The 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, the

China Pavilion is a must-see area for you.

The China Pavilion, which is called Oriental Crown

(东方之冠), 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 consists of a national hall and a regional hall. Construction on the China Pavilion began on Dec. 18, 2007. The design of the China Pavilion was picked from a total of 344 designs put forward by Chinese from around the world. The pavilion possesses both traditional and modern features, which helps develop the theme of the 2010 Expo “Better City, Better Life”. For example, it is red in appearance, which contains the elements of 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 accommodate so many people in the pavilion remains a tough task. Luckily, the China Pavilion is built as a permanent landmark.

During the Expo, the main structure will be used for an exhibition based on the theme of “Chinese wisdom in urban development" by explaining the values of harmony, 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 The 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. Round.          

C. Foreign.           D. Environment-friendly.

The China Pavilion can receive           visitors at most per day.

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

We can infer that          .

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

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

C. you can continue to visit the Japanese Pavilion after the Expo is over

D. some foreign friends took part in the designs of the China Pavilion

On the second floor of the China Pavilion, you can          .

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

B. learn what Shanghai looked like in the 1920s

C. find out how paper was invented

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

The dream of flying like Buzz Lightyear never dies. For years, space-age inventors have tested one wearable jet pack after another. And time after time, the designs have been grounded by dangerous fuels, excessive weight, or very loud noise levels. Now a Canadian inventor has sidestepped those weaknesses with an aquatic jet pack. Designed for travel over lakes or oceans, it’s driven by pressurized water, not burning rocket fuel.

When Raymond Li first told the idea for the aquatic jet pack to his friends, they said he must be nuts. How could a jet pack carry that much water? Its thrust-to-weight rate would be so low and it would never become airborne. Thrust-to-weight rate is a measure of the forward force produced compared with the weight of the vehicle. A vehicle with a low thrust-to-weight rate is relatively heavy for the amount of force it generates.

Li's genius idea was to place the jet pack’s engine and its water pump in a separate boat. The pump would draw water from the lake the boat was floating on. It would then force the water under pressure through a hose connected to the jet pack. The hose would be long enough to let the pack go up as high as 8.5 meters (28 feet) in the air.

Today, Li's invention, the Jetlev-Flyer, is ready to go into production. The pack itself, complete with jet nozzles (管嘴) and handlebars, weighs just 14 kilograms. The boat is a floating pod. To take off, the operator hits a trigger on a handlebar, which starts the pump, and then turns the throttle. Two streams of high-velocity water shoot through the hose and out the nozzles, lifting the operator into the air. The operator hovers there or pushes down on the handlebars, zooming forward at speeds of up to 64 kilometers per hour, pulling the pod behind.

All the following factors contribute to the failure of inventing a wearable jet pack EXCEPT ______.

A. excessive water     B. unbearable noise    C. unsafe fuels   D. too much weight 

The underlined word “sidestepped” in Para. 1 most probably means ________.

  A. improved          B. reduced         C. avoided         D. solved

Raymond Li’s friends found his idea for the aquatic jet pack was ________.

  A. exciting           B. crazy          C. realistic         D. creative

Which of the following is TRUE according to the passage?

  A. His friends encouraged him to do the invention.

  B. He put the engine and its water pump in the same boat.

  C. The success of his invention lies in his bravery.   

  D. His invention finally succeeded and will go into production.

Which is the right order to make the Jetlev-Flyer take off?

  a. The throttle is turned.                  b. The operator is lifted into the air.

  c. A trigger is hit.                       d. Two streams of water shoot out.

The pump is started.

A. c, e, a, d, b          B. c, e, a, b, d            C. e, c, d, b, a          D. e, a, c, d, b

阅读下面短文,根据第73至第75小题的具体要求,简要回答问题。

Every January, Breckenridge hosts the International Show Sculpture Championships. Fourteen teams travel from all over the world to

Switzerland to compete. Teams sculpt for sixty-five hours over five days. Each team hopes that when the time is up, its sculpture will be judged the best

As the championship begins, the fourteen teams are faced with huge blocks of snow that weigh twenty tons each. The sculptors bring out their

vorite tools that work best on the hard iced snow, but they are not allowed to employ tools that use electricity.

Most teams are inspired by what they have seen in daily life. For example, one team carved a teapot with tea pouring out. Another team sculpted a little cat on its hind feed(后脚) reaching into a fish bowl complete with water ripples(涟漪) and a crab(螃蟹) trying to attack the cat. In 2006, Team USA sculpted a golden dog looking at its image reflected in a mirror. To create the effect that the little dog saw its reflection in the glass, the artists carved two dogs facing each other with their paws (脚爪) touching.

As the final hours of the competition tick by, exhausted team members add last-minute details. They use small brooms to brush off snow caught in tiny holes. One team member counts down the last five minutes while others are busy cleaning up the tools. If they leave any tools behind, they will be out. When the whistle blows, everyone must step away from the sculpture. The judges then vote on creativity, technical skill, and visual impact(视觉效果) of the designs

In 2006, Team USA took firs place for their golden dog sculpture titled “Discovery”。 But the competition is not just about medals and ribbon. “It‘s not about the prize,” said Rob Neyland, Team USA’s captain. “It‘s about touching the audience.”

Every year, as the championship ends, each team is already dreaming of the next masterpiece it will design.

What kind of tools are the sculptures NOT permitted to use? (回答词数不超过6个)

What gives the sculptors ideas for their creative work? (回答词数不超过9个)

Why did Team USA win the competition in 2006? (回答词数不超过15个)

Dear Sirs,

Your shipment(装运)of twelve thousand“Smart”watches was received by our company this morning.However,we wish to make a number of complaints concerning the serious delay in delivery and your failure to carry out our instructions.   

It was stressed from the beginning that the delivery date had to be less than six weeks. While we appreciate that delays in production are occasionally unavoidable.We must point out that the major reason why the order was placed with your company was that we were assured by you that your existing stocks ensure immediate shipment.Late delivery of the goods has caused us to disappoint several of our most valued customers.and is sure to have a negative effect on future orders.

The second complaint concerns the difference in colour.Only half the watches in the delivery received are of the colours we ordered.Our Hong Kong agent assures us that she stressed to you the importance of following our instructions.Since we consider there to be only a limited market in this country for watches of other colours.Any watches that are not of the specified colours will , of course, be returned to you.   

We are also somewhat concerned about the rather poor quality of the goods received.since it is obvious that the watches that finally arrived have been produced from inferior materials and have been made to a lower standard than those in the sample.We have also found that a number of the watches do not appear to be functioning.We should like to point out that we feel this matter to be entirely your responsibility.

As a result of the above problems,therefore,we feel that the most suitable course of action is to return to you unpaid any of the goods considered unsatisfactory,and to deduct(扣除)any costs from our final settlement.We shall also be forced to reconsider whether any further orders should be placed with your company.

We look forward to your immediate reply.

Yours sincerely,

John Smith
