一般现在时的用法
1) 表示经常的或习惯性的动作，常与表示频度的副词连用。常用的频度副词有：always、often、usually、seldom、never。频度副词在句中通常放在行为动词之前，系动词、助动词之后。
例如: He often goes swimming in summer.他夏天经常游泳。
I usually leave home for school at 7 every morning. 每天早上我七点离开家。
2)表示现在的状态。
例如：My father is at work.He is very busy. 我父亲在工作，他很忙。

3)表示主语具备的性格、特征和能力等。
例如：All my family love football .我全家人都喜欢足球。
My sister is always ready to help others . 我妹妹总是乐于助人。
Ann writes good English but does not speak well. 安英语写得不错，讲的可不行。
4)表示客观真理，客观存在，自然现象。
例如：The earth moves around the sun. 地球绕太阳转动。
Shanghai lies in the east of China. 上海位于中国东部。
5)表示按计划或安排好的，或将要发生的动作，可用一般现在时表将来。但只限于start,begin,leave,go,come,arrive,return,take place等。
例如：The train leaves at six tomorrow morning. 火车明天上午六点开。
He comes back tonight. 他今晚回来。
6)在复合句中，当主句是一般将来时，时间或条件状语从句的谓语动词只能用一般现在时来表示将来要发生的动作。
例如：I'll tell him the news when he comes back. 他回来时，我将告诉他这个消息。
If you take the job , they will talk with you in greater details.

英语的动词时态这一语法现象与我们母语的语法差别较大，学起来也较乏味。如何教学这些语法，从而使学生更好、更有效地掌握它们，是经常困扰教师的问题。笔者在教学实践中进行了努力的尝试和探索，并依据信息加工的学习理论，总结出较为行之有效的“三元”教学法：从“标志”信息输入着眼，经过“概念”思维加工，达成“结构”形式输出，从而使师生摆脱枯燥的时态教学，掌握动词时态的规律，形成有效的语法教学策略。
一、从“概念.结构.标志”三个方面把握动词时态
“概念.结构.标志”三个方面是学习一种时态所必须把握的，三者相互联系，相互制约，共同表述一个完整的时态含义。“概念”清楚地说明了一种时态的用法。对于概念的把握一定要全面、准确，表述严密，如对于一般现在时的用法，不能只表述为“表示经常性或习?
下面列举两种时态进行说明。
（一）一般现在时
1.概念：一般现在时的基本用法有四种。(1)表示现在的状况，如Mr. Green has two children. (2)表示主语所具备的性格或能力，如Ann enjoys listening to the radio. Miss White speaks Chinese very well. (3)表示经常性、习惯性或反复出现的动作或状态，如I usually rest on Sundays. Mr. Brown always gets up early. LiLei goes to see Uncle Wang once a month.
(4)表示客观事实和普遍真理，如It never snows in Australia in December. Light travels faster than sound.
2.结构：一般现在时的结构在一般情况下用动词原形，当主语是第三人称单数时，谓语动词也要相应变成单数形式，其否定式、疑问式要加助动词do或does。例如：Miss Gao teaches us English. Does your mother work in a factory?
3.标志：一般现在时常与下列表示频率的副词或短语连用：always, usually, often, sometimes, seldom, never, twice a week, on Sundays等。
一、一般现在时
1.概念：经常、反复发生的动作或行为及现在的某种状况。
2.时间状语：Always, usually, often, sometimes, every week (day, year, month…), once a week(day, year, month…), on Sund ays,
3.基本结构：动词原形（如主语为第三人称单数，动词上要改为第三人称单数形式）
4.否定形式：主语+am/is/are +not+其他; 此时态的谓语动词若为行为动词，则在其前加don't, 如主语为第三人称单数，则用doesn't，同时还原行为动词。
5.一般疑问句：把be动词放于句首；用助动词do提问，如主语为第三人称单数，则用does，同时，还原行为动词。
6.例句：. It seldom snows here.
He is always ready to help others.
Action speaks louder than words..
[编辑本段]二、一般过去时
1.概念：过去某个时间里发生的动作或状态；过去习惯性、经常性的动作、行为。

4.例子：I have been sitting here for an hour.

