Pick out all there be sentences in the dialogue and divide them into there is / there are. There is more and more plastic pollution… There are many things we can do. there are always many bottles and plastic bags… Are there any other things… 2. Change the sentence “Many plastic bags are on the beach” into there be structure. There are many plastic bags on the beach. 基础浅层任务 1：垃圾分类造句示例 · Recyclable waste（blue）：There is a lot of paper. There are some plastic bottles, tin cans, broken glass and clothes. · Residual waste（black）：There are some plastic bags. · Food waste（green）：There are many fish bones. · Hazardous waste（red）：There are some lithium batteries. 进阶理解问题链（语法规则梳理） 1. What’s the difference between countable plural & uncountable nouns for there be? Uncountable / single noun → there is; plural countable → there are. 2. What is the proximity rule（就近原则）? When we list two kinds of things, the form of be follows the first noun. 3. What environmental problems does the dialogue talk about? Plastic rubbish, bottles and plastic bags pollute the sea and hurt sea animals. 深度逻辑问题 Why do we use there be to talk about rubbish on the beach? There be is used to describe things existing in a place, perfect for describing waste on the beach. （二）合作探究・小组活动突破（4 人互助小组） 活动 1：单复数名词分类造句竞赛 小组区分可数复数、不可数名词，分别造 there is /there are 环保主题句子。 活动 2：句型转换小游戏 给出普通陈述句，组员轮流改写为 there be 肯定、否定、疑问句。 活动 3：双人演讲稿准备（Grammar in use 任务 2） 对话模板： S1: Let’s prepare the speech for Beach Clean-up Day.
