If you want stay young, sit down and have a good think. This is the research finding of a team of Japanese doctors, who say that most our brains are not getting enough exercises—and as a result, we are ageing unnecessarily soon.
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 ageing could be slowed down.
With a team a colleague (同事) 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 (精确的) 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 facilities.
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 workers, bus drivers and shop assistants.
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 team of doctors wanted to find out______.
A.how to make people live longer
B.the size of certain people's brains
C.which people are most intelligent
D.why certain people age sooner than others

“Do you think I can stay to become noting to you? So you think I am an automation?—a machine without feelings? And can bear to have my morsel of bread snatched form. my lips and my drop of living water dashed from my cup? Do you think, because I am poor, obscure, plain, and little, I am soulless and heartless? – You think wrong! – I have as much soul as you—and full as much heart! And if God had gifted me with some beauty, and much wealth, I should have made it as hard for you to leave me, as it is now for me to leave you. I am not talking to you now through the medium of custom, conventionalities, or even of mortal flesh: -- it is my spirit that addresses your spirit; just as if both had passed through the grave, and we stood at God’s feet, equal – as we are!”

听力原文:Donating blood plasma has always been a noble pursuit to help those in need. Since last September, there has been an upsurge in blood donations, as the need has become more emphasized and more empathized. But if you've had a tattoo or piercing within the last year, you will more than likely be turned away from any blood bank.
When you go to a blood bank to give plasma, they ask you a series of questions to determine if you are eligible to donate. Obviously, they don't want to risk accepting contaminated blood, so they will ask about your sexual history, current health status and other related questions, including whether or not you have gotten a tattoo or piercing within the last 12 months.
All blood that is donated is screened for disease such as HIV, Hepatitis, Syphilis and other common blood- born ailments.
However, it goes without saying that it is a waste of the blood bank's and the donor's time to harvest blood that is tainted and thus worthless.
So, in order to avoid wasted time, they ask these questions to screen the potential donor. And although even I would be quick to say that tattooing and piercing are much safer than some medical professionals like to indicate, there is still always a chance of getting and carrying a disease unknowingly from a tattoo or piercing, especially Hepatitis. That has been the object of many heated arguments and stringent regulations.
If you should happen to contract a disease from a tattoo or piercing, it should show up in a screening after 12 months, which is the reason for the waiting period. Yes, maybe it's a little over-precautious, but would you want to be the one on the receiving end of dirty blood? If there, is even a chance, it is better to be safe than sorry.
