三、阅读理解（共15小题;每小题1分，满分15分）
A
Many people dream of traveling into outer space. However, spending too much time in space may cause health problems, according to NASA. That’s why astronauts shouldn’t spend more than six months on the International Space Station (ISS) at a time.
Muscle（肌肉）and bone loss
In a weightless environment, astronauts don’t need to use their muscles to support themselves so their muscles start shrinking. To keep their muscles strong, astronauts need to exercise about 2 hours each day on the ISS.
Sleep disorder（混乱）
In space, the sun rises every 90 minutes. It is hard for astronauts to get used to this light-dark cycle when they sleep. Also, they need to sleep in a sleeping bag that is fixed to a wall, and it is uncomfortable.
Astronauts now have individual sleeping pods（分离舱）that help shut out some of the light. Still, studies have found that most astronauts only sleep about six hours each night, even though they should have eight and a half hours.
Brain changes
Scientists have found that the position of the brain changes during spaceflight. It can affect how the brain deal with how we see, stay balanced and move around. That’s why some astronauts can’t control their movement and balance after returning to the Earth. Scientists have also found that astronauts may get used to this change after going on more spaceflights. But they still need to do more research.
26. According to the passage, astronauts may have the following health problems Except____________.
A. bone loss B. brain changes C. sleep disorder D. headache
27. Astronauts may have muscle problems after returning to the Earth because_______________.
A. they seldom walk while in space
B. they are too busy to exercise in space
C. they don’t have enough room to exercise in space
D. they don’t need to use their muscles to support themselves in space
28. Astronauts sleep in individual sleeping pods to_______________.
A. stay warm at night B. shut out light
C. enjoy a quiet place D. avoid moving around
29. The underlined word “shrinking” in the second paragraph means______________.
A.萎缩 B.改变 C.消失 D.膨胀
30. The best title of this passage is____________.
A. Sleep Disorder in Space B. Brain Changes in Space
C. Muscle and Bone Loss in Space D. Health Problems in Space
B
Most of the universe is made up of a kind of matter. It's called "dark matter". None of us have ever seen it, and It's also very difficult to study.
Past research suggested there is more dark matter around younger galaxies (星系)than the ancient ones from the early days of the universe, but where did the dark mater come from After studying some 1,500 galaxies, researchers led by Alfred Riley found the amount of dark matter around these huge stars and planets is about the same as it ever was.
We can’t see dark matter in space because it doesn't reflect(反射)light, but we can study it by studying the influence the matter has on all around it. It gives a pull, just like "normal" matter.
By explaining the size of a galaxy and the speed at which stars on its edges(边缘)are moving, scientists can learn how much dark matter is around it.
Recently, scientists use the same way to study many hundred galaxies, both young and old. They believe there’s not much of a difference in the amount of dark mater between ancient galaxies and much younger ones.
However, not all of them fully agree with this new finding. The model researchers used has been called into question, especially as it relates to measurements(测量) of faraway high-mass (高质量的)galaxies which have been studied by others searching for dark matter.
Well have to wait and see how this all goes, but the results are certainly interesting and will no doubt further the conversation about where the universe's dark mater lies.
31. What is most of the universe made up of
A. Dark matter. B. Bright stars. C. Young galaxies. D. Huge planets.
32. How can scientists study dark matter
A. By visiting the faraway galaxies.
B. By getting some dark matter in space.
C. By studying the influence it has on all around it.
D. By using a special model to measure it.
33. What does the underlined word “it” in the fourth paragraph refer to
A. The planet. B. The galaxy. C. The matter. D. The universe.
34. Which of the following is TRUE about dark mater around younger or ancient galaxies
A. There is more dark matter around young galaxies.
B. There is more dark matter around ancient galaxies.
C. The amount of dark matter around them is almost the same.
D. So far, there is still much to discuss about it.
35. What would be the best title for this passage
A. The magic universe B. New findings in space
C. The secret of nature D. Searching for dark matter
C
What will astronauts eat when a space trip takes years “Lots of fresh vegetables,” says Br. Janet Williams, whose team have spent the last 10 years learning how to grow plants in a space station. And it’s a good thing that she has already started her work, because space gardening can be really hard.
As usual, astronaut George White looked into the closed plant room. He had planted Dr. Williams’s quick-growing seedlings in it, but none of the stems were showing. He opened the room to check and found the problem. The stems weren’t growing upward and the roots weren't growing downward. On Earth, gravity（重力）helps a plant’s stems and roots to find “up”and “down”. However, in the space station, there was almost no gravity.
Dr. Williams suggested a solution: give the plants more light, as plants also use sunlight to find their way. And it worked. When the plants had more light, the stems turned up and the roots went down.
Now Dr. Williams was free to worry about the next problem:Would her baby plants live to flower Can we grow food on a space journey
Many plants died in the space station. Dr. Williams thought she knew why: the space plants were hungry for air. Plants live by taking up CO2 from the air. Since a plant uses it up in the air around, the plant needs moving air to bring more CO2 close to its surface! On Earth, the air is always moving. Gravity pulls down cold air, and warm air rises. And with these air movements, plants get enough CO2.
Many earlier experiments with plants in space had used closed rooms.Dr. Williams tried a new greenhouse that had a fan to keep the air move. The plants loved it. They flowered and even produced more seeds. Using Dr. William’s method, astronaut George completed the first seed-to-seed experiment in space, and moved one plant closer to a garden in space.
“And this.” says Dr. Williams. “is good news for long-term space travel.”
36. Why have Dr Williams’s team tried to grow plants in space
A. To produce fresh air for astronauts.
B.To help astronauts relax themselves.
C.To provide food for long space journeys.
D.To make the space garden more beautiful.
37. How did light help solve the problem mentioned in Paragraph 3
A. It caused the gravity to change.
B. It encouraged the plants grow faster.
C. It helped the plants to grow in the right direction.
D. It showed the astronauts where to plant vegetables.
38. Why did many plants die in the space station
A. The light was too strong. B. There was too much CO2.
C. There was not enough room to grow. D. The air condition was not good enough.
39. The underlined word “it” in Paragraph 7 refers to
A. the moving air B. the closed room C. the space journey D. the space garden
40. What can we learn about Dr. Williams’s team from the passage
A. They mainly live on fresh vegetables.
B. They have successfully built a space garden.
C. They invented a special fan for their greenhouse.
D. They have worked on space gardening for many years.

