進階區分 linear vs circular economy完成
依 Reading 1,用一句話分別說明 linear economy 與 circular economy 的運作,並各舉一個關鍵差異。
提示
linear=take-make-use-throw away;circular=繞圈、消除 waste、用更久。
解答(逐步)
Linear economy:take raw materials → make → use → throw away(直線、最終丟棄,不可持續)。
Circular economy:Raw materials → design & make → use → reuse & repair → recycle → 回到 raw materials(繞圈、以消除 waste 為核心,讓資源使用更久)。
關鍵差異:linear 把約 two-thirds 原料變成 waste;circular 透過設計、翻新、提取零件、廢料再利用減少對新原料的需求。
進階辨識 essay 結構元素完成
讀下列引言段,找出 ① hook ② thesis statement,並指出 thesis 的 topic 與 claim: "Our planet is like a living, breathing body. The take-make-throw-away model is making our planet sick. If we move to a circular economy, both inputs and outputs will be better balanced, so our planet will stay healthy."
提示
hook 通常是引人入勝的第一句;thesis 在段末,含主題+主張。
解答(逐步)
① hook:「Our planet is like a living, breathing body.」(用比喻抓注意力)。
② thesis statement:「If we move to a circular economy, both inputs and outputs will be better balanced, so our planet will stay healthy.」
   - topic(主題)=循環經濟對地球(環境)的影響。
   - claim(主張)=轉向循環經濟能讓地球維持健康(即循環經濟有益環境)。
挑戰被動語態改寫(省略 agent)完成
把下列句子改成被動語態,且不要包含 agent: (1) They will not release the results until next year. (2) Scientists say we must repeat these studies every few years. (3) The research center is extending the deadline for applications.
提示
受詞當主詞;注意時態:未來 will be + p.p.;情態 must be + p.p.;進行式 is being + p.p.。
解答(逐步)
(1) The results will not be released until next year.
(2) These studies must be repeated every few years.
(3) The deadline for applications is being extended.
挑戰改善 cohesion(用被動重寫含 people 的句子)完成
改善下段銜接:把含「people」的句子改成被動(去掉 people 這個不重要的 agent)。 "Product packaging costs a lot, but people recycle very little of it. When a bottle of soap is finished, people can return it to a vending machine. Each time people return it, the price of the soap is lower."
提示
people 是泛指、不重要的 agent,改被動後句子更客觀、銜接更順。
解答(逐步)
Product packaging costs a lot, but very little of it is recycled. When a bottle of soap is finished, it can be returned to a vending machine. Each time it is returned, the price of the soap is lower.
(三處 people 的主動句都改成被動、省略 agent,主詞改用前句提到的事物,cohesion 更佳。)
