Professor Taiju Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age, and how the process of aging could be slowed down.
With a team of colleagues at Tokyo National University, he set about measuring brain volumes of a thousand people of different ages and varying occupations.
Computer technology enabled the researchers to obtain precise measurements of the volume of the front and side sections of the brain, which relate to intellect (智能) and emotion, and determine the human character. (The rear section of the brain, which controls functions like eating and breathing, does not contract with age, and one can continue living without intellectual or emotional faculties.)
Contraction of front and side parts—as cells die off—was observed in some subjects in their thirties, but it was still not evident in some sixty- and seventy-year-olds.
Matsuzawa concluded from his tests that there is a simple remedy to the contraction normally associated with age—using the head. The findings show in general terms that contraction of the brain begins sooner in people in the country than in the towns. Those least at risk, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing routine work in government offices are, however, as likely to have shrinking brains as the farm worker, bus driver and shop assistant. Matsuzawa’s findings show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. “The best way to maintain good blood circulation is through using the brain,” he says, “Think hard and engage in conversation. Don’t rely on pocket calculators.”

The total amount of packaging has increased by 12% between 1999 and 2005. It now makes up a third of a typical household"s waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard.
Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for burying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example.
But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But it is also applied to a wide range of consumer products, which often have far more packaging than necessary.
There are signs of hope. As more of us recycle, we are beginning to realize just how much unnecessary materials are collected. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.

D.the rapid growth of supermarkets |
A.means burning packaging for energy |
B.helps control the greenhouse effect |
C.is the solution to gas shortage |
D.leads to a waste of land |
A.Unpackaged products are of bad quality. |
B.Supermarkets care more about packaging. |
C.Other products are better packaged than food. |
D.It is improper to judge quality by packaging. |
A.Needless material is mostly recycled. |
B.Fighting wastefulness is difficult. |
C.People like collecting recyclable wastes. |
D.The author is proud of their consumer culture. |
Living away from home tends to be the toughest adjustment for first-year students. You may feel homesick in your first weeks or months. It can help to call, write, or email your parents and friends, making them know how you’re going. You can also talk with your roommates. As first-year students themselves, they’re probably experiencing many of the same fears and worries that you’re dealing with .
But what if you don’t get along well with your roommates?
In some cases, it can be a good thing if you and your roommates aren’t much alike. Different views on things may be helpful, so respect your differences no matter what.
If you and your roommates don’t get along well, it can help to find someone who you feel does understand you, which should be easy on a campus with so many people. Many schools have student organization nights where all of the campus clubs gather and promote their organizations, so you can meet people with the same interests there as you. You’ll also meet tons of people in class or in your dorm building.
As homesickness, painful throats, sprained (扭伤的) ankles and wisdom teeth that act up are common among college students, you should check out your student guidebook or your school’s website to find out information about the university health center.
If you think you cannot deal with your problems, make a stop at the school counseling (咨询)center. First-year troubles are something the counselors know well. You can get help there.

For many centuries, people used windmills to grind (磨碎) wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote (偏僻的) areas began to use them to produce electricity. This allowed them to have electric lights and radio. However, by the 1940s when electricity was available to people in almost all areas of the United States, windmills were rarely used.
During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means high costs. Today, there is a global movement to supply more and more of our electricity through the use of wind.

C.Grinding wheat into flour. | D.Pumping water from underground. |

B.it is one of the oldest power sources |
C.it was cheaper to create energy from wind |
D.the supply of coal and gas failed to meet ends |
A.The advantages of wind power. |
B.The design of wind power plants. |
C.The worldwide movement to save energy. |
D.The global trend (趋势) towards producing power from wind. |
