Five years ago, when I taught art at a school in Seattle, I used Tinkertoys as a test at the beginning of a term to find out something about my students. I put a small set of Tinkertoys in front of each student, and said:"Make something out of the Tinkertoys. You have 45 minutes today - and 45minutes each day for the rest of the week."

   A few students hesitated to start. They waited to see the rest of the class would do. Several others checked the instructions and made something according to one of the model plans provided. Another group built something out of their own imaginations.

   Once I had a boy who worked experimentally with Tinkertoys in his free time. His constructions filled a shelf in the art classroom and a good part of his bedroom at home. I was delighted at the presence of such a student. Here was an exceptionally creative mind at work. His presence meant that I had an unexpected teaching assistant in class whose creativity would infect(感染) other students.

Encouraging this kind of thinking has a downside. I ran the risk of losing those students who had a different style of thinking. Without fail one would declare, "But I'm just not creative."

"Do you dream at night when you're asleep?"

"Oh, sure."

"So tell me one of your most interesting dreams." The student would tell something wildly imaginative. Flying in the sky or in a time machine or growing three heads. "That's pretty creative. Who does that for you?"

"Nobody. I do it."

"Really-at night, when you're asleep?"

"Sure."

"Try doing it in the daytime, in class, okay?"

How to Protect Your Ears

    You and your friends are leaving a concert on a Friday night. When you get outside, your ears are ringing. You have to shout to be heard. {#blank#}1{#/blank#} So no harm done…right?

    Not quite. Temporary buzzing may be easy to ignore, but repeated exposure to loud noise will eventually cause serious— and irreversible(无法治愈的)—hearing loss. A new study conducted by researchers at Brigham and Women's Hospital in Boston shows that one in five people between the ages of 12 and 19 are experiencing slight hearing loss, and one in 20 have mild hearing loss. {#blank#}2{#/blank#}

    But the good news is that there plenty of ways you can protect your ears from further damage — and still listen to the music you love:

    Ask around. Put your earbuds in or your headphones on, and then ask a friend next to you whether or not he or she can hear what you're listening to. {#blank#}3{#/blank#} Turn it down.

    Buy noise-canceling headphones. A pair of earbuds or headphones that fits comfortably will limit outside noise so that you can hear your music better at lower volumes.

    Take breaks. {#blank#}4{#/blank#} So when listening to music, take your headphones off for 15 or 20 minutes and let your ears enjoy the quiet.

    {#blank#}5{#/blank#} You can buy a cheap pair at any drugstore as an easy way to lower volume at concerts — or while playing or practicing your own music — without changing the quality of the sound.

A. Use earplugs.

B. Keep the volume below 70 percent.

C. If the answer is yes, your music is too loud.

D. Like every other part of your body, your ears need rest.

E. But by morning, your hearing is totally back to normal.

F. Unfortunately, there's no way to get back hearing you've already lost.

G. The exposure to noise is louder and longer than in any previous generation.

    Shlander is a man from space. He thinks the people and things on the earth are very strange. He is now writing a letter to his friend at home. Here is part of his letter. Read it and answer the questions.

    Now I am in a strange world. It is very nice. There are many new things here. There are many earth monsters (怪物) here, too. The earth monsters look very funny. They have just one head, two arms and two legs. They have thin black strings(细绳) on their heads. Some earth monsters have brown or yellow strings. The earth monsters have a hole in their faces. Every day, they put nice things and balls from the trees into the hole. They put water into the hole, too. The earth monsters do not walk very fast. They move from place to place in tin boxes.

    At night, the earth monsters like to look at a square window box. This box has very small earth monsters in it.

    Teenagers who spend hours in front of the television may have a poorer diet as young adults.

    A study, which included nearly 1,400 high school students, found those who watched TV for five hours or more per day had less healthy diets than peers(同龄人) five years later. Why does this happen? Should the parents take any measures?

    On the one hand, people who spend a lot of time in front of the TV, especially teenagers, may snack more, and that may affect their long-term diet quality.

    On the other hand, TV ads for fast food, sweets and snacks tempt teenagers to eat more of those foods. And TV time might also replace exercise time for some kids.

    Lead researcher Dr. Daheia J. Barr-Anderson, of the University of Minnesota in Minneapolis, told Reuters Health a clear correlation between TV time during high school and diet quality in young adulthood. While the heaviest TV viewers were eating the most junk food, those who'd watched less than two hours per day had the highest intake(吸收) of fruits, vegetables, whole grains and high-calcium food. In her opinion, parents should limit and monitor TV viewing.

    As far as I am concerned, children should watch no more than two hours of television per day. And parents should set a good example by eating right, being physically active and curbing their own TV time.

    Early birds-people who feel most energetic in the morning-tend to make healthier food choices throughout the day than night owls(夜猫子) , according to a new study.

    "Evening types had more irregular meal times," notes study author Mirkka Maukonen, studying human nutrition and obesity(肥胖) in Finland.

    Her study focused on people's risk of heart disease and their eating habits. Participants described when and what they had eaten during the past two days.

Maukonen's team then looked at l,854 people's lifestyle. After analyzing the data, the researchers found that both morning and evening people consumed approximately the same number of calories over a whole day.  However, night owls tended to eat their meals later than early birds. Before 10:00 am, night owls consumed less food than early birds. More of their calories came from sugar. After 8:00 pm, the night owls ate more sugar and fat. Meanwhile ,early birds ate more protein during both the morning and the evening hours.

    "Night owls tend to be less healthy than early risers," notes Courtney Peterson who studies diet and meal timing. "They are more likely to get heart disease or cancer. The fact that night owls tend to eat more junk food probably plays a role," Peterson says. "Other factors(因素) also can ruin a night owl's health. Night owls generally sleep worse," says Peterson. "Poor sleep has been linked to unhealthy food choices. "

    Peterson and Maukonen say night owls tend to have poor eating habits. But that doesn't necessarily mean that being a night owl makes a person a poor eater. It could be the reverse- eating poorly could affect people's sleep habits.

"The new findings should serve as a wake-up call to night owls. For them, the new results should encourage paying attention to healthier lifestyle choices," says Maukonen. 28. How did Maukonen do research about people's risk of heart disease?
