An Australian company, Smart Car Technologies, has developed a system that lets drivers know when they’re speeding. When the technology becomes commercially available, it could help lead-footed drivers avoid tickets and also save lives. The company that developed the product hopes to convince Australian government agencies to put the technology into use in their automobile fleets.
The product, called Speed Alert, links real-time location data and speed obtained with the help of GPS to a database of posted speed limits stored in a driver’s PDA or programmable mobile phone. The setup of the product does not need to be hooked up to a car’s speedometer. In fact, it is entirely portable. It will also work with newer phones and PDAs that have built-in GPS receivers. If a driver exceeds the speed limit, the speed is shown and an alert sounds.
Michael Paine, an Australian vehicle design engineer and traffic safety consultant, was hired to analyze the product. He told Live Science that his colleagues in the road safety field are “very enthusiastic” about what they’re now calling “intelligent speed alert.” Other research, according to Paine, shows that 40 percent of all traffic deaths involve speeding. There is also a potentially controversial future use: “Since the system is so portable, it would be easy to make it a requirement for teenage drivers to always use a speed alert device when driving,” Paine said. “The system even has the capability to record speeding violations, so parents can monitor their teenage drivers.”
The product will soon go on sale in Sydney.
1. What’s the purpose of the new product?
A. To inform us of the new car system. B. To introduce some improvement in cars.
C. To limit certain drivers to safe driving. D. To popularize the built-in car system.
2.The second paragraph mainly talks about .
A. the project of the built-in product B. why the system becomes popular
C. the functions of GPS in cars D. how the product is programmed
3.Which of the following is true of Speed Alert according to Michael Paine?
A. Most of the traffic deaths can be avoided. B. Speeding violations can be easily found out.
C. The system will excite some teenage drivers. D. The product will not be available for adults.
4.What can be the best title of the passage?
A. Speed Alert and Its Future Use. B. Progress in Car-making Science.
C. Warning for Adventurous Drivers. D. New In-Car Device against Speeding.

Car companies are developing vehicles that will plug into electric sockets, ust like many laptops, digital cameras, cell phones and Mp4 do. Called “plug-in vehicles”, these cars will get most of their power from electricity. Their drivers won't have to stop at gas stations as often as usual.
The technology is more than just cool. In our car-filled world, plug-in vehicles could reduce the amount of gas we use, which keeps rising in cost now and then. Besides, driving around in these vehicles may even help the environment. Gas-burning cars produce a lot of greenhouse gas, which causes global warming.
The first company-produced plug-in vehicles could hit the roads by 2020. But engineers still have a lot of work to do to make the technology practical and inexpensive.
Batteries are the biggest challenge. In the plug-in-vehicle world,Li-ion(锂离子)batteries are getting the most attention. These batteries can store a large amount of energy in a small package, and they last a longer time between charges. Li-ion batteries can fit laptops, cell phones, heart instruments and other similar pocket ones.
But because cars are so big and heavy, it would still require a suitcase-sized Li-ion batteries to power about 12km of driving. What's more, the batteries are much expensive.
“A car filled with batteries could go a long distance,” says Ted Bohn, an electrical engineer in Chicago. “But it couldn't pull any people, and it would cost $100,000.” So researchers need to work out how to make batteries smaller and cheaper, among other questions.
“The answers don't exist yet, ” Bohn says, “As a kid, I thought someone someplace knows the answer to everything. All of these questions haven't been decided. That's what engineering is about-making a guess, running tests and getting fine results.”
1.According to the passage, the main problem of the new car is ______________.
A. the developing B. the speed
C. the appearance D. the batteries
2.Which is true according to the passage?
A. The “plug-in vehicles” will use electricity completely as driving power.
B. The new technology will help protect our environment.
C. The technology of using electricity as driving is quite practical now.
D. The biggest challenge of the new technology is that it will cost us more energy.
3.How does Bohn feel about the future of the technology according to the last paragraph?
A. Confident B. Puzzled.
C. Worried. D. Disappointed.
4.According to the passage, the new technology is facing the problems except that_______.
A. the new technology cannot come into use at present
B. the cost of the new technology is quite high
C. the government won't support the technology
D. the size of the batteries is too big at present

