　　5、Taiju Matsuzawa 教授想找出為什么日本北部的健康農(nóng)民在相對(duì)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(xué)的同事們的幫助下，他開始對(duì)一千來自不同職業(yè)的人群進(jìn)行了大腦體積的測量。

　　7、計(jì)算機(jī)技術(shù)幫助研究人員獲得人腦前部和側(cè)部的準(zhǔn)確體積，這是與人的智能和情緒有關(guān)的部分，而且也決定人的性格特點(diǎn)。

　　8、有的人(大腦)前部和側(cè)部的收縮——隨著細(xì)胞的死亡——在三十多歲時(shí)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(jié)果表明在農(nóng)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(fù)工作的白領(lǐng)也像農(nóng)場工人、公共汽車司機(jī)和商店職員一樣大腦細(xì)胞容易收縮。

　　11. We know that you have a high opinion of the kind of learning taught in your colleges, and that the costs of living of our young men, while with you, would be very expensive to you.

　　12. But you must know that different nations have different ways of looking at things, and you will therefore not be offended if our ideas of this kind of education happen not to be the same as yours.

　　13. We are, however, not the less obliged by your kind offer, though we refuse to accept it; and, to show our grateful sense of it, if the gentlemen of Virginia will send us a dozen of their sons, we will take care of their education, teach them in all we know, and make men of them.

　　14. In what now seems like the prehistoric times of computer history, the earth‘s postwar era, there was quite a wide-spread concern that computers would take over the world from man one day.

　　15. Already today, less than forty years later, as computers are relieving us of more and more of the routine tasks in business and in our personal lives. We are faced with a less dramatic but also less foreseen problem.

　　16. Obviously, there would be no point in investing in a computer if you had to check all its answers, but people should also rely on their own internal computers and check the machine when they have the feeling that something has gone wrong.

　　17. Certainly Newton considered some theoretical aspects of it in his writings, but he was reluctant to go to sea to further his work.

　　18. For most people the sea was remote, and with the exception of early intercontinental travellers or others who earned a living from the sea, there was little reason to ask many questions about it, let alone to ask what lay beneath the surface.

　　19. The first time that the question “ What is at the bottom of the oceans?” had to be answered with any commercial consequence was when the laying of a telegraph cable from Europe to America was proposed.

　　20. At the early attempts， the cable failed and when it was taken out for repairs it was found to be covered in living growths, a fact which defied contemporary scientific opinion that there was no life in the deeper parts of the sea.
