(1)表示过去发生的动作对现在产生的影响或结果,或说话时已完成的动作,常与so far、in the past/last few years、recently、lately、twice、for two years、how long、since ( ...ago)等连用。例如:

现在完成时除可以和for、since等引导的状语连用外,还可以和during/in/over the last (past)few years months、weeks ...)、in recent years、so far、up to/until/now等连用。但是现在完成时不能和明确的过去时间状语连用,如yesterday、last week、in 1998、two days ago等。下列句型中常用现在完成时:

“ago法”:He finished the work three hours ago.( √ )
“延续法”:He has been through (with) the work for three hours.( √ )
“since法”:It is/has been three hours since he finished the work.( √ )
②have/has been to和have/has gone to的区别:前者表示“去过某地,现在已经回来”;后者表示“去了某地,在去的路上或已经在那里(至今没有回来)”。
一般过去时和现在完成时的辨析
(1)两者都表示发生在过去的动作。但现在完成时表示过去动作与现在的关系,强调过去的动作对现在造成的结果或影响;一般过去时强调动作发生在过去某一时间,与现在不发生联系。
①They've gone to Paris.,他们到巴黎去了。(说明他们现在去巴黎了,不在这里)
②They went to Paris.,他们去过巴黎。(只说明去过,不表明是否现在仍在那里)
(2)现在完成时表示从过去发生到现在一段时间内的任何时间,可与so far、up to now、lately、ever since、in the past/last few years等表示现在的一段时间的状语连用,但不能和表示过去时间的状语连用;一般过去时表示的是过去某一特定时间或与现在无关的某一过去时间。
①I haven't seen the film yet.,我还没看过这部影片。(到目前为止)
②I saw the film the day before yesterday.,我前天看的这部电影。(表明看电影的时间是在前天)

他在狗进来之前关上了门。
②By then he had learned English for 3 years.

(2)表示动作或状态从过去某个时刻开始一直延续到另一个过去的时刻才完成,甚至还要继续下去。例如:
He had been ill for a week when we learned about it.
当我们得知此事时,他已经病了一个星期了。
(3)常用hope、expect、think、intend、want、suppose等动词的过去完成时来表示未实现的希望、打算或意图。例如:
We had expected that you would be able to win the match.
我们原以为你能赢得这场比赛。
(4)用于“hardly/scarcely/barely had ...done ...when ...”和“no sooner ...had ...done ...than ...”引导的复合句的主句中,常用倒装语序。when和than从句用一般过去时,表示“刚刚……就……”。例如:
Hardly had I got home when the rain poured down.
=No sooner had I got home than the rain poured down.
我刚到家,雨就瓢泼而下。
(5)It was/had been+一段时间+since从句,since从句中的谓语动词用过去完成时。例如:
It was ten years since we had had such a wonderful time.
我们十年没这么高兴了。
(6)This/That/It was the first/second ...time+that从句,that从句中的谓语动词用过去完成时。例如:
That was the first time (that) I had passed the exam.
那是我第一次考试及格。
3.现在完成进行时(have/has been+v.ing)
用来表示从过去某一时刻开始一直持续到现在(或今后还要继续下去)的动作。例如:
①He has been learning English for 6 years.
他已经学了六年英语了。(从过去某一时间开始学英语,强调到现在还在学)

二、被动语态
1.时态与动词形式
时态
动词形式
一般式
进行式
完成式
现在时
am/is/are+过去分词
am/is/are+being+过去分词
have/has+been+过去分词
过去时
was/were+过去分词
was/were+being+过去分词
had+been+过去分词

