early morning in fresh air, because it has many benefits. Firstly, it doesn"t disturb your daily routine activities.Secondly, it does not only help lose weight, but it"s also useful for good health. Thirdly, you won"t get an
excuse that you didn"t get time to go for  your workout due to your tight schedule. It"s scientifically proved
that walking in the early morning to lose weight helps you to burn calories faster than at any time of the day.Having a good morning walk and then a healthy breakfast can help to increase the metabolism (新陈代谢) of your body. As the metabolism increases, you burn more calories.
     The first thing to do is to set up a goal that you want to achieve. Therefore, work out a walking routine.
At first, start walking three times a week, and then slowly increase it to five times a week. It"s advisable not
to overdo walking, as it can have side effects on the body. Here are certain easy steps that you need to
follow when you start your daily walking routine.
     Warm-up is an important activity that is to be done before you start to do any kind of exercise. A light
warmup period of about 15 minutes is enough. It will warm up your muscles and avoid any injury to your
body. Exercising without warmup can be dangerous and must be avoided.
     Make sure that you don"t stop anywhere in between your 30 or 45 minutes" walk. Slow down if
necessary. Stopping in your walk won"t help you. Instead, slowing down your speed will help to burn more calories.
     While walking, take long strides (步伐) and swing your arms in a rhythm.This will use up muscles and
help burn more calories.
     In a word, regularity and correctness in walking is the key to success. Best of luck！

Half an hour of exercise a day can add an extra five years on your life, a ground breaking research has revealed.Health experts said that walking or cycling gently has massive longterm benefits.According to the World Health Organization, research carried out in Britain and Denmark shows that gentle workouts (锻炼) and even housework every day can boost life spans by as much as five years.       The news will provide encouragement for those couch_potatoes to start taking exercise.Britain is in the grip of an obesity epidemic (肥胖症), with just 35% of men and 24% of women taking regular exercise.      "Encouraging people to be physically active every day has so many health benefits, " said Dr.Marc Danzon, WHO regional director for Europe."These include reducing the risk of developing certain diseases and of becoming obese, as well as contributing to physical coordination, balance, strength and mental wellbeing.It is a very costeffective public health tool."      The organization is so concerned that the public is not getting the message on exercise that it will   launch a "Move for Health" campaign to boost public awareness.       "The WHO encourages adults to take at least 30 minutes of moderate physical exercise a day, defined as any body movement that results in energy expenditure (消耗), " said Dr  Danzon."This includes walking, cycling, playing, housework, climbing stairs as well as sports." He added that children should take at least 60 minutes of exercise every day. 1. The underlined phrase "couch potatoes" probably means______. A. lazy bones who spend a lot of time sitting B. people who like eating potatoes C. persons who usually rest on a couch D. players who take exercise with potatoes 2. Taking physical exercise every day benefits one"s health in the following aspects except________. A. strengthening body coordination B. developing certain diseases and becoming obese C. keeping body balance D. keeping fit mentally 3. Which statement is NOT true according to the passage? A. Children should take more physical exercise than adults every day. B. The WHO has tried to improve people"s knowledge about exercise by launching a campaign. C. People with an obesity epidemic in Britain seldom take regular exercise. D. Physical exercise brings the best possible profit to public health at the lowest cost. 4. The passage mainly tells us________. A. how to take exercise   B. what the WHO is C. how to lose weight   D. how to add years to your life

