18.The scientist expected that enough data could be______ to him______ he went to improve his theory.(  )
A.reachable; howeverB.accessible; whichever
C.available; whereverD.sensitive; whatever

分析 這位科學(xué)家希望無論他想在那個方面提高他的研究都能夠得到足夠的數(shù)據(jù).

解答 答案是C.本題考查形容詞詞義辨析和從句引導(dǎo)詞的選擇.reachable可到達(dá)的; accessible可到達(dá)的,可接近的;available可得到的,有空的; sensitive敏感的;根據(jù)句意,這位科學(xué)家希望數(shù)據(jù)是"可得到的",因此答案是C.第二空是連接副詞wherever引導(dǎo)的讓步狀語從句,表示"無論哪里,無論哪個方面",本題中指的是"無論在哪個方面",做狀語.whichever和whatever都是連接代詞,在句中不能做狀語;however表達(dá)的是"然而,無論如何",不符合句意.

點評 形容詞辨析的關(guān)鍵在于積累詞匯和一些相關(guān)的固定搭配,在此基礎(chǔ)上結(jié)合語境,做出合理的判斷.
從句引導(dǎo)詞的選擇首先要根據(jù)句意和結(jié)構(gòu)分析從句類型,然后根據(jù)各引導(dǎo)詞在不同從句中的用法進(jìn)行判斷.

6.The herds of bulls and horses depicted running along the walls of the Lascaux caves in France are among the most magnificent examples of prehistoric art ever discovered.
Courage is a quality we cherish.Yet only lately has it been studied systematically to try to define what it is and is not,where it comes from and why we love it so much."Courage helps to define the excellent person,"write George Kateb,a political theorist at Princeton University."One of the worst criticism in the world is to be called a coward,a quite timid person."
For many people,courage is most readily displayed in battle; for example,the brave soldier running into the line of fire to rescue the injured.
Yet George Kateb says that if courage finds its highest expression in war,then the trait (特性) becomes immoral,ennobling killing by insisting that only in battle can people discover the depths of their nobility.Thus,it makes killing a noble thing.
Stanley J Rachman of the University of British Columbia studies paratroopers (傘兵) preparing for their first jump.The work revealed three different groups:the fearless who jumped without hesitation; the timid whose fear kept them from jumping; and finally,the ones who reacted physiologically like the timid but acted like the fearless leaper,and jumped.
Rachman considered the final group courageous,defining courage as"a behavioral approach in spite of the experience of fear".Thus,courage becomes the property of anyone who does something that he or she fears.
In interviewing 320children aged from 8to 13,Peter Muris of Erasmus University,Rotterdam,of the Netherlands and his colleagues found that children also consider courage as the conquering of one's fears; and more than 70% claimed they had performed brave acts,including stealing money from one's mother's purse.
Joel Berger,a biologist with the Wildlife Conservation Society in Montana,US,also distinguishes between animals that behave bravely due to a lack of awareness and experience,and those that are aware of a danger but proceed anyway.
He recalled the time he and his colleagues had cornered a young bison (野牛) to take blood samples.At that time,an adult male bison was standing guard,refusing to let the scientists approach."He knew that he could be attacked by us,"said Berger."I'd call this a courageous,even heroic act."

78.What does George Kateb think of courage?Courage helps define the excellent person.
79.Why did Rachman think that the third group were courageous?Because they conquered their fears and jumped
80.Peter Muris found that most children demonstrated their courage.by performing bravely and blindly.
81.The writer uses the example of an adult bison to.illustrate/show/prove that animals are also courageous
(Note:Answer the questions or complete the statements in NO MORE THAN EIGHT WORDS)

13.It is surprising that eating three meals a day--breakfast,lunch and dinner--has been a custom only since 1890.Before this time,they only had two meals a day--breakfast and dinner.
In the 16th century,breakfast was only to break one's fast (隨便吃一點).But 200years later it had became a large meal,not just for family,but for numbers guests as well.It was a social event.It began at 10a.m.a(chǎn)nd lasted until 1p.m.Then breakfast began to be less popular.It became,instead,a lighter meal and was taken at a much earlier hour.By 1850it had been pushed back to 8a.m.a(chǎn)nd became a family meal.
Dinner,however,went to the other way.In the 16th century it was eaten at 11p.m.Years later,it had moved to the early afternoon,then to 5p.m.By 1850dinner time had reached 7p.m.Lunch is a recent idea.It first appeared as a snack to fill the gap(間隙)between breakfast and dinner.

