现在进行时动词加ing的变化规律 1)一般情况下，直接加 -ing: 如：go—going answer—answering study—studying be—being see—seeing [注一] 和名词复数、一般现在时动词第三人称单数加-s(-es)不同， 动词末尾如为“辅音字母 + y”时，y不变，其后直接加ing。 如: study—studying fly—flying carry—carrying [注二] 动词结尾为辅音字母r时，加-ing，r在此必须发音。 如: water—watering answer—answering wear—wearing 2)以不发音的e结尾的动词，去掉e，再加ing 如：come—coming write—writing take—taking become—becoming 3)动词是闭音节的单音节词，或是以重读闭音节结尾的多音节词， 而末尾只有一个辅音字母时，这个辅音字母须双写，然后再加ing。 如：sit—sitting run—running stop—stopping begin—beginning admit—admitting forget—forgetting [注一] send，think，accept等动词虽是闭音节或以重读闭音节结尾， 但末尾有一个以上的辅音字母，因此，这个辅音字母不双写，应直接加ing。 如：sending thinking accepting 4)少数几个以-ie结尾的动词，须将ie变作y，再加ing。 如：die—dying tie—tying lie—lying躺，说谎 5)少数以-c结尾的动词变为现在分词时和过去式，须先将-c变为ck,然后再加-ing 或-ed 。 如：picnic—picnicking (picnicked) traffic—trafficking (trafficked)

2021届初三英语中考语法一轮复习讲义（三十） 行为动词的一般现在时用法总结与整理 行为动词的一般现在时 除了be动词（am，is，are）、助动词、情态动词以外的动词全部称为行为动词。在行为动词的句型中，主语为第三人称单数时的动词变化要特别注意（构成参见（第9章动词概说））。行为动词一般现在时的否定句和一般疑问句要加do/does，这和be动词是不同的。 1.行为动词一般现在时的肯定句 I play baseball every Sunday.（我每个星期日都打棒球。） She usually does her homework at school.（她通常在学校做作业。）（1）主语为第一、二人称或第三人称复数时 主语为第一人称I/we、第二人称you或第三人称复数时，谓语动词没有形式的变化。 句型：主语（除第三人称单数外）+行为动词（原形）+…… I go to school every day.（我每天去上学。） We have three children.（我们有三个孩子。） You sing very well.（你（们）唱得很棒。） They live far from school.（他们住得离学校远。） （2）主语为第三人称单数时 主语为第三人称单数时，谓语动词的一般现在时形式有变化，变化规律和名词的单数变复数形式相同。 句型：主语（第三人称单数）+行为动词（-s/-es）+…… He always wears (in) black.（他总是穿黑色的衣服。）
4.行为动词一般现在时的特殊疑问句 When do they have lunch?（他们什么时候吃午饭？） How many pairs of sneakers does she have?（她有多少双运动鞋？）（1）特殊疑问句的结构 句型：疑问词+一般疑问句？ Where do you live?（你住在哪儿？） How does he go to school?（他怎么上学？） When and where does Li Ming do his homework every day? （李明每天什么时候在哪里做作业？） How many emails do you send to your friends every day? （你每天给你朋友发多少封电子邮件？） 注意：特殊疑问句一般是将疑问词放在句首，后面用倒装句语序。但如果是对主语提问，则为：疑问词+谓语+其他成分？ Who（主语）looks after（谓语）the baby?（谁照看这个婴儿？）
一般现在时主语单三人称时的动词变化 ①在一般现在时中，当主语为第三人称单数时，动词要用“s”型（即第三人称单数形式）。 ②所谓动词“s”型的构成，与名词变复数相似，即： a）在动词尾直接加s。如： play—plays，want—wants，work—works，know—knows，help—helps，get—gets b）以字母s、ss、x、ch、sh或o结尾的动词加-es；如： guess—guesses，fix—fixes，teach—teaches，brush—brushes，go—goes，do—does，watch —watches，catch—catches c）以辅音字母＋y结尾的动词，先变y为i，再加-es。如： study—studies，carry—carries，fly—flies，worry—worries 第三人称单数练习 一．请选出正确的答案： 1. She (like / likes) to play football. 2. He (like / likes) drinking milk. 3. I (like / likes) to watch TV. 4. We (like / likes) to play badminton. 5. They (like / likes) to sing songs. 6.

延续性动词与非延续性动词及其转换 动词按其动作发生的方式、发生过程的长短可分为延续性动词与非延续性动词。 一.延续性动词表示能够延续的动作,如：learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等。延续性动词可以与表示时间段的状语连用。 表示时间段的短语有: ⑴for+一段时间, 如：for 2 years; ⑵since从句, 如since he came here; since+过去时间点名词, 如since last year, since 5 days ago。 例: He has lived here for 6 years. You can keep the book for 5 days. 二.非延续性动词也称终止性动词、瞬间动词, 表示不能延续的动作,这种动作发生后立即结束。如:open, die, close, begin, finish, come, go, move, borrow, lend, buy等。 非延续性动词在肯定句中与表示时间点的状语连用，如：two years ago; at 5 o'clock; 例:He died 5 years ago. 三.延续性动词与非延续性动词之间的转换：（考试重点） 例：He left five minutes ago. = He has been away for five minutes.
