Ⅳ.任务型阅读
阅读下面短文,按要求完成26~30题。
Protecting our environment is very important. “When it comes to the earth, there is no time to waste,” says the Earth Day Network. And that is right. World Earth Day was created in 1970 to ask more people to protect our environment. On April 22, people around the world celebrate Earth Day.
Every year there is a special topic, and in 2016 it was “Trees for the Earth”, so Earth Day that year was all about planting trees. They planned to plant 7.8 billion trees within the next five years.
That’s a big goal, and you might wonder why trees are so important. Because they can take in carbon dioxide (CO2) and protect the air quality(质量). CO2 is a chemical in our atmosphere, but humans make too much of it. Each person makes about 2.3 tons a year, which is bad for the environment.
Well, guess what! Planting new trees is important because people cut down a large number of trees. Last year, there were 3 trillion trees in the world, about 139 billion in China. But according to China Daily, the world’s total number has been almost cut in half since human civilization(文明) began. That’s because 15 billion trees are cut down every year.
So we need to plant more to make up for(弥补)the ones we lost. One tree can take in 21.8 kilograms of CO2 per year. And it’s still one of the cheapest and best ways to get rid of CO2.
But don’t forget that we can also help the environment by cutting down how much energy(能源) or water we use every day. Every little thing helps.
