lo One fast-food company is well known in Japan for its extensive worker manual and the sales talk it covers. From the book, workers learn how to greet a customer, how to bow, how to take an order, pack a bag and give correct change. 5 Customers find the same nice service in all the franchised outlets, which contributes to both customer satisfaction and *corporate profits. One day, a mother came into one of these restaurants, and while she was ordering at the counter, her baby grabbed an 10 employee's hat and began to play with it. He was surprised and embarrassed. He could not concentrate on what the customer (2) was saying and had to ask her to repeat her order twice. He knew he was losing his dignity as a company representative by having an infant tearing up part of his uniform, and he wanted to 15 take it back, but at the same time he didn't know what to say or do. He stood there ( 3 ) until the mother *retrieved the hat and gave it back to him. He put it on again, resumed his normal calm attitude, and took her order efficiently as if nothing had happened. But everyone in the restaurant could see that a 20 one-year-old child had the power to bring the operation to a halt and must have wondered about it. What was the problem here? Simply put, the manual, detailed as it may be, fails to cover what to do in a situation where a young child steals part of your uniform. And without the manual to guide his behavior, the employee was lost. This is a trivial example of a very serious problem in Japan: the inability to 48

文法的に間違っているところがあれば教えて欲しいです。

agree with idea A, “Never do tomorrow what you can do today. Procrastination is the thief of time." I have three reasons to follow my opinion. First of all, people will forget what to do by putting it off and it will cause trouble to other. If you repeat it over and over again, you will lose trust. Second of all, procrastination is more likely to make a mistake. In general, procrastination often leads to failure because of uncertainties. You are always chased by time and you cannot afford it. Also, if you do it earlier, it will be taken more time, so the quality will be improved. Third of all, if you finish things early, you will have free time. By doing so, you can devote your free time to your hobbies. For example, going shopping, listening music, reading comic books, etc. According to these reasons that I think it is best not to put anything off.

問題は【1】~【4】まである。答えは各問題の指示に従って別紙の解答用紙に書きなさい。 【1】次の英文を読んで設問に答えなさい。 Headaches are a big problem. Each year, millions of people suffer from severe headaches that affect their enjoyment of life, (1) not to mention their productivity at work. estimate, headaches cost individuals and businesses more than (2) $50 billion each year! (3) This is one of the reasons research into headaches has become a worldwide effort. Although he did not know much about how headaches work, Hippocrates was the first doctor to find a way to treat them. By 400 BC, Hippocrates had discovered that the *bark from willow trees was useful in treating pain. He made a white powder from the tree's bark and gave it to his patients. Hippocrates did not know it, but he was actually prescribing a natural chemical in willow bark called salicin. Whena person eats salicin, the chemical is changed inside his or her body into (4) salicylic acid. It turns out that salicylic acid is good for stopping pain, including headache pain, but it is bad for a person's stomach. In the 1800s, a chemist in Germany slightly changed easier for people to take. commonly known as aspirin. Aspirin was used throughout most of the 1900s to treat headaches, but doctors had little idea about what really caused headaches. When doctors can *diagnose the cause of a disease, they can find better ways to treat it. Therefore, as medical technology developed, doctors began to use it to learn more about the human brain and about headaches. In fact, according to one m to make it This new form of the chemical was called acetylsalicylic acid, now acid's Now doctors classify headaches ( A ) two general types: primary and secondary. A primary headache is a condition ( B) as only the headache itself. one caused by another physiological condition, such as an *infection or a *tumor. For primary headaches, doctors have determined three possible causes. headache is caused by stress. characteristically felt on both sides of the head as a dull, steady pain. Another kind of primary headache is the *migraine headache. Exactly what causes these headaches is not well understood, but many experts believe it could be abnormal brain activity causing changes in the brain's chemistry and blood flow. For many people, migraines are caused by certain (5) stimuli, such as poor sleep or particular foods or smells. A sufferer usually feels intense pain on one side of the head and becomes sensitive to light and noise. If the migraine is severe, the sufferer may *vomit repeatedly. The third kind of primary headache is known as the cluster headache. Cluster headaches typically occur around the same time each day for weeks or months at a time. The person ( C)from this kind of headache usually feels pain on one side of her or his head, and the pain is centered around one of the eyes. Doctors do not know much (6) at present about cluster headaches, but they seem to be more common among men and could be related to alcohol or other things that affect a person's blood flow. Using computers and more advanced medical equipment, doctors continue to learn more about what happens in the brain before and during headaches. Especially in the case of migraines, some doctors believe they have found the part of the brain that sets off the reaction for severe attacks. With these insights into brain processes, doctors hope new ways will be discovered to stop headaches before they begin. On the other hand, a secondary headache is One kind of primary Doctors usually call these tension headaches, and they are 注: bark 樹皮 diagnose ~を診断する、~を突き止める 感染症·伝染病 migraine (headache) 偏頭痛 infection tumor 腫場 vomit 食べたものを吐く (出典:READING FOR THE REAL WORLD 3rd edition, Compass Publishing より)
