4．Google Glass，a wearable computer，will not go on sale for many months．But the resistance is already under way．The glasses-like device，which allows users to access the Internet，take photos and shoot videos，has been banned by a bar in Seattle，because according to the bar'owner，the bar was"kind of a private place．"Besides，large parts of Las Vegas will not welcome wearers．
Google Glass is a pair of glasses with a tiny computer attached to the right earpiece and has the ability to capture any chance encounter and broadcast it to millions．As personal technology becomes increasingly invisible，it is causing questions of whether it will rob people of privacy．
As Google sees it，Glass is a revolutionary new way to quickly and effortlessly connect people with information．Google stresses that Glass is a work in its early stage，with test versions now being released to 2，000developers．The company hopes they'll be seen as normal and become accepted in the same way smart phones are．The wearer has to speak or touch the device to activate（激活） it，and must look directly at someone to take a photograph or video of them．"We are thinking very carefully about how we design Glass because new technology always raises new issues，"said Courtney Hohne，a Google spokeswoman．
Critics view Glass as an unfriendly new technology that could rob people of what few privacy they have left．They think Google is downplaying the privacy and security risks．According to Google，it's obvious when someone is taking pictures or recording a video on Glass．Developers，however，are pushing the limits．One created a small sensation in tech circles with a program that eliminated the need for gestures or voice commands．To snap a picture，all the user needed to do was wink（眨眼）．
Imagine a surveillance（监控） device that you could wear on your body all day without anyone being the wiser．Out on the street，in the subway，at a bar or cafe，people would never know whether the stranger next to them is secretly recording their every move．It is really a privacy disaster．

2．I remember my mother as a strong woman．She came to America when she was 12-old enough to remember her language，she achieved scores and grades high enough to be admitted to Duke University．With a degree in computer science，she finally became the manager of a company in New York．My mother could give fluent speeches，say"wolves"correctly．
It was my mother who always stressed the importance of language．From the time I was born，I was read to．I would fall asleep to the sounds of my parents'voices，whether it was my dad's softly accented，or my mother's clear English．The flow of language was unbroken，and whether in Chinese or English，the stream of communication flowed through our house．
One October morning in sixth grade，after my mother had left to catch the train to the city，I left the house for the bus stop．I was surprised when I saw our car，the door hanging open．As I drew closer，I saw my mother lying on the ground．
In the hospital，it was hard to believe that the lady who lay before me was my mom．My mother could not remember my name．As the leaves changed colors，it became clear that the stroke had created a wall between my mother's mind and mouth：her mind was not any less clear，but the words she spoke were not what she meant．
The battle my mother faced taught me the importance of language．Without it，identity does not exist； relationships cannot be formed； stories cannot be told； directions cannot be given，and knowing anything about anyone is impossible．Without language，communication cannot take place．Without language，one cannot express the beauty of a sunset or the kindness of a stranger．The world would pass us by in silence．

41．From where might the author's mom come to AmericaA？

1．When a magazine for high school students asked its readers what life would be like in twenty years，they said：Machines would be run by solar power．Buildings would rotate（旋转）so they could follow the sun to take maximum advantage of its light and heat．Walls would"give light"and"change color with the push of a button．"Food would be replaced by pills．School would be taught by electrical impulse（电脉冲）while we sleep．Cars would have radar（雷达）．Does this sound like the year 2000？Actually，this article was written in 1958and the question was，"what will life be like in 1978？
The future is much too important to simply guess about，the way the high school students did，so experts are regularly asked to predict accuately．By carefully studying the present，skilled businessmen，scientists，and politicians are supposedly able to figure out in advance what will happen．But can they？One expert on Cities wrote：Cities of the future would not be crowded，but would have space for farms and fields．People would travel to work in"airbuses"，large all-weather helicopters carrying up to 200passengers．When a person left the airbus station he could drive a coin-operated car equipped with radar．The radar equipment of cars would make traffic accidents"almost unheard of"．Does that sound familiar？If the expert had been accurate it would，because he was writing in 1957．His subject was"The city of 1982"．
If the professionals sometimes sound like high school students，it's probably because future study is still a new field．But economic forecasting，or predicting what the economy will do，has been around for a long time．It should be accuate，and generally it is．But there have been some big mistakes in the field，too．In early 1929，most forecasters saw an excellent future for the stock market．In October of that year，the stock market had its worst losses ever，ruining thousands of investors who had put their faith in financial foreseers．
One forecaster knew that predictions about the future would always be subject to significant error．In 1957，H．J．Rand of the Rad corporation was asked about the year 2000，"Only one thing is certain，"he answered．"Children born today will have reached the age of 43．"

