　　河北中考单项选择对动词的考查主要涉及动词(包括实义动词和感官动词)、动词短语、情态动词、非谓语动词(只考查动词不定式)。完形填空中也涉及实义动词词义辨析，而词语运用中对动词的考查主要是和时态相结合。
预计2016年中考单选仍会从动词短语、情态动词、动词不定式方面来考查。完形填空主要考查动词词义辨析。

动词按照含义及它们在句中的作用分为4类，即行为动词，也称实义动词，(连)系动词、助动词和情态动词。情态动词将在第三节中具体讲解。河北中考侧重于感官动词的考查，偶尔也涉及实义动词的辨析。动词作为句子的核心成分，学生应重点掌握。
1．动词的分类
动词是表示动作或状态的词。动词分为四类：实义动词、连系动词、助动词和情态动词。
(1)实义动词的用法(及物动词与不及物动词)
实义动词是能独立作谓语的动词。按其是否跟宾语分为及物动词(vt.)和不及物动词(vi.)；按是否具有延续性分为延续性动词和短暂性动词。
及物动词
及物动词本身意义不完整，需要接宾语才能使其意思表达完整，如reach，ask，return，love，need。具体用法为：
①动词＋宾语。如：
He reached Canada yesterday.他昨天到达加拿大。
②动词＋宾语＋宾语补足语。如：
They asked me to go fishing with them.他们让我一起去钓鱼。
I saw the children play in the park yesterday.昨天我看见孩子们在公园里玩。
注意：带省略to的不定式或现在分词作宾补的常考动词有：make，let，have，see，watch，notice，hear等。
③动词＋间接宾语＋直接宾语。如：
I will return the storybook to him.我准备把故事书还给他。
注意：带双宾语的常考动词有：give，bring，buy，get，leave，lend，make，offer，pass，teach，tell，reach，return等。
不及物动词
不及物动词本身意思完整，无须接宾语，构成“主语＋谓语”的句型，如swim，come，go，run，travel等；如后面接宾语，必须与介词连用。如：
Lucy is swimming.露西正在游泳。
I am waiting for you at the school gate.我正在校门口等你。
有些动词既可作及物动词，又可作不及物动词。如：
We study English.我们学习英语。(及物)
We study hard.我们学习努力。(不及物)
The little girl is singing an English song.这个小女孩正在唱一首英语歌曲。(及物)
The little girl sings well.这个小女孩唱歌很好。(不及物)
(2)系动词的用法(共考查7次)
系动词本身没有词义，不能单独作谓语，必须和表语一起构成谓语，说明主语的状态、性质、特征或身份。
常考系动词的分类
类别 功能 例词
表示状态 表示主语所处的状态。 am，is，are，was，were
表示持续 表示主语继续或保持某种身份和状态。 keep，remain，stay，stand，lie
表示感官 表示人体感官的系动词。 look，feel，smell，taste，sound
表示状态变化 表示主语从一种状态变换到另一种状态。 become，get，go，grow，turn
　　常见用法的注意事项：
①一般情况下，系动词没有被动语态形式。
②表示状态的系动词一般不用于进行时(feel除外)；变化系动词表示“渐渐……”，可用于进行时。如：
It's getting warmer and warmer.天气渐渐变得暖和。
(3)助动词的用法(共考查5次)
助动词本身没有意义或意义不完全，不能单独用作谓语。助动词在句中与实义动词或系动词一起构成谓语，以表示时态、语态、人称和数。此外，还可以用来构成否定、疑问或强调的句型。具体用法见下表：
分类 作用
be am/is/are＋现在分词→现在进行时was/were＋现在分词→过去进行时be＋过去分词→被动语态
do 形式有do，does，did，用于构成疑问句和否定句，或用在动词前加强语气
have have/has＋过去分词→现在完成时had＋过去分词→过去完成时have＋been＋现在分词→现在完成进行时
will/shall will/shall＋动词原形→一般将来时would/should＋动词原形→过去将来时
【易错点提醒】will，would，shall，should除了表示单纯的将来时间以外，更多的是用作情态动词。
(4)情态动词的用法
(具体用法和习题详见本专题的第三节情态动词)
2．动词的基本形式
英语动词有五种基本形式，即：动词原形、第三人称单数(现在时)、过去式、过去分词和现在分词。
形式 构成 例词
动词原形 不带to的动词不定式形式。 be，do，have，come
第三人称单数
一般在动词原形后直接加 s。 work→worksread→reads
以s，o，x，z，sh，ch结尾的动词，后加 es。 go→goeswash→washes
以辅音字母加y结尾的动词，应将y改为i再加 es。 fly→fliesstudy→studies
过去式与过去分词
一般在动词原形后直接加 ed。 work→workedstay→stayed
在以 e结尾的动词后只加 d。 close→closedlike→liked
以辅音字母加y结尾的动词，应将y改为i再加 ed。 study→studiedcarry→carried
以重读闭音节结尾且末尾只有一个辅音字母的动词，双写此辅音字母再加 ed。 stop→stoppedplan→planned
现在分词
一般在动词原形后直接加 ing。 sleep→sleepingwait→waiting
以不发音的e结尾的动词，去e再加 ing。 smile→smilingmove→moving
以重读闭音节结尾且末尾只有一个辅音字母的动词，双写此辅音字母再加 ing。 sit→sittingdig→diggingplan→planning
少数以ie结尾的动词，变ie为y，再加 ing。 die→dyinglie→lying

