◇Part 01 语法知识清单
现在完成时的用法
用法一:表示过去发生的动作持续到现在,常与 “for + 时间段”“since + 时间点 / 过去时句子” 连用
【用法释义】
该用法强调动作从过去某一时刻开始,一直延续到当前时间,且动作可能仍在进行。例如:
I have lived in this city for 5 years.(我在这座城市住了 5 年了,现在仍住在这里)
She has studied English since she was 6 years old.(她从 6 岁就开始学英语,现在可能还在学)。
【主体结构】
结构为 “主语 + have/has + 动词过去分词 +(for/since + 时间状语)”,主语是第三人称单数时用 “has”,其余用 “have”。
1.for + 时间段:侧重于描述动作持续的总时长,回答 "How long...?" 的提问。
例:They have worked in this company for ten months.(他们在这家公司工作十个月了)
2.since + 时间点 / 过去时句子:强调动作的起始时间点,常搭配过去的具体时刻、节日或一般过去时从句。
例:We have known each other since 2018.(我们从 2018 年就认识了)
He has played the guitar since he joined the music club.(自从他加入音乐俱乐部,他就一直在弹吉他)
3.动词选用:必须使用延续性动词,若为短暂性动词需进行转换。例如 “buy(买)” 需转换为 “have(拥有)”,"join(加入)" 转换为 "be in(在... 里)" 等。
错误:She has bought the book for two weeks.
正确:She has had the book for two weeks.(这本书她买了两周了)
4.时间状语省略情况:当语境明确时,时间状语可省略,但动作延续性仍需通过上下文体现。
例:I have learned French.(暗示 “从过去学到现在”,未明确时长)

He ______ ______ math in this school since 2018.
答案与解析:
(一)单项选择
1.① 2. ③ 3. ①
【解析】
1.题干中有 “since they got married”(自从他们结婚以来),符合 “过去动作持续到现在” 的用法,需用现在完成时,主语 “my parents” 是复数,故用 “have lived”,选①。
2.句中 “for 3 years”(持续 3 年)是时间段,提示用现在完成时,主语 “Tom” 是第三人称单数,“practice” 的过去分词是 “practiced”,故用 “has practiced”,选③。
3.“since last Friday”(自从上周五以来)是现在完成时的标志,且句子是否定句,需用 “have not seen”,故第一空填 “have”,第二空填 “since”,选①。
(二)根据汉语提示完成句子答案
1.has grown
【解析】“for two years” 提示用现在完成时,主语 “my grandfather” 是第三人称单数,“grow” 的过去分词是 “grown”,故填 “has grown”。
2.has taught
【解析】“since 2018” 提示用现在完成时,主语 “He” 是第三人称单数,“teach” 的过去分词是 “taught”,故填 “has taught”。
用法二:表示过去发生的动作对现在造成的影响或结果,常与 “already”“yet”“just”“ever”“never” 连用
【用法释义】
现在完成时聚焦于过去发生的动作对现在产生的结果或影响,时间状语通常具有模糊性,这也是它与一般过去时的核心区别。例如:“I have already finished my homework.” 表明作业已完成,暗示说话者现在有空闲时间;“Have you ever been to Beijing?” 通过 “ever” 追问对方过往经历,实则关注对方当下是否具备相关认知。
already:常用于肯定句,位于助动词 “have/has” 与过去分词之间,强化动作完成状态,如 “She has already submitted the report.”;
yet:多用于否定句和疑问句句末,表示预期动作尚未发生,例如 “The package hasn't arrived yet.”;
just:强调动作刚刚结束,位置同 “already”,如 “He has just arrived home.”;
ever:用于疑问或否定句,询问是否有过特定经历,如 “Have you ever tried sushi?”;
never:用于否定句,语气强烈,强调从未有过某种经历,例如 “They have never visited Europe.”。

