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 (損耗).
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 (任務) 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 (骨質疏松癥), anemia (貧血) 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.

A. Mars is the farthest planet away from Earth discovered so far
B. animals that have been sent into space have mostly survived
C. it was in the late 1940s that animals were first sent to the ISS
D. the journey to Mars could put humans’ health at risk
2.The underlined word “withstand” in Para.3 means _________.
A.set up B. come across
C. work out D. hold up
3.According to Betty Nusgens and her team, the mice aboard the ISS ______.
A. all survived for the duration(期間) of the mission
B. suffered the loss of part of their skin
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 _____.

科目：高中英語 來源：2017屆安徽蚌埠二中高三上期中考試英語試卷（解析版） 題型：閱讀理解
Sandra Bullock turned 51 last month. But because she looks exactly the same as she did in Miss Congeniality, a movie filmed back in the 20th century, everyone calls her “ageless.” Bullock is just one of a number of stars in their 40s and 50s who’ve had birthdays recently but have not gotten older, unlike the rest of us in their age group. Take Halle Berry. One website put a photo of her 20 years ago next to one of the newly 49-year-old Berry and dared us to choose which was which. “This Is What 49 Looks Like,” it said. Seriously, if that’s what 49 looks like, I must be 71.
However, even a generation ago, famous faces evolved. Look at a picture of Grace Kelly at age 52 in the early 1980s. She looks like a beautiful middle-aged woman. Today she’d look old for her age.
The goal now is to prevent aging while you are still young, using all the magical nonsurgical options medicine has to offer. Eventually these techniques will become less expensive, and ordinary people my daughter’s age will have them. Already anti-aging is starting to be considered maintenance, like coloring your hair. My friends and I find ourselves openly debating techniques that we used to make fun of. Does fat-freezing work? How much time do you have to spend in the gym to keep the body of a 35-year-old after 50? It’s all so exhausting. But members of the next generation have it tougher. They’ll have to ask themselves whether they want to spend their youth trying not to get old. I’ve already seen “Sexy at 70” headlines. Will everyone be expected to go to their graves(墳墓) looking hot?
I also have to wonder what else we are slowing along with age. How do you move on if you’re working so hard to stay the same? And besides, if you’ve known the ache of watching a daughter pack up for college, you know you can’t stop the clock.
1.In the author’s eyes, Sandra Bullock ________.
A. doesn’t deserve her name
B. doesn’t look her age at all
C. behaves like a young woman
D. looks younger than Halle Berry
2.The example of Grace Kelly is given to show ________.
A. physical beauty never lasts long
B. there is no such thing as agelessness
C. people’s attitude towards aging has changed
D. stars pay too much attention to their appearance
3.Where do the author’s concerns about anti-aging techniques lie?
A. They expose people to danger.
B. They make people feel stressful
C. They are too expensive for ordinary.
D. They encourage comparisons among people.
4.What’s the purpose of the text?
A. To show the burden of youth.
B. To offer tips on how to look hot.
C. To advise people to accept aging.
D. To comment on some famous stars.
