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.
B. are likely to sell well in the future.
C. are mainly used in the United States
D. won't be used in the London Olympics
B. Hydrogen buses
C. The FCX Clarity
D. Filling stations
B. In Hamburg
C. In London
D. In Los Angeles
B. hydrogen vehicles fueled by water will be very expensive
C. Honda will mass-produce the FCX Clarity by 2012
D. Honda produced its first hydrogen car in 1989

| Advertising is a form of communication that uses all kinds of media, and is visible everywhere these days. Typical customers of advertising companies are other companies, or businessmen, who want to persuade potential customers to buy more of what they make or sell. But there are other kinds of customers. Some organizations spend large sums of money on advertising a political party or other group that sells what is not, strictly speaking, a product or service. Such non - profit organizations are not typical advertising customers, and they prefer ways of spreading knowledge, changing attitudes, and improving society. Many advertisements are designed to increase sales of products and services by either improving brand image or, in the case of non - profit organizations, expressing ideas. In order to achieve th~s, advertisements will often pass on truthful information while delivering their messages. Every major medium is a means of delivering these messages, including television, radio, cinema, magazines, newspapers, video games, the Internet and billboards (大幅广告牌). Advertising will usually be created and. placed by an advertising agency on behalf of company or other organization. Spending on advertising has increased greatly in recent years. In 2006, spending was estimated at $155 billion in the United States and $385 billion worldwide; the latter is expected to reach more than $500 billion by 2010. While advertising can be seen as a necessity for economic growth and social development, it is not without social costs. Advertisement emails and other forms of junk mail have become so popular that ~they have become a major burden to users of I nternet email services, as well as a financial burden on Internet email service providers.
