更换前修理
When an object breaks, replacing it is one option, but it is not always the first useful step. A loose screw in a wooden model or a torn seam in a cloth bag may be repairable. Checking the damage can prevent a useful object from being discarded unnecessarily.
Repair also has limits. An object with a sharp broken edge or damaged electrical parts may be unsafe to handle. Some repairs require particular tools, skills or adult help. The time and supplies needed may also exceed what is available. A decision should consider those conditions rather than treating repair as a rule that applies to everything.
A class repair box can support small, suitable jobs by keeping tape, thread and spare labels together. It cannot make every damaged object safe. Before choosing repair or replacement, describe the damage, check what help is needed and decide whether the result can be used safely.
示例：“The schedule lists two departures”报告依据；“Two departures offer two possible travel times”解释其作用。说明文应把细节与问题相连，而非只列出细节。 根据材料完成各项任务，按要求作答。
1.根据这篇文章写说明文，可以回答什么问题？ What question could an explanation based on this text answer?
2.从不同段落选择两项有助于回答该问题的细节。 Choose two details from different paragraphs that would help answer that question.
3.规划引言、解释好处的段落、解释限制的段落和结论。 Plan an introduction, a paragraph explaining the benefit, a paragraph explaining a limit and a conclusion.
4.转述一个选定细节，再用第二句话解释其重要性，保留限定条件。 Paraphrase a selected detail, then explain its importance in a second sentence. Keep any qualification.
5.用 however 从好处过渡到限制，解释两者的关系。 Write a transition from a benefit to a limitation using however. Explain the relationship.
6.写2至3段说明文回答问题，使用两项原文细节、解释其作用，并以有限定的结论结束。 Write a 2–3 paragraph explanation answering your question. Use two source details, explain their relevance and end with a qualified conclusion.
7.修改说明文中的一句话，使证据与解释联系更清楚，给出修改前后版本。 Revise one sentence in your explanation to connect evidence and reasoning more clearly. Give before and after versions.
8.指出一个原文观点和一个自己的建议，解释如何区分。 Mark one idea from the source and one suggestion of your own. Explain how you made the distinction clear.

示例：“The schedule lists two departures”报告依据；“Two departures offer two possible travel times”解释其作用。说明文应把细节与问题相连，而非只列出细节。 根据材料完成各项任务，按要求作答。
1.根据这篇文章写说明文，可以回答什么问题？ What question could an explanation based on this text answer?
- 保留材料中的事实、顺序和限定条件。
- 接受意思相同的表述及有材料依据的其他解读。
一种参考回答： How can someone consider repair while checking condition, resources and safety?
2.从不同段落选择两项有助于回答该问题的细节。 Choose two details from different paragraphs that would help answer that question.
- 使用材料中的相关细节，并解释它们之间的联系。
- 回答所有要求的部分；接受有充分依据的其他答案。
一种参考回答： The example about a torn seam in a cloth bag may be repairable and the checking method in the final paragraph connect the benefit with the conditions.
3.规划引言、解释好处的段落、解释限制的段落和结论。 Plan an introduction, a paragraph explaining the benefit, a paragraph explaining a limit and a conclusion.
- 回答所有要求的部分；接受有充分依据的其他答案。
- 保留材料中的事实、顺序和限定条件。
一种参考回答： Introduction: consider repair while checking condition, resources and safety. Benefit: explain a first-paragraph example. Limit: explain a torn seam in a cloth bag may be repairable. Conclusion: use the final checking method.
4.转述一个选定细节，再用第二句话解释其重要性，保留限定条件。 Paraphrase a selected detail, then explain its importance in a second sentence. Keep any qualification.
- 保留材料中的事实、顺序和限定条件。
- 使用材料中的相关细节，并解释它们之间的联系。
一种参考回答： A torn seam in a cloth bag may be repairable. This detail shows why a useful method still needs a careful check.
5.用 however 从好处过渡到限制，解释两者的关系。 Write a transition from a benefit to a limitation using however. Explain the relationship.
- 使用指定的英语表达，且意思符合情境。
- 结论限定在材料所描述的人群、结果和条件范围内。
一种参考回答： This approach can be useful in suitable circumstances. However, its benefit does not remove the need to check the conditions.
6.写2至3段说明文回答问题，使用两项原文细节、解释其作用，并以有限定的结论结束。 Write a 2–3 paragraph explanation answering your question. Use two source details, explain their relevance and end with a qualified conclusion.
- 使用材料中的相关细节，并解释它们之间的联系。
- 结论限定在材料所描述的人群、结果和条件范围内。
- 写出连贯的完整句子，正确使用大写字母和标点。
- 回答所有要求的部分；接受有充分依据的其他答案。
一种参考回答： The text recommends that readers consider repair while checking condition, resources and safety. Its first examples explain a practical benefit, while later paragraphs show why the approach needs limits. For example, a torn seam in a cloth bag may be repairable. This illustrates a condition that should remain in any explanation of the advice. A sharp broken toy edge needs an adult safety check; replacement may be appropriate. The approach is useful when its conditions are checked. A careful decision preserves both the possible benefit and the relevant limitation.
7.修改说明文中的一句话，使证据与解释联系更清楚，给出修改前后版本。 Revise one sentence in your explanation to connect evidence and reasoning more clearly. Give before and after versions.
- 指出具体修改，并说明它如何改善意思或清晰度。
- 使用材料中的相关细节，并解释它们之间的联系。
一种参考回答： Before: “The method is useful.” After: “The example about a torn seam in a cloth bag may be repairable shows why the method needs a check before it is used.”
8.指出一个原文观点和一个自己的建议，解释如何区分。 Mark one idea from the source and one suggestion of your own. Explain how you made the distinction clear.
- 回答所有要求的部分；接受有充分依据的其他答案。
- 保留材料中的事实、顺序和限定条件。
一种参考回答： “a torn seam in a cloth bag may be repairable” comes from the text. I introduced my new situation as an example of my own rather than a reported event.
