1、河北定州中学2016-2017学年第二学期高一承智班英语周练试题(1)一、阅读理解One of my first memories as a child in the 1950s was a discussion I had with my brother in our tiny bedroom in the family house in Bethlehem, Pennsylvania.We had heard in school about a planet called Pluto. It was the farthest, coldest, and darkest thing a ch
2、ild could imagine. We guessed how long it would take to die if we stood on the surface of such a frozen place wearing only the clothes we had on. We tried to figure out how much colder Pluto was than Antarctica, or than the coldest day we had ever experienced in Pennsylvania.Pluto, which famously wa
3、s downgraded from a “major planet” to a “dwarf planet”(矮星)in 2006, captured our imagination because it was a mystery that could complete our picture of what it was like at the most remote corners of our solar system Plutos underdog discovery story is part of what makes it so attractive. Clyde Tombau
4、gh was a Kansas farm boy who built telescopes out of spare auto parts, old farm equipment and self-ground lenses. As an assistant at Lowell Observatory in Flagstaff, Arizona, Tombaughs task was to search millions of stars for a moving point of light, a planet that the observatorys founder thought ex
5、isted beyond the orbit of Neptune. On February 18,1930,Tombaugh found it. Pluto was the first planet discovered by an American, and represented a moment of light in the midst of the Great Depressions dark encroachment (入侵).Pluto is much more than something that is not a planet. Its a reminder that t
6、here are many worlds out there beyond our own and that the sky isnt the limit at all. We dont know what kinds of fantastic variations on a theme nature is capable of making until we get there to look.1Why did Pluto become famous in 2006 according to the passage?A. Because it lost its major planet st
7、atus.B. Because it disappeared in the sky.C. Because it was discovered by an American.D. Because it was proved to be the coldest planet in the universe.2What can be a suitable title for the text?A. An American Scientist: Clyde TombaughB. Pluto was First Discovered by a BoyC. Plutos Strange RomanceD.
8、 The Days I Spent with My Brother in Pennsylvania3What can we learn from the fourth paragraph?A. Clyde Tombaugh discovered the darkness in the Great Depression.B. Pluto was the only planet that was discovered by Clyde Tombaugh.C. Clyde Tombaughs job was to build telescopes for Lowell Observatory.D.
9、Clyde Tombaughs telescopes used for searching stars were very simple.4What does the underlined sentence in the last paragraph most probably mean?A. Pluto is no less than a planet in the solar system.B. Pluto is much more than a planet in the solar system.C. Pluto is more important than any other pla
10、net in the sky.D. Pluto is not a planet in the solar system, but it is more than a planet.Cancer is a terrible disease. Every year in the UK, more than 330,000 people get cancer, and doctors usually use a kind of therapy called radiotherapy to treat people. This treatment uses high energy X-rays to
11、destroy the disease, but the effects of treatment can be nearly as bad as the cancer. As the X-rays destroy the cancer cells, they also damage healthy cells that are next to them. Its like using a shotgun to kill an insect. When really important parts of a persons body are hurt by the X-ray energy,
12、it can have very bad results. It can also make more cancer grow in the damaged places in the future.A new therapy that uses protons(质子) instead of X-ray energy could be the answer to the problem. In a project called PRaVDA, scientists from the UK and South Africa are working to this. If X-ray energy
13、 is like a shotgun, then protons can work more like a laser. Scientists can make protons travel through someones body without hurting them, and only damage the cancer.The PRaVDA scientists use computers to make a 3-D model of the cancer cells to make sure the protons go to the right places. “Its mor
14、e accurate,” said Michaela Esposito, PhD, from the University of Lincoln.Building this technology was very difficult, though. Professor Nigel Allinson from the University of Lincoln, the project leader, has put together a team of many different kinds of scientists with different skills. Those skills
15、 were all needed to make what he calls “one of the most complex” medical machines ever. Its also 10 times more expensive than X-ray radiotherapy. Even so, Allinson believes that most cancer treatment will be done by protons in the future. “I think it will improve the quality of life of many cancer p
16、atients,” he says.5What point does the first paragraph make?A. Cancer is a really terrible disease.B. Lots of people get cancer every year in the UK.C. Radiotherapy isnt a perfect way to cure cancer.D. Radiotherapy is a commonly used therapy against cancer.6 What can be concluded about the new thera
17、py?A. Its much cheaper than X-ray radiotherapy.B. It depends on protons to locate the cancer cells.C. Damaging the cancer by replacing X-rays with lasers is much more accurate.D. It uses protons to damage the cancer cells without damaging healthy cells.7According to Professor Allinson, the new thera
18、py .A. will enable cancer patients to enjoy a better lifeB. will cure most cancers in the futureC. will ensure that cancer patients live longerD. will replace radiotherapy completely8 What can be inferred from the text?A. Science and technology are a double-edged sword.B. Not every cancer patient wi
19、ll be able to afford proton therapy.C. Radiotherapy is completely the wrong way to cure cancer.D. The complex medical machine mentioned will soon be put into use.Youll need to download free software to connect to our Secure Drop service.
