Chimney, fossil fuels, smog, haze, greenhouse effect, and new energy vehicles. 2. What information can you get from these pictures? I can get information about where the pictures were taken, for example, the bridge is in London, and the chimneys are in a power station. Both places look very polluted. I can see that the car is powered by electricity as it is plugged in. I can see some coal being burned. These pictures tell me that the interview is probably about energy and pollution. 3. How do these situations influence your life? These situations influence my life not only by providing electricity for me, and transporting me, but also by polluting the air I breathe. 4.

Learn about how to summarize information while listening. Summarizing information: In active listening, summarizing helps you review the key points of a speaker’s message. In order to write a good summary, you must take notes of the most important points as you listen. When summarizing, you need to be as concise as possible and use your own words. 3. Scan the text. Listen again and take notes on what the expert said. Then summarize the information you got from the interview. Suggested answers: in the early 20th, industry, used lots of coal, was particularly bad and caused over 4,000 deaths, burning coal, move away from city centers, replace coal with cleaner forms of energy, new energy-efficient vehicles, green technology. 4.

These measures include restricting the consumption of coal, developing clean energy, controlling the emission of pollutants (控制污染物排放), enforcing new emission standards (执行新的排放标准) and using public transport. 2.
