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.

Have you felt annoyed when a cell phone (手機)rings during the class? Something must be done to stop this. Now in New York City, USA, a rule is carried out（執行） in schools. Students can’t even bring cell phones to school. Is it a good thing or not?
Anxious（焦慮的） parents say that cell phones are an important tool in holding New York City’s families together.
“I worry about it,” said Elizabeth Lorris Ritter, a mother of a middle school kid. “It’s necessary in our everyday life. We have a washing machine, we have running water, and we have cell phones.”
A number of Americans think cell phones connect them to children on buses, getting out from subways, walking through unknown places.
“I have her call me when she gets out school,” said Lindsay Walt, a schoolgirl’s mother. “No one in New York is going to let their children go to school without a cell phone.
What about the cell phone owners, the students? Most of the students said that cell phones were necessary and the cell phone was like an extra(額外的)hand or foot for them.
“I feel so empty,” said May Chom, 14. “There is also no way to listen to music on the way to school without my phone. It will be a really, really boring trip.”

The rockets take astronauts and man-made satellites into space. The satellites are used for communication, weather monitoring and research. But how do satellites stay up without falling down?
There are two opposite forces (力量) acting on the satellite. One of them is the force of gravitation (地心引力), which tries to pull the satellite towards the earth. The other force is created by the rotation (旋轉) of the satellite around the earth. This force tries to take the satellite away from the earth. With these two forces, the satellite goes round and round. The gravitational pull of the earth (the force which pulls everything towards the ground) is like a rope which keeps the satellite from flying away.
Everything that goes up has to come down. It is only a matter of time before a satellite comes back to the earth. As time goes by, the satellite loses its speed, which makes the gravitational pull stronger than the force pulling it away. This makes the satellite crash (墜落) down to the earth.
小題1:Which of the following uses of satellites is NOT mentioned?

A．communication

B．monitoring the weather condition

C．doing some research

D．taking pictures

小題2:The force that pulls the satellite towards the earth is created by ________.

A．the earth

B．the satellite itself

C．the rotation of the satellite

D．the rope

小題3:Why can’t the satellites fly away?

A．Because of the force from the earth.

B．Because the satellite is too big.

C．Because of the force created by the rotation of the satellite around the earth.

D．Because people on earth have made ropes to tie the satellites tightly.

小題4:The satellite will finally crashes down to the earth ________.

A．when it flies faster

B．when its speed slows down

C．when people cut the rope

D．when there is no electricity in it

小題5:Which of the following is TRUE according to the passage?

A．There are four forces acting on the satellite.

B．The force of gravitation makes the satellite go round and round.

C．As time goes by, the satellite will finally fall down.

D．The satellite will stay in space forever.

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 （漂浮）away, 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.
