According to the US government, wind farms off the Pacific coast could produce 900 gig watts of electricity every year. Unfortunately, the water there is far too deep for even the tallest windmills (see picture) to touch bottom. An experiment under way off the coast of Norway, however, could help put them anywhere.
The project, called Hywind, is the world’s first large-scale deepwater wind turbine(渦輪發(fā)電機(jī)). Although it uses a fairly standard 152-ton,2. 3-megawatt turbine, Hywind represents totally new technology. The turbine will be fixed 213 feet above the water on a floating spar(see picture),a technology Hywind's creator, the Norwegian company StatoilHydro, has developed recently. The steel spar, which is filled with stones and goes 328 feet below the sea surface, will be tied to the ocean floor by three cable(纜索); these will keep the spar stable and prevent the turbine from moving up and down in the waves. Hywind's stability(穩(wěn)定性)in the cold and rough sea would prove that even the deepest corners of the ocean are suitable for wind power. If all goes according to plan, the turbine will start producing electricity six miles off the coast of southwestern Norway as early as September.
To produce electricity on a large scale, a commercial wind farm will have to use bigger turbines than Hywind does, but it's difficult enough to balance such a large turbine so high on a floating spar in the middle of the ocean. To make that turbine heavier, the whole spar's to design a new kind of wind turbine, one whose gearbox(變速箱) sits at sea level rather than behind the blades (see picture )
Hywind is a test run, but the benefits for perfecting floating wind-farm technology could be extremely large. Out at sea, the wind is often stronger and steadier than close to shore, where all existing offshore windmills are planted. Deep-sea farms are invisible from land, which helps overcome the windmill-as-eyesore objection. If the technology catches on, it will open up vast areas of the planet’s surface to one of the best low-carbon power sources available.
63. The Hywind project uses totally new technology to ensure the stability of ________.
A. the cables which tie the spar to the ocean floor
B. the spar which is floating in deep-sea water
C. the blades driven by strong and steady sea wind
D. the stones filled in the spar below the sea surface
64. To balance a bigger turbine high on a flatting spar, a new type of turbine is to be designed with its gearbox sitting ________.
A. on the sea floor B. on the spar top
C. at sea level D. behind the blades
65. Wide applications of deepwater wind power technology can ________.
A. solve the technical problems of deepwater windmills
B. make financial profits by producing more turbines
C. settle the arguments about environmental problems
D. explore low-carbon power resources available at sea

Shay asked, "Do you think they'll let me play?" Shay's father knew that most of the boys would not want someone like Shay on their team, but the father also understood that if his son, mentally and physically disabled, were allowed to play, it would give him a much-needed sense of belonging and some confidence.
Shay's father approached one of the boys on the field and asked if Shay could play, not expecting much. The boy looked around and said, "We're losing by six runs (分) and the game is in the eighth inning (局). I guess he can be on our team and we'll try to put him in to bat in the final inning.
Shay struggled over to the team's bench and put on a team shirt with a broad smile and his father had a small tear in his eye and warmth in heart. The boys saw the father's joy at his son being accepted.
In the bottom of the eighth inning, Shay's team scored a few runs but was still behind by three. In the top of the final inning, Shay put on a glove and played in the field. Even though no hits came his way, he was obviously joyful just to be in the game and on the field. In the bottom of the final inning, Shay's team scored again. Now, Shay was scheduled to be next at bat. Would they let Shay bat and give away their chance to win the game?
Surprisingly, Shay was given the bat. Everyone knew that a hit was almost impossible. The first pitch (投) came and Shay missed. The pitcher again took a few steps forward to throw the ball softly towards Shay. As the pitch came in, Shay swung at the ball and hit a slow ground ball right back to the pitcher.
The pitcher could have easily thrown the ball to the first baseman and Shay would have been out and that would have been the end of the game. Instead, the pitcher threw the ball right over the head of the first baseman, beyond the reach of all teammates, The audience and the players from both teams started screaming, "Shay, run to first! 'Never in his life had Shay ever run that far but made it to first base, wide-eyed and shocked.(www.nmet168.com)
Everyone shouted, 'Run to second!' Catching his breath, Shay awkwardly ran towards second. By the time Shay rounded towards second base, the smallest guy on their team, who had a chance to be the hero for his team for the first time, could have thrown the ball to the second baseman, but he understood the pitcher's intentions and he too intentionally threw the ball high and far over the third baseman's head.
All were screaming,"Shay,Shay,Shay,all the way Shay.' Shay reached third base when one opposing player ran to help him and shouted, "Shay, run to third." As Shay rounded third, all were on their feet, crying, "Shay, run home!" Shay ran to home, stepped on the home base and was cheered as the hero who won the game for his team.
That day, the boys from both teams helped bring a piece of true love and humanity into this world. Shay didn't make it to another summer and died that winter, having never forgotten being the hero and making his father so happy and coming home and seeing his mother tearfully hug her little hero of the day!
66. Not expecting much, Shay's father still asked the boy if Shay could play, mainly because the father ________.
A. noticed some of the boys on the field were heisting
B. guessed his presence would affect the boy's decision
C. learned some of the boys on the field knew Shay well
D. understood Shay did need a feeling of being accepted
67. In the bottom of the final inning Shay was given the bat because the boys ________.
A. believed they were sure to win the game
B. would like to help Shay enjoy the game
C. found Shay was so eager to be a winner
D. fell forced to give Shay another chance
68. The smallest boy threw the ball high and far over the third baseman's head, probably because that boy ________.
A. was obviously aware of the pitcher's purpose
B. looked forward to winning the game for his team
C. failed to throw the ball to the second baseman
D. saw that Shay already reached second base
69. Which of the following has nothing to do with Shay’s becoming the hero for his team?
A. The pitcher did not throw the ball to the first baseman.
B. The audience and the players from both teams cheered for him.
C. The opposing players failed to stop his running to home.
D. One of the opposing players ran to help him.(www.yygrammar.com)
70. What do you think is the theme of the story?
A. True human nature could be realized in the way we treat each other.
B. Everyone has his own strength even if mentally or physically disabled.
C. Everyone can develop his team spirit in sports and please his parents.
D. The results of the game should not be the only concern of the players.
