16.Few of us make money by losing sleep.But three graduate students at Brown University in Providence built a company around sleep deprivation (睡眠不足).
Jason Donahue,Ben Rubin and Eric Shashoua were working late nights in Brown's business and engineering schools.They began thinking about ways to sleep better.They discovered they weren't alone in burning the midnight oil.Around 20% of Americans get less than six hours of rest a night.
The friends imagined a smart alarm clock that could track how much time people spend in the most restorative (有回復(fù)作用的) stages of the sleep cycle:REM (rapid eye movement) and deep sleep.What would it cost to design such a thing?Five years of research,20 employees,$14 million and a whole lot of doubting from investors and scientists.
Their company,Zeo,based in Newton,Mass,launched its product in June,2009.The Zeo device uses a headband with tiny sensors (傳感器) that scan your brain for signs of four sleep states-REM,light,deep and waking sleep.The smart alarm clock displays a graph of your sleep pattern and wakes you as you're not in REM sleep (which is when you're least groggy).In the morning you can upload the data to the company's Web site,and so track your sleep over time.Most of the feedback comes in the form of Zeo's ZQ score showing how well you've slept.
"Zeo allows people to unlock this black box of sleep,"says Dave Dickinson,a health-care CEO.
Whether any of this actually improves sleep is up to the consumer,who will also need to make lifestyle changes like cutting out alcohol before bedtime or caffeine after 3 pm.
For now the company is selling Zeo online only.Dickinson also plans to spread it to countries such as Australia,where sleep deprivation approaches US levels.

29.Who will support Zeo?B
A.People full of imagination.
B.People suffering sleeping problems.
C.People having access to the Internet.
D.People having bad lifestyles.
30.To design the Zeo device,the three graduate studentsA.
A.spent much time and money
B.were widely supported by scientists
C.worked by themselves all the time
D.a(chǎn)ttracted many investors
31.What can we know from the passage?B
A.Zeo has a direct effect on users'lifestyles.
B.It needs more personal efforts to make Zeo function better.
C.A large quantity of Zeo devices have been sold in Australia.
D.Consumers can go to the Zeo company to purchase Zeo in person.

分析 百分之六十的美國(guó)人睡眠時(shí)間少于6小時(shí),因此有人發(fā)明了Zeo這個(gè)睡眠監(jiān)測(cè)器,它可以分析人們的睡眠,提高睡眠質(zhì)量.

解答 29.B.理解推斷題.由倒數(shù)第二段Zeo allows people to unlock this black box of sleep可知,Zeo可以幫助人們探索睡眠的奧秘,因此適合有睡眠問題的人,故選B.
30.A.理解推斷題.由第三段Five years of research,20 employees,$14 million and a whole lot of doubting from investors and scientists.可知做這項(xiàng)工作花費(fèi)了大量人力物力財(cái)力,故選A
31.B.理解推斷題.由倒數(shù)第三段Whether any of this actually improves sleep is up to the consumer,who will also need to make lifestyle changes like cutting out alcohol before bedtime or caffeine after 3 pm,是否能提高睡眠質(zhì)量取決于消費(fèi)者,他們還需要改變生活方式,比如在睡前喝掉酒精,或者下午3點(diǎn)后喝咖啡.可知還需要個(gè)人的努力,故選B.

點(diǎn)評(píng) 推理判斷題要以表面文字為前提,以具體事實(shí)為依據(jù)進(jìn)行推理,做出判斷.這種推理方式比較直接,考生只要弄清事實(shí),即可結(jié)合上下文推斷出合理的結(jié)論.

6.When I saw my 10-year-old avoiding the dirty plate in the sink or my 8-year-old feeling uncomfortable about the wet sand in her hands,I'm reminded of a time when I was unwilling to get my hands a little dirty.
    My parents owned a 500-acre farm in Montana to raise animals,such as cows,sheep,horses and so on.It was during the time of new life (a newborn lamb or a calf) that my favorite childhood memory took place.One exceptionally cold day,I was checking on the sheep with my mother when she spied a ewe (母羊) in trouble.The poor thing was trying to deliver her baby lamb and needed our help.My mother calmly held the ewe's head and instructed me to grab hold of the two protruding(突出)legs.
    I hesitated,and must have had quite a look of panic on my young face.The slimy little things were definitely not something I wanted to touch.But I worked up my courage and wrapped my fingers around them.I can still recall the feel of unexpectedly weak legs and their sharp little hooves as if it happened yesterday.
    My heart pounded in fear and excitement as I pulled with all my strength.The lamb was delivered safely,and I'd never seen anything so beautiful.
    I was no stranger to seeing farm animals being born,but to have a hand in it was something I treasured then and will treasure forever.I remember feeling excited with delight to see"my lamb"being licked clean by her mother,and I'm sure everyone got very tired of hearing me tell and retell my heroic story.Looking back,I'm so glad that I didn't refuse to get my hands dirty.If I had,the wonderful moment and the precious memory would have been lost.

