1. 一般现在时和现在进行时
一般现在时常用于指经常性、习惯性的动作,往往带有长久的含义;而现在进行时则表示此刻或近一段时间正在进行的动作,往往带有暂时的含义。例如:
He lives in Shanghai. 他住在上海。(长久住在上海,但说话时不一定在上海)
He is living in Shanghai. 他现在住在上海。(暂时住在上海,但不一定长久住在上海)
—Bob must be very wealthy.
—Yes, he earns more in one day than I do in a week.

2. 一般过去时和过去进行时
一般过去时往往表示一个已经完成的动作或过去习惯性的动作;而过去进行时表示过去某时正在进行的动作,具有持续和未完成的含义。例如:
I was quickly getting used to that kind of life. 我正在迅速地适应那种生活。(还在适应中)
I quickly got used to that kind of life. 我已习惯那种生活了。(已经适应了)
He rang the bell six times. (谈论过去多次重复的动作或习惯性的动作用一般过去时)
My watch was going at 6:00 but now it has stopped.
当表示在一个历时较长的动作进行过程中发生了较短动作时,较长的动作用过去进行时表示,较短的动作用一般过去时表示。例如:
Linda was dancing, but when she saw me she stopped.
I broke a glass while I was cooking the dinner.

3. 一般过去时与现在完成时
二者所表示的动作均发生在过去。一般过去时仅指动作在过去发生了,对现在没有影响;现在完成时的动作虽发生在过去,但影响到现在。例如:

—I hear you have an experience in the Royal Air Force. Is that true?
—Yes. I served in the Royal Air Force for six years.(过去的经历)
Danny has worked hard for long to realize his dream and now he is popular.
如果有与现在时间没有联系的具体的表示过去的时间状语时,就要用一般过去时或过去进行时。例如:
I know a little bit about Italy as my wife and I went there several years ago.
—Have you found your pen yet?
—Yes. I found it when I emptied my drawer.

4. 一般过去时和过去完成时
二者参照的时间不同。一般过去时通常指相对于现在的过去;过去完成时指过去的过去。例如:

He said he had tried at least three times.(try在said这个过去的动作之前)

5. 现在完成时和现在完成进行时
二者区别不太明显,都表示从过去开始一直持续到现在的动作或状态,一般情况下可互换。例如:
He has lived here since the 1980s.
He has been living here since the 1980s.
现在完成时常常用来表示完成的概念,说明某一动作刚刚完成,或者谈论动作的结果。现在完成进行时则强调活动的延续性。例如:
I haven been reading your book. (I havent finished it yet.)
I have read your book.(I have fininshed reading it.)

6. will 和be going to
现在已有迹象表明将要发生某事或即将发生某种情况时用be going to。例如:
George is putting on weight. He is going to be quite fat.
Look at the black clouds. It is going to rain.
如果是事先考虑过的,即说话时刻之前已经考虑过的将要发生的事,要用be going to,如果不是事先考虑过的,即说话时刻才作出的决定,要用will表示,它多用于一方听到另一方的话后做出的反应。例如:
—I am catching the 7:00 train.
—So am I. I will give you a lift to the station.

7. 时态的一致性
一般现在时可在时间或条件状语从句中表示将来时间,此时不用将来时态。但宾语从句不受此限制。例如:
You wont succeed unless you work hard.
I think it is necessary for my son to have his mobile phone, for I sometimes want to make sure if he will come home for dinner.
主句为现在时,宾语从句可以用各种时态;主句为过去时,宾语从句用过去的各种时态。例如:
He told me that he would be taken to Beijing by his father.
