Every year thousands of tourists visit Pompeii, Italy. They see the sight that Pompeii is famous for—its stadium and theaters, its shops and restaurants. The tourists do not, however, see Pompeii’s people. No one has lived in Pompeii for almost 2,ooo years.
Once Pompeii was a busy city of 22,000 people. It lay at the foot of Mt Vesuvius, a grass-covered volcano. Mt Vesuvius had not erupted for centuries, so the people of Pompeii felt safe. But they were not. In August of the year 79 AD, Mt Vesuvius erupted. The entire top of the mountain exploded, and a huge black cloud rose into the air. Soon stones and hot ashes began to fall on Pompeii. When the eruption ended two days later, Pompeii was buried under 20 feet of stones and ashes. Almost all of its people were dead.
For centuries, Pompeii lay buried under stones and ashes. Then in the year 1861, an Italian scientist named Ginseppe began to uncover Pompeii. Slowly, carefully, Ginseppe and his men dug. The city almost looked the same as it had looked in 79 AD. There were streets and fountains, houses and shops. There was a stadium with 20,000 seats. Perhaps the most important of all, there were everyday objects, which tell us a great deal about the people who lived in Pompeii. Many glasses and jars had some dark blue color in the bottom, so we know that the people of Pompeii liked wine. They liked bread too; metal bread pans were in every bakery. In one bakery there were 81 round, flat loaves of bread—a type of bread that is still sold in Italy today. Tiny boxes filled with a dark, shiny powder tell us that women liked to wear eye-makeup.
Ginseppe has died, but his work continues. One-fourth has not been uncovered yet. Scientists are still digging, still making discoveries that draw the tourists to Pompeii. Why do large number of people come to Pompeii each year?
A.To visit the volcano. | B.To shop and eat there. |
C.To watch sports and plays. | D.To see how Pompeiians lived. |
Why did the city uncovered look almost the same as it had looked in 79 AD ?
A.Because Ginseppe and his men dug it slowly and carefully. |
B.Because the city was buried alive and remained untouched. |
C.Because scientists successfully rebuilt the city with everyday objects. |
D.Because nobody had lived in the city ever since the volcano erupted. |
What do we know about the Pompeiians who lived 2,000 years ago?
A. They lived more or less the same as Italians now do.
B. They liked women wearing all kinds of makeup.
C. They enjoyed a lazy life with drinking and eating.
D. They went back to Pompeii after the eruption in 79 AD.
Exercise is an important part of a healthy life. It reduces your risk of heart attack and is a good way to control body weight. It is also something you can do with other people, which can be great fun. So, it is important to find time to exercise and be healthier. As well as making time to exercises, another way is to build it into the natural rhythm (节奏) of your day.
· Go for a walk on your lunch break.
Try to find at least three different ways and change them throughout the week. It
might even be possible to find a place to walk inside, for those bad weather days.
· Talk to your employers about improving health at work.
Encourage your workers to cycle to and from work. You might also be able to
encourage them to set up a gymnasium. Sell the idea by pointing out that doing so
will improve productivity (生产率), and make workers happy.
· If you are a student.
Go for walks with friends to talk about your studies. Spend some time in the learning
resource centre reading about sport, exercise and health. The more you know, the
more choices you will have about how to be physically active. Most colleges have
sport and exercise programs that students can take part in. Find out which activities
are being held, and try those you think you might enjoy.
Workers are advised to cycle to and from work to ________.
A.make themselves realize the importance of health |
B.work better and bring pleasure to themselves |
C.make themselves become much stronger |
D.reduce the time spent in walking to work |

An early invention by Albert Einstein has been rebuilt by scientists at Oxford University. They are trying to develop an environmentally friendly refrigerator that runs without electricity.
We all know that modern fridges cause damage to the environment. They work by using a kind of man-made greenhouse gas called Freon (氟里昂), which is far more damaging than carbon dioxide.
Now Malcolm McCulloch, an electrical engineer at Oxford, is leading a three-year project to develop appliances that can be used in places without electricity.
His team has completed a prototype (样机) of a fridge patented in 1930 by Einstein. It used only pressurized gases to keep things cold. The design was partly used in the first refrigerators, but the technology was dropped when more efficient compressors (压缩机) became popular in the 1950s. That meant a switch to using Freon.
Einstein's idea uses butane (丁烷) and water and takes advantage of the fact that liquids boil at lower temperatures, when the air pressure around them is lower.
"If you go to the top of Mount Qomolangma, water boils at a much lower temperature than it does when you're at sea level and that's because the pressure is much lower up there," said McCulloch.At one side is the evaporator (蒸发器), a bottle that contains liquid butane. "If you introduce a new vapor above the butane, the liquid boiling temperature decreases and, as it boils off, it takes energy from the surroundings to do so," says McCulloch. "That's what makes it cold."
The gas fridges based on Einstein's design were replaced by Freon-compressor fridges partly because Einstein's design was not very efficient. But McCulloch thinks that by changing the design and replacing the types of gases used it will be possible to quadruple (翻两番) the efficiency.
However, McCulloch's fridge is still in its early stages. "It's very much a prototype," he said. "Give us another month and we'll have it working.". According to the passage, an early invention by Albert Einstein _______.
A.has been rediscovered because it costs much less and works more efficiently |
B.is being redesigned because it could be used in places without electricity |
C.has just been found to be energy-saving and environmentally friendly |
D.will be fully made use of and become the fridge of the future |
.Which of the following is TRUE according to the text?
A.Freon was used in fridges long before the 1950s. |
B.Freon is what makes current fridges big polluters. |
C.McCulloch thinks he could improve Einstein's design by using other types of vapors. |

A latest national survey has found that over half of China's netizens are suffering from various mental problems although some 62 percent of them claim at the same time that they are happy on the whole anyway.
This is the result of China's first White Paper on Netizens' Health Conditions issued on Wednesday by 39.net, China's largest authoritative website on health sciences. It is the first most comprehensive health survey on netizens' health situation ever conducted in China in ten years' time. The white paper came out after two months of online and offline research that involved over 150 thousand netizens, covering topics and questions on health knowledge, mental situation, sense of health, and living habits.

If you look up the word “create” in the dictionary , you will find it means “to bring into being, to cause to exist something each of us does daily”.
We are creative whenever we look at or think about something in a new way First, this includes an awareness of our surroundings.It means using all of our senses to become aware of our world.This may be as simple as being aware of color and texture(质地),as well as taste, when we plan a meal.Above all, it is the ability to notice things that others might miss.
A second part of creativity is an ability to see relationships among things.If we believe the expression, “There is nothing new under the sun, the creativity is remaking or recombining(重组) the old in new ways.”For example, we might do this by finding a more effective way to study or a better way to arrange our furniture, or we might make a new combination of camera lenses and filters to create an unusual photograph.
A third part of creativity is the courage and drive to make use of our new ideas, to ask for them to achieve some new results.To think up a new idea is one thing; to put the idea to work is another.
