2 次は, 高校1年生の Yusuke が書いた英文です。 これを読んで、 問1~間6に答えなさい。*印 のついている語句には、本文のあとに 〔注〕があります。(34点) My father loves *dinosaurs and *fossils. He (he/them/in/collects/is/that/interested /so) dinosaur toys, small fossils and books about dinosaurs. I heard he tried to find fossils along the river with my grandparents when he was young. When I was younger, my family took me to the science museum every year. My father loved looking at the dinosaur fossils there, and he always explained them to me. So, I got interested in dinosaurs and fossils, too. My father has a restaurant near our house, and he displays some dinosaur teeth fossils in the restaurant. One day, he introduced one of his customers to me. The man, Mr. Shirai, also loved dinosaurs and fossils, and often visited museums all around the world, such as in America, Canada and China. He realized that my father was interested in the same things because of the fossils in the restaurant. They became good friends. One day in September, Mr. Shirai came to my father's restaurant and showed me a fossil. It was a beautiful fish fossil in a brown stone plate. I was surprised to see it, Mr. Shirai A me a lot about the fossil. He traveled to Germany to look for fossils, and he found many fossils there such as fish, animal bones and leaves. The area is very famous for "archaeopteryx fossils. I once saw a picture of the archaeopteryx fossil in a book, so I wanted to go to see the fossil in -4-

3 次の英文を読み, 空所に入れるのに最も適切なものを, それぞれ下の①~④のうちから一つずつ選びなさい。 Cigarette smoking has negative effects not only on the body of the person who smokes but also on the body of someone who regularly breathes in second-hand smoke. Some of the most obvious effects are high blood pressure, sleep disorders, heart failure, and lung cancer. Despite such harmful consequences, ( 10 ). It has been reported that smoking creates feelings of pleasure, reduces tension, and promotes close relationships. Many smokers admit that smoking is a bad habit. ( 11 ), they tend to think that the number of cigarettes that they smoke is below the danger level and thus are not worried about the risk. Some even feel that they do not breathe in the smoke and that a cure for cancer will be found before they become ill with the disease. We have to admit that smoking is a habit which is difficult to break ( 12 ) the nicotine found in tobacco goes into the blood and stimulates the brain, making smokers feel pleasant for several minutes. What is more, the smoker usually feels anxious and wants to have another cigarette. ( 13 ) the policies that now ban smoking in most public areas, the stress that people often experience at work and at home can force them to smoke. ( 10 ) ①some people decide to stop smoking millions of people continue to smoke ( 11 ) the price of cigarettes has risen ①smoking is more harmful than drinking Therefore 2 While ③ Of course 4 However (12) 1 because 2 as a result 3 but SO (13) ①Despite 2 Although (3) But 4 Yet

Many people believe that they would be. But research conducted over many years suggests that ( 8 ). People in the United States, for example, are, on average, richer than New Zealanders, but they are not happier. poorer people tend to worry about their financial problems 2 pleasure in life usually comes from great wealth (3) the best way to be happy is learning how to save money greater wealth doesn't generally imply greater happiness (9) Many European rivers were once heavily polluted by manufacturing industries. As a result, wild animals dependent on clean water disappeared. However, as stricter environmental standards took effect, rivers such as the Thames of London have become much cleaner. Consequently, ( 9 ). water quality has continued to decline wild animals avoid drinking from the Thames (3) wild animals are making a comeback in many rivers (4) wild animals no longer depend on clean water
