1 . What are those short metal fences by the side of the road? They don’t look like much. But they do a big job.
People who design highways would always like to have a wide, flat, clear space on either side of the road. That way, if a car goes off the road, it can stop safely.
But in some places, that’s just not possible. That’s when they put up a guardrail. These short railings are designed to stop cars from running into something more dangerous, without damaging the car too much.
The type of guardrail they put up depends on the road. A weaker guardrail may let the car go farther off the road, but does less damage to the car. A strong guardrail stops a car in a short distance, but the car suffers more damage.
![]() | Jersey barriers are made of concrete. They are often placed down the center of a road to separate cars going in opposite directions. Jersey barriers are also used around construction zones. They are cheap to make and easy to move around. | ![]() | A box-beam guardrail looks like a long metal box running between posts. Box-beam guardrails are very strong, but expensive. They are used mostly where it’s important to stop cars quickly. You might see one in the middle of a road to keep cars from going into oncoming traffic. |
![]() | A strong-post W-beam guardrail has short, thick posts set close together. This common guardrail is used where it’s important to stop a car quickly to save lives, such as where a cliff is right next to the road. It gets its name from the fact that if it’s cut in half, the rail looks like a sideways W. | ![]() | A weak-post W-beam guardrail has posts that are thinner and farther apart. Why would anyone want to make a guardrail with weak posts? A weak-post guardrail will stop a car more slowly than a strong-post guardrail. The more gradually a car slows down, the less likely its riders will be hurt. A weak-post guardrail can be used where there is more space to slow a car down. |

7 . Although many companies offer tuition reimbursement (偿付), most companies reimburse employees only for classes that are relevant to their positions.
One good reason for giving employees unconditional tuition reimbursement is that it shows the company’s dedication to its employees and it is important for a company to demonstrate to its employees that it cares. The best way to do this is to make investments in them.
Though unconditional tuition reimbursement requires a significant investment on the employer’s part, it is perhaps one of the wisest investments a company can make.
A.In this way, companies will have more productive employees. |
B.In today’s economy, job security is a thing of the past and employees feel more and more expendable. |

9 . For four lonely years, Evelyn Jones of Rockford, Illinois, lived friendless and forgotten in one room of a cheap hotel. “I wasn’t sick, but I was acting sick,” the 78-year-old widow says, “Every day was the same. I would just lie on my bed and maybe cook up some soup.” Then, six months ago, she was invited to The Brighter Side -- Rockford’s day care center for the elderly. Every weekday morning since then, she has left her home to meet nine other old people in a church for a rich program of charity work, trips, games, and -- most important of all -- friendly companionship.
Just a few years ago, there were few choices for the elderly between a normal life in their own homes and being totally confined in nursing homes. Many of them were sent to rest homes long before they needed full-time care. Others like Mrs. Jones were left to take care of themselves. But in 1971, the White House Conference on Aging called for the development of alternatives to care in nursing homes for old people, and since then, government-supported day-care programs like The Brighter Side have been developed in most big American cities.
“This represents a real alternative to the feared institution and makes old people believe they have not left the world of living”, says Alice Brophy, 64, director of New York City’s Office for the Aging, “They do well at the centers, and I hate it when people describe us as elderly playpens.” New York’s 138 centers encourage continuing contact for the aged with the community’s life. The centers serve more than 15,000 members, and volunteer workers are always looking for new ones. If someone doesn’t show up at the center for several days in a row, a worker at the center calls to make sure all is well. And although participation in the center is free, those who want to can pay for their lunches.
No normal studies have been made of these centers for the elderly, but government officials are enthusiastic. In the future, the Public Health Service will do a study to decide if the programs can receive federal Medicare money. And the old people themselves are very happy with the programs. “There is no way”, says Evelyn Jones, smiling at her new companions at the Brighter Side, “that I will ever go back to spending my day with all those loses at the hotel.”
