阅读理解一、When Mike Kelly first t out to build his own private space-ferry rvice, he figures his bread-and-butter business would be lofting high-earth orbit. Now he thinks he may have figured wrong.“People were always asking me when they could go,” says Kelly, who runs Kelly Space & Technology, “I realized the real market is in space tourism.” According to preliminary market surveys, there are 10,000 would-be space tourists willing to spend $1 million each to visit the final frontier .Space Adventures in Arlington has taken more than 130 deposits for a two-hour, $98,000 space tour tentatively t to occur by 2005. This may sound great, but there are a few hurdles. Putting a simple orbit-with no oxygen, life support or return trip necessary- already costs an astronomical $22,00/kg. And that doesn’t include the cost of insuring rich and possibly litigious pasngers. S1 The entire group of entrepreneurs trying to corner the space-tourism market have between them“just enough money to blow up one rocket.”
The U.S. space agency has plenty of money but zero interest in making space less expensive for the little guys. So the little guys are racing to do what the government has failed to do: design a reusable launch system that’s inexpensive, safe and reliable. Kelly Space’s prototype looks like a plane that has sprouted rocket engines. Rotary Rocket in California has a booster with rotors to make a helicopter-style return to Earth. The first pasnger countdowns are still years away, but bureaucrats at the Federal Aviation Administration in Washington are already informally discussing flight regulations. After all, you can’t be too prepared for a trip to that galaxy far, far away.

5. What’s the author’s tone in the last ntence of the passage? A)Objective B)Ironical. C)Approving. D)Enthusiastic.
答案与解析:
1．A 文章大意题.文章全文讨论的是太空旅游业的可行性，它的费用以及相关的问题。A为正确答案。B的意思
是在太空建造宾馆，C太空旅行规章制度，D太空旅行的费用，都不合适。
2．C bread-and-butter的意思是“主要的，谋生的”。根据上下文，当他开始创立自己的太空旅行服务社的时候，他 构想他的主要“谋生”手段就C为答案。A指出售面包奶酪的商家， B生产面包奶酪的商家，D旅行社，都不对
3．C每人去太空旅行费用是98000美元。细节题文中提到有公司收取了130多份定金，费用是两小时98000美
4. C 美国官方对于开发太空旅游业毫无兴趣。推理题.文中提到太空旅行最大的困难是资金问题，而美国官方对此毫无兴趣。C为正确答案。A意思是计划的最大困难是生命维持系统问题，B想要开发此市场的企业家们有足够的资金， D首次航程在几年内就可实行，因而都不符合原文。
5.B 作者的语气是讽刺的。综合推理题,根据上下文判断作者的语气。太空旅游的实现还很
遥远，然而有人却已开始制订起规则来了。作者的话带有讽刺意味，“为去那么遥远的地方旅行作准备再忙也不为过。”A的意思是客观的，C是赞同的，D是热衷的，都不正确。
阅读理解二、Why does cream go bad faster than butter? Some rearchers think they have the answer, and it comes down to the structure of the food, not its chemical composition—a finding that could help rid some procesd foods of chemical prervatives.
Cream and butter contain pretty much the same substances, so why cream should sour much faster has been a mystery. Both are emulsions—tiny globules (小球体) of one liquid evenly distributed throughout another. The difference lies in what’s in the globules and what’s in the surrounding liquid, says Brocklehurst, who led the investigation.
In cream, fatty globules drift about in a a of water. In butter, globules of a watery solution are locked away in a a of fat. The bacteria which make the food go bad prefer to live in the watery regions of the mixture. “This means that in cream, the bacteria are free to grow throughout the mixture,” he says.
When the situation is reverd, the bacteria are locked away in compartments (隔仓室) buried deep in the a of fat. Trapped in this way, individual colonies cannot spread and rapidly run out of nutrients (养料). They also slowly poison themlves with their waste products. “In butter, you get a lf-limiting system which stops the bacteria growing,” says Brocklehurst.
The rearchers are already working with food companies keen to e if their products can be made resistant to bacterial attack through alterations to the food’s structure. Brocklehurst believes it will be possible to make the emulsions ud in salad cream, for instance, more like that in butter. The key will be to do this while keeping the salad cream liquid and not turning it into a solid lump.
