[Q]: Article: Security--for the information on your smart phone, as well as for the phone itself--is a hot topic these days.The truth is that you're packing a lot of sensitive information on your phone, and you should keep it safe. When it comes to physical security, iPhone users would do well to download Find My iPhone, a free app from Apple that allows you to visit a website and see your (lost, stolen or misplaced) phone on the map.You can then sound an alarm, send a message that will pop up on its screen, lock the phone or erase all your data. Android does not have an exact equivalent , but there are plenty of alternatives. A free app called Lookout offers the findmyphone feature.The paid version allows you to wipe the data from your phone remotely. Then there is your coffee shop's WiFi network.Anyone with minimal technical expert skill can snoop on people using shared wireless networks, harvesting passwords and other personal data. Lookout will caution you when you've logged on to an insecure network, but cannot protect you once you're there. In order to protect yourself on such networks, you can use a virtual private network, or VPN. This turns all your activity into nonsense to anyone trying to read along with you from across Starbucks. It also keeps websites from tracking you and, if you're travelling, allows you to get access to sites that may be blocked in other countries. If you have an iPhone, the simplest VPN app is probably Hotspot Shield, whose distinguishing feature is said to be that it automatically kicks in each time you start browsing , as opposed to other VPN apps that require you to start them up manually .This matters, because even if you decide you want a VPN app, you want to spend approximately zero time thinking about it. For the most part, _ was true of Hotspot Shield, though occasionally it took a while to connect or temporarily lost connection without warning. I found myself having to turn the app on and off sometimes, which involved setting my phone constantly. If even reading about the settings on your phone drive you crazy, then it is probably best to stay away from a VPN app. But if you're the type who can't resist checking your bank balance from your corner bar, the hassle may be preferable to the risk.
Answer: Find My iPhone.
[A]: Which of the following can warn you against the insecure network?

[Q]: Article: Many Chinese parents think as long as the child is watched by people, there is no danger. But from the start, when the child is born, he needs to communicate with others, especially the communication with parents. Many children in our country are growing up in the environment which lacks a sense of security and love. They want to get back the love lost in childhood but never catch it. On the one hand, Chinese like saving faces; on the other hand, they want to encourage their children to be aspirants . They often say how hard somebody else is studying, how good their grades are, and what prize they get. This comparison is the worst thing especially when they say it before many people. Each time you compare your children to others, you will only bring them much disappointment and pain. Parents should knock at the door when they go into the room of their children. They should get permission before they move something of their children. Parents should first communicate with their children and consider their decisions. Parents should respect their children, and consider them as adults. This respect should begin from changing diapers. Before changing diapers for the children, parents should tell them. Children who do not be respected also do not know how to respect others. Many parents have high hopes for their children, and force them to the way that they think is right, even if the kids do not fit, or do not like, such as playing the piano or going abroad. Under this kind of pressure, children become unhappy and the quality time becomes a struggling period. When children recall their childhood, all memories are unhappy, which is indeed the failure of some parents.
Answer: Parents mustn't enter the room if not permitted.
[A]: Which of the following probably makes the child disappointed?

[Q]: Article: When Lady Gaga releases a new, pleasing and easily remembered single, it quickly goes around the world. Now scientists have discovered the same thing happens with the songs of another creature----the humpback whale. The mammals become absorbed by new tunes just like people do, and the most popular original whale songs spread globally like hit singles. Male humpback whales are famed for the loud, long and complicated songs they make during the mating season. Each song lasts for 10 to 20 minutes and the males can sing nonstop for 24 hours. At any one time, all the males in a population sing the same song. But a study shows that this song changes over time and spreads around the oceans. Dr. Ellen Garland of Queensland University, said: "Songs move like cultural communication from one population to another, causing all males to change their song to a new version." Researchers recorded songs from six neighboring populations of whales in the Pacific over a decade. They found that new versions of the songs appear over time and always spread from west to east. It takes two years for songs that appear in the waters off Australia to be heard in French Polynesia. Most of the new songs contain material from the previous year mixed with something new. " It would be like getting an old Beatles song together with U2," she said. " Occasionally they completely throw the current song out of the window and start singing a completely new song". Dr. Garland believes that a small number of whales may migrate to other populations carrying the new songs with them, or that they are heard by passing whales. The researchers suspect whales adopt new songs to make themselves distinct. Dr. Garland said: " we think this male search for new songs is in the hope of being that little bit different and perhaps more attractive to the opposite sex."
Answer: The songs of humpback whales can spread globally.
