Mr Quang: Good morning, class. Today’s lesson will start with Mai and Nam’s talk about some of the causes and consequences of global warming. Would you like to go first, Mai?

Mai: Yes, thank you. First, let me remind you what global warming refers to - it’s the increase in the earth's temperature because of certain gases in the atmosphere.

Nam: Exactly. These gases are mainly produced through human activities. For example, burnt for energy, fossil fuels release large amounts of carbon dioxide into the atmosphere.

Mr Quang: But how do these gases make the earth warmer?

Mai: Well, they act like the glass in a greenhouse. Trapping too much of the sun’s heat, they stop it from escaping back into space. This makes the planet hotter and hotter.

Nam: That's right. That’s why these heat-trapping pollutants are known as greenhouse gases, and their impact is called the greenhouse effect.

Mai: Global warming is also linked to rising sea levels. As temperatures rise, polar ice caps melt faster, adding more water to oceans. Higher sea levels can also lead to floods.

Nam: Each year, the consequences of global warming become more serious, and its negative impact on the environment and people gets stronger.

Mr Quang: Good job! Thank you for sharing the information.

Read the essay. What is the writer's opinion about the problem? How many solutions does she propose?

Most people agree that the lack of exercise in teenagers' lives is a serious problem. But what are the causes of this problem and what can we do to address them?

I strongly believe that today's teenagers spend too much time playing on electronic gadgets. They hardly ever do outdoor activities and this is why many of them do not get enough exercise. What is more, many teenagers are overweight and this makes them less willing to do exercise.

In order to tackle this problem, a number of measures are necessary. In my view, it is unrealistic to limit the amount of time teenagers spend on gadgets. What I propose instead is that we make sure school canteens only serve healthy food. Furthermore, I would strongly recommend that we give all teenagers free membership of their local sports facilities.

To conclude, lack of exercise can cause long-term health problems, so it is vital that we act now. It seems to me that the measures I propose will begin to remedy the situation.
