Sometimes, the simplest ideas are the best. For example, to absorb heat from the sun to heat water, you need large, flat, back surfaces. One way to do that is to build those surfaces specially, on the roofs of buildings. But why go to all that trouble when cities are full 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 run 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(蓄水層) into which several heat exchangers（交換器）have been built. The hot water from the street runs through these exchangers, warming the groundwater, 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.
小題1:Which of the following is true according to the first two paragraphs ?
Arian de Bondt got his idea from his boss.
Large, flat, black surfaces need to be built in cities.
The Dutch engineer’s system has been widely used.
Heat can also be collected from asphalt roads.
小題2: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.
小題3: 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
D．less heat may be collected in winter than in summer
小題4:What is most likely to be discussed in the paragraph that follows ?
A．What we shall do if the system goes wrong.
B．What we shall do if there are no asphalt roads.
C．How the system cools the building in summer.
D．How the system collects heat in spring and autumn.

It is not unusual at all for teens to answer their parents with one work answers. “Where are you going?” “Places.” “When will you be back?” “Sometime.” “Who will you be with?” “People.”
That means that the days of your children bounding in the front door with the details of their day are over. They are breaking away from you so that they’ll be able to stand on their own as a young adult.
Some parents feel sad about this loss of their children’s closeness. Of course you miss those conversations and friendly talks. Once your children move out after high school and establish themselves confidently as a young adult, they’ll come back for easy conversations and even ask for advice. But in order to determine who they are right now they need to separate from you.
Your job, however, is to keep them safe——and that requires knowing there they are and who they are with. Let them know clearly that it’s not because you want to dominate their life and control them; it’s because it’s a safety issue for family members to keep track of one another.
When they’re home and sit down to eat a meal, sit down with them. You need to open up to them about your life. Tell them of an interesting incident at the office, let them in on a bit of family gossip(閑談), discuss a piece of news with them. They are glad that you see them as old enough to be in on a few experiences of your life. By letting a teen in on your life, they just may let you in of theirs
小題1:The underlined word “That” in Paragraph 2 probably refers to “      ”.
A．teens no longer tell parents their detailed information
B．teens don’t tell parents where they had been any more

D．parents are occupied by doing their business
小題2:It can be inferred from the passage that       .

B．teens quarrel a lot with their parents
C．teens don’t want to live with other family members
D．some parents feel distant from their teenage children
小題3:The author believes that teens’ one-word answers show      .
A．their awareness of independence
B．their physical and mental changes
C．a(chǎn)n unpleasant parent-child relationship
D．their wishes for keeping silent
小題4:What’s the main idea of the last paragraph?
A．Parents should understand their children.
B．parents should keep their children safe.
C．Parents should open their hearts to their children.
D．Parents should give their children enough freedom.
小題5:What’s the author’s purpose in writing the passage?

A farmer had some puppies he needed to sell. He painted a sign advertising the pups and set about nailing it to a post on the edge of his yard. As he was driving the last nail into the post, he felt a tug on his overalls. He looked down into the sad eyes of a little boy.
“Mister," he said, "I want to buy one of your puppies." 
"Well," said the farmer, as he rubbed the sweat of the back of his neck, “these puppies come from fine parents and cost a good deal of money."
The boy dropped his head for a moment. Then reaching deep into his pocket, he pulled out a handful of change and held it up to the farmer. "I've got thirty- nine cents. Is that enough to take a look?”  
"Sure," said the farmer.
And with that he let out a whistle. "Here, Dolly!" he called.
Out from the doghouse and down the ramp ran Dolly followed by four little balls of fur. The little boy pressed his face against the chain link fence. His eyes danced with delight.
As the dogs made their way to the fence, the little boy noticed something else stirring inside the doghouse. Slowly another little ball appeared; this one noticeably smaller.
Down the ramp it slid. Then in a somewhat awkward manner, the little pup began hobbling toward the others, doing its best to catch up....
"I want that one," the little boy said, pointing to the runt.
The farmer knelt down at the boy's side and said, "Son, you don't want that puppy. He will never be able to run and play with you like these other dogs would."
With that the little boy stepped back from the fence, reached down, and began rolling up one leg of his trousers. In doing so he revealed a steel brace running down both sides of his leg attaching itself to a specially made shoe. Looking back up at the farmer, he said, "You see sir, I don't run too well myself, and he will need someone who understands."
With tears in his eyes, the farmer reached down and picked up the little pup. Holding it carefully he handed it to the little boy.
"How much?" asked the little boy.
"No charge," answered the farmer, "There's no charge for love."
The world is full of people who need someone who understands. It's National Friendship Week.
小題1:How many baby pups did the farmer have for sale?
A．3B．4C．5D．6
小題2:Why did the farmer agree to sell the boy one of the puppies?

