7、,thirteen, fifteen 看仔细。十八需要看准确,eighteen 只有一个。二十到九十加ty,twenty, eighty 重点记。forty 去掉字母u,thirty, fifty 更出奇。十位数后接个位数,表示数字几十几。排列顺序不费力,连字符号莫丢弃。写到几百几十几,and 把百与十系。巧学妙记加努力,hundred 是你的好成绩。基数词变序数词歌诀基变序很容易,结尾加上 “th”,一二三特殊记,结尾各是t、d、d。八减t, 九去e, f来把ve替,y改为 “ie”,结尾仍有 “th”。若是遇到几十几,只变个位就可以。 one- first; two- second; th

9、。若是嫌此还麻烦,先 “点”后 “分”也能办。ten to twelve / twelve tentwenty past nine / nine twentya quarter to seven / seven fifteen half past five / five thirty倍数表达法倍数表达有三样,”A + 倍数 + ( ) B”是同项。同项括号有三种, “比较极 + than“是首桩;“as + 原级 + as” 不可忘,填完 “the + 名词 + of”才够量。1) The playground is three times bigger than that one.2) Th
10、e playground is three times as big as that one.3) The playground is three times the size of that one.人称代词、物主代词变化口诀(一)人称代词有变化,主格、宾格记牢它;I, me; we, us; you 和 it 无变化;she 和 her; he, him; they 的宾格是 them。(二)物主代词分两家,形、名词性各一霸;his, its 无变化, my, mine 记牢它;其余变形规律化,形容词(性)后加尾巴(-s)。巧学不定代词不定代词美名扬,修饰成分后边藏;单数动词作谓语,何时何
11、地都一样。1) I have nothing important to say.2) Nobody in our office has been invited to his birthday party.动词种类速记歌诀英语动词分四种,行为、连系、助动、情。动作状态为行动,充当谓语有作用。连系动词有词义,不能独立作谓语。须与表语在一起,常用look, become & be。助动词来无词义,不能独立做谓语。时态、疑问和否定,do, be, will 最尽力。情态动词must, can, may, 表示情态和语气。人称与数无变化,动词原形跟着它。巧学 have 的三种使役用法have 用作使役
12、动,后跟宾补有三种。若 “叫别人做某事”,have sth. done 记心中,done 为过分表被动,get, have两相同;“听任” “保持”用doing,现分进行有主动。如 “让某人做某事”,have sb. do sth. 可使用。不定式 do 把 to 省,let, make, have 孪弟兄。1) I have / get my hair cut once a month.2) You had the light burning all night yesterday.3) Dont let /make /have the child stand outside.一般现在时用法
13、歌诀用好一般现在时,时间状语需牢记。一般现在时,表示经常发生事。主语人称是三单,动词要把-s /-es 添。主语之后是谓语,肯定陈述的语序。一般疑问 do 当先,否定谓语前 dont 添。基本用法要记清,状语习惯经常性。客观真理和能力,有时还表将来时。动词有三单,词尾常把 -s 添,词尾若是 s, ch, sh,直接加上 es。词尾有字母 x 或 o,加上 es 不用愁。辅音字母加 y,要把 y 先变成 i。动词加-s 或 es 方法歌work- works; wash- washes; watch- watches; pass- passes;study- studies; do does;
14、 go goes 现在进行时用法口诀主语在句首,am, is, are 跟在后。现在分词跟着走,其他成分不能丢。表示动作正进行,句中 now 时间定。一般问句这样变,把 be 提到主语前。否定句式也简单,be 后再把 not 添。e.g. The old man is walking along the river.现在进行要注意,有be还有ing;be 的形式看主语,双写情况更留意;否定be后加not, 疑问主语前是be。现在分词构成口诀现在分词用途多,进行时态不可缺。它的构成很好记,动词后缀 -ing。词尾若有哑音 e,去 e 再加没问题。一辅重读闭音节,这个字母要双写。还有一点要注意,改
15、 ie 为 y 再加 -ing。 teach- teaching; like- liking; lie- lying; die- dying get getting; begin -beginning一般过去时用法歌诀动词一般过去时,表示过去发生事。句中谓语用过去式,过去时间作标记。否定句,很简单,主语之后 didnt 添。疑问构成也不难,主语前面 did 加。还有一点不能删,后面的动词要还原。e.g. 1) Last week, I listened to his music, but I didnt like it at all. 2) Did you go to the cinema l
16、ast Sunday?规则动词过去式构成方法口诀过去式构成有规律,一般词尾加 -ed。如果词尾有个 e,只要直接加上 -d。“辅音字母+ y”在词尾,变 y 为 i 加 -ed,“一辅重闭”做尾巴,双写之后 ed 加。travel 一词是特例,双写 l 再把 -ed加。过去式用于过去时,表示过去发生的事。以后学习过去分词,变化规律同过去式。push- pushed; like- liked; study- studied; stop- stopped; travel- travelled一般将来时用法歌诀动词一般将来时,表示将要发生事。谓语动词要记清,助词 will + 原形。时间状语表将来,