10.Every day we are exposed to images,videos,music and news.In this age of visual and aural hyper-stimulation,the medium of radio is making a great comeback.
"We're at the beginning of a golden age of audio,"said US-based podcaster Alex Blumberg in an article in The Sydney Morning Herald.In the last month alone,15 percent of US adults listened to a radio podcast (播客).These statistics,released by Edison Research,show the successful evolution of traditional radio broadcasts to the present day's digital podcast format.The term"podcast"was invented in 2004,but the trend only started gaining mainstream popularity in recent years.With the sharp increase in consumer demand for smartphones and tablets,podcast sales have jumped.
The appeal of the podcast partly lies in its multiplatform delivery and on-demand capabilities (功能).You can listen during those extra minutes of the day when you're walking to the shops,waiting in a queue or riding the subway.Similar to television shows,podcasts are generally free to download and most offer new content every week.
Donna Jackson,22,Sydney University media graduate,listens to podcasts two or three times a week,via iTurns."I listen while I'm wandering around the house doing something else.It makes completing a boring task much more enjoyable…And it's an easy way of keeping in touch with what's going on in the rest of the world,"she said,"I mainly listen to BBC podcasts,but recently I've also been listening to This American Life and Serial.They have a special skill to really draw you in."
Unlike television and music,the audio format has the potential to create a deep impression on readers.Blumberg says this owes to the podcast's ability"to create close relationship and emotional connection."Sydney University undergraduate Hazel Proust,majoring in social work and arts,agrees."When you're listening,it feels as if the voice of the podcast's storyteller is talking directly to you.It's comforting,"said Proust.
It seems the age-old tradition of verbal storytelling is very much alive and well.

67.From the first two paragraphs,we can learn thatC.
A.traditional broadcast has come back
B.Americans love listening to the radio
C.podcasts have become very popular today
D.smartphones sell well because of podcasts
68.The writer mentions Donna Jackson mainly toB.
A.tell how young people relax themselves
B.explain why young people like podcasts
C.introduce what programs podcasts are presenting
D.show how popular podcasts are presenting
69.Paragraph 5is mainly aboutB.
A.the influence of radios
B.the advantage of podcasts
C.readers'impression on radios
D.people's reaction to the medium
70.What is probably the best title of the passage?A
A.Return of Radio
B.Opinions of Podcast
C.Features of Radio
D.Technology of Podcast.

7.Do you want to love what you do for a living?Follow your passion (激情).This piece of advice provides the foundation for modern thinking on career satisfaction.But this can be a problem.
I've spent the past several years researching and writing about the different strategies (策略) we use to seek happiness in our work.It became clear early in the process that the suggestion to"follow your passion"had some mistakes,for it lacks scientific evidence.However,it doesn't mean you should abandon the goal of feeling passionate about your work.The reality emphasizes that things are quite complicated.
Passion is earned.Different people are looking for different things in their work,but generally,people with satisfying careers enjoy some combination of the following features:autonomy,respect,competence,creativity,and a sense of impact.In other words,if you want to feel passionate about your livelihood,don't seek the perfect job,but seek to get more of these features in the job you already have.
Passion is elusive.Many people develop the rare and valuable skills leading to passion,but still end up unhappy in their work.The problem is that the features leading you to love your work are more likely to be useful to you than your organization.As you become increasingly"valuable",for example,your boss might push you toward traditional promotions that come with more pay and more responsibility,as this is what is most useful to your company.However,you might find more passion by applying your value to gain autonomy in your schedule or project selection.
Passion is dangerous.I've watched too many of my peers fall into anxiety and constant job-hopping due to the"follow your passion"advice.The issue is expectations.If you believe we all have a pre-existing passion,and that matching it to a job will lead to instant workplace happiness,reality will always pale in comparison.Work is hard.Not every day is fun.If you're seeking a dream job,you'll end up disappointed,again and again.Don't set out to discover passion.Instead,set out to develop it.This path might be longer and more complicated than what most cheerful career guides might support,but it's a path much more likely to lead you somewhere worth going.

47.People satisfied with their careers areB.
A.a(chǎn)utonomous and passionate
B.creative and competent
C.respectable and sensitive
D.creative and passionate
48.What does the underlined word"elusive"in the 4th paragraph most probably mean?D
A.Easy to develop.
B.Easy to keep.
C.Hard to develop.
D.Hard to keep.
49.The underlined sentence in paragraph 5 probably means thatC.
A.it is not easy to match our passion with our jobs
B.we shouldn't think everyone has a pre-existing passion
C.high expectations of passion in jobs bring disappointment
D.workplace happiness does not require a pre-existing passion
50.What is the author's advice on achieving career satisfaction?A
A.Developing passion for what one is doing.
B.Matching the pre-existing passion to one's work.
C.Figuring out early what one will do in the future.
D.Discovering skills that lead to interesting careers.