For centuries, human beings have dreamed of traveling into space, orbiting（围绕…运行）our little blue planet, and enjoying amazing views of sunrises and sunsets. And soon, it seems that our dream will finally come true, as a US tech company Orion Span announced that it planned to start the first hotel in space and it will be ready to welcome guests from the Earth.
The space hotel, Aurora Station, will orbit 320 kilometers above Earth.circling it every one and a half hours.It can hold two crew members（工作人员）and four guests.The crew members will likely be former NASA astronauts who worked on the International Space Station.However,each guest must pay at least $9.5 million (60 million yuan) for a 12-day stay at the hotel.
Once aboard the Aurora Station, guests will find many exciting things to do. According to Orion Span, guests can enjoy the excitement of zero-gravity as they fly throughout the space hotel. They can watch 16 sunrises and sunsets every day and view the northern and southern auroras（极光）through the windows. They can take part in research experiments like growing food, and even take it home as a souvenir. And there’s a possibility that they can contact their families and friends on Earth through a high-speed Internet connection.
But most importantly, the trip will offer areal sense of what it's like to live in space. “The premise（前提）of Aurora Station is for guests to live, feel, and breathe what it’s like to be an astronaut,” Frank Bunger, CEO of Orion Span, told the Robb Report. “The food and drinks are freeze-dried products. It’s not going to be five-star dining ... Fire and gas don’t work the same way in space as they do on Earth."To better prepare guests for space-travel, the company will offer a three-month training program that helps guests understand basic spaceflight, orbital mechanics（轨道力学）and life in the pressurize environment of space.
Some may have doubts about he project, but the company even has plans to turn part of Aurora Station into private flats. “Future Aurora owners can live in, visit, or sublease（转租）their space flat,” Bunger said. “This is an exciting frontier（待开发的领域）and Orion Span is proud to pave the way.

We have always been interested in the moon. 2000 years ago, people already knew it m______71______ around the Earth and where it would be in the sky at different times of the year. At that time, everything about the Moon was learned by watching it c______72______ in the sky.
When scientists could use telescopes to study the moon more closely, their ideas began to change. They could see the moon was made of r______73______. Most scientists thought moon rocks would be different from those on the Earth. This was because they believed the moon had once been a planet that had been caught in the Earth’s g______74______ millions of years earlier.
In 1969, moon rocks were finally brought to the Earth and s______75______. Much to their surprise, scientists found that, except for water, the moon and the earth were made of the s______76______ things. Once again new ideas were needed for this new information.
After years of study, most scientists now think that the moon was once p______78______ of the earth. They believe very early in its history, maybe 4 billion years ago, something about the size of Mars h______79______ the earth. This sent billions of rocks into space around our p______80______. These rocks slowly joined together and after many years became the Moon.
In the future, even thought our ideas about the moon may change again, we will still be interested in it.

However, not all of them fully agree with this new finding. The model researchers used has been called into question, especially as it relates to measurements(测量) of faraway high-mass (高质量的)galaxies which have been studied by others searching for dark matter.
Well have to wait and see how this all goes, but the results are certainly interesting and will no doubt further the conversation about where the universe's dark mater lies.