答案与解析:
(一)单项选择题答案
1.① 2. ② 3. ③
【解析】
1.句中 “yet” 是现在完成时的标志,常用于疑问句,结构为 “Have/Has + 主语 + 过去分词”,主语 “you” 用 “have”,“find” 的过去分词是 “found”,选①。
2.“just”(刚刚)提示动作刚完成,对现在有影响(可以问相关情况),用现在完成时,主语 “He” 是第三人称单数,“write” 的过去分词是 “written”,故用 “has written”,选②。
3.由 “so she is very excited to go there next week”(所以下周去那里她很兴奋)可知,琳达 “从未” 去过长城,“never” 表示 “从未”,符合语境,选③。
(二)根据汉语提示完成句子答案
1.have not decided

◇Part 02 核心考点讲练
考点 1:现在完成时与时间段连用
现在完成时表示过去发生的动作持续到现在或对现在造成影响,常与 “for + 时间段”“since + 过去时间点 / 过去从句” 等连用,此时谓语动词需用延续性动词,不能用短暂性动词。
【例题1】
— How long have you ______ this book?
— For two weeks.
A. borrowed B. kept C. lent D. bought
答案:B
解析:问句中 “how long” 表示时间段,需要与延续性动词连用。A 选项 “borrowed”(借进)、C 选项 “lent”(借出)、D 选项 “bought”(买)均为短暂性动词,无法持续一段时间;B 选项 “kept”(保留、持有)是延续性动词,符合 “for two weeks” 这一时间段的要求,故选 B。
【例题2】
My grandparents have lived in the small village ______ they got married.
A. when B. before C. since D. after
答案:C
解析:主句 “have lived” 是现在完成时,从句 “they got married” 是一般过去时,此处需要一个能连接现在完成时和过去时间点的连词。A 选项 “when”(当…… 时)常与一般过去时连用;B 选项 “before”(在…… 之前)和 D 选项 “after”(在…… 之后)均不符合现在完成时的时间逻辑;C 选项 “since”(自从…… 以来)可接过去时间点 / 过去从句,与现在完成时搭配,符合题意,故选 C。
【例题3】
Tom has ______ in Shanghai for five years. He likes the city very much.
A. worked B. arrived C. left D. joined
答案:A
解析:“for five years” 是时间段,要求谓语动词为延续性动词。B 选项 “arrived”(到达)、C 选项 “left”(离开)、D 选项 “joined”(加入)都是短暂性动词,不能与时间段连用;A 选项 “worked”(工作)是延续性动词,符合语法规则,故选 A。
考点 2:现在完成时与一般过去时的区别
现在完成时强调动作与现在的联系(如影响、持续到现在),不明确指出动作发生的具体时间;一般过去时仅表示过去发生的动作,常与具体的过去时间状语(如 yesterday, last week, in 2020 等)连用。
【例题1】
— ______ you ______ the film The Wandering Earth II?
— Yes. I ______ it last weekend.
A. Have; seen; saw B. Did; see; saw
C. Have; seen; have seen D. Did; see; have seen
答案:A
解析:第一句询问是否看过某部电影,强调动作对现在的影响(是否有 “看过” 的经历),用现在完成时,即 “Have you seen...”;第二句中 “last weekend” 是具体的过去时间状语,需用一般过去时 “saw”,故选 A。
【例题2】
My father ______ to Beijing twice. He ______ there last month.
A. went; went B. has gone; went
C. has been; went D. has been; has gone
答案:C
解析:第一句中 “twice”(两次)表示动作的次数,强调对现在的影响(有去北京两次的经历),且 “have been to” 表示 “去过某地(已回来)”,符合语境,故用 “has been”;第二句 “last month” 是具体过去时间,用一般过去时 “went”;“have gone to” 表示 “去了某地(未回来)”,不符合此处逻辑,故选 C。
【例题3】
— When ______ you ______ your homework?
— I ______ it an hour ago.
A. have; finished; finished B. did; finish; finished
C. have; finished; have finished D. did; finish; have finished
答案:B
解析:第一句询问 “什么时候完成作业”,侧重动作发生的具体时间,用一般过去时 “did you finish”;第二句 “an hour ago”(一小时前)是具体过去时间状语,需用一般过去时 “finished”;现在完成时不与具体过去时间状语连用,故排除 A、C、D,选 B。
考点 3:现在完成时的常用句型与标志词
现在完成时常见标志词有 “already”(已经,多用于肯定句)、“yet”(还、尚未,多用于否定句和疑问句)、“ever”(曾经)、“never”(从未)、“just”(刚刚)等;常用句型包括 “Have/Has + 主语 + 过去分词 +...?”“主语 + Have/Has+never/ever + 过去分词 +... ” 等。
【例题1】
— Have you ______ been to the Great Wall?
— No, I have ______ been there.
A. ever; never B. already; yet
C. yet; ever D. never; already
答案:A
解析:第一句是疑问句,询问 “是否曾经去过长城”,“ever”(曾经)用于疑问句中符合语境;第二句回答 “没有”,表示 “从未去过”,“never”(从未)符合否定含义。B 选项 “already”(肯定句)、“yet”(否定 / 疑问句)搭配错误;C 选项 “yet”(疑问句末)、“ever”(此处表否定不合适);D 选项 “never”(否定)、“already”(肯定)逻辑矛盾,故选 A。
【例题2】
We have ______ finished our English exam. We can have a rest now.
A. yet B. just C. never D. ever
答案:B
解析:句中 “finished our English exam”(完成英语考试)后提到 “可以休息了”,强调动作刚刚完成对现在的影响。A 选项 “yet” 用于否定句 / 疑问句;C 选项 “never”(从未)和 D 选项 “ever”(曾经)不符合 “已完成” 的语境;B 选项 “just”(刚刚)用于肯定句,符合现在完成时的用法,故选 B。
【例题3】
— Has Lucy come ______?
— No, she hasn't come ______. She may be on the way.
A. already; yet B. yet; already
C. yet; yet D. already; already
答案:C
解析:第一句是疑问句,第二句是否定句,“yet” 常用于疑问句和否定句末,表示 “还、尚未”;“already” 多用于肯定句,不用于疑问句和否定句末。A、B、D 选项中 “already” 的位置和用法均错误,故选 C。

