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.
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
The underlined word “sidestepped” in Para. 1 most probably means ________.
A. improved B. reduced C. avoided D. solved
Raymond Li’s friends found his idea for the aquatic jet pack was ________.
A. exciting B. crazy C. realistic D. creative
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.
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, b B. c, e, a, b, d C. e, c, d, b, a D. e, a, c, d, b

Tt was a village in India. The people were poor . However, they were not unhappy. After all , their forefathers had lived in the same way for centuries.
Then one day, some visitors from the city arrived . They told the villagers there were some people elsewhere who liked to eat frog’s legs. However, they did not have enough frogs of their own, and so they wanted to buy frogs from other places.
This seemed like money for nothing . There were millions of frogs in the fields around, and they were no use to the villagers. All they had to do was catch them .

The right to pursue happiness is issued to us all with our birth, but no one seems quite sure what it is.
A holy man in India may think that happiness is in himself. It is in needing nothing from outside himself. If wanting nothing, he lacks nothing. We westerners, however, are taught that the more we have from outside ourselves, the happier we will be, and then we are made to want. We are even told it is our duty to want. Advertising, one of our major industries, exists not to satisfy these desires but to create them---and to create them faster than any man’s money in his pocket can satisfy them. Here, obviously someone is trying to buy the dream of happiness and spending millions upon millions every year in the attempt. Clearly the happiness-market is not running out of customers.
I doubt the holy man’s idea of happiness, and I doubt the dreams of the happiness-market, too. Whatever happiness may be, I believe, it is neither in having nothing nor in having more, but in changing --- in changing the world and mankind into pure states.
To change is to make efforts to deal with difficulties. As Yeats, a great Irish poet once put it, happiness we get for a lifetime depends on how high we choose our difficulties.
It is easy to understand. We even demand difficulty for the fun in our games. We demand it because without difficulty there can be no game. And a game is a way of making something hard for the fun of it. The rules of the game are man-made difficulties. When the player ruins the fun, he always does so by refusing to play by the roles. It is easier to win at chess if you are free, at your pleasure, to cast away all the rules, but the fun is in winning within the rules.
The same is true to happiness. The buyers and sellers at the happiness-market seem to have lost their sense of the pleasure of difficulty. Heaven knows what they are playing, but it seems a dull game. And the Indian holy man seems dull to us, I suppose, because he seems to be refusing to play anything at all.
The western weakness may be in the dreams that happiness can be bought while eastern weakness may be in the idea that there is such a thing as perfect happiness in man himself. Both of them forget a basic fact: no difficulty, no happiness.
1.Who shares the same idea of happiness with the author?
A. The Indian holy man B. The great Irish poet Yeats
C. Advertisers D. The buyers and sellers at the happiness-market
2.What does “happiness-market” mean in the second paragraph?
A. It means a place in which people can buy things happily
B. It means a market which lacks happy customers
C. It means a pure state for the world and mankind
D. It means a market where people try to buy happiness with money.
3.According to the passage, which of the following is Right?
A. The Indian holy man is much happier than westerner.
B. The westerners understand happiness better than the Indian holy man.
C. There is no fun without playing by the rules
D. Both the eastern weakness and western weakness are the same.

One of the most famous buildings
in the United States is Carnegie Hall, the home of classical and popular music
concerts in New York. Carnegie Hall is known not just for its beauty and
history, but also for its amazing sound. It has been said that the hall itself
is an instrument. It takes the music and makes it larger than life.
Carnegie Hall is named after Andrew Carnegie, who paid for its construction. He was a wealthy man who also gave a lot of money to schools and public libraries. Construction on Carnegie Hall began in 1890 and the official opening night was on May 5, 1891.
The hall was owned by the Carnegie family until 1924 when it was sold to Robert E. Simon. The building became very old and in 1960, the new owner made plans to destroy it and build an office block. Isaac Stem led a group of people who fought to save Carnegie Hall and finally, the city of New York bought it for $5 million. It was then fixed up between 1983 and 1995.
In 1986, people realized that Carnegie Hall had never kept proper records of its history. Advertisements and stories in newspapers about how Carnegie Hall needed help to recover its history led people to send in old concert programmes and information from all over the world. Over 12,000 concert programmes were received and with these it was possible to make a proper record of Carnegie Hall’s concert history.
Carnegie Hall is actually made up of several different halls, but the Main Hall, now called the Isaac Stern Hall, is the most famous. Most of the greatest performers of classical music since the time the hall was built have performed in the Main Hall, and its reception areas are decorated with signed photographs of these musicians. The hall itself can hold an audience of 2,804 in five levels of seating. Visitors to the top level have to climb up 105 steps to get there!
Because the best and most famous musicians of all time have played at Carnegie Hall, it is the dream of most musicians who want to be great to play there. This has led to a very old joke which is now part of Carnegie Hall’s history. Question: “How do I get to Carnegie Hall?” Answer: “Practise, practise, practise.”
1.What do music lovers expect in Carnegie Hall?

e. Construction on Carnegie Hall began in 1890.
A. a; c; b; d; e; B. e; d; c; a; b C. e; b; a; d; c D. a; e; c; d; b
3.How long did it take Carnegie Hall to be fixed up?

4. How did Carnegie Hall recover its concert history?
