A smart phone’s low battery warning is the only warning that most people take seriously. Try the following steps and you will improve your battery life.
1. Let there be less light
For larger smart phones, the longer the screen is on and the brighter it is, the faster you
r battery goes. Try making the screen as dark as you can bear it and still read a text. Darkening the screen is common among teenagers, but it may be hard for Mom and Dad to see what’s showing on their phone.
2. Turn off the signals
Your smart phone does a lot of communicating in the background. They’re checking for things like new emails, text messages, Wi-Fi signals, Bluetooth signals, your location and more. These activities do drain your battery life, so you should turn off whatever you aren’t using. Location Services is also another feature that burns up your battery, so you can use 
GPS and Wi-Fi to find out which apps have access to Location Services and turn them off.
3. Turn off notifications (通告)
Another way to improve battery life is to stop the constant flow of notifications and updates from Facebook, email, games and sites. Your phone will automatically pick up these notifications when it’s connected to the Internet, and they can have a noticeable impact on battery life.
4. Use battery saving mode (模式)
For a quick way to improve your battery, simply put your smart phone in Airplane Mode. If Airplane Mode is too limiting, some phones have a specific battery saver mode. This shuts down unimportant functions and apps like Wi-Fi, some updates and more.
If used properly, these tips above will improve your battery life up to 30 percent.
1.The underlined word “drain” means “ ”.
A. light up B. use up
C. pick up D. make up
2.If you want to improve your battery life, you are advised to use a .
A. small screen B. large screen
C. bright screen D. round screen
3.We can infer that aged people tend to .
A. email family members B. use Location Services
C. darken the screen D. brighten the screen
4.We can learn that Airplane Mode can .
A. improve signals B. waste energy
C. affect health D. save power

With smart phones taking the world by Storm，a phone that Can only send and receive voice
calls and text messages may seem like a relic from a bygone age．Yet in East Africa，simple
phones like these are changing the face of the economy，thanks to the mobile money services that are spreading across the region．
Usilng the text-messaging function built into the GSM system(全球通)used by most cell
phone networks，these services allow people without a bank account or credit card to use their
phone as an electronic walletthat can be used to store．send or receive cash．
It works like this：you pay cash to your local agent who then tops up your mobile money
account using a secure form of text messaging．That money can be transferred(转账)to another
person by sending a message to their cell phone account．
For some the system is a lifeline．“If I didn,t have my mobile phone．1 would be very
poor，”says Neyasse Neemur，a mother of four children who lives in northern Kenya．“Now I
can sell fish．”
Neemur took up fishing in July last year，but making money from it was a little tricky，
especially as Turkana people do not usually eat fish．A truck from Ethiopia to Tanzania passes
through her village once a week，and she arranged to have the driver transport the fish several
hundred kilometres south to market in Kisumu．where relatives sell the fish．
“I get the money transfer immediately．”says Neemur．“Then I can pay for my children to go to school and for vegetables and beans，”she adds，“so I don’t need to eat fish．”
According to the Central Bank of Kenya，payments worth around l billion Kenyan shillings
($13 million)per day were transferred through Kenya,s mobile money systems in 2009，equalling
the country,s credit card transactions(业务)．The bank expects mobile money transfers to overtake credit cards in 2010．
49．In Paragraph l，the author uses“simple phones”to________.
A．make a comparison B．introduce a topic
C．describe a scene D．offer an argument
50．What can we learn about the simple phones in East Africa?

D．They can do nothing except send and receive calls or messages．
51．The word“it”in the third paragraph refers to_______.
A．the GSM system B．the mobile money service
C．the credit card service D．the cell phone networks
52．The story of Neyasse Neemur suggests that_______.
A．the mobile money service plays a key rote in the locals, life

A new study’s findings warn that smart phones are seriously messing with your quality of life.
The study looked at the responses of 256 smart phone users. Researchers found that 13 percent of participants were addicted to their smart phones, spending 3.6 hours per day on the devices. Social networking sites were the No. 1 time wasters with 87 percent of users, while instant messaging apps at 52 percent and news apps at 51 percent.
Almost 25 percent of the people admitted that their smart phones caused “communication issues” in their real lives, including less conversation with family and friends. What’s worse, the majority of users said “their smart phone use caused distraction(精神不集中) from many aspects of their lives, including employment, hobbies and studies.”
“People need to know the potential addictive properties( 性质) of mobile phones,” a researcher said. “There should be a warning before people purchase them or before they download an app. If you’re downloading a game, there should be a warning saying that you could end up playing this for hours and you have other responsibilities that could be ignored.”

