I don"t like apples我不喜歡蘋果（否定）

2， 疑問語氣： What"s your name？你叫什麼名字？

Do you like apples?你喜歡蘋果？

3，祈使語氣： Open the door 開啟門

3， 虛擬語氣： If I were you, I would forgive her如果我是你，我將會原諒她。

虛擬語氣結構講解：

1， 與現在的事實相反：從句用過去式，主句用would/could/might/should/+動詞原形

例如；If I had time ，the classroom would be so clean 如果我有時間，教室將會更加乾淨。

2， 與過去的事實相反：主句用would/could/should/might/+have+ done , 從句中過去完成時

例如；If I had finished my homework ，I would have passed that test

如果當時我完成了我的做，我就能夠透過我的考試了。

3， 與將來的事實相反：主句用：should/could/would/might/+動詞原形，從句用should do （可能性最大），過去式（可能性一般）were to do （可能性最小）