参考答案
一、
1.D
【解析】句意:那个偏远的环礁几个世纪以来一直远离大陆。
考查动词时态和形式辨析。lie原形,意为“位于”;lies第三人称单数;lay过去式,意为“躺/放置”;lain过去分词。根据时间状语for centuries和句子结构,此处需用现在完成时态,且动词需用过去分词形式。故选D。
2.C

考查主谓一致和时态。当主语后接“as well as”引导的短语时,谓语动词的单复数形式应与第一个主语保持一致。“He”是第三人称单数,因此谓语动词需用单数形式。时间状语“for ten years”表示动作从过去持续到现在,需用现在完成时。故选C。
3.C
【解析】句意:中国现代科学家新博物馆自去年春天起就对公众开放了。

考查动词时态。根据“for a month”可知,句子应用现在完成时,且谓语动词应是延续性动词,die是短暂性动词,其延续性形式为be dead,所以句子应用has been dead。has died、had died和died都是短暂性动词的相应形式,不能与一段时间“for a month”连用。故选A。

6.C
【解析】句意:两会已经结束四年多了,但人们仍在讨论“双减”政策等话题。
考查时态和延续性动词。for more than four years表示一段时间,谓语动词需用延续性动词或表示延续状态的表达。start和end是短暂性动词,不能与一段时间连用,排除A、B、D;be over表示“结束”,是延续性状态,可与时间段连用。故选C。
7.D
【解析】句意:——迈克的家人去哪儿了?我这些天没见到他们。——除了祖父母外,他家的每个人都去无锡度假了,并且他们已经在那儿待了一周了。

