18.If you don't know what it means,______ the dictionary.( 。
A.look upB.refer toC.point toD.look out

分析 你不知道這是什么意思,參考查閱一下字典.

解答 答案B.
look up查找,仰望,向上看;refer to參考;涉及;指的是;適用于;point to指向;表明;look out注意;朝外看;照料;當(dāng)心.look up與refer to都有"參考""查詢"的意思,但搭配不同.(1)look up的賓語多為word,information等,不可以是book,dictionary,sb.等.(2)refer to意思比較廣泛,它既可作"查詢""查找"講,又可作"談到""提及"講.其賓語多為book,dictionary,sb.等.根據(jù)句子所要表達的意思和look up與refer to的區(qū)別可知答案選B.

點評 本題考查動詞短語的辨析.英語中有的詞組沒有捷徑,只有平時加強記憶,要注意區(qū)別,記憶的時候不能忽視,這是常見的命題方式.平時要加強記憶,做題時,別忘了要結(jié)合上下文句意判斷.
look up與refer to都有"參考""查詢"的意思,但搭配不同.(1)look up的賓語多為word,information等,不可以是book,dictionary,sb.等.如:
You may look up the word in the dictionary if you don't know its meaning.
如果你不知道這個單詞的意思,你可以查一下詞典.
(2)refer to意思比較廣泛,它既可作"查詢""查找"講,又可作"談到""提及"講.其賓語多為book,dictionary,sb.等.如:
She didn't even refer to the notes when she made the speech.
作演講的時候,她甚至不看筆記.
When I meet new words I don't know,I often refer to the dictionary.
當(dāng)我遇到不認識的新單詞時,我經(jīng)常查詞典.
I don't know what"it"refers to.
我不知道"it"指什么.

9.Conventional wisdom is a major barrier to innovation(創(chuàng)新) that threatens the survival of companies everywhere.It's based on the assumption that old ideas will always work,so they shouldn't be challenged.While this may be a valid(有效的) assumption in situations that don't change,it's unlikely to hold true in a changing situation.In today's rapid changing global environment,old methods often don't work,and stubbornly using them can lead to major problems.
Most people seem to agree with conventional wisdom because it gives one a false sense of security.If everyone else believes it,then it must be true.Individuals who use conventional wisdom are certain that they are right,and being right is good.They want to continue using old ideas rather than take risks with changes that might not work.In 1977,Ken Olsen,co-founder and CEO of Digital Equipment Corporation (DEC),stated"There is no reason for any individual to have a computer in his home."Despite being a dominant leader in the computer industry,DEC no longer exists.
People seem to forget that since innovation is a change,there can be no innovation without change.Unfortunately,conventional wisdom prevents leaders,followers and companies from changing and therefore innovating.If companies don't innovate,but their competitors do,the future is likely to be problematic.Breaking from conventional wisdom has led to many of the most innovative companies and products in history across many industries,so it has a powerful effect on business success.
Ted Turner (founder of CNN) knew little,if anything,about the news business,but he knew it was inconvenient to watch news only at the dinner hour,as was common before CNN.Turner's solution was to create a cable channel dedicated to news 24 hours a day.The news establishment reflected conventional wisdom at the time,and predicted his idea would fail because no one wanted to watch the news all day.However,it doesn't take a rocket scientist to understand that viewers don't have to watch the news all day for the CNN to work.Viewers just have to watch when they want to get information.Due to conventional thinking,the critics failed to recognize the opportunity that was clear to Ted.They assumed that only what was familiar to them could work in the future.
Conventional wisdom prevents creativity,flexibility and risk-taking,so unconventional leaders enthusiastically break from it.To survive,thrive and maintain competitive advantage,companies must be flexible when reacting to change.
28.DEC has disappeared probably becauseC.
A.the consumers didn't like its products
B.the leaders lacked the sense of security
C.the CEO stuck to the conventional ideas
D.the employees took many risks with changes
29.The founding of CNN is used as an example to proveB.
A.missing opportunities could lead to failure
B.changing could contribute to business success
C.watching news at the dinner hour is convenient
D.conventional wisdom influences business success
30.What does the underlined part probably mean?D
A.Rocket scientists can ensure the CNN works properly.
B.Most of the viewers don't like to watch the news at work.
C.It's necessary to understand when people watch the news.
D.It's easy to know people needn't watch the news all the time.
31.The passage is mainly written to tell us thatC.
A.old methods are changing with time
B.opportunities lead to business success
C.conventional wisdom limits innovation
D.successful companies need wise leaders.

8.The bed should be reserved as a place for sleep,but people tend to read an iPad a lot in bed before they go to sleep.
Charles Czeisler,a professor at Harvard Medical School,and his colleagues got a small group of people for an experiment.For five days in a row,the people read either a paper book or an iPad for four hours before sleep.Their sleep patterns were monitored all night.Before and after each trial period,the people took hourly blood tests to paint a day-long picture of just how much melatonin (褪黑激素) was in their blood at any given time.
When subjects read on the iPad as compared to the paper books,they reported feeling less sleepy at night and less active the following morning.People also took longer to fall asleep on the iPad nights,and the blood tests showed that their melatonin secretion (分泌) was delayed by an hour and a half.
The researchers conclude in today's journal article that given the rise of e-readers and the increasingly widespread use of e-things among children and adolescents,more research into the long-term consequences of these devices on health and safety is urgently needed.Czeisler and colleagues go on,in the research paper,to note:"Reading an iPad in bed may increase cancer risk."
However,software has been developed that can reduce some of the blue light from the screens of phones and computers according to time of day,and there are also glasses that are made to filter (過濾) short wavelengths.While they seem like a logical solution for the nighttime tech users,it needs more research.
28.In Charles Czeislers experiment,all the subjects were asked toB.
A.sit in a row and receive the strict tests             
B.have their sleep patterns observed all night
C.read a paper book and an iPad at the same time      
D.have their blood tested per hour during the trial
29.The third paragraph tells us the iPad readers were likely toC.
A.feel less sleepy and tired in the day    
B.fall asleep more easily after reading
C.become less energetic the next morning 
D.have a lot more melatonin secretion
30.The special software recently developed canC.
A.remove the blue light from your devices completely
B.help prevent eyes being harmed by short wavelength
C.weaken the harm done by doing nighttime e-reading
D.be used in all the e-things widely and safely
31.Which of the following can be the best title for the text?A
A.No e-reading in bed before sleep
B.New software for night e-readers
C.Wrong behaviors before bedtime 
D.No games on iPad in bed.
