An Indian spacecraft's first attempt to make a soft, controlled landing in the moon's south polar region has ended in painful silence: Shortly before touchdown (降落), the robotic lander - part of the Chandrayaan-2 mission - fell out of contact with mission control(航天地面指挥中心). The Indian Space Research Organization says that the spacecraft stopped communicating with Earth when it was within 1.3 miles of the lunar surface. ''The Vikram descent (下降)was as planned, and normal performance was observed, up to an altitude of 2.1 kilometers, '' said Kailasavadivoo Sivan, ISRO's chairman, in a statement roughly half an hour after signal loss. ''The data is being analyzed.''
A successful landing would have made India just the fourth country to touch down anywhere on the lunar (月球的)surface, and only the third nation to operate a robotic rover (巡视器) there. Nevertheless, the Chandrayaan-2 mission's orbiter(航天器) remains safely in lunar orbit, with a year-long scientific mission ahead of it. Like any voyage to a world beyond Earth, Vikram's flight was a risky endeavor, requiring the lander to slow itself down to a near standstill(停止), scan for surface obstacles (障碍物) by itself, and then take steps to avoid them during touchdown. The majority of attempts to land robots on the moon have ended in failure, either during launch or on the way to the surface.
Following its launch on July 22, Chandrayaan-2 spent the last several weeks inching its way to the moon, ultimately entering lunar orbit on August 20. On September 2, Vikram separated from the mission's orbiter, and the newly freed lander began a series of braking maneuvers (刹车操作)to lower its orbit and ready itself for landing. Had things proceeded without a fault, Vikram and Pragyaan - the small solar-powered rover it carried - would have set down on the moon at a latitude of about 70 degrees South, on a highland between Manzinus C and Simpelius N.
This landing site was ''somewhere new that we haven't seen before, so that makes it another area for ground-truthing remote sensing data,'' Clive Neal, a lunar geologist, said in an interview before the landing attempt, ''It was going to certainly enhance our knowledge of what the moon is like in those areas, so it was going to be another very good place for science and exploration.''
1.What happened to the lunar lander according to paragraph 1?
A.It made a soft landing. B.It got data from the lunar surface.
C.It lost contact with Earth. D.It lowered itself at a wrong altitude.
2.Why was the Vikram's flight a risky endeavor?
A.It demanded higher technique.
B.There were not enough funds to support it.
C.Few Indian scientists agreed with the voyage.
D.No country has succeeded in landing robots on the moon.
3.What can we learn about Vikram from the third paragraph?
A.It entered lunar orbit four weeks after its launch.
B.It landed on the moon at an altitude of about 70 degrees South.
C.It separated from the mission's orbiter before entering the lunar orbit.
D.It lowered its orbit by starting the braking maneuvers to prepare for its landing.

What we know of prenatal development makes all this attempt made by a mother to mold the character of her unborn child by studying poetry, art, or mathematics during pregnancy seem totally impossible. How could such extremely complex influences pass from the mother to the child? There is no connection between their nervous systems. Even the blood vessels of mother and child do not join directly. An emotional shock to the mother will affect her child, because it changes the activity of her glands and so the chemistry of her blood. Any chemical change in the mother’s blood will affect the child for better or worse. But we can not see how a looking for mathematics or poetic genius can be dissolved in blood and produce a similar liking or genius in the child.
In our discussion of instincts we saw that there was reason to believe that whatever we inherit must be of some very simple sort rather than any complicated or very definite kind of behavior. It is certain that no one inherits a knowledge of mathematics. It may be, however, that children inherit more or less of a rather general ability that we may call intelligence. If very intelligent children become deeply interested in mathematics, they will probably make a success of that study.
As for musical ability, it may be that what is inherited is an especially sensitive ear, a peculiar structure of the hands or the vocal organs connections between nerves and muscles that make it comparatively easy to learn the movements a musician must execute, and particularly vigorous emotions. If these factors are all organized around music, the child may become a musician. The same factors, in other circumstance might be organized about some other center of interest. The rich emotional equipment might find expression in poetry. The capable fingers might develop skill in surgery. It is not the knowledge of music that is inherited, then nor even the love of it, but a certain bodily structure that makes it comparatively easy to acquire musical knowledge and skill. Whether that ability shall be directed toward music or some other undertaking may be decided entirely by forces in the environment in which a child grows up.
1.Which of the following statements is not true?
A.Some mothers try to influence their unborn children by studying art and other subjects during their pregnancy.
B.It is utterly impossible for us to learn anything about prenatal development.
C.The blood vessels of mother and child do not join directly.
D.There are no connection between mother’s nervous systems and her unborn child’s.
2.A mother will affect her unborn baby on the condition that ______.
A.she is emotionally shocked
B.she has a good knowledge of inheritance
C.she takes part in all kind of activities
D.she sticks to studying
3.According to the passage, a child may inherit ______.
A.everything from his mother
B.a knowledge of mathematics
C.a rather general ability that we call intelligence
D.her mother’s musical ability
4.If a child inherits something from his mother, such as an especially sensitive ear, a peculiar structure of the hands or of the vocal organs, he will _____.
A.surely become musician
B.mostly become a poet
C.possibly become a teacher
D.become a musician on the condition that all these factors are organized around music

