例如：Did you see him today?今天你看见他了吗？
巧用英语时态表，掌握英语谓语形式 一、英语时态名称的记忆 二、英语时态形式的记忆：（以动词work为例） 可以分两个步骤记忆： 1、一般现在时： work（当主语是第三人称单数时，谓语动词也要用第三人称单数形式。） 现在进行时： be + working （be随主语人称和数的变化而变化。） 现在完成时： have + worked （have随主语人称和数的变化而变化，worked 是work的过去分词。） 这三种基本时态形式位于时态表的中心位置，是必须首先记住的。其它形式可推导而出。
2、记住了上面三种时态的形式后，可以设想把时间提前至过去，这三种时态的形式就相应地左移一格成为一般过去时：worked （worked是work的过去式）；过去进行时was / were + working；过去完成时had + worked （worked是work 的过去分词）。 把时间错后至将来，这三种时态的形式也就相应地右移一格成为 一般将来时： shall / will + work； 将来进行时： shall / will + be working； 将来完成时： shall / will + have worked。（shall仅用于主语是第一人称时，will可用于主语是任何人称时。）当然，根据shall / will 的用法要求，紧随其后的动词或助动词要用原形形式。 简而言之，把这三种现在时态形式左移变成三种过去时态形式，只需把第一个动词变成过去式即可（一般现在时谓语只有一个动词，也可把它看成为第一个动词）。与此类似，过去将来时的变化是在一般将来时的基础上把第一个动词变成过去式。把这三种现在时态形式右移变成三种将来时态形式，只需在前面加一助动词shall / will （紧随其后的动词或助动词用原形形式）即可。 三、英语被动语态形式的记忆（以动词ask为例）
1）五种句型 1.基本句型一： S V （主＋谓） 2.基本句型二： S V P （主＋谓＋表） 3.基本句型三： S V O （主＋谓＋宾） 4.基本句型四： S V o O （主＋谓＋间宾＋直宾） 5.基本句型五; S V O C （主＋谓＋宾＋宾补） 2）八大时态 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, on Sundays, 3.基本结构：动词原形（如主语为第三人称单数，动词上要加（e）S） 4.否定形式：am/is/are+not;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. 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。 2.时间状语：ago, yesterday, the day before yesterday, last week(year, night, month…), in 1989, just n ow, at the age of 5, one day, long long ago, once upon a time, etc. 3.基本结构：be动词；行为动词 4.否定形式：was/were+not;在行为动词前加didn't，同时还原行为动词。 5.一般疑问句：was或were放于句首；用助动词do的过去式did 提问，同时还原行为动词。 6.例句：She often came to help us in those days. I didn't know you were so busy. 三、现在进行时： 1.概念：表示现阶段或说话时正在进行的动作及行为。 2.时间状语：now, at this time, these days, etc. 3.基本结构：am/is/are+doing 4.否定形式：am/is/are+not+doing. 5.一般疑问句：把be动词放于句首。 6.例句： How are you feeling today? He is doing well in his lessons. 四、过去进行时：

初中英语八大时态总结 一、一般现在时 具体情况（主要用于下面几情况） 1) 描述当前时间内经常出现、反复发生的动作或存在的状态。 在这种情景中，句子常带有表示频率的时间状语：always , everyday , often , once a week (month , year , etc.) , sometimes , seldom , usually等等，以表示句中的动作或状态是习惯性的、经常性的。例如： They raise ducks as a sideline .他们以养鸭为副业。 It seldom rains here .这儿很少下雨。 2）仅为了描述状态、性质、特征、能力等等。 这里的目的是为了"描述现阶段的动作或状态"，其重点"不是强调动作发生的时间、或进行的状态"。例如： He can speak five foreign languages .他能说五种外语。 That is a beautiful city .那是座美丽的城市。 3) 陈述客观事实、客观真理。 顾名思义，客观的情况是"没有时间概念"的；也"不会在意动作进行的状态"。例如： The sun rises in the east .日出东方。 4) 根据英文语法规定，当主句的谓语动词是一般将来时，那么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。 *【用于一般现在时的副词，除了上面提到的一些表示频率的以外，常见的还有：now, today , nowadays等等】 二、一般过去时 具体情况（主要用于下面几情况） 1.主要是用来描述在过去某个时候发生的动作或存在的状态。它也可以用来表示在过去某段时间里经常发生的习惯性动作。 例：I was very thin in my childhood. 2.一般过去时由谓语动词的过去式表示，也就是说动词词末要加-ed（除不规则动词外）。常和一般过去时连用的过去时间状语有：last night (week ,month , year , century , etc.) , yesterday , the day before yesterday , yesterday morning ( afternoon , evening ) , in 1999 , two hours ago ( one week ago , tree years ago , …)等等。 例：Did you meet yesterday? He left just now. 3.使用一般过去时，在某种意义上说就是要强调动作或状态发生或存在于过去的某个时候。"过去"的时间概念有两层意思：一是指"现在某个时间"以前的时间；二是指"说话、写文章的那个时间点"以前的时间 He got his driving license last month. 他上个月拿到了驾照。
