英语的时态 1.一般现在时 2.现在进行时 3.现在完成时 4.现在完成进行时 5. 一般过去时 6. 过去完成时 的公
7.过去进行时 8.过去进行时 9.过去将来时 的公式
非常好的还给加分
英语时态分为：一般现在、一般过去、一般将来、过去将来时，以及这四者的进行时、完成时和完成进行时。
1.一般现在时
用法：
A) 表示现在发生的动作、情况、状态和特征。
B) 习惯用语。
C) 经常性、习惯性动作。
D) 客观事实和普遍真理。尤其要注意，如果前后文不是一般现在时，则无法保持 主句、从句时态一致。
E) 表示一个按规定、计划或安排要发生的动作，（仅限于某些表示“来、去、动 、停、开始、结束、继续”等的动词）可以与表示未来时间的状语搭配使用 。
常见的用法是：飞机、火车、轮船、汽车等定期定点运行的交通方式。
F) 在时间和条件状语从句里经常用一般现在（有时也用现在完成时）表示将来事情。
2. 现在进行时(be doing)
用法：
现在正在进行的动作。
3. 现在完成时(have done)
用法：
A) 表示动作到现在为止已经完成或刚刚完成。
B) 表示从过去某时刻开始，持续到现在的动作或情况，并且有可能会继续延续下去。此时经常用延续性动词。时间状语常用since加一个过去的时间点，或for加一段时间，或by加一个现在时间。
C) 表示发生在过去，但对现在仍有影响的动作或情况。通常用点动词，如：arrive, begin, find, give, lose等。
注意事项：
A) 现在完成时是联系过去和现在的纽带。现在完成时和过去时的区别在于：现在完成时强调动作的动态，或受动态的影响，是动态的结果，对现在有影响；过去时只表示过去的某个具体时间里发生的动作，与现在没有联系。
B) 因为含有for加一段时间或since加一个时间点这样的时间状语的完成时，有动态和延续性的特点，所以不能使用终端动词或瞬间动词。
C) 在"this is the first/ second/ third…… time that……"句型里要求用完成时。
D) 句型"It is/ has been……since"所使用的两种时态都正确。
E) 在"no sooner than"、"hardly/ scarcely ……when"、"before"、"prior to"等句型中，主句要求完成时。
4. 现在完成进行时(have been doing)
用法：
表示某一动作开始于过去某一时间，延续或重复地出现至今，或将继续延续至将来。
注意事项：
与现在完成时相比，现在完成进行时更强调：在从过去到现在的时间里，动作或状态一直持续或一直反复出现。
5. 一般过去时
用法：
A) 表示过去某个时间发生的动作或情况。
B) 表示过去习惯性动作。特别是由would/ used to do表达的句型，本身表示的 就是过去时。
C) 有时可代替一般现在时，表达一种婉转、客气、礼貌、商量的语气。
注意事项：
A) 注意时间状语的搭配。一般过去时的时间状语应该是表示过去某个时间的词或词组，
如：yesterday, last month, in 1999, two days ago等，绝对不可与recently, in the past 10 years, this month等连用，因为这样的时间状语都与现在有关系，应该用现在完成时或一般现在时。
B) used to do的否定形式和疑问形式很特别：你怎么写都正确。以否定形式为例：used not to do, didn't used to do, didn't use to do都对。
Used to do经常与 be used to doing sth/ sth结构进行对比。前者表示"过去常常或过去曾经"，要求加动词原形；后者表示"习惯于"，要求加名词或动名词。
6. 过去完成时(had done)
用法：
表示在过去的某个时间或动作以前已经发生的动作或已经存在的状态。就是我们常说的：表示"过去的过去的动作或状态"。
B) hasn't been hearing，现在完成进行时表示过去某时刻继续到现在或现在还在进行的动作，与题意不符。
C) hasn't heard，现在完成时表示从过去某一时刻到现在为止发生的动作。而题中的then只表示过去的某一时刻，不能表示现在时间。
注意事项：
“过去的过去”这种逻辑关系常通过上下文体现出来，而不一定受某个时间状语的限制。

⑴ 如果句子中的谓语动词是
be→am∕is∕are

Here comes the bus.
There they are .
2.现在进行时
【No. 1】现在进行时的构成
现在进行时由"be+v-ing"构成。be应为助动词，初学者最容易漏掉，它应与主语的人称和数保持一致。
【No. 2】现在进行时的应用
在实际运用时，现在进行时常用以下几种情况：
(1)当句子中有now时，常表示动作正在进行，这时要用现在进行时。如：
They are playing basketball now.现在他们正在打篮球。
(2)以look, listen开头的句子，提示我们动作正进行，这时要用现在进行时。如：
Listen！She is singing an English song.听，她正在唱英语歌。
(3)表示当前一段时间或现阶段正在进行的动作，且此时有this week, these days等时间状语，这时常用现在进行时。如：
We are making model planes these days.这些天我们在做飞机模型。
(4)描述图片中的人物的动作，也为了表达更生动。此时也常用现在进行时。如：

一般疑问句：Be(am, is, are) +主语+现在分词+其它？

对现在进行时的特殊疑问句的回答，它不可以用Yes或No直接作答，要根据实际情况回答。
3.现在完成时
主语+have/has+done+sth.
done为过去分词
例如 I have been to Shanghai
我已经去过上海了
She has finished homework

现在完成进行时(Present perfect continuous)基本表达式（I have been doing ）/（have/has + been +p.p.） I/ we/ you/ they have been doing sth. he/ she/ it has been doing sth. （一）表示从过去某时开始一直持续到现在的动作，并且还将持续下去。 The Chinese have been making paper for two thousand years. 中国有2000年的造纸历史。（动作还将继续下去） I have been learning English since three years. 自从三年前以来我一直在学英语。（动作还将继续下去） （二）表示在说话时刻之前到现在正在进行的动作。 We have been waiting for you for half an hour. 我们已经等你半个钟头了(人还没到，如同在电话里说的，还会继续等) （三）有些现在完成进行时的句子等同于现在完成时的句子。 They have been living in this city for ten years.

2.sb is/are doing sth
3.sb has/have done sth
4.sb has/have being done sth
5.sb did sth
6.sb had done sth,从句里出现的多。
7.8 sb was/were doing sth
9.sb would do sth
10. 给你添个“一般将来时”sb will do sth
