Getting rid of dirt, in the opinion of most people, is a good thing. However, the attitudes to dirt are always changing.
In the early 16th century, people thought that dirt on the skin was a means to block out disease, and washing off dirt with hot water could open up the skin and let ills in. A particular danger was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. The king of England did something similar in 1546. Thus began a long time when the rich and the poor in Europe lived with dirt in a friendly way. France’s Henry IV was famously dirty. Upon learning that a nobleman had taken a bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.
Though the belief above was long-lived, dirt has no longer been regarded as a nice neighbour ever since the 18th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have moved beyond science since World War II. Advertisements repeatedly sell the idea; clothes need to be whiter than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?
Attitudes to dirt still differ hugely nowadays. Many first-time parents nervously try to warn their children off touching dirt, which might be responsible for the spread of disease. On the contrary, Mary Ruebush, an American immunologist(免疫学家) , encourages children to play in the dirt to build up a strong immune system. And the latter position is gaining some ground.

So many of us are terrible at being terrible. As our children venture off to school, sports, dances and music lessons, we urge them: Just try something, keep practicing, you’re only a beginner. And yet, faced with our own failure, we become less confident, and quit altogether.

8 . 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. |
A.To stop and protect cars from running in the opposite direction. |
B.To set aside a wide, flat, clear space on either side of the road. |

C.Box-beam guardrails look like long metal boxes running between opposite cars. |

9 . As school starts this fall in Tununak, a tiny Eskimo community of Alaska, Teacher Ben Orr is planning to invite elderly storytellers into the classroom so his young students can learn and then write down traditional legends and knowledge of their disappearing culture. For Donna Maxim’s third-graders in Boothbay, Me., writing will become a tool in science and social studies as students record observations, questions and reactions about what they discover each day. In Eagle Butte, S.D., Geri Gutwein has designed a writing project in which her ninth-grade students exchange letters with third-graders about stories they have read. This year a few of her students will sit with Cheyenne women who tell tales as they knit together, their tradition becoming materials for today’s young writers.
Although these teachers are separated by thousands of miles, their methods of encouraging children to write spring from a common source: the Bread Loaf School. There, near Vermont’s Middlebury College, grade school and high school teachers give up part of their vacations each summer to spend six weeks brainstorming, studying and trading experiences as they try to design new methods of getting their pupils to write. Says Dixie Goswami, a professor who heads Bread Loaf’s program in writing: “We have nothing against ‘skill-and-drill’ writing curricula, except that they don’t work.” Instead, Bread Loaf graduates have created one inventive program to work together to cultivate student writers.
The Bread Loaf literature and writing program began in 1920 as a summer resort where English teachers studied for advanced degrees. Until the late 1970s most were teachers from schools for the upper class. Bread Loaf “was failing in its social responsibility,” says Paul Cubeta, a professor who has directed the program since 1965. “So we went looking in rural America for potential educational leaders.” Foundation funds were raised to help bear the cost for tuition and board. Over the past ten years nearly 500 rural instructors have studied there.
Many of the new ideas teachers took away from Bread Loaf seemed in danger of fading back home, remembers Cubeta. “We need to devise a way for them to go back with support for their projects and for each other.” One result was an idea called BreadNet: by setting up a network of word processors, Bread Loaf-trained teachers could instantly connect their classrooms.
