英文聽力及其他

Answer to your question about listening, learning new words (vocabularies) is practice more.

Practice makes perfect = the more you practise, the better you will be.

Work hard, not just think, practise from today or this miniute.

-listening more English Channel on Radio or English song,
-watch the English channel TV
-write a few setences daily or start writing diary
-read more books, magazine or newspaper in English, - read a story book every few days and or at least one book per week.
-check the meaning of every single word you don't understand in the dictionary or on the internet.
-write down all the vocabularies in a notebook so you can revise them whenever you like.

If you follow the said suggestion, your English will be improved rapidly in months

有何方法訓練出良好的英語聽力, 能夠聽到如CNN,BBC等新聞報導員講既"正常英語"?
邊聽邊看它的字幕。

另外,英文生字有咩方法記?(點變做長期記憶)
只有用。會用它就是你的。

最後, 我仲有1年就DSE,而我英文係1,2左右程度,如果我而家先發力溫英文,可否升至4甚至係5,若能,有什麼高效率溫習方法?
Of course, English is not hard at all especially when you are living in HK with so many helps available. Just spend more time on reading, writing, listening, talking and you will be surely fine.
