It’s parents’ worst nightmare. Their child doesn’t come home one evening and is missing for several days.
When a 14-year-old boy from Atlanta, Georgia disappeared earlier this year, his mother turned to her Smartphone for clues using an app（应用程序） called Family Tracker that helped track his location.
“You can see where your loved ones are without having to call or bother them. ”said Roberto Franceschetti of LogSat, the creators of the Family Tracker, which has more than 100,000 users and is available worldwide.
Parents can track the location of their child on a map, send messages, and even sound an alarm on the phone in a long distance.
“We have an option for the sender to make a very unpleasant, noisy sound. It’s a loud alarm and we repeat that sound every two minutes until the person picks it up, ”he said.
Parents don’t need to own a Smartphone to track their children. The service is also accessible through the web, as long as the phone that is being tracked is running the app.
Family Tracker has an additional service that keeps records of all data from the app for a two-week period, which the company calls GPS breadcrumbs.
“With a subscription（预定）, we keep all the locations where people have been on our servers. You can see where your kid has been for the past two weeks. You can find out where someone was at a certain time or when that person was at a specific place, ”Franceschetti explained.
“When somebody gets abducted（劫持）, usually whoever does this throws the phone away or takes the battery out. We were hoping that our app would at least provide information on where the person was abducted or where they had been in the past. ”
But will these types of apps let out personal secrets?
“The advantages are huge compared to the disadvantages. Let’s not forget that the person always has to give initial permission—no one can be tracked unless they allow someone to do it. ”said Franceschetti.

查看习题详情和答案>>The new iPhone 3G should please everyone. Its look and feel are only slightly improved, but a faster network loads Web pages more quickly, true GPS functionality allows it to easily find places nearby, and the new $199 price (down from $400) makes it an affordable luxury.
Before deciding whether to buy, however, make sure you can actually take advantage of the iPhone 3G's high-speed data network. 3G stands for third-generation, which in non-geek speak translates to Web pages and mail messages that, ideally, load about three times faster than on the original iPhone. Even better, 3G coverage enables you to make a phone call and surf the Web at the same time. That's great, if you live or work in a place where the 3G network of AT&T（美国电话电报公司） (the sole wireless carrier of the iPhone) is active. That's not so great in cities like New York where AT&T's cellular coverage is awful. As one of my colleagues in New York City, who bought the original iPhone, commented, "It's just a toy. You can't make phone calls on it, so I carry my Verizon phone with me all the time."
The real fun begins when you tap on the icon called "App Store" and start browsing the hundreds of add-on applications that have been developed just for the iPhone. You'll find tons of games (I like JirboBreak, a free game inspired by the Atari classic Breakout) and mobile versions of popular websites like Pandora, Facebook, MySpace and the New York Times. Most apps will cost you, but the vast majority are $9.99 or less. The apps work on the old iPhones too, but you'll enjoy them a lot more on the iPhone 3G because many of the programs, including Yelp (local business reviews), Whrrl (mobile social networking) and UrbanSpoon (restaurant reviews), use your exact location — provided by the iPhone 3G's GPS chip — to make recommendations. The apps also load much faster over the 3G network.
The new iPhone 3G has following features except that _______
A. It looks and feels better B. It has a faster network
C. It is easy to locate a place D. It is too expensive for people to buy
Why do one of my colleagues carry Verizon phone with him all the time? ______.
A. Because iPhone 3G is just a toy.
B. ecause he prefers Verizon phone better.
C. Because AT&T's cellular coverage is terrible there
D. Because Verizon phone enables him make a phone call and surf the Web at the same time

查看习题详情和答案>>The United Nations is warning that the world is not prepared to deal with the fast growth of cities. The World Economic and Social Survey 2013 calls for new ways to meet the needs of city populations. More than 6.5 billion people are expected to be living in cities by 2050.
Most new city dwellers will be in developing countries. The United Nations says the effect on limited resources in many countries will be huge. The World Economic and Social Survey points to the increasing demand for energy, water, sanitation, public services, education and health care.
The world population is expected to rise to more than nine billion by 2050, two-thirds of all people are expected to live in cities. The United Nations says about 80 percent of this growing urban population will be found in Africa and Asia.
The report says sustainable development of urban areas requires coordination and investments to deal with important issues, these include land-use, food security, job creation and transportation.
Willem Van Der Geest is with the United Nations Department of Economic and Social Affairs, he says cities need to work closely with rural communities, so that food supplies can be secured, and the environment can be protected.
"We need enough integration(整合，融合) with cities... An integration between the rural and urban economies is absolutely vital for issues of nutrition, food security, and environmental sustainability."
The report says development in a sustainable（可持续发展）way is important to end poverty. The report also examines the problem of food insecurity, which affects hundreds of millions of people around the world. One in eight people still severely lack nutrition.
UN officials say some things are clear. The Assistant Secretary-General for Economic Development, Shamshad Akhtar, says world food production will have to increase by 70%, that increase will be needed to feed the additional 2.3 billion people expected on the planet by the middle of the century. She says an important part of meeting that need is to waste less food. "There has to be efforts to reduce food wastage. ."
