BEING an astronaut sounds cool, doesn't it? In space, they get to do some pretty amazing things, like floating in zero gravity(重力).
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, according to The Atlantic(大西洋月刊) in January. Without gravity, tears don't flow(流动) down 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(粘) to your eyes.
In May 2011, astronaut Andrew Feustel experienced this during one of his spacewalks. "Tears," he said, "don't fall off of your eyes...They just kind of stay there."
Besides making your vision(视线)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 stinging(刺痛) 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(除去) the tears. Feustel chose to rub his eyes against his helmet to wipe(擦) the tears away. Another choice is to just wait-"When the tears get big enough they simply break free of the eyes 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 (打嗝), 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.
Therefore, perhaps it's only space explorers who can honestly say: "Gravity, you're the best."
1.From Paragraphs 2 and 3 , we can know that_______.
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.The underlined phrase "take them for granted" in paragraph 7 means _______.
A.find them important
B.consider them useless
C.need them during an emergency
D.fail to notice their presence(存在)
4.The second-to-last paragraph (paragraph 7) is mainly about_______.
A.suggestions of 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 human can't do without gravity

BEING an astronaut sounds cool, doesn’t it? In space, they get to do some pretty amazing things, like floating(漂浮) in zero gravity(重力).

Astronauts, people who fly into space, need special training. First they go to Houston, Texas. That is the home of the Johnson Space Centre. There they are tested to see how strong and smart they are.
One of the first tests is for the heart. The people walk or run, then the space doctors see how fast their hearts are beating.
Another important test is performed. In this test the person must curl(蜷曲)his body up in a ball. When he is in that position, he is put into a round cloth bag. The doctors give him no idea how long he will have to stay in the bag. If a spaceship broke down in space, the astronauts would get into bags like this. Then they would have to wait and curl up in darkness, until help could arrive. You can see that an astronaut must not be afraid of tight space or darkness.
After the tests, only the best people are chosen to start astronaut training in a training centre. The astronauts in training learn many other things. They learn how to jump out of a moving airplane. They learn to how to blow up a lifeboat and get into it while they are in the ocean. The astronauts also have to learn how to get lifted out of the ocean by helicopter(直升机). That may look fun, but it can be dangerous.
After they finish training, the astronauts continue to work. They stay in good shape by running and doing exercise. They read about their special jobs. In that way they can learn new facts about space travel.
Then the big day comes. The astronaut is told to go to work on a flight into space. The crew members(全体船员)get to know each other first. Then they can learn which job each will do.
1.The astronauts don’t know how long they will stay in the bag in the test because ________________.
A. the doctors need to know how strong they are
B. the astronauts need to show how smart they are
C. good astronauts mustn’t be afraid of darkness or tight space
D. nobody knows when help will come if the spaceship breaks down
2.The astronauts don’t learn how to ________________ in the training centre.
A. walk or run in space B. jump out of the moving plane
C. blow up a lifeboat D. get lifted out of water by helicopter
3.Which is the correct order according to the passage?
a. Doctors do tests on the astronauts.
b. The astronauts go to the Space Centre.
c. The astronauts learn new facts about space travel.
d. The best people are chosen for training.
e. The astronauts go to work on a flight into space.
A. a, b, c, d, e B. d, a, e, b, c C. b, a, d, c, e D. c, d, e, b, a
4.Which of the following is NOT true?
A. After the tests, only the best people are chosen to start astronaut training in a training centre.
B. The crew members get to know each other after the tests.
C. One of the first tests is for the heart.
D. An astronaut must not be afraid of tight space or darkness.

All About Astronauts
Part 1. Special Mission
Astronauts travel into space. The astronauts work in teams to do missions in space. One team of U.S. astronauts had a very special mission to fly from Earth to the moon in July of 1969. People all over the world watched on TV as this team arrived at the moon. The astronaut Neil Armstrong, the captain of the team, became the first person to walk on the moon. After that, other astronauts went on missions to the moon. They collected samples of moon rocks and moon dirt, and they brought them back to Earth.
Part 2. Astronauts' Training
It takes lot of study and hard work to become a real astronaut. Astronauts take special training to learn more about space flight. They also learn about rockets, stars, and planets. They learn about their missions, too. Before their mission, Neil Armstrong and his team studied the moon and the rocks they might find. Some of them are pilots. They need to know how to fly a spacecraft. They use special models to practice flying the spacecraft. They also learn how to wear a space suit. It's usually big and heavy. An astronaut learns how to move in the suit by going into a pool. Moving around underwater feels like moving around in space.
Part 3. __________________
On the moon and out in space, there is little or no gravity(重力). When the spacecraft flies into space, the things inside float(漂浮)around. Astronauts eat food from special packages. The packages are tied to a tray, so the food doesn't fly away. When astronauts want to sleep or exercise, they wear a special strap which can hold them in place.
Sometimes astronauts need to do work outside the spacecraft. Temperatures in space can be very hot or very cold. That's why they must put on their space suits. Furthermore, there is no air in space, the suit can help an astronaut breathe.
1.In 1969, the space mission was very special because ________.
A.people could watch the team on TV
B.it was the first time that people had flied to the moon
C.Neil Armstrong was the captain
D.They brought back something special
2.During training, astronauts should learn the following things EXCEPT ________.
A.flying a spacecraft B.wearing a space suit
C.their own missions. D.special Models
3.If an astronaut wants to try his new space suit, he'd better do it in ________.
A.a spacecraft B.space C.missions D.water
4.The underlined word “strap” is a kind of special equipment likes a ________.
A.package B.space suit C.seat belt D.tray
5.The best title for Part 3. is ________.
A.No Gravity B.Special Food C.Space Suits D.Life in Space
6.The passage is probably from a ________ magazine.

Eating in space is different from eating on the earth. The food that astronauts carry with them does not look like the food you eat.
Some food is carried in closed bags. It is cooked and frozen before the astronauts get it. All the water is removed from the food. In the spaceship, the astronaut puts the water back. He “shoots” hot or cold water into the food bag with a special gun. He eats the food through a small hole in the bag.
Other foods come in bite sizes. The astronaut puts a whole piece in his mouth at once. There can be no crumbs. Crumbs would float around the spaceship and get in the way. Meat and cakes often come in bite-size pieces.
Astronauts cannot drink water from open cups. The water would float in drops in the spaceship. The water is put in the special gun. The astronaut shoots the water into his mouth.
1.Some food carried in the closed bags by astronauts is ________.
A. cooked and frozen B. full of water C. raw
2.Astronauts can’t drink from open cups because__________.
A. the water would float in drops around the spaceship
B. the water would spill all over their foods
C. crumbs would float in the cups
3.The main idea of the passage is that __________.
A. astronauts cannot eat or drink in a spaceship until they come back to the earth
B. eating and drinking in the spaceship is a special problem
C. there is more food and water in space than on the earth
