分析 这就是这名在他的研究领域提出了一个新的理论的科学家．

解答 答案为A．本题考查定语从句中关系词的选择．题干中空格后面是修饰和限制名词 the scientist的定语从句，把先行词the scientist带入到定语从句，完整的定语从句是"in the scientist's research field he has put forward a new theory"；可见the scientist 在从句中充当定语，表示"…的"，故选择whose，答案是A．

点评 选择定语从句中的关系词，首先要理解各关系词的用法；然后找准先行词，将先行词带入到定语从句；最后根据先行词在定语从句中的作用判断关系词．

3．If your in-box is currently reporting unread messages in the hundreds or thousands，you might have a hard time believing the news：e-mail is on the decline．
At first blush，that might seem to be the case．The incoming generation，after all，doesn't do e-mail．Oh，they might have an account．They use it only as we would a fax machine：as a means to communicate with old-school folks like their parents or to fulfill the sign-up requirements of Web sites．They rarely check it，though．
Today's instant electronic memos-such as texting and Facebook and Twitter
messages-are more direct，more concentrated，more efficient．They go without the salutation（称呼语） and the signoff； we already know the"to"and'；from．"Many corporations are moving to messaging networks for exactly that reason：more signal，less noise and less time．This trend is further evidence that store-and-forward systems such as e-mail and voicemail are outdated．Instead of my leaving you a lengthy message that you pick up later，I can now send you an unobtrusive，easily-consumed message that you can read-and respond to-on the go．
The decline of e-mail corresponds neatly to the dawn of the mobile era．Instantaneous（及时）written messages are different．These are neatly tailored to fit in just about any time：before a movie，in a taxi，waiting for lunch．And because these notes are invariably brief，they're a natural for smart phone typing．With these formats，you also have control over who can correspond with you，which you usually don't in e-mail．And especially on Facebook，instant messaging can take
on the character of a chat room，where several people can talk at once．
Does this mean e-mail is on its way to the dustbin of digital history？Not necessarily．E-mail still has certain advantages．On the other hand，tweets and texts feel ephemeral-you read them，then they're gone，into an endless string，e-mail still feels like something you have and that you can file，search and return to later．It's easy to imagine that it will continue to feel more appropriate for formal communications：agreements，important news，longer explanations．
So，e-mail won't go away completely．Remember，we've been through a transition like this not so long ago：when e-mail was on the rise，people said that postal mail was dead．That's not how it works．Postal mail found its smaller niche，and so will e-mail．Technology rarely replaces an institution completely； it just adds new avenues．

56．What would the incoming generation like to do with their e-mail accounts？C
A．Contact close friends
B．Send long messages
C．Fill in some forms
D．Communicate with their colleagues
57．Which of the following is mainly discussed in the paragraph 3and 4？A
A．The possible reasons behind the decline of e-mail
B．The likes and dislikes of the young generation
C．The rapid development of e-communication channels
D．Evidence about the uncertain future of easily-consumed messages
58．What does the underlined word"ephemeral"in paragraph 5mean？D
A．Automatically-sending
B．Randomly-written
C．Hardly-recognized
D．Shortly-appearing
59．According to the passage，which of the following statements is true？B
A．It's too early to determine the decline of e-mail
B．E-mail has reasons to exist on its own advantage
C．E-mail，just like postal mail has come to its end
D．We should feel sorry for the decline of e-mail．
6．My oldest child，Emma，just returned to campus after a long holiday break to finish up her last period of college．These days，friends and family have begun flooding me with one question：What is she going to do after graduation？
The job market is，after all，awfully tough．Just this month the Federal Reserve Bank published a study showing that"recent graduates are increasingly working in low-paid jobs or working part-time．"The bright spot，according to the study，is for students who majored（主修） in STEM-science，technology，engineering and mathematics-areas in which recent graduates"have tended to do relatively well"．
But Emma is a student of the humanities（人文） at a small college．She's an American Studies major with a focus on the politics and culture of food．For quite a while，I think her field of study is so fashionable right now that I'm not the least bit worried she will find a good job．Yet the more I've thought about it，the more I've decided to be honest．"I'm not sure what Emma is going to do，"I now say．"But she's gotten a great education and has really found her interest．-and I know those things will serve he r well over the course of her life．"
Nowadays，more and more universities and colleges are being measured by the salaries of their recent graduates．In this climate，encouraging your kid to study the humanities，seems，at best，unwise or，at worst，unconcerned with earning a living．But a college is not a vocational（职业） school．And promoting STEM subjects should not be society's only answer to helping the next generation grow in a competitive world．
From the beginning，we never urged Emma to pick a college or a major with an eye on its expected return on money，as more and more families are doing．To Emma，what really matters will be something that we may not be able to measure for quite a long time：Emma's contribution to the world and how happy she is in it．
12．The author's friends and familyA．
A．are worried about Emma's safety        
B．have been worrying about the flood
C．are concerned about Emma's future        
D．are worried about the job market
13．What can we learn from Paragraph 2？C
A．The number of the graduates is increasing．
B．STEM graduates can be better employees．
C．STEM graduates are in relatively greater demand．
D．More and more graduates like to do a part-time job．
14．Why did Emma choose a major in the humanities？A
A．Because she is interested in it．
B．Because her mother told her to．
C．Because it is increasingly popular．
D．Because she wants further education．
15．According to the author，what matters most in choosing a major is thatD．
A．it should be among the STEM
B．it should be fashionable and interesting
C．it should allow a good job and a high salary
D．it should bring achievements and happiness．
