1．A new study in West Africa shows how farm irrigationsystems powered by the sun can pro-duce more food and money for villagers． The study-in Benin found that solar-powered pumpsare effective in 8upplying water，especially during the long dry season．
    Sub-Saharan Africa is the part of the world with the least food security． The United Na-tions Food and Agriculture Organization estimates that more"than one biillion of the world's peo-ple faced hunger last year．Around 265 million of them live'south of the Sahara Desert：Lack of  rainfallis one oftheir main causes offood shortages．．
    Jennifer Bumey from Stanford University in Califomia led the study．The research team helped build three solar-powered drip irrigation-（滴灌），systems in northem Benin． Between 30 and 35 women used each system to pump water from the ground or a stream．Each woman was responsible for farming her own 120 sqrurre meters of land． They also farmed other land  collectively．
    The solar-powered irrigation systems produced an average of nearly two tons of vegetables per montb． During the first year，the women．kept a monthly average of almost rune kilograms of vegetables for home use．They sold the surplus produce at local markets． The eamings greatly increased their ability to buy food during the dry season which can last six to nine months． Peo-ple in the'two villages with the systems were able to eat three to five more servingsof yegetables per day．But making the surplus available at markets also had a wider effect．
    The study compared the villages with two others where women farmed with traditional methods like carrying water in buckets． The amount of vegetables eaten in those villages also  increased，though not as much．The researchers note that only four percent of the croplamd in sub-Saharan Africa is irrigated． Using solar power to pump water has higher costs at first． But    the study says it can be more economical in the long term than using fuels like gasoline，diesel  or kerosene． And solar power is environmentally friendly．
66．Food security in Sub-Saharan Africa is insufficient mainly because ofA
A．lack of rainfall                 B．limitation of farmland
C． a small crop variety            D．little sunLight
67．From the third paragraph we know that．B
A．water is wasted by using the system
B． the farmers imgate the land together
C． all farmers use irrigation systems in northem Benin
D． the solar-powered systems take up more manpower
68．The underlined word"surplus"in the 4th paragraph most probably meansC
A．special       B．unnecessary    C．extra．     D．a(chǎn)bandoned
69．Usinf．solar power to pump water has advantages EXCEPT thatA
A．solar energy has higher cost at first
B．solar power helps to protect environment
C．solar power helps farmers increase eanungs
D． solar energy can be more economical in the long run
70．What can be the best title for the text？C
A．Manpower affects rainfallin Africa

11．THE STORY OF AN EYEWITNESS
by Jack London
Never before in history has a city been so completely destroyed．San Francisco is gone．Nothing is left of it but memories and some houses far from the centre of the city．Its businesses are gone．The factories，hotels and palaces are all gone too．Within an hour after the earthquake，the smoke of San Francisco's fires could be seen 160kilometres away． ①The sun was red in the dark sky．There was no stopping the fires．There was no way to organize or communicate．The steel railway tracks were now useless．And the great pipes for carrying water under the streets had burst．All of the ways man had made to keep the city safe were gone in the thirty seconds the earth moved．
②Out at sea it was calm．No wind came up．Yet from every direction-east，west，north，and south，strong winds blew upon the unlucky city．Man himself had to make ruins of some of the city's best buildings so that they would not be a danger to those in the streets．A list of buildings undestroyed was now only a few addresses． ③A list of the brave men and women would fill a library．A list of all those killed will never be made．
Amazing as it may seem，Wednesday night was a quiet night．There were no crowds．The policemen said nothing； even their horses were quiet． ④There were no shouts or people doing crazy things．In all those terrible hours I saw not one woman who cried，not one man who was excited．Before the fires，through the night，thousands and thousands of people who had lost their homes left for safety．Some were covered in blankets．Sometimes whole families put everything they owned and could save into wagons （四輪馬車）．They helped one another climb the high hills around the city．Never in all San Francisco's history were her people so kind as on that terrible night．

