Sometimes, the simplest ideas are the best.For example, to absorb heat from the sun to heat water, you need large, flat, black surfaces.One way to do that is to build those surfaced specially, on the roofs of buildings.But why go to all that trouble when cities are rub of black surfaces already, in the form of asphalt(柏油)roads?
Ten years ago, this thought came into the mind of Arian de Bondt, a Dutch engineer.He finally persuaded his boss to follow it up.The result is that their building is now heated in winter and cooled in summer by a system that relies on the surface of the road outside.
The heat - collector is a system of connected water pipes.Most of them ran from one side of the street to the other, just under the asphalt road.Some, however, dive deep into the ground.
When the street surface gets hot in summer, water pumped through the pipes picks up this heat and takes it underground through one of the diving pipes.At a depth of 100 metres lies a natural aquifer(蓄水层)into which several heat exchangers have been built.The hot water from the street runs through these exchangers, warming the ground - water, before returning to the surface through another pipe.The aquifer is thus used as a heat store.
In winter, the working system is changed slightly.Water is pumped through the heat exchangers to pick up the heat stored during summer.This water goes into the building and is used to warm the place up.After performing that task, it is pumped under the asphalt and its remaining heat keeps the road free of snow and ice.
68.Which of the following is true according to the first two paragraphs?
A.Arian de Bondt got his idea from his boss.
B.Large, flat, black surfaces need to be built in cities.
C.The Dutch engineer's system has been widely used.
D.Heat can also be collected from asphalt roads.
69.For what purpose are the diving pipes used?
A.To absorb heat from the sun.
B.To store heat for future use.
C.To turn solar energy into heat energy.
D.To carry heat down below the surface.
70.From the last paragraph we can learn that ______.
A.some pipes have to be re - arranged in winter
B.the system can do more than warming up the building
C.the exchangers will pick up heat from the street surface
D.less heat may be collected in winter than in summer
Once a circle lost a piece of its own. The circle wanted to be whole, so it went around looking for its missing piece. But because it was incomplete(不完整的), it could only roll very slowly. It enjoyed the flowers and the sunshine along the way. It talked with worms. It found lots of different pieces, but none of them fit. So it left them all by the side of the road and kept on looking for the missing piece.
Then one day the circle found a piece that fit perfectly. It put the missing piece into itself. It could be whole, with nothing missing. It was so happy and began to roll. Now that it was a perfect circle, it could roll very fast, too fast to see flowers or talk to worms. It realized how different the world was when it rolled so quickly. It felt so sad that it stopped, left its found piece by the side of the road and rolled away slowly.
Sometimes we are perfect when we lost something. A man who has everything is a poor man in some ways. He will never have hopes, dreams or something better. He will never know someone is loving him or someone is giving him something he has always wanted or never had.
We couldn’t be perfect, but we must be brave enough to love, strong enough to forgive, kind enough to share happiness with others and clever enough to know there is enough love around us and then we can always live a wonderful time in our lives.The circle rolled very slowly because it __________.
A.spent much time talking to worms |
B.wanted to enjoy the sunshine |
C.was looking for its missing piece |
D.lost a piece of its own |
After it was whole again and rolled fast, the circle __________.

If a man owns everything, he’ll be __________ in some ways.
A.perfect | B.poor | C.happy | D.strong enough |
The story mainly tells us that __________
A.nobody loves us if we give nothing |
B.a man who has everything is the happiest |
C.losing something may not be a bad thing sometimes |
D.we are not whole when we lose something |
Talking on a mobile phone is expensive, so a lot of people send text messages. Text messages are much cheaper than talking on a mobile phone, and you can make it cheaper by making the words shorter. You can do this by taking out “unimportant” letters in the words and using numbers instead of words (2 =" to," 3 =" free," 4 =" for," 8 =" ate," so h8 =" hate," etc.). You can also keep away from using punctuation (标点). Here is an example: Do U wnt 2 g 2 th cnma tnite (Do you want to go to the cinema tonight?)

Whr hv U bn? Iv bn wtng hrs fr a cll.

Everyone needs friends. There is an old saying, “Friends are God’s way of taking care of us.” But how do you find real friendship and keep it?
The American writer Sally Seamans tells young students some smart ways to find friends. Sally says finding friendship is just like planting a tree. You plant the seed and take care of it to make it grow.
First, you should choose a friend. What makes a good friend? It is not because a person has money or good looks. A good friend should be kind and patient. For example, if you have a bad day, a good friend should listen to your complaints and do his or her best to help. To make a friend, you cannot be too shy. You should make each other happy and share your lives.
But things cannot always he happy. Even the best friends have fights. What should you do when you have a fight with your friend? You have to talk to him or her. When there is no one around, have an honest talk. If he or she doesn’t want to talk, you could write a letter.

How hard we have all prayed(祈祷) to grow up quickly, and looked forward to the happy days of being a grown-up and enjoying the many interests that a youth should have.