8.D

10.A
【解析】句意:——自从你来到这里,你遵守学校规则多久了?——两年了。它们帮助我们保持安全。

11.B
【解析】句意:——你持有这个电子词典多久了?——三个月了。它对我的英语学习帮助很大。
考查时态和延续性动词。bought买;kept保有,持有。根据“For three months.”可知此处用现在完成时,结构为“have done”,且表示一个持续的时间段,因此要填一个延续性动词,keep是一个延续性动词。故选B。
12.A
【解析】句意:——自从你有了自行车,你遵守交通规则多久了?——半年了,我骑车一直很小心。
考查动词时态辨析。根据“since you got your bike”可知,这里需要用现在完成时表示从过去持续到现在的动作,have followed符合语境。故选A。
13.A
【解析】句意:——你使用这个学习应用多久了?——半年了。它对我的英语帮助很大。

14.C
【解析】句意:——你已经完成你的作业了吗?——还没有。我将在十分钟内完成。
考查现在完成时的用法。“yet”常用于完成时中表示“已经”,回答“Not yet.”表示尚未完成,强调动作对现在的影响,故问句需用现在完成时 (have/has + 过去分词);主语为“you”,助动词应用Have,动词finish的过去分词为finished。故选C。
15.A
【解析】句意:——你养成节约电的习惯有多久了?——三年了。我离开房间时总是关灯。

考查现在完成时。现在完成时表示从过去开始持续到现在的动作或状态。A项为现在完成时结构“have had”;B项为过去时;C项为一般现在时;D项为将来时。根据答句“For two years”可知,动作从过去持续到现在,应用现在完成时。故选A。
17.A
【解析】句意:——你使用这个共享单车应用多久了?——大约六个月了。它很有用。
考查现在完成时。根据答语“For about six months”可知,动作从过去持续到现在,此处应用现在完成时,其结构为have/has+动词过去分词,主语是you,助动词用have,use的过去分词是used。故选A。

