If anyone can be called a scientific giant after Albert Einstein, that person must be Stephen Hawking. He was born in Oxford, England on Jan. 8th, 1942. What a pity On March 14th, 2018, the world-famous British scientist1in Cambridge, UK.

    After leaving high school Hawking went first to Oxford University 2he studied physics and then went to Cambridge University where he studied cosmology(宇宙学). As he himself admitted, he didn't work hard. And he did 3work. However, he always enjoyed thinking everything around him, especially the universe. Today, he is called the King of the Universe.

    It was at the age of 21 that Hawking first4something was wrong with him. He started to bump into some things. When he visited his family at Christmas time, his mother was so worried that she 5 him see a doctor. Hawking was sent to hospital for tests. Finally, the result came back. He6to have motor neuron disease(运动神经元病), an incurable illness which would make him unable to speak, breathe or move 7the help of a machine. Doctors said they had no ways to help him. He might die before 23.

    8, Hawking became very depressed. After a while, though, he began to see his life in a different way. As he later wrote, “After my illness was diagnosed(诊断), I was very9with life. There had not seemed to be anything worth doing. But shortly after I came out of hospital, I suddenly realized that there were a lot of worthwhile(值得做的) things I could do."Then Hawking got married and found a job at Cambridge University as a professor. We strongly believe that his story shows that 10, how had their situation is, should lose hope. “Life is not fair.” He once said, “You just have to do the best you can in your own situation.”

    About twenty of us had been fortunate enough to receive invitations to a film-studio(影棚) to take part in a crowd- scene. Although our "act" would last only for a short time, we could see quite a number of interesting things.

    We all stood at the far end of the studio as workmen prepared the scene, setting up trees at the edge of a winding path. Very soon, bright lights were turned on and the big movie-camera was wheeled into position. The director shouted something to the camera operator and then went to speak to the two famous actors nearby. Since it was hot in the studio, it came as a surprise to us to see one of the actors put on a heavy overcoat and start walking along the path. A big fan began blowing tiny white feathers down on him, and soon the trees were covered in "snow". Two more fans were turned on, and a "strong wind" blew through the trees. The picture looked so real that it made us feel cold.

    The next scene was a complete contrast(对比). The way it was filmed was quite unusual. Pictures taken on an island in the Pacific were shown on a glass screen. An actor and actress stood in front of the scene so that they looked as if they were at the water's edge on an island. By a simple trick like this, palm trees, sandy beaches, and blue, clear skies had been brought into the studio!

    Since it was our turn next, we were left wondering what scene would be prepared for us. For a full three minutes in our lives we would be experiencing the excitement of being film "stars"!

①China published the world's first highly clear lunar geologic (地质的) atlas (地图集) on April 21. According to the Chinese Academy of Sciences (CAS), it will provide up-to-date information for future lunar research and exploration.

②"These maps will help choose locations for future lunar research stations," Ouyang Ziyuan, a well-known lunar scientist, said. "They can also help us better know about the Earth and other planets in the solar system, like Mars."

③The world has seen great progress in the field of lunar science over the past half a century. However, the lunar geologic atlas that was developed during the Apollo Program remained unchanged. "As lunar geologic studies develop, those old maps can no longer satisfy future needs," said Liu Jianzhong, a CAS researcher.

④Since 2012, Ouyang and Liu have led a team of scientists from several research centers in compiling (编制) this atlas. Their work was mainly built on information gained from China's Chang'e Program. Information from other research projects and international tasks was also used.

⑤The new geologic atlas, which is published in both Chinese and English, presents a scale (比例尺) of 1: 2.5 million. Compared with the 1:5 million scale lunar maps from the US in 2020, these larger scale maps show more details. As well as the geologic history of the moon, they provide information on its 14 types of structures (结构) and 17 types of rocks. A total of 12,341 impact craters (撞击坑) and 81 impact basins have also been marked.

⑥This atlas is set to serve many useful purposes, such as lunar resources research and science education. Liu said the upcoming Chang'e-6 task would also use the atlas. "Our maps can help the research by providing scientific support," he explained.

⑦"Compiling the atlas was a huge task, which included years of effort from a large number of researchers," said Gregory Michael, a German scientist. "It will be a starting point for every new question of lunar geology."

Why do people play football? It's a(n 1 game and it's dangerous too. Twenty-two men fight2 ninety minutes to make as3 goals as they can. They get4 black eyes, bruise(擦伤) and broken bones than they do5 points. Football players must be mad(发疯的). 

And why do people watch football? They6 be mad too. They certainly7 and scream like8 . I'm afraid9 near a football field when they are playing a game. The crowds are10 . 

I'd11 stay at home and watch TV. But what happens when I turn it 12 ? They're showing a football game. So I turn on the radio. What do I13 ? The 14 football scores. And what do I see when I open a newspaper? Pictures of football players, interview(采访) with     15 players, scores of football games. 

 There are about 180,000 words in the Oxford English Dictionary, but most of us only know a few thousand of them. That's why we often want to get the answer of" how to improve vocabulary". Here are some ways to improve your vocabulary.

Watch English movies

 Watching the English movies is a vocabulary booster. If you see the movie of your favourite book, you will have a better understanding of the words in it. You read something and then you see it on the screen. You will remember better because you have a visual representation.

Get out of the house

 Going to new places and doing something new are great ways to build new knowledge. When you open your eyes to new people and things, you also get new words from them.

Join a book club

 In a book club, you have to spend some time reading. Read as many kinds of books as you can and you will learn more new words in different areas. Don't forget to write the new words down. Try to remember and use them.
