Have you ever seen a car without a driver? It sounds crazy, but these computer-driven cars may soon be filling roads near you. Companies like Google and Tesla have been designing and testing such cars. They just need to run final tests to make sure whether they can run alongside human-driven cars on the road.

The cars have sensors (传感器) all around which can detect other cars and blocks in the road. Sensors on the wheels help when parking, so the car knows how far it is from the edge of the road or other parked cars. Road signs are read by cameras, and satellite navigation systems (卫星导航系统) are used so the car knows how to get to your destination. All you have to doistypein the address! Finally, a central computer system takes in all the information it receives from the sensors and cameras and uses this to work out when to stop and speed up.

Sounds like your idea of heaven? Sitting back, looking out of the windows and watching a film while driving would be possible with this new technology. Computers would drive more safely than people — they don’t get disturbed by phones or talking, they would obey the speed limit and have quicker reaction in case of an emergency.

However, driverless cars have many disadvantages. Computers would have difficulties making some decisions: if a child ran into the road, would the computer choose to hit the child or turn quickly to hurt the car’s passengers? And should children, or drunk people, be allowed in a driverless car by themselves? Besides these questions, many people may lose their jobs. For example, bus, taxi, train and tram drivers, as well as driving instructors.

I don’t really want a driverless car — butitis only a matter oftime before ordinary people will be able to afford them on our roads.

1.What does paragraph 2 mainly talk about?

A.How a driverless car works.

B.What we need to drive a driverless car.

C.The tests a driverless car needs to pass.

D.The advantages of a driverless car.

2.What does the underlined word “detect” in paragraph 2 mean?

A.attract. B.help.

C.discover. D.disturb.

3.From the text we can learn that the driverless car___.

A.can run faster than a traditional one

B.is suitable for a child to sitin it alone

C.has been used in many areas in the world

D.has many problems not yet solved

4.What is the author’s attitude towards the driverless car?

A.Positive. B.Negative.

C.Objective. D.Doubtful.

Terrafugia Inc. said Monday that its new flying car has completed its first flight, bringing the company closer to its goal of selling the flying car within the next year. The vehicle —named the Transition – has two seats, four wheels and wings that fold up so it can be driven like a car. The Transition, which flew at 1,400 feet for eight minutes last month, can reach around 70 miles per hour on the road and 115 in the air. It flies using a 23-gallon tank of gas and burns 5 gallons per hour in the air. On the ground, it gets 35 miles per gallon.

Around 100 people have already put down a $10,000 deposit to get a Transition when they go on sale, and those numbers will likely rise after Terrafugia introduces the Transition to the public later this week at the New York Auto Show. But don’t　 expect it to show up in too many driveways. It’s expected to cost $279,000.And it won’t　 help if you’re stuck in traffic. The car needs a runway.

Inventors have been trying to make flying cars since the 1930s, according to Robert Mann, an airline industry expert. But Mann thinks Terrafugia has come closer than anyone to making the flying car a reality. The government has already permitted the company to use special materials to make it easier for the vehicle to fly. The Transition　 is now going through crash tests to make sure it meets federal safety standards.

Mann said Terrafugia was helped by the Federal Aviation Administration’s decision five years ago to create a separate set of standards for light sport aircraft, which are lower than those for pilots of larger planes. Terrafugia says an owner would need to pass a test and complete 20 hours of flying time to be able to fly the Transition, a requirement pilots would find relatively easy to meet.

1.What is the first paragraph mainly about?

A. The basic data of the Transition.

B. The advantages of flying cars.

C. The potential market for flying cars.

D. The designers of the Transition.

2.Why is the Transition unlikely to show up in too many driveways?

A. It causers traffic jams.

B. It is difficult to operate.

C. It is very expensive.

D. It burns too much fuel.

3.What is the government’s attitude to the development of the flying car?

A. Cautious　　 B. Favorable.

Finally, the long-awaited flying car is almost here.

AeroMobil, a Slovakian company, plans to start selling its creation, the AeroMobil 3.0, in 2018.

