1. Wearing a seat belt saves lives; it reduces your chance of death or serious injury by more than half.

　　2. But it will be the driver’s responsibility to make sure that children under 14 do not ride in the front unless they are wearing a seat belt of some kind.

　　3. However, you do not have to wear a seat belt if you are reversing your vehicle; or you are making a local delivery or collection using a special vehicle; or if you have a valid medical certificate which excuses you from wearing it.

　　4. Remember you may be taken to court for not doing so, and you may be fined if you cannot prove to the court that you have been excused from wearing it.

　　5. 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 he slowed down.

　　6. 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.

　　7. 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.

　　8. 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.

　　9. The findings show in general terms that contraction of the brain begins sooner in people in the country than in the towns.

　　10. 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.

　　1、系好安全帶能夠挽救性命，它能將喪生和重傷的概率減少一半以上。

　　2、但是司機有責任確保14歲以下的孩子不要坐在前排，除非他們系好了安全帶。

　　3、當然，如果有以下情況你可以不系安全帶：你在倒車時，或者你用一種特殊交通工具進行當地的貨物運送、收集時，或者你有合法的醫學證明你不能系安全帶時。

　　4、注意你如果不這么做(系安全帶)的話，你有可能被告上法庭，而且你有可能被處以罰款除非你能證明你有不帶安全帶的理由。

　　5、Taiju Matsuzawa教授想找出為什么日本北部的健康農民在相對年輕的年齡就顯得開始失去思考與推理的能力的原因以及怎樣才能延緩老化過程。

　　6、在東京國立大學的同事們的幫助下，他開始對一千來自不同職業的人群進行了大腦體積的測量。

　　7、計算機技術幫助研究人員獲得人腦前部和側部的準確體積，這是與人的智能和情緒有關的部分，而且也決定人的性格特點。

　　8、有的人(大腦)前部和側部的收縮——隨著細胞的死亡——在三十多歲時就能被觀察到了，但是也有些人直到六七歲依然不明顯。

　　9、研究結果表明在農村的人大腦收縮基本上比城市里的人要早。

　　10、在政府部門從事簡單重復工作的白領也像農場工人、公共汽車司機和商店職員一樣大腦細胞容易收縮。
