4 Read the passage and choose the answer which best completes each sentence (1) 1)~(4). We all know that any person has a dream while they are sleeping. We also know that it is difficult to remember dreams after we wake up. Most dreams are soon forgotten and they disappear like small bubbles in water. In addition, they often cannot be remembered at all after they are forgotten. Even if you can remember a dream soon after you wake up, perhaps you cannot remember it any more after getting out from your bed to make some coffee. Maybe you have had such an experience. Then, have you ever noticed that you were having a dream while you were sleeping? / Some people have had such an experience. It is called a lucid dream, and some scientists in the world do research on it. Actually, there are even research groups which focus on it. Why do they do research on lucid dreams? For one thing, there may be advantages for us. We will be able to avoid nightmares and make our dreams happier or more exciting if we can notice we are having dreams and we can control them like a pilot. Today, scientists do not know enough about lucid dreams and how to control them, so there are still many things to be done in the research. But it may be possible for everyone to have lucid dreams if science in the area improves more. Actually, that is one of goals that some scientists are trying to reach. According to a survey, over 75% of the respondents answered that they experienced a lucid dream at least once in their lives. Also, many reports about lucid dream experiences were given in history. We can find early reports on them in books from ancient cultures. For example, an ancient Greek doctor already tried to use lucid dreams as a kind of therapy over two thousand years ago. And controlling our dreams in our own ways was one of the important topics among early Buddhists in Asia.

高校生 定期試験 問題文 今日あった試験の単語抜き取り問題です。 6.bombs 7．Pavilion 8．canvas 9．livestock 10．Guernica と答えたのですが、採点してほしいです…… 特に10はtragedyと答えてる人が多くて不安です

1. 次の文を読んで、問題に答えなさい。 Okamoto Taro, a Japanese artist, visited the Spanish Pavilion of the 1937 Paris Exposition. When he saw the painting Guernica, he (1)couldn't take his eyes off it. It was painted in black and white. But he felt like it was painted (2). (3) that the painting drew him into its world instantly. This big piece of work, 3.5 m 4 7.8 m, was painted 4 Pablo Picasso, a Spanish artist. (5) Picasso ( 6 ) to France in his (7), he painted it in Paris. He was 56 years old then, but he worked hard and completed it (8) within a month or so. This painting fascinated those who saw it at the Exposition. It became one of Picasso's best- known works among his over 10,000 paintings. Picasso was originally asked to paint something for the Exposition by the Spanish Republican government. However, he had not decided what to paint until he read a shocking newspaper article. According to the article, Guernica, a small town in Spain, was bombed by the Nazis on April 26, 1937. (9) In those days, the Nazis supported General Francisco Franco. He had been ( 10 ) to overthrow the Spanish government. ☆ The bombing started around 4 o'clock in the afternoon. People and livestock at a busy market (11) there ran (12) about, trying to escape from the attack. Many buildings, including a train station, hotels, and restaurants, were demolished. The bombing lasted about three hours, and 50 tons of bombs were dropped. Three-fourths of the town was destroyed, and several hundred people were killed. Picasso was shocked because the bombing was a cruel attack against the public in his home country. In order to protest against it, he decided to make a painting of the bombing. He struggled to paint the tragedy of the bombing. He drew a number of sketches trying to show the sorrow of the people in Guernica. Even after he started painting on a big canvas, he kept changing his ideas. 2133
