现在过去将来时态练习
过去将来如今 第一篇
Ⅰ、一般现在时的用法：
1、 经常性或习惯性的动作，常与表示频度的时间状语连用。如：always，usually，often，
sometimes，every week（day, year, month…）, once a week, on Sundays,etc.练习：
I _______(leave) home for school at 7every morning.
He_______(clean) the room every day.
Her mother often_______(go) shopping once a mouth.
Li gang usually _______(play) basketball on Sunday.
We always_______(learn) from each other.
They _______(go) to school on foot every day.
2、客观真理，客观存在，科学事实等。练习：
The earth _______(move) around the sun.
Shanghai _______(lie) in the east of China.
The sun_______(rise) in the east and _______(set) in the west.
Water _______(boil) at 100℃. Three plus(加) two _______(make) five.
3、表示现在的特征或状态。
Ann _______(write) good English but does not_______(speak) well.
He _______(work) hard.
We _______(be) students.
一般现在时的否定：①am/is/are+not;②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。
将陈述句变为一般疑问句：①把be动词放于句首；②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。
She does the housework every day. （改为否定句）
She _______ _______ the housework every day.
Kate does morning exercises every day. （改为一般疑问句）
_______ Kate _______ morning exercises every day？
插入讲解：单数句与复数句之间的互变
转化时，名词和动词的人称和数，人称代词、物主代词、指示代词的人称和数都要作相应的变化。如：
15. That is my book.
_______ _______ _______ _______.
16. She is his student.
_______ _______ _______ _______.
Ⅱ、一般过去时的用法
1）在确定的过去时间里所发生的动作或存在的状态。例如：时间状语有：ago, yesterday, the day before yesterday, last week(year, night, month…), in 1989, just now, at the age of 5, one day, long long ago, once upon a time, etc.练习：
We_______(see) a film yesterday.
He _______(be) a doctor 3 years ago.
2）表示在过去一段时间内，经常性或习惯性的动作。例如：
When I was a child, I often ______(play) football in the street.
我是个孩子的时候，常在马路上踢足球。
四种谓语动词的表现形式
① be动词的过去式was、were.
例如：She was a teacher five years ago. 她五年前是一名教师。 ② 行为动词的过去式，分为规则动词和不规则动词两种。规则动词的过去式的构成遵循
以下四个规则：1）直接在动词后加ed，例如：help-helped; want-wanted等； 2）以不发音的字母e结尾时，去掉e加ed (即直接加d) , 例如：like-liked; use-used等；3）以辅音字母y结尾时，把y变成i再加ed, 例如：carry-carried; study-studied等；4）以重读闭音节结尾，双写最后一个辅音字母再加ed, 例如：stop-stopped; shop-shopped等。而不规则动词的过去式则需要我们认真下工夫去记了，例如：go-went; come-came; buy-bought等。
③ 连系动词的过去式。 例如：become-became She became angry. 她生气了。
④ 情态动词的过去式+动词原形。
例如：I could swim at the age of five. 我五岁时就会游泳了。
请写出下列动词的过去式。
二 训练第二关：生病的句子能奈我何？
请在仔细诊断每个句子后，把正确的句子写在横线上。

2. She was buy a dress last week. _________________________________

4.-Did you have a good trip ? -No, I didn’t.____________________________
5. We didn’t flew kites last month. ______________________________
He returned the book to the library this morning. （改为否定句）
He _______ _______ the book to the library this morning.
Ann returned the book to the library yesterday. （改为一般疑问句）
_______ Ann _______ the book to the library yesterday？
否定形式：①was/were+not;②在行为动词前加didn't，同时还原行为动词。
一般疑问句：①was或were放于句首；②用助动词do的过去式did 提问，同时还原行为动词。
Ⅲ、一般将来时
一般将来时表示将来某个时间要发生的动作或者存在的状态。通常与表示将来的时间状语连用，如tomorrow, the day after tomorrow, next year, next month, next week, in 100 years等。 be going to do （动词原形）结构：表示打算、准备做的事情或者肯定要发生的事情。如：It is going to rain.
will do 结构表示将来的用法：
1. 表示预见
Do you think it will rain?
