■觀念三：假設語氣


ex : If he ________ here next weekend, I will give him this as a birthday present.

(A) will come　(B) comes　(C) is coming　(D) has come

李捷這麼說：下週末雖然是未來時間，但因為屬於有可能發生的未來；還是得用現在簡單式代替未來式。所以本題必須選(B) comes。


※文法焦點：表示現在或未來有可能發生的事：if 所引導的條件子句須用現在簡單式代替未來式。








ex : If a man doesn't remain content with what he has, ill will befall him.

ex : If it rains tomorrow, we will put off our picnic.


※文法焦點：表示與現在事實相反的假設：假設法過去式（條件子句必須用過去式）








ex : Jay doesn’t know how much money I spent in buying this car; if he ever found out,

I am sure he'd never forgive me.


※文法焦點：表示與過去事實相反的假設：假設法過去完成式 [條件子句須用過去完成式]








ex : I would have bought some from the fruit stand if litchis had been in season.


※文法焦點：該是……的時候了：與現在事實相反的假設語氣








ex : It is ( about ) time you told us the truth, or we will be very angry with you. = It is ( about ) time for you to tell us the truth, or we will be very angry with you.


※文法焦點：表建議，請求，堅持等動詞後所接的子句常將助動詞should省略：








ex : The manager suggested that we (should ) adopt a different policy. (表主動)

ex : I desired that the action (should) not be postponed. (表被動)
