9.Around the world,a lot of fresh water basins lie underground.These groundwater basins are like banks.Now,changes in climate and human water usage are emptying those groundwater basins,a new study finds.And it's happening at a worrying rate.Of Earth's 37largest groundwater basins,21of them lose more water each year than they gain.The conclusion is troubling.That's according to the study coauthor Sasha Richey.About 2billion people drink water from underground water basins.Crops also need such water to grow.
People get groundwater by drilling into groundwater basins called aquifers(储水层).Aquifers are refilled when water goes down through the soil.Scientists can know about groundwater through wells.Water levels drop as an aquifer becomes empty.This method fails to provide a global picture of changes in water levels,though.
Richey and her colleagues used data collected by the GRACE mission instead.Theses win satellites measure small changes in Earth's gravity.Changes in the density(密度) of Earth's surface cause those small changes in gravity.The emptying and refilling of groundwater basins is one way that the density of Earth's surface changes.The GRACE satellites pass over these buried basins regularly.As they do,the satellites"weigh"the mass of the water stored inside.
The researchers examined gravity changes over Earth's largest aquifers in the past ten years.Eight of the studied aquifers lost great volumes of water over that decade.The researchers considered these aquifers as"overstressed".That means almost no water naturally went in to supersede the water being taken out.The regions of greatest concern were in the Middle East,northern Africa and northwestern India and Pakistan.
The most dried-up aquifers were in areas near large cities,in heavily agricultural areas or in dry areas.All three characteristics probably led to the extreme stress affecting the basins below central California,Richey says.California has both people and farms.It's also in a sever drought.As a result,the state's pumping of groundwater recently has greatly increased.
32.What can we learn from the finding of the new study?D
A.There are 37large groundwater basins in the world in all
B.Most of the world's groundwater basins are empty
C.Men are cautious about using underground water
D.Climate change is shrinking underground water
33.To learn about the current situation of groundwater basins,Richey and her colleaguesC.
A.collected data of aquifers around the world
B.used two satellites to study the effect of climate change
C.referred to the data about changes in Earth's gravity
D.observed the buried groundwater basins frequently
34.What does the underlined word"supersede"in Paragraph 4mean?A
A.Replace           
B.Increase       
C.Improve      
D.Support
35.We can learn from the last paragraph that in California a lot of peopleC.
A.go to central California for water
B.don't know the importance of groundwater
C.depend on groundwater for their daily activities
D.are aware they're harming groundwater basins.

分析 本文是一篇科教类阅读,主要介绍了地下水的减少及科学家对地下储水层的一些研究.

解答 32-35.DCAC
32题答案:D考查细节推理,根据第一段的Now,changes in climate and human water usage are emptying those groundwater basins,a new study finds.一项新的研究发现气候的改变和人类对水的使用使这些地下盆地变空.可知本题答案为D选项"气候变化使地下水缩减".
33题答案:C考查细节推理,根据文章第三段的Richey and her colleagues used data collected by the GRACE mission instead.Theses win satellites measure small changes in Earth's gravity.Richey和她的同事使用GRACE任务所收集的数据,这些获胜卫星测量地球重力的微弱变化.可知本题答案为C选项.
34题答案:A考查细节推理,结合前面一句The researchers considered these aquifers as"overstressed"."研究者认为这些储水层压力过大"可知后面一句话的意思是"那意味着没有水能自然进入从而代替被取出的水",故本题答案为A选项.
35题答案:C考查细节推理,根据最后一句As a result,the state's pumping of groundwater recently has greatly increased.因此美国加州地下水的抽取近期大幅增加.可知本题答案为C选项"日常生活依靠地下水".

