Today, most of Mars is as dry as a desert except for ice deposits in its polar regions. Where did the rest of the water go?Some of it disappeared into space. Water molecules, beaten by particles of solar wind, broke apart into hydrogen and oxygen atoms, and those, especially the lighter hydrogen atoms, sped out of the atmosphere, lost to outer space.But most of the water, a new study concludes, went down, sucked into the red planet's rocks. And there it remains, trapped within minerals and salts. Indeed, as much as 99% of the water that once flowed on Mars could still be there, the researchers estimated in a paper published this week in the journal Science. Bethany Ehlmann, a professor of planetary science at the California Institute of Technology and one of the authors of the paper, said that as the rocks are altered by liquid water, water molecules become incorporated (并入) into minerals like clays.The data and simulations indicated that the water on Mars was almost all gone by 3 billion years ago, around the tune on Earth when life consisted of singlecell microbes in the oceans. Without a time machine, there is no way to observe directly how much water was on a younger Mars more than 3 billion years ago. But the hydrogen atoms floating today in the atmosphere of Mars preserve a ghostly hint of the ancient ocean.On Earth, about 1 in 5, 000 hydrogen atoms is a version known as deuterium (重氢；氢的同位素) that is twice as heavy because its nucleus contains both a neutron and a proton. But on Mars, the concentration of deuterium is markedly higher, about 1 in 700. Scientists at the NASA Goddard Space Flight Center who reported this finding in 2015 said this could be used to calculate the amount of water Mars once had.1．Why can't water be found on Mars now except for ice deposits in polar regions?A．Because it was transformed into deuterium.B．Because it was beaten into particles by solar wind.C．Because most of it was integrated and some disappeared.D．Because it broke down into hydrogen and oxygen atoms.2．What is implied about deuterium in the last paragraph?A．It is twice the weight of hydrogen.B．Its nucleus contains a neutron and a proton.C．Its concentration on Earth is markedly higher than on Mars.D．It enlightens scientists on the measurement of water on Mars.3．In which section of a newspaper may this article appear?A．Science. B．Travel.C．Entertainment. D．Education.4．What can be a suitable title for the text?A．Mars: Once Wet, Now DryB．Atoms: Hydrogen or DeuteriumC．Microbes: Singlecell or MulticellD．Water Vanished: This Might Be Where It Went篇章导读：本文是一篇说明文。

Why does the earth have life while the other planets don't ？For one thing ，the earth is just the right temperature. As the third planet from the sun ，the earth seems to be just the right distance away. The planets which are closer to the sun are so hot that their surfaces bake(烘烤)in the sun. The farthest planets are cold balls.When the earth developed ——which scientists believe may have happened about 4 billion years ago ——many gases covered the earth. The gases caused the earth to be hot. But something wonderful happened. The temperature was just right for thick clouds to form. It rained very hard for a very long time. This gave the earth its oceans. Water made it possible for plants to grow. The plants created oxygen in the atmosphere. Oxygen is the gas that humans and animals breathe.Only one other planet in the solar system seems to be something like the earth. That planet is Mars (火星). Mars is smaller than the earth ，and it is quite a bit cooler. But it is not too cold for humans. On some days ，the temperatures are as low as a winter day in the northern United States. If you wore a special spacesuit ，you could walk around on Mars. You would have to bring your own air to breathe ，because the air on Mars is too thin to breathe.Mars has the largest volcano(火山) in the solar system. It is sixteen miles high. The highest volcano on the earth is five miles high. The most unexpected(未预料到的) sight on Mars is dried-up river beds. Scientists believe that Mars was once much better than itis now. Does this mean there could have been living things on Mars ？Scientists are not sure ，but there has been no sign so far.21. Which of the following is NOT the reason that the earth has life? A. The earth is just the right temperature.B. The volcanoes on the earth are lower than those on Mars.C. There is oxygen in the atmosphere of the earth.D. The earth seems to be just the right distance away from the sun.22. The underlined phrase “the third planet” in the first paragraph refers to_______. A. the Sun B. the Moon C. the EarthD. the Mars23. Which of the following about the Mars is NOT true? A. There could have been living things on Mars. B. Mars has the largest volcano in the solar system. C. There is almost no oxygen in the air on Mars.D. Mars is smaller than the earth ，and it is quite a bit cooler.BDamage to Ozone layer Gets WorseIn the middle of winter, when snow is falling in many parts of the United States, scientists have sounded a warning to people who plan to spend many hours in the sun this summer. The warning is: The sun’s summertime rays are more d angerous than once thought.A team of scientists from 80 nations recently reported to the United Nations that a