31．We can judge from the passage that the terrible earthquake took place inD．
A．China
B．Britain
C．Canada
D．America
32．Which word best describes how the writer felt about the earthquake？B
A．lost

C．excited
D．quiet
33．Which of the underlined sentences is NOT an example of contrast（對比）？D

A．The terrible earthquake lasted about one hour．
B．People hid in the library during the earthquake．
C．The quake almost destroyed everything in the city．
D．People were in panic （恐慌），not knowing what to do．
35．We could probably read the passage fromA．

9．There's no place in the world like Venice，Italy．Called the City of Water，Venice was built about 1，500 years ago．It's made up of 118 tiny islands in the Adriatic Sea．The area，however，may be in over its head．But now scientists have a new plan to save the city．
Because the city was built on soft soil，it has been sinking under the pressure of its own weight．Scientists estimate that Venice sinks at a rate of nearly 2 inches every 100 years．Rising sea levels could make Venice go under even faster，some experts say．Earth's temperature is slowly increasing．That is causing sea ice to melt，which makes the world's waters rise，they say．
To keep the city afloat，experts want to pump about 40 billion gallons of sea water beneath Venice．The liquid would expand the sand under the city，which would help support the islands，explains lead scientist Giuseppe Gambolati．
Experts are rushing to save Venice because of its rich history．The city was once a strong sea power．"Many famous artists and opera singers have come from Venice．Some of the world's greatest paintings can be found on the city's museum walls，"explains Melissa Conn，who is a director of Save Venice Inc．
While scientists work to get their water-pumping plan approved，Venice's residents go about their normal routines．When the tide rolls in，the locals have ways of keeping everyone dry．Cafe owners move tables to higher ground，and hotels pass out high boots to guests．
Still，dealing with the rising water does not give the city's residents a sinking feeling，just ask Erla Zwingle．She has lived in Venice for 17 years．"There has always been high water in Venice．"Zwingle told WR News．"If high water really were a serious problem，people wouldn't be still living here．"
56．What's the main reason Venice is sinking？C
A．Its population is rising．
B．Its buildings are too weighty．
C．The soil it was built on is not solid．
D．Its underground water is being overused．
57．What can we know about Venice from the passage？D
A．It sinks at a rate of 2 inches every 200 years．
B．It has a history of more than 1，500 years．
C．It has been in a very dangerous situation．
D．It was once a strong sea power．
58．According to Melissa Conn，VeniceB．
A．is not protecting properly  
B．deserves the world's attention
C．is best-known only for its artists  
D．has difficulty surviving the rising temperature
59．What's the local residents'attitude towards their sinking city？D
A．Worried．B．Disappointed．C．Concerned．D．Optimistic．
60．What is the main idea of the passage？D
A．Venice is a city with a long history．
B．Experts report that Venice sinks at a fast rate．
C．Venice was once a powerful country．
D．Scientists have a new plan to protect Venice from sinking．

16．We all enjoy the colors of autumn leaves．The changing fall leaves never fail to surprise us．Did you ever wonder how and why a fall leaf changes color？Where do the yellows and oranges come from？To answer those questions，we first have to understand what leaves are and what they do．
Leaves are nature's food factories．Plants take water from the ground through their roots．They take a gas called carbon dioxide from the air．Plants use sunlight to turn water and carbon dioxide into oxygen and glucose（葡萄糖）．Oxygen is a gas in the air that we need to breathe．Glucose is a kind of sugar．Plants use glucose as food for energy and as a building block for growing．The way plants turn water and carbon dioxide into sugar is called photosynthesis（光合作用）．A chemical called chlorophyll （葉綠素）helps make photosynthesis happen．Chlorophyll is what gives plants their green color．
As summer ends and autumn comes，the days get shorter and shorter．This is how the trees"know"to begin getting ready for winter．
During winter，there is not enough light or water for photosynthesis．The trees will rest，and live on the food they stored during summer．They begin to shut down their food-making factories．The green chlorophyll disappears from the leaves．As the bright green dies away，we begin to see yellow and orange colors．Small amounts of these colors have been in the leaves all along．We just can't see them in summer，because they are covered up by the green chlorophyll．
The bright reds and purples we see in leaves are made mostly in the fall．In some trees，like maples，glucose is trapped in the leaves after photosynthesis stops．Sunlight and the cool nights of autumn cause the leaves to turn this glucose into a red color．The brown color of trees like oaks is made from wastes left in the leaves．

