1.When Bonfield,the chief of the Women's Engineering Society,recently attended a military air show,she was in great shock.
There were around 900 girls among the crowd and Ms Bonfield said,"I'm saying to all these girls,'Do you know about engineering?Would you like to be an engineer?Have you thought about engineering?'And in the whole day…probably five or six of them said yes.Every other one said no,just straight out no."
What surprised her most wasn't that these girls didn't know what engineering was.It was simply that they had already switched off.They had lost interest in engineering."So how much work does it take to change that?"asked Ms Bonfield,"I mean it's huge."
There's no shortage of data to back up her ideas.The latest figures from the Office for National Statistics show that women make up around just 8% of engineers in the UK.And this is at a time when the UK needs to produce thousands more engineers,so much that the inventor,Sir James Dyson,is planning to open his own institute to deal with the skills shortage.
One of the reasons why girls don't choose engineering is that there are not enough female role models.The attitude of parents is also an important factor in career choices.For girls,perhaps unsurprisingly,mothers are particularly influential.
"My mum was a bit uncertain about it at first,"said middle school student Hannah,"But my dad used to build a lot of stuff and he got me into that.So after my mum saw how me and my dad interacted,she said,'Yeah,go for it'and she's kind of the one who supported me with this."

28.What greatly surprised Bonfield at the military air show?D
A.So many girls came for the air show.
B.Quite a few girls had interest in engineering.
C.Girls were not interested in the air show.
D.Girls had shut their door to engineering.
29.Sir James Dyson hopes to set up his own institute toB.
A.invent more new things                                             
B.handle the shortage of engineers
C.a(chǎn)llow more girls to receive higher education                
D.create more jobs for girls
30.What made Hannh finally choose engineering?C
A.Her mother's encouragement.
B.The demand of society for engineers.
C.Her father's positive influence on her.
D.Her born interest in engineering.
31.What is the author's purpose of writing the passage?A
A.To explain what causes the shortage of girl engineers.
B.To introduce some famous girl engineers to readers.
C.To promote the social status of female engineers.
D.To give girls advice on how to choose future careers.

18.One of the main challenges facing many countries is how to maintain their identity in the face of globalization and the growing multi-language trend."One of the main reasons for economic failure in many African countries is the fact that,with a few important exceptions,mother-tongue education is not practiced in any of the independent African states."said Neville Alexander,Director of the Project for the Study of Alternative Education in South Africa at the University of Cape Town.
In response to the spread of English and the increased multi-language trends arising from immigration,many countries have introduced language laws in the last decade.In some,the use of languages other than the national language is banned in public spaces such as advertising posters.One of the first such legal provisions(規(guī)定) was the 1994"Toubon law"in France,and the idea has been copied in many countries since then.Such efforts to govern language use are often considered as futile by language experts,who are well aware of the difficulty in controlling fashions in speech and know from research that language switching among bilinguals is a natural process.
It is especially difficult for native speakers of English to understand the desire to maintain the"purity"of a language by law.Since the time of Shakespeare,English has continually absorbed foreign words into its own language.English is one of the most mixed and rapidly changing languages in the world,but that has not been a barrier to acquiring superiority and power.Another reason for the failure of many native English speakers to understand the role of the state regulation is that it has never been the Anglo-Saxon way of doing things.English has never had a state-controlled authority for the language,similar,for example,to the Academic Francaise in France.
The need to protect national languages is,for most western Europeans,a recent phenomenon-------especially the need to ensure that English does not unnecessarily take over too many fields.Public communication,education and new ways of communication promoted by technology,may be key fields to defend.

32.Neville Alexander believes thatD.
A.mother-tongue education is not practiced in all African countries
B.globalization has resulted in the economic failure of Africa
C.globalization has led to the rise of multi-language trend
D.lack of mother-tongue education can lead to economic failure
33.The underlined word"futile"(in paragraph 2)most probably means"C".
A.workable       B.practical        C.useless        D.unnecessary
34.What can we infer from the last paragraph?B
A.English has taken over fields like public communication and education.
B.Many aspects of national culture are threatened by the spread of English.
C.Most language experts believe it is important to promote a national language.
D.Europeans have long realized the need to protect a national language.
35.The best title for the passage isB.
A.Fighting against the rule of English
B.Protecting local languages and identities
C.Globalization and multi-languag trend
D.To maintain the purity of language by law.