23.D
【解析】句意:由于技术创新,齐齐哈尔的装备制造业近年来发展迅速。
考查动词时态辨析。develops发展,一般现在时;developed发展,一般过去时;is developing正在发展,现在进行时;has developed已经发展,现在完成时。根据“in recent years”可知,它表示从过去持续到现在的动作,句子时态用现在完成时。故选D。
24.A
【解析】句意:这位投身二十年护鹤事业的志愿者故事已在网上广泛传播,激励了成千上万的人们。
考查动词时态和语态。has spread现在完成时;spread一般过去时;was spread一般过去时的被动语态;is spreading现在进行时。根据“It has inspired…”可知,后句用现在完成时 (has inspired),说明“传播”动作发生在过去并对现在仍有影响,且主语“story”与“spread”是主动关系,故用现在完成时的主动语态 (has spread)。故选A。
25.D
【解析】句意:——齐齐哈尔在过去的五年里见证了巨大的变化。——是的。建造了更多的公园,环境好多了。
考查现在完成时和动词辨析。has taken已采取;has made已做出,make changes做出改变,主语多为人或组织;has had已有,have changes有变化,但表达生硬,不自然;has seen已见证,see changes见证变化,表示经历或观察到变化。根据“Qiqihar...great changes in the past five years.”可知,当主语是城市、时间、历史等无生命事物时,常用see表“见证”,此处强调齐齐哈尔在过去五年里亲历了诸多发展变化。故选D。
26.D
【解析】句意:我弟弟去过北京两次。他下个月还要再去那里。
考查动词时态辨析。根据“twice”表示过去经历,且后句“He will go there again next month”暗示他曾经去过北京(现在不在北京),需用现在完成时强调经历,应使用has been to表示“去过某地(现在已经回来)”。故选D。
27.A
【解析】句意:——你在这所学校学习多久了?——三年了。我是2022年来这儿的。
考查时态辨析。根据答语“For three years.”和“I came here in 2022.”可知,说话人从2022年至今一直在此学习,强调从过去持续到现在的动作或状态,应用现在完成时(have/has + 过去分词)。主语是you,助动词用have,study的过去分词是studied。故选A。
28.C
【解析】句意:——爸爸,我找不到我的手表了。你看到它了吗?——不,我没看到。我想你已经把它弄丢了!
考查动词时态。根据“Dad, I can’t find my watch. Did you see it?”可知,找不到手表,说明手表已经丢了,强调过去发生的动作对现在造成的影响,即现在找不到手表了,应该用现在完成时“have lost”。故选C。
29.A
【解析】句意:他从小就对太空旅行感兴趣。
考查介词辨析。since自从;for为了;in在……里面;on在……上面。根据“He has been interested in space travel”是现在完成时,结合选项可知,此处应用since引导时间状语从句,表示“自从他是个小孩的时候,他就对太空旅行感兴趣”。故选A。
30.D
【解析】句意:张先生现在不在办公室。他已经离开半小时了。
考查现在完成时和延续性动词的用法。left离开,一般过去时态,且是非延续性动词;has left已经离开,现在完成时态,不能与时间段连用;has gone已经走了,现在完成时态,不能与时间段连用;has been away已经离开,现在完成时态,延续性动词短语,表示持续状态。根据“for half an hour”可知,表示一段时间,需与现在完成时和延续性动词连用。故选D。
31.C
【解析】句意:自2020年以来,我一直住在生态城,而且我爱这个美丽的城市。
考查现在完成时。因为“since 2020”表示从过去开始持续到现在的动作,应用现在完成时“have/has+动词过去分词”,主语为I,助动词用have,故选C。
32.D
【解析】句意:这太不舒服了。我喉咙痛已经两天了。
考查现在完成时。“for two days”表示持续的时间段,需用现在完成时(have/has + 过去分词)强调动作或状态从过去开始并延续至今。故选D。
33.C
【解析】句意:她学习英语歌曲已经半年了。现在她能把很多英语歌曲唱得很好。
考查动词时态。根据时间状语“for half a year”(表示持续一段时间)和现在的结果“Now she can sing”,可知动作从过去开始并持续到现在,强调对现在的影响,应用现在完成时,其结构为has/have done。故选C。
34.C
【解析】句意:从去年开始,我们社区附近有了一个新公园。许多人去那里锻炼。
考查There be句型和现在完成时。根据“since last year”可知,此处描述过去发生的事情对现在造成的影响,应用现在完成时,其结构为“have/has done”;There be句型遵循“就近原则”,空后为“a new park”,助动词应用has。故选C。
35.A
【解析】句意:——你的爱好是什么?——我喜欢集邮。到目前为止我已经收集了数百张邮票。
考查非谓语动词和时态。like doing sth.“喜欢做某事”,是固定搭配,所以第一个空用collecting;时间状语“so far”为现在完成时标志,所以第二个空用have collected。故选A。
二、
36. found it hard
【解析】根据中英文对照,空格处缺“发现……很难”。find it + adj. + to do sth.“发现做……很难”是固定搭配,其中it作形式宾语,find要用过去分词found,与前面的“Have”,构成现在完成时结构;hard“困难的”,作宾语补足语。故填found;it;hard。
37. have done nothing
【解析】根据中英文对照可知,此处缺“什么也没做”。根据“so far到目前为止”这一标志词,可知句子需用现在完成时,结构为have/has + 过去分词,主语“you”对应的助动词是“have”;do的过去分词为done;什么都没翻译为nothing。故填have;done;nothing。
38. have done
【解析】根据句意可知,此处表示“已经做了”,用现在完成时“have done”,表示从过去某一时间开始一直延续到现在并还可能继续延续下去的动作或状态,“have”为助动词,“done”为过去分词形式。故填have;done。
39. stayed in touch with
【解析】根据题干和英文,此处缺少的信息为“与……保持联系”,stay in touch with“与……保持联系”,根据此处前面有have,符合现在完成时have/has done的结构,动词要用过去分词,stay的过去分词为stayed。故填stayed;in;touch;with。
40. How confident has been
【解析】根据中英文对照,此处缺少“多么自信”和“变得”。confident“自信的”,形容词,为感叹句的中心词,故应用how引导感叹句,对应感叹句的结构是“How + 形容词 + 主语 + 谓语!”how confident“多么自信”,句首单词首字母要大写;由since then可知,此处句子是现在完成时,主语是she,故此处表示状态用has been。故填How;confident;has;been。
41. brought great changes to
【解析】“给……带来变化”常用“bring changes to+宾语”;great“很大的”,修饰名词changes。根据“From that day on, the robot has...”可知,此句是现在完成时,动词用过去分词。故填brought;great;changes;to。
42. given help
【解析】根据中英文对照可知,此处缺少“已经帮助”。give sth. to sb.“给某人某物”,固定搭配。句子的时态为现在完成时,help“帮助”。故填given;help。
43. woken up
【解析】根据中英文对照可知,此处缺少“睡醒”,应填动词短语wake up;结合“has”和对应的汉语“已经睡醒”可知,时态为现在完成时,wake的过去分词是woken。故填woken;up。
44. has turned
【解析】turn ... into…“将……变成……”,根据中文语境可知,句子时态是现在完成时,主语是the Guo family,助动词用has,turn的过去分词为turned。故填has;turned。
45. is welcomed
【解析】根据中英文对照可知,此处缺少“欢迎”,应填动词welcome,主语The decision与谓语动词welcome之间是被动关系,所以需用被动语态“be+过去分词”,welcome的过去分词是welcomed;句子描述客观事实,时态为一般现在时,主语是The decision,所以be动词用is。故填is;welcomed。
46. are held
【解析】根据中英文对照可知,此处缺少“举办”,应填动词hold;根据“every year”可知,时态为一般现在时,主语“volunteer activities”与谓语动词之间是被动关系,所以此处是一般现在时的被动语态,结构为“be done”,主语是复数,be动词用are,hold的过去分词是held。故填are;held。
47. has brought big changes to
【解析】根据中英文对照可知,此处缺“给……带来了巨大的改变”,“带来了”用现在完成时,表示对现在的影响,主语This是单数,故用has brought;“巨大的改变”是big changes,因为change是可数名词,此处用复数表泛指;“给……”对应的介词是to,构成“bring changes to...”的结构。故填has;brought;big;changes;to。
48. have happened
【解析】对比中英文可知,空格中缺少“发生”,对应单词为happen,根据中文意思可知,本句应使用结构为“have/has+过去分词”的现在完成时,又因主语为复数形式“a large number of important changes”,助动词应为have。故填have;happened。
49. have been
【解析】对照中英文可知,缺少“曾经去过”。“曾经去过”表明时态是现在完成时,强调过去的经历对现在的影响。“曾经去过……”用动词短语have been to,表示曾经去过某地并已返回。故填have;been。
50. has been away from
【解析】根据中英文对照可知,此处缺“已经离开”,时态为现在完成时,结构为have/has done,be away from“远离”,主语Daniel为单数,助动词用has,be的过去分词为been。故填has;been;away;from。

