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)

SIMなし合 22:01 Cop 【1】次の英文を読んで, 設問 1~12に答えなさい。 なお, *印の語(句)には文末に注 がついています。 Modern examinations of working conditions in British and U.S. industry in the nineteenth and early twentieth centuries concentrate mainly on the experiences, Complaints, and overall difficulties of working-class laborers. The first complaint that a majority of industrial workers had was that their workdays* were too long. The average (ア) of hours in a shift varied from industry to industry, from place to place, and from era to era. Workers in British and American textile mills* in the early to middle 1800s generally worked twelve to fifteen hours, six days a week, ( イ) only Sundays off. Their average workweek* was seventy-eight hours. In contrast were the hours of workers who labored in American steel mills in the late 1800s. The length of their shifts was determined by the fact that the blast furnaces* they tended almost always operated twenty-four hours a day. Thus, (oit became customary* for steel mills to have two twelve-hour shifts. However, many of the steel workers labored seven days a week. (a)That gave them a workweek of sighty-four hours. Moreover, sometimes they had to work extra hours on top of this demanding schedule. (オ )the minor differences in the length of workweeks from one industry to another, the average worker put in twelve-to fourteen-hour days at least six days a week, This harsh schedule remained more ( カ) less standard well into the twentieth century. It was not until 1920 that a fifty-hour workweek was introduced in the United States. Anda forty-hour week did not become the rule in most industries until 1938. Low wages was another common complaint of industrial workers. In 1851, the average wage earned by American industrial workers in general was seven to ten dollars per week. That same year New York's Daily Tribune* reported that a worker's family of five required just over ten dollars a week just for basics such as rent, food, and fuel. Most ordinary workers could not afford many simple comforts that middle-class workers enjoyed. (o This miserable situation lasted in America for decades and improved only slowly. As late as 1912, a study found that only 15
