“Plant-for-the-Planet” came out of a school project when Finkbeiner was a fourth-grader. 61 topic was climate change.

Instead of information about polar bears, he found stories 63 Wangari Maathai. The Kenyan woman had planted 30 million trees in order to fix the environment of her hometown. The effort won her the Nobel Peace Prize in 2004. Finkbeiner realized 64 it was not really about saving polar bears. Instead, it was about saving humans. He made a big decision: to plant one million trees in Germany. He talked about it with all his 65 (classmate) and his head teacher. No one expected anything to come of it, but the boy was serious about his goal. Two months later, Finkbemer planted his first tree.

Our planet is a great place, but it needs our help to thrive! That’s 88 each year on April 22, more than a billion people celebrate Earth Day and protect the planet from things like 89 (pollute) and deforestation (砍伐森林). By taking part in some environmental protection activities, we can make our world a happier and healthier place to live.
The first Earth Day was 90 (celebrate) in 1970, when a United States senator(参议员) from Wisconsin organized a national demonstration to 91 (raise) awareness about environmental issues. By 1990 Earth Day had become 92 event celebrated by more than 1400 countries around the globe.
We can celebrate and protect the planet at the same time. Here is an Earth Day idea—becoming a waste warrior(勇士). Garbage that Americans throw away every day can fill 93 (rough) 6300 garbage trucks, which if lined up end to end for an entire year would stretch halfway 94 the moon. Toilet paper tubes, 95 (make) from cardboard, take two months to break down in a landfill. But instead of turning to the trash bin, you could turn these items into an 96 (amaze) telescope or a nice flower planter. Before 97 (throw) something away, you can think about whether it can be recycled or not.
Where does our rubbish go Every day workers come to take the rubbish from our rubbish bins. Then it 98 (put) into a big truck and carried to landfills (垃圾填埋场) where it is sorted (分类) and recycled. We all know the more rubbish gets recycled, the better it is for our environment. We should put the rubbish in the right bins. In this way, we 99 (help) save a lot of time, money and energy for all the society.
100 people in Beijing sort out their rubbish, they will get the WeChat bonus points (积分) to exchange for shopping cards or other things.
Many countries have good sorting systems. In Sweden, only 4 percent of household waste 101 (end) up in landfills every year. In China, people make about 300 million tons of rubbish every year. I think we will have a better environment as long as everybody recycles the rubbish every day.

There are many ways to save the environment if you would like. In this passage, you can find some ways.
Plant more trees. Choose a right ground near your house or workplace. 102 there’s any rule stopping you from 103 (grow) trees in that area, go ahead and grow trees. Plant a tree every month and 104 (encourage) your friends and classmates to join you. Have more and more trees 105 (plant) and there will come a day when you have green land thanks 106 your hard work.
Walk more and drive less. Choose to walk rather than drive your car. Walk or ride a bicycle to work if it’s not very far. Not only cycling but walking is good 107 (exercise). And each time you avoid using your car, you’re doing something 108 (help) to cut down air pollution. You are saving fuel (燃料), saving money and keeping fit as well.
Save water. Water is very important for 109 (live) things. It’s we who use and pollute 110 (it). The simplest way to save water is turning off water taps after use. When you visit a beach, make sure that you don’t throw waste around. Do not pollute rivers 111 dropping rubbish or other waste. Water is so valuable, so we can’t waste or pollute it.
When throwing away rubbish, do you know 112 bin it should go in Have you ever 113 (notice) the differently-colored rubbish bins on the street
Some of you might not be able to answer the questions. However, it’s actually quite 114 (importance) to know how to sort(分类) your rubbish. Not 115 (know) how to sort rubbish can make it 116 (hard) to save energy and protect the environment. If you don’t sort your rubbish, 117 of it will be buried(埋) together. It can take up large areas of ground that could have been used for 118 (plant) trees. Shanghai is the first city 119 (put) rubbish-sorting into practice in China. Shanghai government has asked all the people who live there to sort rubbish into four groups: wet, recyclable, harmful and dry. “Wet” rubbish is also known as “household” rubbish. It is what people produce every day 120 they eat or drink. “It is the thing you don’t want but pigs can eat”, Guangzhou Daily explained. Paper, metal, glass and other things that can be recused are recyclable rubbish. Harmful rubbish includes things like medicine, batteries and so on. Finally, any rubbish that is not wet, 121 (recycle) or harmful will go in the dry rubbish bin.

