Water is a human right and everyone should have their share. Yet more than 700 million people around the world have trouble getting clean, safe water.Treating wastewater is a good way to provide fresh water for us. And it also helps the environment by keeping waste out of rivers and oceans. 80% of wastewater around the world is not treated at all, and it is running into oceans. But now we have got the technology to treat and reuse the wastewater.While 75% of our planet is covered with water, only about 2% is fresh water—that comes from rivers, lakes, ice and snow. The rest, 98% of the water, is in seas and oceans. It is too salty to drink. Then desalination businesses come in. More than 19,000 factories have been built around the world, mostly in coastal countries. They process (加工) more than 92 million tons of water every day. But the technology they use requires a lot of energy.Scientists are working to create a less costly technology. They want to produce 20 times more clean water and make sure everyone has enough.

The boy didn’t quite 20 but he believed in his teacher and kept training.Several more months later, the teacher took the boy to his first tournament (锦标赛). The boy easily won his first two matches. The third match was 21 , but after some time, he used his one move to win the match.Gradually, the boy was now in the finals. This time, his opponent was bigger, stronger and more experienced.

She told the children on the first day that she loved them all the same. But that was a lie. There in the front row was a little boy named Teddy Stoddard. He didn’t get along well with the other children and he always needed a bath. She did not like him.Then Mrs. Thompson got to know that Teddy was actually a very good boy before the death of his mother. Mrs. Thompson was ashamed of herself. She felt even worse when, like all her other students, Teddy brought her a Christmas present too. It was his mother’s perfume.Teddy said, “Mrs. Thompson, today you smell just like my Mom used to.” After the children left, she cried for at least an hour. On that very day, she stopped being busy teaching reading, writing and math. Instead, she began to care more about the children.Mrs. Thompson paid more attention to Teddy. The boy’s mind seemed to come alive. The more she encouraged him, the faster he improved. By the end of Grade 6, Teddy had become one of the smartest children in the class.Six years went by before she got a note from Teddy. He wrote that he had finished high school, third in his class, and she was still the best teacher he had ever had in his whole life. He went to college. Mrs. Thompson got two more letters from him with the last one signed: Theodore Stoddard, M. D．(医学博士).The story doesn’t end there. On his wedding day, Dr. Stoddard said, “Thank you, Mrs. Thompson, for believing in me. You made me feel important and showed me that I couldmake a difference.”Mrs. Thompson, with tears in her eyes, said, “Teddy, you have it all wrong. You were the one who taught me that I could make a difference. I didn’t know how to teach until I met you.”26．What did Mrs. Thompson do on the first day of school?A．She made Teddy feel ashamed.B．She asked the children to play with Teddy.C．She changed Teddy’s seat to the front row.D．She told the class something untrue about herself.27．In what way did Mrs. Thompson change after she received the gifts?A．She taught fewer school subjects.B．She became stricter with her students.C．She no longer liked her job as a teacher.D．She cared more about educating students. 28．Why did Teddy thank Mrs. Thompson at his wedding?A．She had kept in touch with him.B．She had encouraged him.C．She had sent him Christmas presents.D．She had taught him how to judge people.Liang Xianghua, a 22-year-old girl from Guangxi University, has been well-known in China for her sand painting since her first work was used by CCTV.“Sand paintings really attracted me while I was watching a video performance. I was surprised by how this artwork melted people’s heart in minutes,” said Liang. “I fell in love with the way the sand pictures, music and the light connected with each other to make a flow of feelings. You can express things freely.”In order to learn the skills, Liang practised for several hours every day. She said that she couldn’t even do the first step well of throwing sand onto the glass. But she didn’t give up.After finding success with her first show, she was invited to do many performances. This made her quite tired. She decided to give a stop and focus on her study. But an invitation from Malaysia changed her mind just as she was about to wash the sand from her hands. This spring, she was invited by a Malaysia middle school to give a performance. Liang didn’t want to do a live show, but agreed to do a video for the school showing its development over the years.She received praise for her work and the performance was described as an eye-opener for the students. This made her wonder if her art would be more meaningful if she made it for the poor students.As a volunteer this time, she plans to take part in a summer programme offering help to pupils in a mountain area, and give the most wonderful show in her life.29．