Mail carriers will be delivering some good news and some bad news this week.

The bad news: Stamp prices are expected to rise 2 cents in May to 41 cents, the Postal Regulatory Commission announced yesterday. The good news: With the introduction of a “forever stamp,” it may be the last time Americans have to use annoying 2-or-3-cent stamps to make up postage differences.

Beginning in May, people would be able to purchase the stamps in booklets of 20 at the regular rate of a first-class stamp. As the name implies, “forever stamps” will keep their first-class mailing value forever, even when the postage rate goes up.

The new “forever stamp” is the United States Postal Service’s (USPS) answer to the complaints about frequent rate increases. The May increases will be the fifth in a decade. Postal rates have risen because of inflation (通货膨胀), competition from online bill paying, and the rising costs of employee benefits, including healthcare, says Mark Saunders, a spokesman for USPS.

The USPS expects some financial gain from sales of the “forever stamp” and the savings from not printing as many 2-or-3-cent stamps. “It’s not your grandfather’s stamp,” says Mr. Saunders. “It could be your great-grandchildren’s stamp.”

Other countries, including Canada, England, and Finland use similar stamps.

Don Schilling, who has collected stamps for 50 years, says he’s interested in the public’s reaction. “This is an entirely new class of stamps.” Mr. Schilling says. He adds that he’ll buy the stamps because he will be able to use them for a long period of time, not because they could make him rich — the volume printed will be too large for collectors. “We won’t be able to send our kids to college on these,” he says, laughing.

The USPS board of governors has yet to accept the Postal Regulatory Commission’s decision, but tends to follow its recommendations. No plans have been announced yet for the design of the stamps.

The main purpose of introducing a “forever stamp” is ______.

A. to reduce the cost of printing 2-or-3-cent stamps

B. to help save the consumers’ cost on first-class mailing

C. to respond to the complaints about rising postal rates

D. to compete with online bill paying

By saying “It could be your great-grandchildren’s stamp”, Mr. Saunders means that forever stamps ________.

A. could be collected by one’s great-grandchildren

B. might be very precious in great-grandchildren’s hands

C. might have been inherited from one’s great-grandfathers

D. could be used by one’s great-grandchildren even decades later

Which of the following is true according to the passage?

A. The investment in forever stamps will bring adequate reward.

B. America will be the first country to issue forever stamps.

C. The design of the “forever stamp” remains to be revealed.

D. 2-or-3-cent stamps will no longer be printed in the future.

What can be concluded from the passage?

A. With forever stamps, there will be no need to worry about rate changes.

B. Postal workers will benefit most from the sales of forever stamps.

C. The inflation has become a threat to the sales of first-class stamps.

D. New interest will be aroused in collecting forever stamps.

Monty Roberts owns a horse ranch（牧马场） in San Ysidro. He told us his story. As a senior, he was asked to write a 36 about what he wanted to be and do when he grew up.

That night he wrote a seven-page paper 37 his goal of someday owning a horse ranch. He wrote about his dream in great 38 and he even drew a diagram of a 200-acre ranch, showing the 39 of all the buildings.
He put his heart into the 40  and the next day he handed it in to his teacher. Two days later he received his paper back. On the front page was a large red F with a note that   41 , ‘See me after class.’
The boy with the dream went to see the teacher after class and asked, ‘Why did I 42 an F?’
The teacher said, ‘This is an 43 dream for a young boy like you. Owning a horse ranch requires a lot of money. There’s no 44 you could ever do it.’ Then the teacher added, ‘If you will 45 this paper with a more realistic goal, I will reconsider your grade.’”
The boy went home and 46 it. He asked his father what he should do. His father said, ‘Look, son, you have to 47 your own mind on this. However, I think it is a very 48 decision for you.’
Finally, after sitting with it for a week, the boy turned in the 49  paper, making no changes at all. He stated, ‘You can keep the F and I’ll keep my 50 .’
Monty now owned a 200-acre ranch. He had 51 his plan for a 4,000-square-foot house.
Two summers ago that same school teacher brought 30 kids to camp out on his ranch for a week. When leaving, he said 52 , ‘Look, Monty. When I was your teacher, I was something of a dream 53 . During those years I stole a lot of kids’ dreams. 54  , you had enough perseverance not to give up on yours.’”
Don’t let anyone steal your dreams. 55 your heart, no matter what.

There are various ways in which individual economic units can interact with one another. Three basic ways may be described as the market system, the administered system, and the traditional system.
　　In a market system individual economic units are free to interact among each other in the marketplace. It is possible to buy commodities from other economic units or sell commodities to them. In a market, transactions may take place via barter or money exchange. In a barter economy, real goods such as automobiles, shoes, and pizzas are traded against each other. Obviously, finding somebody who wants to trade my old car in exchange for a sailboat may not always be an easy task. Hence, the introduction of money as a medium of exchange eases transactions considerably. In the modern market economy, goods and services are bought or sold for money.
　　An alternative to the market system is administrative control by some agency over all transactions. This agency will issue commands as to how much of each good and service should be produced, exchanged, and consumed by each economic unit. Central planning may be one way of administering such an economy. The central plan, drawn up by the government, shows the amounts of each commodity produced by the various firms and allocated to different households for consumption. This is an example of complete planning of production, consumption, and exchange for the whole economy.
　　In a traditional society, production and consumption patterns are governed by tradition; every person’s place within the economic system is fixed by parentage, religion, and custom. Transactions take place on the basis of tradition, too. People belonging to a certain group or caste（阶级） may have an obligation to care for other persons, provide them with food and shelter, care for their health, and provide for their education. Clearly, in a system where every decision is made on the basis of tradition alone, progress may be difficult to achieve. An inactive society may result.
