sea-level rise is now unavoidable (不可避免的), it will happen faster than most of us thought, and it will
go on for a very long time.
Even if greenhouse gas emissions (排放) stopped tomorrow, the oceans would continue to become
larger as they get warm. The climate scientists estimate that sea-level rise may be in the range of 1 to 2
meters by 2100, with a small risk of an even greater rise.
For many islands and low-lying regions, even small rises will cause disasters. But for most countries,
the problem is what has been built on that land: New York, Sydney and Tokyo, to mention just a few
cities. Unless something can be done, great areas of urban network will disappear under the waves. It
will take a great engineering effort to protect these cities-an effort that may be beyond economies that
have been brought to their knees.
None of this means we should fear, and stop trying to forbid emissions. But together with these efforts,
we need to start acting now and we must stop building in danger zones.
Billions of dollars are being spent on constructing homes, offices and roads in vulnerable (脆弱的)
coastal areas. For instance, the skyscrapers of Shanghai are being built on land that is mere 4 meters
above sea level on average, and they are sinking under the weight of the buildings. Therefore, planning
for new coastal developments is to go against reality. If we want to build a lasting heritage for our children,
we should do so on the plentiful land that is in no danger from the sea. It is one of the effective ways to
slow down climate change, and we should be acting on it now.
B. temperature change of the oceans
C. vulnerable coastal area
D. fast urban development and expansion
B. modem cities are usually built along the coastline
C. the coastline is very important for modem countries
D. climate change can do harm to economies
B. people have lost confidence in their economies
C. economy development has made climate change worse
D. protecting the cities may cost more than what has been obtained
B. stop building skyscrapers in big cities like Sydney and Tokyo
C. build cities on the land free from the danger of sea-level rise
D. be aware of the danger of greenhouse gas emissions into the ocean

| 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.