What will astronauts eat when a space trip takes years “Lots of fresh vegetables,” says Br. Janet Williams, whose team have spent the last 10 years learning how to grow plants in a space station. And it’s a good thing that she has already started her work, because space gardening can be really hard.
As usual, astronaut George White looked into the closed plant room. He had planted Dr. Williams’s quick-growing seedlings in it, but none of the stems were showing. He opened the room to check and found the problem. The stems weren’t growing upward and the roots weren't growing downward. On Earth, gravity（重力）helps a plant’s stems and roots to find “up”and “down”. However, in the space station, there was almost no gravity.
Dr. Williams suggested a solution: give the plants more light, as plants also use sunlight to find their way. And it worked. When the plants had more light, the stems turned up and the roots went down.
Now Dr. Williams was free to worry about the next problem:Would her baby plants live to flower Can we grow food on a space journey
Many plants died in the space station. Dr. Williams thought she knew why: the space plants were hungry for air. Plants live by taking up CO2 from the air. Since a plant uses it up in the air around, the plant needs moving air to bring more CO2 close to its surface! On Earth, the air is always moving. Gravity pulls down cold air, and warm air rises. And with these air movements, plants get enough CO2.
Many earlier experiments with plants in space had used closed rooms.Dr. Williams tried a new greenhouse that had a fan to keep the air move. The plants loved it. They flowered and even produced more seeds. Using Dr. William’s method, astronaut George completed the first seed-to-seed experiment in space, and moved one plant closer to a garden in space.
“And this.” says Dr. Williams. “is good news for long-term space travel.”
36. Why have Dr Williams’s team tried to grow plants in space
A. To produce fresh air for astronauts.
B.To help astronauts relax themselves.
C.To provide food for long space journeys.
D.To make the space garden more beautiful.
37. How did light help solve the problem mentioned in Paragraph 3
A. It caused the gravity to change.
B. It encouraged the plants grow faster.
C. It helped the plants to grow in the right direction.
D. It showed the astronauts where to plant vegetables.
38. Why did many plants die in the space station
A. The light was too strong. B. There was too much CO2.
C. There was not enough room to grow. D. The air condition was not good enough.
39. The underlined word “it” in Paragraph 7 refers to
A. the moving air B. the closed room C. the space journey D. the space garden
40. What can we learn about Dr. Williams’s team from the passage
A. They mainly live on fresh vegetables.
B. They have successfully built a space garden.
C. They invented a special fan for their greenhouse.
D. They have worked on space gardening for many years.

For centuries, human beings have dreamed of traveling into space, orbiting（围绕…运行）our little blue planet, and enjoying amazing views of sunrises and sunsets. And soon, it seems that our dream will finally come true, as a US tech company Orion Span announced that it planned to start the first hotel in space and it will be ready to welcome guests from the Earth.
The space hotel, Aurora Station, will orbit 320 kilometers above Earth.circling it every one and a half hours.It can hold two crew members（工作人员）and four guests.The crew members will likely be former NASA astronauts who worked on the International Space Station.However,each guest must pay at least $9.5 million (60 million yuan) for a 12-day stay at the hotel.
Once aboard the Aurora Station, guests will find many exciting things to do. According to Orion Span, guests can enjoy the excitement of zero-gravity as they fly throughout the space hotel. They can watch 16 sunrises and sunsets every day and view the northern and southern auroras（极光）through the windows. They can take part in research experiments like growing food, and even take it home as a souvenir. And there’s a possibility that they can contact their families and friends on Earth through a high-speed Internet connection.
But most importantly, the trip will offer areal sense of what it's like to live in space. “The premise（前提）of Aurora Station is for guests to live, feel, and breathe what it’s like to be an astronaut,” Frank Bunger, CEO of Orion Span, told the Robb Report. “The food and drinks are freeze-dried products. It’s not going to be five-star dining ... Fire and gas don’t work the same way in space as they do on Earth."To better prepare guests for space-travel, the company will offer a three-month training program that helps guests understand basic spaceflight, orbital mechanics（轨道力学）and life in the pressurize environment of space.
Some may have doubts about he project, but the company even has plans to turn part of Aurora Station into private flats. “Future Aurora owners can live in, visit, or sublease（转租）their space flat,” Bunger said. “This is an exciting frontier（待开发的领域）and Orion Span is proud to pave the way.

We have always been interested in the moon. 2000 years ago, people already knew it m______71______ around the Earth and where it would be in the sky at different times of the year. At that time, everything about the Moon was learned by watching it c______72______ in the sky.
When scientists could use telescopes to study the moon more closely, their ideas began to change. They could see the moon was made of r______73______. Most scientists thought moon rocks would be different from those on the Earth. This was because they believed the moon had once been a planet that had been caught in the Earth’s g______74______ millions of years earlier.
In 1969, moon rocks were finally brought to the Earth and s______75______. Much to their surprise, scientists found that, except for water, the moon and the earth were made of the s______76______ things. Once again new ideas were needed for this new information.
After years of study, most scientists now think that the moon was once p______78______ of the earth. They believe very early in its history, maybe 4 billion years ago, something about the size of Mars h______79______ the earth. This sent billions of rocks into space around our p______80______. These rocks slowly joined together and after many years became the Moon.
In the future, even thought our ideas about the moon may change again, we will still be interested in it.
