(5)についてeat the foodsではダメですか?

erdeen me we w break ma 東京医科歯科大 One reason may be breakfast's nutritional value-partly because cereal is Tarified with vitamins. In one study on the breakfast babits of 1.600 young people Julete, vitamin C, iron and calcium, was better in those who had breakfast in the U, researchers found that the fire and micronutrient intale, including of regularly. There have been sämiäer finelings in Australia, Brazil, Canada and the Breakfast is also associated with improved brain function, including concentration and language. A review of 54 studies found that eating breakfast can improve memory, though the effects on other brain functions were inconclusive. However, one of the review's researchers, Mary Beth Spitznagel says there is "reasonable" evidence breakfast does improve concentration-there just needs to be more research. "Looking at studies that tested concentration, the number of studies showing a benefit was exactly the same as the number that found no benefit," she says. "And no studies found that eating breakfast was bad for concentration." What's most important, some argue, is what we eat for breakfast. High-protein breakfasts have been found particularly effective in reducing food fravings and consumption later in the day, according to research by the Australian Commonwealth Scientific and Industrial Research Organisation. While cereal remains a firm favourite among breakfast consumers in the UK and US, a recent Which? investigation into the sugar content of 'adult' breakfast cereals found that some cereals contain more than three quarters of the recommended daily amount of free sugars in each portion, and sugar was the second or third highest ingredient in seven out of 10 flaked cereals. 5)PV But some research suggests if we're going to eat sugary foods, it's best to do it early. One study found that changing levels of the appetite hormone leptin in the body throughout the day coincide with having our lowest threshold for sweet food in the morning, while scientists from Tel Aviv University have found that hunger is best regulated in the morning. They recruited 200 obese adults to take part in a 16-week-long diet, where half added dessert to their breakfast, and half didn't. Those who added dessert lost an average of 40 lbs (18 kg) more-however, the study was unable to show the long-term effects.

(2)の訳は 「そのことについて考えれば考えるほどストレスには私たちにとって何かが価値があるように思われた」 なのですが、訳を書く時に「そのこと」と書くのは違和感があります。aboutの後ろのitはit=stressですよね? だとしたら「ストレスについて...」と書いても... 続きを読む

次の英文を読んで, 設問に答えなさい。 25 min. 454 words 2 25分ぐ終了 ( Listening to a gardening program the other day, I was struck by something the /S-70₂ expert said about a particular type of potted plant. Do not water it once it has *come into bud, he advised. Cause it to feel stress, and it will produce more, and more beautiful, flowers. 52 Surely this advice is against everything that we are told by doctors. Stress is bad for us, they say. Stress is the cause of all sorts of diseases. Stress caused by overwork sometimes results in early death. Newspaper and magazine articles tell us how to reduce stress, or how to avoid it altogether. No one has a good word for stress. 10 3 And yet, I asked myself, if stress is good for plants, can there possibly be any value for us in it? The longer I thought about it, the more it seemed to me that there is. Without a certain degree of tension and stress, we are apt to become lazy and neglect our duties. All students know that they should study regularly throughout the year, and then be able to face examinations without fear. In fact, 15 most students leave this study till the last possible moment, and then hastily try to ( 3 ) lost time. Many of us, likewise, put off dealing with our problems until the deadline approaches. Every year I resolve that I will write all my Christmas cards and letters ahead of time, and avoid a last-minute rush; and every year I find that 20 once again I have left it too late for me to finish comfortably. Only when the tension increases [working seriously / the job / do / to get/I/done / start]. (4) In other fields too, when satisfaction enters in, creativity and curiosity go out of the window. What has been called "divine discontent" - a creative dissatisfaction (5) with the present situation, whatever it is produces progress. And that 25 dissatisfaction is one type of stress. 6Thus, it seemed to me, a certain degree of stress is necessary for human progress. Just how much is good, and how much is harmful, is the problem. Those of us who are employed by a company/whose policies demand long periods of stressful activity/are to be sympathized with, since too much stress is activity/are
