1、作业帮陈老师小学英语语法知识复习一、词类：(一)动词行为动词、be动词、情态动词。(1)行为动词原形、+s/es、+ed、+ing(2) be动词a、Am-was Is -was Are-were 口诀：我用 am,你用are, is用在他她它，所有复数全用are。b、肯定和否定句I am (not) from London. He /She is(not) a teacher. My hair is(not) long. Her eyes are(not) small.c、 般疑问句 Am I ？ Yes, you are. No, you aren you/theAre ? Yeswe/
2、they are.No,we/ they aren t. Is the cat fat? Yes, it is. No, it isn t.is、am are为一类，一般用于一般现在时、现在进行时和一般将来时中。was和were为另一类，一般用于一般过去时。(3)情态动词情态动词是一种本身有一定的词义，表示说话人的情绪，态度或语气的动词，但不能单独作谓语，只能和其他动词原形构成谓语。can、must、should may、will。情态动词后动词总是用原形。(不受其他任何条件影响)1. I / He / She / They can sing. May I come in? I must go
3、 now.2. You should be quiet in the library.3. You ll be good friends.(二)名词这里强调两点：不可数名词都默认为单数，所以总是用is或者was。单数名词表示一个可数事物，复数名词表示两个或两个以上的可数事物。一、 可数名词与不可数名词的区别普通名词所表示的人或事物是可以按个数计算的，这类名词叫可数名词。可数名词分为 个体名词(表示某类人或事物中的个体，如 worker, farmer, desk, factory等)和集体名词(表示作为一个整体来看的一群人或一些事物，如 people, family等)。如果普通名词所表示的事
4、物是不能按个数来计算的，这类名词就叫不可数名词。不可数名词分为物质名词（表示无法分为个体的物质，如 meat, rice, water, milk, orange等）和抽象名词（表示动作、状态、情况、 品质等抽象概念，如 work, homework, time, health, friendship 等）。二、可数名词复数形式1、名词复数有规律，一般词尾加 S;如：studentf students2、辅音字母加 y型，变y为i, es;如：babybabies3、元音字母加y型，直接加s;如：boyboys4、字母 o、s、x、ch、sh 结尾的名词，在其后加 es;如：bus-buses
5、; box- boxes5、F、fe真小气，字母 v来把它替，es在后别忘记；如：leaf leaves; knife knives6、字母。来真神奇，有生命的 es,无生命的加 s;如：tomat。一 tomatoes; photo fphotos7、中日好友来聚会，绵羊鹿鱼把家回；注：Chinese、Japanese people、sheep、deer、fish单复数本身。8、男士、女士 a 变 e;支口： manfmen; womanfwomen9、牙齿、脚、鹅，双 。变双 e;如：toothteeth; footfeet; goosegeese10、 孩子们想去天安门，原形后面ren;

18、示。基数词的用法:1 . 编号的事物用基数词: 如 :Lesson Five, Room 1012 .表示年 ,月 ,日 时用基数词。3 .表示几点钟, 几点过几分 用基数词。It is two to two. 现在是两点差两分。4 .加减乘除用基数词。One plus two is three. 一加二等于三。Eight minus four is four. 八减四等于四。Two times two is four. 二乘二等于四.Ten divided by two is five. 十除二等于五。5表示百分数用基数词.Thirty percent of them is water. 它
19、们当中有30%的水。6.表示分数时,分子数字用基数词, 但分母要用序数词, 如分子不是1,序数词要用复数形式。One-fifth of the books are mine. 五分之一的书是我的。Three-tenths of water is disappeared. 十分之三的水不见了。2)序数词：表示数目顺序的词用序数词。1 .序数词119除第一，第二，第三，第五，第八，第九，第十二变化不规则外，其余均由在基数词 后加上-th。2 .十位整数的序数词的构成方法是，是将十位整数基数词的词尾-y变成i再加-eth。3 .几十几的序数词，只是把个位数变成序数词，十位数不变。基数词和序数词互变曲
20、基变序，有规律，词尾加上th;一二三，特殊记，词尾字母t,d,d(first,second,third); 八减t(eighth), 九去 e (ninth) , f 来把 ve 替(five-fifth,twelve-twelfth); 单词 ty 作结尾，ty 变成 tie(twenty-twentieth);若是碰到几十几，只变个位就可以 (twenty-one-twenty-first).4 .第一百以上的多位序数词由基数词的形式变结尾部分为序数词形式来表示。one hundred and twenty-first , one thousand, three hundred and t
21、wentieth5 .序数词的缩写形式有时，序数词可以用缩写形式来表示。主要缩写形式有。firstlst second2nd third3rd fourth4th sixth6th twentieth20thtwenty-third23rd其中lst, 2nd, 3rd为特殊形式，其它的都是阿拉伯数字后加上th。6 .通常前面要加定冠词the;但是如果序数词前出现不定冠词a或an时，则表示 再“，又“.Weve tried it three times . Must we try it a fourth time?7 .基数词也可以表示顺序。 只需将基数词放在它所修饰的名词之后(名词需大写)即
22、可，不需要添力口定冠词。the first lessonLesson One , the fifth pagePage 5, the twenty-firstroomRoom 21一、：写出下列词的序数词1. one 2.two 3. six 4.five 5.nine _6.twelve 7.eight 8.twenty-one 二、写出下列单词的基数词1 .third _ 2.fourth 3.tenth 4.twentieth 5.nineteenth _ 6.thirty-first、根据句子意思填空。1.
