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

What’s the capital of Australia? If you answer Sydney, you’re wrong, with travel website VirtualTourist.com (www.virtualtourist.com) coming up with a list of the six most surprising non-capital cities in the world.
1) New York City, New York
It may be king of the hill and the top of the heap (堆), but only figuratively (比喻地). NYC is not the country’s capital, which is Washington DC. Nor is it the state capital, an honor given to the upstate(北部地区的) town of Albany, which is also the birthplace of perforated (穿孔的)toilet paper.
2) Sydney, Australia
Although it is famous for its harbor and opera house, Sydney is not the capital. Canberra, which is just less than its one-hundred-year celebration, is actually the capital of Australia.
3) Rio de Janeiro, Brazil
It’s fun, exciting and has something for everyone, but that still doesn’t make it Brazil’s capital. While the city which is famous for the festival used to be the capital, Brasilia now takes that position.
4) Johannesburg, South Africa
Interestingly, South Africa has more than one capital city, none of which are Johannesburg. Divided by branch of government the capitals are: Bloemfontein, the capital of the judiciary (司法的), Pretoria, the capital of the administrative branch and Cape Town acting as the country’s legislative (立法的) capital.
5) Geneva, Switzerland
Neither this nor Zurich serves as the country’s capital. The attractive, quiet, UNESCO-recognized town of Bern holds this honor.
6) Timbuktu, Mali
Mysterious, exotic (异国情调的), and perhaps the country’s most recognizable name, it takes second place to the city of Bamako. Bamako considered the fastest growing city in Africa. It is also a world-famous center for music. Bamako is attracting famous singers to its local pubs where hometown artists play through the night.

D. Albany
