英语时态的问题

Question

例句+讲解+通俗。。。。等等

Answer 1

1. 以动作发生的时间状语为时态标志时间状语是特定时态的第一标志，如：now，at present往往是一般现在时或现在进行时的标志；yesterday，last week，a few years ago往往是一般过去时；at that time，at the time，at this time yesterday，then往往是过去进行时的标志；tomorrow，next week，in an hour往往是一般将来时的标志。如：—Surfing first started on the islands of Hawaii, didn’t it?—Yes, but now it _______ by people all over the world.A. is enjoyed B. is enjoyedC. has enjoyed D. will enjoy析：正确答案为A项。Now制约着该空，表示冲浪现在被全世界人民所喜爱，因此冲浪现在被全世界人民所喜爱，因此应用一般现在时的被动语态。It _______ Jack twenty minutes ________ the math problem yesterday.A. took; to work outB. takes; to work outC. has taken; working outD. is taking; working out析：正确答案为A项。yesterday表明第一空为过去性动词，故用一般过去时。—I can’t find my pen. Can I use yours?—Sorry, I _________ it now.A. am using B. was usingC. have used D. used析：正确答案为A项。now暗示此刻“我”正在使用钢笔，故应用现在进行时。 2. 以特定词汇为时态标志特定词汇也往往标志着特定时态，如：often，always，usually，never，seldom，once a week表示现在经常性、习惯性的动作，应用一般现在时；“for +时间段”和“since +时间点”往往表明到现在或过去某一时刻为止动作已持续若干时间，应用现在或过去完成时；by后接过去时间状语表示到过去某一时刻为止已经完成的动作，应用过去完成时；up to now / today, until now / today, recently, lately, in recent years, all these days, so far, several times往往表示到现在或今天为止动作已持续若干时间，或发生若干次数，应用现在完成时；in the past / last few years表示在到目前为止已经过去的几年里，应用现在完成时；in the next / following few years表示在随后的几年里，应用一般过去时；in the coming few years表示在即将到来的几年里，应用一般将来时。如：You don’t have to describe her. I _______ her several times.A. had met B. have met C. met D meet析：正确答案为B项。several times为完成时的标志，前句don’t形式表明后句标准对照时间点为现在，因此该空应用现在完成时。—Is your father a Party member?—Yes, he _______ the Party three years ago. He _________ a Party member for three years.A. has joined; has beenB. joined; has beenC. joined; wasD. was joined; is析：正确答案为B项。three years ago制约着第一空为过去性动作，应用一般过去时；for three years为完成时标志，因该句为直接引语，标准对照时间点应为现在，因此第二空应用现在完成时。—Do you know Betty very well?—Yes, she and I _______ friends since we met in Guangzhou last summer.A. have made B. have becomeC. have been D. have turned析：正确答案为C项。Since为完成时标志，该句为直接引语，标准对照时间点为现在，因此该空应用现在完成时。因since引导时间段，谓语动词应用持续性动词，故A、B、D项均错误。The supermarket is far from Mary’s house. So she ________ only once a week.A. goes shopping B. has been thereC. was shopping D. has gone there析：正确答案为A项。once a week暗示该空表经常性、习惯性的动作，应用一般现在时。 3. 以特定句型为时态标志有些特殊句型往往标志着特定时态，抓住这一点也可以巧解时态题。如：“It is the first (second…) time that”句型用现在完成时；“It is +时间+ since”句型用一般过去时，“It was +时间+ since”句型用过去完成时；时间状语从句和条件状语从句应用一般现在时代替一般将来时。如：—Will you come to the dinner party?—I won’t come unless Jenny _______.A. will be invited B. can be invitedC. invited D. is invited析：正确答案为D项。分析语境逻辑不难发现，该句为unless引导的条件状语从句，应用一般现在时代替一般将来时。Mr Green always tells his daughter a story before she ______ to sleep.A. will go B. wentC. is going D. goes析：正确答案为D项。分析语境逻辑可知，该句为before引导的时间状语从句，应用一般现在时代替一般将来时。 二、分析语境逻辑，巧解时态试题不少时态试题既无时间状语又无其他标志，语境抽象、语义空泛，考生们感到没有解题依据，找不到解题突破口。怎么办？标志不存语境在，分析语境学时态。如：—Hurry up! We’re all waiting for you.—I _____ for an important phone call. Go without me.A. wait B. was waitingC. am waiting D. waited析：正确答案为C项。分析语境逻辑可知，我不能和你去是因为此刻我在等一个重要电话，因此应用现在进行时。—Where is the librarian?—She ______ to the bookshop.A. went B. has gone C. goes D. will go析：正确答案为B项。分析问句逻辑可知，图书管理员此刻不在，那么她到哪里去了？to the bookshop暗示她已到书店去了，因此应用现在完成时。—I called you yesterday evening, but there was no answer.—Oh, I am sorry I _______ dinner at my friend’s home.A. have B. had C. was having D. have had析：正确答案为C项。分析语境逻辑可知，昨天你给我打电话时我正在吃饭，因此应用过去进行时。Don’t make so much noise. The students ________ an English class.A. are having B. have C. had D. were having析：正确答案为A项。由Don’t make so much noise的语境逻辑可以推断，学生们此刻正在上英语课，因此应用现在进行时。
