Temperature is measured by means of a thermometer (温度计). One general form of thermometer depends upon the fact that most solids and liquids expand as their temperature rises. There are one or two exceptions. There is, for instance, a kind of steel called invar (from “invariable”) which does not change its dimensions as temperature changes; it is valuable for making pendulums (钟摆), since, if the length of a pendulum changes, its time of vibration changes. It is also used for making very accurate measuring scales. In both cases, then, changes of atmospheric temperature have no effect if invar is used.
Another exception is that very odd liquid, water, which has many strange properties (特性). As water gets colder it contracts (收缩), which is ordinary behavior, until it reaches the temperature of 30℃. above freezing point. After that, as it gets colder, it expands. This is fortunate---for considering the freezing of a pond. As the water on top gets colder, it shrinks; and so, volume for volume, it becomes heavier and sinks. This goes on until all the pond is at 30℃, but after that, as the water becomes colder it expands. Therefore the colder water stays on top and freezes, covering the pond with ice. If the water went on contracting down to the freezing point, the pond would become a solid block of ice in the end. This would not worry people who live in hot climates, but it would be very serious for those who live in cold climates, especially for those who want to break the ice and catch fish which live in the cold water beneath. Invar is valuable for making pendulums because _______.
| A．it can hardly change its shape or size as temperature changes. |
| B．it will change its dimensions without the change of temperature. |
| C．its time of vibration doesn’t change if its length changes. |
| D．its time of vibration does not change if its length changes. |
As water gets colder after reaching the temperature of 30℃. it will _______.
| A．contract | B．shrink | C．expand | D．freeze |

| A．Only invar can be used to make a thermometer. |
| B．Only water can be used to make a thermometer. |
| C．Both invar and water can be used to make a thermometer. |
| D．Neither invar nor water can be used to make a thermometer. |

Imagine being the only person in the Forbidden City. You could stay there all day without swarms of people crowding around. You'd be able to look at the ancient treasures without worrying about other visitors pushing you for a better view. Well, in two years time you'll be able to have such an experience, just like the former emperors used to. The only difference is that your Forbidden City fun will be online.
Thanks to new technology, a virtual tour of the Forbidden City will be available online by 2008. The project － jointly driven by the Palace Museum and computer company IBM － aims to help teenagers around the world become more interested in Chinese culture. The project will offer an interactive, three-dimensional view of the palace. The virtual tour will provide images from all over the 780,000-square-metre palace.
"The Palace Museum is a big book; there are always places you haven't read about," said Hu Chui from the museum. There are many rooms closed for protection. But the virtual platform breaks the boundaries of time and space, meaning visitors can see whatever they want. "The interaction and games content in the virtual tour will attract more young people to understand and love our cultural heritage," added Hu.
In the virtual tour, historical figures will actually talk to visitors and answer their questions. The stories behind the buildings and treasures will also be told. "The online environment, presented in both Chinese and English, enables visitors to experience the culture and stories of the museum," said James Yeh, an IBM official.

In 1879, a group of explorers made an incredible find. They discovered paintings of remarkable beauty on the walls of a cave in Spain. Some scientists believed that these paintings were created by early humans from the Stone Age, between ten and thirty thousand years ago. Other scientists and the public did not believe the claim, but over the years, it was proven correct. Our ancestors had incredible artistic talents.
Most of the cave art that has been discovered has been found in Spain and France. A smaller number of such caves are located in Italy, Portugal, Russia, and other countries. Scientists believe that many more caves will be discovered in the coming years, and are concentrating their efforts on Africa and the area between Europe and Asia. These two regions of the world were, populated first by humans.
Cave art was carved or painted on the walls and roofs of caves, usually near the entrance. The entrance area was probably chosen to take advantage of daylight and to allow many people to view the paintings. In some cases, the art appears much deeper in caves and requires artificial light. Evidence suggests that the artists used torches or shallow bowls in which animal fat was burned.
9.What was the response of general public to the discovery of cave art made by Stone Age people?

Mark was walking home from school one day when he noticed the boy ahead of him had stumbled over something and dropped all of the books he was carrying along with two sweaters, a baseball bat, a glove and a small tape recorder. Mark knelt down and helped the boy pick up the scattered articles. Since they were going the same way, he helped to carry part of the burden. As they walked Mark discovered the boy’s name was Bill, that he loved video games, baseball and history, and that he was having lots of trouble with his other subjects and that he had just broken up with his girlfriend.
They arrived at Bill's home first and Mark was invited in for a Coke and to watch some television. The afternoon passed pleasantly with a few laughs and some shared small talk, then both graduated from junior high school. They ended up in the same high school where they had brief contacts over the years. Finally the long awaited senior year came and three weeks before graduation, Bill asked Mark if they could talk.
Bill reminded him of the day years ago when they had first met. "Did you ever wonder why I was carrying so many things home that day?" asked Bill. "You see, I cleaned out my locker because I didn't want to leave a mess for anyone else. I had stored away some of my mother's sleeping pills and I was going home to commit suicide. But after we spent some time together talking and laughing, I realized that if Ihad killed myself, I would have missed that time and so many others that might follow.

The Great Wall of China, one of the greatest wonders of the world, was enlisted in the World Heritage by the UNESCO in 1987. Just like a gigantic dragon, the Great Wall winds up and down across deserts, grasslands and mountains, stretching about 6,700 kilometers from east to west of China. With a history of more than 2,000 years, some parts of the Great Wall are now in ruins or even entirely disappeared. However, it is still one of the most appealing attractions around the world.
No one can tell for sure when the building of the Great Wall was started, but it is popularly believed that it originated as a military fortification(要塞) against intrusion by tribes on the borders during the earlier Zhou Dynasty. Late in the Spring and Autumn Period, some states extended the defence work to prevent the attacks from other states.
It was not until the Qin Dynasty that the separate walls were connected to form a defensive system by Emperor Qin Shi Huang. After the emperor unified the country in 214 BC, he ordered the construction of the wall. It took about ten years to finish and the wall stretched from Gansu Province to Jilin Province. The wall not only served as a defence in the north but also symbolized the power of the emperor.
Further construction also experienced several dynasties. The present Great Wall in Beijing is mainly remains from the Ming Dynasty. Today, the Great Wall has become a must-see for every visitor to China. Few can help saying “Wow” when they stand on top of a beacon tower and look at this giant dragon. It has become a national pride of Chinese people. The underlined word “appealing” probably means “______”.
