1、在此处键入在此处键入小学英语语法知识点汇总一、 名 词表示某一事物，有具体的和抽象的之分。分为可数名词和不可数名词。强调：不可数名词都默认为单数，所以总是用 is 或者 was；最好不要根据 some、any、a lot of 等词去作判断，以免受误导。 1、可数名词如何变“复数形式”：a一般情况下，直接加 -s，如：book-books, bag-bags, cat-cats, bed-beds ；读音：清辅音后读 s， 浊辅音和元音后读z。b以 s. x. sh. ch 结尾，加-es，如：bus-buses, box-boxes, brush-brushes, watch-watches

2、 ；读音：iz。c以“辅音字母+y”结尾，变 y 为 i, 再加-es，如： family-families, strawberry-strawberries ；读音：z。d以“f 或 fe”结尾，变 f 或 fe 为 v, 再加-es，如：knife-knives ，thief-thieves ；读音：z。e以“o”结尾的词，分两种情况1）有生命的+es 读音：z 如：mango-mangoes tomato-tomatoes hero-heroes2) 无生命的 +s 读音： z 如：photo-photos radio-radiosf. 不规则名词复数： man-men, woman-w

3、omen, policeman-policemen, policewoman-policewomen, snowman-snowmen, mouse-mice, child-children, foot-feet, tooth-teeth, fish-fish, people-people, Chinese-Chinese, Japanese-Japanese 2、不可数名词没有复数。如果要计算不可数名词所表达的数量，就得在数词和不可数名词之间加上“量词+of”。例如：a glass of water, a piece of paper, a bottle of juice判断步骤：如是 am

6、e-mail, an orange, an old man, an English watch, an hour2、定冠词：the。用在单数或者复数名词前。the 没有具体意思，有时翻译为这、那。它的基本用法：（1）用来表示特指某（些）人或某（些）事物。如：The map on the wall is new.（2）表示说话者双方都知道的人或事物。如：Look at the picture, please.（3）表示再次提到前面谈过的人或事物。如：This is a stamp.

9、入在此处键入三 数 词我们学过两类：基数词和序数词。基数用于表示数量多少，而基数词用于表示次序，常在日期中出现。区别：基数词前面没有“the” ；序数词前一定要有“the”。1、超过二十以上的两位数需要在个位和十位之间加上“-”。如：21 twenty-one2、三位数以上的则需要在百位数后再加上 and。如：101 a/one hundred and one3、用基数词来修饰可数名词时，一定别忘了它的复数形式。如：十八个男孩 eighteen boys4、用基数词修饰不可数名词时，如是复数，变它的量词为复数。如：两碗米饭 two bowls of rice5、序数词一般加“th”，特殊的有：

10、first, second, third, fifth, eighth, ninth, twelfth 以及二十及二十以外的整十：twentieth, thirtieth, fortieth “第几十几” ：前面整十不变，后面“几”改为序数词。如：88 eighty-eighth练一练1、请翻译下列短语。 （1）60 名学生 （2）15 本英语书 （3）九杯凉水 （4）4 个孩子 （5）12 月 31 （6）6 月 2 日 （7）第九周 （8）40 年前 （9）11+7 （10）上学第一天 2、把下列基数词改成序数词。one- two- three- nine- fourteen- twent

11、y- thirty-five- eighty-one在此处键入在此处键入四、代 词代词有两种：人称代词和物主代词。1、人称代词分为：第一、第二、第三人称，且有单复数之分。2、人称代词的主格在句中做主语，一般用在动词前（疑问句除外）；宾格在句中做宾语，多用于动词、介词后。3、形容词性物主代词起形容词的作用，后面一定要跟名词，表示该名词是属于谁的。4、名词性物主代词=形容词性物主代词+ 名词。如：This is my bag. = This is mine. That is her ruler. = That is hers.一般看后面有没有名词，如有，就用形容词性物主代词；如无，就用名词性物主代

17、heavier, early - earlier（4）双音节和多音节词的比较级应在原级前加 more 构成。如：beautiful - more beautiful, careful - more careful, quietly - more quietly, interesting - more interesting（5）有些不规则变化的，须逐一加以记忆。如：good/well better, bad/ill worse, many/much more, far farther/further, old older/elder练一练1、写出下列形容词、副词的比较级。big good lo

25、you do on the Spring Festival? 七、动 词这里所说的动词是指各种动词总称，其中包括 be 动词 、情态动词、助动词、行为动词（就是我们平时总说的那种动词）。动词、名词和形容词不太容易区分，如不能一眼看出，可用如下方法：先用“一（量 词）” （如：一个、一张等）和这个词连起来说，如说得通，一般认为是名词；说不通再用“很”去判断，就是把“很” 和为个词连起来说 ，说得通一般就是形容词；都说不通就是动词。 （目前我 们学过的，以后可能不同）（另外一些很明显的，如人称代 词、数词、情态动词等一下就可以知道）1、be 动词（ am, is, are, was, were ）

26、1）amwas, 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。2）肯定和否定句 I am (not) from London. He is(not) a teacher. She is(not) in the dining room. My hair is(not) long.

30、There _ a boy, two girls, three men and ten women in the park. 2、助动词（ do, does, did ）do, does 用于一般现在时，其过去式 did 用于一般过去时。它们通常用在疑问句和否定句中。它们的否定形式：do not = dont, does not = doesnt, did not = didnt。注意：在一般现在时中，does 用于第三人称单数，其余一律用助动词 do；助动词 do, does, did 后面一定要用动词原形。练一练1、用适当的助动词填空。1) _you like this magazine?

A B C ( ) 4) Do Jim get up at six everyday?在此处键入在此处键入A B C( ) 5) Dont giving the ball to Liu Tao.A B C3、情态动词情态动词也是一类特殊的动词，平时我们不把它说成是动词。情态动词可以和行为动词同时出现在同一个句子中。我们现在学过的情态动词有：can 、could、shall、should、will、would、may、might 、must 。注意：情态动词后动词总是

34、用原形。 （不受其他任何条件影响）其否定形式：can not = cant, must not = mustnt, 注意：may not 和 shall not（无缩写形式）练一练选择填空。( ) 1) The sign on the wall means you _stay away from the building.A. must B. cant C. shouldnt( ) 2) How many books _ you see on the desk?

36、过它们的四种形式：原形、第三人称单数+s/es、现在分词（也叫动名词）+ing 、过去式+ed。（1）动词第三人称单数变化规则：A、一般直接加“s”，如：play plays, visit visits, speak speaks ；B、以 “s”， “x”， “sh”， “ch”结尾时，加 “es”，如：catch catches, watch watches ；C、以 “辅音字母+y”结尾时，变 “y”为“i” 再加“es” ，如： carry carries, study studies 。（2）现在分词（动名词）构成规则：A、一般直接加“ing”，如： go going, do doi
