   Flying like a bird has been the dream of humans since ancient times. Last week a group of modern birdmen put their courage on their wings and __45___ gravity (地球引力) in Hangzhou, Zhejiang Province.

   “Yes, you can buy a ticket and fly to another city. But running with your own wings and feeling your feet ready to _46___ is totally different,” Dong Fang said in an excited voice. He is one of 41 students from Hangzhou No. 14 Middle School to test their home-made aircrafts in the playground.

   __47___ by the International Bognor Birdman Competition in the UK. Ni Wangyue, a teacher in the high school is holding a similar event. The Bognor Birdman competition started in 1971 in the England costal city Bognor. People run off the end of a pier (码头) with their own aircraft in a(n) ___48___ to “fly” the furthest distance.

   “From the very beginning, I didn't expect my students to create a real plane or break any records. I told them the __49___ is more for seeing how far your imagination can stretch, ” said Ni. He was surprised to see his students create 10 different aircrafts with all kinds of material __ 50____ in the past month. Many students said that they learnt much more in the process of creating their plane than in ordinary classes.

   “We’d rather call ourselves dreamers __51___ pilots because no matter whether our wings really take off from the ground, our dream really flies,” said Dong Fang.

   Jing Yuchen and his team named their plane “Weiming E”, which __52__an unknown goose. The 17-year-old boy deeply believes their goose of steel pipe and sailcloth(帆布) will honour its name by successfully taking off.

  “Our work is much more imaginative than others. With several colourful balloons on its back and a pair of light plastic wings it is _53___ the most eye-catching work, if not the best,” said Yu Liang, another student.

   “__54___most of those home-made aircrafts cannot really take the boys flying, the boy’s braveness and creativity in this project will encourage every one of them to fly high in the future,”Ni said.

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 waterB.unbearable noiseC.unsafe fuelsD.too much weight
【小题2】The underlined word “sidestepped” in Para. 1 most probably means ________.
A.improvedB.reducedC.avoidedD.solved
【小题3】 Raymond Li’s friends found his idea for the aquatic jet pack was ________.
A.excitingB.crazyC.realisticD.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.
