    The word 'day' has two meanings. When we talk about the number of days in a year. We are using 'day' to mean 24 hours. But when we talk about day and night. We are using 'day' to mean the time between sunrise and sunset. Since the earth looks like a ball. The sun can shine on only half of it at a time. Always one half of the earth is having day and the other half night. A place. is moved from day into night and from night into day over and over by the spinning(旋转)of the earth. At the equator(赤道)day and night are sometimes the same length, they are each twelve hours long. The sun rises at 6 o'clock in the morning and sets at 6 o'clock in the evening. For six months the North Pole is tilted(倾斜)toward the Sun. In those months the Northern Hemisphere(半球)gets more hours of sunlight than the Southern Hemisphere. Days are longer than nights. South of the equator nights are longer than days. For the other six months the North Pole is tilted away from the SUN. Then the Southern Hemisphere gets more sunlight. Days are longer than nights. North of the equator nights ate longer than days. Winter is the season of long nights. Summer is the season of long days.

(1)、When the Western Hemisphere is having day. The Eastern Hemisphere is having_____.
A、both day and night B、day C、neither day nor night D、night
(2)、At the equator day is________ as long as night.
A、sometimes B、never C、usually D、always
(3)、When the North Pole is tilted toward the sun, the Northern Hemisphere gets_________ sunlight.
A、less B、more C、all D、no
(4)、When it is winter in China, ________.
A、the USA is tilted toward the sun B、the South Pole is tilted away from the sun C、the North Pole is tilted toward the sun D、the North Pole is tilted away from the sun

Many people take running as a way to keep fit. They like to run in hot weather and enjoy the feeling of being wet through with sweat (汗) while running. Cold weather during winter months, with low temperatures and freezing cold winds, may keep people from running in the open air.

However, a new study shows that the drop in temperature is a good reason to run. In fact, running in cold weather helps improve one's performance. Many runners might find it easier to run in winter than in hot weather. The body needs less water on a cold day than in warm weather. In addition, lower temperatures reduce stress on the body. When you run in cold weather, your heart rate is lower.

John Brewer is a professor of applied sports science at St. Mary's University in London. For this study, he and other researchers put a group of people into a room where summer and winter weather conditions are recreated. The test subjects were asked to run 10,000 meters under both conditions and their biological measurements were recorded and studied.From the study, every movement runners make produces heat. The heat can be really damaging unless the body can lose it. One way in which people lose heat is by sweating. The body loses heat through sweat. The body also loses it by transporting the blood to the surface of the skin and it puts more stress on the heart, especially in hot conditions because it's much harder to lose heat when the outside environment is warm. As the result shows, running in hot temperatures results in 6 percent higher heat rates.

When running in cold conditions, the body does not have to work hard to move blood to the skin surface. Therefore, it requires less energy. The most important thing for people who run in cold conditions is to wear the right clothing. Keep as dry as possible when exercising in low temperatures. Wear warm and light clothing to keep sweat away from your skin. So don't let winter weather keep you indoors. Simply get ready for the low temperatures and start running.

阅读下面短文,在空格处填入一个适当的词或使用括号中词语的正确形式填空。

There are several different kinds of sea turtles in the world. The sea turtles are endangered. Several are in danger of being gone {#blank#}1{#/blank#} ( complete).

Sea turtles lay large groups of eggs under the sand on beaches. The eggs face many challenges, both natural and man- made. In Costa Rica, one big challenge is poachers(偷猎者)— they take the eggs in order to sell {#blank#}2{#/blank#} ( they).

Kim Williams Guillen is {#blank#}3{#/blank#} scientist. She works for the University of Michigan and Paso Pacifico. She works {#blank#}4{#/blank#} ( protect) animals in Costa Rica. AfterKim{#blank#}5{#/blank#}( watch) some TV shows, she suddenly had an idea. What if poachers could be followed by using a fake(假的) t urtle egg {#blank#}6{#/blank#}a GPS tracker(跟踪器) inside?

Dr. Williams Guillen showed that idea and it won a $10,000 prize. She then worked with other scientists to create the fake egg. It was made of a special material, just like a ping- pong ball.{#blank#}7{#/blank#} it was cheap and easy to make fake eggs, they made a lot of them.

The scientists put some fake eggs into 101 {#blank#}8{#/blank#} ( difference) t urtle nests in Costa Rica. According to the results, most eggs {#blank#}9{#/blank#} ( sell) to local people. That wasn't a big surprise, since in Costa Rica, turtle eggs are considered a special kind of food.

The scientists are excited about the results of the fake eggs. The test shows that such simple ways can work well. The scientists believe that similar ideas could be helpful in other{#blank#}10{#/blank#}( place) as well.
