(1)名词100个 一、最常见的名词复数(Plural)就是在单数(Singular)名词后边加上一个s boy boys cat cats room rooms horse horses tree trees rose roses 二、如果名词是以sh,ch,s或x结尾的话,那就要在单数的后面加上es lash lashes 鞭子 push pushes branch branches match matches coach coaches 教练 gas gases ass asses 驴子 class classes box boxes fox foxes 三、如果名词结尾是一个子音(consonant,就是除了a,e,i,o,u之外的字母)加一个y, 那就要将y换成i,再加上es baby babies family families pony ponies city cities country countries 四、可是,如果名词结尾是一个母音(vowel,就是a,e,i,o,u)加一个y,那只要在单 数词后加一个s就成了 play plays way ways valley valleys 山谷 donkey donkeys toy toys boy boys guy guys 五、当单数名词的结尾是f或fe时,复数的写法就是将f改为v,再加es thief thieves shelf shelves leaf leaves calf calves half halves wolf wolves wife wives life lives 可是,f结尾的单数字,有许多只需加个s就成复数(你看,这又是英文的bugs) roof roofs hoof hoofs chief chiefs cliff cliffs gulf gulfs 六、结尾是o的单数词,一部份只加s就成复数词,但有的却需加es,真令人捉摸不定呀 piano pianos photo photos bamboo bamboos zoo zoos kangaroo kangaroos 袋鼠 mulatto mulattos 白黑混血儿 hero heroes mango mangoes potato potatoes volcano volcanoes negro negroes 黑人 cargo cargoes echo echoes buffalo buffaloes tomato tomatoes mosquito mosquitoes 七、由于古老传统的原因,一些单数词得加en才能变成复数词(鬼知道是什么原因): ox oxen child children (你看,这个就不守规矩了,不是加en ,是ren呀) brother brethren (哎呀,这个这个……是bre,不是bro) 八、一些单数词得改头换面一番,才能变成复数词的哦: analysis analyses 分析 basis bases 基础 datum data 数据 foot feet formula formulae/formulas 公式 goose geese louse lice 虱子 man men mouse mice medium media/mediums 媒介 memorandum memoranda/memorandums 备忘录 parenthesis parentheses 圆括号 phenomenon phenomena 现象 radius radii 半径 tooth teeth woman women 九、有些名词是单数、复数不分的,很可爱是吗。 deer fish cannon sheep salmon 鲑鱼 trout 鳟鱼 (许多鱼类都是这么"可爱"的呀。) 十、一些名词虽分单数、复数,但出现次数多的总是单数词: abscence clothing film help furniture 家具 machinery 机械 news scenery 风景 sugar traffic 交通 十一、另一些名词则以复数词出现的机会较多: bellows 风箱 clothes police shorts 短裤 scissors 剪刀 spectacles 眼镜 shears 大剪刀 trousers 长裤 wages 工资 十二、最后一类是compound nouns,这类复数词是以主要的名词来表示: coat-of-mail coats-of-mail 锁子甲 daughter-in-law daughters-in-law 媳妇 father-in-law fathers-in-law 岳父 man-of-war men-of-war 兵舰 maid-servant maid-servants step-son step-sons 晚子 son-in-law sons-in-law <><><><><><><><><><><><><><><><><><><><><><><><><> 名词复数的不规则变化 1)child---children foot---feet tooth---teeth mouse---mice man---men woman---women 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: deer,sheep,fish,cattle, deer, salmon, Chinese,Japanese li,jin,yuan,two li,three mu,four jin 但除人民币元、角、分外,美元、英镑、法郎等都有复数形式。
如: a dollar, two dollars; a meter, two meters 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: The Chinese are industries and brave. 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. <<一千零一夜>>是一本非常有趣的故事书。 