There are two methods by which hydrogen (氢) can be used to power cars. The first way is to use hydrogen to drive the engine, in much the same way as many cars use gas. The second method is to use the reaction of hydrogen with oxygen in a battery, making the car a kind of electric one.
The dream of producing hydrogen in the car while driving along by electrolyzing(电解)water is a long way off, so we are still at the period of batteries and filling the tank with hydrogen gas. This is the difficulty for potential car users and producers. There are only sixteen hydrogen filling stations in Los Angeles and none in 99% of other cities worldwide.
Indeed, some of the big name automobile producers have pulled out of the race to put the first practical hydrogen car on the streets. Ford and GM have announced that they are pulling out in America and so has Renault in France.
However, the Japanese companies are pressing on. In fact, Honda introduced its first hydrogen fuel cell car in 1999. They are now producing second generation hydrogen car known as the FCX Clarity. Guess where they are available for sale? In only one city because of its filling stations.
Honda thinks that they could go into full-scale production of the FCX Clarity by 2020 if the world is prepared for them by then.
Then there are hydrogen-powered buses in several European cities including Amsterdam, Barcelona, Hamburg, London, Luxembourg and Madrid. Lotus, the makers of London taxis, have announced that they propose to manufacture hydrogen-powered taxis in time for the London Olympics.
So, the hydrogen vehicle is out there and the numbers will be growing fairly soon. The buses go back to their bus station, where an electrolyzing machine changes water into fuel for them to fill up on and the same will be the case for many of London’s taxis.
Unfortunately, getting fuel is not the only difficulty for the average motorist, a number of these vehicles cost about $300,000 each.

查看习题详情和答案>>Officials say the islands of Tokelau in the South Pacific Ocean have become the world's first territory totally powered by the sun.The move is expected to save money and ease the environmental burden of depending on imported fossil fuels.
Tokelau's three main atolls(环状珊瑚岛),or islands,now have enough solar capacity to meet all of their electricity needs.Until now.Tokelau has been 100%dependent on diesel (柴油) for producing electricity.That has burdened the country with heavy economic and environmental costs.
The three atolls of Tokelau are about halfway between New Zealand and Hawaii and are administered by New Zealand.
Each atoll received its own solar power grid (电网)system.New Zealand officials estimated the cost of the project to build the three solar grids at around seven million dollars.The last of the grids has been completed.
It is estimated that oil imports make up to 30%of national income in some parts of the Pacific.The move to solar power could save Tokelau about one million dollars a year.Tokelau will now be able to spend more on social programs to help its citizens.
Other South Pacific islands are attempting similar projects.The island nations of Samoa and Tuvalu are aiming to get all of their electricity from renewable sources by 2020.The Cook Islands plans to start moving to solar panels and wind turbines.And most houses in the South Pacific groups of islands will begin to use solar water heaters.
East Timor's government has promised that no households in the capital,Dili,would be using firewood for cooking by 2015.It also says 50%of the country's electricity will come from renewable sources by the end of the decade.
New Zealand Foreign Affairs Minister Murray McCully says the country will hold a Pacific energy summit in March this year.He said the meeting would build on the success of clean and affordable energy solutions for Tokelau,Tonga,and the Cook Islands.

A.the country's heavy economic and environmental burden

C.the country's excellent location in the Pacific
D.New Zealand's administration and strong support
72.We can know Tokelau used to spend about dollars on oil imports every year.
A.seven million B.one million
C.three million D.four million
73.What can we learn from the text?
A.Some houses in Tokelau still lack solar capacity.
B.Tokelau has partly depended on fuel electricity.
C.Tokelau doesn't use imported diesel to produce electricity now.
D.Not every atoll has its own solar power grid system in Tokelau.
74.All the island nations except will get all of their electricity from renewable sources by 2020.
A.Samoa B.Tuvalu C.Tokelau D.East Timor
75.The text is mainly about .
A.Tokelau's solar power project
