情態助動詞:表達不必須與禁止: don’t have to, must not

今天要說的還是情態助動詞,做建議的時候,我們這麼做吧!不如這樣做吧?算是簡單又清楚的,只是同樣的字,比方說 could 有好幾種用法,一個個用法看很清楚,有時候看到他出現的時候,卻會不知道用法是什麼或究竟該在什麼時候用。其實這些用法都很日常,多去注意聽一些用法,久了就會知道在什麼時候用。學過後仔細聽電視影集或電影裡面用到的時機,跟時態一樣,慢慢地就會有感覺知道在什麼時候需要用哪個字,不過需要花時間多練習,多聽多看多讀,盡量用出來,不要怕用錯,雖然用錯有時候意思會差很多。這就是語言啊!Ces’t la vie! (法語,但是英文也常用)這就是人生啊!週末愉快!
