Walking will be banned on escalators as part of a trail designed to reduce congestion（拥堵） at some of the country's busiest stations．
In the first move of its kind，all travelers will be forced to stand on both sides of escalators on the London Underground as part of a plan to increase capacity（容量） at the height of the rush hour．
A six﹣month trial will be introduced at Holborn station from mid﹣April，eliminating the rule of standing on the right and walking on the left．The move，imitating a similar structure in Far Eastern cities such as Hong Kong，is designed to increase the number of people using long escalators at the busiest times．it could be expanded across the Tube network in coming years．
According to London Underground，only 40percent of travelers walk the full length of long escalators，leaving the majority at the bottom as they wait to get on to the"standing"side．
A three﹣week trial at Holborn last year found that the number of people using escalators at any one time of could be raised by almost a third．Peter McNaught，operations director at London Underground，said："It may not seem right that you can go quicker by standing still，but our experiments at Holborn have proved that it can be true．This new six﹣month trial will help us find out if we can influence customers to stand on both sides in the long term．"
Holborn has one of the longest sets of escalators on the Underground network at 23.4high．Tube bosses claim that capacity was limited because so few people wanted to walk up﹣meaning only one side was used at all times．Research has shown that it is more effective use of escalators over 18.5to ban walking．
The previous trial found that escalators at the station normally carried 2，500people between 8：30am and 9：30am on a typical day，rising to 3，250during the researching period．
In the new trial，which will be launched from April 18，one of three"up"escalators will be standing only，with a second banning walking at peak times．A third will remain a mix of walking and standing．

The huge Florida wetland known as the Everglades is a slow-moving river 80 kilometres wide but only a few centimeters deep. People call the Everglades a “river of grass” because sawgrass covers most of it. Sawgrass is not really grass. It is a plant that has leaves edged with tiny sharp teeth that can easily cut through clothes—and skin!
Travel in the Everglades is difficult. You cannot walk through shallow water because the sawgrass will cut you. The water is too shallow for regular boats. So, we use an airboat. An airboat is a flat, open boat. Like an airplane, it has a big propeller to move it. The propeller is fixed on the rear of the boat. It makes a tremendous noise, but it does the job. The boat skims along the water’s surface. Although we can still get lost in an airboat, at least we are above the alligators(短吻鳄).
While hundreds of different kinds of animals live in the Everglades, the most famous is surely the alligator. Once endangered, alligators are now protected within Everglades National Park. Visitors are likely to see them both on land and in water.
For a long time, dangers have threatened the Everglades. Around 1900, some people felt this precious wetland should be drained (排干). They said it was just a big swamp and not good for anything. In the 1920s, there was a land boom in Florida. People wanted to build homes everywhere, including in the Everglades. They built canals, levees (防洪堤), and other water systems that stopped the rivers flowing into the Everglades. Factories were built near rivers that flowed into the wetland. These factories dumped poisonous waste that damaged the Everglades ecosystem.
People are now working to preserve the Everglades National Park for the future. Right now, one big problem is the paperbark tree. This tree is an invader from Australia.
Paperbark trees soak up a lot of water. In the early 1900s, people brought them to Florida because they thought they would help drain the Everglades. However, the invaders adapted too well. Paperbark trees have taken over hundreds of thousands of acres of the Everglades and killed other trees. Scientists are cutting down these invaders or spraying them with herbicides (除草剂) to kill them.Which helps to explain why it is difficult to travel in Everglades?
| A．Airboats may make a very big noise. |
| B．You may get lost when passing through. |
| C．Paperbark trees soak up too much water there. |
| D．Many different kinds of animals are to be protected. |
Why do people use airboats instead of normal boats?
| A．They have big propellers to move them faster than alligators. |
| B．The propeller makes loud noise so as to scare alligators. |
| C．Their flat bottom can skim along the water surface. |
| D．They can watch alligators without hurting them. |
The following measures were taken to drain the Everglades except that people______.
| A．built canals and levees to stop the rivers flowing into Everglades |
| B．built factories near rivers that flowed into the wetland |
| C．brought Paperbark to soak up water in Everglades |
| D．are cutting down these Paperbark trees |
The underlined word "invader" probably means something______.
| A．that moves in from another place |
| B．that enters and takes control |
| C．that has been brought in |
| D．that is in danger |
That “Monday morning feeling” could be a crushing pain in the chest which leaves you sweating and gasping for breath. Recent research from Germany and Italy shows that heart attacks are more common on Monday mornings and doctors blame the stress of returning to work after the weekend break.
The risk of having a heart attack on any given day should be one in seven, but a six-year study helped by researchers at the Free University of Berlin of more than 2,600 Germans showed that the average person had a 20 per cent higher chance of having a heart attack on a Monday than on any other day.
Working Germans are particularly not protected against attack, with a 33 per cent higher risk at the beginning of the working week. Non-workers, by comparison, appear to be no more at risk on a Monday than any other day.
A study of 11,000 Italians proved 8 am on a Monday morning as the most stressful time for the heart, and both studies showed that Sunday is the least stressful day, with fewer heart attacks in both countries.
The findings could lead to a better understanding of what is the immediate cause of heart attacks, according to Dr Stefan Willich of the Free University. “We know a lot about long-term risk factors such as smoking and cholesterol（胆固醇）but we don’t know what actually causes heart attacks, so we can’t give clear advice on how to prevent them,” he said.
Monday mornings have a double helping of stress for the working body as it makes a rapid change from sleep to activity, and from the relaxing weekend to the pressures of work.
“When people get up, their blood pressure and heart rate go up and there are hormonal（内分泌）changes in their bodies,” Willich explained. “All these things can have an unfavourable effect in the blood system and increase the risk of a clot（血凝块）in the arteries（动脉）which will cause a heart attack.”
“When people return to work after a weekend off, the pace of their life changes. They have a higher workload, more stress, more anger and more physical activity,” said Willich.Monday morning feeling, as this passage shows, .
| A．is not so serious as people thought |
| B．is harmful to working people in developed countries. |
| C．is the first killer in Germany and Italy. |
| D．is created by researchers in Germany and Italy |
To protect people from suffering from heart attack, doctors have paid much attention to.
| A．people’s working time |
| B．people’s living place |
| C．people’s diet and lifestyle |
| D．people’s nationalities |
It can be learned from this passage that heart attack has nothing to do with.
| A．blood pressure | B．heart rate |
| C．hormonal changes | D．blood group |
If the researchers give us some advice to avoid Monday morning feeling, what might it be?
| A．Stop working on Monday |
| B．Create a pleasant working environment |
| C．Get up late on Monday morning |
| D．Go to work with a doctor |
Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food ,get enough sleep, and exercise regularly.
Proper nutrition (营养) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”(燃料).Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein (蛋白质) ,like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins (维他命) and minerals. However, don't overeat. It is not helpful to be overweight.
Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little a amount of sleep may even result in a change of personality (人的个性).Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.
Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (寿命).Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.