C．experts are always better than others in figuring out what the future will be like
D．forecasting the future is not an easy job even for experts in this field

A．economy forecasting is rather a new field
B．experts began economy forecasting in 1929
C．the predictions about economic situation caused the investors to lose lots of money

18．Leading experts on the Internet，technology and policy have shared the same opinion on what we can expect in the next decade when it comes to connectivity and its effects on society．
The Pew Research report asked thousands of experts and members of the public for opinions on"the most significant overall influences of our uses of the Internet on humanity"---and some had a rosier outlook than others．
"The smartest person in the world nowadays could well be stuck behind a plough in India or China，"said Hal，Google's chief economist．"Enabling that person----and the millions like him or her---will have a strong effect on the development of the human race．"
Early Internet pioneer David Hughes agreed："When every person on this planet can communicate two-way with every other person on this planet，the power of nation-states to control every human inside its geographic boundaries may start to disappear．"
Wearables （electronic equipment that people can wear ） could monitor more than just steps，predicted UC Berkeley's Aron Roberts---or do more than just monitor："We may literally be able to adjust both medications and lifestyle changes on a day-by-day basis or even an hour-by-hour basis．"
Microsoft Reaearch's Jonathan Grudin is more pessimistic（悲观）："By making so much activity visible，it exposes the gap between the way people behave and the way we think they ought to behave．Adjusting to this will be an unending，difficult task．
And the difference between the rich and the poor will have a new aspect："Only the well-off （and well-educated） will know how to preserve their privacy，"warned one expert．
"Will the Internet make it possible for our entire civilization to fall down together，in one big awful step？Possibly，"admitted Harvard"s Doctor Searls．："But the Internet has already made it possible for us to use one of our unique advantages----the ability to share knowledge---to a degree higher than ever before．"

36．As for the influences of our uses of the Internet on humanity，some of the experts areB．
A．Realistic
B．Optimistic
C．Doubtful
D．Careful
37．According to Hal，in the future，those who will influence the development of human race areB．
A．Google's economists
B．Chinese and Indian
C．The educated persons
D．World leading experts
38．People will be able to change their lifestyles at any time according toD．
A．The development of communication skills
B．The suggestions made by computer experts
C．The prediction made by the home computers

B．The way we thought they ought to behave
C．The way people really behave in life

C．Knowledge and civilization of human beings．
D．Possibilities of the Internet for the future users．
17．People are being lured （引诱） onto Facebook with the promise of a fun，free service without realizing they're paying for it by giving up large amounts of personal information．Facebook then attempts to make money by selling their data to advertisers that want to send targeted messages．
Most Facebook users don't realize this is happening．Even if they know what the company is up to，they still have no idea what they're paying for Facebook because people don't really know what their personal data is worth．
The biggest problem，however，is that the company keeps changing the rules．Early on，you keep everything private．That was the great thing about facebook-you could create your own little private network．Last year，the company changed its privacy rules so that many things-your city，your photo，your friends'names-were set，by default （默认） to be shared with everyone on the Internet．
According to Facebook's vice-president Elliot Schrage，the company is simply making changes to improve its service，and if people don't share information，they have a"less satisfying experience"．
Some critics think this is more about Facebook looking to make more money．Its original business model，which involved selling ads and putting them at the side of the page，totally failed．Who wants to look at ads when they're online connecting with their friends？
The privacy issue has already landed Facebook in hot water in Washington．In April，Senator Charles Schumer called on Facebook to change its privacy policy．He also urged the Federal Trade Commission to set guidelines for social-networking sites．"I think the senator rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them，"Schrage admits．
I suspect that whatever Facebook has done so far to invade our privacy is only the beginning，which is why I'm considering deactivating（撤销） my account．Facebook is a handy site，but I'm upset by the idea that my information is in the hands of people I don't know．That's too high a price to pay．

31．What do we learn about Facebook from the first paragraph？C
A．It is a website that sends messages to targeted users．
B．It makes money by putting on advertisements．
C．It profits by selling its users'personal data．
D．It provides loads of information to its users．
32．What does the author say about most Facebook users？B
A．They are reluctant to give up their personal information．
B．They don't know their personal data enriches Facebook．
C．They don't identify themselves when using the website．
D．They care very little about their personal information．
33．Why does Facebook make changes to its rules according to Elliot Schrage？A
A．To provide better service to its users．
B．To follow the Federal guidelines．
C．To improve its users'connectivity．
D．To expand its scope of business．
34．What does Senator Charles Schumer advocate？C
A．Setting guidelines for advertising on websites．
B．Banning the sharing of users'personal information．
C．Formulating regulations for social-networking sites．
D．Removing ads from all social-networking sites．
35．Why does the author plan to cancel his Facebook account？C

