Underline the noun after is / are in each sentence. A. There is a bottle near the rock. B. There are three bags on the sand. C. There is some rubbish by the water. D. There is some paper in the blue bin. E. Is there any water in the bottle? Yes, there is. F. Are there any fish bones in the bag? No, there aren’t. Find and sort Examples from the notes a single countable thing 单个可数事物 ________________________________ more than one countable thing 可数复数 ________________________________ uncountable nouns 不可数名词 ________________________________ 1. Complete the rule: There is + a singular noun or an __________ noun. There are + a __________ noun. 2. Turn a statement into a question: move ______ / ______ before there. 3. Add ______ after is / are to make a negative sentence. 4. Why does “some rubbish” take is, but “some bags” take are? ________________________________________________________________________ 二 哪个才是决定因素 5分钟 5. Circle is or are. Underline the noun that helps you choose. a. There (is / are) a lot of paper in the box. b. There (is / are) a lot of bottles in the box. c. There (is / are) two pieces of paper on the desk. d. There (is / are) a plastic bag near the chair. 发现：a lot of不是决定is / are的词；要看它后面的________。 小提醒：本课paper指“纸”，rubbish指“垃圾”，均不可数；a piece of paper是一张纸。 三 让规则经得起检查 10分钟 6.

Beach record Number or amount plastic bottles 6 fish bones 0 clean water in the bottle some rubbish by the gate none a. ______ there any plastic bottles?

There (is / are) a bottle and two bags near the rock. b. There (is / are) two bags and a bottle near the rock. c. There (is / are) some paper and three bottles in the bin. 按教材规则，两个名词并列时，先看紧靠be后面的名词。圈出三个句子的这一名词。 表达提示：写作中也可以拆成两句，使信息更清楚；本题先按教材的邻近一致模式练习。 五 完成海滩清理报告 8分钟 The table shows the beach before and after a clean-up. Compare the two columns. Item on the beach Before After plastic bottles 6 0 plastic bags 3 0 paper some none a rubbish bin 0 1 9.

Complete the sentences without looking back. a. There ______ some clean water in the cup. b. There ______ two bottles on the desk. c. ______ there any paper in the box? No, there ______. d. “There have many trees” should be “____________________________”. 我最需要再检查的一项：[ ] 可数与不可数 [ ] is / are [ ] 问句与答句 选做：Rewrite “There is a bag and three bottles” as two short sentences. ________________________________________________________________________ 参考答案与易错点说明 教材对应：第57—58页。核心活动共40分钟；板书优先突出“圈名词→判断数→选be”，不先给学生堆叠完整规则。 分类：a bottle；three bags / fish bones；rubbish / paper / water。 1. uncountable；plural。2. is；are。3. not。4. rubbish是不可数名词，bags是可数名词复数；some不决定be的形式。 5. a is（paper）；b are（bottles）；c are（pieces）；d is（bag）。发现填“名词”。two pieces of paper的中心词是pieces。 6. a Are / are；b Are / aren’t；c Is / is；d Is / isn’t。肯定简短回答写Yes, there is，不写Yes, there’s。 7. a There are six bottles on the beach. b There is some rubbish near the gate. c Is there a bag under the chair? d There aren’t any bottles in the box. e have表示“某人拥有”；there are表示“某处有／存在”。 8. a is（a bottle）；b are（two bags）；c is（some paper）。此处按照教材第57页示例处理，不延伸为所有正式语境的唯一表达方式。 9. 示例：Now, there is a rubbish bin on the beach. There aren’t any plastic bottles. 也可用There isn’t any paper / There aren’t any plastic bags。 10. 示例：Are there any plastic bags on the beach now? No, there aren’t. 或 Is there a rubbish bin on the beach now? Yes, there is。 11. 示例：There is a rubbish bin on the beach now. There aren’t any plastic bottles. Please put rubbish in the bin. We need a clean beach because rubbish can harm sea animals. 12. a is；b are；c Is / isn’t；d There are many trees。选做：There is a bag. There are three bottles。 报告评价 每项1分 事实与After列一致；肯定或否定句准确；疑问句与短答匹配；建议与环保情境有关。句子内容合理且表达准确即可，不要求统一答案。 用错误决定下一步 错在some rubbish：回到分类；错在There have：对比“谁拥有”与“哪里存在”；错在Are there a bag：圈出a bag后再改be。 本学案使用中性清理记录，不把不同地区的垃圾分类颜色作为语法题的判分依据。可结合学校已有分类标识进行口头拓展。 第 页 学科网（北京）股份有限公司 $