17、一般情况离不开。要变一般疑问句,will 主语前面移。否定句式也简单,will 后边 not 添。1) They will have a meeting tomorrow.2) -Will you go home next weekend? -No, I will not / wont.巧记be going to用法歌诀be going to 表打算,准备计划将来干。表可能,有必然,通过现象来判断。使用它,要注意,疑问形式 be 前提。否定句,更简单,not 放在 be 后边。to 之后动原形,be 的形式看人称。下列词,要注意,come, go 和离身去(leave)。进行时,表将来,牢牢记
18、住莫忘记。现在完成时用法歌诀学习现在完成时,谓语结构要记清。-“have / has + 过去分词”。主要用法有两个-过去发生的动作,对现在影响或结果,just, already 常用着。过去动作或状态,一直延续到现在,for 或 since 把时间带。1) The Smiths have already been to many countries.2) He has studied English for over twenty years / since he was ten years old.have been to 和 have gone to 区别歌诀been to, gone
19、to 意不同,两者用法要分清:“have been to + 地名”, “曾经到过某地”人已回;“have gone to + 地名”,“去了某地”人未归。1) My father has been to Beijing several times.2) -Where has Tom gone?-He has gone to France.had 加上 “过去分”,构成过去完成时。过去完成的意义,也表 “完成”或 “延续”。不过 “时间”往前推,它表 “过去的过去”。若有主、从两个句,先后动作分别叙。哪个在先哪 “完成”,哪个在后哪 “过去”。过去完成时用法口诀1) We had learnt
20、 30 passages by the end of last month.2) When he came, I had finished my homework.巧记十个瞬间动词开始离去,借来还,出生入死,买到家。begin leave go borrow come returnjoin die buy arrive被动语态口诀(一)动作谁做的不知道,说出谁做的没必要。 接受动作者要强调,用被动语态最为妙。(二)宾变主,把 “是be”补,动词跟,变过(去)分(词)。 时与数, “是be”随主,时态随原句,莫变要记清。 主语代词变宾格,成为 “by” 之宾。(三)被动不离 “be”, “p.p
21、.”, 主谓一致莫忘记, 句中时态要留意,”进行”易漏一个 “be”。1) His wallet was stolen yesterday afternoon.2) A young man was beating a dog when I entered.= A dog was being beaten by a young man when.复合宾语变被动口诀复合宾语结构中,“感官” “使役”最常用。主动结构变被动,根据常规来使用。主动宾补是动原,变成被动则不然。原来宾补成主补,省去的 to 要还原。1) I found him lying on the floor.= He was fou
22、nd lying on the floor.2) His father let /made him stay at home alone.= He was let / was made to stay at home alone.感官使役感官使役动词用法口诀感使动词真奇怪,to 在句中象妖怪;主动句里 to 走开,被动句里 to 回来。1) We often hear her sing in the kitchen.= She is often heard to sing in the kitchen.2) His mother doesnt let him watch TV.He isnt
23、let to watch TV.不带to的不定式作宾补不定式不带 to,九个动词要记住。一听(hear)二看(see, watch)三感觉(feel, notice, observe),还有 make, let和 have。作宾补,是秃头;当主补时要带 to。含情态动词变被动方法主动句中含情动,变成被动很容易。情动加be加 “过(去)分(词)”,其他成分莫丢弃。若要熟悉运用它,必须经常来练习。1) You can not put your bike here.= Your bike can not be put here.2) I may do my homework a bit later.
24、= My homework may be done a bit later.虚拟语气用法巧记虚拟语气意虚幻,愿望事实总相反。所列条件是假设,亦表建议和委婉。假设条件在现在,具体事实没实现。从句使用过去时,主句动前 would 添。过去事实已存在,后来设想不一般。would 加上完成时,过去完成凑条件。表示将来可能性,小而又小很可怜。would 后面动词立,从句 should 加动原。wish 后接宾从句,主语想法难实现。从句虚拟分三种,现在将来谓语换。as if (as though) 来引导,情同 wish 宾从连。一个坚持俩命令,三个建议四请愿。所有从句都在数,虚拟 should 放动前。
25、虚拟语气经常用,莫与直陈混一谈。虚拟语气用法巧记一个坚持:两个命令:三个建议:四个要求:insistcommand, ordersuggest, advise, proposedemand, desire, request, require以上动词后的宾语从句中,以上动词后的宾语从句中,谓语为谓语为“(should) do”(should) do”形式,形式,“should” should” 可以省可以省略。略。1) If it were Sunday tomorrow, I should go to see a film.2) If I were you, I would go with h
