present perfect VS past simple
present perfect--- 指啱啱做完, 或前排做完, 但句子入面無明確顯示時間,
如yesterday, last week咁, e.g. I have finished my homework.
呢一句, 無講幾時finish o既, 但總之已經finish咗, 所以用present perfect.
e.g. I have studied in this school since 2005. 呢句都用present perfect,
因為以前做緊o既嘢, 而家仲做緊(表示持續, 未斷) (以前05年開始讀,
而家都仲讀緊)
至於past tense, 非常咁簡單, 你可以放心。你只要知道句子係講過去o既
嘢就用past, 提示字有yesterday, last week, last year, on Friday, etc.


present perfect / past perfect
past perfect同present perfect容易混淆, 但其實只要記住past perfect係past,
就唔會記錯。past pefect tense同present perfect 一樣(功能), 只係已經過咗去,
例如講故事o既時候就會用。 e.g. (story) Lily had finished her homework.