An American spacecraft is moving closer to a dwarf planet(矮行星)called Ceres(谷神星). The American space agency's Dawn spacecraft is set to reach the planet-like object in March.
Space agency scientists will then place Dawn in an orbit(轨道) around the dwarf planet. Agency scientists want to know more about ice on Ceres. The spacecraft will gather clues about whether Ceres may have once had conditions to support life as we know it.
Dawn left Earth more than seven years ago on a trip to explore Ceres and another dwarf planet, called Vesta(灶神星). Both dwarf planets are in the main belt of asteroids(小行星), a group of large objects, between the planets Mars and Jupiter.
Marc Rayman is the chief engineer and director of the Dawn mission.
Scientists call Vesta and Ceres "protoplanets(行星) ". Mr. Rayman says they were in the process of becoming full-size planets when, in his words, "their growth was terminated(终止)."
Scientists believe Ceres is made of rock, and covered with ice.
The Dawn mission is based in Los Angeles, California. Scientists there send second-by-second commands to the spacecraft. They direct its every move, including telling it what pictures to take. Dawn will make a map of the dwarf planet. It will also try to discover how Ceres' surface has changed.
Carol Raymond is the deputy principal investigator(副首席研究员) of the project. He says Dawn made an unexpected discovery while orbiting Vesta.
"Instead of being bone dry, which we expected, there were patches on the surface of Vesta that showed significant amounts of water bound in the rocks and possibly even free water that could have flowed on the surface in the past."
She says that if Earth's water came from wet worlds like Vesta and Ceres, then life could have developed there, too.
If Dawn finds that the environment of Ceres could have supported life, scientists may seek to explore the dwarf planet with other scientific instruments.
Dawn will gather information about Ceres until the middle of 2016. It will then continue to orbit the small planet.
1.Which of the following about spacecraft Dawn is true?
A. It was sent into space in 2008.
B. It is orbiting around the dwarf planet Ceres.
C. Its destination is just the dwarf planet Ceres.
D. It will gather information about Ceres until early 2016.
2.What’s the meaning of the underlined word “patches”?
A. spots B. roles C. sorts D. kinds
3.What do we know about Vesta?
A. It is in the main belt of asteroids between the planets Mars and Venus.
B. It is another dwarf planet which Dawn will explore.
C. It is becoming a full-size planet.
D. It is made of rock, and covered with ice.
4.The passage mainly tells us ______.
A. Spacecraft , Dawn, is researching Ceres.
B. What Spacecraft , Dawn, is.
C. NASA Spacecraft, Dawn, is moving closer to a 'Dwarf Planet'.
D. How Dwarf Planet research program is carried out.

When I decided to apply for a summer job, I was a freshman. After several attempts(尝试), I got an interview with Dave Hensley, a manager in the games department at Cedar Point Amusement Park. I was a very shy and quiet boy, but I put aside my shy nature for the interview, and was as outgoing(外向的) as I knew how to be. Apparently(明显地)it worked. I was informed (通知) to go to the park the next day. However, when I arrived, Dave told me he was assigning (分派) me to be a guesser. That position required standing all alone, speaking to thousands of people over a microphone. I never dreamed Dave would assign me to that position.
Dave must have sensed my fear as he said, “Don’t worry. I’m sure you’ll do fine.” Then he took me to the Guessing Game location in an area of the park. Along the way, Dave talked to me, trying to improve my confidence. He told me to just relax and be myself, and then the microphone was put into my hand.
My mind was disorderly, but I knew I wanted to work at Cedar Point, and that desire meant I had to make it. After thirty minutes, Dave took the microphone and gave it to another guesser. He turned to me and said, “Well, at least you’re not afraid of the microphone!” Thanks to Dave’s trust and encouragement, I went on to become a very successful guesser. His support in helping me overcome that fear improved my life in more ways than Dave could ever imagine. In that same spirit, I successfully completed my Master’s degree in electrical engineering which I had once wanted to give up.

NASA said its Kepler spacecraft has spotted ''Earth's bigger, older cousin'': the first nearly Earth-size planet to be found in the habitable zone of a star similar to our own.
Though NASA can’t say for sure whether the planet is rocky like ours or has water and air, it's the closest match yet found.
The planet, Kepler-452b, is about 60% bigger than Earth, NASA says, and is located in its star's habitable zone, where life-sustaining liquid water is possible on the surface of a planet.
A visitor there would experience gravity about twice that of Earth's, and scientists say the possibility of it having a rocky surface are ''better than ever''. While it's a bit farther from its star than Earth is from the sun, its star is brighter, so the planet receives about the same amount of energy from its star as Earth does from the sun.
Kepler researcher Jeff Jenkins said, ''The planet almost certainly has an atmosphere, although scientists can't say what it's made of. But if the assumptions are correct, kepler-452b's atmosphere may be thicker than Earth's. ''
It takes 385 days for the planet to orbit its star. ''Because it has spent so long orbiting in this zone—6 billion years—it's had plenty of time to brew life,'' Jenkins said.
''That's an opportunity for life to arise, if all the necessary ingredients and conditions for life exist on this planet, '' he said in a statement.
Kepler-452b is too far away for humans to visit. But the discovery of this new Earth-like planet can tell us a lot about what’s possible for the future of space travel. ''The next step in the process is to do follow-up missions to find planets similar to kepler-452b, but much closer to Earth, '' said Peter Coughlin, a Kepler research scientist. ''We could do a lot more research into those planets, and even start to think about visiting one day. ''
1.The researchers are sure that Kepler-452b ________.
A.is larger than Earth B.has an atmosphere
C.has air and water D.has many rocks
2.What is the similarity between Kepler-452b and the Earth?
A.They are both located in the sun's habitable zone.
B.Their distances from the sun are almost the same.
C.Their atmospheres are made of the same compositions.
D.They get almost the same amount of energy from their stars..
3.The underlined word ''brew'' in paragraph 6 most probably means ________.
A.improve B.endanger
C.produce D.protect
4.What should be the best title for the text?
A.Kepler-452b Is Compared to the Earth.
B.NASA Discovers a New Earth-Like Planet.
C.A Spacecraft Was Launched to Find Super-Earth.
D.A New Planet With Life Is Discovered.