You will feel better after a good rest.
2. 表示意图
I will borrow a book from our school library tomorrow.
What will she do tomorrow?
基本构成如下：
一般疑问句构成：
（1）will+主语+do…? Will Sarah come to visit me next Sunday?
（2）there be 结构的一般疑问句：Will there + be …?
Will there be fewer trees? Yes, there will. / No, there won’t
否定句构成：will + not （won’t）+do
Sarah won’t come to visit me next Sunday.
特殊疑问句构成：
特殊疑问词＋will＋主语＋…？What will Sarah do next Sunday?

Tom ________（is / are）a good student. 汤姆是个好学生。
They often ________（plays / play）football on the playground. 他们经常在操场上踢足球。
2. 意义一致原则：指主语形式上为单数，但意义为复数，因此谓语动词用复数形式；或主语形式上为复数,但表示单数意义，这是谓语动词用单数形式。
My family ________（is / are）having lunch now. 我们一家人现在正吃午饭。
Twenty dollars ________（is / are）too expensive for the book. 这本书20美元太贵了。
3. 就近一致原则：指谓语动词用单数形式还是用复数形式，取决于最靠近它的主语。例如： Not only the teacher but also his students ________（like / likes）playing football. 不仅老师喜欢踢足球，而且他的学生也喜欢踢足球。
There ________（is / are）a pen and some books on the desk. 课桌上有一支钢笔和一些书。 单数名词(代词)，不可数名词作主语时，谓语用单数形式；复数名词(代词)作主语，谓语用复数形式。
The desk ________（is / are）Tom’s. 这张桌子是汤姆的。
Some water ________（is / are）in the bottle. 一些水在瓶子里。

未来、现在和过去
时间的步伐有三种：未来姗姗来迟，现在像箭一样飞逝，过去永远静止。——题记
生命的时钟随着岁月的飞逝“嘀嗒、嘀嗒„„”的响着，请静下来想想：直到现在，我们向往些什么？拥有着什么？失掉了什么？我们向往着未来，拥有着现在，失掉了过去。
每一天都有一个明天。面对茫然的未来，眼前是一片充满雾气的世界，这时的我们是该木然等待又或是拼搏未来？趁着这雾气还未消失，我们可以去努力争取，碌碌无为的人总是人生的失败者。有一天，待这雾气散去，努力过的人所见之处便是晴天，朱熹说：“少年易学老难成，一寸光阴不可轻。”是啊！趁着现在正值年少，我们应当为未来有所拼搏，我们应当用自己的青春与热情去拥抱明天，让每一个明天都是晴天。
每一天都是今天。今朝易逝，昨日难回，莫等那时间从手中溜走时才恍然大悟，即便再次用力抓紧，也只是徒劳。每一天都是唯一的，它永远不可能无穷无尽，就如一指流沙般，来得易，失得快。“一寸光阴一寸金，寸金难买寸光阴”，我们所拥有的每一个今天都是一笔笔巨大的财富，它可以任由我们随意挥霍，但当我们用尽时，再想用金钱将它买回，那也只是妄想罢了。让我们迈开步伐，抓紧脚步，紧跟上时间的进程，走稳每一个今天！
每一天都要成为过去。“人生天地之间，如白驹过隙，忽然而已。”时间总是逝得很快，那已然逝去的岁月，被封在每个人心中，只可回忆，不可触及。有的人因回想起曾经的快乐而快乐，有的人因回忆起曾经的忧伤而忧伤，但这又是为了什么呢？为了再也回不去的过去吗？那只会使你一度黯然失神。当你回望起过去时，身边的时间正在一步步溜走，这很有意义吗？当无数个今天成为昨天，而无数个昨天成为过去，我们不应当止步不前！
当未来成为了现在，现在成为了过去，过去成为了历史，岁月如流水般一去不复回。望着时间的穿梭交错，我们无法止住时间，唯一能做的，便是在这有限的生命里做出不平凡的事。
现在时﹑过去时﹑将来时﹑过去将来时
过去将来如今 第五篇
一般过去时
一般过去时：简单地说是表示过去发生的动作或存在的状态。我们首先来看看一般现在时的构成。
一般现在时的构成：
a. be动词过去式的句式。否定句是在was/were后面加not，was not (wasn't)/were not (weren't)。一般疑问句是把was / were提前并放到句首，要求首字母要大写。
b.实义动词过去式的句式。
①肯定式：主语+动词过去式+其它。
如：They had a good time yesterday.