5.If your child constantly moves when he's doing math homework or insists on listening to music while studying,take heart.Although it may seem like he's trying to drive you crazy,he's probably just using the strategies that help him learn.
"I like to study at a desk in silence,and my daughter can't think that way.She likes to bounce around on a ball with music in the background,"says author Maureen McKay,whose website,Optimistic Outcomes,provides tips based on a child's learning style for parents."Sometimes kids are just doing what works for them."
Three basic learning styles are auditory,kinesthetic(肌肉運動知覺的),and visual ones.Auditory learners prefer listening to explanations to reading them and may like to study by reciting information aloud.This type of learner may want to have background music while studying,or they may be distracted by noises and need a quiet environment to study.Kinesthetic learners learn by doing and touching something.They may have trouble sitting still while studying,and they are better able to understand information by writing it down or doing hands-on activities.Visual learners process new information by reading,looking at graphics,or watching a demonstration.Children with this learning style can grasp information presented in a chart or graph,but they may grow impatient listening to an explanation.
Most people use a combination of styles but have a clear preference for one.Understanding your child's learning style can reduce homework frustrations and make it easier for families to communicate,says McKay.She observed different learning styles while working as a teacher's assistant,and she started researching strategies for working in different learning styles when her daughter began having trouble in elementary school.
Because her daughter had difficulty listening in class,McKay looked for exercises to strengthen listening skills.Her daughter is now doing well in middle school,and she owes her success to the fact that her teachers and parents came to understand her unique style of learning.

29.What does the underlined part"take heart"in Paragraph 1 mean?C
A.Take care.B.Work hard.C.Don't worry.D.Don't mention it.
30.It's implied in the passage that McKay's daughter studies inA.
A.both auditory and kinesthetic styles
B.a(chǎn) kinesthetic style
C.both visual and auditor's styles
D.a(chǎn) visual style
31.According to the passage,McKay would agree thatA.
A.parents should explore their children's learning styles.
B.teachers should reduce their students'homework
C.students always enjoy trying different learning styles
D.schools are giving up their traditional teaching methods
32.In the case of her daughter,McKayD.
A.helps a lot with her homework
B.teaches her in person at school
C.lets her read many books
D.values her personal learning style.

15.A child who has once been pleased with a tale likes,as a rule,to have it retold in almost the same words,but this should not lead parents to treat printed fairy stories as formal texts.It is always much better to tell a story than read it out of a book,and,if a parent can produce what,in the actual circumstances of the time and the individual child,is an improvement on the printed text,that's much better.
A charge made against fairy tales is that they harm the child by frightening him or making him sad thinking.To prove the latter,one would have to show in a controlled experiment that children who have read fairy stories were more often guilty of cruelty than those who had not.As to fears,there are,I think,some cases of children being dangerously terrified by some fairy story.Often,however,this arises from the child who has heard the story once.Familiarity with the story by repetition turns the pain of fear into the pleasure of a fear faced and mastered.
There are also people who are opposed to fairy stories in that they are not true,that giants,witches,two-headed dragons,magic carpets,etc.do not exist; and that,instead of being fond of the strange side in fairy tales,the child should be taught how to adapt to reality by studying history and mechanics.I find such people,I must say so strange that I do not know how to argue with them.If their cases were sound,the world should be full of mad men attempting to fly from New York to Philadelphia on a stick or covering a telephone with kisses in the belief that it was their beloved girlfriend.
No fairy story has ever claimed to be description of the real world and no clever child has ever believed that it was.

32.The author considered that a fairy story is more effectiveD.
A.when a story is repeated without any change
B.when we treat a story as a joke
C.when the story is set in the present time
D.when the parent makes some changes about a story
33.According to the passage,when can great fear take place in a child?A
A.When a story is heard for the first time.
B.When a story is in a realistic setting.
C.When a story is repeated too often.
D.When a story is told in a different way.
34.What is the advantage claimed for repeating fairy stories to young children?C
A.Encouraging them not to have strange beliefs.
B.Developing their power of memory.
C.Making them less fearful
D.Making them believe there is nothing to be afraid of.
35.The author's mention of sticks and telephones is meant to suggest thatD.
A.fairy stories are still being made up
B.there is more concern for children's fears nowadays
C.people try to update old fairy stories
D.there is some misunderstanding about fairy tales.

2.Officials say the islands of Tokelau in the South Pacific Ocean have become the world′s first territory totally powered by the sun.The move is expected to save money and ease the environmental burden of depending on imported fossil fuels.
New Zealand′s foreign affairs minister released a statement about the Tokelau Renewable Energy Project.Murray McCully said Tokelau′s three main islands now have enough solar capacity to meet all of their electricity needs.
The three islands of Tokelau are Atafu,Nukunonu and Fakaofo.The group of islands is about halfway between New Zealand and Hawaii and is administered by New Zealand.Together they have about 1500citizens.
Each island received its own solar power transmission network.New Zealand officials estimated the cost of the project to build the three solar transmission networks at around seven million dollars.The last of them was completed earlier this month.
It is estimated that oil imports make up to thirty percent of national income in some parts of the Pacific.The move to solar power could save Tokelau about one million dollars a year.One project director said Tokelau would now be able to spend more on social programs to help its citizens.
Other South Pacific islands are attempting similar projects.The island nations of Samoa and Tuvalu are aiming to get all of their electricity from renewable sources by 2020.The Cook Islands plans to start moving to solar panels and wind turbines(渦輪).And most houses in the South Pacific groups of islands will begin to use solar water heaters.
East Timor′s government has promised that no households in the capital,Dili,would be using firewood for cooking by 2015.It also says fifty percent of the country′s electricity will come from renewable sources by the end of the decade.
New Zealand Foreign Affairs Minister Murray McCully said the country would hold a Pacific energy summit in March next year.He said the meeting would build on the success of clean and affordable energy solutions for Tokelau,Tonga,and the Cook Islands.

