10．---I don't know why Denise started crying when I mentioned the wedding．
---It ______ what you said about her brother．Or，perhaps she is just nervous．（　　）

	A．	should have been		B．	couldn't have been
	C．	could have been		D．	must have been

分析 -我不知道为什么我提到婚礼时，丹尼斯开始哭泣．
-可能是你说的那些关于她兄弟的话．要不然，也许她只是紧张了．

解答答案：C 题干中perhaps表明是不肯定的推测；对过去情况的推测用情态动词加完成时态．could表示可能，must表示一定，故选C．

点评情态动词的用法是英语中常考的语言点．通常考查的方式有虚拟和推测，本题考查的是情态动词的推测用法．学习时要注意积累．

Microsoft just finished a three-month experiment operating an underwater data center．A server rack（服务器支架） with the power of about 300PCs was placed into a water-tight（防水） steel container and lowered into the ocean off the coast of central California．
The unusual experiment was launched because current data centers are unpleasantly inefficient．They're built where energy and land are cheap （not close to where people actually live）．And they waste so much energy cooling their massive computers．The ocean can solve those problems．The cold ocean floor sufficiently cools the computing components inside the pod．And since most people live near the ocean，placing data centers under water could potentially increase the speed at which customers could access the information stored in Microsoft's cloud．
The experiment was so successful that Microsoft operated the underwater data center for 75days longer than it had planned to．The next step is to get a larger pod，with about four times the computing power，under the ocean for testing．Unlike the first experiment，the next pod will also be equipped with turbines，which will transform the ocean's currents into electricity．It's not clear when，if ever，underwater data centers will become a possible product．"Our first experiment was like dipping our pinkie toe in the water，and now we're going for the big toe，"said Lee，corporate vice president of Microsoft Research．
Microsoft is still analyzing the environmental impacts of the study．Data centers are both hot and loud，which could have damaging effects on ocean life．Microsoft found that the noise its underwater data center produced was drowned out by nearby shrimp and crabs．The data centers are also built from recyclable materials，and Microsoft believes that the total carbon footprint of underwater data centers will be"dramatically lower"than current land-based centers．
Given the growth in the cloud，industry analysts believe that most of the world's data centers have yet to be built．But building a data center takes at least two years-an  eternity in the fast-developing tech industry．As a result，Microsoft builds its data centers with the future in mind，installing far more computing power and space than it currently needs．
Lee believes that going under water can shift the building of data centers from construction projects to manufacturing jobs．"What if we could mass-produce these pods on an assembly line？"he thought．"We could deliver a data center，from conception to operation，in 90days．That's dramatically different than what's happening today．"

62．What is the advantage of an underwater data center？D
A．It can be lowered to the ocean floor easily．
B．It can cool computing components automatically．
C．It can be built close to the place where people live．
D．It can make information easily accessible to people．
63．We can infer that the underwater data centersB．
A．cause little harm to the ocean life  B．are more environmentally friendly
C．change the course of ocean currents  D．are easy to build in large quantities
64．The underlined word"eternity"in Paragraph 5means"A"．
A．an extremely long time  B．an extended period
C．a seemingly short time  D．a fruitful period
65．The passage tries to inform readers thatC．
A．an experiment was made in operating a data center
B．Microsoft will mass-produce pods on an assemble line
C．Microsoft succeeded in putting a data center underwater
D．underwater data centers are more efficient than land-based ones．

19．Kong Zi，also called Confucius （551-479 B．C），and Socrates （469-399 B．C） lived only a hundred years apart，and during their lifetimes there was no contact between China and Greece，but it is interesting to look at how the world that each of these great philosophers came from shaped their ideas，and how these ideas in turn，shaped their societies．
Neither philosopher lived in times of peace，though there were more wars in Greece than in China．The Chinese states were very large and feudal，while the Greek city-states were small and urban．The urban environment in which Socrates lived allowed him to be more radical than Confucius．Unlike Confucius，Socrates was not asked by rules how to govern effectively．Thus，Socrates was able to be more idealistic，focusing on issues like freedom，and knowledge for its own sake．Confucius，on the other hand，advised those in government service，and many of his students went out to government service．
Confucius suggested the Golden Rule as a principle for the conduct of life："Do not do to others what you would not want others to do to you．"He assumed that all men were equal at birth，though some had more potential than others，and that it was knowledge that set men apart．Socrates focused on the individual，and thought that the greatest purpose of man was to seek wisdom．He believed that the superior class should rule the inferior（下层的）classes．
For Socrates，the family was of no importance，and the community of little concern．For Confucius，however，the family was the centre of the society，with family relations considered much more important than political relations．
Both men are respected much more today than they were in their lifetimes．
