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.

More than two thirds of the world's polar bears will be wiped out by 2050，according to a shocking new study. By then，scientists say，global warming will have melted 42 percent of the Arctic sea ice. By 2100，only a very few of these important creatures will be left.
The report has been produced by the US Geological Survey. The scientists have publicized their findings in the hope of influencing US Interior Secretary Dirk Kempthorne，who has been asked to put polar bears on the US endangered species list.
Polar bears depend on floating sea ice as a platform for hunting seals，which are their main food. Without enough ice，polar bears would be forced to go onto the land，where they are poorly skilled hunters，and would be unlikely to adapt to the life on the land in time. Experts say few little bears would survive and the stress could make many females unable to get pregnant.
The team of American and Canadian scientists spent six months studying bears，on the ground，from spotter planes and in the lab，using computer models.
Some team members fear the result is even worse for the bears than what their report says. They say the Arctic is warming faster than anywhere in the world and much faster than their computer had been forecasting. Satellite observations have showed that the ice has decreased to an all－time low.
However，not everyone in the scientific community believes that global warming is happening on such an alarming scale. Another investigation has found that polar bears are still being hunted by wealthy “sportsmen” who want their skins and heads. At least ten international companies offer bear－hunting trips.What do we know about Dirk Kempthorne according to the passage?

| B．He is a protector of animals working for the US government. |
| C．He was asked to put polar bears on the US endangered species list. |
| D．He offered to put polar bears on the endangered species list. |
Why will polar bears die out if there is not enough sea ice?
| A．Because polar bears can't catch enough food without ice. |
| B．Because polar bears eat ice when they feel thirsty. |
| C．Because polar bears will be easily found by hunters without ice. |
| D．Because most female bears are used to giving birth under ice. |
After a six－month study，some scientists fear that ________．
| A．there is something wrong with their computers |
| B．polar bears will disappear even faster than they ever expected |
| C．their computer models are not as accurate as they expected |
| D．global warming will destroy everything in the Arctic |

A teacher let her class play a game. The teacher told each child to bring a bag with some potatoes. Each potato would be given a name of a person that the child hated, so the number of potatoes in his/her bag would depend on the number of people the child hated. Some children had two potatoes, some had three and others had up to five potatoes. The teacher then told the children to carry the bag wherever they went for a week. After a week, the teacher asked, “How did you feel?” The children started complaining about the unpleasant smell coming from the rotten potatoes when they had to carry the heavy and smelly potatoes everywhere they went.
Then the teacher said,” This is the same when you carry your hate for somebody inside your heart. The smell of hate will pollute your heart and you will carry it with you wherever you go. If you cannot bear the smell of rotten potatoes for just one week, can you imagine what it is like to have the smell of hate in your heart for your lifetime?”In the game, the students should _________.

You have never seen him, but they're with you every time you fly. They record where you are going, how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to withstand (经受得住)almost any disaster makes them seem like something out of a magic book. They're known as the black box.
When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潜水艇) detected the device's homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.
In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the device（装置） was completely redesigned and moved to the back of the plane – the area least affected by impact – from its original position in the landing wells (起落架舱). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility.
Modern airplanes have two black boxes: a voice recorder, which tracks pilots' conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft's final moments. Placed in an insulated ( 隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can withstand massive force and temperatures up to 2,000℉. When in deep water, they're also able to emit signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1,2009, are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.In Paragraph 1，the author wants to say the black box_________.
| A．comes from a comic book |
| B．is an necessary device on an airplane |
| C．can prevent disasters |
| D．can control the function of an airplane |
From the black box on the Yemeni airliner_________could be found.
| A．the scene of the crash and the degree of the damage |
| B．the total number of passengers on board |
| C．homing signals sent by the pilot before the crash |
| D．data for analyzing the cause of the crash |
Why was the black box redesigned in 1965?
| A．The early models often got damaged in the crash. |
| B．New materials became available by that time. |
| C．Too much space was needed for its device. |
| D．The early models didn't provide the needed data. |
What do we know about the black boxes from Air France Flight 447?
| A．They have stopped sending homing signals. |
| B．There is an urgent need for them to be reconstructed. |
| C．There is still a good chance of their being recovered. |
| D．They were destroyed somewhere near Brazil. |
