内容正文:

现在完成时:have / has + 过去分词 (done) 考点一:两大基本用法(必须先分清) 已完成(结果影响) 1.1 含义:过去发生的动作,现在已经完成,强调对现在造成的影响或结果。 1.2 标志词:already, yet, just, ever, never 1.3 例句:I have lost my keys.(结果:我现在进不去门) 未完成(持续) 2.1 含义:过去发生的动作或状态,一直持续到现在,并且还可能继续下去。 2.2 标志词:for + 时间段,since + 时间点/从句 2.3 例句:He has lived here for 10 years.(10年前住到现在,还可能继续住) 考点二:高频时间状语(看到即选) 出现以下标志词,首选现在完成时(考场秒杀技): 肯定句:already(已经),just(刚刚),ever(曾经),never(从不),yet(用于否定句/疑问句:还/已经) 持续:for + 一段时间(如 for 3 years),since + 过去时间点/从句(如 since 2018, since I was born) 笼统时间:so far / up to now(到目前为止),recently / lately(最近),in the past few years(在过去的几年里),over the years 注意:如果句中有具体的过去时间(yesterday, last week, in 2020, 3 days ago),绝对不能用现在完成时,必须用一般过去时。 考点三:与一般过去时的终极区别(必考陷阱) 这是考试中最容易丢分的地方,记住这个黄金分割点: 时态 着眼点 是否强调现在? 时间状语 现在完成时 强调现在的结果或影响,不关心具体发生时间。 强调现在 不接具体过去时间 一般过去时 仅陈述过去发生的事实,与现在无关或联系断裂。 只看过去 接 yesterday, last..., ...ago, in 1990 等 经典对比(必看): I have lost my phone.(手机现在不见了,强调目前状态) I lost my phone last week.(只是陈述上周丢了,现在找没找到不管,也许找到了) She has been to Beijing.(她去过北京,人现在回来了,强调"有去过"的经历) She went to Beijing last month.(她上个月去北京了,人可能还没回来,只是陈述动作) 考点四:非延续性动词(瞬间动词)的转换(超级高频) 核心规则:像 buy, borrow, die, join, leave, arrive, marry 这类瞬间就完成的动词,不能与"for + 时间段"或"since"连用(因为它们无法持续)。 考场必杀技:遇到这种搭配,必须把瞬间动词换成对应的延续性状态动词。 瞬间动词(短暂) 延续性动词/状态(可持续) buy(买) have / has had(拥有) borrow(借入) keep(保存) die(死) be dead(死的状态) join(加入) be in / be a member of(是成员) leave(离开) be away(离开的状态) arrive / come(到达) be here / be in(在这儿) begin / start(开始) be on(在进行中) marry(结婚) be married(已婚) 真题陷阱: He has bought the car for 5 years.(错误,buy 不能持续) He has had the car for 5 years.(正确,have 表示拥有) 考点五:have been to / have gone to 的区别(1分必拿) 短语 含义 是否在说话地? have/has been to + 地点 去过某地(已经回来了) 在 have/has gone to + 地点 去了某地(在路上或已到达,还没回来) 不在 例句: Where is Tom?(汤姆在哪儿?) He has gone to the library.(他去图书馆了,不在这儿) I have been to the library twice this week.(我这周去过两次图书馆了,人现在在这儿) 考点六:固定句型(见到直接套) 这两个句型是送分题,看到秒选现在完成时: This/It is the + 序数词 + time that...(这是第几次做某事) 1.1 主句是 is,从句必须用现在完成时。 1.2 例:This is the third time that I have visited Chongqing. This is the + 最高级 + 名词 + that...(这是最……的……) 2.1 从句用现在完成时。 2.2 例:This is the best movie that I have ever seen. 考场终极避坑口诀 看标志:有 for/since/so far,先选现在完成时。 看时间:有具体过去时间(yesterday/last...),坚决用一般过去时。 看持续:for + 时间段搭配 buy/borrow/die,立刻换词(换成 have/keep/be dead)。 看去了没:人在哪?在说话地就用 been to,不在就用 gone to。 现在完成时专项练习题 一:动词填空(10题) She ________ (live) in this city since she was born.