[编辑本段]十一、一般过去时与现在完成时的转换
在现在完成时中，延续性动词能与表示一段时间的状语连用，瞬间动词却不能。但是，可用别的表达方式：①瞬间动词用于“一段时间+ ago”的一般过去时的句型中；②瞬间动词可改成与之相对应的延续性动词及短语，与一段时间连用；③瞬间动词用于“It is + 一段时间+ since + 一般过去时”的句型中，表示“自从……以来有……时间”的意思，主句一般用it is来代替It has been;④瞬间动词用于“Some time has passed since + 一般过去时”的句型中。请看：
A. He joined the League two years ago.
B. He has been in the League for two years.
C. It is two years since he joined the League.
D. Two years has passed since he joined the League.
[编辑本段]十二、一般现在时与现在进行时的转换
在一般现在时中，at加上名词表示“处于某种状态”，如at work（在工作）, at school（上学、上课）等。此短语可与进行时态转换。请看：
Peter is at work, but Mike is at play.
Peter is working, but Mike is playing.
[编辑本段]十三、现在进行时与一般将来时的转换
在现在进行时态中go, come, leave, start, arrive等动词常与表示将来的时间状语连用表示将要发生的动作。如：I am coming, Mum! 意为“我就来，妈妈！”请看：
The train is leaving soon.
The train will leave soon.
（二）现在完成时
1.概念：基本用法有两种。(1)表示过去发生的动作对现在造成的影响或结果。(2)表示从过去已经开始，持续到现在的动作或状态，常与表示一段时间的状语连用。
2.结构：助动词have(has)＋动词的过去分词。
3.标志：用法(1)常与下列词语连用：already, yet, just, ever, never, before, recently等；用法(2)常与“since＋时间点”或“for＋时间段”所构成的表示一段时间的状语连用，也可与包括“现在”在内的表示一段时间的状语连用，如this morning, these days等。
其他几种时态不再一一列举。在平时的教学中，只要我们从上述三个方面去把握动词时态，学生就会逐渐发现其规律，做到有章可循，主动地学习，从而变以教师为主体的讲语法
为以学生为主体的学语法，收到事半功倍的效果。
二、要善于进行各种时态的用法比较
学习了几种时态以后，就容易出现混淆、错用的情况，这就要求我们要不断地将一些时态加以比较，以便能够更好地把握其本质。其实，动词时态的比较也是以“概念.结构.标志”三元为依据比较的。试看下面几种时态的比较。
（一）一般过去时与现在完成时的用法比较
1.一般过去时只单纯表示过去的动作或状态，和现在不发生联系，它可以和确定的表示过去的时间状语连用；而现在完成时既涉及过去又联系现在，但它强调的是现在的情况，所以它不能和确定的表示过去的时间状语连用。试比较：I have posted the letter（说明现在信不在这里）。I posted the letter yesterday（只说明昨天寄信这一事实）。
2.有些时间状语（标志），如this morning, tonight等，既可用于一般过去时，也可用于现在完成时，但所表示的意义有所不同。用于现在完成时的表示“现在”在内，而用于一般过去时则与“现在”无关。例如：I have read the book this May（讲话时仍是五月）。I read the book this May（讲话时五月已过）。
（二）一般过去时与过去完成时的用法比较
1.一般过去时表示过去某时间发生的动作或存在的状态；而过去完成时则表示在过去某一时间或动作之前已完成的动作或状态，其标志是“过去的过去”。当强调过去某一动作发生在过去另一动作之前时，常用此时态。例如：The film had already begun when I reached the theatre.
2.一般过去时与过去完成时都可以和确定的表示过去的时间状语连用，但侧重点有所不同。试比较：They had done the work at five o’clock. They did the work at five o’clock.第一句说明工作在五点钟已完成，并未说明是什么时候完成的；第二句说明工作是在五点钟做的。
3.在带有before或after引导的时间状语从句的复合句中，由于主、从句动作发生的先后顺序已非常明确，所以可用一般过去时代替过去完成时，如The train had left before I got to the station.也可以说：The train left before I got to the station.
其他时态的比较，如一般现在时与现在进行时，一般过去时与过去进行时的用法比较不再列举。时态的混合使用是以掌握好每一种时态的用法以及各时态的比较用法为基础的，在中学阶段使用较少，在此不做详谈。
三、注意时态与时间不一致的特殊情况
如前所述，判断时态要从“标志”（时间状语）着眼，这是一般规律。但有些情况下，时态与时间（标志）并不一致，在教学中应引起足够的重视，做到灵活使用，可视之为“特殊标志”。
1.一些表示来往动作的动词（动向动词）常用进行时表示将来时，常见的这类动词有arrive, come, go, leave, set off, start等、例如：The Browns are leaving for Paris next month.
2.一般现在时有时可以表示预定的近期将发生的动作或状态，也可用来表示说话时正在进行的动作。例如：Are you free tomorrow? The train starts at 7:50 in the evening. Here comes the bus! There goes the bell!
3.一般过去时可以表示目前非真实的情况或不能实现的愿望（即虚拟语气）。例如：I wish
I could fly to the moon by spaceship. It’s high time you went home. If I were you, I would go with him.
4.在含有状语从句的复合句中，当主句是将来时态或是祈使句时，状语从句应用一般现在时或现在完成时代替一般将来时，用一般过去时代替过去将来时。例如：I will go to town if it doesn’t rain tomorrow. He said he would come to see us if he had time. Please tell him
about it as soon as he comes back. Are you going to play with us when you have finished your homework?
5.在含有宾语从句的复合句中，主从句动词时态有如下不一致情况。
(1)当宾语从句表示科学真理、客观事实、格言或其他不受时间影响、限制的客观存在的事物时，如：Long ago people didn’t know that the earth moves round the sun. She told hers on that practice makes perfect.
(2)当宾语从句用来解释、表达科技内容时，如：The teacher told us that the attraction of the earth for all bodies is called gravity.
(3)当宾语从句表示一种反复出现或目前习惯性动作时，如：He said he does morning exercises everyday.
(4)当宾语从句中谓语动词的动作在转述时仍在继续，或表示现在时刻仍存在的状态时，如：LiLei said his father is attending a meeting in Shanghai. She told me the other day that she is only seventeen.
6.其他从句，如比较状语从句、定语从句等不受主句时态的影响，应根据实际需要，选择适当的时态。例如：It was colder yesterday than it is today. Last night I read the book which you are reading now.
对于这些特殊情况，在平时的教学中，应特别注意。其实，我们也可以把上述情况视为一种特殊的“标志”，进而判断相应的时态形式。

