Before astronauts can go into space, they have to have the right suit. That’s why NASA(美国国家航天和航空局)scientists are developing a new kind of space suit——lighter and more flexible than before. These new space suits will have lots of mobility(灵活性) for the astronauts, but will not need much maintenance. NASA wants the suits to include new technology that can help astronauts be safe in outer space.
Right now, the American space suit weighs about 275 pounds and is big and massive. But the suit is also easy to work in for long periods of time. The Russian space suit is less complicated, but is used only a few times and then gets thrown away.
“Finding the right balance is always going to be a challenge,” said a long-time astronaut Jeff Williams. Williams has worn both types of suits. Space suits protect astronauts from both extreme heat and freezing temperatures. They carry life-packs with oxygen for the astronauts. They also shield astronauts from radiation, or particles that send out harmful rays.
Scientists are using computers to design the new suits. This allows them to change the design again and again, and to even test the design out before actually making anything. “There’s a lot more capable tools and technology to get the job done——a lot more knowledge, as well,” said Joe Kosmo. Kosmo helped design, develop, and test suits during the Mercury, Gemini, Apollo, Skylab, and shuttle periods.
These new space suits will be much lighter and use a new kind of complex material. They also will have a smaller life support backpack, thanks to tiny electronics. NASA hopes to have the first prototypes(原型) in development by 2010 and certify(证明) the suit by 2012. This will be in time for the launch of the Orion spaceship in 2014.
1. What characteristic does the new space suit have?
A. The new space suit will need much maintenance.
B. The new space suit will be heavier than before.
C. The new space suit will have less mobility than before.
D. The new suit will use new technology to help astronauts be safe in outer space.
2.What’s the disadvantage of the Russian space suit?
A. The Russian space suit is big and massive.
B. The Russian space suit is much complicated.
C. The Russian space suit is merely used a few times.
D. The Russian space suit is easy to work in for long periods of time.
3.The underlined word “shield” in the third paragraph might mean_______.
A. harm B. protect C. help D. warn
4.Why can scientists test the design out before actually making the new space suits?
A. Because designing the new space suit is not a complex task.
B. Because computers are being used to help scientists design the new space suits.
C. Because it needs little knowledge to design the new space suits.
D. Because the scientists only change the old space suits a little and make them into the new ones.
5.How long will it take scientists to put the new space suits from prototypes into the first practical use?
A. Two years. B. Three years. C. Four years. D. Six years.

Astronauts aboard the International Space Station (ISS) recently tested an oven they used to bake five chocolate chip cookies. We now know the results of that experiment: the cookies took a lot longer to bake in space than on Earth. The cookies that came out best required two hours of baking time inside the International Space Station. The baking time for cookies on Earth is generally only about 20 minutes.
The cookies returned to Earth earlier this month aboard a SpaceX-built spacecraft that splashed down in the Pacific Ocean. The cookies are the first food baked in space from raw food materials. They remain frozen in a laboratory in Houston, Texas. The American company Nanoracks designed and built the cookie oven. Hilton DoubleTree hotels supplied the cookie dough.
The makers of the oven did expect some difference in the baking time in space, but they were surprised that that difference was so large. "There's still a lot to look into to figure out really what's driving that difference, but definitely a cool result," said Mary Murphy. She is with the company Nanoracks, which is based in Texas. Murphy said the baking results will continue to be examined in order to better understand why space baking took so much longer. In addition, researchers will study the effectiveness of the baking tray, which was designed to work in microgravity conditions.
The five chocolate chip cookies were frozen when they were sent to space. Each had to be baked separately in the oven. Italian astronaut Luca Parmitano took charge of the baking experiment in December. He reported that the first cookie stayed in the oven for 25 minutes at 149 degrees Celsius. When it came out of the oven, it was seriously under-baked. For the next two cookies, Parmitano more than doubled the baking time. Those cookies came out better, but were still under-baked. The fourth cookie stayed in the oven for two hours, after which Parmitano was able to report success. "I can't tell you whether it's cooked all the way or not, but it certainly doesn't look like cookie dough anymore," he reported to controllers back on Earth. For the fifth cookie, Parmitano turned the oven temperature up to 163 degrees Celsius and baked it for 130 minutes. This time, he reported the best baking results.
No one has tasted the space-traveling cookies just yet. Organizers of the experiment say additional testing will need be carried out to determine whether they are safe to eat.
1.How long do it takes to bake cookies in ISS?
A.About 20 minutes. B.25 minutes.
C.About an hour. D.2 hours.
2.What is the oven maker's attitude towards the large difference?
A.Critical. B.Amazed.
C.Indifferent D.Worried
3.What can we infer from the fourth paragraph?
A.The baking experiments ended up in a success.
B.Each of the five cookies was cooked in different time.
C.The more time, the better baking results.
D.The five cookies were frozen after baking.
4.What can be concluded in the passage?
A.The space-traveling cookies are safe for astronauts to eat.
B.Cookies on Earth are the same as the space-traveling cookies.
C.More tests will be taken for the space-traveling cookies.
D.The five cookies ended up in the Pacific Ocean.

Humans have launched themselves into the outer space. They’ve landed on the moon. They’ve built habitable space stations that orbit the Earth. The next giant leap for mankind is to reach another planet – specifically, Mars.
The problem is that it’s no easy task. The planet is 586 times further away from the Earth than the moon, and it’ll take around 180 to 220 days to reach Mars, depending on where each planet is in its orbit. Such long periods in space have suggested many potential health problems, including hormonal changes, skin conditions, and muscle and bone deterioration (损耗).
Here’s where some furry friends come in. A wide range of animals have been in space, from fruit flies and spiders to cats, and dogs. Such experiments began as far back as the late 1940s in first tests to see if living things could withstand the extreme g-force (重力) of a rocket launch.
Mice continue to play a very important part in space experiments, mainly because the animals make excellent test subjects. They’re small, which makes them inexpensive and easy to care for. In addition, their size and short life span make it possible to do the equivalent of several human years of tests in a much shorter time. Finally, because mice are mammals, they share many common characteristics with humans in terms of genetics, biology and behavior.
Astromice have hit the headlines recently, as a team of scientists led by Betty Nusgens, professor of biology at the University of Liege in Belgium, found that the mice suffered a 15 percent thinning of their skin after 91 days aboard the International Space Station (ISS).
This experiment was part of a wider NASA mission (任务) called the Mice Drawer System (MDS). The Italian Space Agency developed the facility, which allows six mice to be housed, monitored, and automatically fed and watered aboard the ISS, among which three survived during the mission.
The mice have participated in 20 separate experiments, to study such effects as osteoporosis (骨质疏松症), anemia (贫血) and heart health.
Results for the 20 experiments are coming in gradually. But it’s clear that mice continue to play an important role in the ongoing quest to conquer the final frontier.
1.We can infer from Paragraphs 2-3 that ______.
A. Mars is the farthest planet away from Earth discovered so far
B. the journey to Mars could put humans’ health at risk
C. it was in the late 1940s that animals were first sent to the ISS
D. animals that have been sent into space have mostly survived
2.The underlined word “withstand” in Para.3 means _________.
A.set up B. hold up
C. work out D. come across
3.According to Betty Nusgens and her team, the mice aboard the ISS ______.
A. suffered the loss of part of their skin
B. all survived for the duration of the mission
C. were fed and watered by the astronauts
D. participated in 20 experiments that made great breakthroughs
4. The main purpose of the article is to _____.
A. describe the role mice play in scientific research
B. report on the results of the Mice Drawer System
C. analyze how mice could pave the way to Mars
D. change people’s traditional attitudes toward mice
