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 surfaces 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 （蓄水層） into which several heat exchangers （交換器） have been built. The hot water from the street runs through these exchangers, warning 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.

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.

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.

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.

The year is 2094. It has been announced that a comet is heading towards the Earth. Most of it will miss our planet, but two pieces will probably hit the southern half of the Earth.

On 17 July, a piece four kilometers wide enters the Earth’s atmosphere with a massive explosion. About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the sea bed. Huge waves are created and spread outwards from the hole. The wall of water, a kilometer high, rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people drowned.

Before the waves reach South America, the second piece of the comet lands in Argentina. Earthquakes and volcanoes are set off in the Andes Mountains. The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes. Millions of people in the southern half of the Earth are already dead, but the north won’t escape for long. Because of the explosions, the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. The sun won’t be seen again for many years. Wars break out as countries fight for food. A year later, no more than 10 million people remain alive.

Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a piece of object in space. The dinosaurs couldn’t live through the cold climate that followed and they died out. Will we meet the same end?

1.What is mainly described in the passage?

A. A historic discovery.           B. An event of imagination.

C. A research on space.           D. A scientific adventure.

2.When the first piece hits the South Atlantic, it causes      .

A. an earthquake                B. damages to cities

C. an Earth explosion            D. huge waves

3.Why can’t the northern half of the earth escape for long?

A. Because the land is covered with water.

B. Because the light and heat from the sun can not reach the Earth.

C. Because people there can not live at the temperature of zero.

D. Because wars break out among countries.

4.By giving the example of dinosaurs, the author tries to prove      .

A. animals could not live in the cold climate

B. what happened 65 million years ago was an invented story

C. the human beings will die out in 2094

D. the Earth could be hit by other objects in space

Patricia Blues, 29, has a new aim in life: to keep drivers' hands on their steering wheels and off their cell phones. On November 2, 2007, Blues lived through a horrible experience. A motorist dialing a cell phone drove through a stop sign at 45 miles per hour and run into the side of Blues' car. Blues' 2-year-old daughter was killed immediately in the crash.

Blues has since dedicated her time to pushing for laws that would prevent this type of tragedy from happening again.

Cell phones are not the only distractions (分神) that cause accidents. Eating, changing CD, reading maps, talking to passengers, and just reaching for an object on the floor can be dangerous. Therefore, the emphasis should be on educating drivers to avoid all distractions. However, talking on cell phones might be easier to regulate than eating or changing music. At least 34 states have already passed laws to restrict cell phone use in moving cars. No state has banned it yet, but several U. S. cities have. Worldwide, 13 nations, including Australia, England, Germany, Japan and China have banned drivers' use of cell phones in moving cars.

To date, no scientific evidence has been published showing that talking on the phone affects driving safety. But according to a test by some high school students, "driving while on the phone does affect safety and probably shouldn't be done".

64. What happened to Patricia Blues last November? ________.

A. She was seriously injured in a car crash  

B. She lost her daughter in a road accident

D. Her vehicle was destroyed by a motorbike

65. The tragedy was caused by ________.

A. Blues' lack of driving experience   

B. the motorist’s failure of seeing the stop sign

C. Blues' poor car conditions         

D. the motorist's absence of mind while driving

A. to prohibit the carrying of cell phones in cars  

B. to educate drivers to avoid all distractions

C. to ban talking on the phone while driving  

D. to study, harmful results of using cell phones

A. Using cell phone while driving is easier to be controlled by law than other distractions