20.An Oil for Life
olive
Maria Alcala of Madrid speaks for many Mediterranean people when she says that"a meal without olive oil would be a bore."No one knows when the Mediterranean civilizations fell in love with olives.That occurred before recorded history.However,there is evidence that the cultivation (种植) of olive trees began in countries around the Mediterranean Sea in approximately 4000B.C.,and 2000years after that people in the eastern Mediterranean area began to produce oil from olives.The Mediterranean still accounts for 99percent of all world olive oil production.
From ancient times until today,the basic process of producing the oil is the same.First,whole olives are pressed hard into pieces.Then,the liquid is separated from the solids.After that,the valuable oil is separated from the water.
Many olive growers make their ancient traditions continue and still harvest the olives by hand."We harvest in the traditional way,"says Don Celso,an olive farmer from Tuscany,Italy."It would be less expensive to do it with machines,but it's more a social thing.Twenty people come to help with the harvest,and we pay them in oil."
Olive oil has had a variety of uses through its long history.In ancient times,olive oil was used as money and as medicine.It was even used during war-heated up and dropped down on attackers.It is still used in religious ceremonies.It is great for protecting the freshness of fish and cheese.There are even olive oil lamp and olive oil soaps.
One important study shows that Mediterranean people have the lowest rate of heart disease among Western nations.This is partly associated with their frequent use of olive oil.Other studies show that food cooked in olive oil is healthier,and that eating olive oil twice a day reduces women's risk of getting breast cancer.The world is beginning to understand its benefits,and olive oil is no longer an unusual sight at dinner tables outside the Mediterranean area.The olive oil producing countries now sell large amounts of olive oil to countries in Europe,Asia,Africa,and North and South America.
Olive oil improves the lives of people everywhere.Its benefits,recently confirmed by science,were already understood in ancient times.Mediterranean people are happy to share their secret with the world.

48.Which step occurs first in olive oil production?D
A.Drying the olives under the sun.
B.Separating the oil from the water.
C.Separating the liquid from the solids.
D.Pressing the whole olives into pieces.
49.Which use of olive oil is NOT mentioned in the passage?A
A.Paint.
B.Medicine.
C.Money.
D.Soap.
50.Why does the author include information about several studies of olive oil?C
A.To give reasons why olive oil is similar to medicine.
B.To show how the biology of Mediterranean people is special.
C.To explain the growing interest in olive oil around the world.
D.To prove that olive oil is more important for women than for men.
51.What is the passage mainly about?B
A.Discussing olive oil production outside the Mediterranean area.
B.Explaining the history,production,benefits,and use of olive oil.
C.Showing why olive oil is produced around the Mediterranean Sea.
D.Comparing Mediterranean olive oil with that produced in other places.
17.Speed-reading is a necessary skill in the Internet age.We skim over articles,e-mails and We Chat to try to grasp key words and the essential meaning of a certain text.Surrounded with information from our electronic devices,it would be impossible to cope if we read word by word,line by line.But a new trend calls on people to unplug and enjoy reading slowly,listing benefits beyond the intelligent stimulation.
A recent story from The Wall Street Journal reported on a book club in Wellington,New Zealand,where members meet in a cafe and turn off their smart phones.They sink into comfortable chairs and read in silence for an hour.Unlike traditional book clubs,the point of the slow reading club isn't exchanging ideas about a certain book,but to get away from electronic devices and read in a quiet,relaxed environment.According to the Journal,the Wellington book club is just one example of a movement started by book lovers who miss the old-fashioned way of reading before the Internet and smart phones.
Slow readers,such as The Atlantic's Maura Kelly,say a regular reading habit sharpens the mind,improves concentration,reduces stress levels and deepens the ability to sympathize(共鸣,同感).Another study published last year in Science shwed that reading novels helps people understand other's mental states and beliefs,a fundamental skill in building relationships.Yet technology has made us less attentive readers.Screens have changed our reading patterns from the staight and information left-to-right sequence to a wild skimming and skipping pattern as we hunt for important words and information.Reading text punctuated(加标点符号)with links leads to weaker comprehension than reading plain text.The Internet may hve made us stupider,says Patrick Kingsley from The Guardian.Because of the Internet,he says,we have become very good at collecting a wide range of interesting news,but we are also gradually forgetting how to sit back,reflect,and relate all these facts to each other.
Slow reading means a return to an uninterrupted,straight pattern,in a quiet environment free of distractions.Aim for 30minutes a day,advises Kelly from The Atlantic."You can squeeze in that half hour pretty easily if only during your free moments,you pick up a meaningful work of literature,"Kelly said."Reach for your e-reader,if you like.Kindles make books like War and Peace less heavy,not less substantive,and also ensure you'll never lose your place."
24.The book club in Wellington mentioned in Paragraph 2showsA.
A.the new trend of slow reading   
B.the decline of electronic devices
C.the importance of exchanging ideas   
D.the increasing number of club readers
25.According to Patrick Kingsley,people are stupider partly because ofD.
A.a non-stop reading pattern         
B.the straight,left-to-right screen
C.wide range of interesting news     
D.the lack of reflection
26.According to the passage,slow readingA.
A.contributes to understanding among people
B.promotes the current technology advances
C.provides people with a quiet environment
D.cures the memory loss of elderly people
27.What's the best title for the passage?B
A.Benefit of Reading Clubs          
B.Return of Slow Reading
C.Reading of the Internet Age         
D.Influence of Speed Reading.
4.Knuckle-popping(指关节砰砰响)
Do you slurp(咕噜)soup?Do you pop bubble gum?If you do,your habits won't help you win friends-but they're fun.But how about knuckle-popping?Not you does this hobby give people around you the"willies([俚]神经紧张),"but cracking knuckles can lead to monster knuckles(异乎寻常的响声),and maybe-to arthritis (关节炎).
At least,most people think knuckle-popping is bad.Well,there's no doubt that the people who have to listen to knuckles being snapped(啪地一声折断)can't stand the sound.But how bad is it for the knuckle-popper?
A doctor has looked into this indoor sport.He says it's not harmful.Dr.Robert L.Swezey found that his son was cracking his knuckles.And the kid's grandmother thought it was terrible.So Dr.Swezey went to a home for the aged.He studied the knuckles of old people there.Only one out of fifteen old people who said they cracked their knuckles all their lives had something wrong with their finger joints.Also,five out of twelve women who never cracked their knuckles had trouble with their joints.So if you want to go on popping your knuckles,Dr.Swezey says if OK,even if his son's grandma still doesn't like it.
28.People who hear others cracking their knucklesA.
A.are bothered.
B.don't notice the sound
C.start to crack their own knuckles.
D.feel it's as had as slurping soup.
29.When Dr.Swezey went to the old-age-home,what did he find out about old people who had cracked their knuckles?C
A.Only one old people had something wrong with their finger joins.
B.Only old women had cracked their knuckles.
C.About 6.7percent of the old people had something wrong with their finger joints.
D.The old people were all well.
30.Which of the following is right?D
A.Slurping soup and popping bubble gum are food habits.
B.Cracking knuckles will lead to arthritis.
C.No one likes cracking his knuckles.
D.Some women who didn't crack their knuckles had something wrong with their finger joints.
31.If you pop your knuckles,Dr.Swezey thinks you might as wellA.
A.go on doing it.
B.stop at once.
C.avoid people who do it.
D.not do it around your friends.

