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．abandoned
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
B．Irrigation by carrying water in buckets
C．Solar-powered pumps aid African farmers
D．Vegetable supply increased in African villages．

20．New research suggests that speaking more than one language may delay different kinds of dementia（痴呆），that is the loss of mental ability．In fact，researchers say，speaking two languages appears to be more important than the level of education in defending against dementias．
A study in India examined the effect of knowing more than one language in delaying the first signs of several dementias．Researchers studied nearly 650people whose average age was 66.240of those studied suffered from Alzheimer's，the most common form of mental decline（下降）.391of the subjects spoke two or more languages．Researchers found the dementias began about four-and-a-half years later in those who spoke two languages compared to those who spoke only one language．The level of education had no effect on the age at the first sign of dementia．
Thomas Bak，from the Center of Cognitive Aging at the University of Edinburgh in Scotland，who helped to organize the study，suggests that individuals who speak more than one language train their brains by moving back and forth between different words and expressions．He also believes this effort improves what scientists called executive（执行的） functioning，which often weakens in people with dementias．He states that researchers found there was no extra gain in speaking more than two languages．
Mr Bak says it does not appear important whether you learn another language at a young age or later in life．It's not something that"you missed the boat when you do not do it as a baby．"It is something that is still quite useful and powerful when you do it as an adult．

59．The finding of the study is thatB．
A．learning more than one language can cure dementias
B．speaking two languages may delay kinds of dementias
C．the level of education matters in defending against dementias
D．people who suffer from dementias will lose mental ability
60．The underlined word"subjects"refers toA．
A．people who were studied in the study
B．notices that were put on about the study
C．questions that were asked in the study
D．methods that were used in the study
61．According to Mr Bak，C．
A．the more languages one speaks，the less chance of getting dementias
B．people's executive functioning often strengthens with age
C．when you learn one more language makes no difference
D．it is much easier to learn one more language at a young age
62．This passage may probably be seen inB．
A．a research plan    B．a health magazine
C．a book review      D．a business magazine．

19．If you see someone drowning，speed is very important．Once you get him out of the water，if he isn't breathing，you have four minutes before his brain is completely destroyed．Support his neck，tilt（使翘起）his head back and press his chin（下巴）upwards．This stops the tongue blocking the airway in the throat and is sometimes enough to get him breathing again．If that doesn't work，start mouth-to-mouth breathing．Press his nostrils（鼻孔）together with your fingers．Open your mouth and take a deep breath．Blow into his lungs until his chest rises，then remove your mouth and watch his chest fall．Repeat twelve times a minute．Keep doing until help arrives．
To bring a child back to life，keep your lips around his mouth and nose and gently blow into his mouth．Give the first four breaths as quickly as possible to fill the blood with oxygen．If，in spite of your efforts，he starts turning a blue grey color，you can feel no pulse（脉搏），then pressing is the last chance of saving his life．
With arms straight，rock（摇动）forwards，pressing down on the lower half of the breastbone．Don't be too hard or you may break a rib（肋骨）．Check how effective you are seeing if his color improves or his pulse becomes independent to your chest pressing．If this happens，stop the pressing．Otherwise continue until  rescue arrives．

31．This passage is mainly aboutB．
A．how to save people out of the water

B．blowing air into his mouth is sure to save his life
C．pressing his nostrils together with your fingers can work
D．pressing his chest is the last chance of saving his life
35．Which of the following statements is true？A
A．If a man fails to breathe for four minutes，his brain will be completely destroyed．

17．My dad was never the kind to offer many words of love or encouragement．But we knew he loved us…he just had his own way of showing it．
When I was a teen，we were seasonal campers at a family campground almost an hour outside the city where we lived．Each family had their own campsite with water and electric，and you basically parked your camper there from May through October．Most"Seasonals"visited them every weekend during those months，with the occasional weeklong stay．There were plenty of other kids who camped seasonally each weekend，and they came to be some of my closest friends．Of course，many of them were boys．
We kids paired up with our little boyfriends or girlfriends，and we'd hold hands as we'd walk around the campground．We'd play ping-pong，have some snacks，and play songs．Most weekends were pretty similar，but the couples would change．You'd see so-and-so with a different so-and-so than they were with the weekend before．You know how it is when you're a teen-a three-week relationship is a really long time．
So，needless to say，my teen years were spent with quite a few different boys．But every single one of them had something in common…they'd all received The Evil Eye．
The Evil Eye was a magical sort of thing．One simple look from my dad，and the boy immediately knew not to mess with me．It was as if he could send his warnings through invisible laser（激光）beams that shot directly from his eyes to the boys'brains．
"You will not put your hands on my daughter…You will not kiss my daughter…You will not even whisper sweet nothings into my daughter's ear．"
I remember one night in particular，walking with a boy around the campground after dark．We came from one direction，and my dad from the other．The boy and my dad locked eyes for a brief second，then the boy dropped my hand like a hot potato and turned away，giving me a quick，"See you later．"
Yes，the Evil Eye．Best way ever to keep wandering teen boy hands away from your daughters．

