How the greenhouse effect works
Gases like (1) carbon dioxide are important for the Earth's temperature. They let heat from the Sun reach the ground, and keep it there. In this way, they help to keep the Earth's temperature at the ideal level. However, human activities are destroying the natural (2)............of these gases. When we burn fossil fuels like (3).............oil and gas, we produce too much carbon dioxide (CO2). This CO2 collects in the atmosphere and (4)............too much heat. We make the problem worse when we cut down (5).............Living trees absorb carbon dioxide and (6)............ oxygen, but when we cut trees down we release carbon dioxide back into the atmosphere.
Exercise 16. Replace the words in italics with a phrasal verb from the box in the correct form. There are two verbs that you won't need.
 |
1. Our planet is in great danger. We all need to accept and deal with the challenges if we are to avoid disaster.
2. We will probably no longer have enough oil in the next 60 years, so we need to develop renewable energy sources such as wind power.
3. Natural resources like wood and coal are being finished at an ever-increasing rate.
4. We ought to reduce the amount of energy we use; for example,
we should switch off lights when we leave a room.
5. We ought to stop using cars for unnecessary journeys and use public transport instead.
Exercise 17. Underline the correct word in each pair. Then answer the questions with a partner.

2. According to the text, what will happen if we don't do something about it now?
Exercise 19. Now complete the exam task. Read the gapped sentences very carefully. Remember, to help you choose the right word, you should:
• pay careful attention to meaning.

GLOBAL WARMING
The Earth's climate is a very complicated system. What's more, it is now widely (0) .A. that human activity is having an effect on it. The pollution which (1).....from the use of oil and coal in industry, (2).....the increased use of private cars, is causing significant changes in temperature in many parts of the world. These changes often have a knock-on effect on other aspects of the climate, (3).....to things like extreme weather (4).....and rising sea levels.
Studying the changes which are taking (5).....and predicting those that are (6).....to happen in the future is now a major area of scientific research. The information which the scientists (7).....is very useful in helping governments to (8).....the effects of climate change and so be better prepared to (9).....with them. A much more (10).....problem, however, is how to prevent the situation from (11).....worse. This depends on how quickly, and to what extent, the (12).....of pollution in the atmosphere increases. Although many countries have now agreed to try and limit the pollution they create, much more (13).....to be done. If no further action is (14)......then temperatures are set to rise by about 0.2% per decade (15).....the 21st century. Such a rate of warming is greater than anything that has occurred over the last ten thousand years.
