听力原文： Everywhere we look，we see Americans running. They run for every reason anybody could think of. They run for health，for beauty，to lose weight，to keep fit，and because it is the thing they love to do. Every year， for example，thousands of people run in one race，the Boston Marathon，the best known long distance race in the United States. In recent years there have been nearly 5，000 official competitors and it takes three whole minutes for the crowd of runners just to cross the starting line.

You may have heard the story of the Greek runner，Pheidippides. He ran from Marathon to Athens to deliver the news of the great victory 2，500 years ago. No one knows how long it took him to run the distance. But the story tells us that he died of the effort. Today no one will die in a Marathon race. But at the finish line，we see what this race is about；not being first，hut finishing. The real victory is not over one's fellow runners，but over one's own body. It is a victory of will power over fatigue. In the Boston Marathon，each person who crosses that finish line is a winner.

(30)

A．Three minutes.

B．Two minutes.

C．One minute.

D．Five minutes.

第4题

Although the possibility of living a long and happy life nowadays is greater than ever bef

ore, every day we witness the incredible killing on the roads. Man versus the motorcar! It is a never-ending battle which man is losing.

It has been rightly said that when a man is sitting behind a steering wheel, his car becomes the extension of his personality, which often undoubtedly brings out a man's very worst qualities. Normally quiet and pleasant people may become unrecognizable when they are behind a steering wheel. They swear; they are ill-mannered and aggressive, willful as two-year-olds and utterly selfish. All their hidden frustrations, disappointments and jealousies seem to be brought to the surface by the act of driving.

The surprising thing is that society smiles on the motorist and seems to tolerate his behaviour. Everything is done for his convenience. Cities are allowed to become almost uninhabitable because of heavy traffic; towns are made ugly by huge car parks; and the mass annual death becomes nothing more than a statistic, to be conveniently forgotten.

It is high time a world code were created to reduce this senseless waste of human life. With regard to driving, the laws of some countries are extremely loose and even the strictest are not strict enough. A code which was universally accepted could only have a dramatically beneficial effect on the accident rate.

Here are a few examples that might be done. The driving test should be standardized and made far more difficult than it is; all the drivers should be made to take a test every three years or so; the age at which young people are allowed to drive any vehicle should be raised to at least 21; all vehicles should be put through annual tests for safety. Present drinking and driving laws should be made much stricter. Maximum and minimum speed limits should be imposed on all roads. Governments should lay down safety specifications for manufacturers, as has been done in the U.S.A. All advertising stressing power and performance should be banned. These measures may sound terribly harsh. But remember: The world is for human beings, not motorcars.

The main idea of this passage is ______.

A．traffic accidents are mainly caused by motorists

B．thousands of people the world over are killed each year

C．the laws of some countries about driving are too loose

D．stricter traffic laws should be made to prevent accidents

根据下面资料，回答下列各题。 Small increases in temperature found to add power to storms in

the Atlantic. Hurricanes that form. in the Atlantic Ocean are expected to gain considerable strength as the global temperature continues to rise, a new study has found. Using modeling data focused on the conditions in which hurricanes form, a group of international researchers based at Beijing Normal University found that for every 1.8°F (1℃ )rise of the Earths temperature, the number of hurricanes in the Atlantic that are as strong or stronger than Hurricane Katrina will increase twofold to sevenfold. Hurricane strength is directly related to the heat of the water where the storm forms. More water vapor in the air from evaporating ocean water adds fuel to hurricanes that build strength and head toward land. Hurricane Katrina is widely considered the measure for a destructive storm, holding the maximum Category 5 designation for a full 24 hours in late August 2005. It lost strength as it passed over the Florida peninsula, but gained destructive power fight before colliding with New Orleans, killing more than 200 people and causing $ 80 billion in damage. The study points to a gradual increase of Katrina-like events. The warming experienced over the 20th century doubled the number of such debilitating(将人类摧垮的)storms. But the ongoing warming of the planet into the 21st century could increase the frequency of the worst kinds of storms by 700 percent, threatening coastlines along the Atlantic Ocean with muitiple Category 5 storms every year. "Our results support the idea that changes in regional sea surface temperatures is the primary cause of hurricane variability," said Aslak Girnstead, a researcher with the Center for Ice and Climate at the University of Copenhagen. The large impact of small sea-surface temperature increases was more than Girustead and his colleagues had anticipated. The entire study was published in the Proceedings of the National Academy of Sciences. Global temperatures have steadily increased, making the past decade the warmest on record. Earlier this year, climate researchers reported that the Earths temperatures have risen faster in the last century than at any point since the last ice age, 11,300 years ago. The primary cause, a couseusus of scientists has said, is the rising emissions of greenhouse gases like carbon dioxide and methane. Past hurricanes have supported the studys finding that global temperature rise is linked to more destructive storms. According to the National Center for Atmospheric Research, while the frequency of storms doesnt appear to have increased, the percentage of strong ones has risen sharply over the past few decades. The trend may be similar further back in time, but comprehensive hurricane data doesnt exist. According to the team of international researchers based at Beijing Normal University, the rise of the Earths temperature is likely to cause