Global warming is the process of earth"s atmosphere heating up. Over the last 100 years, the average temperature of earth"s atmosphere has gone up 1 Fahrenheit. The weather has not changed exactly the same way in every area of the planet. But scientists think that the rise in average temperature is already affecting the earth"s climate.       Many scientists now believe that global warming is caused by cutting down trees, producing more trash, and polluting the environment which are some of the reasons why the temperature has gone up. Many scientists believe that the biggest causes of global warming are new human technologies that release greenhouse gases into the atmosphere.      The greenhouse effect is not new. Certain gases in the atmosphere, like carbon dioxide, nitrous oxide and methane, making it hard for heat energy to go into space. In the past, the climate didn"t change much because nature produced just the right amount of greenhouse gases to deal with it.      Today, most scientists are pretty sure that the rising temperature can"t be blamed on nature. Ever since the industrial revolution in the 1700s, humans have relied on machines for daily life. And many of those machines give off a lot of greenhouse gases. An increase in the release of greenhouse gases from human activities is throwing nature off balance.      The climate is a very complicated thing, but many scientists agree that the rising atmospheric temperature has already damaged the environment. Sheets of ice, called glaciers, are melting in Antarctica and other parts of the globe. As glaciers break off and melt into the oceans, they are adding warm water to the oceans and causing the sea level to rise.      Over the past 100 years, the sea level has risen 6-8 inches around the world. That means land along the coasts is beginning to disappear under water. Bigger and warmer oceans are also adding to other weather problems caused by pollution in the atmosphere. Some places have received more rain, others have had bigger storms and a few areas in the world have experienced unusual droughts. 1. What is mainly talked about in this passage? A. The melting of glaciers.                 B. Global warming.  C. The world"s weather.                   D. The earth"s temperature. 2. What causes global warming according to scientists? A. Human activities.                     B. The nature itself. C. The earth"s atmosphere.                 D. New discoveries 3. From the passage we can see that global warming will bring about _____. A. the pollution in the atmosphere             B. natural disasters C. population pollution                     D. the rise of glaciers

Tongue clicking is an important part of language for some southern African groups. And it could help disabled people control their wheelchairs. The key is a device that is put in the ears and listens for tongue clicks and then translates the sounds into commands for a wheelchair.      Mouth interfaces (接口)that interact with wheelchairs are already common for seriously disabled people. One device that fits within the roof of the mouth houses buttons that can be pressed with the tongue.      "But everything that involves tongue movement requires putting something in the mouth," says Ravi, from the University of Bristol, UK. Besides issues of hygiene (卫生),these devices make it difficult for the user to eat or speak, if they are able to ,while using it. Monitoring tongue movements through the ear avoids these problems.      The new device, a simple microphone that looks like an earphone for listening to music, picks up certain sounds made by four sorts of tongue clicks. The microphone sends the information to a signal processor which sorts out the clicks and passes the information to the wheelchair, where each click type moves the chair in a distinct direction.      Ravi"s group has used the interface to control a virtual wheelchair. They have also used it to control the reaching and grasping movements of a robotic arm. The four tongue clicks can be mastered in a couple of hours, say the researchers. "This is a promising technique," says Jose del R. Millan, who has been working on brain interfaces for controlling wheelchairs at the Swiss Federal Institute of Technology in Lausanne. If it can be combined with real wheelchairs and shown to work reliably it could be very valuable for patients, he says.       The researchers plan to start using real wheelchairs, but in the meantime they are looking at whether the number of commands can be increased by using a microphone in each ear, to get clearer signals to the wheelchairs. "Even if four clicks prove to be the limit, it only takes 0.2 second to detect each sound, so it"s possible to spread high-level commands through combinations of clicking sounds," the researchers say.
1. What plays the most important role in controlling the wheelchair by tongue clicking?
A. The tongue. B. The device. C. The wheelchair. D. the brain.
2. What problem will be caused if mouth interfaces are used to monitor the wheelchair?
A. It is very difficult to operate the device. B. The device is dirty and leads to disease. C. The device makes it difficult for people to eat or speak. D. People are disturbed by the device when listening.
3. What do we know about the new device according to the passage?
A. It is actually an earphone used to listen to music. B. It hasn"t been put into practice to control wheelchairs. C. It can pick up all sounds made by tongue clicks. D. It can give orders where the wheelchair should go .
4. What problem are Ravi and his groups trying to solve now?
A. That the device can"t detect more commands. B. That it needs a long time to detect each sound. C. That it can only combine some easy tongue clicks. D. That it takes a long time for the disabled to learn tongue clicks.