5) 表示由两部分构成的东西,如:glasses (眼镜) trousers, clothes 若表达具体数目,要借助数量词 pair(对,双); suit(套); a pair of glasses; two pairs of trousers 6) 另外还有一些名词,其复数形式有时可表示特别意思,如:goods货物,waters水域,fishes(各种)鱼 (2动词)以下写出它们的现在分词和单三. be build buy can catch am,is choose come cost cut are dig draw drink drive beat fall feel find fly become forget freeze grow hang blow hear hide hit hold break hurt keep know lay bring leave lend let lie lose may mean meet mistake ride ring rise run say see sell send shall shine show shut sink sleep smell speak spend spill spit spoil stand steal sweep teach tell throw understand wake pay will win die 以下写出过去式和现在分词,单三. look start live hope use stop plan study carry worry talk snow wash ugree decide discuss shop wait travel walk turn cool need relax follow close help talk enjoy 解 be being is/am build building builds buy buying buys can (无)(无) catch catching catches am (无)(无) is(无)(无) choose choosing chooses come coming comes cost costing costs cut cutting cuts are(无)(无) dig digging digs draw drawing draws drink drinking drinks drive driving drives beat beating beats fall falling falls feel feeling feels find finding finds fly flying flies become becoming becomes forget forgetting forgets freeze freezing freezes grow growing growes hang hanging hangs blow blowing blows hear hearing hears hide hiding hides hit hitting hits hold holding holds break breaking breaks hurt hurting hurts keep keeping keeps know knowing knows lay laying lays bring bringing brings leave leaving leaves lend lending lends let letting lets lie lying lies lose losing loses may (无)(无) mean meaning means meet meeting meets mistake mistaking mistakes ride riding rides ring ringing rings rise rising rises run running runs say saying says see seeing sees sell selling sells send sending sends shall (无)(无) shine shining shines show slowing slows shut shutting shuts sink sinking sinks sleep sleeping sleeps smell smelling smells speak speaking speaks spend spending spends spill spilling spills spit spitting spits spoil spoiling spoils stand standing stands steal stealing steals sweep sweeping sweeps teach teaching teaches tell telling tells throw throwing throws understand understanding understands wake waking wakes pay paying pays will (无)(无) win winning wins die dying dies 写“无”的都是情态动词或者be动词,这些词没有现在进行时和单三 --Will (3)形容词比较级 英语形容词比较级 (一)一般句式的构成: A + is / are+ 形容词比较级+ than + B A 是主格 B 是宾格 如: She is taller than me. 主格 形容词比较级 宾格
(二)英语形容词比较级的构成 英语形容词比较等级有三个:原级,比较级和最高级。
形容词比较等级形式变化有规则的和不规则的两种。
规则变化 1)单音节词末尾加-er(比较级),-est(最高级)
【例】 原级 比较级 最高级 great greater greatest small smaller smallest clean cleaner cleanest 2)单音节如以e结尾,只加-r(比较级),-st(最高级)
【例】 fine finer finest nice nicer nicest wide wider widest 3)闭音节单音节词如末尾只有一个辅音字母,须先双写这个辅音字母,再加-er(比较级),-est(最高级)
【例】 big bigger biggest hot hotter hottest red redder reddest 4)少数以-y,-er,ow,-ble结尾的双音节词,末尾加-er(比较级),-est(最高级)。以-y结尾的词,如-y前是辅音字母,则变y为-i,再加-er和-est。以-e结尾的词只加-r和-st。
【例】 clever cleverer cleverest narrow narrower narrowest able abler ablest easy easier easiest 5)其它双音节和多音节词皆在前面加单词more和most。

【例】 careful more careful most careful difficult more difficult most difficult delicious more delicious most delicious 不规则变化 原级 比较级 最高级 good/well better best bad worse worst many/much more most little less least far farther/further farthest/furthest 注:有些形容词一般没有比较等级。如: right, wrong, woolen等。 形容词的比较等级的用法:比较级用于二者的比较。
【例】 Li Ping is older than Wang Hai. 李平比王海年纪大。
There are more students in Class One than in Class Two.一班比二班学生多。 虱子