②否定式：主语+did not(didn't)+动词原形+其它。如：They didn't watch TV last night. ③一般疑问句：Did+主语+动词原形+其它？肯定回答：Yes，主语+did.否定回答：No，主语+didn't.
如：Did they have a meeting two days ago? Yes，they did. / No，they didn't.
④特殊疑问句：特殊疑问词+did+主语+动词原形+其它？如：What time did you finish your homework?
知道了一般现在时的构成，我们在看看在什么情况下，我们才能使用它。 一般过去时的用法：
①一般过去时的基本用法
a)表示过去某个特定时间发生的动作或存在的状态。
He suddenly fell ill yesterday.
昨天他突然生病了。
The engine stopped because the fuel was used up.
发动机因燃料用光而停机了。
b)表示过去经常发生的动作或存在的状态。
I wrote home once a week at college.
我上大学时每周给家里写一封信。
He was already in the habit of reading widely in his boyhood.
他童年时就养成了广泛阅读的习惯。
一般过去时的时间状语表示一般过去时的时间状语有：a moment ago(刚才)，yesterday morning，last night/ week，the day before yesterday(前天)，just now(刚才)等。
我们在前面讲过一般现在时，那一般现在时和一般过去时有什么不同点呢？下面我们来看看两者之间的区别。
一般现在时和一般过去时的比较
一般现在时要和现在的时间相联系，而一般过去时和说话的“现在”没有联系。 His father is a film director.
他父亲是电影导演。 (他现在还是)
His father was a film director.
他父亲曾是电影导演。 (他现在不是)
How do you like the novel?
你觉得这部小说怎么样？ (还在看小说)
How did you like the novel?
你觉得这部小说怎么样？ (已看完小说)
讲了关于一般现在时的这么多方面，还有一个非常重要的知识我们必须学会，就是动词的一般过去式。因为英语的不同时态主要是通过动词和时间状语来实现的。
动词一般过去式的构成
a.规则动词过去式的变化可速记为直、去、双、改四字诀。
①一般情况下在动词原形后直接加-ed。如：wanted，played。
②以不发音的字母e结尾的动词，去掉e再加-ed。如：hoped，lived。 ③重读闭音节单词需双写最后一个辅音字母再加-ed。如：stopped。 ④以辅音字母+y结尾的动词变y为i，再加-ed。如：studied，worried。 b.不规则动词变化，要逐一熟记。be动词过去式有两种形式，主语是第一、三人称单数形式使用was，其他人称用were
常见错误如下:
一 把动词变成过去式易出错
例: 1 They stoped (stop) talking just now.
2 They plaied (play) football yesterday.
答案: 1 stopped 2 played
解析:我们可以记住下面的口诀:"动词变成过去式,双写规律要牢记;y前若是辅音字,y变i加-ed;y前若是元音字,只须直接加-ed."
二忘记把动词变成过去式
例: I fly (fly) kites on the afternoon of Sunday.
答案: flew
解析:我们可以记住下面的口诀:"一般过去时态里,过去形式莫忘记".
