The dream of flying like Buzz Lightyear never dies. For years, space-age invento

题型:不详难度:来源:
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.
The pump is started.
A.c, e, a, d, bB.c, e, a, b, dC.e, c, d, b, aD.e, a, c, d, b

Years ago, when I started looking for my first job, wise advisers advised," Barbara, be enthusiastic (热情的) ! Enthusiasm will take you further than any amount of experience. "How right they were!
"Nothing great was ever achieved without enthusiasm." wrote Ralph Waldo Emerson. It isthe paste that helps you hang on there, then the going gets tough. It is the inner voice that whispers, "I can do it!" When others shout, "No, you can"t!" It took years and years for the early work of Barbara McClintock, a geneticist who won the 1983 Nobel Prize in medicine, to be generally accepted, yet she didn"t stop working on her experiments. Work was such a deep pleasure for her that she never thought of stopping.
We are all born with wide-eyed, enthusiastic wonder and it is this childlike wonder that gives enthusiastic people such youthful air, whatever their age. At 90, Cellist Pablo Casals would start his day by playing Bach. As the music flowed through his fingers, his stooped shoulders would straighten and joy would reappear in his eyes. An author and poet Samuel Ulman once wrote," Years wrinkle the skin, but to give up enthusiasm wrinkles the soul. "
Enthusiastic people also love what they do, regardless of money or title or power. Patricia Mellrath, retired director of the Missouri Repertory Theater in Kansas City, was once asked where she got her enthusiasm. She replied, "My father, a lawyer, long ago told me, "I never made a dime until I stopped working for money." "
If we can"t do what we love as a full-time career, we can as a hobby. Elizabeth Layton of Wellsville Kan, was 68 before she began to draw. This activity ended periods of depression that had troubled her for at least 30 years, and the quality of her work led one critic to say, "I am tempted to call Layton a genius. "
We need to turn the tears into sweat as we go after "what-can-be". We need to live each moment whole-heartedly, with all our senses--finding pleasure in the sweet smell of a back-yard garden, the simple picture of a six-year-old, the beauty of a rainbow.
72. Which of the following would be the best title for the test?
A. Enthusiastic people will never get old.
B. Enthusiasm can make you succeed and enjoy life.
C. Enthusiasm is more important than experience.
D. Enthusiasm can give people more success and fame.
73. Which of the following can best explain the underlined sentence in the second paragraph?
A. Enthusiasm can give you courage and strength in difficult times.
B. If you don"t have enthusiasm, you can achieve nothing.
C. Enthusiastic people never consider money and fame.
D. Enthusiastic people can gain great fame and honour.
74. The author mentions Cellist Pablo Casals in the third paragraph to show that _______.
A. music can arouse people’s enthusiasm
B. enthusiasm can give people needed inspiration to succeed
C. enthusiasm can make people feel young
D. enthusiasm can keep people healthy
75. How many examples are given in the passage to show the importance of enthusiasm?
A. Three.           B. Two.              C. Four.             D. Five.

My daddy doesn’t know how to express love at all. It is my mum that makes everyone happy and calm in our family; while daddy only works day and night, never looking us in the face. But mum makes a wrongdoing list of us for daddy scolding us. She’s a spy!
  Once, I stole a candy. Daddy asked me to put it back and told the shopkeeper that I would like to carry loads for her. Well, mum told him I was just a child.
  I broke my leg on the playground. It’s still mum that held me tightly in her warm arms. Daddy drove us right to the emergency room. He was asked to move the car away for that vacant was for ambulance. Daddy got angry, “what do you think of it? A touring car?”
  On my birthday party, it was, again, my mum that took over the cake for me. My dad? He was busy blowing balloons and setting the table and doing the housework.
  While looking over our album, friends always ask, “What does your father look like?” God knows. He photos others all the time. So there are many and many photos of my mum and me, pretty and lovely photos.
  And I still remembered the day when dad taught me riding. I asked him not to let his hands away, but he did the opposite. And I certainly fell onto the ground. I got angry and decided to get on the bike and rode. But he smiled again.
  Mum wrote every letter to me while I was in college. He, except checks, did write a letter, but extremely short, just a few words, saying, “Without your playing on the lawn, my son, my lawn grows prettier than before.”
  Every time I phoned, it seemed he wanted to talk, but he would say, “I will get your mum.”
  On the day of my wedding, mum cried as if we would never meet again, while dad went out with a nasal sound.
  From very young, I heard him saying, “Where have you been?” “When do you go home?” “Did you get oil for your car?” “No, I don’t agree.” Dad really knows nothing about showing love. Unless... 
Maybe he showed while I didn’t notice, is it?

A. Because he parked his car at a wrong place.
B. Because the parking space of the ambulance was very crowded.

A. was not patient when he taught the writer riding
B. might want to see his child fall off the bike
