do not 同 not

do , will, can

佢地都係一個詞式既表達詞

首先講左簡單少少既will 同can 先
will , 佢本身係用黎指示將來式既指示詞(幾乎係肯定會行動既)
e.g. someone will do something
Yan will go to Citysuper today.
恩今日將會去citysuper
另外, will 可以作noun用, 解作願望

Can, 佢本身係指示一件事既可能性係可行既意思, 並沒有表示會不會做, 只表示能不能做到
Yan can go to citysuper today
恩今日可以去citysuper
另外can可以作名詞用, 解作罐
<-----------------我是分隔線-------------------------->
最後do 既用法比較覆雜, 佢可以係一個時態指示詞
e.g. Yan did like swimming before, but she likes shopping now.
本來前面恩以前喜歡游泳的like(喜歡)應該用過去式, 不過由於已經用了指示詞do (did)所以, 後面動詞的時態就忽略了
另外, do 可作做的意思
