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.
小題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
小題2:The underlined word “sidestepped” in Para. 1 most probably means ________.
A.improvedB.reducedC.a(chǎn)voidedD.solved
小題3: Raymond Li’s friends found his idea for the aquatic jet pack was ________.
A.excitingB.crazyC.realisticD.creative
小題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.
小題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

Like most people, I was brought up to look upon life as a getting. It was not until in my later thirties that I made this important discovery: giving-away makes life so much more exciting. One discovery I made about giving away is that it is almost impossible to give away anything in this world without getting something back, though the return often comes in an unexpected form. One Sunday morning the local post office delivered a letter to my home, though it was addressed to me at my office. I wrote the postmaster a note of appreciation. More than a year later I needed a post office box for4 a new business I was starting. I was told at the window that there were boxes left, and that my name would have to go on a long waiting list. As I was about to leave, the postmaster appeared in the doorway. He had overheard our conversation.“Wasn’t it you that wrote us a letter a year ago about delivering a special delivery to your home?”I said it was.“Well, you certainly are going to have a box in this post office if you have to make one for you. You don’t know what a letter like that means to us. We usually get nothing but complains.”
46.  At first the author looked upon life as a process of getting. He formed this view of life because
.
A.other people were selfish B.he thought it exciting to get from others

49.  The postmaster promised        .
A.to make a new post-office box for the author
B.to let the author have a post-office box
C.to include the author’s name on the list
D.to deliver the author’s mail to his home
50.  The postmaster interfered because      .
A.he overheard this conversation
B.he had received a lot of complaints for lack of post-office box

Both warm-blooded and cold-blooded desert animals have ways to escape the desert heat. Warm-blooded desert animals, such as rats and mice, rest during the day, often staying in cool underground burrows. At night they search for food. Animals that are out during the day, such as cold-blooded lizards and snakes, are active only for short periods. As their body temperature rises, these reptiles move into the shade in order to cool down. In the early evening, when the sun grows weaker, the reptiles become more active and begin their search for food again.
Getting enough water to survive is a major problem for all desert animals. Some desert animals, such as the kangaroo rat and the related jerboa, get water only from the food that they eat. Because these animals eat mainly dry seeds, they must survive on a tiny amount of water.
Most deserts have only a small number of frogs and toads because these animals must be near water to survive. Yet even these creatures have adapted to desert conditions. When small amounts of water collect in temporary streams, the desert-living frogs and toads become active. After a rainfall, they lay their eggs. The eggs grow into tadpoles in a few days and into adults in just four weeks. When the puddles dry up, the adult frogs or toads dig into the ground. Their metabolism(新陳代謝) slows, and they stay beneath the ground until the next rain, which may be as good as a year away. Until then, their bodily activities continue at a reduced rate.
The camel---often called the ship of the desert---is one of the most successful desert animals. Camels can go for long periods without water, but eventually they must drink. When water becomes available to them after a long drought, they may drink 95 liters of water or more. When water is not available, what helps camels survive the desert heat is the fat stored in their humps. A camel’s hump contains about 12 kilograms of fat. Fat is rich in hydrogen. As the fat is digested, hydrogen from the fat combines with oxygen in the air that the camel breathes. The result is H2O, or water. Each kilogram of fat that a camel digests produces about a liter of water.
71. Desert animals are usually more active at night because ______.
A. it is cooler at night           B.it is easier to find water
C.they like the dark            D. they are less likely to be attacked at night
72. Which of the following desert animals can get water only from the food?
A. The camel.       B. The kangaroo rat.     C. The frog.      D. The toad
73. Which of the following is TRUE according to the passage?
A. All the desert animals rest during the day.
B. All the desert animals don’t rest during the day.
C. Cold-blooded desert animals don’t rest during the day.
D. None of the cold-blooded desert animals go out during the day.
74. The title for this passage could probably be ________.
A. Hot Deserts                        B. Desert Animals
C. How Desert Animals Get Water         D. Ways To Escape the Desert Heat
75. The underlined word “burrows” in the first paragraph can be replaced by _________.
A. holes     B. caves     C. rooms      D. openings

The choice to adopt and hold gratefulness is the one that is different from those who suffer misfortune and those who enjoy a full life.
My mother died when I was 24. It was a very difficult time in my life - everything seemed to fall apart. I lost my job, and then my utilities were turned off. I had to take cold showers for six months. A neighbor who knew about my situation came to my house and made me an offer. I took care of her children as a job, and I no longer went hungry. I was surprised that someone would trust me-a young woman-with her children. And it was with the very confidence that before long I began taking care of other people's children, too. I have since moved 300 miles from Boise, Idaho. For more than 23 years I have made every effort to reach out to all the kind-hearted people who helped me when I was down and out. Without their trust, I don't know what I would have done. I am very involved in my community and volunteer at the local food bank, and I help out whenever I can. I'd like to owe what I am to whoever has offered me generosity.
If you are grateful for what you already have, the world will work together to give you more to be grateful for. Otherwise, the world will give you more to complain about.
Moreover, the true master learns to be grateful, in advance, for the things that are desired, because, being grateful in advance for some attainment or accomplishment does two very important things: one-it tricks your subconscious(潛意識)into believing that the goal is certain and two…it convinces other people, with whom you must interact to achieve your desires, that you know what you are about, that you are a winner, not a whiner(哀訴者).
65. The underlined "utilities" refers to such things as ______ in the passage.
A. gas and electricity  supplies                      B. water and gas supplies
C. shower equipment and water supply          D. heating and TV signals
66. The writer was grateful mainly for ______.
A. his neighbor's donation                B. his community       
C. having got the job                    D. others' trust
67. The writer's personal story in the second paragraph tells us that ______.
A. to be grateful will get you nowhere but away from home
B. we need to be grateful to be helpful and useful
C. a grateful person is most likely to be successful
D. the fragrance (芳香) stays in the hand that gives the rose
68. The best title for the passage would be ________.
A. A Thank-You Note to Trusting Neighbor   B. You Are a Winner, Not a Whiner
C. Gratefulness Brings a Great Fullness to Life D. Be Grateful to Life in Advance

