命题人: 刘春丽 审题人: 刘春丽 命题时间:2016- 02-15 编号:2015-2016yy0032019-2020年高二下学期文科英语限时训练003 含答案使用时间_班级_ 姓名_考号_一阅读理解 AOn a clear night, the sky is a wonderful thing. Is there life out there somewhere? Is there another place like Earth where life might exist? If so, where is it? And how far away is it?Recently, the Kepler spacecraft found “22b”, a planet about six hundred light years away. It is the first planet in a “habitable zone” outside the solar system. That means the planet orbits(环绕) a star like our sun, but it is not too close to it, nor too far away. Because of this position, Kepler-22b might have water, one of the main things needed for life. The newly-discovered planet is about two and a half times larger than the Earth. It is closer to its star than we are to the Sun, but 22bs sun is smaller than ours, and doesnt produce as much heat. Scientific instruments show the new planet could be made of gases, rocks or some kinds of liquids.The Kepler spacecraft was named in honor of Johannes Kepler, the seventeenth century German astronomer. It was designed to examine a small part of the Milky Way galaxy(星系)and search for places like the Earth. It was made to inspect over 150,000 stars and measure how bright they are. It looks to see if a stars brightness gets less over a short time. If a planet passes between Kepler and the star, it blocks out part of the light. That is what suggested to scientists that there is at least one planet orbiting the star. The instruments on Kepler show the new planet as a small, black dot moving across its sun. An important part of the Kepler experiment is on the Earth. After the spacecraft gathers information, scientists use the telescopes on the ground.Scientists have found over 2,300 new planets since Kepler was launched. Most are much larger, but it is the new planets distance from its star that is important. For life to possibly exist there, the planets temperature must not be too hot or too cold.1. What can we learn about Kepler-22b?A. It is the first planet in outer space where life may survive.B. It takes humans about 600 years to get there.C. It is made of gases, rocks and plenty of liquids.D. Water must have existed on it.2. The Kepler spacecraft was sent into space to_. A. show honor to Johannes KeplerB. look for Earth-like planets in the Milky Way galaxyC. observe the changes of a stars brightnessD. measure the brightest star among 150.000 stars3. In Paragraph 4 the author mainly tells us_. A.how the Kepler system shows a new planetB. if the Kepler system sees a new planetC. how the Kepler system worksD. why an important part of the Kepler system remains on the Earth4. What can we infer from the passage?A. Life may exist on the new planet in another form.B. It is colder on the new planet because its sun is smaller.C. The new planets distance from its star decides on the possibility of life existence.D. Life cant exist on planets which are much larger than the Earth. BIn Britain and other countries,young people sometimes take a“gap year”,a year off between high school and collegeThis idea never gained a big following in AmericaRecent news reports have suggested that interest may be growing,though there are no official numbers Charles Deacon, Dean of Admissions at Georgetown University in Washington,DC,estimates that in the current first-year class of 1,600 students,only about 25 decided to take a year offHe says this number hasnt changed much over the yearsMrDeacon says the most common reason for taking a“gap year”is to have a chance to travel,but he says international students may take a“gap year”to meet requirements at home for military dutySome high school graduates see a year off as a chance to recover after twelve years of required education,but it can also give students a chance to explore their interestsStudents hoping to be doctors,for example,could learn about the profession by volunteering in a hospitalMany colleges and universities support gap-year projects by permitting students to delay their admissionExpers say students can grow emotionally and intellectually as they work at something they enjoyThe Harvard admissions office has an essay on its Web site called“Time Out or Bum Out for the Next GenerationIt praises the idea of taking time off to step back,think and enjoy gaining life experiences outside the pressure of studiesIt also notes that students are sometimes admitted to Harvard or other colleges partly because they did something unusual with that time Of course,a gap year is not for everyoneStudents might miss their friends who go on directly to college,and parents might worry that their children will decide not to go to college once they take time offAnother concern is moneyA year off,away from h