A new phone app uses vibrations from smart phones to warn people about earthquakes.
The phone app _______ sudden shaking of the earth’s surface through sensors in smart phones. It is called MyShake. It is the work of four researchers at the University of California, Berkeley. They said they created a worldwide warning system that would _______ people and give them time to prepare. The MyShake app is _______ only for Android phones.
Smart phones are _______ accelerometers (加速度感应器). These instruments measure movement, like that of a car or airplane. MyShake uses phone accelerometers to measure seismic (地震的) activity. It has been _______ to know the difference between normal activity and earthquake movement. The software developers say their app is right 93 percent of the time.
A smart phone sends seismic information to the app developers. If the developers receive several notifications _______, it recognizes that an earthquake might be taking place or will take place soon.
Using information sent from the app, the network then _______ the location and strength of the quake in real time. MyShake can record magnitude 5.0 earthquakes at distances of 10 kilometers or less.
MyShake uses very _______ power, according to its developers. Only when seismic activity is _______ by the app does it become active and sends data to the network. The app works best when your phone is resting on a ________ surface, like a table.
The developers hope that MyShake can add to information collected by the U.S. Geological Survey. That U.S. agency has created the Earthquake Early Warning System, also ________ EEW. The EEW has deployed (部署) sensors for measuring quakes in many areas.
In places where no such equipment ________, MyShake may be the only method of early quake ________. The app also shows ways to stay safer during an earthquake. The developers say it will become more effective as more people use it.
“Our goal is to build a worldwide seismic network and use the data to________ the effects of earthquakes on us as individuals and on society as a whole,” say the researchers.
The developers say they hope to add a feature that would ________ people about a possible tsunami: a huge wave after an earthquake.

One of the things that makes your smart-phone so smart is that if you pull it out in the sun, it senses that—and dials up the screen brightness to compensate. But it’s not a perfect solution.
“First of all, it’s still not bright enough—you have to remember how respectable sunlight is.” Shin-Tson Wu, a physicist at the University of Central Florida. The other problem, he says of the brightened screen, is it kills the battery. So Wu and colleagues have produced a battery-sparing alternative: an anti-reflective screen-coating. Based on the eyes of moths. “Nature is so rich! We can learn a lot from nature. “The thing Wu and others have learned about moth eyes, is that they’re uneven, dotted with tiny projections. That uneven surface reduces the reflection of light off their eyes- thought to help the bugs escape predators (捕食者), and see better in low light. So Wu and his team built a similar surface with tiny dimples (凹), to cut down on glare. He says the dimpled coating could improve the readability of a screen by five to 10 times, compared to a normal smart-phone screen. The details are in the journal Optica.
The tech hasn’t been commercialized yet, and that could take a few years. Which gives researchers time to take advantage of another property of these surfaces: they’re flexible. Meaning the possibility of bendable displays. Combine that with the bendy batteries we reported on in a recent podcast(播客), and it looks the smart-phones of the future could be set for a real transformation.
1.Why do the researchers develop the anti-reflective screen-coating?
A.To brighten the screen. B.To make profits.
C.To take in the sunlight. D.To save the use of battery.
2.What inspired the invention of the screen?
A.The predators. B.The reflection of light.
C.The eyes of moths. D.The smooth surface.
3.How does the screen work?
A.It helps bugs escape.
B.It slows down reading.
C.The smooth surface protects our eyes.
D.The rough surface decreases the reflection of light.
4.What do the researchers expect of the screen?
A.I’ll transform itself. B.I’ll be environment-friendly.
C.I’ll reach consumers soon. D.I’ll be powered by recyclable batteries.

Like many other people, I love my smart phone, which keeps me connected with the larger world that can go anywhere with me. I also love my laptop, because it holds all of my writing and thoughts. In spite of this love of technology, I know that there are times when I need to move away from these devices and truly communicate with others.
On occasion, I teach a course called History Matters for a group of higher education managers. My goals for the class include a full discussion of historical themes and ideas. Because I want students to thoroughly study the materials and exchange their ideas with each other in the classroom, I have a rule ---no laptop, iPads, phones, etc. When students were told my rule in advance of the class, some of them were not happy.
Most students assume that my reasons for this rule include unpleasant experiences in the past with students misusing technology. There's a bit of truth to that. Some students assume that I am anti-technology. There' s no truth in that at all. I love technology and try to keep up with it, so I carelate to my students.
The real reason why I ask students to leave technology at the door is that I think there are very few places in which we can have deep conversions and truly engage complex ideas. Interruptions by technology often break concentration and allow for too much dependence on outside information for ideas. I want students to dig deep within themselves for inspiration and ideas. I want them to push each other to think differently and make connections between the course materials and the class discussion.
I’ve been teaching my history class in this way for many years and the evaluations reflect students' satisfaction with the environment that I create. Students realize that with deep conversation and challenge, they learn at a level that helps them keep the course materials beyond the classroom.
I'm not saying that I won't ever change my mind about technology use in my history class, but until I hear a really good reason for the change, I'm sticking to my plan. A few hours of technology-free dialogue is just too sweet to give up.
1.Which of the following statements is true?
A. The author's history class received low assessment.
B. The students think highly of the author's history class.
C. The author made the rule in that he was against technology.
D. The author made the rule mainly because of his unpleasant experiences.
2.According to the author, the use of technology in the classroom may .
A. allow students to get on well with each other
B. improve teaching and offer more help
C. prohibit students being involved in class
D. help students to better understand complex themes
3.What can we infer from the passage?
A. More and more students will be absent in history class.
B. The author will carry on the success in the future
C. Some students will be punished according to the rule.
D. The author will help students concentrate on what they learn.