Why did Liang fall in love with sand painting?A．Because she wanted to be famous.B．Because she wanted to be a volunteer.C．Because sand paintings melted her heart.D．Because she loved watching video programmes.30．What’s the purpose of Paragraph 3?A．To tell us that Liang is good at making sand pictures.B．To explain why Liang fell in love with sand pictures.C．To show that Liang’s success comes from hard work.D．To express that Liang enjoys throwing sand onto the glass.31．What does the underlined sentence in Paragraph 4 imply?A．Liang decided to wash the sand off her sands.B．Liang wanted to make a new sand painting.C．Liang wanted to do voluntary work in summer,D．Liang decided to give up doing sand paintings.32．What is the best title for the text?A．How to Draw A Sand Painting B．Liang and Sand PaintingC．A Special Painting D．Ways to Help Poor KidsFrom tiny seeds, great discoveries grow. Recently, China’s Chang’e 4 moon lander(登月舱) carried a mini-garden. It became home to the first plant to grow on another world.This is yet another success for Chang’e 4. On January 3, 2019, the probe (探测器) became the first lander to touch down on the far side (背面) of the moon. This is the unknown face of the moon that is always looking away from us, so we never see it from down here on the earth. Although it is often known as the dark side of the moon, the far side actually gets as much sunshine as the near side. For example, when all we can see is a new moon, the far side of the moon is in full sunlight.Part of Change 4’s task is to see how a moon base could be built for humans, including exploring whether humans could grow food and other plant products there. Chang’e 4 carried a mini-garden with air, water and soil with seeds planted in it. When plants shoot on the earth, their stems grow away from the gravity (the force that keeps your feet on the ground), and so they always shoot upwards. The moon’s gravity is a sixth as strong as the earth’s, so Change 4’s experiment was a test: would the earth plants know which way was up on the moon? Four days after landing, a tiny cotton shoot showed that they know.Night has now fallen on the far side of the moon, sunlight will not return until the start of February, both on the near and the far sides. As a result, the cotton shoots died. Besides the darkness, the plants can’t stand the cold (it can drop to -170℃ on the moon at night). However, the experiment is a success, since it has proved that it is possible for plants to grow in space. 33．Which of the following is TRUE about Change 4?A．It carried a mini-garden.B．It landed on the near side of the moon.C．It built a moon base on the moon.D．It found plants oh the moon. 34．What can we know from the text?A．The far side of the moon gets less sunlight.B．We can see the far side of the moon from the earth.C．The stems fail to grow away from the earth’s gravity.D．The earth plants know the way to grow on the moon.35．What can be inferred from the text?A．Plants have been grown on the moon.B．It is perfect to do experiments on the moon.C．The cotton shoots can last for weeks on the moon.D．We can see a new moon at the start of February.36．In which section of a magazine can you read the text?37．________ can join the three-day summer program.A．A kid of 6B．A boy of 14C．A girl of 18D．A man of 26 38．If there is a rainstorm on 12th July, Program A will start on ________.A．Sunday B．Monday C．Tuesday D．Wednesday 39．Two members and one non-member should pay ________ for the program.A．$710B．$690C．$480D．$750 40．What can we know from the passage?A．Youth Explorer is the name of the program.B．More than 15 students are in each program.C．We can only see three kinds of animals in the program.D．You need to hand in an application form for the program.四、阅读还原5选5The salmon (大马哈鱼) is a very strange fish. It is born in a river. But the young salmonto the river where it was born. A grown-up salmon weighs about 25 pounds and is nearlybegin a great journey. Each salmon is heading for the river where it was born. A salmon may be a thousand miles from where its life began. Yet it is able to return to that place.43 The salmons are also food for some other larger fish. Some are caught by fishermen. The salmons that are left keep swimming. After they enter the rivers, they head upstream (向上游). If rocks and waterfalls are in their way, the salmons leap (跳) over them.44 It leaps by swimming at full speed under water, then rising to the surface. Almost the whole body of a salmon is made of muscles. It is these powerful muscles that make the salmon fit for fast swimming, quick turning, and high leaping out of the water.Some salmons reach the river in summer, others in the early autumn. 45A．As the salmons swim, larger fish attack them.B．For another two years it lives in the sea and becomes full grown.C．They have swum hundreds, even thousands of miles to return.D．The female salmon will not lay eggs in the Pacific Ocean.E．A salmon can leap up a fall as high as 10 feet.五、短文首字母填空根据下列语篇以及所给单词的首字母写出所给单词。
