中五生大概要識多少個生字??

I dont have the exact answer for you but if you could read an article, lets say, of a newspaper that you dont have to look at the dictionary for most of the words, I guess you are good enough. You have sufficient vocabularies to handle many day to day reading and conversation.

It is the way how I practice my English in my daily life. After some interesting conversation, I will try to play a mind game to translate it into English. When I come across a sentence in Chinese particularly, I will think how it would be like if I have to write it in English. Similarly, when I am writing a sentense in English, I will try many other ways to present the same idea using different sentense structures and different words. Make your learning interesting in your daily life is important.

Good luck.

講真要睇下你去到咩程度.同埋睇你想識咩字,口語上果d,定係書本果d.
其實唔需要花太多時間學深字.你留意下外國人日常既溝通,or睇戲,用字都唔深,易明.偶然只有1or 2個到.
你想識多d生字你首先要多用,就算學幾多都冇用.我對作文冇咩興趣,但我會成日上外國forum玩.我識字唔係太多,主要係日常口語既字,同埋,建議你用多dphrasal verbs,好用又easy,重有idioms,proverbs呢d都係成日用到
