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.

This is the age of being busy. Many of us live in busy places and have busy lives. Even the roads are busy as we try to get from here to there. Adults are busy going to jobs and taking care of their families. Kids are busy, too, going to school and doing a lot of homework after school and on weekends.
Busy isn’t bad, necessarily. If you are not busy enough you might be bored. But if you are too busy, you might break down. For example, if you have a soccer game that runs late on a school night and you haven’t eaten dinner or done your homework, that’s a not-so-fun kind of busy. We wanted to know what kids thought, so we did a kidsPoll about being busy with 882girls and boys aged 9 to 13.
Almost all of them said they felt stressed because they were too busy. About half said they felt this way once in a while or some of the time. But 17% said they felt this way most of the time and 24% said they felt this all the time! Oh dear, that’s no fun.
Only 4% of kids said they wanted less free time and 18% said they already had just the right amount. But, no big surprise, 61% of kids wish they had a lot more free time. If they had more time, most would spend it hanging out or playing with friends.
Often, adults plan large parts of a kid ’s day, especially during the school year. kids can’t tell their parents they’ll be skipping school(逃学) today to get more free time! But they can tell their parents they’d like to play a game or read a book during their free time instead of watching TV.The purpose of the first paragraph is to _____.

Doris was born in New Zealand but gave up her homeland when the couple met and married in the late 1990s. But New Zealand is close to both their hearts and the attraction of family and friends, and the good fishing helped to persuade them to move.
Doris, who has five children and nine grandchildren, supported her husband's application to settle in New Zealand. The paperwork took five months. Eric says, "We not only had to produce a marriage certificate（证书） but we had to produce evidence that we were in a long and stable relationship!" He also said he was not asked about his age but had to show that he could support himself financially (财政上) in New Zealand.

Even facts “forgotten” by people during a busy day may be retrieved if this is followed by a good night’s sleep.
Researchers from the University of Chicago asked volunteers to remember simple words．Many found their memories letting them down towards the end of the day, but the following morning, those who had slept well could recall much more.
Researchers, writing in the journal Nature, said the brain could “rescue” lost memories during the night.
When the brain is first asked to remember something that memory is laid down in an “unstable” state, meaning that it is possible that it could be lost．At some point, the brain consolidates those it deems important into a “stable”, more permanent state．However, the Chicago researchers suggested that it was possible for a “stable” memory to be made “unstable” again．This would mean that memories could be modified then filed away again in the face of new experiences.
The 12 volunteers tested in the experiment were played words created through a speech synthesizer which were purposely difficult to understand．Initially, the written version of the word from the audio version only．Tests revealed that the ability to recall the right word tended to tail off as the day ended.
However, when the volunteers were retested after a good night’s sleep, they were able to recall some words that they had “ forgotten” the previous evening.
Dr Daniel, one of the study authors, said: “Sleep consolidates memories, protecting them against subsequent interference or decay．Sleep also appears to “recover” or restore memories.” He said: “If performance is reduced by decay, sleep might actively recover what has been lost.”
Dr Karim Nader, from the Department of Psychology in McGill University in Montreal, said: “Memory research is undergoing a transformation---no longer is memory thought to be a hard-writing of the brain, instead it seems to be a process of storage and restorage.”
Sleep helps some memories “mature” and also prunes out unimportant memories.What does the first paragraph implies?
| A．A busy day makes people forget things easily. |
| B．People need a good night’s sleep after a busy day. |

| C．Once the memory become stable, it will never become unstable again. |
| D．Sleep can protect memories from being harmed. |
A sunflower is a sunflower. A mobile phone is a mobile phone. But can you combine the two to do something for your local environment? As early as next year it may well be possible. When you have finished with your mobile phone you will be able to bury it in a garden or a plant pot and wait for it to flower.
A biodegradable (生物所能分解的) mobile phone was, this month, introduced by scientists. It is hoped that the new type of phone will encourage consumers to recycle.
Scientists have come up with a new material over the last five years. It looks like any other plastic and can be hard or soft, and is able to change shape. Over time it can also break down into the soil without giving out any poisonous chemicals. British researchers used the new material to develop a phone cover that contains a sunflower seed. When this new type of cover turns into waste, it forms fertilizers. These feed the seed and help the flower grow.
Engineers have designed a small transparent (透明的) window to hold the seed. They have made sure it only grows when the phone is thrown away. “We’ve only put sunflower seeds into the covers so far. But we are working with plant experts to find out which flowers would perform best. Maybe we could put roses in next time,” said one scientist.
As phone technology is developing so quickly, people are constantly throwing their mobiles away. This means manufacturers are under pressure to find ways of recycling them. Some 650 million mobile phones have been sold this year. Most of them will be thrown away within two years, adding plastic, heavy metal and chemical waste to the environment. A biodegradable cover can offer some relief (缓解) for nature , according to the scientists.
“The seed comes out and the flower grows in the pot so you don’t have to concern yourself with the phone when you have finished using it,” said Kerry Kirwan. She leads the research team, which is based at the University of Warwick in Britain.What is the purpose of this passage?
| A．To tell the popularity of biodegradable cell phones. |
| B．To persuade the reader to buy the biodegradable cell phone. |

| B．phone-makers will benefit much more from the new type of phone |
| C．the new type of phone will certainly be popular with users all over the world |
| D．the phones that can be recycled are available only in Britain now |
Green is an important color in nature. It is the color of grass and the leaves on trees. It is also the color of most growing plants.
Sometimes, the word green means young, fresh and growing. Sometimes, it describes something that
is not yet ripe or finished. For example, a greenhorn is someone who has no experience, who is new to a situation. In the fifteenth century, a greenhorn was a young cow or ox whose horns(角) had not yet developed. A century or so later, a greenhorn was a soldier who had not yet had any experience in battle. By the eighteenth century, a greenhorn had the meaning it has today—a person who is new in a job.
Someone who has the ability to grow plants well is said to have a green thumb. The expression comes from the early nineteen hundreds. A person with a green thumb seems to have a magic touch that makes plants grow quickly and well. You might say that the woman next door has a green thumb if her garden continues to grow long after your plants have died.
The Green Revolution is the name given some years ago to the development of new kinds of rice and other grains. The new plants produced much larger crops. The Green Revolution was the result of hard work by agricultural scientists who had green thumbs.
Green is also the color used to describe the powerful feeling, jealousy(嫉妒). The green-eyed monster is not a frightening creature from outer space. It is an expression used about four hundred years ago by British writer William Shakespeare in his play “Othello”. It describes the unpleasant feeling a person has when someone has something he wants. A young man may suffer from the green-eyed monster if his girlfriend begins going out with someone else. Or, that green-eyed monster may affect your friend if you get a pay rise and she does not. Greenhorn now refers to ____.
| A．a person who is new in a job | B．a new solider |
| C．a young horse | D．None of above |
A person who has a green thumb is a person ____.
| A．who is good at growing plants | B．whose thumbs are in green color |
| C．whose garden is greener than others’ | |
| D．who is younger than his neighbors |
The author is actually talking about ____.
| A．colors | B．language | C．politics | D．agriculture |
Which of the following statements is NOT true according to the passage?
| A．In about the 16th century, a greenhorn meant an experienced soldier. |
| B．The Green Revolution may have some connection with green thumbs. |
| C．The green-eyed monster was probably created by William Shakespeare. |
| D．The green-eyed monster can be used to describe a person who is jealous. |
