12．Fujitsu，a Japanese technology company，has created a system capable of simultaneously（同时地）charging multiple portable electronic devices such as mobile phones，digital cameras and laptop computers without the need for cable connections．
Electric cars users may also eventually be able to charge their vehicles wirelessly using the same technology，said the company，which developed a sample system at Osaka Prefecture University．Claiming to be the world s first of its kind，the technology works on the basis of the transmission of electricity using magnetic fields between the charger and the electronic device．
The system enables wireless charging at distances of up to several meters．With the final aim of installing public"charging spots"on the streets in order to enable easy charging around the clock，scientists at Fujitsu Labs are planning to commercially sell products incorporating the new wireless charging system as early as 2012 but have not yet decided how much they would cost．
‘This technology paves the way to integrating compact wireless charging functions into mobile phones and enabling multiple portable devices to be charged simultaneously without any restrictions on their position relating to the charger，"the company said in a statement．
Mobile phone users in Japan can currently charge their batteries using the disposable portable plug-in battery 一 operated device，available at most train stations and convenience stores．However，phone companies warn long time use of it can damage the phones．
The company added，"We are also looking at applying the results of this work to fields other than portable electronics，including power transmission between circuit boards （电路板）or computer chips，and providing mobile charging systems for electric cars．"

2．In New York，students at 18schools participate in a program called We Future Cycle．Started by Anna Giordano in 2014，it teaches kids to recycle，compost （制成堆肥），and reduce  food waste．
Lunch areas at the participating schools are equipped with three clearly marked bins-compost，recycle and share．While the first two are common in schools，the third is rare，where kids can put their unwanted drinks，fruits，and even untouched sandwiches．Items in the  container are available for any student that wants them．Whatever remains at the end of the day is donated to the food bank．Giordano says the three bins have helped reduce the nun of trash bags from an average of 22to just 2!
To ensure kids adopt similar habits at home，the non-profit has created extensive   curriculum to educate families  about the importance of sorting waste into the proper streams of recycling，composting，trash and food to donate-They also urge parents to have  conversations with their kids about food choices．
But，as  we're all aware，kids aren't   only ones that Waste food-adults are  epually bad，if not worse!To prevent that，Josh Treuhaft  founded Salvage Supperclub in 2014．The occasionally organized dinners promise people  a tasty multi-course meal for a mere 550USD   perperson．It is also a plan to savewaste because the delicious food is made from vegetables   that are past their prime and，therefore，headed for the trash bin．
The other catch？Customers have to eat their  meals inside a dumpster（大型垃圾装卸车）!The place，of course，is totally clean．It is just a symbolic gesture．In addition to helping people rethink their actions，Treuhaft also helps them to do good by donating part of the profits to non-profits devoted to fighting against food waste．
32．What is mainly talked about in the text？C
A．The importance of saving food．

34．What do we know about We Future Cycle？C
A．It has a very long history．
B．It donates its profits to schools．
C．It educates parents as well as children．
D．It occasionally provides people with free dinner．

20．Though"nanometer"（纳米） is now a fashionable term all over the world，few people know exactly what it is．It has become a new favorite of manufacturers and sellers in recent years．Many"high-tech"products bearing the name"nano"have entered the market，bringing more mysterious feeling to surprised consumers．
Nanometer is a very small length unit of measure，and is very small．One millimeter is 1000micrometers，and one micrometer is 1000nanometers．That is，one nanometer is one billionth of a meter．Nano materials are solid materials composed of particles（粒子） or crystallites（晶体） of less than 100nanometer in size．Then，is a cup made of nano material really any different from an ordinary cup in function as far as how it works？
Are nano cups really so wonderful？A reporter went to the Institute of Nanomedicine，which is the first such institute of such a sort in the world and the only one in China，specializing in researching the investigation of the application of nano technology into medicine．
A water molecule（分子） is composed of 2hydrogen atoms and 1oxygen atom．It can be changed only by special working skillfully of the atoms．The material making up the cup can have nanometer particles．But it cannot change the chemical and physical propertiesof the water contained in it．The water in the cup is still water．When people drink it，it will produce no special effect on human body．
Professor Ji who worked in the Instiute of Nanomedicine told the reporter，so far，the investigation of nano materials is still limited in the laboratory．No commercial micro products can be produced yet．With the present level of science and technology，the time of everyday goods made of nanometer materials is still years away．
The products labeled with nano marks in the market now are only traditional products coated with a thin layer of nanometer material，which makes them more abrasion resistant（耐磨），much easier to be cleaned，or oil resisting or moth proof（防蛀）．
Professor Ji explained that nano cup is a real cup．It can also be included in the list of nano products in a certain sense．But the nano cup has not changed its property and function as a cup．It is not a magical medicine for curing and health care．

67．Which of the following shows the right relationship？A
A．nanometer＜micrometer＜millimeter＜meter
B．micrometer＜millimeter＜nanometer＜meter
C．nanometer＜millimeter＜micrometer＜meter
D．millimeter＜micrometer＜nanometer＜meter
68．It can be inferred from the passage thatD．
A．real nano products are being produced by some companies
B．nano materials have been put into use in daily goods
C．the nano cup is very effective in curing and health care
D．real nano products haven't become available for people
69．The underlined word"properties"in the fourth paragraph probably meansC．
A．possessions   B．reactions   C．qualities D．symbols
70．What would be the best title for the passage？B
A．High-tech Products        B．Nano Materials
C．High-teach Research       D．Nano Cups．

