初二升初三之英语系列 主讲：陈燕萍老师动词变化规则在一般现在时中，当主语是第三人称单数时，谓语动词要用第三人称单数形式，即常在动词原形后加-s或-es。但有些同学们对于哪些主语是第三人称单数还不十分清楚，现归纳总结如下： 一、人称代词he, she, it是第三人称单数。如： 他喜欢看电视。 她十二点吃午餐。 它看起来像只猫。 二、单个人名、地名或称呼作主语；是第三人称单数。如： 韩梅看起来像她的母亲。 北京在中国。 王叔叔经常做蛋糕。 三、单数可数名词或this / that / the+单数可数名词作主语时，是第三人称单数。如： 马是有用的动物。 这本书是你的。 那辆小汽车是红色的。 这只猫是露茜的。 四、不定代词someone, somebody, nobody, everything, something等及指示代词this, that作主语时，是第三人称单数。如： 大家到齐了。 这块手表有毛病。 这是一支钢笔。 那是一块橡皮擦。 五、不可数名词作主语时为第三人称单数。如： 牛奶在玻璃杯里。 那面包很小。 六、当数字或字母作主语时，看作第三人称单数。如： 6 is a lucky number. 6是个吉利数字。 I is a letter. I是个字母。 动词第三人称单数词尾变化形式及读音动词第三人称单数词尾变化有三种形式。(1)一般动词在词尾加-s，-s在清辅音后读s，在浊辅音或元音后读zds读dz，ts读ts。如：helphelpshelps，knowknows，getgetsgets，readreadsphotophotos,(2)以字母s，x，ch，sh或有些以o结尾的动词加-es，-es读iz。如：guessguesses，fixfixesfiksiz，teachteaches，washwashes 注意：potatopotatoes, tomatotomatoes, gogoes，dodoes(3)以辅音字母+y结尾的动词，先变y为i，再加-es，-ies读iz。如：carrycarrieskAriz，flyfliesflaiz注：在playplayspleiz，saysayssez中，字母y前为元音字母，第三人称单数形式直接在动词后面加-s。(4)特殊词例外。如：beis，havehas以不发音字母“e”结尾的开音节词，如果尾音是s，z时，加“s”后字母“e”发音， 与所加“s” ，一起读做iz。 如： closecloses iz+es : watches TV brushes his teeth goes to bed goes to school does my homework does some reading规则动词和不规则动词的过去式变化如下： 一般情况下，动词词尾加 -ed ，如： 以不发音的 -e 结尾动词，动词词尾加 -d，如：以辅音字母 + y结尾的动词，把-y变为-i 再加-ed，如： 以一个辅音字母结尾的重读闭音节动词，双写词尾辅音字母，再加 -ed，如： 注：不规则动词的过去式变化规律性不强，须多加记忆。 go went make made get got buy bought come - came fly-flew 名词复数的规则变化 一般情况 加 -s 1.清辅音后，读/s/; 2.浊辅音和元音后，读 /z/; 以s,sh,ch, x等结尾的词 加 -es 读 /iz/ 以ce,se,ze, ge等结尾的词 加 -s 读 /iz/ 以辅音字母+y结尾的词，变y 为i 再加es， 读 /z/ 名词复数的不规则变化 1）注意：与 man 和 woman构成的合成词，其复数形式也是 -men 和-women。 如： an Englishman，two Englishmen. 但German不是合成词，故复数形式为Germans；Bowman是姓，其复数是the Bowmans。 2）单复同形 如： 但除人民币元、角、分外，美元、英镑、法郎等都有复数形式。如: 3）集体名词，以单数形式出现，但实为复数。 如： people ，police， cattle 等本身就是复数，不能说 a people，a police，a cattle，但可以说 a person，a policeman，a head of cattle，the English，the British，the French，the Chinese，the Japanese，the Swiss 等名词，表示国民总称时，作复数用。 如： 中国人民是勤劳勇敢的。 4）以s结尾，仍为单数的名词，如： a） maths，politics，physics等学科名词，为不可数名词，是单数。 b) news 是不可数名词。 c) the United States，the United Nations 应视为单数。 The United Nations was organized in 1945. 联合国是1945年组建起来的。 d) 以复数形式出现的书名，剧名，报纸，杂志名，也可视为单数。 The Arabian Nights is a very interesting story-book. 是一本非常有趣的故事书。 5) 表示由两部分构成的东西，如 若表达具体数目，要借助数量词 pair(对，双)； suit(套)； 6） 另外还有一些名词，其复数形式有时可表示特别意思，如： 动词过去式,过去分词不规则变化 AB型 can - could shall - should will - would may - mightAAA型 cost cost cost cut cut cut hit hit hithurt hurt hurt let let let must must must put put put set set set shut shut shutread read read AAB型 beat beat beaten ABA型 become became become run ran runcome came come ABB型 bring brought brought buy bought boughtthink thought thought catch caught caughtteach taught taught build built builtlend lent lent send sent sentspend spent spent dig dug dughang hung hung feel felt feltkeep kept kept sleep slept slept sweep swept swept leave left leftsmell smelt smelt spill spilt spiltlay laid laid pay paid paidsay said said sell sold soldtell told told sit sat satspit spat spat stand stood stoodunderstand understood understood learn learnt learnt mean meant meantspoil spoilt spoilt shine shone shonewin won won have had hadmake made made hear heard heardfind found found hold held heldABC型 begin began begun drink drank drunkring rang rung sing sang sungsink sank sunk swim swam swumblow blew blown fly flew flowngrow grew grown know knew knownthrow threw thrown draw drew drawn show showed shown break broke broken choose chose chosen forget forgot forgotten freeze froze frozen speak spoke spoken wake woke woken drive drove driven eat ate eaten fall fell fallen give gave given hide hid hidden ride rode ridden rise rose risen take took taken mistake mistook mistaken write wrote written am,is was been are were been do did done go went gone lie lay lain see saw seen wear wore worn 易错型 show showed shown draw drew drawn fall fell fallen feel felt felt hold held held help helped helped think thought thought thank thanked thanked take took taken talk talked talked get got got forget forgot forgotten meet met met mean meant meant hit hit hit hide hid hidden ring rang rung bring brought brought eat ate eaten beat beat beaten lie lay lain lay laid laid find found found found founded founded buy bought bought bring brought brought learn learnt learnt hear heard heard巩固练习题： 专练一I.写出下列动词的相应形式： 1. 第三人称单数： wash_ match _guess_ study_ finish_ go_ snow_ carry_ 2.写出下列动词的过去式：stop_ see_ drive _let_ carry_ keep_ join_ find_ think_ teach_ catch_ II. 用所给动词的适当形式填空： 1I _(write) to you as soon as I _(get) to London. 2.