2025-2026学年下学期八年级英语单元知识基础巩固(译林版2024)
Unit 1 Past and present语法讲练
目录
第一部分 语法知识清单锁定基础 高效学习
第二部分 核心考点讲练用法精析 变式巩固
第三部分 语法强化训练深度优化 扫清盲区
◇Part 01 语法知识清单
现在完成时的用法
用法一:表示过去发生的动作持续到现在,常与 “for + 时间段”“since + 时间点 / 过去时句子” 连用
【用法释义】
该用法强调动作从过去某一时刻开始,一直延续到当前时间,且动作可能仍在进行。例如:
I have lived in this city for 5 years.(我在这座城市住了 5 年了,现在仍住在这里)
She has studied English since she was 6 years old.(她从 6 岁就开始学英语,现在可能还在学)。
【主体结构】
结构为 “主语 + have/has + 动词过去分词 +(for/since + 时间状语)”,主语是第三人称单数时用 “has”,其余用 “have”。
1.for + 时间段:侧重于描述动作持续的总时长,回答 "How long...?" 的提问。
例:They have worked in this company for ten months.(他们在这家公司工作十个月了)
2.since + 时间点 / 过去时句子:强调动作的起始时间点,常搭配过去的具体时刻、节日或一般过去时从句。
例:We have known each other since 2018.(我们从 2018 年就认识了)
He has played the guitar since he joined the music club.(自从他加入音乐俱乐部,他就一直在弹吉他)
3.动词选用:必须使用延续性动词,若为短暂性动词需进行转换。例如 “buy(买)” 需转换为 “have(拥有)”,"join(加入)" 转换为 "be in(在... 里)" 等。
错误:She has bought the book for two weeks.
正确:She has had the book for two weeks.(这本书她买了两周了)
4.时间状语省略情况:当语境明确时,时间状语可省略,但动作延续性仍需通过上下文体现。
例:I have learned French.(暗示 “从过去学到现在”,未明确时长)

