mba英語語法：時(shí)態(tài)
一、一般現(xiàn)在時(shí)
一般現(xiàn)在時(shí)通常表示習(xí)慣動作、一般狀態(tài)、客觀規(guī)律和永恒真理。如主語為第三人稱單數(shù), 動詞后需加s或es。
He always gets up late on Sundays.(習(xí)慣動作)
He lives on a lonely island in the Pacific Ocean.(一般狀態(tài))
The sun rises in the east and sets in the west. (客觀規(guī)律)
[提示]
在以等引導(dǎo)的時(shí)間狀語從句中, 或以if, unless等引導(dǎo)的條件狀語從句中, 通常用一般現(xiàn)在時(shí)代替一般將來時(shí)。
I’ll ring you as soon as he comes back. (as soon as, when, after一般現(xiàn)在時(shí)表將來時(shí)) You’ll succeed if you try you best. (一般現(xiàn)在時(shí)表將來時(shí))
二、現(xiàn)在進(jìn)行時(shí)
現(xiàn)在進(jìn)行時(shí)表示說話時(shí)正在進(jìn)行的動作, 也表示目前一段時(shí)間內(nèi)正在進(jìn)行崐的活動。表示后一種情況時(shí), 動作不一定正在進(jìn)行。
They are putting up the scaffolding.(說話時(shí)正在進(jìn)行的動作)
Steve is studying Chinese in Beijing. (目前一段時(shí)間內(nèi)正在進(jìn)行的活動)
[提示]
1. 并非所有動詞都有進(jìn)行時(shí), 有些表示狀態(tài)和感覺的動詞通常無進(jìn)行時(shí), 除非這類動詞的詞義發(fā)生變化。這類動詞有:be, love, like, hate, believe, think, feel, seem等。 Do you see anyone over there? (表示狀態(tài)和感覺的動詞通常無進(jìn)行時(shí))
Are you seeing someone off? (詞義發(fā)生變化)
2. 現(xiàn)在進(jìn)行時(shí)也可表示將來的動作: 它指按人們的計(jì)劃、安排將要發(fā)生的動作或指即將開始的動作。

The conference has lasted for five days. (已完成的動作)
He’s just bought an nuusual taxi. (剛剛完成的動作)

一般過去時(shí)表示過去某個(gè)特定時(shí)間發(fā)生且一下子就完成的動作, 也可表示過去習(xí)慣性的動作。一般過去時(shí)不強(qiáng)調(diào)動作對現(xiàn)在的影響, 只說明過去。
I had a word with Julia this morning. (一下子就完成的動作)
He smoked forty cigarettes a day until he gave up. (習(xí)慣性的動作)
[提示]

八、將來進(jìn)行時(shí)