56．The Evil Eye in the passage implies thatD．
A．Dad gets angry easily
B．Dad's eyes are like evil's
C．Dad's eyes are ugly-looking   
D．Dad's eyes are protective to his daughter
57．The underlined words"mess with"in paragraph 5most probably meansB．
A．make untidy  B．cause trouble  C．get married to  D．talk to
58．It can be inferred from the passage that the authorC．
A．is a teenage girl who loves her father
B．is a teenage boy who hates his father

D．used to be a naughty boy who changed girlfriends now and then．

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 （叶绿素）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．

D．How Do Trees'Food Factories Work？

15．After an earthquake most survivors can be expected to recover over time，especially with the support of family and friends．Some families will be able to return to their normal life quickly，but others will have to  contend with  the destruction of their homes，medical problems，and injury to family members．Children especially will need time to recover from the loss of a loved one or a pet or from the closing down of their school．
Children often come to adults for information，comfort and help．Parents should try to remain calm，answer children's questions honestly and remain understanding when they see changes in their children's behavior．
Children react（反应） differently to an earthquake depending on their ages，developmental levels and former experiences．Some will remain silent and not communicate with people，while others will have angry outbursts（爆发）．Parents should keep an eye on each child's reactions．Parents should spend time talking to their children，letting them know that it's OK to ask questions and to share their worries．
Although it may be hard to find time to have these talks，parents can use regular family meal times or bed times for them．They should answer questions shortly and honestly and be sure to ask their children for their opinions and ideas．Problems may come up more than once and parents should remain patient when you answer the questions again．After talking about the earthquake with young children，parents might read their favorite story or have a relaxing family activity to help them calm down．Parents should also tell children they are safe and should spend more time with them．They could play games outside or read together indoors．Most importantly，be sure to tell them you love them．

C．Children should turn to their classmates for help after an earthquake．
D．Children react in the same way as adults do to an earthquake．

14．A team of US psychologists（心理学家） have found that talking to another person for ten minutes a day helps with memory．
"Socializing is just as effective as more traditional kinds of mental exercise in boosting memory and intellectual （智力的） performance，"Oscar Ybarra，a psychologist at the University of Michigan Institute for Social Research，said in a statement．
In one investigation，they analyzed data on 3610people，aged 24to 96．
They found that the higher their level of social interaction（交流），the better their cognitive （认知的）functioning．Social interaction includes getting together or having phone chats with relatives，freinds and neighbors．
In another experiment，the researchers conducted lab tests on 76college students，aged 18to 21，to evaluate how social interactions and intellectual exercises affected the results of memory and mental performance tests．
The students were divided into three groups：the social interaction group had a discussion of a social issue for 10minutes before taking the tests； the intellectual activities group completed three tasks （including a reading comprehension exercise and a crossword puzzle） before the tests； and a control group（对照组）watched a 10-minute clip（电影片段）of the Seinfeld television show．
"We found that short-term social interaction lasting for just 10minutes improved participants'intellectual performance as much as engaging in so-called'intellectual'activities for the same amount of time，"Ybarra said．
The study was expected to be published in the February issue of the journal Personality and Social Psychology Bulletin．

C．Watching TV at home alone．
D．Calling your classmates
58．What's the purpose of the experiment on 76college students？A
A．To judge the effect of social interaction on memory and intelligence．
B．To find out what is real social interaction．
C．To learn how much time is needed for social interaction．

C．Communicating with others keeps you healthy．
D．Social interaction makes you smart．

13．If your child has mobile internet access，it will be more difficult to monitor（监督） and control his or her internet use．Kids are turning to the internet for everything from hanging out with friends to shopping，which makes it harder for parents to keep track of their online activities．Fortunately，there are many choices for controlling what your kids see on their computers，laptops，and mobile devices．
Content blockers and filters are great tools to use for younger kids．They allow you more control over where they go and what they do online．A content blocker can block some unhealthy websites or limit a child's search to the kind of sites．A content filter can scan sites and pictures and block those sites that contain certain words，key phrases，or content．
Consider tracking software for older teenagers．This software enables you to see which sites your children have visited，tracking their path online．This tool gives young people more freedom to explore the Internet，but it also allows you to check that they are using the internet responsibly．Let your teenagers know that you trust them，but that you will be regularly checking that they are visiting appropriate sites online．
Even if you use content blockers，filters，and trackers，you know that a lot of kids figure out ways to get around these，so it's important to remain alert（警惕的）．Remember that not all adult sites can be identified by blocker，filter，or tracker software．That's why it's important to talk to your kids about what to do when something inappropriate or scary comes up．Nothing can replace involvement and supervision（监督） by adults．Keep monitoring how your kids use the internet on a regular basis without getting into the role of internet traffic police．