36．The writer asked some questions in the beginning in order toD．
A．persuade readers to believe something
B．offer something to think over
C．get the readers excited
D．introduce the topic of the passage
37．Which of the following is TRUE about photosynthesis？B
A．Oxygen and water are produced by plants．
B．Glucose provides energy and food for plants to grow．
C．Sunlight is turned into sugar as plants'food．
D．Glucose produces chlorophyll that plants need．
38．Leaves are green in summer becauseA．
A．green chlorophyll offers a green color for leaves
B．sunlight turns water and carbon dioxide into a green color
C．there are no other colors in the leaves except green
D．glucose gives leaves their green color
39．Which of the following is TRUE according to the passage？C
A．Trees don't change colors with seasons．
B．Trees can still perform photosynthesis well in winter．
C．Trees have colors like yellow and orange even in summer．
D．Trees don't need food in winter．
40．What can be the best title of the passage？C
A．We Love the Beautiful Fall Leaf Colors        
B．Chlorophyll and the Fall Leaf Colors
C．Why Do Leaves Change Color in Fall？
D．How Do Trees'Food Factories Work？

6．"Slow City"-a recently launched project focused on preserving the traditional quality of life enjoyed in some of Italy's smaller cities and towns．The project was born from the idea of the"Slow Food"movement-started in Italy in the 1980s-which promotes leisurely eating and the growing of local，healthy products to fight against the American fast-food style．
"The American urban model has invaded our cities，making Italian towns look the same．We want to stop this kind of globalization，"says Paolo Saturnini，an Italian mayor．
The"Slow City"project plans to emphasize the rich，cultural，culinary（廚房的） and artistic local traditions of each community．
Walking areas will be enlarged and squares and parks will be made greener with more plants．Car alarms and other noise that disturbs the peace will be banned，and ugly TV aerials（天線），advertising posters，and signs will be taken down．
City councils will also insist on the use of recycling and renewable energy sources，and will also introduce ecological transport systems．Parking will be made stress-free by creating more public parking areas，and easily accessible walkways and bike lanes will cross the city．But in the"Slow City"way，all improvements will probably come about slowly．
Thirty-two Italian city councils，which joined the"Slow City"program，have decided to take further steps in this direction by increasing the numbers of traditional family-style eating establishments，reducing noise pollution，and concentrating on making their towns friendlier for people to live in．
Organic local produce will be promoted in all restaurants and genetically modified foods（轉(zhuǎn)基因食品） will be banned．"We can't stop large，fast-food chains from coming here，but we hope that people who come to our towns will not want to eat exactly the same hamburger they can eat in Melbourne，London or Paris，but want something genuine and different，"said Saturnini．
67．According to the passage，the"Slow City"project aims atD．
A．preventing Italy from being affected by America
B．beautifying the environment of small Italian cities and towns
C．calling on Italians to enjoy stress-free life
D．protecting the traditional Italian lifestyle
68．From Paragraphs 4-5，we can infer thatC．
A．cars in"Slow City"will have to go slowly
B．people can park their cars free of charge in"Slow City"
C．"Slow City"will take on an environmentally friendly look
D．a(chǎn)dvertising in"Slow City"will be banned 
69．Further measures will be included in the"Slow City"program EXCEPTC．
A．cutting down noise pollution
B．stop genetically modified foods
C．getting more towns involved in the project
D．building more family-style restaurants
70．In Saturnini's opinion，when traveling in"Slow Cities"，visitorsD．
A．a(chǎn)ren't provided with fast food
B．will see few fast-food chains
C．can enjoy themselves like in London
D．can enjoy real Italian-style healthy food．

