Being an astronaut sounds cool, doesn't it?In space, they get to do some pretty amazing things, like floating in zero gravity.
However,there are also plenty of things that astronauts can't do because of their weightless environment, and that's very sad. What's worse, they can't even let their sadness show—because it's impossible to cry in zero gravity.
Of course, astronauts can still produce tears. But crying is much more difficult in space,reported The Atlantic in January. Without gravity, tears don't flow downward out of the eyes like they do here on Earth. This means that when you cry in space, your tears have nowhere to go—they just stick to your eyes.
In May 2011, astronaut Andrew Feustel experienced this during one of his spacewalks.“Tears,” he said, “don't fall off your eye... They just kind of stay there.”
Besides making your vision unclear, this can also cause physical pain. Back on Earth, tears are supposed to bring comfort to the eyes.But that's not the case in space.The space environment dries out astronauts' eyes, and when tears suddenly wet the eyes, it can cause pain rather than comfort. “My right eye is painful like crazy.” Feustel told his teammate during the walk.
Since gravity doesn't work in space, astronauts need some extra help to get rid of the tears.Feustel chose to rub his eyes against his helmet to wipe the tears away. Another choice is to just wait—“When the tears get big enough they simply break free of the eye and float around,”astronaut Ron Parise told The Atlantic.
There are lots of small things—things like crying—that we are so used to on Earth. We usually take them for granted, until they become a problem in a totally different environment,like space. There, astronauts can't talk to each other directly. They also can't eat or drink in normal ways. They can't even burp(打隔), because there is no gravity to hold the food down in their stomach. If they do burp, they just end up throwing up(呕吐) everything in their stomach,according to the UK National Space Center.
Thus, perhaps it's only space explorers who can honestly say:“Gravity, you're the best.”
1.What can we conclude from Paragraphs 2 and 3?
A.Astronauts are unable to feel sad in space.
B.Astronauts produce fewer tears in space.
C.Tears produced in space flow down more slowly.
D.Tears produced in space don't flow downward.
2.What effect do tears have on astronauts?
A.They cause physical pain.
B.They bring comfort to them.
C.They make their vision clearer.
D.They float around and cause trouble.
3.What can the astronaut do to get rid of the tears?
A.Rub his eyes against his helmet to let the tears float forward.
B.Rub his eyes by hand to let the tears float around.
C.Get the tears big enough to fall off of his eyes.
D.Get the tears big enough to break away from his eyes.
4.What's the last but one paragraph mainly about?
A.Suggestions on how astronauts can stay comfortable in space.
B.Other basic things that are difficult to do in space.
C.Why burping is impossible in space.
D.Things that humans can't do without gravity.

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.

What does an astronaut eat in space? This is a question that will puzzle many, as people rarely think of that. In the early space-travel years, astronauts ate dehydrated (脱水的) foods that were eaten through straws (吸管). In today’s space-age, the food that they eat is totally different. They eat food in the same way as people do on Earth.
Astronauts are able to prepare and eat a variety of foods in space. Some can be eaten in their natural form, like fruits, while some need to add water, like noodles. However, there are no refrigerators, so the food has to be prepared and eaten without being stored for a long time. When the astronauts are hungry, they simply eat the food by opening the food packages and with a fork, knife, and spoon.
Just like people on Earth, astronauts also eat three meals a day which include breakfast, lunch and dinner. Sometimes they also eat snacks. The US space agency NASA has found out that an astronaut’s diet reduces by about 70% on a space mission, though he has a wide range of foods to choose from like nuts, chicken, beef, seafood, and candies. Drinks in the spaceship include coffee, tea, juices, and lemonade.
Astronauts can also request a particular food that they would like to have in space. Scientists are always experimenting and trying out different space foods that can be offered to astronauts when on space missions.
1. Now astronauts eat ________ in space.
A. dehydrated (脱水的) foods B. food as people do on Earth
C. totally different D. food with a lot of water
2. The food the astronauts prepared ________ .
A. can’t be stored for a long time B. is put into refrigerators
C. can be stored for a long time D. can’t be kept in the food packages
3. In space, astronauts ________ like people on Earth.
A. only have nuts, chicken and beef B. only have lunch for a day
C. only drink coffee, tea and lemonade D. also eat three meals a day
4. What is the text mainly about?
A. Astronauts’ space life B. Astronauts’ space work
C. Astronauts’ space food D. Astronauts’ space experiments

Do women make BETTER astronauts? Russia locks an all-female crew in space simulator (太空模拟器) for eight days to find out. Six Russian women have been sent into a spaceship to begin a unique experiment testing how an all- female crew would relate to others on a trip to the Moon and back.
“It’s interesting for us to see what is special about the way a female crew communicates,” said Sergei Ponomaryov, the experiment’s leader. “it will be particularly interesting in terms of psychology,” said the institute’s director Igor Ushakov. “I’d like to wish you a lack of conflicts, even though they say that in one kitchen, two housewives find it hard to live together,” he added.
The volunteers include scientific researchers, a doctor and a psychologist. The test period simulates (模仿) a flight to the Moon and back, with the women carrying out 10 experiments covering psychology and human biology. Russia sent the first woman into space, Valentina Tereshkova, in 1963 but has fallen behind since. Last year, it sent its fourth female astronaut into space, Yelena Serova. Serava complained of a great deal of media interest in how she would wash her hair aboard the International Space Station, pointing out that male astronauts did not face the same line of questioning.
The women found themselves fielding questions at a press conference about how they would act without men or makeup for eight days, “We are very beautiful without makeup,” said participant Darya Komissarova. Her colleague Anna Kussmaul was more direct: “We are doing work. When you’re doing your work, you don’t think about men and women.” They plan to spend their 11/2 hours per day of free time watching films, reading and playing board games. Team leader Yelena Luchnitskaya said she expected the women to deal with any conflict.
1.In which column can you find this passage on a website?
A. Education. B. Entertainment.
C. Science. D. Economy.
2.What’s the purpose of the experiment?
A. To show that women can do better than men.
B. To test whether women can be good astronauts.
C. To gather information about the conditions in space.
D. To measure the distance from the earth to the moon.
3.What do we know from what Igor Ushakov said?
A. Women can not live peacefully in space at all.
B. There may be conflicts among the women astronauts.
C. The female crew will deal with each other in a new way.
D. Being in the same kitchen helps the women live together.
4.Which of the following was once sent into space?
A. Sergei Ponomarev. B. Darya Komissarova.
C. Anna Kussmaul. D. Valentina Tereshkova.
