The oddness of life in space never quite goes away. Here are some examples.
First consider something as simple as sleep. Its position presents its own challenges. The main question is whether you want your arms inside or outside the sleeping bag. If you leave your arms out, they float free in zero gravity, often giving a sleeping astronaut the look of a funny balled （芭蕾）dancer. "I'm an inside guy," Mike Hopkins says, who returned from a six-month tour on the International Space Station. "I like to be wrapped up."
On the station, the ordinary becomes strange. The exercise bike for the American astronauts has no handlebars. It also has no seat. With no gravity, it's just as easy to pedal violently. You can watch a movie while you pedal by floating a microcomputer anywhere you want. But station residents have to be careful about staying in one place too long. Without gravity to help circulate air, the carbon dioxide you exhale (呼气) has a tendency to form an invisible （隐形的）cloud around you head. You can end up with what astronauts call a carbon-dioxide headache.
Leroy Chiao, 54, an American retired astronaut after four flights, describes what happens even before you float out of your seat,"Your inner ear thinks your're falling . Meanwhile your eyes are telling you you're standing straight. That can be annoying-that's why some people feel sick." Within a couple days -truly terrible days for some -astronauts' brains learn to ignore the panicky signals from the inner ear, and space sickness disappears.
Space travel can be so delightful but at the same time invisibly dangerous. For instance, astronauts lose bone mass. That's why exercise is considered so vital that National Aeronautics and Space Administration (NASA) puts it right on the workday schedule. The focus on fitness is as much about science and the future as it is about keeping any individual astronauts return home, and, more importantly, how to maintain strength and fitness for the two and a half years or more that it would take to make a round-trip to Mars.
What is the major challenge to astronauts when they sleep in space?
The astronauts will suffer from a carbon-dioxide headache when _____.
Some astronauts feel sick on the station during the first few days because _____.
One of the NASA's major concerns about astronauts is _____.
New findings show that musical training affects（影响）the structure and function of different brain areas, how those areas communicate during the creation of music, and how the brain interprets and combines sensory(感官) information. The findings were presented at Neuroscience 2013, the annual meeting of the Society for Neuroscience and the world’s largest source of emerging news about brain science and health. These views suggest potential new roles for musical training including training plasticity（可塑性）in the brain, offering an alternative tool in education, and treating a range of learning disabilities.
Today’s new findings show that long-term high level musical training has a broader effect. Researchers found that musicians have a better ability to combine sensory information from hearing, touch, and sight. The age at which musical training begins influenced brain structure and its function. Beginning training before the age of seven has the greatest effect.
Even older adults who took music lessons as children but haven’t actively played an instrument in decades have a faster brain response(反应) to a speech sound than those who never played an instrument, according to a study appearing November 6 in the Journal of Neuroscience. The finding suggests early musical training has a lasting, positive effect on how the brain deals with sound.
“Playing a musical instrument is a multi-sensory and motive experience that creates emotions and movements—from finger tapping to dancing — and engages pleasure and reward systems in the brain. It has the potential to affect brain function and structure when done over a long period of time,” said Gottfried Schlaug, MD, PhD, of Harvard Medical School, press conference speaker, also an expert on music.
“As today’s findings show, musical training brings about new processes within the brain, at different stages of life, and with a range of effects on creativity, cognition(认知), and learning,” he added. From the first paragraph, we can see musical training can .
| A．affect one’s communication with others |

When I was a kid, I was close to my dad, but as I grew older, my dad and I grew further apart. We always had totally different opinions. He thought that college was a waste of time, but for me it was important to finish college. He wanted me to work my way to the top as he had done in his field, but I wanted a different life. There was a time when we did not talk with each other.
A few months ago, I heard that my 84-year-old dad was in poor health. When he called and asked whether I could move from Colorado back to Tennessee to help him, I knew he was seriously ill. I am his only child and so it was time to meet my father’s requirement.
Two weeks after moving back, we bought a boat and started fishing again. Fishing was one of the few things that we did while I was young and that we both enjoyed. It is strange but true that as we are fishing we are able to put things that have kept us apart for so many years behind us. We are able to talk about things that we have never talked about before. Fishing has been healing the old wounds that have kept us apart
It is not important how many fish we catch. It is about enjoying the relationship that we have not had for years. I’m 62 and he is 84. When we are on the lake fishing, it is like two kids enjoying life. It is far better to find a way to put the unhappy past behind.

Since we are social beings, the quality of our lives depends in large measure on our interpersonal relationships. One strength of the human conditions is our possibility to give and receive support from one another under stressful(有压力的) conditions. Social support makes up of the exchange of resources among people based on their interpersonal ties. Those of us with strong support systems appear better able to deal with major life changes and daily problems. People with strong social ties live longer and have better health than those without such ties. Studies over types of illnesses, from depression to heart disease, show that the presence of social support helps people defend themselves against illness, and the absence of such support makes poor health more likely.
Social support cushions stress in a number of ways. First, friends, relatives and co-workers may let us know that they value us. Our self-respect is strengthened when we feel accepted by others in spite of our faults and difficulties. Second, other people often provide us with informational support. They help us to define and understand our problems and find solutions to them. Third, we typically find social companionship supportive. Taking part in free-time activities with others helps us to meet our social needs while at the same time distracting (转移注意力) us from our worries and troubles. Finally, other people may give us instrumental support — money aid, material resources, and needed services — that reduces stress by helping us resolve and deal with our problems.Interpersonal relationships are important because they can _______.
| A．make people live more easily |
| B．smooth away daily problems |

Alsten Chase has written a book about Yellowstone National Park. He is worried about the damage the fires can do to the park. He is also concerned(关心) about the park rules.
These rules say that nature should decide what happens to the park. Alsten also writes that the elk herd(马鹿群) has grown too big. The elks walk on the riverbanks. They eat the new grass and roots of baby trees. The beavers (河狸) need the trees to build dams.
The dams raise the water levels. Higher water levels put more water into the soil. Moist soil helps plants grow faster. The plants offer homes and food to other animals.
Chase thinks that the park rules would work only in a park with natural settings. He believes that Yellowstone has had an artificial setting for a long time. The native people left. The wolves were taken away and other animals were removed．The areas of land were fenced off and other animals added．He thinks the park rules that let herds grow too big and the fires burn are hurting the nature of the park.
The park manager thinks the rules are good and that the park will be fine. Chase thinks the way the people run the park should be changed.In Chase’s opinion, too many elks in the park will ___.
| A．cause great fires | B．break the balance of nature |
| C．destroy the dams | D．do no damage at all |
Chase thinks that the park is ____.
| A．no longer in a natural state | B．still in a natural stat |
| C．well protected | D．well managed |
