Save the world's trees

    "When it comes tothe Earth, there is no time to waste." says the Earth Day Network. And that isright. Protecting our environment is very important, and World Earth Day wascreated in 1970 to ask more people to protect our environment. On April 22, peoplearound the world celebrate Earth Day.

Every year thereis a special topic, and this year it is "Trees for the Earth", so Earth Daythis year will be all about planting trees. They are planning to plant 7.8billion trees within the next five years.

That's a biggoal, and you might wonder why trees are so important. Because they can take incarbon dioxide (CO₂) and protect the air quality(质量). CO₂ isa chemical in our atmosphere, but humans make too much of it. Each person makesabout 2.3 tons a year, which is bad for the environment.

Well guess what!Planting new trees is important because people cut down a huge number of trees.Last year, there were 3 trillion trees in the world, about 139 billion inChina. But according to China Daily, the world's total number has been almostcut in half since human civilization(文明) began. That's because 15billion trees are cut down every year.

So we need toplant more to make up for（弥补）the ones we lost. One treecan take in 21. 8 kilograms of CO₂ per year. And it's still one ofthe cheapest and best ways to get rid of CO₂.

    But don't forget that we can also help the environment by cutting down on how much energy(能源) or water we useevery day. Every little thing helps.

根据材料内容简要回答下列问题。

    We have always been interested in the Moon. 2,000 years ago, people already knew it moves around the Earth and where it would be in the sky at different times of the year. {#blank#}1{#/blank#}

    When scientists could use telescopes to study the Moon more closely, their ideas began to change. They could see the Moon was made of rocks. {#blank#}2{#/blank#} And they believed the Moon had once been a planet. It was caught in Earth's gravity millions of years ago.

    In 1969, Moon rocks were finally brought to the Earth by astronauts. {#blank#}3{#/blank#} To their surprise, scientists found that the Moon and the Earth are made of the same things except for water. {#blank#}4{#/blank#}

    After years of study, some scientists think that the Moon was once part of the Earth. They believe maybe 4 million years ago, something hit the Earth. {#blank#}5{#/blank#}These rocks slowly joined together and after many years became the Moon.

    In the future, even though our ideas about the Moon may change again, we will still be interested in it.

    Chogori(乔戈里峰)stands on the Chinese-Pakistan border. Chogori is from the Tajik language, it means" high, great and magnificent". Internationally, it is better known as K2. Chogori is about 8, 611 meters high, and it is the second highest mountain in the world.

    And Chogori is not Qomolangma. On the one hand, Chogori is a steeper(更陡峭的)and more dangerous peak. In fact, it is the most difficult peak to reach in the world. The first two people to reach the top of Chogori—Lino Lacedelli and Achille Compagnoni from Italy—did it in 1954. In 1986, the first woman did it too. Since 1954, only 281 people have reached the top, and 49 others have been killed (However, Qomolangma has been reached 3, 000 times and only 15 climbers lost their lives). Of all the over 8, 000-meter-high peaks, it has the highest death rate.

    On the other hand, this great peak is for professional climbers only. Here, no commercial(商业的)climbing organization will provide you any services, and even top-class climbers will choose their climbing partners with a particularly eagle(鹰)eye. The leader of a Japanese K2 team said when organizing his team in 1982, "We are professional climbers, and all know that if we run into trouble at a height of 8, 000 meters on K2, it is impossible to get help. If you do not have the confidence and determination(决心)to face possible trouble, you should not go!"

    This is Chogori! In the eyes of the top-class climbers, it is the most beautiful peak, and it is the danger that attracts them.
