Passage Five
Scientists claim that air pollution causes a decline in the world’s average air temperature. In order to prove that theory, ecologists have turned to historical data in relation to especially huge volcanic eruptions. They suspect that volcanoes effect weather changes that are similar to air pollution.
One source of information is the effect of the eruption of Tambora, a volcano in Sumbawa, the Dutch East Indies (the former name of the Republic of Indonesia), in April 1815. The largest recorded volcanic emption, Tambora threw 150 million tom of fine ash into the stratosphere. The ash from a volcano spreads worldwide in a few days and remains in the air for years. Its effect is to turn incoming solar radiation into space and thus cool the earth. For example, records of weather in England show that between April and November 1815, the average temperature had fallen 4.5°F. During the next twenty-four months, England suffered one of the co
A. England's proximity to the North Sea
B. Volcanic ash in the atmosphere
C. Floorings in the area

For example, records of weather in England show that between April and November 1815, the average temperature had fallen 4.5°F. During the next twenty-four months, England suffered one of the coldest periods of its history. Farmers’ records from April 1815 to December 1818 indicate frost throughout the spring and summer and sharp decreases in crop and livestock markets. Since there was a time lag of several years between cause and effect, by the time the world agricultural commodity community had deteriorated, no one realized the cause. Ecologists today warn that we face a twofold menace. The ever-present possibility of volcanic eruptions, such as that of Mt. St. Helens in Washington, added to man’s pollution of the atmosphere with oil, gas, coal, and other polluting substances, may bring ms increasingly colder weather. According to the passage, the effects of Tempura’s eruption were （）
A. of several days’ duration worldwide
B. felt mainly in the Dutch East Indies
C. evident in the decreased world temperature
D. immediately evident to the world’s scientists

[填空题]Around the world more and more people are taking part in dangerous sports and activities. Of course, there have always been people who have looked for 1 —those who have climbed the highest mountains, 2 unknown parts of the world or sailed in small boats across the greatest oceans. Now, however, there are people who seek an immediate excitement from a risky activity which may only last a few minutes or even seconds.
I would consider bungee jumping to be a good example of such an activity. You jump from a high place, 200 meters above the ground with an 3 rope tied to your ankles. You fall at up to 150 kilometers an hour until the rope stops you from hitting the ground. Other activities which most people would say are as risky as bungee jumping 4 jumping from tall buildings and 5 into the sea from the top of high 6 .
Why do people take part in such activities as these Some psychologists suggest that it is because life in modem societies has become safe and boring. Not very long ago, people’s lives were constantly under threat. They had to go out and 7 food; diseases could not easily be cured, and life was a 8 battle for survival.
Nowadays, according to many people, life offers little excitement. They live in 9 safe environment; they buy food in shops; and there are doctors to 10 them ff they become ill. The answer for some of these people is to seek danger in activities such as bungee jumping.