13．It is winter in many parts of the world．For some areas，that means snow．Maybe even lots of snow．If you don't have to drive in it or remove it，snow can be very beautiful．When snow covers everything around you，the world looks like a"winter wonderland"．That is the name of a very popular song about winter．Richard Smith and Felix Bernard wrote the song back in 1934．There are hundreds of recordings of this happy song．
But winter is not always such a beautiful and happy time．It's cold outside．You try hard to keep warm．The days are darker and shorter．The sun rarely shines．The leaves on the trees are brown．It isn't surprising that some people are sad in winter．And some people dream about being somewhere else where it's warm and pretty-like the state of California．The Mamas and the Papas recorded this famous song"California Dreaming"．
    During the 1960s，many other famous rock groups released songs about winter．Here is a poetic song by Simon and Garfunkel called"A Hazy Shade of Winter"．They sing about life and hope and possibilities．
In 1968，the group Blood，Sweat and Tears recorded this gentle，sad song about winter．They sing about a lost love and forgotten memories in"Sometimes in Winter"．
In the early 1990s，Tori Amos wrote and recorded the beautiful song called"Winter"．She enjoyed singing about winter when she was a child．
    Finally，on a happier note comes this song written and recorded by Fountains of Wayne in 2003．They sing about a snowstorm in a New England town．Nothing unusual there．But instead of being sad or tense about the snow，they write a song about it．

11．In the fall of 1985，I was a bright-eyed girl heading off to Howard University，aiming at a legal career and dreaming of sitting on a Supreme Court bench somewhere．Twenty-one  years later I am still a bright-eyed dreamer and one with quite a different tale to tell．
My grandma，an amazing woman，graduated from college at the age of 65．She was the
first in our family to reach that goal．But one year after I started college，she developed cancer．I made the choice to withdraw from college to care for her．It meant that school and my personal dream would have to wait．
Then I got married with another dream：building my family with a combination of adopted（收 養(yǎng)的） and biological children．In 1999，we adopted our first son．To lay eyes on him was Fantastic and very emotional．A year later came our second adopted boy．Then followed son No.3．In 2003，I gave birth to another boy．
You can imagine how fully occupied I became，raising four boys under the age of 8!Our
home was a complete zoo-a joyous zoo．Not surprising，I never did make it back to college full-time．But I never gave up on the dream either．I had only one choice：to find a way．That meant taking as few as one class each semester．
The hardest part was feeling guilty about the time I spent away from the boys．They often wanted me to stay home with them．There certainly were times I wanted to quit，but I knew I should set an example for them to follow through the rest of their lives．
In 2007，I graduated from the University of North Carolina．It took me over 21 years to get my college degree!
I am not special，just single-minded．It always struck me that when you're looking at a big challenge from the outside it looks huge，but when you're in the midst of it，it just seems normal．Everything you want won't arrive in your life on one day．It's a process．Remember：
little steps add up to big dreams．
21．When the author went to Howard University，her dream was to beC．
A．a(chǎn) writer         B．a(chǎn) doctor　　　　C．a(chǎn) judge         D．a(chǎn) journalist
22．Why did the author quit school in her second year of college？D
A．Her grandma asked her to withdraw from college．
B．She fell in love and got married．
C．She had so many children to support that she was too busy to continue her college．
D．She decided to look after her grandma．
23．What does the author mostly want to tell us in the last paragraph？B
A．Failure is the mother of success．
B．Little by little，one goes far．
C．Every coin has two sides．
D．Well begun，half done．
24．Which of the following can best describe the author？A
A．Caring and determined．
B．Honest and responsible．
C．Ambitious and sensitive．
D．Innocent and single-minded．
