Writing

治標唔治本o既方法我就廢事講喇, 以下係我o既個人心得:

Remember that learning a language is a gradual process - it does not happen overnight.
Define your learning objectives early: What do you want to learn and why?
Make learning a habit. Try to learn something every day. It is much better to study (or read, or listen to English news, etc.) 10 minutes each day than to study for 2 hours once a week.
Remember to make learning a habit! If you study each day for 10 minutes English will be constantly in your head. If you study once a week, English will not be as present in your mind.
Choose your materials well. You will need reading, grammar, writing, speaking and listening materials
Vary your learning routine. It is best to do different things each day to help keep the various relationships between each area active. In other words, don't just study grammar.
Find friends to study and speak with. Learning English together can be very encouraging.
Choose listening and reading materials that relate to what you are interested in. Being interested in the subject will make learning more enjoyable - thus more effective.
Relate grammar to practical usage. Grammar by itself does not help you USE the language. You should practice what you are learning by employing it actively.
Move your mouth! Understanding something doesn't mean the muscles of your mouth can produce the sounds. Practice speaking what you are learning aloud. It may seem strange, but it is very effective.
Be patient with yourself. Remember learning is a process - speaking a language well takes time. It is not a computer that is either on or off!
Communicate! There is nothing like communicating in English and being successful. Grammar exercises are good - having your friend on the other side of the world understand your email is fantastic!
Use the Internet. The Internet is the most exciting, unlimited English resource that anyone could imagine and it is right at your finger tips.

Tips:
Remember that English learning is a Process
Be patient with yourself.
Practice, practice, practice

i'll i made many mistakes in sentence.
我唔肯定你所指ge mistake係唔係 grammar，但其實學英文／提高英文水平，都係傳統方法最受用，例如睇英文書．．．睇英文書可以俾你學多D Vocab.同 Phrase，仲可以學埋外國作家ge寫作手法
如果你係寫 Essay，就睇多 D Samples，睇下人地點樣表達，睇下人地ge寫作同表達手法。
其實係你「睇」ge同時，你會不知不覺中學緊 grammar，不過如果你問我，我會覺得學 grammar ge最好方法係做練習。可能你會覺得自己做練習ge時候好似好幼稚咁，但係你肯退一步去打好基本根底，會令你寫作ge時候少好多 mistakes.
仲有一個方法就係做 Proofreading ge練習，係捉人地錯處ge時候，就會學到如何避免犯相同錯誤。
