First question: how many big oceans are there on Earth? Mia: Five. Host: Correct. Now, why are sea levels rising? Leo: Ice on land is melting. The water enters the sea. Host: Right. Warmer sea water also takes up more space. Both make sea levels rise. Next question: why is plastic pollution dangerous? Mia: Fish and other sea animals may eat plastic. They may also get trapped in it. They can get ill or die. Host: Yes. Now think about fishing. What happens if people catch fish faster than fish can grow and reproduce? Leo: There will be fewer fish. That is overfishing. Host: Good. Last question: what can students do? Mia: We can bring a reusable bottle instead of buying a new plastic bottle each time. Leo: And we can pick up rubbish on the beach before it reaches the sea. Host: Exactly. Small actions can help when we keep doing them. 听前词语提示 必要时口头解释：melt 融化；trapped 被困住；reproduce 繁殖；reusable 可重复使用的。不提前透露选择题答案。 发音示范句 Rubbish can harm sea animals. There is a plant near the bag. The bottle is full. We need clean air and safe food. 教材第59页列出八个目标音，本课先准确模仿，再把重音放到信息词上。英式读音中 hot 为/ɒ/，plant 为/ɑː/；不把可接受的口音差异判作知识错误。 参考答案与口语评价 听力答案 听前匹配：1 C；2 D；3 A；4 B。预测不计对错，应与听后结果比较。 1. B。2. 勾选 rising sea levels、plastic pollution、overfishing；不选 coral reefs disappearing。未提到并不等于现实中不存在。 表格：(a) land；(b) trapped；(c) grow；(d) bottle；(e) beach。 3. 示例：The quiz asks us to bring a reusable bottle and pick up rubbish on the beach. 也可答 We should not catch fish faster than they can grow and reproduce。关键是纠正catch more fish。4. Five / 5。 资料卡与问答示例 A: People catch too many fish, so there are fewer fish in the sea. B: People use dangerous farm chemicals, so there is less clean groundwater.
