As Possible! 学习和练习的越多越好
Only by studying things like grammar and vocabulary and doing exercises, can you really improve your knowledge of any language.
要学习语法、提高词汇量、多做练习，英语才能越学越好。
8. Do Exercises and Take Tests 做练习题，不时做个测验
Many people think that exercises and tests aren't much fun. However, by completing exercises and taking tests you can really improve your English. One of the best reasons for doing lots of exercises and tests is that they give you a benchmark to compare your future results with. Often, it is by comparing your score on a test you took yesterday with one you took a month or six months ago that you realize just how much you have learned. If you never test yourself, you will never know how much you are progressing. Start now by doing some of the many exercises and tests on this site, and return in a few days to see what you've learned. Keep doing this and you really will make some progress with English.
做练习题和测验可能听起来很无趣，但是这确实是非常有帮助的方法。通过测验，你可以知道自己与刚学英语的时候、上个月、六个月以前，进步了多少，可以随时知道自己的进展，是非常好的促进学习的方法。
9. Record Yourself 给自己录音
Nobody likes to hear their own voice on tape but like tests, it is good to compare your tapes from time to time. You may be so impressed with the progress you are making that you may not mind the sound of your voice as much.
给自己录音，比较现在和以前相比的区别和进步。
10.Listen to English 听英语
By this, we mean, speak on the phone or listen to radio broadcasts, audiobooks or CDs in English. This is different than watching the television or films because you can’t see the person that is speaking to you. Many learners of English say that speaking on the phone is one of the most difficult things that they do and the only way to improve is to practice.
在电话中讲英语、听广播、听CD，与电视里看英语电影是不一样的，因为你看不见，所以光听英语（比如讲电话）时更加困难，也就是提高和练习的好机会。

Have fun!