动词短语在意义上相当于一个实义动词。动词短语辨析是近年来各省市中考常考点，同一个动词与不同介词或副词的搭配、不同动词与同一个介词或副词的搭配会产生不同意义的动词短语。动词短语的词义辨析试题旨在通过题干或微型语境考查考生对上下文的理解、动词短语的不同搭配识别、记忆及动词短语词义的辨析并恰当运用动词短语的能力。
分析河北近5年中考真题可看出单项选择对动词短语的考查主要集中在三方面：
(1)同一动词＋不同介词；(2)不同动词＋同一介词；(3)不同动词＋不同介词。
A．同一动词＋不同介词。如：
get短语：get up，get off，get to，get in
turn短语：turn on，turn off，turn up，turn down
B．不同动词＋同一介词。如：
cut down，look down，turn down，put down
put up，get up，look up，wake up
C．不同动词＋不同介词。如：
put on，take off，look for，cut down

第三节　情态动词
河北中考五年命题规律及趋势
考查点 年份 题号 考查角度 选项设置 分值
情态动词基本用法
2015 28 can't的用法 may/can't/must/needn't 1分
2014 34 can't表示不能 can't/mustn't/shouldn't/needn't 1分
2013 34 may表请求的用法 may/must/should/need 1分
2011 36 needn't基本用法 shouldn't/mustn't/needn't/can't 1分
情态动词表推测 2012 35 must表肯定推测 can/may/must/need 1分
　　情态动词为河北历年的必考点，主要为其基本用法和词义辨析，如：may在疑问句中表请求，needn't表示没必要，can't表否定推测和不能。特别是must的各种用法，如：must表肯定推测和强制命令。尤其注意在have to和must的问句中，肯定回答用must，否定回答用needn't或don't have to。同时，也涉及情态动词在被动语态中的运用。设题形式多为单句或对话形式，且词数为10～16。
预计2016年河北中考的单项选择题会出现一道考查情态动词基本用法的题，且偏向考查must的用法及其问句的答语。

need 表示需要、必须，主要用于否定句和疑问句中。 You needn't say sorry to him.你不需要对他说对不起。
情态动词的其他用法
一、must和have to
have to表示因外部因素而使得某人“不得不……”；must表示主观上感到“有必要……”。此外，must只有一般现在时，表示“过去”通常用had to，表示将来要用will have to。have/has/had to＋动词原形，在改否定句或疑问句时要外加助动词do/does/did。如：
She has to stay at home and look after her sick mother.她得待在家里照顾生病的妈妈。
Does she have to stay at home and look after her sick mother？她得待在家里照顾她生病的妈妈吗？
Must I go there with you？我必须和你去那儿吗？
二、can和be able to
两者表“能力”时用法相同，但can只有现在式can和过去式could两种形式，其他时态要用be able to来表示。另外，be able to常常有“做成了某事”的意味。如：
Jim can't speak Chinese.吉姆不会说中文。
We will be able to see him next week.下个星期，我们将会看到他。
三、can和may
1．can和may均可用来表示请求或许可，意为“可以”，一般可互换使用。如：
Can/May I help you？我能帮助你吗？
2．can与may表示可能性时的区别
(1)在肯定句中表推测时，may表示具体事情实际发生的可能性，can表示客观的(理论上的)可能性。
(2)在疑问句中表推测时用can(可能)，不用may。
(3)在否定句中表推测时用can't(不可能)，may not(可能不)。如：
She may be in the classroom.她可能在教室里。
Where can they be now？他们现在可能在哪儿？
四、maybe和may be
前者是副词，意为“大概，或许”，与perhaps/probably同义；后者属于情态动词，may与be动词用，意为“或许是”。如：
Maybe she is in the office.或许她在办公室。
She may be in the office.她或许是在办公室。
五、can't和mustn't
表否定推测时应用can't。mustn't意为“禁止，不允许”，不用来表推测，在肯定句中可用must表推测，意为“一定”。
六、情态动词的被动语态
含有情态动词的被动语态的结构为“情态动词＋be＋done(过去分词)”。做题时要兼顾情态动词和语态这两个方面的用法。如：
More and more trees must be planted in China.
在中国，越来越多的树必须被种植。
注意：(1)由need引出的一般疑问句，肯定回答常用must或have to；否定回答常用needn't。如：
—Need I answer the question？需要我回答这个问题吗？
—Yes，you must/have to./No，you needn't.是的，你必须回答。/不，你不需要。
(2)need作为实义动词有人称和数的变化，后面可接名词、代词、动名词及带to的动词不定式；可用于肯定句、疑问句和否定句中。如：
She doesn't need to see the doctor.She just needs a rest.她不需要看医生，她只需要休息一下。
