篇二:[leaf的复数形式]英语手抄报图片大全初一


  从全世界来看,说英语的人数已经超过了任何语言的人数,10多个国家以英语为母语,45个国家的官方语言是英语,世界三分之一的人口(二十几亿)讲英语。那么我们哪里有不学习的道理呢?

  初一英语语法
  1、名词
  A)、名词的数
  我们知道名词可以分为可数名词和不可数名词,而不可数名词它没有复数形式,但可数名词却有单数和复数之分,复数的构成如下:
  一)在后面加s。如:fathers, books, Americans, Germans,apples, bananas
  二)x,sh, ch, s, tch后加es。如:boxes,glasses, dresses, watches, wishes, faxes
  三)1)以辅音字母加y结尾的变y为i再加es 如:baby-babies, family-families,duty-duties, comedy-comedies, documentary-documentaries, story-stories
  2)以元音字母加y结尾的直接加s。如:day-days,boy-boys, toy-toys, key-keys, ways
  四)以o结尾加s(外来词)。如:radios, photos, 但如是辅音加o的加es:如: tomatoes西红柿, potatoes马铃薯
  五)以f或fe结尾的变f为v再加es(s)。如:knife-knives, wife-wives,half-halves, shelf-shelves, leaf-leaves, yourself-yourselves
  六)单复数相同(不变的)有:fish, sheep, deer鹿子, Chinese, Japanese
  七)一般只有复数,没有单数的有:people, pants, shorts, shoes, glasses, gloves, clothes, socks
  八)单词形式不变,既可以是单数也可以是复数的有:police警察局,警察, class班,同学, family家,家庭成员
  九)合成的复数一般只加主要名词,多数为后一个单词。如:action movie-action movies, pen pal-pen pals; 但如果是由man或woman所组成的合成词的复数则同时为复数。如:man doctor-men doctors, woman teacher-women teachers
  十)有的单复数意思不同。如:fish鱼 fishes鱼的种类,paper纸 papers报纸,卷子,论文, work工作 works作品,工厂, glass玻璃glasses玻璃杯,眼镜, orange桔子水 oranges橙子, light光线lights灯, people人 peoples民族, time时间 times时代, 次数, chicken 鸡肉 chickens小鸡
  十一) 单个字母的复数可以有两种形式直接加s或’s。如:Is (I’s), Ks (K’s)。但如是缩略词则只加s。如:IDs, VCDs, SARs
  十二) 特殊形式的有:child-children, man-men, woman-women, foot-feet, mouse-mice,policeman-policemen, Englishman-Englishmen
  B)名词的格
  当我们要表示某人的什么东西或人时,我们就要使用所有格形式。构成如下:
  一)单数在后面加’s。如:brother’s, Mike’s, teacher’s
  二)复数以s结尾的直接在s后加’,如果不是以s结尾的与单数一样处理。如:Teachers’ Day教师节,classmates’; Children’s Day六一节, Women’s Day三八节
  三)由and并列的名词所有时,如果是共同所有同一人或物时,只加最后一个’s,但分别拥有时却分别按单数形式处理。如:Mike and Ben’s room迈克和本的房间(共住一间),Mike’s and Ben’s rooms迈克和本的房间(各自的房间)

  2、代词
  项目人称代词 物主代词 指示代词 反身代词
  人称 主格 宾格 形容词 名词性
  第一人称 单数 I me my mine myself
  复数 we us our ours ourselves
  第二人称 单数 you you your yours yourself
  复数 you you your yours yourselves
  第三人称 单数 she her her hers herself
  he him his his himself
  it it its its this that itself
  复数 they them their theirs these thosethemselves
  3、动词
  A)第三人称单数
  当动词是第三人称单数时,动词应该像名词的单数变动词那样加s,如下:
  一)一般在词后加s。如:comes, spells, waits, talks, sees,dances, trains
  二)在x,sh, ch, s, tch后加es。如:watches,washes, wishes, finishes

  2)以元音字母加y结尾的直接加s。如:plays, says, stays, enjoys, buys
  四)以o结尾加es。如:does, goes
  五)特殊的有:are-is, have-has

