汉语的时态大多是通过副词来表达的,而高中英语的时态是靠动词的变化和时间状语来表达的。高中英语中的时态共有十六种,但是常考的或较常用的只有9种,而且重点测试完成时态。要掌握英语的时态和语态,必须掌握好高中英语中的助动词(do, be, have)和时间状语这两个核心问题。 一般现在时 主要用来表示人、事物的现在状况和特点;表示经常或习惯性的动作,句子中常有often, always, from time to time 等时间状语; 表示客观规律和永恒真理等。例句: He usually goes to work at 7 o’clock every morning. She has a brother who lives in New York. The earth goes around the sun. Guangzhou is situated in the south of China. 考点一:表示永恒的真理,即使出现在过去的语境中,仍用一般现在时。I learned that the earth goes around the sun when I was in primaryschool. 考点二:在时间和条件状语从句中,代替一般将来时;常用的引导词有:时间:when, until, after, before, as soon as, once, the moment/the minute, the day; 条件:if, unless, provided. If he accepts the job, he will get more money soon. 考点三:在make sure (certain), see to it, mind, care, matter+宾语从句中,从句用一般现在时代替一般将来时。 So long as he works hard, I don’t mind when he finishes the experiment. 只要他努力工作,我不介意他什么时候做完试验。 考点四:在the more… the more… (越……越……) 的句型中, 若主句是一般将来时, 从句通常用一般现在时。 The harder you study, the better results you will get. 现在进行时 表说话时或目前一段时间内正在进行的活动:表感情色彩,加强语气。与频率副词,如always,constantly,continually,again等连用表示说话人的某种感情色彩(赞叹、厌烦、埋怨等)。例句: We are having English class. The house is being built these days. The little boy is always making trouble. 考点一:在时间状语或条件状语从句中表示将来正在进行的动作。 Look out when you are crossing the street. Don't wake him up if he is still sleeping at 7 tomorrow morning. 考点二: 表示在最近按计划或安排要进行的动作(这时多有表示将来的时间状语)。 Marry is leaving on Friday. 现在完成时 表示动作发生在过去,完成在过去,但强调与现在情况仍有联系,其结果或影响仍存在。现在完成时有一些标志性的时间状语考点一:for + 时间段;since + 时间点 They have lived in Beijing for five years. They have lived in Beijing since 1995. I have learned English for ten years. 考点二:常见的不确定的时间状语:lately; recently, just, already, yet,up to now; till now; so far, these days, Has it stopped raining yet ? 考点三:在表示“最近几世纪/ 年/ 月以来……”时间状语中,谓语动词用现在完成时。 in the past few years/months/weeks/days;over the past few years; during the last three months; for the last few centuries, through centuries; throughout history 等 考点四:表示“第几次做某事,”或在 “It is the best (worst, most interesting ) +名词+that” 后面跟现在完成时。 This is my first time that I have visited China. This is the most interesting film I have ever seen. That is the only book that he has written. 一般过去时 表在过去某个特定时间发生且完成的动作,或过去习惯性动作,不强调对现在的影响,只说明过去。常跟明确的过去时间连用,如:yesterday; last week; in 1945, at that time; once; during the war;before; a few days ago; when考点一:used to + do,表示过去经常但现在已不再维持的习惯动作。to为不定式,后接动词原形。 be/become/get used to + doing,表示习惯于。 He used to smoke a lot. He has got used to getting up early. 考点二:在时间和条件状语从句中,代替过去将来时。 He promised to buy me a computer if he got a raise. 过去进行时 表示过去某个时间点或某段时间内正在发生的动作。例句:The boy was doing his homework when his father came back fromwork. He was taking a walk leisurely by the lake when he heard someoneshouted for help. What were you doing at nine last night? The radio was being repaired when you called me. 过去完成时 表示过去某个时间之前已经完成的动作,即过去完成时的动作发生在“过去的过去”,句中有明显的参照动作或时间状语,这种时态从来不孤立使用 ( before, after, by, up till )例句: There had been 25 parks in our city up till 2000. By the end of last term we had finished the book. They finished earlier than we had expected. 考点一:用于hardly/scarcely...when; no sooner ...than 句型中,主句用过去完成时,从句用一般过去时。 I had hardly finished my work when he came to see me. I had no sooner got into the room than it began to snow. No sooner had I arrived home than the telephone rang. (注意主谓倒装) 考点二:表示“第几次做某事”,主句用过去时,从句用过去完成时。 That was the second time that she had seen her grandfather. It was three years since we had parted. 考点三:动词hope, expect, think, intend, mean, want, suppose, plan用过去完成时,表示未实现的愿望、打算和意图。 I had hoped that I could do the job. I had intended to see you but I was too busy. 一般将来时 表在将来某个时间会发生的动作或情况。常和tomorrow, next year, in 2008等表示将来的时间状语连用,其表现形式多达5种。例句:Beijing will host the 29th Olympic Games in 2008. 考点一:一般将来时总是用在一些时间状语从句或条件状语从句的主句中We will begin our class as soon as the teacher comes. (主句用一般将来时,从句中一定要用一般现在时替代一般将来时。) 考点二:某些表示短暂性动作的动词如arrive, come, go, leave, start等,用现在进行时形式表示将来。 I am leaving for Beijing tomorrow. 考点三:“祈使句 + and/or + 句子”,这种结构中and后面的句子谓语用一般将来时。Use your head and you will find a way. 考点四:“am (is, are) going to + 动词原形”表示打算要做的事或可能要发生的事。 “am (is, are) about to +动词原形”表示按照预定计划或打算准备着手进行的动作。 “am (is, are) to + 动词原形”表示必须、必然或计划将要做的事。 They are to be married in this May. 将来进行时 表将来某个时间正在发生的动作,或按计划一定会发生的事情。例句: I’ll be doing my homework this time tomorrow.
