根据下列材料，请回答下面的题目Look After Your VoiceOften speakers, at a meeting experience dry mouths and ask for a glass of water. You can solve the problem by activating the saliva in your mouth. First gently bite the edges of your tongue with your teeth. Or, press your entire tongue to the bottom of your mouth and hold it there until the saliva flows. Or you can imagine that you are Slicing a big juicy lemon and sucking the juice.Before you begin your talk, be kind to your voice, Avoid milk or creamy drinks which dry your throat. Keep your throat wet by drinking a little sweetened warm tea or diluted fruit juice.If you sense that you are losing your voice, stop talking completely. In the meantime, do not even talk in a low voice. Save your voice for your health. You may feel foolish using paper to write notes, but the best thing you can do is to rest your voice. If it is necessary , perhaps you can get some advice from a professional singer.What about drinking alcohol to wet your throat? I advice you not to touch alcohol before speaking. The problem with alcohol is that one drink gives you a little confidence. The second drink gives you even more confidence. Finally you will feel all-powerful and you will feel you can do everything, but in fact your brain and your mouth do not work together properly. Save the alcohol until after you finish speaking.Perhaps you want to accept the advice, but you may wonder if you can ever change the habits of a lifetime. Of course you can. Goethe, who lived before indoor skating rinks or swimming pools, said, "We learn to skate in the summer and swim in the winter". Take this message to heart and give yourself time to develop your new habits. If you are willing to change, you will soon be able to say that you will never forget these techniques because they became a part of your body.To solve the problem of dry mouths, one is advised to take cool milk.
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：
回答下面的题目：Easy LearningStudents should be jealous．Not only do babies get to doze their days away, but they’ve also mastered the fine art of learning in their sleep.By the time babies are a year old they can recognise a lot of sounds and even simple words．Marie Cheour at the University of Turku in Finland suspected that they might progress this fast because they learn language while they sleep as well as when they are awake.To test the theory, Cheour and her colleagues studied 45 newborn babies in the first few days of their lives．They exposed all the infants to an hour of Finnish vowel sounds—one that sounds like “oo”, another like “ee” and a third boundary vowel peculiar to Finnish and similar languages that sounds like something in between．EEG recordings of the infants brains before and after the session showed that the newborns could not distinguish the sounds.Fifteen of the babies then went back with their mothers, while the rest were split into two sleep-study groups．One group was exposed throughout their night-time sleeping hours to the same three vowels, while the others listened to other, easier-to-distinguish vowel sounds.When tested in the morning, and again in the evening, the babies who’d heard the tricky boundary vowel all night showed brainwave activity indicating that they could now recognise this new sound．They could identify the sound even when its pitch was changed, while none of the other babies could pick up the boundary vowel at all.Cheour doesn’t know how babies accomplish this night-time learning, but she suspects that the special ability might indicate that unlike adults, babies don’t “turn off” their cerebral cortex while they sleep．The skill probably fades in the course of the first year of life, she adds—so forget the idea that you can pick up tricky French vowels as an adult just by slipping a language tape under your pillow．But while it may not help grown-ups, Cheour is hoping to use the sleeping hours to give remedial help to babies who are genetically at risk of language disorders.Babies can learn language even in their sleep.
