Listen for a detail
Which issue remains unresolved in the recording?
Show script, meaning, and explanation
这个办法成本已经下降，但效果仍然需要更多试验来确认。便宜并不等于一定有效。
Its cost has fallen, but effectiveness still needs trials. Being cheaper does not guarantee effectiveness.
效果仍然需要更多试验 says effectiveness still needs evidence.
If you use the script, this becomes supported reading. Close the script and replay the recording when you are ready.
Read a different account
这项节水办法在小范围试验中取得了效果，但设备成本较高，因此暂时没有全面推广。负责人认为，今后成本下降时，可以再次评估。试验结果值得关注，却不足以证明它适合所有地区。
Show English meaning
A water-saving method worked in a small trial, but high equipment costs prevent full rollout for now. It can be reassessed if costs fall. The trial is promising but does not prove suitability everywhere.
Which claim is supported by the reading?
Show the answer and why
It worked in a limited trial — 小范围试验中的效果 is limited evidence; the final sentence rejects universal certainty.
Speak with a new detail
Explain the method’s promise and limitation to a partner. They ask whether the trial proves universal success.
Try without reading. Work with a partner or make a private recording and listen back. Check the message and the response to your partner; pronunciation needs actual speech.
Show one model
小范围试验有效，但成本较高，暂时没有全面推广。不能说适合所有地区。
Write and revise
Write a cautious recommendation based only on the reading.
Show a model and self-review checklist
试验结果值得关注，但样本范围有限，设备成本也较高。可以在成本下降后继续评估，不宜直接推广到所有地区。
- Separate evidence from recommendation.
- Preserve the limited trial scope.
- Keep 暂时 distinct from 永远.
Your writing is not uploaded or automatically graded. Several responses may fit the task.
Remember for next time
A barrier today does not establish permanent impossibility. Conversely, removing the cost barrier does not by itself prove effectiveness.
Tomorrow, recall two words and try the speaking task with a new detail. A few days later, revisit the listening without its script.
Teacher and partner guidance
Model the goal, then let the learner attempt it. Check understanding of the spoken passage with the script hidden. Use the writing checklist to discuss meaning and structure; use actual speech to observe intelligibility and interaction. These public tasks are formative and must not be reused as unseen tests.
