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 while running. Cold weather during winter months, with low temperatures and freezing cold winds, may keep many 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.
Lower temperatures reduce stress on the body. When you run in cold weather, your heart rate is lower. And the body needs less water on a cold day than in warm weather because dehydration levels are lower in winter than in warmer conditions.
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 droplets of sweet. The body also loses it by transporting the blood to the surface of the skin and it puts more stress on the heart, particularly 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 heart rates.
When running in cold conditions, the body does not have to work hard to pump 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 mittens on your hands instead of gloves. Wear more than one layer of 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.

Ancient Greek historian Thucydides suffered from the disease. Luckily, he got well. He said that birds and animals were also affected and that doctors were among the most affected by it. Modern historians think it caused the fall of ancient Greece(古希腊).
Black Death Black Death came from central Asia first and was carried by fleas(跳孟) living on rats(老鼠). The skin of a person with this disease would turn black in places. It killed about 25,000,000 people in the 14th century. Because of the disease, there were not enough farmers in Europe.
The Epidemic(流感) of 1918 The epidemic broke out in Spain in May 1918. Within months, it killed more people than any other illness in recorded history. It caused about 50 million deaths worldwide. The flu greatly changed the social situation at that time.

Running is becoming popular these days. Many of us run for our health. Doctors say many of the health problems come from these bad habits: eating too much, drinking too much, smoking, and not taking enough exercise. Doctors tell us, “eat and drink less, don’t smoke, and exercise more.”
Running is a good form of exercise because it helps build a strong heart. It also helps most people lose weight. One 68-year-old woman runs three times a week. She runs to lose weight.
Running is good for health in other ways, too. Many runners say running keeps colds and other small health problems away. “Running is my doctor.” says one man.
Running can also help people to relax. So today men and women of all ages enjoy running.

About ten men in every hundred have the trouble of colour blindness in some way. Women are luckier, only about five in every hundred are affected in this matter. Perhaps, after all, it is safer to be driven by a woman.
　　There are different shapes of colour blindness. For example, a man may be able to see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person cannot tell the difference between blue and green. Only a few unlucky men may see everything in shades of green a strange world indeed.
Color blindness in human beings is a strange thing to say clearly. In only one eye there are millions of very small things called “cones”(圆锥细胞). These help us to see in a bright light and to tell difference between colors. There are also millions of “rods”(棒), but these are used for seeing when it is nearly dark. They show us shapes but no colors. People suffer from colour blindness when there is something wrong with the cones.
Some insects have favourite colors. Mosquitoes(蚊子) like blue but do not like yellow. A red light will not attract insects, but a blue light will. Human beings also have favourite colors. Yet we are lucky. With the help of the cones in our eyes we can see many beautiful colors by day, and with the help of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.
19．Which of the following is true
A．Red, orange and yellow are all shades of green.
B．Nobody can tell the difference between green and blue.
C．Fewer woman have the trouble of color blindness than men.
D．It’s easy for human beings to explain the color blindness clearly.
20．Why do people have the trouble of color blindness
A．Because something is wrong with people’s cones.
B．Because there are no differences between colors.
C．Because it’s too dark for people to see the colors.
D．Because “rods” show people shapes but no colors.
21．What’s the best title for this passage
A．Color blindness B．Insect’s favourite colors
C．Different shapes of color blindness D．The cause of color blindness

These years people show all kinds of things on the Internet—good food, nice clothes, wonderful vacations and so on. Now showing the number of steps is becoming popular, too. Why
People are finding it important to be in good health. To keep healthy, many people go to work on foot.

You might think that drinking fruit juice is healthy. But that’s not quite true. A study (研究) shows that drinking too much juice — even 100% fruit juice — will do great harm to your health and can even make you die early.
This is because these drinks have a lot of sugar. Scientists said drinking too much fruit juice is just like drinking too much soda (汽水) — they both have a lot of sugar. Eating too much sweet food can cause many health problems, such as getting fat and heart disease. Fruit juice has vitamins (维生素) , but there are very few vitamins in it.
In the study, both soda and 100% fruit juice are “ sweet drinks” . Scientists found that if people get 10% or more of their energy from sweet drinks every day, they may die from heart disease or other diseases. Jean Welsh, one of the scientists in the study, told CNN, “ People should drink less sweet drinks, whether soda or fruit juice. ”
Does this mean that eating fruit is also unhealthy Fruit is still fine. When you eat 100g of fruit, you’re getting less sugar than if you drink 100g of juice, because the fruit has lots of fiber (纤维) . This fiber is also good for our health. It’s better to eat the whole fruit instead of fruit juice.

Mrs. Lee was at my mother’s hospital for a long time. She hurt her back in an accident. Every day, she had to take a special medicine to reduce the pain in her back. It tasted really terrible.
One day, the nurse came in to give Mrs. Lee her water and medicine. She walked into the cleaner, who was cleaning the floor. The nurse spilled the water all over the poor cleaner.
The nurse was helping the cleaner when they heard someone laughing. Mrs. Lee had her hands in front of her mouth, trying her best not to laugh. This made the nurse and the cleaner laugh, too. My mother came running into the room to see what had happened. Guess what! Mom slipped on the wet floor. She wasn’t hurt. It made the other three laugh even harder.
When everyone stopped laughing, Mrs. Lee said,“You know, when I was laughing, I didn’t notice the pain. Even now I feel it less than I normally do.”
This gave my mother an idea. She brought in a lot of movies. Now, Mrs. Lee watches a movie every day. The actors always make her laugh. The most amazing thing is that she now uses fewer pills to stop her pain.
