Can you imagine astronauts' everyday life in space? They also need to eat,  sleep, exercise and relax. They do the same things as us, but they do them differently.
On Earth, we put food on a plate. Gravity holds the food down and keeps it on a place. But there is almost no gravity in space, so food can float （漂�。゛way, and astronauts must eat carefully.
Sleeping is very different in space. Some astronauts like to float in the air, but most like to be in a sleeping bag. They tie the bag to a wall so that they won't float away at night.
Exercise is very important in space. On Earth,  your legs carry your body,  but in space, astronauts float, so they do not use their legs often. This is very bad for their legs, so they must exercise for thirty minutes every day.
After a day's work, astronauts relax. They may listen to music, read, watch films, play games, or talk to their friends and families on the radio. Sometimes they just enjoy floating in the air.
小題1:What does the underlined word "gravity" mean in Chinese?
A．平衡B．引力C．磁性D．重力
小題2:Why do astronauts tie the sleeping bag to a wall?
A．Because in that way they won't float away.
B．Because that makes them sleep well.
C．Because they can't get to sleep if they don't do that.
D．Because the sleeping bag is not safe enough.
小題3:What's the main idea of the passage?
A．It is about the importance of gravity.
B．It is about astronauts' everyday life in space.
C．It is about the differences between space and Earth.
D．It is about how to avoid （避免） floating away while sleeping.

Taking away a city’s rubbish is a big job. Every day trucks come into a city to collect it. Most rubbish is made up of things we can’t eat or use. If we kept these things we would soon have a mountain of rubbish.
In some cities the rubbish is collected and taken outside of the city to a dump(垃圾站). Often the city dump is placed where the ground is low or there is a big hole. The kitchen rubbish is broken into small pieces and sent into the sewage system. The sewagesystem takes away the used water from toilets, bathtubs(澡盆) and other places.
To keep mice and flies away, some earth is used to cover the newly dumped rubbish. Later, grass may be planted on the rubbish-filled land. Finally, a house or a school may be built there, and then you’d never know that this had once been an old rubbish dump.
In other cities the rubbish is burnt in special places. The fire burns everything but the metal. Sometimes the metal can be used again in factories where things are made of metal. The food parts of rubbish are put in special piles where they slowly change into something called humus(腐殖土), which looks like black earth. It is rich with kinds of things that feed plants and help make them grow.

A long walk in the desert or the mountains can be exciting. And it’s a great way to keep fit. If you carry a tent and some food, you can camp overnight. But wild places can be dangerous. Here’s how you can enjoy walking and camping safely.
Before your trip
☆ Tell someone where you are going and when you expect to return. If you don’t return on time, the people at home will know that you are lost or in trouble. They will know where to look for you.
☆ Make sure you’ve got a good map of the area that you’re going to.
☆ Make sure you’ve packed the right equipment for your activities. The desert is often hot, but nights can be very cold, and sometimes there are big rainstorms. In the mountains, the weather can change suddenly. A sunny day can turn cold and cloudy quickly.
The tools for survival(生存)
Sunglasses, sun hat, sun cream, windproof jacket, good walking shoes or boots, food, water, maps, compass, first-aid kit, matches, rope, knife, ground sheet,
the pack to carry your equipment.
What to do if you get lost
☆ If you’re in a car and it has broken down, stay with your car.
☆ If you are not traveling by car, make yourself easy to see. A signal fire can be seen at night. During the day, smoke may be used to show where you are. A brightly-colored blanket(毯子) may help rescuers to find you.
☆ Stay where you are.
☆ If you walk for any reason, avoid walking during the hottest part of the day. Morning and evening walking is better for saving your energy water.
☆ Keep yourself away from the rain, wind and sun, but remember: try to make yourself be in sight.

IQ（intelligence quotient智商）is a score that shows a person’s level of intelligence.
People used to believe that some people are born with a high IQ and some aren’t.
  32 , a study by scientist at University College London has challenged（挑戰(zhàn)）this idea. According to an article last October on the Journal Nature, scientists are beginning to think that our IQ is not a constant（不變的）score.
The scientists tested 33 healthy young people in 2004 between the ages of 12 and 16. Then they did tests again four years later, when the same people were between 16 and 20.
Scientists found big changes in the IQ scores between 2008 and 2004. Some  33 and some fell  34 as many as 21 points.
To test whether these scores were meaningful, the scientists compared them with results from brain scans（掃描）. They found that the IQ changes matched changes in the structure（結(jié)構(gòu)）of the subjects’ brains. “A change in 20 points is a huge  35 ,” said Professor Cathy Price, who led the research. He said it could mean the difference between an average and a  36 person. The team has not found a clear cause for these changes. However, they say it is  37 that education plays a role in changing IQ.
“Here we have shown that children’s  38 is likely to be still developing, ” says Price. “We have to be careful not to write off  39 performers at an early stage. In fact, their IQ may improve in a few more years. ”
