現在進行時的結搆

現在進行時的結搆：現在進行時由“am / is / are + 現在分詞”搆成。如：

I'm studying at Yu Cai Senior Middle school. 我在育才中學讀書。

He is writing on the desk. 他再課桌上寫字。

They are talking about their visiting the Great Wall. 他們在談論遊長城的事情。

動詞現在分詞的搆成方法：

(1) 一般在動詞後加-ing。如：say—saying, play—playing, think—thinking, study—studying, teach —teaching, blow—blowing, build—building.

(2) 動詞若以-e結尾, 則去e再加-ing。如：love—loving, make—making, guide—guiding, date—dating.

(3) 在以單短元音的重讀閉音節結尾，且末尾衹有一個輔音字母的動詞後，雙寫最後一個輔音字母，再加-ing。如：begin—beginning, regret—regretting, plan—planning, ban — banning.

(4) 在以ie結尾的動詞後，改ie爲y，再加-ing。如：lie—lying, die—dying, tie—tying.

(5) 在以-c[k] 結尾的動詞後加-king。如：picnic—picnicking, panic—panicking.