(一)单项选择
1.My parents ______ in this town since they got married.
① have lived ② lived ③ will live ④ live
2.Tom ______ playing the piano for 3 years.
① practices ② practiced ③ has practiced ④ will practice
3.We ______ not seen Mr. Li ______ last Friday.
① have; since ② had; for ③ did; since ④ do; for
(二)根据汉语提示完成句子

My grandfather ______ ______ these flowers for two years.
2.自从 2018 年以来,他就一直在这所学校教数学。(提示:teach math)
He ______ ______ math in this school since 2018.
用法二:表示过去发生的动作对现在造成的影响或结果,常与 “already”“yet”“just”“ever”“never” 连用
【用法释义】
现在完成时聚焦于过去发生的动作对现在产生的结果或影响,时间状语通常具有模糊性,这也是它与一般过去时的核心区别。例如:“I have already finished my homework.” 表明作业已完成,暗示说话者现在有空闲时间;“Have you ever been to Beijing?” 通过 “ever” 追问对方过往经历,实则关注对方当下是否具备相关认知。
already:常用于肯定句,位于助动词 “have/has” 与过去分词之间,强化动作完成状态,如 “She has already submitted the report.”;
yet:多用于否定句和疑问句句末,表示预期动作尚未发生,例如 “The package hasn't arrived yet.”;
just:强调动作刚刚结束,位置同 “already”,如 “He has just arrived home.”;
ever:用于疑问或否定句,询问是否有过特定经历,如 “Have you ever tried sushi?”;
never:用于否定句,语气强烈,强调从未有过某种经历,例如 “They have never visited Europe.”。

