1.Scientists around the world have been studying the warming of waters in the Pacific Ocean known as El Nino.The appearance of El Nino is known to affect the weather around the world.Scientists still do not completely understand it.Yet they now find they can use it to tell about the future in different areas of the world.
One example is the work of two scientists at Columbia University in New York,Mark Cane and Gordon Eshel.A scientist of Zimbabwe(津巴布韋),Roger Buckland worked with them.They have found that when El Nino appears,Zimbabwe has little or no rain.This means corn crops in Zimbabwe are poor.The last El Nino was in 1991to 1993.That was when southeastern Africa suffered a serious lack of rain.
The scientists wrote about their recent work in the publication Nature.Their computer program can tell when an El Nino will develop up to a year before it does.They suggest that this could provide an effective early warning system for southern Africa,and could prevent many people from starving.
33.El Nino is known asB.
A.the changing of the weather in southern Africa
B.the warming of waters in the Pacific Ocean
C.the weather which brings drought(旱災)to Africa

34.Scientists study El Nino in order thatA.
A.they can provide a kind of early warning to the place that will suffer from drought
B.they can tell why Zimbabwe has little or no rain
C.they can do some research work in this field.
D.they can put all this information into their computers.
35.Which of the following is TRUE according to the passage?D
A.Scientists come to understand how El Nino appears.
B.Three scientists from the USA work on this subject.
C.Southern Africa suffered a serious drought and many people died from hunger.

11.The US plans to extend its endangered species protection to lions in Africa.US Fish and  Wildlife Service(FWS)will classify lions in southern and eastern Africa as threatened.The  move will place tighter restrictions on the import of lion"trophies",such as paws or heads.
While the US cannot regulate hunting in other countries,the move is significant because around half of a11lion hunting in Africa is conducted by Americans.According to FWS data,more than 5,600lions have been killed and imported by American hunters over the past    decade.
Under the new FWS rules,bringing lion parts to the US will be banned in most circumstances if the animal is from a country where lions are endangered.Hunters will have to show the trophies were"legally obtained"from countries that have"a scientifically sound management program that benefits the subspecies in the wild".
This regulation is expected to place a far greater burden of proof upon hunters who claim  that the money from lion hunting has been used to help communities in Africa and the overall  conservation of lions.The persistent downward trend in lion numbers,due to habitat loss and hunting by locals and foreign tourists,suggests there has been little conservation benefit from organized hunts.
An international study,published in September,found African lion numbers have    decreased by half since 1993,with a further 50%decline expected over the next 20years for    populations in west,central and east Africa.
"The lion is one of the planet's most beloved species and an irreplaceable part of our shared global heritage,"said Dan Ashe,director of the FWS."If we want to ensure that healthy lion populations continue to wander around the African savannas and forests of India,it's up to all of us-not just the people of Africa and India-to take action.

28.Why will lions be classified as endangered in southern and eastern Africa?C
A.No lion is protected in Africa.
B.Lion trading has been banned.
C.Its numbers have been decreasing.
D.Both locals and tourists hunt lions.
29.Where do most of the lion hunters come from?B
A.Southern Africa.
B.America.  
C.Eastern Africa.
D.India.
30.What may be the result of the move?A
A.The import of lion parts will be strictly limited.
B.Lion-hunting will be illegal all over the world.
C.Communities in Africa will benefit a lot.
D.Lion parts will not be legally obtained.
31.What does Dan Ashe really want to tell us in the last paragraph?B
A.Almost everybody loves lions.
B.It's everyone's duty to protect lions.
C.Lion populations will increase rapidly.
D.Measures must be taken to keep lions fit.

16.The way food is labeled(標簽) affects how much eat of it,according to new research.Scientists have discovered that people tend to eat more of a portion (部分) if they believe it to be regular or small".However,if a portion is termed as being"large",people tend to leave some of the food they have-been given.
Dr Brian Wansink and Dr David Just,of the Food & Brand Labat Cornell University,have discovered that people tend to eat more of an item if its size is termed"regular"than if it's termed"double size"-even if the actual portion is the same.
"If  labels are used as size information,policies governing normative (規(guī)范) names could help reduce the consumption of food or reduce waste,"the researchers wrote in the Study.For the study,researchers served participants either one portion of a lunch item,or two portions.
For some of the participants,the single portion of food was called"half-size"and the double portion was called regular",while.For the other participants,the single portion was called"regular"and the double portion was called"double size".
Researchers found that participants ate more when eating from the"regular"-labeled portion,compared with eating from the"double size"-labeled portion,even though the portion sizes were exactly the same.Dr Wansink and Dr Just also discovered that a person's willingness to pay for food was also dependent on food labels.If a food is considered a Half-size,they are only Willing to pay half the price as a"regular"portion,-even if the actual portion sizes do not reflect their labels.
Dr Wansink and Dr Just previously found that the color of a plate could influence how much a person ate.Research also found that people served food on tables with a higher color contrast (反差 ) between the plate and the tablecloth ate more than those who were served the same amount of food without an obvious contrast.
28.According to the study,we can know that people tend toC
A.eat less if they believe it to be regular or small
B.eat more when the label is double-sized than it is regular
C.leave some of the food if a portion is termed being large
D.eat more if policies government normative names are signed
29.In the research we can know thatA
A.the portion size of 2labels were exactly the same
B.participants eat less when eating from the regular labeled portion
C.a person's willingness to pay for food is not dependent on food labels
D.the use of color could influence the quantity of food people have
30.What is the main idea of the last paragraph?D
A.people should use the contrast to eat more
B.the plate and the tablecloth should be the same color
C.people will eat less when the plate is white and black
D.the use of color could influence the quantity of food people have
31.Where is the study most probable published?C
A.in the journal of Sport Report

