Unit 1 We are friends 专题02 语法提升·易错题专项训练 高频易错点03 祈使句的用法 高频易错点01 there be的用法 高频易错点02 情态动词can的用法 高频易错点、易错点提示、小练笔、答题点拨 易错精讲 there be用法 高频易错点01 there be结构表示在某地存在某物(某人)或者某时发生某事。 一、there be 结构的肯定句形式 1. There is + 可数名词单数/不可数名词 + 地点/时间状语。如: There is a pen in the pencil case. 笔袋里有一支钢笔。 There is some orange juice in the glass. 玻璃杯里有一些橘子汁。 2. There are + 可数名词复数 + 地点/时间状语。如: There are a lot of books in the bookcase. 书架上有许多书。 3. there be句型中be动词的确定 在there be 结构中,be动词在人称和数上要与后面的主语保持一致。 (1)主语是可数名词单数或者不可数名词时,be动词用is。 (2)主语是可数名词复数时,be动词用are。 (3)如句子中有几个并列的主语,be动词的形式要由最靠近be动词的那个名词决定,简称“就近原则”。 二、there be 结构的否定句形式 1. be动词后面加not,表示“没有”。some改为any,其余不变。如: There is not a bird in the tree. 树上没有一只鸟。 There are not any vegetables in the basket. 篮子里没有蔬菜。 注意:is not = isn't, are not = aren't 2. be动词的后面加上no,表示“没有”。如: There is no bird in the tree. 树上没有鸟。 There is no juice in it. 它里面没有果汁。 There are no vegetables in the basket. 篮子里没有蔬菜。 注意:否定句的两种表达方式可以互换。如: There aren't any books on the desk. 书桌上没有书。 易错点提示 1. there be句型 与 have的区分 there be句型:强调在某个地点或时间“存在”某人或某物,不强调所属关系。 There was a pen on the desk.(桌子上有一支钢笔。),重点说明桌子上存在一支钢笔这个事实。 have:表示“拥有”,强调所属关系,即某人或某物归某人所有,主语通常是“人或物”。 I have a new book.(我有一本新书。),表明新书是“我”所拥有的。 2.there be句型的“就近原则” There be 句型遵循“就近一致”原则,即当 There be 后出现多个名词时,be 动词需和距离它最近 的名词在单复数上保持一致 。 There was a book and two pens on the desk just now.(“a book” 是单数,be 动词用 was ) There were two pens and a book on the desk just now.(“two pens” 是复数,be 动词用 were ) 小练笔 单项选择。 ( )1.There ______ any trees or flowers on the hill. A.are B.aren't C.isn't ( )2.There _______ an orange and some pears on the table. A.am B.is C.are ( )3.There ______ a desk and two chairs.

B 解析:any表否定,trees是复数,用aren't。 2. B 解析:就近原则,an orange是单数,用is。 3. C 解析:就近原则,a desk是单数,用is。 4. B 解析:my aunt(三单)用has;many flowers(复数)用there are。 5. A 解析:soup不可数,用is。 情态动词can的用法高频易错点02 1. 肯定句 结构:主语 + can + 动词原形 + 其他 She can speak English.(她会说英语。) 2. 否定句 结构:主语 + can + not(缩写为can't) + 动词原形 + 其他 He can't swim.(他不会游泳。) 3. 一般疑问句 结构:Can + 主语 + 动词原形 + 其他? 答语:肯定回答(Yes, 主语 + can.);否定回答(No, 主语 + can't.) —Can you play chess?(你会下棋吗?) —Yes, I can.(是的,我会。)/ No, I can't.(不,我不会。) 4. 特殊疑问句 结构:特殊疑问词(What/Who/Where等) + can + 主语 + 动词原形 + 其他? What can they do?(他们能做什么?) Where can we go?(我们可以去哪里?) 易错点提示 can 是情态动词,意为“可能,会,能”,没有人称和数的变化,can 后面接“动词原形”。 My brother can play basketball well. 我弟弟篮球打的很好。 小练笔 单项选择。 ( )1. —______ you swim? —Yes, I can. A. Do B. Can C. Are ( )2.

A. do B. can C. is 点拨 1. 答案:B 解析:答语用“can”,问句需用“Can”提问能力,Do/Are不符合答语逻辑。 2. 答案:A 解析:表“会唱英文歌”的能力,用情态动词“can”,is/does不能表能力。 3. 答案:B 解析:“Can”开头的否定回答固定用“can't”,can表肯定、isn't搭配错误。 4. 答案:A 解析:表“可以踢足球”的许可/能力,用“can”,are/do不能表此含义。 5. 答案:B 解析:答语用“can”,问句需用“can”提问“会做什么”,do/is不符合答语逻辑。 祈使句的用法高频易错点03 一、祈使句概念 1. 用于表达命令、请求、建议、劝告或禁止等的句子 2. 主语“You”通常被省略,一般以动词原形开头 3. 可在句首或句末加上Please表示礼貌 4. 句末用感叹号或者问号,用降调来读 二、祈使句类型 肯定祈使句 (1)Do型:动词原形开头 ,eg:Come on, please. (2)Be型:Be+形容词 ,eg: Be quiet. (3)Let型:Let+宾语+动词原形 ,eg: Let me help you. 否定祈使句 (1)Do型和Be型:在句首加Don't或never ,eg:Don't be careless. (2)Let型:Let+宾语+not+动原 或Don't+let+宾语+动原 , eg:Let's not say anything.

