We humans really like the Sun. We love the 1 the Sun provides. Do you know how 2 the Sun is to us here on Earth? What would happen if the Sun 3 disappeared or went out?

Everything in the solar system goes around the Sun. The Sun draws all the planets in the solar system toward it. Since Earth and all the other planets are moving very fast through space, the Sun’s presence (存在) keeps them 4 around itself. If the Sun were to suddenly disappear, Earth and the other planets would keep their 5 motion(運(yùn)動), flying off into outer space in a straight line.

While some humans might be able to survive on a Sun-less Earth for several days, months, or even light from the Sun 6 eight and a half minutes to reach Earth, so we wouldn’t notice immediately if the Sun suddenly went out. However, nine minutes later, we would find 7 in complete darkness.

Without the Sun’s warmth, Earth would quickly become a much 8 place. 9estimate (估計) that the average global surface temperature would drop below -17 within a week or so. Within a year, the average global surface temperature could drop below -70! Years, life without the Sun would eventually(最終)be10 to maintain (維持).

【題目】 Chris is not a traditional explorer(探險者) he usually works in an office for a large organization. Yet his job can sometimes be just as exciting and dangerous as being an explorer.

Chris works for MSF, an organization also known as Doctors Without Borders(無國界醫(yī)生). MSF sends trained doctors all over the world to help people after a war or a disaster. Chris is a doctor from France who has travelled to many places to organize programs that help people.

At the moment, there are over 27,000 trained medical staff(職員) taking part in MSF projects and tasks. The organization received the Nobel Peace Prize in 1999. All kinds of doctors can volunteer for MSF. They need to be prepared to go almost anywhere in the world and, of course, they should expect difficult conditions. Doctors with experience in tropical(熱帶的) diseases are especially useful because most of MSFS work is in Africa. When MSF accepts a doctor for a task, he has to go for at least six months. When doctors have completed a few tasks, they might be sent on an emergency task following a disaster, such as an earthquake.

But why would a doctor leave a comfortable life and a good salary to join MSF? According to Chris, the experience you get is a great help in your career(職業(yè)生涯). Besides, just like the explorers of the past, you need to keep an open mind and learn to mix well with the people you meet. Most importantly, at the end of each task, you have made a real difference to people’s lives.

1Does Chris work for a large organization?

2How many medical staff are taking part in MSF projects and tasks?

【題目】 Cold weather during winter months may stop many people from _______home and running in the open air. But a new study shows _______ the drop in temperature is a good reason to run. In fact, researchers say, running in cold weather _______ improve one's performance (性能). Many people say running in _______ winter is difficult. Two reasons are the low temperatures and strong winds. Yet many runners might find _______ easier than running in hot weather. That could be because lower temperatures reduce stress on the body.

When you run in cold weather, your heart rate is _______ than in warmer conditions. Besides, the body needs less water _______ a cold day than in warm weather. This information comes from John Brewer, a sports scientist at St. Mary's University in London. Brewer says every movement runners make produces heat. He explains that one way in which we lose heat is by sweating, and that the body loses heat by transporting the blood to the surface of the skin. But sweating puts much strain (張力) on the heart, particularly in hot conditions because it is _______ harder to lose heat when the external environment is warm as well.

In addition, running in higher temperatures results in faster heart rates. Scientists find that heart rates are about 6 percent higher in the hotter conditions. _______, running in cooler temperatures has some advantages. One is that the body does not have to work so hard to pump (輸送) blood to the skins surface in cooler temperatures, which means running requires less energy. Several websites note that the most important thing for people ________ run in cold conditions is to wear the right clothing. And especially, keeping as dry as possible is very important when exercising in low temperatures.