◇Part 02 核心考点讲练
考点 1:现在完成时与时间段连用
现在完成时表示过去发生的动作持续到现在或对现在造成影响,常与 “for + 时间段”“since + 过去时间点 / 过去从句” 等连用,此时谓语动词需用延续性动词,不能用短暂性动词。
【例题1】
— How long have you ______ this book?
— For two weeks.
A. borrowed B. kept C. lent D. bought
答案:B
解析:问句中 “how long” 表示时间段,需要与延续性动词连用。A 选项 “borrowed”(借进)、C 选项 “lent”(借出)、D 选项 “bought”(买)均为短暂性动词,无法持续一段时间;B 选项 “kept”(保留、持有)是延续性动词,符合 “for two weeks” 这一时间段的要求,故选 B。
【例题2】
My grandparents have lived in the small village ______ they got married.
A. when B. before C. since D. after
答案:C
解析:主句 “have lived” 是现在完成时,从句 “they got married” 是一般过去时,此处需要一个能连接现在完成时和过去时间点的连词。A 选项 “when”(当…… 时)常与一般过去时连用;B 选项 “before”(在…… 之前)和 D 选项 “after”(在…… 之后)均不符合现在完成时的时间逻辑;C 选项 “since”(自从…… 以来)可接过去时间点 / 过去从句,与现在完成时搭配,符合题意,故选 C。
【例题3】
Tom has ______ in Shanghai for five years. He likes the city very much.
A. worked B. arrived C. left D. joined
答案:A
解析:“for five years” 是时间段,要求谓语动词为延续性动词。B 选项 “arrived”(到达)、C 选项 “left”(离开)、D 选项 “joined”(加入)都是短暂性动词,不能与时间段连用;A 选项 “worked”(工作)是延续性动词,符合语法规则,故选 A。
考点 2:现在完成时与一般过去时的区别
现在完成时强调动作与现在的联系(如影响、持续到现在),不明确指出动作发生的具体时间;一般过去时仅表示过去发生的动作,常与具体的过去时间状语(如 yesterday, last week, in 2020 等)连用。
【例题1】
— ______ you ______ the film The Wandering Earth II?
— Yes. I ______ it last weekend.
A. Have; seen; saw B. Did; see; saw
C. Have; seen; have seen D. Did; see; have seen
答案:A
解析:第一句询问是否看过某部电影,强调动作对现在的影响(是否有 “看过” 的经历),用现在完成时,即 “Have you seen...”;第二句中 “last weekend” 是具体的过去时间状语,需用一般过去时 “saw”,故选 A。
【例题2】
My father ______ to Beijing twice. He ______ there last month.
A. went; went B. has gone; went
C. has been; went D. has been; has gone
答案:C
解析:第一句中 “twice”(两次)表示动作的次数,强调对现在的影响(有去北京两次的经历),且 “have been to” 表示 “去过某地(已回来)”,符合语境,故用 “has been”;第二句 “last month” 是具体过去时间,用一般过去时 “went”;“have gone to” 表示 “去了某地(未回来)”,不符合此处逻辑,故选 C。
【例题3】
— When ______ you ______ your homework?
— I ______ it an hour ago.
A. have; finished; finished B. did; finish; finished
C. have; finished; have finished D. did; finish; have finished
答案:B
解析:第一句询问 “什么时候完成作业”,侧重动作发生的具体时间,用一般过去时 “did you finish”;第二句 “an hour ago”(一小时前)是具体过去时间状语,需用一般过去时 “finished”;现在完成时不与具体过去时间状语连用,故排除 A、C、D,选 B。
考点 3:现在完成时的常用句型与标志词
现在完成时常见标志词有 “already”(已经,多用于肯定句)、“yet”(还、尚未,多用于否定句和疑问句)、“ever”(曾经)、“never”(从未)、“just”(刚刚)等;常用句型包括 “Have/Has + 主语 + 过去分词 +...?”“主语 + Have/Has+never/ever + 过去分词 +... ” 等。
【例题1】
— Have you ______ been to the Great Wall?
— No, I have ______ been there.
A. ever; never B. already; yet
C. yet; ever D. never; already
答案:A
解析:第一句是疑问句,询问 “是否曾经去过长城”,“ever”(曾经)用于疑问句中符合语境;第二句回答 “没有”,表示 “从未去过”,“never”(从未)符合否定含义。B 选项 “already”(肯定句)、“yet”(否定 / 疑问句)搭配错误;C 选项 “yet”(疑问句末)、“ever”(此处表否定不合适);D 选项 “never”(否定)、“already”(肯定)逻辑矛盾,故选 A。
【例题2】
We have ______ finished our English exam. We can have a rest now.
A. yet B. just C. never D. ever
答案:B
解析:句中 “finished our English exam”(完成英语考试)后提到 “可以休息了”,强调动作刚刚完成对现在的影响。A 选项 “yet” 用于否定句 / 疑问句;C 选项 “never”(从未)和 D 选项 “ever”(曾经)不符合 “已完成” 的语境;B 选项 “just”(刚刚)用于肯定句,符合现在完成时的用法,故选 B。
【例题3】
— Has Lucy come ______?
— No, she hasn't come ______. She may be on the way.
A. already; yet B. yet; already
C. yet; yet D. already; already
答案:C
解析:第一句是疑问句,第二句是否定句,“yet” 常用于疑问句和否定句末,表示 “还、尚未”;“already” 多用于肯定句,不用于疑问句和否定句末。A、B、D 选项中 “already” 的位置和用法均错误,故选 C。
