Bài giảng

A new conversation

Mai: What are you preparing for our class discussion about science and technology?
Nam: I have a short report. Here is my main idea.

Our group designed a simple reminder device for the classroom. A light appears after a set period so students remember to take a short break. We tested whether the timer was accurate and asked users whether the light was distracting. One student said that the signal was too bright,so we changed it. We do not claim that the device solves every study problem. A useful invention should answer a real need,be tested fairly,and explain its limits. Safety and privacy matter as much as a clever idea.

Mai: Can you give a reason for your opinion?
Nam: Yes. We should consider both benefits and difficulties.

Reading the situation

Identify who is speaking,the topic,and why the follow-up question matters. Underline the words that support an opinion. Then replace the sample experience with your own truthful example.