Are there 参考答案 一、用there be的正确形式填空 1. There is 解析:there be句型遵循“就近原则”,靠近be动词的“a pen”(单数)决定be动词用is,句首首字母大写,故填There is。 2. Is there 解析:“any”常用于否定句和疑问句,“milk”是不可数名词,疑问句需将be动词is提前,句首首字母大写,故填Is there。 3. There are 解析:“some books”(复数)作主语,be动词用are,句首首字母大写,故填There are。 4. There is 解析:“a dog”(单数)作主语,be动词用is,句首首字母大写,故填There is。 5. There are 解析:“any apples”(复数)作主语,be动词用are,否定形式直接在are后加not(可缩写为aren't),句首首字母大写,故填There are(或There aren't)。 二、单项选择 1. A 解析:there be句型遵循“就近原则”,靠近be动词的“a book”(单数)决定be动词用is;have表“拥有”,不能与there搭配,are用于复数主语,故选A。 2. B 解析:答语用“can”,问句需用“Can”提问能力;Do用于实义动词的疑问,Are用于主系表结构的疑问,均不符合答语逻辑,故选B。 3. A 解析:此句是肯定祈使句,以动词原形开头;Closes是动词三单形式,Closing是现在分词,均不符合祈使句结构,故选A。 4. B 解析:“any”表否定,“water”是不可数名词,be动词用is,否定形式为isn't;are用于复数主语,故选B。 5. C 解析:“Can”开头的一般疑问句,否定回答固定用“No, 主语+can't”;A选项用is回答can的提问,B选项“can”与“No”矛盾,故选C。 6. A 解析:否定祈使句“Don't”后接动词原形;swims是动词三单形式,swimming是现在分词,均不符合规则,故选A。 7.

A 解析:“Let's”后接动词原形,表“让我们一起做某事”;plays是动词三单形式,playing是现在分词,均不符合搭配规则,故选A。 10. B 解析:否定祈使句的正确结构是“Don't+动词原形”;Not不能单独引导否定祈使句,Isn't用于主系表结构的否定,故选B。 三、句型转换 1. Is there 解析:there be句型变一般疑问句,需将be动词提前,原句be动词是is,故填Is there。 2. can't draw 解析:情态动词can的否定形式是can't,后接动词原形,故填can't draw。 3. Don't open 解析:肯定祈使句变否定形式,在动词原形前加Don't,原句动词是open,故填Don't open。 4. aren't any 解析:there be句型变否定句,be动词are后加not(缩写为aren't),some在否定句中改为any,故填aren't any。 5. Can you 解析:情态动词can的一般疑问句,需将can提前,主语we改为you(疑问句中常将第一人称改为第二人称),故填Can you。 6. not go 解析:“Let's”开头的祈使句变否定形式,在动词原形前加not,故填not go。 四、改错题 1. 改正:There is a ruler on the desk. 解析:“a ruler”(单数)作主语,there be句型的be动词需用is,are用于复数主语,故将are改为is。 2. 改正:Can you swim? 解析:情态动词can后接动词原形,swims是动词三单形式,故将swims改为swim。 3. 改正:Let's play games together. 解析:“Let's”后接动词原形,playing是现在分词,故将playing改为play。 4. 改正:There are some oranges in the box. 解析:“some oranges”(复数)作主语,there be句型的be动词需用are,is用于单数/不可数名词,故将is改为are。 5. 改正:Don't talk loudly in the cinema. 解析:否定祈使句“Don't”后接动词原形,talking是现在分词,故将talking改为talk。 五、选择合适的选项补全对话 1. A 解析:句意为“那边有一只猫”,表“存在”用there be句型,“a cat”(单数)决定be动词用is,且此处是肯定句,故选A。 2. B 解析:答语用“can”,问句需用“Can”提问能力,Do用于实义动词的疑问,Are用于主系表结构的疑问,故选B。 3. B 解析:句意为“让我们去看看吧”,“Let's”(Let us的缩写)后接动词原形,表提议,Let后需接宾语,Lets是错误形式,故选B。 4. B 解析:句意为“请别碰它”,否定祈使句用“Don't+动词原形”,Not不能单独引导,Isn't用于主系表结构的否定,故选B。 5. A 解析:答语用“there isn't”,问句需用“Is there”(there be句型的一般疑问句),“food”是不可数名词,be动词用is,故选A。 第 1 页 共 14 页 学科网(北京)股份有限公司 $
