宝典训练英语·七年级·上册 课时3 语法 课时精讲 ●可数和不可数名词。 名词分为可数名词和不可数名词。可数名词能以数目来计算，可以分成个体的人或东西；因此 它有复数形式：不可数名词不能以数目来计算，一般没有复数形式，只有单数形式。 【解析1】怎么区分可数名词和不可数名词 【讲解】可数名词 可数名词有单、复数之分。一般来说，表示人或事物的名词和集体名词等一般都是可数的：能与 不定冠词a,an连用。如：aboy一个男孩；a desk一张课桌；a film一部电影：a story一个故事： a song一支歌；an apple一个苹果；我们可以在可数名词前用some,many,a lot of,afew等词或词 组表示数量的多少。如：some books,many trees,a few boys等。 【讲解2】不可数名词 不可数名词，通常只有一种形式，没有单复数的变化，所以不能和a,'an连用。如：water水，air 空气，music音乐，tea茶，meat肉，milk牛奶，rice米饭；我们可以在不可数名词前用some,much, a lot of,a little等词或词组表示数量的多少。如：some milk,some juice,some bread,a little water, much meat等。 【讲解3】不可数名词可以和量词连用。如：a bottle of water一瓶水；a piece of paper一张纸 【解析2】怎样变名词复数 在英语里面，名词分为可数名词(countable noun)和不可数名词(uncountable noun),不可数名 词没有单复数之分，用时只当单数词用；可数名词有单复数之分，单数可数名词的前面要用a或an。 如：a pencil,a basketball,a dictionary,an egg,an ID card;而复数即两个或两个以上的要作相应的 变化.情况如下： (1)特殊词，特殊变化，需单独记。 child-→children,man→men,foot→feet,woman→women tooth-teeth,sheep→sheep,deer→deer (2)一般的词在单数词后直接加“s”。 book--books,pen-pens,car--cars,map-maps,cartoon-cartoons (3)以s,x,sh,ch结尾的词加“-es”。 box--boxes,watch-watches 4444444 (4)以“辅音字母十y”结尾的名词去掉“y”,改成“”，再加“es”。 family→families,comedy→comedies (5)以f或fe结尾的词，先去掉f或fe,改成“v”,再加“-es”。 knife-"knives,wife-"wives,handkerchief-handkerchieves 64 Unit 3 The Earth there be句型。 (I)there be句型主要用以表达“某处（某时）有某人（某物）.。”其基本结构为“There be+某物（某人） +某地（某时）.”其中there是引导词，没有词义；主语是be后面的名词，be是谓语动词，在一般 现在时中be只用is和are两种形式。下面这首歌诀可帮你巧记there be句型结构： there be放句首，主语跟在后。地点，时间放句末，强调置前头。如： There is a book on the desk.桌子上有一本书。 有时为了强调地点，也可把介词短语放在句首。如： On the desk there is a book..桌子上有一本书。 (2)there be句型中的be动词如何确定呢？请先看看下面这首歌决： be动词，有三个，am,is还有are。“there be'”真特别，不留am只留俩，那就是is还有are。要用is 还是are,须看其后的名词是单数还是复数。若是单数或不可数名词用is,否则就用are。如： ①There is a tree behind the house,房子后面有一棵树。 ②There is some water in the bottle,瓶子里有一些水。 ③There are some pears in the box.箱子里有一些梨。 (3)注意：如果“be”后的主语是由and连接的两个或两个以上的名词，那么be的形式要遵循“远亲不 如近邻”的原则。也就是说，“be”的形式是由与它最近的那个名词来确定的。若那个名词是单数 或不可数名词要用is,是复数就用are。如： ①There is a book and some pens on the floor,.地板上有一本书和一些钢笔。 ②There are some pens and a book on the floor,地板上有一些钢笔和一本书。 【拓展】注意：若某人有…，应用have got.have或has got/.has表达。如： They have got/have many friends..他们有很多朋友。 She has got/has a nice bike.她有一辆漂亮的自行车。 过关 ●用所给名词的适当形式填空。 1.How many (sheep)are there on the hill? 2.There is some (food)in the basket. 3.The baby has only two (tooth)now. 4.There is a lot of (water)in the bottle. 5.There are five (people )in his family. 6.I have lots of (tomato)here. 7.The (leaf)on the tree turn yellow. 8.The (child)are playing games on the playground now. 9.Their (dictionary)look very new. 10.Can you give me some bottles of (orange),please? 65 宝典训第语·七年级·上册 色用be动词的正确形式填空。 1.There two boxes of toys in the room. 2.Water very important in our daily life. 3.What those? 4.They going to have lunch together. 5.1 studying English now. 6.There a blackboard on the wall. 7. there any water in the cup? 8.There a glass of milk and two eggs on the table. 9.There three pieces of chocolate in the box. 10.There some sheep on the hill.
