Many scientists believe our love of sugar may actually be an addiction. When we eat or drink sugary foods, the sugar enters our blood and affects parts of our brain that make us feel good.
1.In this way, it is in fact an addictive drug, one that doctors recommend we all cut down on.
“It seems like every time I study an illness and trace a path to the first cause, I find my way back to sugar,” says scientist Richard Johnson. One-third of adults worldwide have high blood pressure, and up to 347 million have diabetes. Why? “ 2.“ says Johnson.
Our bodies are designed to survive on very little sugar. Early humans often had very little food, so our bodies learned to be very efficient in storing sugar as fat. In this way, we had energy stored for when there was no food. But today, most people have more than enough. 3.
So what is the solution? It’s obvious that we need to eat less sugar. 4.From breakfast cereals to after-dinner desserts, our foods are increasingly filled with it. Some manufacturers even use sugar to replace taste in foods that are advertised as low in fat.
But there are those who are fighting back against sugar. 5.Other schools are growing their own food in gardens, or building facilities like walking tracks so students and others in the community can exercise. The battle has not yet been lost.
A. We take in more energy and fat.
B. Then the good feeling goes away, leaving us wanting more.
C. Our ancestors were used to poor food, clothing and shelter.
D. So the very thing that once saved us, may now be killing us.
E. Sugar, we believe, is one of the reasons, if not the major one.
F. The trouble is, in today's world, it's extremely difficult to avoid.
G. Many schools are replacing sugary desserts with healthier options like fruit.
Nobody needs reminding that exercise is good for our health, but we may need reminding that it needs to be done in the right way.
Light exercises are a great way to improve circulation and keep our muscles active, especially if the rest of the day will be spent sitting in front of a computer or in a lecture hall. However, certain sports like long distance running require training to build up our bodies so they can handle the challenge. If we go into such sport cold, it can shock our muscles, hearts, lungs, and other organs and cause severe pain or in some cases, even death.
Some people are born with medical conditions that go unnoticed until they stress the unstable part of their body. A weak heart may never be seen until we do something that causes extreme physical effort. Recently there have been cases of people dying while running long distances. Also, a university student died after taking a 1.000m running exam. Some universities and high schools have cut long distance races (i.e. 3.000m, 5,000m) from their campus sports games, partly because of the supposed danger and partly because they say fewer people are entering such events.
Maybe education about such events is lacking, especially during primary and high school. People participating in such competitions should realize that a reasonable amount of training is required beforehand and having a medical check is wise, especially for a marathon. People shouldn’t be forced to participate in events that push them past their limits, especially if they haven’t warmed-up completely. Cancelling events could lead to people becoming less healthy and overweight. Maybe these events shouldn’t be cancelled, but organizers and participants should be more careful about regular health checks.

D.Because they worry about the supposed danger in such races.
4.What does the author advise us to do before running a marathon?
A.Have a medical check and warm-up exercises.

Two British teachers have broken the world record for the longest journey in a tuk-tuk after pulling their failing vehicle for 43 miles. Richard Sears and Nick Gough traveled 37,500 kilometers around the world and passed through 37 countries. They did this to support grassroots education project in Africa, Asia and South America.
The pair, who set off from London, thought their expedition was over when the vehicle started to fail. When the tuk-tuk broke, they were only 70 kilometers from their destination. They decided to pull it the rest of the way. The tuk-tuk, which weighs 800 kilograms, was pulled in turns by Rich and Nick over three days. On arrival in Chepen, Peru, they discovered a mechanic who specialized in tuk-tuks and managed to fix it.
The pair were back on the road and aiming for their next goal. Along their journey they had to tackle deserts and jungles. They also survived close encounters with elephants in Uganda and Botswana and an accident in Malaysia. The greatest hardship on the tuk-tuk was the mountain ranges lying in their path, including the Alps, the Himalayas and the Andes.
Nick and Richard uncovered some inspirational projects across Africa, Asia and South America. They witnessed firsthand the educational challenges facing these areas today. They joined street children in the slums of Cairo, Khartoum, Kampala, Mumbai and Phnom Penh. They visited Congolese refugees (难民) in camps in Eastern Burundi. They witnessed how education could free sex-workers in Delhi and victims of human trafficking in Nepal.
The pair established The Tuk Tuk Educational Trust, a U.K. registered charity.
Talking bout their motivation, Richard said: “The world’s leaders have made a commitment to achieving universal primary education but, in spite of this pledge (誓言，承诺), over 57 million primary-aged children worldwide are still out of school; many more are in school, though still cannot access quality learning opportunities.”

Up till about 130 years ago, newspapers in the United States attracted only the most serious readers. They used no illustration (插图) and the articles were about politics or business.
Two men changed that - Joseph Pulitzer bought the New York World and William Randolph Hearst of the New York Journal. Pulitzer bought the New York World in 1883. He changed it from a traditional newspaper into a very exciting one overnight. He added lots of illustrations and he told his reporters to write articles on every crime they could find. And they did. One of them-a woman reporter, even pretended she was mad and was sent to a hospital. She then wrote many articles about the poor treatment of patients in those hospitals where mad men were kept.
In 1895, Hearst came to New York from California. He wanted the Journal to be more exciting than the World. He also wanted it to be cheaper, so he lowered the price to a penny. Hearst attracted attention because his newspaper headings were bigger than anyone else’s. He often says, “Big print makes big news.”
Pulitzer and Hearst did anything they could to sell newspapers. For example, Hearst sent Frederic Remington, the famous illustrator, to draw pictures of the Spanish-American War. When he got there, he told Hearst that no fighting was going on, Hearst answered, “You provide the pictures. I’ll provide the war.”
1.What kind of news did American newspapers carry 130 years ago?

Travelers in America who want to experience the Wild West can now go to a holiday in the old style to see how the American pioneers traveled and lived.
Today’s travelers go by horse wagon like the old-time. They set up camp at night under the stars and learn to cook their meals over fires. They also learn to lead herds of cattle with present-day cowboys and try to bring wild horses into a corral (畜栏). For those who just want to pretend half way, the special holidays offer the chance to “rough it” during the day in the wagons but sleep at night in the comfort of fan air-conditioned ranch (牧牛场) complete with swimming pool, sauna and tennis courts.
In Wyoming the holiday makers will travel by wagon past ghost towns and cemeteries where pioneers and wild cowboys were buried. The route goes along the same track as the Pony Express riders who braved attacks from Indians and robbers to get the mail through to the Wild West. High Island Ranch in Wyoming at the foot of the Rocky Mountains is also an ideal place to go trout fishing and to ride wild horses. In Colorado, the modern-day pioneers can stay at Randy George’s ranch and try their hand at breaking-in horses and branding (打烙印) cattle. In New Mexico there will be a chance to help in driving cattle to their new summer pastures (牧场). Trips last for a week so those taking part get a chance to get a feel for the Wild West as it really was.
