1、Life in space will certainly take some getting used to! But the space station has been designedto keep the astronauts as comfortable as possiblethe modules（舱） are roomy，bright，and kept at a constant 21C. Its important the crew members are comfortable because theyll be busy aboard the station. In a t

2、ypical workday，crew members will spend 14 hours working and exercising, 1.5 hours preparing and eating meals，and 8.5 hours sleeping. Here are some other fun facts about life aboard the station：Food Come mealtime, astronauts will have a special dining kitchen. Space food just keeps getting betterand

3、more like food we enjoy here on Earth. In early space missions, astronauts could eat only freeze-dried food that didnt require any preparation. But the space station is equipped with water, microwave ovens, and refrigerators, allowing the folks on board to eat more “normal” types of food, including

4、fruit, vegetables, and ice cream!Sleep Each crew member has a private room. With no gravity, theyll need to tie themselves to their beds, or they will float away！That might sound like a strange way to sleep, but astronauts from past space missions report that sleeping in space is actually pretty gre

5、at!Exercise You might not think it, but exercise is even more important on the station than it is on Earth. There is not much gravity in space. Astronauts dont stand up, sit down or walk in space, so their muscles and bones dont have to work muchand this muscle and bone loss can be dangerous back on

6、 Earth. To fight this, astronauts on the station will exercise on bikes, rowing machines, and other equipment about two hours every day.Clothing Astronauts will have to wear special space suits while traveling aboard the U.S. shuttle or Russian rockets. But once theyre safe inside the space station,

7、 crew members can wear regular clothing. Of course, a specially designed pressurized space suit is required for space walks. It has to bear flying pieces and protect the astronauts from dramatic temperature changes. It can range from -84 C in the shadow of the station to 121C in the hot sun.Personal

8、 CleanlinessSimple tasks like brushing your teeth can be challenging in a weightless environment. A little water doesnt flow in a stream. Astronauts will use a freshwater hose（软管） to take showers, shampoo，and wash offthen a second vacuum hose to suction（吸） off the dirty water. And how do you go to t

9、he bathroom in space? With a special “air toilet” that uses flowing air instead of water to get rid of waste.21.

12、othing”? A. The temperature is quite different in different places in space. B. Astronauts wear pressurized space suits just to keep warm. C. Astronauts must wear special space suits all the time in space. D. Astronauts can wear regular clothing for space walks now.B Its 3 oclock and youve been hard

13、 at work. As you sit at your desk, a strong desire for chocolate overcomes you. You try to busy yourself to make it go away. But it doesnt. Here is another situation. Perhaps you are not feeling well. The only thing you want to eat is a big bowl of chicken soup, like your mom used to make when you w

14、ere sick as a child. Food cravings are a strong desire for a specific type of food. And they are normal.Scientists at the website How Stuff Works compare hunger and cravings this way. Hunger is a fairly simple connection between the stomach and the brain. They even call it simply “stomach hunger.” W

15、hen our stomachs burn up all of the food we have eaten, a hormone （荷尔蒙） sends a message to one part of the brain for more food, which regulates our most basic body functions such as thirst, hunger and sleep. The brain then produces a chemical to start the appetite and you eat. Hunger is a function o

16、f survival.A craving is more complex. It activates （使活跃） brain areas related to emotion, memory and reward. These are the same areas of the brain activated during drug-craving studies. Because of this, some scientists call food cravings “mind hunger.” People often crave foods that are high in fat an

17、d sugar. Foods that are high in fat or high in sugar produce chemicals in the brain. These chemicals give us feelings of pleasure. In a 2007 study, researchers at Cambridge University found that “dieting or restricted eating generally increases the possibility of food craving.” So, the more you deny

18、 yourself a food that you want, the more you may crave it. However, fasting is a bit different. They found that eating no food at all for a short period of time lessened food cravings. So, the next time you crave something very special, know that your brain may be more to blame than your stomach. 25

19、. The author describes two situations in the first paragraph to _. A.remind readers of their own special food. B.deepen the understanding of hunger.C.report the discovery of craving study.D. introduce the topic of the whole passage.26. What do we learn about food craving?It shows food is linked to f

B.The increase of food desire.The refusal of fat and sugar. D.The disappearance of appetite.28. In which colum

21、n of a newspaper can you see this passage? Education B.Entertainment Science D.Economy C NASA might be famous for sending rockets up to space quickly. But it will be more famous for making your next holiday come more quickly. The space agency is working on a new plane, which could solve the problems

22、 of supersonic（超音速的） flight and vastly increase the speed of journeys abroad. If successful, the plane would be able to fly between New York and London in just three hours. And it would reduce the time spent flying other journeys by a half, since it could be used more broadly. Until now, the problem

23、 with such planes has been the sonic boom（声爆）, made famous by the original Concorde（协和客机）. That happens when a plane reaches supersonic speeds. It is a thunderous noise that upsets people on the ground disturbing animals and even causing physical problems to materials and houses underneath. It was t

24、hat effect that led Congress to ban such planes from being used over the US land, a decision that in turn was responsible for Concordes failing to be commercially used. In view of the problem, the space agency has developed a new technology and tried it out in wind tunnels, and now believes that it

25、could be put to commercial use. That plane will fly as high as 55,000 feetfar higher than normal planesand make a sound of only 60 decibels. Thats far less than 90 decibels thrown out by normal planes, and is roughly in line with a car on the motorway or a busy restaurant. “As long as we can get end

26、orsement from the general public, the plane will probably be something thats acceptable,” said Peter Coen, project manager for NASAs commercial supersonic research team, in a new Bloomberg report. “If we get approved, we will have the full-sized version of the plane tried out and the plane will be p

27、ut into use.” 29. Why does the author mention Concorde?To suggest the rapid development of planes in the USA.To make us know the negative effect of the sonic booms better.To introduce how a commercial plane is designed.To show us that Concorde finally failed to be commercially used.30. What is the f

28、ourth paragraph mainly about?The basic data of the new plane.The working principle of the new plane.The problems of the new plane.The potential market of the new plane.31. What does the underlined word “endorsement” in paragraph 5 mean?response B.commitmentinvestment D.agreement32. Why does the auth

29、or write the passage?Because he wants to inform people of NASAs new plane.Because he wants to prove the disadvantages of supersonic flight. C.Because he wants to explain why speed matters in supersonic flight. D.Because he wants to clarify some misunderstandings about commercial planes.DOf all natur

30、al disasters, forest fires are often considered the most frightening. Moving at lightning speed, huge walls of flames can burn acres of land in just a few minutes. And although technology, including the use of fire-retardant chemicals, has greatly helped the fight against forest fires, they still do

31、 great damage. According to the National Interagency Fire Center, the fire season last year was the worst on record in terms of the number of fires and acres burned. There were 96. 385 fires and 9.873429 acres affected by fire in a year that was 125% more destructive than the10-year average. These fires cost the federal government $1.5 billion to fight, and this figure does not include the mon
