Smartphone Security Blankets
Security—for the information on your smartphone, 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 (application program) from Apple that allows you to visit a website and see your (lost, stolen or misplaced) phone on a 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 find-my-phone 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（窥视）people using shared wireless networks, harvesting passwords and other personal data. Lookout’s apps will caution you when you’ve logged on to an unsecure 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 V.P.N. This turns all your activity into nonsense to anyone trying to read along with you from across the Starbucks. It also keeps websites from tracking you and, if you’re traveling, allows you to get access to sites that may be blocked in other countries.
If you have an iPhone, the simplest V.P.N. app is probably Hotspot Shield, whose distinguishing feature is said to be that it automatically kicks in each time you start browsing (浏 览), as opposed to other V.P.N. apps that require you to start them up manually. This matters, because even if you decide you want a V.P.N. app, you want to spend approximately zero time thinking about it. For the most part, that 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 drives you crazy, then it is probably best to stay away from a V.P.N. 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.

Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body.
Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes(酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs.
Processed foods contain chemical elements, which might confuse the appetite mechanism that tells us when we’ve had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body’s cells. The body’s metabolism (新陈代谢) becomes inactive, and the result is weight gain and obesity.
The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become

more common.
To stop this vicious circle in its tracks, people need to consume food and supplements that will neutralize the acid already accumulated in body. Eating the right types of raw and whole foods can help. It’s also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself, you need to take an active approach.
42. It can be inferred from Para. 2 that . A. foods with natural enzymes help people keep fit B. we’d better be cautious about raw and whole foods C. it is essential for people to protect their vital organs D. giving up cooked and refined foods is a new lifestyle 43. Processed foods are unhealthy because they A. destroy body’s cells C. are difficult to digest
. B. may lead to obesity D. stop body’s metabolism.
44. What is the main purpose of this passage?
A. To warn people of the problem of obesity. B. To advocate eating more raw and whole foods. C. To inform people of the harm of processed foods. D. To tell the differences between raw and processed foods. 45. What is likely to be talked about following the last paragraph?
A. Different causes of acid accumulation. C. Suitable types of raw and whole foods.
B. Correct ways to cook raw foods. D. Active approaches to avoid acid.

If you have ever been in a school play or even made believe you were a doctor, detective, or a space traveler, you know the enjoyment that acting brings. Almost all of us have the wish to play the part of someone—or something—else. 46 In the ancient world, acting was often associated with religious ceremonies and other special occasions. As far back as 2200 B.C. trained Chinese actors performed ceremonial dances in costume and makeup at harvest festivals. 47 To the dance was gradually added

pantomime—the imitation of movements and gestures—as well as the wearing of masks, the singing of chants, and finally the use of dialogue.
While acting was coming into its own in the ancient Chinese classical theatre, it was doing the same in the western world, in Greece. From about 500 B.C. on, acting became a highly specialized art in Greece. Greek actors, however, still wore masks, and their motions were largely fixed by custom. 48 Modern acting, by contrast, gives the individual actor great opportunity to develop his or her personal talents for serious, comic, or musical drama. The names, faces, and styles of famous movie actors are known worldwide. 49 A special form of acting takes place in radio drama, which was highly popular before television. In radio drama the actors face an unique challenge. They are unseen by their audience. So they must rely on voice alone to make their characters real to the listeners.
50 Only forty percent of Broadway actors are employed, most of them for only part of the year. Those who become stars need not only talent, but determination. They must not be easily discouraged. Otherwise, they might give up before the opportunity for stardom presents itself.
A. The origins of acting are in the act of remembering. B. Drama in Greece began with festivals honoring Dionysus.
C. It is believed that this was the first step in the development of acting. D. Historical records indicate that this desire is as old as civilization itself. E. Acting is not, as many people think, a quick, easy road to fame and riches.
F. Broadway and television provide other stages on which actors can display their talent. G. Consequently, they had little opportunity to demonstrate their individual personalities.