The company claims on its site that the vehicle “transforms in seconds from an automobile to an airplane” by using “existing infrastructure created for automobiles and planes.” The vehicle is gas-powered and has wings that fold, which allows it to be parked like a car, though it is nearly 20 feet long.

The company’s web site features a video where the AeroMobil 3.0 drives out of a hangar (飞机库) and goes down a highway, sharing the road with regular cars until it arrives at an airstrip. The car then unfolds its wings and takes off from a stretch of grass, rather than a paved tarmac (停机坪) , and flies through the air like any other small airplane.

AeroMobil spokesman Stefan Vadocz said his company hasn’t nailed down an exact price because it’s not ready yet.

“The prototype is a work in progress,” he said in an email. But he said to expect the price to be several hundreds of thousands of euros, somewhere in between a sports car and a light sports aircraft. The vehicle seats two people — the pilot and a passenger — and its single propeller (螺旋桨) is located to the rear of the plane. The company said the car’s top speed on the road is at least 99 mph and while flying is at least 124 mph. It can fly for 435 miles before running out of gas. It has a steel framework and carbon coating and is powered by a Rotax 912, a four-cylinder aircraft engine from BRP of Austria.

Flying cars aren’t exactly new. The concept has been around since long before “The Jetsons” popularized the idea in the 1960s. It’s been a regular topic in Popular Science ever since the famous pilot Eddie Rickenbacker in World War I wrote about it in 1924. But getting a practical, reliable flying car off the ground has been a serious challenge. Glenn Curtiss, a strong competitor of the Wright Brothers, discovered this in 1918 when he developed the Curtiss Autoplane. It turned out to be more of a hopper than a flyer, so it failed to take off with the public.

The AeroMobil 3.0 has at least one competitor, the Terrafugia Transition, which also runs on gas and has folding wings. Terrafugia has said in the past that it plans to release the Transition into the market this year.

1.The AeroMobil 3.0 has the following features EXCEPT that 　　　　　　 .

A. it can transform between a car and an airplane quickly

B. it is as convenient to park as a regular car

C. it can share the same road with regular cars

D. it has to be powered by special fuel

2.The underlined word “prototype” in Paragraph 6 is closest in meaning to _________.

A. perfect version　　 B. fashionable design　　 C. original model　　 D. committed engineer

3.We can learn from the passage that __________.

A. Glenn Curtiss was a pioneer in making a flying car

B. since 1924 the flying car has become the most popular topic worldwide

C. the Transition will definitely defeat the AeroMobil 3.0 on the market

D. the AeroMobil 3.0 is expected to be as cheap as a regular car

4.The passage is mainly about _________.

A. the working principles of a flying cars

B. the advantages of the AeroMobil 3.0 over regular car

C. the comparison between different products

D. the introduction to a new invention

It has been a dream for 30 years but now the world’s first flying car is set to hit the roads this year.

Ever since the “Back to the Future” movies lit up our screens in the 1980s，designers have dreamt of cars that could take to the sky at the push of a button．And now pilots can order their own “roadable” plane for just £ 127,000.

The plane, which has fold-out wings that span(翼展)17.5ft，has a range of flying distance of 460 miles and can be up to 115 mph．Back on the land，it can also travel at“highway speeds”in car mode(模式)．

Fueling the 19ft. long plane couldn’t be simpler----you just drive it into a petrol station and fill it up．

A spokeswoman said, “You can keep you ‘light-sport airplane’ in your garage.But because it needs a short runway to take to the air, you will have to drive to your local airport，fly up to 460 miles, land，and drive directly to your destination．You will always be ready to drive or fly．"

The spokeswoman added,“Never let bad weather change your trip.You call simply divert(改道)and continue on the ground until the weather clears.”　　

There is no risk to you—This is only the chance for you to be the first at your home field to unfold your wings and fly into the future．

1.According to the text, the“roadable”plane________.

