Listening Test Summary

Dialogue 1: Global Warming

• Participants: Student 1 (Unknown), Carla
• Topic: Discussing global warming and its effects

Key Points:

• Current Weather: Too hot due to global warming.
• Global Warming: Has a significant impact on natural conditions for both animals and humans.
• Process of Global Warming:
  • Sunlight shines on the earth.
  • Earth absorbs heat; half is reflected back to the atmosphere.
  • Gases in the atmosphere (CO2, SO2, methane, water vapor) trap heat - known as the greenhouse effect.
• Ozone Layer: Thinning due to solar radiation increase, contributing to higher temperatures.
• Consequences: Earth continuously gets hotter.
• Solutions to Decrease Global Warming:
  • Using public transportation instead of personal vehicles reduces carbon dioxide emissions.

Questions from Dialogue 1:

1. What are they talking about?
   • Global warming and its effects.
2. What will happen if the sunlight shines on the earth?
   • Heat is absorbed and reflected back, contributing to the greenhouse effect.
3. What is greenhouse effect?
   • Trapping of heat by gases in the atmosphere, leading to increased temperatures.
4. Effects of solar radiation on the earth's atmosphere?
   • Thinning of the ozone layer and increased earth temperatures.
5. Solution to decrease global warming?
   • Use public transportation.

Dialogue 2: Flooding

• Participants: Unknown, Carla
• Topic: Discussion on flooding in the capital city

Key Points:

• Current Events: Flood in the capital city trapping people in homes.
• Natural Flooding Process:
  • Rain falls and is absorbed by the ground.
  • Excess water causes evaporation and surface water increase.
• Disastrous Impact: Flooding can carry away houses, bridges, cars, furniture, and people.
• Non-Natural Flooding:
  • Caused by human habits (e.g., littering leading to clogged water flow).
  • Poor environmental practices can result in overflowing water reservoirs.
• Prevention:
  • Change habits (e.g., avoid littering).
  • Planting trees to enhance rainwater absorption and prevent flooding.

Questions from Dialogue 2:

6. What are they talking about?
   • Flooding in the capital city.
7. Where does flooding usually happen?
   • In large, densely populated cities.
8. How is the process of natural flooding?
   • Begins with rain absorption, leading to water overflow.
9. What can cause non-natural flooding?
   • Human activities such as littering and poor waste management.
10. How to prevent flooding?

• Improve environmental practices and plant more trees.
