解答答案A．
must必须，非得；could可能，可以；would愿意；should除了有"应该"的意思外，还有"万一、竟然"之意，should 表示"可能"时，肯定句中与if 连用，表示"可能性很小"．放在句首，可省略if．根据句子所表达的意思可知should的意思在本题中意思是"万一"，故答案选A．

点评本题考查情态动词的用法．在掌握情态动词的基本含义的时候，还要掌握一些情态动词的特殊含义．如：must表示与说话人愿望相反及不耐烦，含义为偏要、硬要．would+动词原形表示过去的习惯或某种倾向．shall用于第二人称和第三人称表示建议，允诺，命令，威胁等．
should表示惊讶时，意思是"竟然"，should还有"万一、竟然"之意，与if连用，如If you should see her，call me．（万一你见着她，打电话给我）．

   In Silicon Valley，it's never too early to become an entrepreneur．Just ask 13-year-old David Moore．The eighth-grader has launched a company last October to develop low-cost machines to print Braille （布莱叶盲文）．David built a Braille printer with a Lego Mindstorms EV3kit as a school science fair project last year after he asked his parents a simple question：How do blind people read？"Google it，"they told him．David then did some online research and was shocked to learn that Braille printers cost at least 2，000dollars-too expensive for most blind readers．
"I just thought that price should not be there．I know that there is a simpler way to do this，"said David，who demonstrated how his printer works at the kitchen table where he spent many late nights building it．David wants to improve the"Braigo"-a name that combines Braille and Lego-and develop a desktop Braille printer that costs around 350dollars and weighs just a few pounds，compared with current models that can weigh more than 20pounds．"My end goal would probably be having most of the blind people…using my Braille printer，"said David，who lives in the Silicon Valley suburb of Santa Clara，just minutes away from Intel headquarters．
After the Braigo won numerous awards and enthusiastic support from the blind community，David started Braigo Labs last summer with an initial 35，000dollars investment from his dad．"We as parents started to get involved more，thinking that he's on to something and this new way process has to continue，"said his father，Matthew Moore，an engineer who works for Intel．
Intel officials were so impressed with David's printer that in November they invested an undisclosed sum in his start-up．They believe he's the youngest entrepreneur to receive venture capital money invested in exchange for a financial stake in the company．"He's solving a real problem，and he wants to go off and challenge an existing industry，"said Edward Ross，director of Inventor Platforms at Intel．Now the company is using the money to hire professional engineers and advisers to help design and build Braille printers based on David's ideas．It aims to have a prototype （样机） ready for blind organizations to test this summer and have a Braigo printer on the market later this year．

66．Which of the followings is Not the description of Braigo？C
A．The name"Braigo"comes from Braille and Lego．
B．The blind are in favor of the new type of printer．
C．It costs less money and weighs just a few pounds．

Printers．

69．What can we learn from Paragraph 4？A

Street dances are dance styles that evolved (演变) outside of dance studios in any available open space. They are often improvisational (即兴的) and social in nature，encouraging interaction and contact with audiences and the other dancers. These dances generally evolve out of urban and suburban spaces and are a part of the native culture of that geographical area. Some examples of street dances include B-boying, or breakdancing, which originated in New York City, and Melbourne Shuffle which originated in Melbourne, Australia.

Street dances are dances that evolve between people in a social environment，although it cannot be always determined as to how they actually do evolve between people. In theory, as one person comes up with a move that looks good to another person, that other person tries to copy that move. Similar to the game of Chinese Whispers, the effect is that the other person cannot absolutely perform that move the same way as the other person, thus leading to the dancer creating their own style or entirely new moves.

There is a small difference between entirely freestyle dance and an absolute street dance. While freestyle dance is random and a personal dance invented by a single person (even if ifs based on someone else’s dance style), a full street dance is a collection of the various similar dance moves and styles collected into one practice and regarded as the same dance. For example, when B-boying evolved out of early hip-hop culture, people came up with their own moves, and other people improved them. Street dances constantly evolve for as long as they are now and then practiced and regarded as the same dance. All the moves danced to breaks in hip-hop culture were regarded as B-boying.

Sometimes it is possible to trace back street dance styles that were mostly pioneered by specific persons. One example is Locking, which is often regarded as being started by Don Campbell, who was a 1970s pioneer of American street dance. Most of the time it is impossible to owe street dances to specific people; since the dances evolve outside of professional dance environments, and there is no social or legal record. Street dance pioneers also rarely have professional degrees in dance, thus distinguishing street dance from other modern dance forms.
