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.
【小题1】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

【小题2】The underlined word “sidestepped” in Para. 1 most probably means ________.

A．improved

B．reduced

C．avoided

D．solved

【小题3】 Raymond Li’s friends found his idea for the aquatic jet pack was ________.

A．exciting

B．crazy

C．realistic

D．creative

【小题4】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.

【小题5】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

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有一项为多余选项。

A.　Goods for auction (拍卖) sales

　　B.　Definition of bidding

　　C.　Way to sell more goods by auction

　　D.　Auction sales in history

　　E.　Brief introduction to auctions

　　F.　Making a larger profit as an auctioneer

1.______

Auctions are public sales of goods, conducted by an officially approved auctioneer. He asks the crowd assembled in the auction-room to make offers, or “bids”, for the various items on sale. He encourages buyers to bid higher figures, and finally names the highest bidder as the buyer of the goods. This is called “knocking down” the goods, for the bidding ends when the auctioneer strikes a small hammer on a table at which he stands.

2. ______

The ancient Roman probably invented sales by auction, and the English word comes from the Latin auction, meaning “increasing”. The Romans usually sold in this way the goods taken in war. In England in the eighteenth centuries, goods were often sold “by the candle”: a short candle was lit by the auctioneer, and bids could be made while it stayed alight.

3. ______

Practically all goods whose qualities vary are sold by auction. Among these are coffee, skins, wool, tea, furs, silk and wines. Auction sales are also usual for land and property, furniture, pictures, rare books, old china and similar works of art.

4. ______

An auction is usually advertised beforehand with full particulars of the articles to be sold and where and when they can be viewed by potential buyers. If the advertisement cannot give full details, catalogues are printed, and each group of goods to be sold together, called a “lot”, is usually given a number. The auctioneer need not begin with Lot 1 and continue in the order of numbers: he may wait until he notices the fact that certain buyers are in the room and then produce the lots they are likely to be interested in.

5. ______

The auctioneer’s services are paid for in the form of a percentage of the price the goods are sold for. The auctioneer therefore has a direct interest in pushing up the bidding as high as possible. He will not waste time by starting the bidding too low. He will also play on the opponents among his buyers and succeed in getting a high price by encouraging two business competitors to bid against each other.

Zhao Wenxuan，a film star from Taiwan，has been fond of seeing films since his childhood. He would sometimes go to the cinema for the same film four or five times. He also enjoys literature and art. Before he took the film acting as his career，he had worked in an airline in Taipei, the capital of Taiwan Province. His change of job to acting was quite by chance.
One day，he came across in the paper an advertisement for a leading actor to appear in the film named “Wedding Feast.” Full of excitement，he answered the job ad by telephoning the director of the film — Mr. Li An. It was this telephone call that had changed all his life. At last the director decided him to be the very person for the role. That he could be chosen owed much to his good command of English，natural manners and low pay for his work in the film.
The film “Wedding Feast” proved to be a hit. It won the German Golden Bear Award and entered the competition for one of the Oscar Academy Awards. Also, it was the first Taiwan film that was permitted to be shown in the U. S. Thanks to the film，Zhao Wenxuan became popular in Taiwan, Hong Kong and southeast Asia.
In 1994，Mr. Zhao acted as a leading role in the Hong Kong film，“Red Rose and White Rose”，in which many film stars like Ms Chen Chong from U. S. and Ms Ye Yuqing from the local area participated. This film was named for 10 prizes of the Taiwan Golden Horse Prize and at last it was awarded five prizes for the best play，actress and music. Zhao has regarded the film as one of his favorite films since he stepped into the acting circle.
Since 1993，Mr. Zhao has taken part in the shootings of 13 films， most of which are thought highly of.
Mr. Zhao said the that Taiwan should think to cooperate much with the mainland in the film producing industry and it would benefit each other. In recent years he often came to the mainland for film shooting. He has just completed his performance in the film “Love Affairs” directed by Mr. LiXin，a director from Shanghai Film Studio.
【小题1】Why could Zhao Wenxuan play the leading role in the movie “Wedding Feast”？

A．Because he liked to see films very much.

B．Because he was a famous actor at that time.

C．Because he could speak English very well，acted naturally and gave no thought to the pay for his work in the movie.