A. can fly at“highway speeds”in car mode　　

B. is 19ft long and 17.5ft wide inside

C. is a kind of car with fold-out wings

D. can only travel on the highway

2.We can infer that in the“Back to the Future”movies_________. ‘’

A. cars can fly in the sky

B. pilots have no cars to drive

C. pilots can’t afford a“roadable”plane

D. there are some skillful pilots　

3.The last sentence of the text aims to__________．

A. ask people to unfold their wings and fly into the future

B. show people the use of the“roadable”plane

C. tell people only the“roadable”plane can fly in the future

D. call on people to buy the“roadable”plane

4.If you meet with a thunderstorm in your“roadable”plane in the skies，you can ________ ．

Flying devices called drones(无人机) may be one of the most important technologies of the future.

The number of jobs for people who know how to design, build and control them is increasing. Because of this increase, several U.S. universities have started offering degrees in unmanned aircraft systems, or UAS.

One of these universities is the University of Washington in Seattle. Ward Handley is seeking a master’s degree in UAS at the university. When the drone program first began, he did not think it was a good idea. “Drones can be used to invade privacy(侵犯隐私).” He said. But later, Handley changed his opinion. He said, “I think there are good enough purposes for them.”

The FAA (the part of the U.S. government that controls air travel and traffic) is creating new rules to control the use of drones, however. A new law requires drone owners to register(登记) their drones. People who do not register their drones could face fines of up to US$20,000.

The new rules may also present problems for students. One problem is finding a legal place to fly.

Students at Blue Mountain Community College fly inside the college gym. In Seattle, University of Washington students test their drones in a big room.

Christopher Lum, a scientist at the University of Washington, helps students explore how drones can safely share the sky with regular aircraft. Lum explained why they test drones inside a building, “We need to register our aircraft and get permission to fly outside. That process can take months.”

At this time, Kansas State University is the only school with permission to offer unmanned aircraft flight classes to students outside. The FAA selected Kansas State University and 15 other universities to be part of a national research group.

Lum and some of his students recently moved their research to Australia. Australia has fewer rules limiting drones. A professor at Western Washington University also took his department’s drones to Canada for the same reason.

1.Degrees in UAS were created in several U.S. universities because of ________.

A. the increasing interest in the field

B. the increasing employment opportunities

C. the support from the government

D. the development of this technology

2.Why didn’t Handley think the drone program was a good idea at first?

A. Drones can be used for bad purposes.

B. The use of drones was very limited.

C. Few people can benefit from the program.

D. The university didn’t attach great importance to the program.

3.According to Lum, why does he teach flight classes inside a building?

A. It’s safer for the students.

B. It’s very expensive to register the aircraft.

C. It takes a very long time to get official permission.

D. He hasn’t got permission from the university.

4.What can we infer from the last two paragraphs?

A. Australia is promoting the use of drones.

B. Kansas State University is the first to offer a UAS degree.

C. Australia has fewer rules than Canada to control the use of drones.

D. The U.S. has more rules than Canada to control the use of drones.

Nowadays,cars have become a very common vehicle in our life.As the most important transport,cars have improved our modern life in many ways.However,cars also bring about so many problems for people,which should be given more attention than any time before.

Cars give people the ability to travel to any place they like.Many people begin to travel frequently.This helps people connect with each other better than before.A more obvious influence from cars is the large number of jobs that they create.Jobs in several fields open up thanks to cars,such as jobs in car factories,gas stations and highways. This is a huge positive influence on society because they greatly reduce the unemployment rate.

At the same time,the problems that cars cause seem to be more and more serious.A mass use of cars is bound to have some negative consequences.The widespread use of cars has led to serious traffic jams in cities.They have resulted in a reduction in the use of public transportation in many cities.The need to use and develop public transportation has been much discussed and confirmed.And also,car accidents create a number of injuries and deaths. There are hundreds of thousands of them worldwide every year.Gas let out from the engines of cars pollutes the air in cities around the world.Air pollution creates serious health problems and causes many people to die from it.It has become one of the most serious problems today.Efforts to develop pollution-free engines may be the final solution to this problem.

In conclusion,people should not only enjoy the benefits of cars,but also aim to deal with the problems cars have created.At the same time,the government should improve city traffic systems,encourage people to use public transportation,make efforts to improve road safety and encourage the usage of fuels that are low in pollutants.Only in these ways can the benefits of cars outweigh their harmfulness.
