Directions: Read the following text carefully and then translate the underlined segments into Chinese. Your translation should be written clearly on ANSWER SHEET 2.

At our house, nobody gets more mail than Jake: catalogs, coupons, and offers to subscribe to magazines. (61) He is also urged to donate to worth causes and take advantage of some pretty incredible credit-card offers.

He ignores all of them. What do they expect? He's a dog.

(62)It all started when I used Jake's name as an assumed name on the Internet. in an attempt to protect what's left of my privacy. Before I knew it, junk was pouring in, proving once again that these days every move you make online can be, and often is, carefully watched and recorded by people who don't know you from your dog--everyone from ad and insurance agencies to nonprofit groups and even the dreaded telemarketers. And let's not forget the more, shall we say, unscrupulous characters.

(63) We've all heard horror stories about people whose identities, in the form. of credit card or Social Security numbers, were assumed by crooks.Identity theft is one of the fastest-growing crimes around.

Even if you never buy anything online, your privacy can be compromised by Web "cookies." A cookie is a small file that a Web site stores on your computer containing information it can use to "recognize" you if you return to that site.

Most cookies pose little risk to privacy on their own. The problem comes when others get hold of your cookies. In a highly publicized case earlier this year, DonbleClick Inc planned to cross reference consumer cookie data with information from a marketing database, such as name, address and credit card purchase history. (64) Seen as an unethical violation of consumers' privacy, a lawsuit followed. DoubleClick backed off the plan. for now.

In the meantime, other threats to your cyber privacy still exist. Example:

Anyone who knows where to look can buy stolen credit card numbers in chat rooms, and spends up every penny on your card in minutes.

(65) As new technologies bring out the creativity in crooks, your best bet may be plain old-fashioned vigilance. Keep track of each penny, balance your checkbook and follow up on discrepancies in your statements immediately. However much the world change, it still pays to be your own watchdog.

第10题

Owing to the insufficient gas supply in the United States, the gas price has dramatically risen. The new gas price reality and the policy decisions it may trigger will undoubtedly lead to critical financial implications for some individuals or companies, but the situation can hardly be termed a "national crisis" or even a "shortage". What is true is that buyers—particularly those in the chemical industry and in independent power generation will not be able to acquire the quantity of gas they wish at the prices they wish to pay, or even at prices that will allow them to remain competitive in their markets, particularly during peak demand seasons.

Over the next year or two, the result will be higher, and more volatile prices, to be sure, but there are market-driven adjustment mechanisms even in the short term, e.g., more electric power from coal and oil, reduced production of domestic chemicals, and a commensurate substitution of imports. Consumers and companies will feel the economic pinch of higher prices; particularly, if we experience an exceptionally hot summer and a winter, when average temperatures were 20% colder than the year before in the Northeast. Still, the United States faces neither the specter of economic recession—at least not solely due to gas prices—nor of freezing families unable to 'obtain gas to heat their homes.

Given this new price plateau, demand adjustments will also take place and vary across regions of the United States and across industries, with power generation and chemicals perhaps the most affected. Some in those industries may find that their facilities are no longer financially viable at the new price plateau, and there will likely be another round of industrial restructuring not unlike others that have resulted from international differences in resource and labor costs—lest we forget, natural gas is still abundant and very low cost in other countries such as Trinidad, Qatar, and Iran, just as labor is abundant and low cost in China, Indonesia, and parts of Latin America.

From a policy perspective, the United States needs to carefully evaluate a series of trade-offs between environmental concerns and economic growth. The gas price experiences of the last two years are the first real tastes of the economic costs of a gas-based environmental strategy. Evaluating these trade-offs needs to be done with a level head and a clear understanding of those trade-offs.

What is the main topic of the article?

A.American economy is strongly hit by the high prices of gas.

B.American economy is affected by the high price of gas, but it is not a crisis.

C.American economic policy is a failure.

D.The prices of gas will rise in the following years.