Computers have beaten human world champions at chess and, earlier this year, the board game Go. So far, though, they have struggled at the card table. So we challenged one AI to a game.

Why is poker(扑克)so difficult? Chess and Go are “information complete” games where all players can see all the relevant information. In poker, other players’ cards are hidden, making it an “information incomplete” game. Players have to guess opponents’ hands from their actions----tricky for computers. Poker has become a new benchmark for AI research. Solving poker could lead to many breakthroughs, from cyber security to driverless cars.

Scientists believe it is only a matter of time before AI once again vanquishes humans, hence our human-machine match comes up in a game of Texas Hold’s Em Limit Poker. The AI was developed by Johannes Heinrich, researcher studying machine learning at UCL. It combines two techniques: neural(神经的)networks and reinforcement learning(强化学习).

Neural networks, to some degree, copy the structure of human brains: their processors are highly interconnected and work at the same time to solve problems. They are good at spotting patterns in huge amounts of data. Reinforcement learning is when a machine, given a task, carries it out, learning from mistakes it makes. In this case, it means playing poker against itself billions of times to get better.

Mr Heinrich told Sky News: “Today we are presenting a new procedure that has learned in a different way, more similar to how humans learn. In particular, it is able to learn abstract patterns, represented by its neural network, which allow it to deal with new and unseen situations.”

After two hours of quite defensive play, from the computer at least, we called it a draw.

1.Why can’t the computer beat humans at the poker game?

A. Because humans are cleverer than the computer

B. Because humans practice playing the poker game every day

C. Because the computer can’t know the other players’ cards completely

D. Because the computer can’t learn the regular rules of the poker game

2.What does the underlined word “vanquishes” in Paragraph 3 mean?

A. Leaves B. Defeats C. Cheats D. Serves

3.What do we know about the reinforcement learning of AI?

A. It solves problems correctly every time

B. It is the same as the learning of humans

C. It learns from the mistakes appearing in a task

D. It is more developed than the studying ways of humans

4.What can be inferred from the text?

A. The new procedure of AI has some features of humans

B. Computers are stronger than humans in every aspect

C. Humans will beat computers at playing poker forever

D. Scientists feel unhappy about the result of the poker game
