現(xiàn)在進行時的理解與用法：
?
一、如何理解
?
顧名思義，現(xiàn)在進行時就是指說話時正在進行的動作或發(fā)生的情況。如漢語說的“我在看書”“他在吃飯”“火車在行駛”“秘書在打字”等，在英語中都要用現(xiàn)在進行進來表達，因為它們所涉及的動作在說話的時刻都正在進行。
?
?
二、構(gòu)成與用法
?
現(xiàn)在進行時由“am / is / are + 現(xiàn)在分詞”構(gòu)成。如：
?
She is still sleeping. 她還在睡覺。
?
We are waiting for the rain to stop. 我們在等雨停。
?
They are playing quietly now. 他們在安靜地玩著。
?
過去完成時的用法：
?
(1) 某些動詞如intend / think / plan / expect / hope等的過去完成時表示主語未曾實現(xiàn)的愿望、希望或打算。如：
?
I had intended to come to see you last night, but someone called and I couldn’t get away. 我原打算昨晚來看你，但有人來訪，我拖不開身。
?
He had hoped to find a job soon.他本來希望很快找到工作。
?
I had meant to come, but something happened. 我本想來，但有事就沒有來。
?
(2)過去完成時用在hardly / scarcely…when…和no sooner…than 固定結(jié)構(gòu)中。如：
?
No sooner was the frost off the ground than the work began. 地上的霜一消散，人們就開始工作了。
?
Hardly had he arrived when she started complaining. 他剛一到, 她就開始抱怨起來。
?
(3) 過去完成時用于條件分句或wish / would rather等后面的that從句中，表示與過去事實相反的主觀愿望。如：
?
I would have met him, if I had come this morning. 今天早晨我來的話，就會見到他了。
?
I wish I had seen you yesterday. 我昨天見到你多好。
?