—
shall/will+have been+过去分词
过去
将来时
was/were going to/would be+过去分词
—
was/were going to/would+have been+过去分词
①含有情态动词的谓语的被动语态由“情态动词(can、may、must、have to等)+be+过去分词”构成。
②含有be going to、be to、used to、be about to等结构的复合谓语变为被动语态,其构成为“be going to(be to、used to、be about to)+be+过去分词”。
After school we went to the reading room to do some reading,only to be told that it was being decorated.
放学后,我们到阅览室去读书,结果却被告知它正在被装饰。(过去进行时的被动语态)
2.主动形式表示被动意义的几种情况
英语中有很多动词,如run、break、catch、clean、drive、look、open、sell、read、write、wash等,当它们被用作不及物动词来描述主语特征时,常用其主动形式表达被动意义,主语通常是物;在这种情况下,常常和easily、well等副词连用。
The machine runs well.
这种机器运转良好。
主动语态表示被动意义
①主动语态表示被动意义强调的是主语的特征,而被动语态则强调外界作用造成的影响。
②表示感受、感官的系动词feel、sound、taste、look等后跟形容词、名词构成系表结构,无被动形式。
③在need、want、require、deserve、bear等动词,worth等形容词的后面,动名词用主动形式表示被动意义,其含义相当于动词不定式的被动形式。
④在某些“主语(人/物)+be+形容词+不定式”结构中,不定式的主动形式表示被动意义。这些形容词有nice、easy、fit、hard、difficult、important、impossible、pleasant、interesting等。
The problem is difficult to work out.,这道题很难计算出。(可看作to work out省略了for me)
⑤be to rent/blame也属于主动形式表被动意义。
Who is to blame for the mistake?
谁应为这个错误受到谴责?
三、主谓一致
主谓一致是指谓语在人称和数上必须和主语的人称和数保持一致。
1.就近原则
就近原则即谓语动词的单复数形式取决于最靠近它的主语。
(1)在表示存在的there be句式中,主语是两个或多个并列名词(短语)时,be的形式与最近的一个名词(短语)保持一致。
There is a pen, two pencils and several books on the desk.
=There are two pencils, a pen and several books on the desk.
=There are several books, a pen and two pencils on the desk.
桌子上有一支钢笔、两支铅笔和几本书。
(2)由here、there等引导的倒装句中,若主语不止一个时,谓语动词与最近的主语保持一致(只用在一般现在时和一般过去时中)。例如:
①Here comes the bus.
公交车来了。
②Here is a pen and two books for you.
=Here are two books and a pen for you.
这是给你的一支钢笔和两本书。
(3)由连词or, either ...or ..., neither ...nor ..., not only ...but also ...、not ...but ...等连接并列主语时,谓语动词应与最近的主语保持一致。例如:
①Not only the students but also the teacher enjoys listening to the music.
=Not only the teacher but also the students enjoy listening to the music.
不仅学生,老师也喜欢听音乐。
②Neither you nor I am right.
=Neither I nor you are right.
你和我都错了。
③Am neither I nor you right?
你和我都错了吗?
2.语法一致
主语为单数形式,谓语动词也用单数形式;主语为复数形式,谓语动词也用复数形式。不可数名词作主语,谓语动词用单数;可数名词的复数形式作主语,谓语动词用复数。
I often help him and he often helps me.
我经常帮助他,他也经常帮助我。
(1)由with、along with、together with、as well as、besides、except、but、like、without、including、rather than等连接并列主语时,谓语动词必须与前面的主语在人称和数上保持一致。

这位老师和他的学生一起在花园种树。
②Email, as well as telephones, is playing an important part in daily communication.
电子邮件和电话在日常交流中扮演着重要的角色。
(2)如果主语是动词不定式、动词ing形式或主语从句时,谓语动词用单数。

眼见为实。
①Going to bed early and getting up early is a good habit.
早睡早起是一个好习惯。(把早睡早起当成一个动作)

他给我留了一些旧书。
(3)“one of+复数名词+定语从句”结构中的“复数名词”是先行词,定语从句的谓语动词用复数;如果one前有the、the only、the right等限定词修饰,则one是先行词,定语从句的谓语动词用单数。
①John is the only one of the students who has the keys.
约翰是唯一一个有钥匙的学生。
②John is one of the students who have the keys.
约翰是有钥匙的学生之一。
(4)“a number of+复数名词”作主语时,谓语动词用复数,意为“大量的”;“the number of+复数名词”作主语时,谓语动词用单数,意为“……的数量”。

我们每个人都有话要说。
(9)不定代词all、more、some、any、none等作主语时,谓语动词视指代情况而定,可用单数,也可用复数;但当它们指代不可数名词时看作单数,谓语动词用单数。

(11)某些名词如compasses(圆规)、trousers、shoes、glasses、pants(裤子)、jeans(牛仔裤)、shorts(短裤)、scissors(剪刀)等作主语时,谓语动词用复数,但当它们被a pair of修饰时,谓语动词用单数。

3.意义一致
主语形式虽为单数,但意义为复数,谓语动词用复数;主语形式为复数,而意义为单数,谓语动词用单数。
(1)主语是“the+形容词(或过去分词)”时,表示“一类人”,谓语通常用复数。这类词有the poor、the rich、the young、the old、the injured、the wounded等。

“四招定向”解决语法填空中的动词时态问题
1.通过看时间状语确定动词时态是最直接的方法。
2.当题干中没有时间状语,或时间状语不能完全决定所填动词的动作发生的具体时间时,动词的时态由其参照动词来决定。
3.当题干中无时间状语及参照动词,或时间状语和参照动词都不能确定所填词的动作的时态时,所填动词的时态由题干的具体意思或动作所发生的语境来决定。
4.英语中有一些句式的时态是固定的,如果题干中出现这类句式,考生应注意根据规则选用相应的时态。
(1)It is the first/second/ ...time that sb. have/has done ...
(2)It was the first/second/ ...time that sb. had done ...
(3)Sb. was/were doing sth. when ...did ...
(4)Hardly/Scarcely had sb. done sth. when ...did ...
(5)Sb. was/were about to do sth. when ...did ...
(6)It's (high) time that sb. did sth./should do sth.

