One way to get salt is to53seawater in shallow basin and leave until it evaporates( 蒸发 ). Along with salt, other minerals are left 54 evaporation.Much gold and silver drift dissolved in the waters of the sea, too.

Seaweed becomes 58 of many kinds-even candy, and ice cream - as well as medicine. Believe it or not, fresh water is another 59 from the sea. We cannot drink ocean water. Some of its contents may. 60 illness. But ocean water becomes fresh water when the salts are 61 . In the future, we will find ourselves 62 more and more on fresh water from the sea. The sea63us food, fertilizer, minerals, water, and other gifts. What do we give the sea? Garbage. We pollute the ocean 64 we use it as a garbage dump. Huge as it is, the ocean cannot hold all the water that we pour into it. 65 garbage into the ocean is killing off sea life.

回答下面的题目:Exercise Being Good or BadCan exercise be a bad thing? Sudden death during or soon after strenuous exertion on the squash court or on the army training grounds, is not unheard of. 51 trained marathon runners are not immune to fatal heart attacks. But no one knows just 52 common these sudden deaths linked to exercise are. The registration andinvestigation of such 53 is very patchy; only a national survey could determine the true 54 of sudden deaths in sports. But the climate of medical opinion is shifting in 55 of exercise, for the person recovering from a heart attack as 56 as the average lazy individual. Training can help the victim of a heart attack bylowering the 57 of oxygen the heart needs at any given level of work 58 the patient can do more before reaching the point where chest pains indicate a heart starved of oxygen. The question is, should middle-aged people, 59 .particular, be screened for signs of heart disease before 60 vigorous exercise?Most cases of sudden death in sport are caused by lethal arrhythmias in the beating of the heart, often in people 61 undiagnosed coronary heart disease. In North America 62 over 35 is advised to have a physical check-up and even an exercise electrocardiogram. The British, on the whole, think all this testing isunnecessary. Not many people die from exercise, 63 , and ECGs ( 心电图 ) are notoriously inaccurate. However, two medical cardiologists at the Victoria Infirmary in Glasgow, advocate screening by exercise ECG for people over 40, or younger people 64 at risk of developing coronary heart disease. Individuals showing a particular abnormality in their ECGs 65 , they say, a 10 to 20 times greater risk of subsequently developing signs of coronary heart disease, or of sudden death.第51题应选：

根据材料，回答问问题。The Science of the Future      Until recently, the "science of the future" was supposed to be electronics and artificialintelligence. Today it seems more and more likely that the next great breakthroughs intechnology will be brought through a combination of those two sciences with organic chemistryand genetic engineering. This combination is the science of biotechnology.       Organic chemistry enables us to produce marvelous synthetic (合成的) materials. However,it is still difficult to manufacture anything that has the capacity of wool to conserve heat and alsoto absorb moisture. Nothing that we have been able to produce so far comes anywhere near thecombination of strength, lightness and flexibility that we fred in the bodies of ordinary insects.Nevertheless, scientists in the laboratory have already succeeded in "growing" a material that has many of the characteristics of human skin. The next step may well be "biotech heartsand eyes" which can replace diseased organs in human beings. These will not be rejected by thebody, as is the case with organs from humans.       The application of biotechnology to energy production seems even more promising. In1996 the famous science-fiction writer, Arthur C. Clarke, many of whose previous predictionshave come true. He said that we may soon be able to develop remarkably cheap and renewablesources of energy. Some of these power sources will be biological. Clarke and others havewarned us repeatedly that sooner or later we wi/1 have to give up our dependence on non-renewable power sources. Coal, oil and gas are indeed convenient. However, using them alsomeans creating dangerously high levels of pollution. It will be impossible to meet the growingdemand for energy without increasing that pollution to catastrophic (灾难性的) levels unlesswe develop power sources that are both cheaper and cleaner.      It is attempting to think that biotechnology or some other "science of the future" can solveour problems. Before we surrender to that temptation we should remember nuclear power.Only a few generations ago it seemed to promise/imit/ess, cheap and safe energy. Today thosepromises lie buried in a concrete grave in a place called Chernobyl, in the Ukraine.Biotechnology is unlikely, however, to break its promises in quite the same or such a dangerousway.According to the passage, the science of the future is likely to be__________