这句话的意思是指他离开的动作是5分钟之前发生的，是过去时。也就是说从他离开到现在已经有五分钟了，这个动作是延续的，要用现在完成时，并且要把原来的短暂性动词改为延续性动词。 一些短暂性动词及相应的延续性动词： arrive（get to /reach）→ be here (in) begin(start) → be on die → be dead come here（back）→be here（back） leave → be away (from) fall ill(sick, asleep)→be ill(sick, asleep) get up→ be up go/ get out（there）→ be out（there） finish → be over put on → wear 或be on open → be open（keep sth. open） join → be in或be a member of…+组织机构 close → be closed go to school → be a student borrow →keep buy/get →have catch(a cold) → have(a cold)
动名词的规则变化 1 一般情况下，直接在动词后加－ing eg: work ---- working study ----- studying 2 动词以不发音的－e结尾，要去－e加－ing take ----- taking make ----- making 3 重读闭音节的动词，要双写词尾字母，再加－ing cut ----- cutting Put—putting begin—beginning 4 以－ie结尾的动词，把变成y再加－ing lie ----- lying tie ----- tying die ----- dying 现在进行时基本用法 一、构成方法 现在进行时由 am/is/are 加现在分词构成。 二、用法说明 ■表示此时此刻或现阶段正在进行的动作。如： They’re having a meeting. 他们在开会。 I’m studying at an evening school. 我在上夜校。 ■表示计划或安排好了的将来动作，常与一个表示将来的时间状语连用。如：Mike is coming home on Thursday. 迈克星期四回来。 They’re having a party next week. 下星期他们将开一个晚会。 注：表示安排将要做的事，人作主语宜用现在进行时，事物作主语，宜用一般现在时。试比较： I’m not going out this evening. 今晚我不准备出去。(不宜说I don’t…) The concert starts at 7: 30. 音乐会七点半开始。 ■现在进行时与always, often, forever等连用表示赞扬、厌烦等语气。如：You’re always interrupting me! 你老打断我的话!(抱怨) My father is always losing his car keys. 我爸老丢车钥匙。(不满) She’s always helping people. 她老是帮助别人。(赞扬) ■现在进行时在时间和条件状语从句中，代替过去将来时。如： He promised to buy me a computer if he got a raise. 注意：像 be, think, understand, love, have, own, see, hear, find, belong to 等静态动词通常不用于进行时。 三．现在进行时的肯定肯定句、否定句、疑问句形式：
行为动词一般现在时的变化 珠村小学邓惠芳 这里所说的行为动词,指的是除be动词、情态动词和助动词之外的全部动词。行为动词为数众多,主语为第三人称单数he, she, it时,词形有变化。当主语是第三人称单数时，行为动词的一般现在时通常有三 种变化： 1、多数在动词后加s play—play s like—like s ,read-read s sing-sing s dance-dance s cook- cook s look- look s 2、以s，x，sh，ch，o结尾的动词加es go—go es wash--wash es, watch-watch es catch-catch es do- do es 3、以辅音字母加y结尾，把y改i再加es fly—fl ies study—stud ies try-tr ies (这种变化与名词的单数变复数有点相像) 那么，什么情况下用行为动词的一般现在时呢？当这个动作经常发生或表示习惯性的动作时，通常用一般现在时，它经常与表示频度的时间状语连用，如，当句子中有every day every year ,on Sunday, in the morning ,often, sometimes, usually, at one o’clock,等词时，用一般现在时。 He get s up at 6 o’clock. She usually watch es TV in the evening. Sometimes he go es to school by car. Tom often fl ies a kite on Sunday. 只有第三人称单数动词才要变，其他人称（I, you ,we ,they）则用动词的原形。
一般现在时动词变形 Company number：【WTUT-WT88Y-W8BBGB-BWYTT-19998】
一般现在时主要是表示经常或习惯性的动作，经常存在的情况或状态 1．be系动词变化； be（am, is, are）I am(我用am) You/they/we are （你他们我们用are） he/she/it is(他她它都用is) 2．实义动词变化：（主语通常是句子的第一个名词或代词） 句子主语是I / You /they /we 动词不变化，用原型 句子主语是第三人称单数，则要在动词原形后面加s, es 或将词尾的 y 变为 i 再加 es，写做：She goes to school. He studies English.(study → studies) 只有在第三人称单数用动词的“三单变化”，其他用动词的原形。1. 多数在动词后＋s play — plays ；like — likes （1）直接在动词词尾加-s. ask---asks work---works get---gets stay---stays （2）以字母s, x, ch, sh或o结尾的动词，在词尾直接加-es. watch---watches wish---wishes fix---fixes do---does go---goes pass---passes （3）以“辅音字母加 - y”结尾的动词，要先变y为i再加-es. try---tries study---studies cry---cries fly---flies 2. 不规则变化：be---- is are have----has
