初中英语动词时态讲解及练习

16种英语时态总结归纳 时态（Tense）是表示行为、动作和状态在各种时间条件下的动词形式。因此，当我们说时态结构的时候，指的是相应时态下的动词形式。 英语时态分为16种：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。 例：He always helps others. （他总是帮助别人。） 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。 例：The next train leaves at 3 o'clock this afternoon.（下一趟火车今天下午3点开车。） How often does this shuttle bus run? （这班车多久一趟？） 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。 例：When you have finished the report, I will have waited for about 3 hours.（等你完成这份报告的时候，我就已经等了将近3个小时了。） 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。 例：I bought a new house, but I _________ my old one yet, so at the moment I have two houses. A) didn't sell B) sold C) haven't sold D) would sell 答案是C) haven't sold。 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。 例：Great as Newton was, many of his ideas ___________ today and are being modified by the work of scientists of our time. A) are to challenge C) have been challenged B) may be challenged D) are challenging 全句的意思是：“虽然牛顿是个伟大的人物，但他的许多见解直到今天还在受到挑战，并且被现代科学家的工作所修正。”challenge是及物动词，在本句中应当是被动语态；其动作延续到今天，所以要用现在完成时态。可见答案是C) have been challenged。A) are to challenge和D) are challenging都是主动语态，不可能是答案。B) may be challenged虽然是被动语态，但意思与全句内容不合，所以不对。 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。 例：John has broken his left leg.（约翰摔断了左腿。） 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。

动词被动语态讲解

模块八动词的被动语态 (1)被动语态定义：被动语态是动词的一种特殊形式,用来说明主语与谓语动词之间的关系。 如果主语是动作的执行者(即某人做某事),便叫主动语态； 如果主语是动作的承受者(即某事被做),便叫被动语态。 主动与被动的区别不是词序的区别,而是主语与谓语意义上的区别。 在英语中只有及物动词和一些相当于及物动词的词组才有被动语态的形式。 (2)英语中被动语态由“助动词be +动词的过去分词”构成。助动 词be有时态、人称和数的变化。被动语态后的by短语有时可 (1) 被动语态的用法： ①不知道谁是动作的执行者(即不知道谁做)时用被动语态,省 略by短语。 如：A man was killed in the accident.(一个人死于事故) This window was broken yesterday.(这扇窗子是昨天被打破的) ②不说或者众所周知是谁做时,用被动语态,省略by短语。 如：Rice is also grown in this place.(这个地方也种水稻) A railroad will be built here in three years.(三年之后这里

将要修建一条铁路) ③强调动作的承受者,句尾加by短语。 如：It was written by Lu Xun.(它(书)是鲁迅写的) A pet dog is never killed by its owner.(宠物狗是不会被主 人宰杀的) (2) 主动语态如何改写为被动语态： + 受者) + (动作的承受者) (be +过去分词) (动作的执行者) (3) 注意点： ①“动词+间接宾语+直接宾语”改为被动时,可以用间接宾语做被动句的主语。如： His teacher gave him a dictionary. →He was given a dictionary by his teacher.(老师给他一本字典 →他得到老师一本字典) 也可以用直接宾语做被动句的主语,但是需用to或者for引出 原句的间接宾语。 如：His teacher gave him a dictionary. →A dictionary was given to．． him by his teacher.(老师给他一本 字典→一本字典由老师送给了他) /His father made him a kite. →A kite was made for ．．．him by his father.(他的父亲给他做了一个风筝→一个风筝由他的父亲做给了他) ②“动词+宾语+动词原形”改为被动时,动词原形前要加to. 如：The boss made the poor man work 12 hours a day. →The poor man was made to．． work 12 hours a day.(老板让这个可怜的人一天工作12小时→这个可怜人被迫一天工作12小时)

易错题汇编：动词时态与语态 一．The twins, Who their homework, were allowed to play badminton on the playground. A. will finish B. finish C. have finished D. had finished 【考点】考察时态 【答案】D 【解析】句义：已经完成了他们的家庭作业，这对双胞胎被允许在操场上打羽毛球。根据句义可知他们完成作业是在被允许到操场上打羽毛球之前。而他们被允许打羽毛球已经使用了一般过去时，所以完成作业应该使用过去完成时。故D 正确。 【举一反三】--- Peter, do you know who____ my dictionary ? ---Sorry , I don’t know . I didn’t do it . A. has taken away B. was taking away C. had taken away D. is taking away 【答案】A 试题分析：句意：--皮特，你知道谁把我的字典拿走了吗？--对不起，我不知道，我没有拿。这里拿走发生在过去，强调对现在造成的影响，不知在什么地方，故用现在完成时。 二. ---Hi, let’s go skating. --- Sorry, I’m busy right now. I _______ in an application form for a new job. A. fill B. have filled C. am filling D. will fill 【考点】考察时态 【答案】C 【解析】句意：—喂，我们五滑冰吧！—对不起，我现在很忙，我正在填写一份新的工作申请表。根据句意可知本句是在叙述说话时正在进行，正在发生的事情，所以使用现在进行时。故C正确。