       Scientists in the United States say plant life has increased on Earth in the past twenty years and that in every area of plant growth the increase is the result of weather conditions.
Eight scientists from across the United States did the study. The space agency NASA and the Department of Energy paid for it. The findings were published in the magazine Science.
The researchers spent one and a half years examining weather satellite information. The information was recorded from 1982 to 1999. That period was one of the warmest on record. Researchers found that rainfall generally increased during that time.
The satellites measured the number of leaves on plants and the amount of sunlight taken in. The scientists used that information to estimate what is called net primary production. This is total amount of carbon stored in land plants.
The scientists report a 6% increase in stored carbon since 1982. They say gains were high in equatorial areas, especially around the Amazon River in South America. The area alone had a 1% increase in the net primary production.
Ramakrishna Nemani of the University of Montana in Missoula headed the study. He says reduced cloud cover led to growth in Amazon area. He also says the lack of clouds allowed more sunlight to get through. More sunlight meant increases in photosynthesis(光合作用). That is the process by which plants use energy from sunlight to produce the chemicals they need to grow.
Northern Canada, the north-central United States and northern Europe were second in increased plant growth. Ramakrishna Nemani says a rise in temperature helped plants there.
All together, the report says 25% of areas of plant life on Earth experienced increases. But the scientists also note increase in the number of people on Earth and carbon dioxide levels in the atmosphere. Ranga Myneni of Boston University in Massachusetts, another study scientist says humans use about half the net primary production on Earth. And he notes that the world population grew by 36% during the period of time studied.
小題1:Which of the following is in charge of the study?
A．The space agency NASA of the US.
B．The Department of Energy of the US.
C．Ramakrishna Nemani in Missoula.
D．Ranga Myneni in Massachusetts.
小題2:What’s the main cause of the plant growth put forward by the study?
A．Growth in population.
B．Regional features.
C．Seasonal variation.
D．Weather conditions
小題3: Why do scientists believe that reduced cloud cover has led to the plant growth in       the Amazon area?
A．Because plants could take in more sunlight.
B．Because plants could get more rainfall.
C．Because plants could enjoy cooler air.
D．Because plants suffer less from natural disasters.
小題4: Which of the following descriptions about the years from 1982 to 1999 is TRUE?
A．It was the warmest on record.
B．Rainfall decreased little by little.
C．World population grew by 25%.
D．Stored carbon increased by 6%.

Many of us have heard of the saying: everything is possible if you can just believe. But few of us really know the power of faith and perseverance(堅(jiān)定).  South African swimmer Natalie du Tiot embodies(體現(xiàn))those virtues.
Du Tiot, 24, became the first swimmer to compete in both the Olympic Games and the Paralympics (殘奧會(huì))in Beijing. Although she finished 16th in the tough 10km marathon in the able-bodied Games, she has collected three golds in the Paralympics so far.
One of the most successful disabled athletes of all time, Natalie du Tiot was already a promising swimmer when she lost her leg in a motorcycle accident in 2001, at just 17.
“There are a lot of dark moments,” she said, “There are some days when I cry. But I try to remember that better days are ahead. You just go on.”
Within a few months, she was back in the swimming pool.
She still completes and still succeeds. The only difference is she has switched to longer events—from 200m and 400m individual medley to 800m and 1,500m freestyle—to make up for her loss of speed with only one leg. But she made no adjustment to her mental look(精神面貌).
“Going out in the water, it feels as if there’s nothing wrong with me. It doesn’t matter if you look different. You’re still the same as everybody else because you have the same dream.”
She is the owner of many world records, and she also won gold when competing against able-bodied swimmers in the 1,500m freestyle at the All African Games in 2007.
But there is no magic recipe(秘訣) for success. It all comes down to hard work and determination. “She is stubborn, which is good and bad,” said her coach Karoly Von Toros. “Good for the swimming, but bad for the coach.”
There is a poem that hangs on her wall that reads:
The tragedy (悲劇)of life does not lie in not reaching your goals;
The tragedy of life lies in not having goals to reach for.
小題1: Natalie du Tiot is a vivid example that____________________.
A．you are what you believe
B．your biggest enemy is yourself
C．results are not so important as the process
D．you must set reasonable goals or you will fail
小題2:According to the text , Natalie du Tiot became________________.
A．the first athlete to compete with able-bodied swimmers in the world
B．the youngest disabled swimmer to break the world record in the 1,500m freestyle
C．the youngese disabled swimmer to collect three golds in a single Paralympics
D．the first swimmer to compete in both the Olympic Games and the Paralympics
小題3:Which of the following is the correct order of the events that happened to Natalie du Tiot？
a. She won gold at the All Africa Games.
b. She finished 16th in the tough 10km marathon in the Olympics
c. She adjusted herself to long events.
d. A motorcycle accident disabled her.
A．cdabB．dcbaC．dcabD．dacb
小題4:In dark moments it was_______________ that pushed her on.
A．her coachB．her familyC．hope and faithD．her love of swimming
