World Expo 2010 Shanghai China is to be staged in Shanghai from May 1 to October 31, 2010. If you plan to visit the Shanghai Expo this summer, China Pavilion(馆)is a must - see area for you.

China Pavilion, which is called Oriental Crown, is located at the center of the Expo site. Standing 63 meters tall, the China Pavilion takes the shape of an emperor's crown, with the upper layers larger than the lower ones. Covering 160,000 square meters in floor space, the pavilion is made up of a national hall and a regional(宗教的  ) hall. Buildings on the China Pavilion began on Dec. 18, 2007. The design of the China Pavilion was picked from a total of 344 designs put for??ward by Chinese from around the world. The pavilion has both traditional and modern features, which helps devel??op the theme of the 2010 Expo; "Better City, Better Life. For example, it is red in appearance, which covers the  traditional Chinese culture, and it is green indoors, with the use of energy - saving techniques. The Shanghai World Expo is expected to attract 70 million visitors from across the globe. It is estimated that 400,000 people will visit the Expo and its 140 pavilions every day during the period, but the China Pavilion is only able to receive about one tenth of the total. How to hold so many people in the pavilion remains a tough task. Luckily, the China Pavilion is built as a permanent(长久的) landmark.

During the Expo, the main structure(结构  ) will be used for an exhibition based on the theme of “ Chinese wisdom in urban （城市）development” by explaining the values of harmony（和谐   ）, nature and spirit. The three - story pavilion has three sections. The top floor's “Footprint of the East” will show some of the changes in Chinese cities. There, you can see a film which shows how Chinese cities have changed, especially in the past 30 years. According to Lu Chuan, director of the film, the scenery is like something from Lord of the Rings. On the second floor, “Journey of Wisdom” will explain China's four great inventions.  And the ground's “ Blossoming” City will display scenes from cities of the future.

Which of the following words can be used to describe the China Pavilion?

A. Tiny.  B. Imagination   C. Foreign   D.  Environment - friendly.

The China Pavilion can receive________visitors at most per day.

A. 20,000     B. 40,000    C.  100,000   D. 400,000        

We can infer(推断   )that________.

A. Some foreign friends took part in the designs of the China Pavilion

B. You can continue to visit the Japanese Pavilion after the Expo is over

C. China Pavilion will be pulled down after the World Expo 2010 is over

D. China Pavilion will continue to be open to visitors after the Expo is over

On the second floor, you can________.

A. enjoy a film about the changes of cities in China

B. learn what Shanghai looked like in the 1920's

C. find out how paper was invented

D. see how Chinese cities will look like in the future

Before a new type of airplane goes into service, every part of it is tested again and again. But there are two tests that are more important than all the others.

The first is called the " tank(贮水池) test". A modem airplane must fly very high in the sky. Air must be pumped into the plane so that the passengers can breathe. The metal structure (结构)of the plane has to be very strong for this reason. When the plane is filled with air, the air presses against the skin of the plane inside. The pressure (压力) on a small window is like a huge foot that is try­ing to get out. If a small part of the plane were to fail, the plane would explode (爆炸)in the sky. To test the structure of the plane, the plane is lowered into a huge tank or container of water. Then it is filled with air.  The pressure inside the plane is greater than it ever will be when it is high up in the air. Finally, there is an explosion. This does not cause so much damage inside the water tank as it would anywhere else. Engineers can discover which part of the plane has broken. Then that part is made stronger. 

The most dangerous test happens when the new plane is going through test flights in the air. The pilot must find out exactly what happens when the engines (发动机) are all shut off at once. The plane begins to fall like a stone. It is the pilot’s job to find out how he can get control of the plane again. These two tests are examples of how planes are made safe before they ever carry passengers.
