21、int?24.How does the woman respond to this second request?25.What is the source of the mans third complaint?Passage One When e-mail first came into general use about fifteen years ago,there was a lot of talk about the imminent arrival of the paperless office.However,it seems that e-mail has yet to re

22、volutionise office communication.According to communications analyst Richard Metcalf,some offices have actually seen an increase in paper as a result of e-mail.Information in the form of e-mail messages now floods our computer screens.These messages can be sent so quickly that memos tend to be distr

23、ibuted in the hundreds.For those secretaries whose bosses ask them to print out all their e-mails and leave them in their in-trays,this means using up a great deal of paper every month,Metcalf says.Metcalf has found that because some e-mails get lost in cyberspace,PAs are increasingly likely to be a

24、sked by clients and colleagues to send all important documents both by e-mail and by fax or snail mailthrough the post.This highlights a further potential problem with e-mail in todays officesit is taking up time rather than saving it.With e-mail,communication is much easier,but there is also more r

25、oom for misunderstandings,says psychologist Dr David Lewis.Generally,much less care is taken with e-mails than with letters or faxes and the sender will probably print the document and reread it before putting it in an envelope or sending it by fax.Questions 26 to 28 are based on the passage you hav

26、e just heard.26.Why has the promise of the paperless office not come true in many offices?27.What can be inferred from Richard Metcalf s findings?28.How does David Lewis feel about e-mail messages?Passage Two Today most of astronomers accept the notion that groups of stars that make up the universe

27、are all moving farther and farther away from each other,but until very recently this idea of an expanding universe was not a theory most European scholars believed in since ancient times and up to 17th century most of these scholars thought the size of the universe had remained unchanged since the m

28、oment of its creation or perhaps forever,with all the stars more or less in place in relation to each other.But that idea was challenged in the late 17th century by Izic Newtons idea of gravity as a force of attraction,which contradict the idea of a university that is static,unchanging.If gravity ca

29、uses all the stars out there in space to attract each other as Newton said,then they could remain motionless.Sooner or later all the stars will fall in absorb each other.Well,scientist then propose a new model,taking Newtons theory into account,they didnt want to abandon the idea of motionless stars

30、,but for this model to work,so the stars wont fall in each other,they had to modify Newtons law of gravity,so they theorize that for distance as large as those between stars,the gravitation repels rather than attracts.As you might guess,there are other contradictions.But this is prettily resolved in

31、 the past centuries by currently accepted theory,which says the universe is continuously expanding.Questions 29 to 31 are based on the passage you have just heard.29.what does the passage mainly discuss?30.What did most European scholars believe before 17th century about the size of the universe?31.

32、What did some scientists try to explain by suggesting that stars repel each other?Passage Three For most of us,the purpose of the holidays is to bring peace,love,and goodwill towards all.Yet,for many,the holiday season often means stress,fatigue,pressure,disappointment and loneliness.These feelings,

33、often known as the holiday blues,may be even more prevalent this year,due to the emotional disorder of the past few months,not to mention the unsteady economy.Experts say even the more ritual tasks of shopping,decorating,late-night parties,cooking,planning and family reunions can be holiday stressor

34、s.In addition,the psychological phenomenon known as seasonal affective disorder,or SAD,may bring a specific type of depression related to winters shorter days and longer nights.Certainly just because its the holidays doesnt mean people are going to be happy.says Dr.Doug Jacobs of Harvard University.

35、And this will be a particularly hard holiday for some who are dealing with a lost job,debt,or even a lost loved one.And with family reunions becoming less frequent events over the years,there is now the added pressure of getting just one chance to get it all right.The disappointment and sense of ali

36、enation that often results from family gatherings,he adds,is actually a realization that the fantasy is not met.Still,say experts,the blues should be addressed.The most essential step,says Stutesman,is for the individual to acknowledge their feelings.Denial will only increase the stress theyre feeli

37、ng.Stutesman recommends people do things that are normally comforting in order to get a handle on the holiday stress.If theyre feeling a little blue,they should try to do things personally satisfying for them.Maybe this is exercise,cooking,reading a book,or massage.Stutesman also advises that someti

38、mes avoidance is actually not such a bad idea.In some situations,fulfilling social obligations may be self-destructive when the best thing may be to just stay home.The healthy choice has to do with taking care of oneself.Questions 32 to 35 are based on the passage you have just heard.32.What is the

39、reason for“holiday blues to be even more prevalent?33.Why does Dr.Doug Jacob say“Certainly just because its the holidays doesnt mean people are going to be happy?34.According to Stutesman,what is the essential step to address the blues?35.According to the passage,what should a person do if he wants

40、to recover from“holiday blues?Section C Internet technology experts have shown that searches conducted using Web search engines can be put into three categories,namely informational,navigational,and transactional.Jim Jansen,(36)assistant professor in Penn States College of Information Sciences and T

41、echnology,worked with IST undergraduate Danielle Booth and Amanda Spink,Queensland University of Technology,on the project that led the categorisation of Web searches.The researchers say that informational searching(37)involves looking for a specific fact or topic,while navigational searching seeks

42、to(38)locate a specific Web site.Transactional searching looks for information related to buying a particular product or service,they add.The researchers have(39)revealed that they conducted this research using actual searching data,with the aim of real-time(40)classification.During the study,more t

43、han 1.5 million queries from hundreds of thousands of search engines users were analysed.The studys results show that about 80 per cent of queries are informational,and about 10 per cent each are for navigational and transactional(41)purposes.Jansen and his colleagues achieved those results by selec

44、ting(42)random samples of records,and analysing query(43)length,the order of the query in the session and the search results.(44)Their work has even enabled them to develop an calculation that classified the searches with a 74-per cent accuracy rate.“Other results have classified comparatively much

45、smaller sets of queries,usually manually.This research aimed to classify queries automatically,Jansen said.“(45)Our findings have broad implications for search engines and e-commerce if they can classify the user intent of queries in real time.This is why we wanted a computational undemanding calculation.It proves the 80/20 rule that 80 per cent of the cases can be achieved with these clear-cut methods,Jansen added.(46)He now is continuing this research using a more complex calculation that will hopefully yield a 90-per cent accuracy rate.