layer of ozone (臭氧层) in the atmosphere, which protects humans from harmful levels of ultraviolet （紫外线） radiation, will be thinner over the United States this summer. The thinner layer allows more ultraviolet rays from the sun to reach Earth. The extra amount of ultraviolet radiation could cause an increase in the number of cases of skin cancer.Scientists first became concerned about the ozone layer in the mid-1980s when a hole was discovered in the layer above Antarctica during the winter. The hole was caused by chemicals used in refrigerators and air conditioners. When these chemicals are sent out into the atmosphere, they produce gases that destroy the ozone.Concern about the protective ozone layer rose more recently when data(数据) from satellites and ground stations showed that ozone levels were dropping over areas other than Antarctica. Low ozone levels were recorded in the spring and summer over the United States and over other populated areas in the world.Although many countries have already begun stopping the use of ozone destroying chemicals, the new findings are expected to advance the timetable for a total ban(禁止) of the chemicals.24. The scientists have observed the ozone layer ________.A. since 1980B. since last winterC. for more than 20 yearsD. for about one year25. The ozone layer in the atmosphere can ________.A. do a lot of good to human beings in many ways.B. protect humans from diseases caused by bad weather.C. do a lot of harm to human beings in the summer-time.D. protect humans from harmful levels of ultraviolet radiation.26. Scientists first found that there was a hole in the ozone layer ________.A. above Arctic during the winter in the mid-1980sB. above Antarctica during the winter in the mid-1980sC. over somewhere in the north of the equator in 1980D. over the U.S.A in the summertime in the mid-1980s27. The damage to the ozone layer was caused by ________.A. the changeable weatherB. ozone-destroying chemicalsC. chemicals from refrigeratorsD. chemicals from air conditioners四、课文语法填空（共10小题；每小题1.5分，满分15分）No one knows ___28__ (exact) how the earth began, as it ___29__ (happen) so long ago. However, according to a widely __30__ (accept) theory, the universe began with a “Big Bang” that threw matter in all ___31__ (direction). After that, atoms began to form and combine to create stars and other bodies.For several billion years after the “Big Bang”, t he earth was still just a cloud of dust. What it was to become was uncertain until between 4.5 and 3.8 billion years ago when the dust settled into __32__ solid globe. The earth became so violent that it was not clear __33__ the shape would last or not. It exploded loudly with fire and rock. They were in time __34___ (produce) carbon, nitrogen, water vapour and other gases, which were to make the earth’s atmosphere. ___35_ is even more important is that as the earth cooled down, water began to appear on its surface.What many scientists believe is that the continued presence of water allowed the earth to dissolve __36__ (harm) gases and acids into the oceans and seas. This produced a chain reaction, which made __37__ possible for life to develop.五、书面表达（满分25分）假设你是李华，最近从报纸上得知2017年敦煌文博会“Silk Road (Dunhuang) International Cultural Expo” 将于9月举行，组委会现面向全社会招募志愿者，要求英语口语流利，了解丝路文化及国外习俗等。

In fact，they were shot from 1914 through 1916，most of them after a disastrous shipwreck(海难)，by a cameraman who had no reasonable expectation of survival. Many of the images were stored in an ice chest，under freezing water，in the damaged wooden ship.The ship was the Endurance，a small，tight，Norwegianbuilt threemaster that was intended to take Sir Ernest Shackleton and a small crew of seamen and scientists，27 men in all，to the southernmost shore of Antarctica's Weddell Sea. From that point Shackleton wanted to force a passage by dog sled(雪橇) across the continent. Thejourney was intended to achieve more than what Captain Robert Falcon Scott had done. Captain Scott had reached the South Pole early in 1912 but had died with his four companions on the march back.As writer Caroline Alexander makes clear in her forceful and wellresearched story The Endurance，adventuring was even then a thoroughly commercial effort. Scott's last journey，completed as be lay in a tent dying of cold and hunger，caught the world's imagination，and a film made in his honor drew crowds. Shackleton，a onetime British merchantnavy officer who had got to within 100 miles of the South Pole in 1908，started a business before his 1914 voyage to make money from movie and still photography. Frank Hurley，a confident and gifted Australian photographer who knew the Antarctic，was hired to make the images，most of which have never before been published.1．What do we know about the photos taken by Hurley?A．They were made last week.B．They showed undersea sceneries.C．They were found by a cameraman.D．They recorded a disastrous adventure.2．Who reached the South Pole first according to the text?A．Frank Hurley.B．Ernest Shackleton. C．Robert Falcon Scott. D．Caroline Alexander.3．What does Alexander think was the purpose of the 1914 voyage?A．Artistic creation. B．Scientific research. C．Money making. D．Treasure hunting.六、完形填空I suffered a serious head injury as a kid. It led to a constant(1)even in a special reading class.