   Probably many of you know the idiom “an eye for an eye and a tooth for a tooth”. But do you believe a tooth for an eye? That’s something a little bit different.
This strange exchange is neither a form of retribution(報應(yīng)) nor an unexpected gift from the Tooth Fairy --- it’s actually a very generous gift from a young Irishman, Robert McNichol, 23, to his formerly blind father, 57-year-old Bob McNichol.
In 2005, Bob McNichol’s sight was destroyed in an accident when his eyes were doused(濺在……上面)with liquid aluminum(鋁). Doctors predicted that he would never be able to see again.
But McNichol never liked to take no for an answer: when he heard about a unique operation called Osteo-Odonto-Keratoprosthesis, he knew he had to give it a shot, even though the success rate was a mere 65 percent.
In the technique, the eye socket(眼窩) is rebuilt and implanted(植入) with a human tooth and part of the jawbone, to provide support for an artificial cornea(角膜). Luckily for McNichol, Robert was willing to sacrifice one of his teeth to help his father regain his sight.
The technique isn’t simple: McNichol’s first stint on the operating table lasted ten hours, with a five hour follow-up session at a later date. But thanks to his son’s gift, he’s already seeing astonishing results.
“Now I have enough sight for me to get around and I can watch television. I have come out from complete darkness.” he told his friends.
小題1:Bob McNichol lost his sight ____ .
A.a(chǎn)fter he had an operation on his eyes
B.because of an accident
C.because he met with a serious traffic accident
D.when he was 57 years old
小題2:The underlined phrase “give it a shot” (in Paragraph 4) probably means “____”.
A.give it a tryB.make a remark C.fire a gunD.kick the ball
小題3:The tooth Bobert donated to his father is used to ____ .
A.make the eye socket look prettierB.cause his jawbone to function well
C.help his father take in more foodD.support the implanted artificial cornea
小題4:What would be the best title for the passage?
A.Father and sonB.A unique eye operation
C.A man defeating darknessD.Blind man sees with aid of son’s tooth

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?
56. From the first and second paragraphs, we can infer that____.
A. it was the daddy that was in charge of his children’s education
B. the writer’s parents loved their children; at the same time, they were strict with them
C. the children were all afraid of their father so they had to be cute
D. the writer’s mom was like a spy who reported what the children did to the father
57. Why did the father get angry when he sent the writer to the hospital?
A. Because he parked his car at a wrong place.
B. Because the parking space of the ambulance was very crowded.
C. Because the writer’s injury made the father quite upset.
D. Because the person paid little attention to his son’s serious injury.
58. According to Paragraph Six, we know the father ____.
A. was not patient when he taught the writer riding
B. might want to see his child fall off the bike
C. used a wrong way of teaching his child riding
D. might want his son to learn riding through independent practice
59. Which of the following is not true according to the passage?
A. The dad posted checks to the writer while he was in college.
B. The dad had no single photo of his own in the album.
C. The dad scolded the writer for having damaged the lawn.

Growing up, I had a scar on my face — a perfect arrow in the center of my cheek, pointing at my left eye. I 36 it when I was three, long before I knew that scars were a 37 thing, especially for a girl. I only knew that my scar brought me 38 and tenderness and candy. As I got older, I began to take 39in my scar, in part to stop people laughing at me, but mainly as a reaction to the thought that I should feel uncomfortable. It’s true. I was 40 the first couple of times someone pointed at my 41 and asked, “What’s that?” or called me “Scarface.” But the more I heard how 42 my scar was, the more I found myself liking it.
When I turned fifteen, my parents — 43 the advice of a doctor — decided it was time to 44 on what was now a thick, shiny red scar.
“But I don’t mind the scar, really,” I told my father as he 45 that I would have the operation during my summer vacation. And my friends, along with my boyfriend at the time, 46 as I did, that my scar was 47 and almost pretty in its own way. After so many years, it was a 48 of me. But my father said it was a deformity (畸形). I don’t know what 49 more that day: hearing my father call my scar a deformity, 50 realizing that it didn’t 51 to him how I felt about it.
I did have the operation that summer.
In my late twenties, I took a long look at my scar, something I hadn’t done in years. 52, it could be seen in the right light, but no one 53 me about it anymore. As I leaned uneasily toward the mirror, I felt a sudden 54.
