Recently some American scientists have given a useful piece of advice to people in industrialized nations．They say people should eat more of the same kind of food eaten by humans living more than 10,000 years ago． {#blank#}1{#/blank#}

    The scientists say that the human life has changed greatly．Our bodies have not been able to deal with these changes in lifestyle and this had led to new kinds of sicknesses． {#blank#}2{#/blank#} So they are called “diseases of civilization”．Many cancers and diseases of the blood system are examples of such diseases.

    Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none． {#blank#}3{#/blank#} However, a change in food is one of the main differences between life in ancient times and that of today.

    Stone Age people hunted wild animals for their meat, which had much less fat than domestic ones．They ate a lot of fresh wild vegetables and fruits．They did not have milk or any other dairy products, and they made very little use of grains． {#blank#}4{#/blank#} We eat six times more salt than our ancestors．We eat more sugar．We eat twice as much fat but only one third as much protein and much less vitamin C.

    {#blank#}5{#/blank#} But scientists say that we would be much healthier if we eat much the same way the ancient people did, cutting the amount of fatty, salty and sweet food.

A．Stone Age people lived a simple life.

B．But today, we enjoy eating a lot of these.

C．In that case, they would live much healthier.

D．Ancient people also got lots of physical exercise.

E．These new sicknesses were not known in ancient times.

F．People today probably don't want to live like our ancestors.

G．Modern people used to suffer from “diseases of civilization”.

    England's highest main-line railway station is in serious trouble, deserted and unmanned since it was officially closed in 1970, Dent, located high in the hills of Yorkshire, wakes up on six summer weekends each year, when a special train unloads walkers, sightseers and people who simply want to catch a train from the highest station to its platforms.

    But even this limited being may soon be brought to an end. Dent station located on the Settel to Carlisle railway line, is said to be surrounded by the most beautiful scenery in the country. But no amount of scenic beauty can save the line because of the British Rail's money problems.

    It is now an open secret that British Rail sees no future for this railway line. Most of its trains disappeared some time ago. Bridges, built a century ago, are falling down. It is not alone. Half a dozen railway routes in the North of England are facing a similar threat. The problem is an old system and an almost total lack of cash to repair it. Bridges and tunnels are showing their ages, the wooden supports for the tracks are rotting（腐烂） and engines and coaches(车厢) are getting old.

    On main lines between large cities, the problem is not too bad. There lines still make a profit and cash can be found to keep them in good condition. But on the country branch line, the situation is different. As track wears out, it is not replaced. Instead speed limits are introduced, making the journey longer than necessary and discouraging travelers.

    If a bridge is dangerous, there is often only one thing for British Rail to do: go out and find money from another places. This is exactly what it did a few months ago when a bridge at Bridling station was threatening to fall down. Repairs were calculated at 200,000 pounds just for one bridge, so British Rail was pleased, and rather surprised when two local councils(理事会) offered half that amount of money.

    Kung fu is one of the most popular topics of discussion among foreigners talking about China. As a discipline of kung fu with the largest number of practitioners in China, Tai Chi is gaining popularity worldwide. Tai Chi is sweeping the world thanks to its deep cultural roots and the health benefits coming from practicing it.

    The philosophy of Tai Chi features the concept of yin and yang, which is typical of Confucianism and Taoism. Tai Chi also takes in ideas from traditional Chinese medicine, including anatomy (解剖学) and physiology (生理学). It is a practice that couples hardness with softness, and it is a perfect example of traditional Chinese culture.

    Through lasting practice, learners begin to feel the positive impact (影响) of Tai Chi on their health. Unlike kung fu practices that focus on attacking and defending against enemies, Tai Chi focuses more on shaping good characters and keeping fit. By practicing Tai Chi, people will feel an improvement in their physical and psychological health by promoting a balance between yin and yang within their bodies. This is similar to Western medicine's improving people's self-healing ability and immune system.

    Tai Chi is playing an important role in presenting Chinese culture to the rest of the world, acting like a bridge between China and other countries. Recent years have seen a lot of international communication on Tai Chi. In provinces like Hebei, Henan, Shanxi and Shaanxi, where Tai Chi teaching and learning are particularly active, local governments and non-governmental institutions often organize activities and competitions for learners and fans to attend and participate in. Large sporting events hosted by China such as the Asian Games and Olympics have featured Tai Chi performances or contests. These activities have opened a window for the outside world to know more about Tai Chi, paving the way for its overseas wide spread.

    Today, Tai Chi not only belongs to China, but also to the whole world and to everyone who loves it.

    A newspaper reporter's job can be very interesting. He meets all types of people and lives quite a busy life. He is on the rush for news all the time, then after several years he may get a desk job, and life becomes a bit more settled. Let's look at his work a little more closely. In a day he may have to interview the prime minister of a foreign country, and the next day he may be writing about a football match. Sometimes he may be so busy that he has hardly any time to sleep. And at other times he may go on for days looking out for news materials yet return empty-handed.

    In the beginning, a reporter has to cover a very wide field. After the early years he becomes more specialized in his work. For example, he may finally be asked to write only on court cases or politics or sports. Some reporters may become so specialized that they are asked only to write on a special thing: horse racing, for example. In most newspaper houses there is at least one special racing correspondent. Some newspapers have book reviews. Their job is delightful. They read the latest book and then write reviews on the ones they like. Then there are those who write on films, so they get to see them even before they are shown in the cinema. How lucky, you would say!

    A reporter's job can also be very dangerous. A number of them have died rushing from one assignment to another, and if there is a flood or a riot(暴) they may get hurt or even be killed. Three years ago there was a reporter whose camera was smashed by a group of men, because they were angry with him for taking their picture. Dangerous or not, one thing is certain, and that is, their job is never dull!

    First aid is defined as the emergency care given to a sick or injured person. The goals of first aid are to prevent death and to prevent injuries from becoming worse. Each emergency condition is different. However, the following rules apply to any kind of emergency.

    Be aware of your limitations. Do not try to do more than you are able to. Nor should you do things if you are unfamiliar with them. Do what you can under the conditions at the time.

    Stay calm. Acting calmly will help the victim feel safe.

    Take a quick look to see if the victim is bleeding, and if there is a pulse.

    Keep the victim lying down and do not move him or her. You could make an injury worse if you move the victim.

    Call for help or ask someone to make the EMS system (急救系统) start.

    Keep the victim warm. Cover the victim with a blanket. Coats and sweaters can be used if a blanket can not be found.

    Reassure (使……安心) the victim. Explain what is happening and that help has been called.

    Do not give the victim any food or fruits.

    Keep the bystanders (旁观者) away from the victim. Bystanders want to have a look, offer advice, and say something about the victim's condition. The victim may believe that the condition is worse than it really is.
