THE FIGHT AGAINST GLOBAL WARMING
Carbon dioxide (CO2) is a greenhouse gas that occurs naturally in the atmosphere. Human activities, such as burning fuel in power plants or vehicles, are increasing the amount of CO2 in the atmosphere. This is contributing to Earth's global warming. Scientists are developing ways to capture the CO₂ released from power plants and factories and store it underground. This technique is called carbon dioxide capture and storage (CCS).

So, how does CCS work? Carbon dioxide from a power plant or factory is trapped, so it is not released back into the atmosphere. A pipeline sends this trapped CO₂ to a place underground, where it can be stored safely and permanently in rock formations. This area is checked regularly to make sure the stored CO₂ doesn't leak.

While most of the carbon dioxide will be stored, some of it will be reused successfully. We can reuse the carbon to make things like house-building materials, and to treat waste water. In 2015, a French company, Air Liquide, announced that it will build a carbon-capture power plant that will capture up to 50,000 tons of carbon dioxide a year. The company will use the carbon dioxide to carbonate drinks and treat waste water.

Carbon-capture technology is still developing, and it will be quite a few years before it can be used commercially and on a large scale. However, in the long run, this technology may help decrease CO₂ and at the same time make money for the carbon-capture companies. This can only be good news in the fight to stop global warming.

3. Lời giải chi tiết

1. CO2 is increasing in the atmosphere because of  _____

Answer: b. burning fossil fuel

Explanation: The article states that human activities, such as burning fuel in power plants or vehicles, are increasing the amount of CO2 in the atmosphere.

2. The word "capture" means _______

Answer: a. get

Explanation: "Capture" in this context means to trap or collect something, in this case, CO₂ from power plants and factories.

3. With the help of CCS, most of the CO₂ from a power plant or factory will be

Answer: a. stored underground

Explanation: The article mentions that CO₂ captured from power plants and factories will be stored safely and permanently underground in rock formations.

4. Scientists are probably more concerned about the safety of ________.

Answer: c. storing CO₂

Explanation: Since the article emphasizes the need for CO₂ storage to be safe and to prevent leaks, it suggests that scientists are likely more concerned about the safety of storing CO₂.

5. The writer thinks that carbon-capture technology will.

Answer: c. help to stop global warming in the long run

Explanation: The article concludes by stating that carbon-capture technology, although still developing, may help decrease CO₂ and make money for carbon-capture companies, suggesting a positive outlook for its role in fighting global warming in the long run.
