Is there + 可数名词单数/不可数名词 + 地点/时间状语?如: 肯定回答:Yes, there is. 否定回答:No, there isn’t. Is there a pen in the pencil case? 笔袋里有一支钢笔吗? Is there some orange juice in the glass?玻璃杯里有一些橘子汁吗? 2. Are there + 可数名词复数 + 地点/时间状语?如: 肯定回答:Yes, there are. 否定回答:No, there aren’t. There are a lot of books in the bookcase. 书架上有许多书。 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 is a book and two pens on the desk (“a book” 是单数,be 动词用 is ) There are two pens and a book on the desk .(“two pens” 是复数,be 动词用 are) 小练笔 单项选择。 ( )1.______ there ______ mountains in the park?

Let’s go to the computer room. 参考答案 一、用Be there的正确形式填空 1. 答案:Is there 解析:主语“a computer room”是单数,be动词用Is;句子表疑问,结构为“Is there+单数名词+地点”。 2. 答案:Are there 解析:主语“any other rooms”是复数,be动词用Are;疑问句中用“Are there+复数名词+地点”。 3. 答案:Is there 解析:答语是“Yes, there is”,问句需与答语的be动词一致,用Is there(主语“a piano”是单数)。 4. 答案:Are there 解析:主语“two playgrounds”是复数,be动词用Are;疑问句结构为“Are there+复数名词+地点”。 5. 答案:Are there 解析:主语“any swings”是复数,be动词用Are;疑问句中“any”搭配复数名词,用Are there。 二、单项选择 1. 答案:B 解析:表示“第几层楼”用序数词,one的序数词是first;“on the first floor”意为“在一楼”。 2. 答案:A 解析:主语“a library”是单数,be动词用Is;there be疑问句的答语需“be动词一致”,肯定答语为“Yes, there is”。 3. 答案:B 解析:表“第几层”用序数词,three的序数词是third;序数词前加the(此处“on the third floor”省略the不影响,核心选序数词)。 4. 答案:A 解析:句意为“她穿红裙子看起来很漂亮”,“看起来”用looks(系动词,后接形容词beautiful);likes(喜欢,表动作)、looks like(像……,后接名词/代词)均不符。 5. 答案:A 解析:固定搭配“have a look”意为“看一看”,look是辅音音素开头,用a修饰。 6. 答案:B 解析:答语是“在二楼”,问句询问“哪一层”,用Which floor;What(什么)、Where(哪里)均不搭配floor。 7. 答案:C 解析:show是动词,后接人称代词宾格;I(主格)、my(形容词性物主代词)均不符,me(宾格)正确。 8. 答案:A 解析:there be句型遵循“就近原则”,靠近be动词的“a swing”是单数,be动词用is。 9. 答案:B 解析:表“第五个生日”用序数词,five的序数词是fifth;fiveth是错误拼写。 10. 答案:C 解析:句意为“音乐听起来很好听”,“听起来”用sound(系动词);主语“the music”是单数,sound变sounds;listens(听,表动作,需加to)不符。 三、句型转换 1. 答案:Is there 解析:there be单数句变疑问句,把Is提到句首,其余不变。 2. 答案:aren’t any 解析:there be复数句变否定句,在are后加not(aren’t);疑问句/否定句中some变any。 3. 答案:Which floor 解析:划线部分“the second”表“第几层”,用Which floor提问“哪一层”。 4. 答案:No, there isn’t 解析:there be单数疑问句的否定答语为“No, there isn’t”,需保持be动词一致。 5. 答案:How many; are there 解析:划线部分“three”表数量(可数名词),用How many提问;后接“are there”构成完整问句。 四、改错题 1. 错误:are→改正:is 解析:主语“a computer”是单数,there be需“单对单、复对复”,be动词用is。 2. 错误:one→改正:first 解析:表“第几层楼”用序数词,one是基数词(表数量),需改为序数词first。 3. 错误:some→改正:any 解析:疑问句中表“一些”用any,some常用于肯定句,此处需替换为any。 4. 错误:third前缺the→改正:on the third floor 解析:序数词前通常加the,“在三楼”正确表达是“on the third floor”,需补the。 5. 错误:Is→改正:Are 解析:主语“two playgrounds”是复数,there be需“复对复”,be动词用Are。 五、选择合适的选项补全对话 1. 答案:B 解析:答语是“Yes, there is”,问句需为“Is there...”结构,选项B(你们学校有图书馆吗)符合。 2. 答案:D 解析:答语是“在二楼”,问句需询问地点,选项D(美术室在哪里)符合。 3. 答案:A 解析:答语是“No, there aren’t”,问句需为“Are there...”结构,选项A(音乐室里有电脑吗)符合。 4. 答案:E 解析:上句提到“电脑室有电脑”,下句答语“去三楼”,选项E(我们去电脑室吧)衔接合理。 5. 答案:C 解析:上句是“Thank you”,回应感谢用“You’re welcome”,选项C符合。 第 1 页 共 14 页 学科网(北京)股份有限公司 $