16．California has a new program called the Digital Textbook Initiative．"Starting this fall with high school math and science，we will be the first state in the nation to provide schools with a state-approved list of digital textbooks．"That was Governor Arnold Schwarzenegger in June，talking about his effort to get schools to use materials available free online．He listed reasons why he thinks digital textbooks make sense．
California approves traditional textbooks in six-year cycles．Digital ones can offer the latest information．They lighten the load of school bags．They save paper and trees，and make learning more fun and interactive．And above all，he said，they help schools with their finances．
The state has had to make severe cuts in school spending because of deep financial problems．More than six million students attend California public schools．
Earlier this year，California invited content developers to offer digital math and science materials for high schools．These had to meet at least 90% of the state's learning requirements．Specially trained teachers examined 16 textbooks and approved ten of them．Six of the ten were published by the CK 12 Foundation，a nonprofit group that had been developing digital science and math books for about two years．The foundation paid teachers and other education professionals to write and edit them．The money came from a group financed by the Khosla Family．
California cannot require schools to use the digital textbooks．Individual school districts will have to decide for themselves．Susan Martimo，a California Department of Education official，says she does not expect widespread use right away．Her best guess is that some schools with a lot of technology will be the first to use them，but only in addition to their traditional books．
School administrators point out that the texts may be free online，but students need a way to access them．Not everyone has a computer or electronic reader．Schools could print out copies，but that would not help the environment．Also，there is the cost to train teachers to use digital textbooks effectively．

36．The Digital Textbook InitiativeD．
A．will probably take effect in six years
B．covers all the high school subjects
C．has been approved by all states
D．is advocated by California state governor
37．Digital textbooks are most meaningful in that they are toA．
A．help save money                  
B．benefit the environment
C．provide interesting materials    
D．reduce students'heavy burden
38．Which of the following is TRUE of the CK 12 Foundation？D
A．It publishes all the books for students free of charge                   
B．It provides money to write and edit all the textbooks in the USA
C．It is organized and supported by Khosla Family                   
D．It offers digital math and science materials for high schools
39．According to Susan Martimo，digital textbooks willC．
A．come into fashion from now on
B．soon replace traditional ones
C．first be adopted by well-equipped schools
D．surely be approved by school districts
40．It can be inferred from the last paragraph thatB．
A．schools are reluctant to print out copies
B．the program is not easy to carry out
C．students have no access to the computers
D．teachers fail to use the textbooks effectively．
15．One butterfly species has come back from near extinction （灭绝）and is beginning to quickly adapt to warmer weather，a new research has found．
The research，presented at the Butterfly Conservation's international conference，found that the quino checkerspot butterfly has both moved to higher，cooler altitudes and has chosen an entirely new plant on which to lay its eggs．The butterfly，once thickly settled in Mexico and California，has witnessed a sharp drop in its numbers as climate change sees temperatures in their natural habitats（栖息地）become too hot and dry for the food plant its babies eat．
Camille Parmesan，professor at Plymouth University said that while the butterfly's movement is encouraging，it also points to the need for habitat protection．If the butterflies-and potentially other species-adapt quickly enough to move to higher altitudes，it's required that healthy environments exist in those altitudes in which the butterflies can settle．It's also required that these species have corridors（走廊）by which to move to higher altitudes，so that they can avoid getting killed by roads or long stretches of developed land．
Scientists believe the quino checkerspot is the first butterfly species to change habitat and diet so quickly，but it's not the only species to be forced to adapt to climate change．A 2013 study found that，while trees aren't moving northward as quickly as scientists expected，they're instead speeding up their lifecycles，causing younger trees to replace older trees at a higher rate．Certain desert plants，on the other hand，have migrated（迁徙）surprisingly far upslope，with some moving more than 800 feet from their 1963 lowermost boundaries．
Other species aren't adapting so quickly，however．The migration patterns of many butterfly species are being changed by earlier and warmer springs-something that's happening to some bird species as well．This changed migration timing could lead to mismatches in food and weather conditions for the migrating species，with food sources that were traditionally obtainable at a migration destination hatching or blooming（开花） too early for the birds or butterflies to consume．
