What's safer? Using a numeric PIN code(数字密码)to unlock your smartphone or relying on a swipe(滑动)pattern? New research suggests that, at least when someone close by could be looking over your shoulder, you might be safer with an old-fashioned PIN.
The research by the United States Naval Academy and the University of Maryland tested what could best secure smartphones from so-called "shoulder surfing attacks". So, if you are worried about someone looking over your shoulder while you unlock your phone, would you be wiser to use a PIN or a pattern? According to this research at least, the answer to that question is pretty clear.
Those who have a single observation of your screen as you unlock it with a swipe pattern will be successful in knowing it 64.2% of the time. Security can be improved somewhat by removing lines on the pattern lock (35.3% success rate for shoulder surfers).
By comparison, the use of a six-digit PIN greatly reduces the chances for an attacker to determine how to unlock your smartphone, with just 10.8% of attacks being successful. In tests, viewers were able to determine the users' lock-screen patterns from up to six feet away, from a variety of different angles, even after a single viewing.
Indeed, when it comes to safety, past research has determined that an unlock pattern is about the same as a three-digit PIN -something I hope that none of us would rely upon.
The researchers' conclusion is that a PIN of six digits or more is the most secure de fence against shoulder surfing attacks, and while both types of pattern lock are poor, patterns without lines provide greater security.
Unsurprisingly, the research confirmed that phones with larger screens were found to provide less security against shoulder surfing attacks.

When it comes to medical care, many patients and doctors believe "more is better." But what they do not realize is that overtreatment-too many scans, too many blood tests, too many procedures-may bring harm. Sometimes a test leads you down a path to more and more testing, some of which may be attacking, or to treatment for things that should be left out.
Terrence Power, for example, complained that after his wife learned she had Wegener's disease, an uncommon disorder of the immune system(免疫系统), they found it difficult to refuse testing recommended by her doctor. The doctor insisted on office visits every three weeks, even when she was feeling well. He frequently ordered blood tests and X-rays, and repeatedly referred her to experts for even minor complaints. Even when tests came back negative, more were ordered, and she was hospitalized as prevention when she caught a cold. She had as many as 25 doctor visits during one six-month period. The couple was spending about $30,000 a year for her care.
After several years of physical suffering and near financial ruin from the medical costs, the couple began questioning the treatment after discussing with other patients in online support groups. "It's a really hard thing to determine when doctors have crossed the line," Mr. Power said. "You think she's getting the best care in the world, but after a while you start to wonder: What is the purpose?" Mr. Power then spoke with his own primary care doctor, who advised him to find a new expert to oversee Mrs. Power's care. Under the new doctor's care, the regular testing stopped and Mrs. Power's condition was stable. Now she sees the doctor only four or five times a year.

A.She had to be hospitalized for three weeks whenever she had a cold.
B.Her doctor asked her to consult other experts for her complaints.
C.When test results showed she was fine, her doctor still ordered more tests.
D.She did not have any insurance, so she became penniless.
2.When did the Powers start to doubt the treatment of Mrs. Power?
A.After they knew about the treatment of other patients.
B.After they analyzed the results of her blood tests
C.After Mrs power was cured of her illness.

4.What is the main idea of this passage?
A.Treatments do not always cause harmful side effects.
B.Patients tend to believe more testing is better treatment.
C.Doctors generally recommend office visits that are necessary.
D.Too much medical care may not be beneficial to patients.
I've often wondered if I might do more good as a travel agent rather than as a psychologist. It seems that I have been more dramatically affected by certain kinds of travel experiences than I ever have.
My trip to Iceland is a fine example of that. The plan was to spend two days in a remote mountain hut(棚屋)in Iceland. I was working on a photographic book about winter in Iceland and needed to capture images of this amazing region of high mountain peaks, smoky volcanoes, and lakes with floating icebergs.
The moment after we arrived, the weather turned extreme making visibility impossible. It snowed so much and the wind blew so hard that we couldn't leave the tiny hut. To stay warm, we walked around in circles much of the day inside the tiny hut. We tried to call for help but the radio did not work. Day after day, we watched our supplies of food and fuel grow dangerously short. We got acute cabin fever(幽居病)and started going for walks and ski expeditions outside. Even when the weather finally broke, nobody came to get us even though it was three days beyond our scheduled pickup. By the time the rescue team came to pull us out, we had all given up hope.
From then on, the world looks different to me, as does my life. It would have taken me years of psychotherapy(心理治疗)to get to the same point.
Almost everyone has a story to tell, and interestingly, most of these experiences were not altogether pleasant at the time. In fact, it appears that the most constructive life-changing journeys were those that involved some sorts of awful and uncomfortable events that forced the person to develop new resources, increase confidence, and solve problems in new ways.