Our planet is a great place, but it needs our help to thrive! That’s 88 each year on April 22, more than a billion people celebrate Earth Day and protect the planet from things like 89 (pollute) and deforestation (砍伐森林). By taking part in some environmental protection activities, we can make our world a happier and healthier place to live.
The first Earth Day was 90 (celebrate) in 1970, when a United States senator(参议员) from Wisconsin organized a national demonstration to 91 (raise) awareness about environmental issues. By 1990 Earth Day had become 92 event celebrated by more than 1400 countries around the globe.
We can celebrate and protect the planet at the same time. Here is an Earth Day idea—becoming a waste warrior(勇士). Garbage that Americans throw away every day can fill 93 (rough) 6300 garbage trucks, which if lined up end to end for an entire year would stretch halfway 94 the moon. Toilet paper tubes, 95 (make) from cardboard, take two months to break down in a landfill. But instead of turning to the trash bin, you could turn these items into an 96 (amaze) telescope or a nice flower planter. Before 97 (throw) something away, you can think about whether it can be recycled or not.
Where does our rubbish go Every day workers come to take the rubbish from our rubbish bins. Then it 98 (put) into a big truck and carried to landfills (垃圾填埋场) where it is sorted (分类) and recycled. We all know the more rubbish gets recycled, the better it is for our environment. We should put the rubbish in the right bins. In this way, we 99 (help) save a lot of time, money and energy for all the society.
100 people in Beijing sort out their rubbish, they will get the WeChat bonus points (积分) to exchange for shopping cards or other things.
Many countries have good sorting systems. In Sweden, only 4 percent of household waste 101 (end) up in landfills every year. In China, people make about 300 million tons of rubbish every year. I think we will have a better environment as long as everybody recycles the rubbish every day.

It can take up large areas of ground that could have been used for 118 (plant) trees. Shanghai is the first city 119 (put) rubbish-sorting into practice in China. Shanghai government has asked all the people who live there to sort rubbish into four groups: wet, recyclable, harmful and dry. “Wet” rubbish is also known as “household” rubbish. It is what people produce every day 120 they eat or drink. “It is the thing you don’t want but pigs can eat”, Guangzhou Daily explained.

Reduce means “use less”. Do not waste things. Do not order more food 146 you can finish. Turn off the lights when you do not need them. Before you buy something new, think 147 it is really necessary or not because maybe the old one is just as good!

Recycle means “change things into something else”. Although it takes energy, it is better than throwing them away. We 150 (throw) tons of rubbish away in our daily life so far, and we have to make a change from now on. Develop a recycling policy for the whole. Buy products such as recycle paper to help save trees.
We cannot hope for 151 rapid change, but let’s take the simple steps today for our future.
There are some easy things you can do to protect the 152 [ n’va r nm nt] and the earth. Choose ideas from the list or come up with(提出) a few of your own.
·Plant flowers, 153 (grass) or trees.
·Whenever you visit a park, take away what you bring there—keep 154 [‘r b ] in a bag until you can put it in a dustbin.
·Turn 155 the lights and TV sets when you leave the room. This can save a lot of electricity.
·Give your old books and magazines to a library instead of 156 (throw) them away.
·Don’t throw your old clothes away, and give them to poor children you know.
·Use 157 sides of paper.
·Stop 158 (pour) dirty water into the rivers or lakes nearby.
· 159 [ n’k r d ] all your friends to do the same things you do to help protect the earth.
You don’t have to wait until Earth Day to do these things. Make every day Earth Day. If everyone makes a 160 to protecting the environment, the world will become 161 more beautiful.