Terrafugia Company has said that its flying car, named Transition, has successfully finished a 37- second test flight
On March 5, 2009, at Plattsburgh International Airport in New York. It was piloted by Phil Meteer, the company's chief pilot.
Transition is a two-seat airplane that can take off and land at airports as well as drive on roads.
The company said that the flying car can travel at speeds up to 115 mph for 450 miles in the air, drive at highway speeds on the ground, and fold up(折叠) to fit in a garage (车库) 81 inches wide, and 80 inches high.
This could be used in hospitals to transport patients so as to avoid road traffic. It may start running on wheels, and when it gets to traffic lights it can fly overhead the lights and keeps its way forward. So it’s good news to avoid traffic problem and the traffic accidents.
But some people say this is a going airplane rather than a flying car, at least on the appearance. Anyway, we are happy for scientific-technical progress, what a fantastical world in the near future!
1. This kind of new machine is made by ______.
A.Phil Meteer

An American company has built a new drone(无人机)that could improve the speed of deliveries(送交的货).
The drone is very different from other unmanned aircraft.It is made almost completely out of cardboard and has no motor.It can be packed with materials and sealed up with tape.
Because the drones do not have a motor,they are designed to be dropped from airplanes.Hundreds of drones could be sent out at once.Then they could be automatically guided to where they are supposed to go.The company says these drones could then complete deliveries to different places over an area covering hundreds of kilometers. The drones look bigger than the paper airplanes we used to make as kids.But this light flyer is not a toy.It is aerodynamically designed and equipped with a small computer,a battery and sensors to guide it to the ground.
The drones are being developed by Otherlab—a technology research company in San Francisco,California.It calls the drone a "Sky Machine."
The company says it can travel about 150 kilometers at speeds up to 88 kilometers an hour.Now,it can carry materials weighing up to one kilogram,but future models are expected to carry larger loads.
One of the drone's main advantages is that it does not have a heavy motor or large battery.This allows more room for materials and makes the drone cost less to build and operate.
The Otherlab development team has called its invention the "Ikea of drones."This is because it is packaged similarly to products from the Swedish furniture maker Ikea.The drone arrives as flat pieces of pre-cut cardboard that can be quickly and easily put together.
The technology that guides the drone can make it land within 10 meters of its target,according to Otherlab. Unlike other drones,even a crash landing is acceptable.The company says the drones can also be reused.
Once the drone completes its delivery,it can be thrown away and the cardboard material will likely break down within a few months.
The company has received money from the U.S. Department of Defense to carry out research on the drones.The money came from the Defense Advanced Research Projects Agency.The agency is attempting to find the best delivery vehicles that can disappear after their missions are complete.The U.S. military has a need for delivery drones.But it wants to simplify and lower the cost of using them.Otherlab's Sky Machines are an attempt to fill that need.
Military drones can also be stolen and studied by others if found after use.Before they can truly disappear,the electronic materials inside must also somehow disappear.Researchers are still working on ways to get the technology itself to self-destruct.
1.What does Paragraph 3 mainly talk about?
A. Why the new drone is invented.
B. What the new drone is equipped with.
C. How can the new drone get to the ground.
D. Why the new drone is designed like paper airplanes.
2.Why is the invention called the "Ikea of drone"?
A. Because it's a product made by Ikea.
B. Because it uses the idea from Ikea.
C. Because it's built at a low cost like furniture of Ikea.
D. Because it's made up of pre-cut cardboard.
3.Which of the following statements is the advantage of the new drone?
A. It can land near its target.
B. It has a light motor inside.
C. A crash landing is not acceptable.
D. Its load weighs far more than one kilo.
4.What about Otherlab's Sky Machines can be inferred from the last two paragraphs?
A. They have been built by the US military.
B. Research is being carried out on their improvement.
C. They are now often stolen and studied by others after deliveries.
D. The electronic materials inside will destroy themselves after use.