A.the coming of ice age

B.more Katrina-like or worse hurricanes

C.less intense hurricanes

D.more greenhouse gases in the atmosphere

A Future vehicle What's the Moller Skycar？ While many technological advances occur in an e

A Future vehicle

What's the Moller Skycar？

While many technological advances occur in an evolutionary manner, occasionally a revolutionary technology appears on the horizon that creates startling new conditions and profound changes. Such is the case with the privately developed Moller Skycar, which is named after its inventor. With the inventor permission, I would like to discuss the military potential of this vehicle. The reinforced Moller Skycar variant the military is evaluating is called the light aerial multipurpose vehicle, or LAMV (pronounced "lam-vee").

The LAMV is a vertical take-off and landing aircraft that can fly in a quick, quiet, and agile manner. It is a new type of vehicle that combines the speed of an airplane and the vertical take-off capability of a helicopter with some characteristics of a ground vehicle, but without the limitations of any of those existing modes of transportation.

The LAMV is not operated like traditional fixed-or rotary-wing aircraft. It has only two hand-operators to direct the redundant computer control twists to select the desired operating altitude and moves fore and aft to select the rate of climb. The right-hand control twists to select the vehicle's direction and moves side-to-side to provide transverse (crosswise) movement during the hover and early-transition-to-flight phases of operation; it also moves fore and aft to control speed and braking. Simply put, the LAMV is user-friendly.

The LAMV of the future will be 18 feet long, 10 feet wide, and 6 feet high and weight 2,200 pounds. It will hold four passengers and a payload of 875 pounds (including fuel). The vehicle will have a maximum rate of climb of 6,400 feet per minute and an operational ceiling of 30,000 feet. It will attain a top speed of 390 miles per hour at an altitude of 6,000 feet and a cruising speed of 350 miles per hour at 25,000 feet, and it will have a maximum range of 900 miles at 80 passenger miles per gallon. The LAMV also will be quiet enough to function as an acoustic "stealth" plane at 500 feet. It will have a vertical take-off and landing capability and emergency airframe. parachutes, and it will be capable of using various fuels.

The LAMV features redundant, independent computer systems for flight management, stability, and control. Two airframe. parachutes can be deployed in the event of the vehicle's catastrophic failure. These parachutes ensure that the LAMV and the operator and soldiers it carries can land safely. The Wankel-type rotary engines are very reliable because of their simplicity. The three moving parts in a two-rotor Rotapower engines are approximately seven percent of the number of parts in a four-cylinder piston engine. Each engine room fully encloses the engines and fans, greatly reducing the possibility of injury to soldiers who might be near the vehicle in the event of an engine fire or explosion. Multiple systems check fuel for quality and quantity and provide appropriate warnings. The LAMV can land on virtually any solid surface.

The LAMV is aerodynamically stable. In the unlikely event that sufficient power is not available to land vertically, the LAMV's stability and good glide slope allow the operator to maneuver to a safe area before using the airframe. parachutes. Since computers control the LAMV's flight during hover and transition, the only operator input is to control speed and direction. Undesirable movements caused by wind gusts are prevented automatically.

The usage of LAMV in the future

The potential economic advantages of the LAMV are worth mentioning. Its fuel-efficient engines and ability to operate on various fuels will low fuel costs. The LAMV uses one-fourth of the fuel per passenger mile used by the tilt-rotor V-22 Osprey or high performance helicopters. The LAMV's acquisition cost also will be a significant factor in its favor.

A．Y

B．N
