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.
61. 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

Dreaming is a natural part of who we are. We explore our dreams and develop personal dreams. We even like to dream BIG!
For the most part our dreams and wishes focus on the end result. We see ourselves in love, married, driving a great car, on vacation, with tons of money, in a great career, etc. Dreaming about the end result is just fantasizing and wishing. Wishing relies on some magical force to make our dreams turn into reality, and we become unhappy as we’re not living(实现) our dreams.
So how can we make our dreams come true? That is a question we all often struggle with. Even though we struggle with the answer, the answer is not that clear. We make our dreams come true with the action we take.
In my opinion, if you dream about being in good health, then change your dream to see yourself working out and eating right day by day. See the beginning of the dream and let the dream build day by day with all the action that gets you to the end dream of you being in good health.
If you want riches, then change the dream. Dream of yourself going to school, developing a career, working hard and taking the steps to arrive at the destination. If you want love, love the process. Love the dating process(过程). Love yourself and the journey to find love.
Make all your dreams include the beginning, middle and end. Then when you are doing the action instead of thinking to yourself, “This is a drag. I don’t like working out,” or if you are having any negative thoughts about doing the work it takes to create your visions(梦幻), realize then that every step of the way you are living your dream. You are living your dream because you made the action and journey part of your dream.According to the writer, most of the people____.
| A．pay more attention to developing their dreams |
| B．enjoy the process of their dreams |
| C．are always ignoring the process of living their dreams |
| D．probably dream of making much more money easily |
In order to live our dreams, we must____.
| A．struggle with dreams day and night. |
| B．have great wishes and thoughts. |
| C．have magical forces every night. |
| D．take action or steps. |
If you want to keep fit,______
| A．you’d better dream a sweet dream first. |
| B．you must love the process of the journey. |
| C．you would rather begin with your diet and exercise. |
| D．you should have a good beginning first. |

How long do you want to live? How many years might be added to a life? Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.（寿命）
“I think we are knocking at the door of immortality(永生) , " said Michael Zey, a Montclair State University business professor and author of two books on the future. "I think by 2075 we will see it and that's a conservative estimate(保守的估计)."
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology(纳米技术) make it likely that humans will live in the future beyond what has been possible in the past. "There is a great push so that people can live from 120 to 180 years," he said. "Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.
However, many scientists who research into ageing are doubtful about it and say the human body is just not designed to last past about 120 years. Even with healthier lifestyles and less disease, they say the failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live. "It remains to be seen if you pass 120,you know, could you be healthy enough to have good quality of life?" said Leonard Poon, director of the University of Georgia Gerontology Centre. "At present people who could get to that point are not in good health at all."By saying "we are knocking at the door of immortality", Michael Zey means ______.
| A．they have got some ideas about living forever |
| B．they are sure to find the truth about long living |
| C．they believe that there is no limit of living |
| D．they are able to make people live past the present life span |
Donald Louria's attitude towards long living is that ______.
| A．people can live from 120 to 180 |
| B．it is possible for humans to live longer in the future |
| C．the human body is designed to last past about 120 years |
| D．it is still doubtful how long humans can live |
The underlined word "it"( in Paragraph 4)refers to______.
| A．using genes as well as nanotechnology |
| B．the idea of living beyond the present life span |
| C．a great push |
| D．the conservative estimate |

Introduction
A lot of crime is against bicycles. About 150,000 bicycles are stolen every year and most are never found. You can prevent this happening by following a few careful steps.
Basic Security
Do not leave your bicycle in out-of-the-way places. Always lock your bicycle when you leave. Secure it to lampposts(灯柱) or trees. Take off smaller parts and take them with you, for example lights and saddles(车座).
Locks
Get a good lock. There are many different types in the shop. Buy one that has been tested against attack. Ask for advice from a bike shop.
Marking
Security marking your bike can act as a deterrent to a thief. It can also help the police find your bicycle. It should be clearly written and include your postcode and your house or flat number. This will provide a simple way to identify your bicycle.
Registration

When I was about 12, I had an enemy, a girl who liked to point out my shortcomings. Week by week her list grew: I was very thin; I wasn’t a good student; I talked too much; I was too proud and so on. I tried to bear all these things as long as I could. At last, I became very angry. I ran to my father with tears in my eyes.
He listened to me quietly, then he asked, “Are the things she said true or not? Janet, didn’t you ever wonder what you are really like? Well, you now have the girl’s opinion. Go to make a list of everything she said and mark the points that are true. Pay no attention to other things she said.”
I did as he told me. To my great surprise, I discovered that about half of the things were true. some of them I couldn’t change (like being very thin), but a good number I could and suddenly I wanted to change. For the first time I got a fairly clear picture of myself.
I brought the list back to Daddy. He refused to take it, “That’s just for you,” he said. “You know better than anyone else, the truth about yourself. But you have to learn to listen, not just closing your ears in anger and feeling hurt. When something said about you is true, you’ll find it will be of help to you. Don’t shut your ears. Listen to other people’s opinions, but hear the truth and do what you know is right.”
