Do you come tomorrow? 代 替 He returns home next Sunday. 将来一般时,说 明,主语是第三人称单数且为陈述语气时，一般现在时的动词（除be 和have外）词尾要加“-s”或“-es”。 “真理”以及“习惯性动作”，因为所表现的观念是“永恒”以及“经常如此”，所以不考虑时间或完成的问题，而一律用一般现在时。 表示“习惯性的动作”常与下列副词连用： Occasionally, every , always, usually,often,sometimes , seldom ,frequently。 以一般现在时代替一般将来时的用法如下： Go,come,start,leave,arrive等动词和表示未来时间的副词连用时。 在表示时间或条件的状语从句的动词，用一般现在时代替一般将来时，其句型是：If 主语+Will+V +主语+V(-s), When 祈使句 此类状语从句通常有下列连此引导： 表示时间：when, while, before, after, till(=untill), as soon as, by the time(=when/before) 表示条件：if,unless,in case(=if),现在进行时 动词形态am/is/are+V-ing 用 法 例 句 现在正在 He is writing a letter at present. 进行或继续 It is raining now. 的动作、状态 John is doing his assignment right now.

It has been raining since last night.,现在完 动词形态 成进行时 have/has been+V-ing 用 法 例 句 We have been studying English for three years. 继 续 He has been reading since this morning. We have been waiting for him all afternoon. 说 明 本时态是用来叙述“从过去某时开始,以致继续到目前的动作”.其特点在强调“动作的继续”性质.但也有“可能已经中止”,如: He is very tired,he has been working hard all day.,过 去,一般过去时 动词形态V-ed 用 法 例 句 过去的事情、The peoples Republic of China was founded in 1949. 动作、状态 John went to Shanghai yesterday. 过去的习惯 He used to take a walk in the morning. 过去发生的 The teacher stepped into the classroom. 连贯的动作 and asked the students to open the windows at once.,说 明,一般过去时常和下列表示过去时间的副词连用： ago an hour ago,a few days ago last last night/week/year yesterday yesterday morning,the day before yesterday this morning, just now, the other day,in +过去时间， in those days(=then),at that time. 表示“过去经常的习惯，而今不再”，则用 used to + V 现在完成时 ( have/has+p.p. ) 不可和表示过去的时间副词连用。 过去发生连串的动作，若用and, but, or, so等并列连词连接，通常全用一般过去时。,过去进行时 动词形态was/were+V-ing 用 法 例 句 I was watching TV at eight oclock 过去某事正 last night. 在进行的动作 It was raining at seven oclock this morning. 在过去某一动 He was sleeping when I arrived. 作发生时，另一 I was writing a letter when he 个动作正在进行 came in.,说 明,过去进行时常与下列句型表示： was 主语 + +V-ing when +主语+过去式V were 一般时所表示的动作通常比进形式的动作， 在时间上为短；所以表示“短”的动作用 V-ed ，表示“长”的动作用 was/were+V-ing I wrote a letter last night. 比较 I was writing a letter at 8 last night.,过去完成时 动词形态had+p.p. 用 法 例 句 过去某个 The train had gone before we reached 动作发生 the station. 以前的动作 After you had gone,I went to sleep. 在过去某 He said he had met me three years 时以前发 before. 生的动作 I had met him twice by yesterday.,说 明,过去的两个动作，当甲动作发生了之后，才发生乙动作，那么甲动作用had+p.p.,而移动作用V-ed。如例句中的火车“开走”在先，我们“到达”在后。 如句中有before,after等连词时，因为可以明显区分两件事情发生的先后，所以两者皆可用一般过去时表示，如： went After you , I went to sleep. had gone went you before I went to sleep. had gone 一般过去时与过去完成时之比较： I lost the watch that I had bought the other day. My uncle bought a coat in London and sent it to me 过去一连串的动作，如用and连接时，一般通常用“一般过去时”. hope, expect, intend等动词如果与“过去完成时”连用时，是表示“过去想做但没有现” I had hoped to go to Japan in July. = I hoped to have gone to Japan in July.,过去完成进行时 动词形态had been V-ing 用 法 例 句 We had been waiting for him an hour when 继 续 he arrived.