I was telling my boy Sonny the story of the hare (兔子) and the tortoise (乌龟). At the end I said, “ Son, remember: Be slow and steady (镇定的), and that will win the race. Don’t you think there’s something to learn from the tortoise?”
Sonny opened his eyes wide, “Do you mean next time when I’m entering for the 60-metre race I should wish that Billy, Tony and Sandy would all fall asleep halfway?”
I was shocked, “But the tortoise didn’t wish that the hare would fall asleep!”
“He must have wished that,” Sonny said, “Otherwise how could he be so foolish as to race with the hare? He knew very well the hare ran a hundred times faster than he himself did.”
“He didn’t have such a wish,” I insisted. “He won the race by perseverance (坚忍不拔的), by pushing on steadily.”
Sonny thought a while. “That’s a lie,” he said. “He won it because he was lucky. If the hare hadn’t happened to fall asleep, the tortoise would never have won the race. He could be as steady as you like, or a hundred times steadier, but he’d never have won the race. That’s for sure.”

“Fire! Fire!” What terrible words to hear when one wakes up in a strange house in the middle of the night! It was a large, old, wooden house and my room was on the top floor. I jumped out of bed, opened the door and stepped outside the house. There was full of thick smoke.
I began to run, but as I was still only half-awake, instead of going towards the stairs I went in the opposite direction. The smoke grew thicker and I could see fire all around. The floor became hot under my bare feet. I found an open door and ran into a room to get to the window. But before I could reach it, one of my feet caught in something soft and I fell down. The thing I had fallen over felt like a bundle of clothes, and I picked it up to protect my face from the smoke and heat. Just then the floor gave way under me and I crashed to the floor below with pieces of burning wood all around me.
I saw a doorway in fire, then I put the bundle over my face and ran. My feet burned me terrible, but I got through. As I reached the cold air outside, my bundle of clothes gave a thin cry, I nearly dropped it in my surprise. Then I was in a crowd gathered in the street. A woman in a night-dress and a borrowed man’s coat screamed as she saw me and came running madly.