一般疑问句和特殊疑问句
1、一般疑问句的定义：对于只用Yes 或No来回答的疑问句我们叫一般疑问句.
2、特殊疑问句的定义：对句子当中某一部分内容的提问我们要用特殊疑问句，比如问时间用
When或者what time 问地点用where...
这里我们主要学习特殊疑问句的用法.
3、特殊问句的用法：特殊问句是由疑问词+ 一般疑问句组成，那么在我们使用特殊问句时，要先选好疑问词，特殊疑问词有很多，需要长期积累。
例如：I want to go to sleep now. 如果对go to sleep 提问，那么我们应该问你想要做什么，首先应选择疑问词what ,再将剩下的句子变为一般问句即可.
What do you want to do ?

一般现在时的基本用 法及练习
一般现在时的用法 一般现在时表示人、事、物现在的状况和特点或表示经常性、习惯性的动作，句中常有always、often、usually等时间状语。现在时还可用于表达格言、科学事实、客观真理和至今不变的客观事实。 注意： 主语是任何一个单数名词或者是第三人称单数，谓语动词要进行必要的变化。特别提一点：不可数名词也算作单数处理。 动词第三人称单数的变化规则及发音规律 动词原形变第三人称单数的规则与发音规律同名词单数变复数大致相同，请认真观察。 1、大多数动词在词尾加“S”,在清辅音后发音为[s]，在浊辅音及元音后发音为[z]。 如：stop－stops [s] make－makes [s] read－reads [z] play－plays [z] 2、以辅音字母加“y”结尾的，要先将“y”变为“i”，然后在加“es”读[iz] 如：fly－flies [z]； carry－carries [z] study－studies [z]; worry－worries 3、以“s, x, ch, sh”结尾的，在词尾加“e s”，发音为[iz] 如： teach－teaches [iz]; watch－watches [iz] 4、以“o”结尾的动词，加“es”，读[z] 如：go－goes [z] do－does [z] 句型 I.疑问
1.对于谓语动词或助动词是 be、have、can/may/must 等，将这些词移到主语前面。 Are you students？Yes, we are. / No, we aren't.你们是一名学生吗？是的。我们是一名学生。/不，我们不是。 Is Jane in the classroom? Yes, she is. / No, she isn't.简在这个教室里面吗？是的，她在。/不，她不在。 Does the house have two rooms? Yes, it does / No, it doesn't.这栋房子里面有两个房间吗？是的/不，不是。 Is there any water in the glass? Yes, there is. / No, there isn't.杯子里面有水吗？是的，有。/不，没有。 Can you swim? Yes, I can. / No, I can't.你会游泳吗？是的，我会。/不，我不会。 2.谓语动词是实义动词，方法是在主语前加助动词do或does构成，句中动词要改用原型动词。do用于第一人称和名词复数，does用于第三人称单数和名词单数或不可数名词。 Do you know it？Yes, I do. / No, I don't.你知道这个吗？是的，我知道/不，我不知道。Does she have a pen？Yes, she does. / No, she doesn't.[have 这里是实义动词]她有一个钢笔吗？ Do they play basketball after school? Yes, they do. / No, they don't.他们放学后打篮球吗？II. 否定 1. 对于谓语动词或助动词是 be、have、can/may/must 等，后面直接加not。 I am not at college.我不在上大学。 Mr. Wang isn't 50 years old.王先生不是50岁。 The Jacksons have not two sons.贾克森没有两个儿子。 You may not go now.你现在不可能去了。