  B)现在分词
  当我们说某人正在做什么事时,动词要使用分词形式,不能用原形,构成如下:
  一)一般在后加ing。如:spell-spelling, sing-singing,see-seeing, train-training, play-playing, hurry-hurrying, watch-watching,go-going, do-doing
  二)以不发音e的结尾的去掉e再加ing。如:dance-dancing, wake-waking, take-taking, practice-practicing,write-writing, have-having
  三)以重读闭音节结尾且一个元音字母+一个辅音字母(注意除开字母组合如show –showing, draw-drawing)要双写最后的辅音字母再加ing。如:put-putting, run-running, get-getting,let-letting, begin-beginning
  四)以ie结尾的变ie为y再加ing。如:tie-tying系 die-dying死 lie-lying 位于
  4、形容词的级
  我们在对两个或以上的人或物进行对比时,则要使用比较或最高级形式。构成如下:
  一) 一般在词后加er或est(如果是以e结尾则直接加r或st)。如:greater-greatest,shorter –shortest, taller –tallest,longer –longest, nicer- nicest, larger -largest
  二)以重读闭音节结尾且1个元音字母+1个辅音字母(字母组合除外,如few-fewer fewest)结尾的双写结尾的辅音再加er /est。如:big-bigger biggest, red-redder reddest, hot-hotter hottest
  三) 以辅音字母+y结尾的变y为i加er/est。如:happy-happier happiest,sorry-sorrier sorriest, friendly-friendlier friendliest(more friendly mostfriendly), busy-busier busiest, easy-easier easiest
  四)特殊情况:(两好多坏,一少老远)
  good/well -better best many/much - more most  bad/ill– worse worst
  little- lessleast old- older/elder oldest/eldest far- farther/further farthest/furthest
  5、数词 (基变序,有规则;一、二、三,自己背;五、八、九、十二;其它后接th;y结尾,变为i, eth跟上去。)first, second, third; fifth, eighth, ninth, twelfth; seventh, tenth,thirteenth, hundredth; twenty-twentieth, forty-fortieth, ninety-ninetieth

篇三:[leaf的复数形式]初中名词练习题及答案

  在英语的学习中,名词的掌握是一项重点的内容,接下来小编搜集了初中名词练习题及答案,仅供大家参考,希望帮助到大家。
  初中名词练习题及答案一
  1.、Lucy and Lily___in the same class.
  A.     am  B. is  C. are  D. be
  [答案]C.
  [析]由and连接两个单数名词作主语时应按复数名词来搭配谓语动词。
  2、 Which is the ___to the bus stop, please?
  A  road B  way C street D address
  [答案]B.
  [析]这是考察同意词辨析,road是指较宽阔的大道,意为“乡间公路”,而street意为道路两边的建筑物较高,可视为街道之意,而way则多为要到达某地所要经过的途径,还可引深为方式、方法。而address则为“地址”。如:There is a car running along the country road. I live at 105 Park street. Can you show me the way to the National Museum?
  3、Hurry up!There is___ time left.
  A little  B  a little  C  few  D  a few
  [答案]A.
  [析]因time作为时间讲为不可数名词,所以不可用few,a few来修饰。另外,英文的表达法与中文不同,中文讲,快点,时间不多了,而英文要讲,快点,没时间了。因此,要用little而不用a little.
  4、 How many ___can you see in the picture?
  A tomatos   B tomatoes  C   tomato  D the tomato
  [答案]B.
  [析]用How many提问时,其名词要用复数形式,而tomato的复数要加es.
  5、— ___is the meat. Please?
  — Ten yuan a kilo.
  A  How much  B How many  C How old   D How long
  [答案]A.
  [析]由对话的答语可看出其问句问的是价格。钱数作为整体、价格讲时,不论其值是多少都是不可数名词,要用how much 提问。
  6、The boy"s name is James Allen Green. So his given name is___.
  A  James Allen  B  Allen Green  C  James Green  D  Mr. Green
  [答案]A.
  [析]英文的习惯与中文不同,中文是姓在前名字在后,而英文则是姓在最后,其第一个名字是由父母所起的,中间的名字可能是父母、教父所起的,但都可称作given name,而姓在英文中是family name.
  7 、Shanghai is one of the biggest___in our country.
  A  city   B  city"s   C   citys    D   cities
  [答案]D.
  [析]复音字母以y结尾的单词的复数形式要把y变成i再加es。one of 加名词的结构中的名词应用复数。
  8 、Would you please pass me___?

  C two pieces of paper  D two pieces of papers
  [答案]C.

  16、There are three___and seven___in the picture.
  A  deers,  sheeps   B deers, sheep
  C deer, sheep   Ddeer,  sheeps

  A  my       B  Kike"s and John"s

  1.(2015·江苏,32)Some schools will have to make__adjustments__(adjust) in agreement with the national soccer reform.

  解析:句意:……对我们大多数人来说,这些变化很缓慢,而且就像清理被污染的河流,需要很多努力和工作。所填词作主语,其前是定冠词,所以应为名词;根据谓语动词are可知应用复数形式。

  解析:句意:父母一直很重视让我接受好的教育。attach importance to“认为……很重要;重视”。

  解析:句意:我感到无比自豪的是卓有成效地度过了我的岁月,忠实地为后代保存一份关于旅途详情的记录。分析句子结构可知,空格前有不定冠词和形容词detailed,所以要用名词单数形式。
  9.Your__performance__(perform) as a student will be excellent if you develop a habit of reflecting on how you learn.
