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)

Masters of the Desert “Bedouin” is a name given to some of the people who live in North Africa and the Middle East. Unlike most people, many Bedouins do not ( 24 Instead, they are nomads, which means that they are always moving about. They walk around the hot deserts of countries like Egypt and Israel, leading their camels and sheep to gras and water. Life in the desert is not easy, but over thousands of years, Bedouins have developed unique skills to help them survive. Some people estimate that there are around 20 million Bedouins in the world today. However, ( 25 ). Because many of them are traveling, it is impossible to count them all. In recent years, however, many Bedouins have given up their traditional way of life. This is because the amount of land controlled by governments has increased, which has made it harder for the Bedouins to travel freely. Some of them now live in urban areas and have regular jobs, such as driving taxis and working in restaurants. Some Bedouins have found work with the Israeli army as trackers. A tracker is a person who follows people by using signs left on the ground, such as the marks left by feet or tires. Trackers must know their environment well and be quick to notice anything unusual. ( 26 ), with their desert survival skills, Bedouins are excellent trackers. About 1,600 of them are now serving in the Israeli army, and their ability to notice dangers along Israel's borders is helping to protect the countily. 1 sleep lying down 2 live in one place 3 eat meat or fish 4 use paper money 1 their exact numbers are unknown 2 there were many more in the past 3 the groups have no government 4 they all meet once every year 1 Naturally 2 Occasionally 3 Secondly 4 Equally
