When the Spring Festival falls, red flowers bloom(盛开) on the windows of my home. Of course, these are not1flowers. But in the cold of2, these wonderful flowers bring warmth to us. They are made of paper by my3, who is now aged 70, with a few cuts, she   4a piece of paper into a beautiful work of art.

    When my grandma was considered clumsy(笨拙的) in the 5. But on a cold winter night, she saw some beautiful red paper6 on her new neighbor's windows. She was so interested in it and decided to 7from her neighbor. Tons of paper was wasted, and her fingers were cut many times. But she8practicing. It took 10 years9my grandma could make paper art skillfully(娴熟地). The red flowers, blooming like hurning fire, light up her world. Now, everyone in the village10her.

    My grandma's story has shown me what it takes to realize one's dream.

    Each one of us shares this planet with over seven billion others. And we all need1. People and products need to move from city to city and country to country. However, we all know2most cars, motorcycles, boats and planes cause air pollution. They are also3. This is a serious problem in many cities.4inventors are coming up with creative ideas to try to reduce the pollution and noise.

    In many cities around the world, motorcycles are very5. Now Vietnam has around 33 million motorcycles and China has almost 120 million. Motorcycles are a faster and cheaper way to get around a city than6. Yet air pollution is a growing problem. In large cities, people7it is difficult to breathe. To solve these problems, an American company designed an environmentally friendly motorcycle. It uses electricity as fuel (燃料). As a result, there is8pollution. It's also quiet and fast. This makes9a good choice for getting around a city.

    The Italian city of Venice is a city with only a few10. There are no cars in the city centre.11cars, water taxis and buses carry people along the city's canals (运河). However, they cause pollution,12to the water. English engineers Dick and Jem designed a solar-powered (太阳能的) water taxi. The water taxi13run for a day after being charged (充电).

    Planes also cause air and noise pollution. Designing an environmentally friendly airplane is a real14. Some airplane companies have15to solve the problems. Swiss engineers have gone one step further. They developed a solar airplane. This airplane even tries to travel around the world.

Florence Nightingale was born on May 12th, 1820. In 1851, she trained as a nurse. Two years later she went to a British military (军事的) hospital so that she could help British soldiers. Before she arrived, many soldiers died in the hospital because it was dirty. Nightingale worked hard to make the hospital clean and stop soldiers dying. When she returned to England in 1856, she was a national heroine. Nightingale wrote two books about nursing and she also started a school to train nurses. She died in London on August 13th, 1910, when she was 90 years old.

The sun is shining and the birds are singing around. On such a 1 morning, a UFO lands in a forest. A boy called Bill is just watching it behind a tree. 

Suddenly, a tall alien* comes out of the UFO. He wears a silver suit and starts picking up 2 . One by one, he takes photos of them with a camera. When he finishes, he puts the flowers into a large box.

The alien thinks he sees something move and asks, "Is anybody there?" Bill doesn't answer. 

The alien 3 the looker and sees the boy behind the trees. "Oh, there is someone. Hello!" the alien says, "It's all right. You can come closer." 

"What are you doing?" Bill asks. 

"I'm 4 flowers," the alien says.

"Flowers? For what?" asks Bill.

"I'm going to take them back to my planet*," says the alien. 

"Aren't there any flowers on 5 ?" asks Bill.

"No, our planet doesn't have flowers for a long time." The alien says 6 , "We have too much litter, we cut down too many trees, 7 now it's like a desert*. There is almost no water any more. All of the flowers and trees that lived on our planet are gone." 

"That's terrible," says Jim "Is anyone doing 8 about it?" 

"Yes ... That's 9 I'm here and we want to find plants from other planets. We use them to learn about water. I believe someday water will come back to our planet." 

"Wow," Bill said. "What's the name of your planet?"

It's called Rozul," the alien says, "Long ago, it was very beautiful. If we work hard, someday Rozul will be 10 again." And then the alien goes back to the UFO. Bill says goodbye as the UFO slowly goes up into the air and flies away.