6.Long ago,sailors sailed to faraway places without the ability to rely on modern instruments to lead the way.Still,many were able to sail across vast,uncharted oceans and arrive at their destinations safely.Why didn't more sailors get lost at sea?What kinds of equipment did they use to find their way?
In early sailing history,few maps were available.Sailors had to rely on memory and on written guides called pilot books.Pilot books offered sailors information about how long it took to get to certain ports and instructions about getting in and out of the ports.Pilot books did not offer much information about sailing far from land.
Later,sailors used maps,charts,and information from other explorers to plan their trips.Early maps and charts offered descriptions of islands and coastlines tht helped sailors navigate.Experienced sailors learned where harbors,fresh water,supplies,and riendly people might be found.They were also able to warn others about dangers.Some of the early navigation practices and equipment used on these ships proved to be quite trustworthy.Early sailors used a tool called the astrolabe (星盤) to figure out the positions of stars and the sun to determine their location.For centuries,sailors planned their routes,sailed,and recorded their progress using the North Star as their only reference.They also used patterns of wind and waves as directional clues.Even though ocean waves may look the same to inexperienced eyes,they have different shapes related to the depth of the ocean and their closeness to land.Sailors even found a way that clouds and seabirds could help them.
The sailors of yesterday relied heavily on their observations and studies of the sea.Although their techniques were simple,they were able to achieve great things during their adventures at sea.
28.According to the text,pilot booksA.
A.are maps charted by other sailors   
B.are guides written by other sailors
C.offer descriptions of islands and ports

13.When 7-year-old Warren Buffett said,"I will be the richest man one day,"his friends made fun of his"daydreaming".But ever since then the little boy has set about learning how to make money by selling drinks,delivering newspapers and buying stocks.The American had already earned 9,000 (equal to 90,000today) by the time he graduated from high school.
And this month the 78-year-old man,who earned his fortune by making a lot of sound investment in the stock(股票)market,took the place of Microsoft founder,Bill Gates,as the world's richest man.Gates'worth declined 1.5billion to 55.5billion in 33days after the recent financial storm,according to Forbes Magazine.
Buffett,the only son of a stockbroker,was ready to think outside the box to develop his business from a very early age.At 8,he went to golf courses collecting and selling the used balls.At 11when he sold soda pop door-to-door with a friend,the pair collected lids on streets to judge which flavor was the most popular.
As a paper boy during high school,Buffett delivered two competitor papers,so that even when customers canceled one of the subscriptions,he could still make a profit from the other.With his paper delivery savings,Buffett bought 162,000square meters of farmland and collected rent.Young Buffett stepped into the stock market at 11but earned only 5.The experience taught him one of the virtues in investing,patience.
After graduating from university,Buffett started his venture with stocks with his childhood earnings and money from friends.He researched the stocks and just bought those of solid companies that were undervalued and inexpensive at the time.By sticking to companies such as American Express and Coca-Cola,Buffett has become rich.
"Learning is important to Buffett's success.He is a learning machine who can spend his entire day reading.He keeps learning from books,street smarts and investigation,from both success and failure.In this way,he over-achieved his aptitude (能力)."said Charlie Munger,his longtime business partner.
32.The passage is mainly aboutD.
A.why Buffett took the place of Bill Gates as the world's richest man
B.what effect Buffett's childhood experiences had on his success
C.what Buffett dreamt about when he was a child
D.how Buffett earned his fortune and achieved his aptitude
33.Which of the following is true about Buffett?C
A.He is next to Bill Gates in wealth at the present time.
B He achieved great success on stepping into the stock market.
C.His worth is more than 55.5billion now.
D He bought 162,000square meters of farmland by selling soda pop.
34.Which is the main factor that determines Buffett's success?B
A.His degree of education.
B.His eagerness to absorb the knowledge.
C.His family background.
D.His cooperation with his partner.
35.What can we infer from the passage?D
A.Buffett is an immediate success in the stock market.
B.Buffett and Gates are business partners.
C.His father helped him a lot in his business.
D.Buffett has a good sense of business.
