How to improve your English in full detail (my experience) The Third EditionTo be good at English is not particularly easy but not terribly hard Before you start to learn sentences, or new words, the first and also the most important step is the "pronunciation" To pronounce perfectly you should buy a tape to assist you to learn and This is the fundamental step to learn English, ignore or pay no attention to this step; you will not learn proper English and you will find the later steps more and more If you are solid and accurate in pronunciation, you will find the later steps much easier and you will stand firmly on the right After mastering the pronunciation perfectly, it is the time to accumulate new words and useful Of course start from the simplest words like “hello, hi, you, me, he, him, his, her”, and expressions like “how are you, how old are you, how do you do”, It is essential to write the words on a piece of paper so that you remember them Actually everyone had done these at his/her primary *************Now let me tell you how I learnt English in C *******************Speaking:In China, you won't have enough chances to speak E What I did was in the morning I got up early and read aloud the texts in the The initial aim was to achieve the same speed as the tape, and then being able to read aloud the texts with the same style as the English announcer in the By doing this, it helps you to consolidate your pronunciation and Listening:Nowadays it is much easier to learn English in China because you can watch some TV channels in E The more channels in English the better because you can choose your preferred programmes and it helps you to learn English with interests of your own, hence ideal for listening and expression/words Writing:It is also very useful to write On writing diaries, it is not useful if you just write it without the care of grammar and When you finish you should always read your diaries again to check for errors and refine your sentences ( remove repetitive words, use better expressions, and sort out the structure of the sentences)Reading:It is also very important to read story books in English, starting from thin ones with not many new Read as many thin books as you possibly Little by Little you will want to read thicker books, and your reading ability will get even Putting four elements together:I have to emphasise that when you do all these reading, listening, writing and speaking; you should join them together as a whole, apply the new words you learn from watching TV, reading books to your writing and The enhancement of learning comes from getting hold of the possible opportunities to speak English (in China or abroad):In China, you should try to go to local English corner to practise your oral E If you are abroad then you should make a lot of English or international friends so you always have the opportunity to speak EOn Spoken English, attitude is very You need to be very keen and you must not be Never be afraid to make Always think that a talk in English with some one will help you You can think in this way: since my parents have paid so much to support me to study abroad, the money is partly spent on the international environment for learning English; therefore I ought to try my best to take every opportunity to practise my E My English has risen to a higher level in the last 2 years, because I talk in English most of the Having some international friends is particularly useful Summing up the activities:I have also been watching TV The real improvement lies in staying with international friends long enough and watching a lot of TV such as news, football, dramas, documentaries Writing diaries also helps me to remember good words, good expressions and practise sentence *****Now, I have finished talking about how to learn and improve General EIt is the time to switch to "Your Major in English" *******************************Knowing general English on its own is not going to be sufficient for most Skills are as important as mastering another General English helps people to communicate with each other in their Technical English helps you to take on challenges to change the world for the highest, to earn money for your living for the Some people who have a degree in English go abroad to learn something different but heavily based on the language such as Media study, Journalist, History, Education or even a bit more technical like Finance, Business Administration or EIt is extremely useful to know more because there are so many words in English and they appear differently to each For people whose second language is English, will find it difficult to guess the meaning of a new For sure, it is not possible to know Pick a major first and put all your effort on that major, in the end you will have a rich vocabulary of that Difficulties on learning Technical English:To master technical English in your area of study, there are two difficulties to 1, the language, because it is not your first language, you need to remember the terms, knowing how to pronounce it and spell 2, surely you need to understand the terms in a technical No matter what field, it is going to be the same; the two difficulties above must be Here I take Physics as an example (note that whatever field you are looking into is going to be similar):The term "momentum" is basically the product of the mass of the object and the velocity it Obviously, you need to understand mass and velocity as If you understand mass and velocity, then you get the explanation of the term "momentum" in physics, then you are most likely to understand the word and use it properly in the technical world of P From this example, you can see how to understand a technical word in a technical fashion: you need to understand the very fundamental knowledge of a field to be able to understand more complex terminologies or Before learning technical English in your field of study, I have a good recommendation to save your time:To understand technical knowledge in your first language (Chinese), then you might not have the second What it left to overcome is just the first difficulty (the language), hence the effort required is I can give you an example of my own:When I was learning chemistry at A-level, I had already learnt inorganic chemistry at the equivalent level in China, so I had no difficulty whatsoever in learning inorganic chemistry in the UK in EBut I had not learnt organic chemistry in China, and I was struggling significantly in learning organic chemistry in the UK due to dual ************OK, I have finished talking about how to improve your technical ENow i will talk about IT (Information Technology), why is this important?
