7.英语四种时态的用法
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. 例:He worked in that hospital for 8 years.(他曾经在那家医院工作了8年.这只是讲述一个过去的事实,他现在已经不在那家医院了.) He has worked in that hospital for 8 years.(他已经在那家医院里工作了8年.表示他从过去开始工作,一直工作到现在,现在仍在那家医院工作.) B) 因为含有for加一段时间或since加一个时间点这样的时间状语的完成时,有动态和延续性的特点,所以不能使用终端动词或瞬间动词. 例:My sister has been married for 5 years.(过去分词做表语表示状态,可以延续) My sister has married. Don't disturb her.(终端动词) C) 在"this is the first/ second/ third…… time that……"句型里要求用完成时. 例:This is the second time that the products of our company have been shown in the International Exhibition.(这是我公司产品第二次参加国际展览会.) D) 句型"It is/ has been……since"所使用的两种时态都正确. 例:It is/ has been 10 years since I last saw him.(从我上次见到他以来已经10年了.) E) 在"no sooner than"、"hardly/ scarcely ……when"、"before"、"prior to"等句型中,主句要求完成时. 例:I haven't met that professor prior to today.(以前我从未见过那位教授.) 4. 现在完成进行时(have been doing) 用法:表示某一动作开始于过去某一时间,延续或重复地出现至今,或将继续延续至将来. 例:We have been working on this project for over a month now.(到目前为止,我们一直在处理那个项目,已经花了一个多月时间了.) 注意事项:与现在完成时相比,现在完成进行时更强调:在从过去到现在的时间里,动作或状态一直持续或一直反复出现. 例:1997年6月四级第45 题 It seems oil ___________ from this pipe for some time. We'll have to take the machine apart to put it right. A) had leaked B) is leaking C) leaked D) has been leaking 从本题上下文看,这两个句子的意思是:“看来,这个管道漏油已有一段时间了,我们将不得不拆卸机器排除故障.”第二句表示将要采取的措施.第一句动作发生在第二句之前,并且延续到现在为止仍在继续.因此,空格中需用现在完成时或现在完成进行时.D) has been leaking是现在完成进行时,因此是本题的答案.有11%的考生误选了B) is leaking.由于本句有时间状语for some time,表示谓语动作延续,谓语不能用现在进行时,必须用和完成时有关的时态.有些考生误选了C) leaked或A) had leaked。
