时态是谓语动词通过自身的变化来表示动作发生的时间和所处状态的各种形式。也就是说时态是通过句子谓语动词的某种形式来体现的。今天我们复习六种：一般现在时，一般过去时，一般将来时，现在进行时，过去进行时，现在完成时。
一、一般现在时
表示主语的性格、能力、特征，以及经常性、习惯性的行为。主语是第三人称单数时，行为动词词尾加-s或-es, 其余人称用动词原形。连系动词be有am, is, are三种形式。have的第三人称单数形式是has。一般现在时常与always, sometimes, once a week, every day,on Sundays等时间状语连用。例如：
1. She goes to school by bus evey day.
她每天坐车去学校。
2. My mother always gets up very early every day.
我妈妈每天总是起床很早。
由when, until, as soon as引导的时间状语从句和由if, unless 引导的条件状语从句，要用一般现在时表将来。例如：
1. I’ll ring you up as soon as I get to Beijing.
我一到北京就给你打电话。
2. I’m going to see you if it doesn’t rain tomorrow.
如果明天不下雨，我就去看你。
二、一般过去时
表示过去的行为或状态，也可以表示过去经常性的行为或状态，谓语动词用过去式。动词be的过去式有was(第一、三人称单数)和were (其余人称)两种形式；动词have的过去式是had。一般过去时常与表示过去的时间状语连用，如：yesterday, last night (year / month, week ...), ... ago, in 2008等。例如：
1. He worked in this city in 2000.
2000年他在这个城市工作。
2. Mother bought a nice handbag last Sunday.
上星期天妈妈买了个好看的手提包。
三、一般将来时
表示将来的时间里发生的动作或存在的状态。谓语由
“be going to+动词原形”或“will (shall)+动词原形”构成，shall用于第一人称，will用于第二、三人称，现代英语中will可用于所有人称。一般将来时常与表示将来的时间状语连用，如：tomorrow, next year / month / week ..., this morning等。例如：
1. I shall (will) visit my uncle tomorrow afternoon.
我明天下午去拜访我叔叔。
2. Look at the black clouds. It is going to rain.
看那些乌云，要下雨了。
go, come, start, move, leave, arrive 等词可用进行时 态表示按计划将要发生的事情。
3. I'm arriving at my hometown in half an hour.
我将在半小时之内到达我家乡。
四、现在进行时
表示说话时或现阶段正在进行的动作或发生的事情。谓语由“be (am / is / are) + V-ing形式”构成。现在进行时常与now, these days等时间状语或提示词look, listen等连用。例如：
1. What are you doing now
现在你在做什么
2. Listen！Someone is singing in the next room.
听！有人在隔壁唱歌。
表感觉、态度、情感的动词，如：see, hear, feel, want, like, think等没有进行时。
五、过去进行时
表示过去某一时间正在发生的动作或存在的状态，谓语由“was (were) + V-ing形式”构成。常与this time yesterday, at six yesterday, when+从句等特定的过去时间状语连用。例如：
1. I was watching TV this time yesterday.
昨天这个时候我正在看电视。
2. I was shopping when you called me yesterday.
昨天你打电话的时候我正在购物。
六、现在完成时
现在完成时由“have/has + done”构成，使用情况有两种。
动作在说话之前就结束，对现在有影响。句中没有具体的时间状语。
1. He has gone to Fuzhou .

动作始于过去，持续到现在，也许还会持续下去。常与表示一段时间的短语或者so far, now, today, this week/month/ year 等时间状语连用。
