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 ballet（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 your 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 you’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 of 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 astronaut healthy. NASA is worried about two things: recovery time once 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 Theresa Loe is doing proves that a large farm isn’t a prerequisite for a modern grow-your-own lifestyle. On a mere 1/10 of an acre in Los Angeles, Loe and her family grow, can (装罐) and preserve much of the food they consume.
Loe is a master food preserver, gardener and canning expert. She also operates a website, where she shares her tips and recipes, with the goal of demonstrating that everyone has the ability to control what’s on their plate.
Loe initially went to school to become an engineer, but she quickly learned that her enthusiasm was mainly about growing and preparing her own food. “ got into cooking my own food and started growing my own herbs(香草)and foods for that fresh flavor,” she said. Engineer by day, Loe learned cooking at night school. She ultimately purchased a small piece of land with her husband and began growing their own foods.
“I teach people how to live farm-fresh without a farm,” Loe said. Through her website Loe emphasizes that ‘‘anybody can do this anywhere.” Got an apartment with a balcony (阳台)? Plant some herbs. A window? Perfect spot for growing. Start with herbs, she recommends, because “they’re very forgiving.” Just a little of the herbs “can take your regular cooking to a whole new level,” she added. “I think it’s a great place to start.” Then? Try growing something from a seed, she said, like a tomato or some tea.
Canning is a natural extension of the planting she does. With every planted food, Loe noted, there’s a moment when it’s bursting with its absolute peak flavor. “I try and keep it in a time capsule in a canning jar,” Loe said. “Canning for me is about knowing what’s in your food, knowing where it comes from.”
In addition to being more in touch with the food she’s eating, another joy comes from passing this knowledge and this desire for good food to her children: “Influencing them and telling them your opinion on not only being careful what we eat but understanding the bigger picture,” she said, “that if we don’t take care of the earth, no one will.”
1.The underlined word “prerequisite” (Para. 1) is closest in meaning to“ ”.
A. recipe B. substitute
C. requirement D. challenge
2.Why does Loe suggest starting with herbs?
A. They are used daily. B. They are easy to grow.
C. They can grow very tall. D. They can be eaten uncooked.
3.According to Loe, what is the benefit of canning her planted foods?
A. It can preserve their best flavor. B. It can promote her online sales.
C. It can better her cooking skills. D. It can improve their nutrition.
4.What is the “the bigger picture” (Para. 6) that Loe wishes her children to understand?
A. The knowledge about good food. B. The way to live a grow-our-own life.
C. The joy of getting in touch with foods. D. The responsibility to protect our earth

Science has a lot of uses. It can uncover laws of nature, cure diseases, make bombs, and help bridges to stand up. Indeed science is so good at what it does that there’s always a temptation(诱惑) to drag it into problems where it may not be helpful. David Brooks, author of The Social Animal: The Hidden Sources of Love, Character,and Achievement, appears to be the latest in a long line of writers who have failed to resist the temptation.
Brooks gained fame for several books. His latest book The Social Animal, however, is more ambitious and serious than his earlier books. It is an attempt to deal with a set of weighty topics. The book focuses on big questions: What has science revealed about human nature? What are the sources of character? And why are some people happy and successful while others aren’t?
To answer these questions, Brooks surveys a wide range of disciplines（学科）. Considering this, you might expect the book to be a dry recitation of facts. But Brooks has structured his book in an unorthodox(非常规的), and perhaps unfortunate, way. Instead of introducing scientific theories, he tells a story, within which he tries to make his points, perhaps in order to keep the reader’s attention.So as Harold and Erica, the hero and heroine in his story, live through childhood, we hear about the science of child development and as they begin to date we hear about the theory of sexual attraction. Brooks carries this through to the death of one of his characters.
On the whole,Brooks’ story is acceptable if uninspired. As one would expect, his writing is mostly clear and, to be fair, some chapters stand out above the rest. I enjoyed, for instance, the chapter in which Harold discovers how to think on his own. While Harold and Erica are certainly not strong or memorable characters, the more serious problems with The Social Animal lie elsewhere. These problems partly involve Brooks’ attempt to translate his tale into science.
1.The author mentions the functions of science at the beginning of the passage to__________.
A.illustrate where science can be applied
B.demonstrate the value of Brooks’ new book
C.remind the reader of the importance of science
D.explain why many writers use science in their works
2.According to the author, which of the following could be a strength of the book?
A.Its strong basis.
B.Its convincing points.
C.Its clear writing.
D.Its memorable characters.
3.What is the author’s general attitude towards the book?
A.Contradictory.
B.Supportive.
C.Cautious.
D.Critical.
4.What is the author likely to write about after the last paragraph?
A.Problems with the book.
B.Brooks’s life experience.
C.Death of the characters.
D.Brooks’s translation skills.