24.What impressed the writer most during her childhood?C
A.Her dirty little hands.
B.Her parents'large farm.
C.Helping deliver a baby lamb.
D.Raising animals on the farm.
25.How did the author feel when she was asked to help a ewe deliver her baby?B
A.Some sympathy.
B.Rather frightened.
C.Quite astonished.
D.Highly delighted.
26.What point does the author try to make in the last paragraph?D
A.It is not unusual to see a new life coming into the world.
B.It is not easy to make up and tell a heroic story in daily life.
C.Memories formed during childhood are worth valuing all life long.
D.You need to get your hands dirty to experience something precious.
27.What could be the best title for the passage?A
A.A Valuable Life Lesson           
B.A Tidy and Clean Child
C.A Ewe Delivering her Baby        
D.A Beautiful Newborn Lamb.

7.Recently some American scientists have given a useful piece of advice to people in industrialized nations.They say people should eat more of the same kind of food eaten by humans living more than 10,000 years ago.(36)F
The scientists say that the human life has changed greatly.Our bodies have not been able to deal with these changes in lifestyle and this had led to new kinds of sicknesses.(37)ASo they are called"diseases of civilization".Many cancers and diseases of the blood system are examples of such diseases.
Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed v ery little alcohol or tobacco,probably none.(38)EHowever,a change in food is one of the main differences between life in ancient times and that of today.
Stone Age people hunted wild animals for their meat,which had much less fat than domestic ones.They ate a lot of fresh wild vegetables and fruits.They did not have milk or any other dairy products,and they made very little use of grains.(39)DWe eat six times more salt than our ancestors.We eat more sugar.We eat twice as much fat but only one third as much protein and much less vitamin C.
(40)BBut scientists say that we would be much healthier if we eat much the same way as our ancestors did,cutting the amount of fatty,salty and sweet food.

A.These new sicknesses were not known in ancient times.
B.People today probably do not want to live the way people thousands of years ago did.
C.Ancient people also lived in large groups.
D.But today,we eat a lot of these.
E.Ancient people also got a great deal of physical exercise.
F.In that case,they would live much healthier.
G.People today probably live the same life as people thousands of years ago.

4.When I first started university,I remembered hearing about bone marrow(骨髓)donation during Freshman's Week.Some students volunteers from a group called Marrow tried to convince me to attend an event so I could learn more about it.The word"bone"immediately made me think that donating would be a painful procedure,so I refused.Back then,there was no way I could have known three years later,I would be one of the many people that desperately needs a bone marrow donor to save their lives.
I am currently waiting to be matched with a donor and if I am lucky enough to find a good match,it will be this lovely stranger that saves my life.I received my cancer diagnosis in June.It is only at that time that I realized how ignorant I had been about the bone marrow donation process.
The process of donating stem cells is actually very simple.In 90% of cases,donors are asked to donate their blood stem cells,the other 10% will give their bone marrow.Lots of donors say that both these things are virtually pain free,and nothing to be scared about.Being a bone marrow donor should be something to be proud of,as every donor has an opportunity to save someone's life!
At the moment I know that the doctors are busy searching for a match,I simply live every day in the hope that there will be a donor right for me.If I have an opportunity for life,I won't waste it.
When I was a first year at university,I made the mistake of walking away from becoming a stem cell donor.Please don't make the same mistake that I did.There are so many people out there,including myself,that need your help; and by undergoing a simple,pain-free procedure,you could have the chance to proudly say that you saved someone's life.

4.Why did the author refuse to learn more about bone marrow donation before?B
A.Because she could get nothing from it.
B.Because she thought that donating would be painful.
C.Because she had known nothing about it.
D.Because she was in poor health.
5.What can we learn from the underlined sentence in paragraph 1?C
A.The author was concerned about others.
B.The author was confident about the bone marrow donation.
C.The author needs the bone marrow donation now.
D.The author donates her bone marrow to save others.
6.The author needs the bone marrow because she gotA
A.cancer         
B.headache        
C.flu       
D.high blood pressure
7.The author told us her story toD.

B.explain the cause of her cancer.
C.recall her painful past.
D.encourage people to be a bone marrow donor.
