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 |
A.improved | B.reduced | C.avoided | D.solved |
A.exciting | B.crazy | C.realistic | D.creative |
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. |
A.c, e, a, d, b | B.c, e, a, b, d | C.e, c, d, b, a | D.e, a, c, d, b |

Loch Ness, the largest freshwater lake in the British Isles, is twenty four miles long and, at one point, one mile wide. It has an average depth of four hundred and fifty feet and at times drops close to a thousand. It is cold and murky (混沌的), with dangerous currents. In short, it is the perfect place to hide a monster from even the sharpest eyes of science.
The Loch Ness Monster, also called Nessie, is supposedly living in this area. The earliest recorded sighting of the Loch Ness Monster was in the biography of Life of St. Columba by Adamnan in the year AD 565. The monster apparently attacked a man who was swimming in the River Ness.
The monster didn’t make headlines again until August 27, 1930, when 3 fishermen reported seeing a creature with 20 feet long approaching their boat, throwing water in the air. In 1933, after a new road was built along the edge of the Loch, the number of reports rose suddenly. Early in 1934, Author Grant, a young student, was out on his motorcycle one evening when he almost ran into the monster as it crossed the road. Grant’s description of the thing – small head, long thin neck and tail with a big body, seemed to match the appearance of the plesiosaur (蛇颈龙), an aquatic (水生的) type of dinosaur that has been extinct (已灭绝的) for 65 million years.
The Loch Ness Investigation Bureau was formed in 1962 to act as a research organization for information about the creature. Even now, efforts have continued to find the monster. A great deal of information was discovered about the Loch, but there isn’t any yet to produce any specific evidence of a monster.
Skeptics (怀疑论者) argue that the water in the Loch is too cold for a plesiosaur to live in. They also argue that an air-breathing animal, like a whale or seal, would spend much more time on the surface than the creature seems to, and would be spotted more often.
Some scientists have wondered if the sightings might be caused by an underwater wave which is known to sometimes occur in deep, long, and cold lakes, like Loch Ness. Such a wave might push debris (废弃物) to the surface that might look like a strange animal.
However, none of these is identified.
【小题1】According to the skeptics, which of the following is TRUE?
A.It is impossible for a monster to live in cold water. |
B.The Loch Ness Monster often stays under the water. |
C.The Loch Ness Monster is an air-breathing animal. |
D.There is no so-called monster in Loch Ness. |
A.b, e, c, a, d | B.a, b, e, d, c |
C.b, d, a, c, e | D.d, c, e, b, a |
A.The natural scenery of Loch Ness. |
B.The Nessie. |
C.Skeptics’ opinions on Loch Ness Monster. |
D.The Loch Ness Investigation Bureau’s research results. |
