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.

　　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.

　　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.

    21. For every course that he follows a student is given a grade, which is recorded, and the record is available for the student to show to prospective employers.

　　30. The teacher was not wrong to draw attention to the errors, but if his priorities had centred on the child‘s ideas, an expression of his disappointment with the presentation would have given the pupil more motivation to seek improvement.

31. Given the nature of government and private employers, it seems most likely that discrimination by private employers would be greater.

　　32. The release of the carbon in these compounds for recycling depends almost entirely on the action of both aerobic and anaerobic bacteria and certain types of fungi.

　　45. It was possible to demonstrate by other methods refined structural differences among neuron types, however, proof was lacking that the quality of the impulse or its conduction was influenced by these differences, which seemed instead to influence the developmental patterning of the neural circuits.

　　46. According to this theory, it is not the quality of the sensory nerve impulses that determines the diverse conscious sensations they produce, but rather the different areas of the brain into which they discharge, and there is some evidence for this view.

　　47. The result of attrition is that, where the areas of the whole leaves follow a normal distribution, a bimodal distribution is produced, one peak composed mainly of fragmented pieces, the other of the larger remains.