7．Most American schools have boys and gifts in the same classroom．But a public high school in the small，rural town of Boonsboro，Maryland，offers a special program called the Academy．Top students in the ninth and tenth grades can attend single-sex classes for math，science，English and social studies．
The aim is to help teenagers keep their mind on their work by keeping males and females apart．What they really want to do is take that top group of kids and take them to the very highest level they can achieve there，so that they're prepared for college．
Students are invited to enter this program after they finish middle school，and placement in the Academy is voluntary．However，they need high marks and test scores and strong teacher recommendations．They also need to be involved m activities．
Almost 350students have taken part in the Academy．It began as an experiment in 2010．
Michael Bair has been at Boonsboro High for twenty years and directs the Academy．His ninth-grade English class for boys centers on books that he believes boys find interesting．He says that the novels the students are reading now are very manly （男子气概的） novels．These novels deal with the arrogance （傲慢） of man and the pride of man which finally leads to man's downfall．
One of those books，for example，is The Call of the Wild by Jack London．This classic story tells of a dog stolen from his home and sold to work as a sled dog in Canada's Klondike Gold Rush．
Morgan Fleet，a senior at Boonsboro High，likes being in the Academy．She says boys and girls act differently when they are together in a classroom．She believes this difference seems to prevent her from developing herself because she's more focused on thoughts like"Oh，I wish they would shut up．Oh，what do they think of me？''instead of focusing on"What's the homework？What's going on in this class？What's the lesson？"．
There is one activity that girls and boys in the Academy do together．At the end of the day，many of them stay and help tutor students who are having trouble in school．

17．Beijing had its biggest snowfall since 1951．Britain is suffering through its longest cold snap （寒潮） since 1981．And freezing weather is hitting the Deep South，including Florida's orange groves and beaches．
    Whatever happened to global warming？
    Such weather doesn't seem to fit with warnings from scientists that the Earth is warming because of greenhouse gases．But experts say the cold snap doesn't contradict global warming at all-it's just a temporary phenomenon in the long-term heating trend．"It's part of natural variability，"said Gerald Meehl，a senior scientist．With global warming，he said，"we'll still have record cold temperatures．We'll just have fewer of them．"
    Scientists say man-made climate change does have the potential to cause more frequent and more severe weather extremes．But experts did not connect the current cold snap to climate change．
    So what is going on？
"We basically have seen just a big outbreak of Arctic air over populated areas of the Northern Hemisphere"，Arndt said．
In the atmosphere，large rivers of air travel roughly west to east around the globe between the Arctic and the tropics．This air flow acts like a fence to keep Arctic air restricted．But recently，this air flow has become bent into a zigzag （之字形） pattern，wandering north and south．If you live in a place where it brings air up from the south，you get warm weather．In fact，record highs were reported this week in Washington state and Alaska．
But in the eastern United States，like some other unlucky parts of the globe，Arctic air is coming from the north．And that's how you get a temperature of 3 degrees in Beijing，a reading of minus-42 in mainland Norway，and 18 inches of snow in parts of Britain．The zigzag pattern arises naturally from time to time，but it is not clear why it's so strong right now．
71．What is the best title of the text？D
A．Freezing weather is hitting the Deep South．
B．We'll still have record cold temperatures．
C．The air flow has become a zigzag pattern．
D．Cold snap doesn't contradict global warming．
72．With global warming，we willA．
A．also meet with severe cold snap
B．have more hot temperatures forever
C．never experience cold temperatures
D．have more cold temperatures
73．According to experts，the current cold snapB．
A．suggests that the climate has changed greatly
B．is not related to the climate change
C．shows that the climate will turn cold
D．is affected by global warming
74．Beijing had its biggest snowfall since 1951 because ofC．
A．a fence from the Arctic
B．a cooling trend in climate
C．a big outbreak of Arctic air
D．its large population
75．We can conclude thatA．
A．not all the parts of the Northern Hemisphere are cold in face of the cold snap
B．the zigzag pattern arises naturally accidentally
C．Beijing will get cold weather next year
D．Washington state and Alaska will not face cold weather next year．

4．I told my friend Graham that I often cycle the two miles from my house to the town centre but unfortunately there is a big hill on the route．He replied，"You mean fortunately．"He explained that I should be glad of the extra exercise that the hill provided．
My attitude to the hill has now changed．I used to complain as I approached it but now I tell myself the following； This hill will exercise my heart and lungs．It will help me to lose weight and get fit．It will mean that I live longer．This hill is my friend．Finally as I wend my way up the incline I comfort myself with the thought of all those silly people who pay money to go to a gym and sit on stationery exercise bicycles when I can get the same value for free．I have a smug smile of satisfaction as I reach the top of the hill．
Problems are there to be faced and overcome． We cannot achieve anything with an easy life，Helen Keller was the first deaf and blind person to gain a University degree．  Her activism and writing proved inspirational．She wrote，"Character cannot be developed in ease and quiet．Only through experiences of trial and suffering can the soul be strengthened，vision cleared，ambition inspired and success achieved．"
One of the main determinants of success in life is our attitude towards adversity．From time to time，we all face hardships，problems，accidents，and difficulties．Some are of our making but many confront us through no fault of our own．While we cannot choose the adversity we can choose our attitude towards it．
Douglas Bader was 21when in 1931he had both legs cut off following a flying accident．He was determined to fly again and went on to become one of the leading flying experts in the Battle of Britain with 22aerial victories over the Germans．He was an inspiration to others during the war．He said，"Don't listen to anyone who tells you that you can't do this or that．That's nonsense．Make up your mind，you'11never use crutches or a stick，then have a go at everything．Go to school，join in all the games you can．Go anywhere you want to．But never，never let them persuade you that things are too difficult or impossible．"
The biographies of great people are filled with examples of how they took kinds of steps to overcome the difficulties they faced．The common thread is that they did not become defeatist or depressed．They chose their attitude．They chose to be positive．They took on the challenge．They won．
