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．

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．

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．

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