[语篇解读]本文是一篇说明文。文章主要介绍了在吉尔吉斯斯坦,在科技、工程、数学、建筑等领域工作的女性人数较少。文章分析了产生这一情况的原因。
1.heavily [解析]考查副词。空处修饰动词短语depends on,故应用副词修饰。故填heavily。
2.as [解析]考查介词。句意:因此,吉尔吉斯人很少选择技术行业作为职业道路。由语境可知,空处表示“作为”,故填as。
3.graduates [解析]考查名词的数。graduate意为“大学毕业生”,为可数名词,此处表示复数意义,故应用其复数形式。故填graduates。
4.who [解析]考查定语从句的关系词。分析句子结构可知,空处引导非限制性定语从句,修饰先行词Alina Anisimova,指人,且在从句中作主语,应用关系代词who。故填who。
5.studying [解析]考查固定搭配。短语discourage sb.from doing sth.意为“打消某人做某事的念头”,是常用搭配。故填studying。
6.to marry [解析]考查固定搭配。短语expect sb.to do sth.表示“期待某人做某事”,此处为其被动形式,故填to marry。
7.surprising [解析]考查形容词。分析句子结构可知,空处作宾语补足语,应填形容词;结合语境可知,此处表示“令人吃惊的”,故填surprising。
8.has increased [解析]考查动词的时态和主谓一致。根据in recent years可知,空处应用现在完成时。the number of意为“……的数量”,作主语时后面的谓语动词用单数形式。故填has increased。

[语篇解读]本文是一篇说明文,文章介绍了“种子银行”。
1.why [解析]考查名词性从句。句意:许多人可能想知道为什么要储存种子。“1.__________ the seeds are stored”在句中作动词wonder的宾语从句,空处在从句中作状语。根据下文“One of the major reasons is to preserve the genes ...Another is to prevent ...to conserve biodiversity.”可知,此处应使用why引导名词性从句,表示“为什么,……的原因”。故填why。
2.loss [解析]考查名词。句意:另一个原因是防止稀有或濒危植物物种的遗传多样性丧失,努力保护生物多样性。设空处在句中作动词prevent的宾语,应填动词lose的名词loss。故填loss。

4.grown [解析]考查非谓语动词。句意:人类在几个世纪前种植的许多植物现在使用的频率较低;种子银行提供了一种保护历史和文化价值的方法。“4.__________(grow) centuries ago by humans”作后置定语修饰名词短语Many plants,Many plants与动词grow构成逻辑上的被动关系;结合空后的by humans可知,设空处应填grow的过去分词形式,表示被动。故填grown。
5.at [解析]考查介词。句意:在恒定低温和低含水量条件下保存的种子可以防止遗传资源的减少,否则,那些遗传资源只能通过田间采集保存。句中指“在恒定的低温低含水量条件下保存”,“在……温度/含水量”用介词at和temperature和water level进行搭配。故填at。
6.be damaged [解析]考查动词的时态和语态。句意:这些可供选择的“活”藏品可能会因自然灾害、疾病爆发或战争而受损。设空处在句中与can构成谓语,主语“These alternative ‘living’ collections”与动词damage之间为被动关系,由情态动词can可知,设空处应填be done构成被动语态。故填be damaged。
7.or [解析]考查连词。句意见上题解析。句中“natural disasters,outbreaks of disease”与war之间为并列关系,设空处应填连词连接三种可能的情况,连词or符合句意。故填or。
8.libraries [解析]考查名词的数。句意:种子“银行”包含了关于减少植物逆境的进化策略的宝贵信息,被认为是种子库,可以帮助创造现有种子的转基因版本。library为可数名词,根据句中的seed banks可知,此处应填library的复数形式。故填libraries。
9.existing [解析]考查形容词。句意见上题解析。设空处在句中作定语修饰名词seeds,形容词existing(现存的)符合句意。故填existing。
10.publicly [解析]考查副词。句意:大多数种子库是公共资助的,种子通常用于造福公众的研究。设空处修饰谓语动词are funded,应填public的副词publicly。故填publicly。