64.From the passage we can know thatC.
A.the three islands lie close to New Zealand
B.each island has a population of about 1,500 people
C.solar power transmission networks on the three islands are separated
D.each island has spent around seven million dollars
65.Who will benefit most from the Renewable Energy Project?D
A.New Zealand officials.
B.New Zealand government.
C.The project directors.
D.Tokelau′s people.
66.What′s the main idea of Paragraph 6?A
A.Some other South Pacific islands are trying to use green energy.
B.The island nation of Samoa is trying to develop green energy.
C.The Cook Islands start moving to solar panels and wind turbines.
D.Most houses in the South Pacific groups of islands will use solar water heaters.
67.What′s the main aim of the Pacific energy summit?D
A.To prevent sea pollution.
B.To reduce the cost of building solar power network.
C.To improve the islanders′income.
D.To find ways of using new and clean energy.

19.A.When something comes from within you,you always try your best to analyze it in a scientific way.
B.Psychologists call this private speech----language that is spoken loud but directed at yourself
C.So words to the self,spoken silently or loud,are so much more than just chatter
D.We keep the private speech we use as children inside------but we never truly put away the out=loud version.
E.According to he well-known saying,talking to yourself is the first sign of madness.
F.Self-talk is efficient because when we are vocal about our thoughts,it makes a larger impact on our brain.

Self-talk helps us allTalking to yourself may seem a little shameful.If you've ever been overheard criticizing yourself for a foolish mistake or practicing a speech,you'll know the social problems it can cause.(67)E
But there's no need for embarrassment.Talking to ourselves,whether out loud or silently in our heads,is valuable.Far from being a sign of insanity,self-talk allows us to plan what we are going to do,manage our activities and control our emotions.
For example,take a trip to any preschool and watch a small girl playing with her toys.You are very likely to hear her talking to herself:offering herself directions and talking about her problems.(68)BWe do a lot of it when we are young.
As children,according to the Russian Psychologist Lev Vygotsky,we use private speech to control our actions in the same way that we use public speech to control the behavior of others.As we grow older,we keep this system inside.
Psychological experiments have shown that this so-called inner speech can improve our performance in tasks like telling what other people are thinking.Our words give us an interesting view of our actions.One recent study suggested that self-talk is most effective when we talk to ourselves in the second person:as"you"rather than"I"(69)DIf you want proof,turn to a sports channel.You're sure to see an athlete shouting at himself or herself.
Talking to ourselves seems to be a very good way of solving problems and working through ideas.Hearing different points of view means our thoughts can end up in different place,just like a regular dialogue,and might turn out to be one of the keys to human creativity.
Both kinds of self-talk-----silent and out loud----seem to bring many different benefits to our thinking.(70)C-

20.The days of having to remember your ID could soon be a thing of the past.The famous tourist town of Wuzhen,China,is now using facial recognition technology to act as its entry pass through the gates of the attraction.The system uses cameras to notice people as they approach the entry,and checks these against a database of registered visitors within a few seconds.The technology is thought to be up to 99.77percent accurate and able to distinguish people better than a human.
Wuzhen is a popular tourist town with visitors going there in large numbers to see its stunning river system and museums.Baidu,a web firm often referred to as"Chinese Google",created the system.When people now check in to their accommodation,they will have their photo taken and uploaded to a central database upon leaving and re-entering the town,the system will re-check that they are still a guest at a hotel,before allowing them back in.
The technology is being used to track the 5,000 visitors that stay in the town's hotels every day.Yuanqing Lin,director of the Institute of deep Learning at Baidu,told The Verge,"With our technology,you don't need to give your ID.When you are approaching a gate it will take a photo of you and compare that photo to the database."Wuzhen used to monitor its visitors using a ticket-entry system,but this could easily be abused.It was discovered that some people were sharing their tickets to avoid paying.
Baidu's system is based on neural networks,which can process huge amounts of dat---more than one billion faces.As well as recognizing faces,the system can also discover facial movements,so it can't be fooled by someone holding up a mask.
Baidu is also using the software for employee entry at its Beijing headquarters.

5.What can be learnt about the facial recognition technology from the passage?C
A.The technology could soon be a thing of the past.
B.The technology can be over 99.77% accurate.
C.The technology can match visitors'faces with those in the database
D.The technology is being used to track where the 5,000 visitors are going.
6.Which of the following word can replace the underlined word"stunning"in  paragraph 2?B
A.popular        B.a(chǎn)ttractive       C.brilliant      D.funny
7.How does Wuzhen monitor its visitors now?A
A.By using facial recognition technology
B.By using a ticket-entry system
C.By using ID card
