                                              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.                        
1. Which of the following can warn you against the unsecure network?  
A. Android.  
B. V.P.N.  
C. Lookout.   
D. Find My iPhone.
2. By using V.P.N., users can _______.  
A. find their lost phone on the Internet
B. erase all the data from the phone remotely
C. check their bank balance now and then
D. save their browsing from being tracked    
3. The underlined word "that" in Para. 6 refers to the fact that _____. 
A. a V.P.N. app kicks in automatically
B. the user starts V.P.N. apps manually
C. the app takes a while to connect
D. users spend no time thinking about it

第二部分  阅读理解(共25小题;第一节每小题 2 分,第二节每小题1分;满分45分)

第一节 阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项,并在答题卡上将该项涂黑。

A

Diane Arbus is known for creating intense black and white photographs of very unusual people. She used a special camera that produced square shaped images. One art expert said Diane Arbus turned photography inside out. Instead of looking at her subjects, she made them look at her.

Diane Arbus was born in 1923 to a wealthy family in New York City. After finishing high school at the age of 18, Diane married Allan Arbus. Mr. Arbus worked in the advertising department of her father’s store.

It was Mr. Arbus who gave Diane her first camera. Diane soon decided to take a class with the famous photographer Berenice Abbott. The Arbuses eventually started taking photographs of clothing. These images were used as advertisements for Diane’s father’s store. After the birth of their daughter, Doon, the Arbuses started a business together. Their purpose was to photograph clothing fashions. Diane Arbus was the stylist. She would prepare the hair and faces of the fashion models who wore the clothing being photographed. Allan Arbus took the pictures.

The couple soon had jobs from important fashion magazines such as “Vogue” and “Harper’s Bazaar”. Their work was very successful during the 1950s. They became part of a group of artists that were helping to redefine visual culture. They were breaking with past traditions to create a new look for a new decade, the sixties.

But Diane was not satisfied with her secondary role. She wanted a more active part in making photographs. She wanted to explore her own artistic expression and freedom. To do this, she stopped working with her husband. Then she started taking photography classes at the New School in New York City.

Arbus’ teacher, Lisette Model, influenced her in many ways. She showed Diane how to use a camera like an expert. She also taught Diane to use her art to face her doubts and fears. Miss Model once said that Diane soon started “not listening to me but suddenly listening to herself.”

41. Diane Arbus got her first camera ______.

IV.阅读理解(共17小题;每小题2分,满分34分)

Like cats, geckos(壁虎)always land on their feet. If they happen to fall from a wall or leaf they’ve been climbing, a quick move of the tail makes sure that they always land on their feet first, a new study finds.

Geckos are truly built for climbing: their feet have hairy toes that can fix themselves to a wall or other vertical(竖直的)surfaces. However, geckos’ feet can’t always keep hold and they may fall to the ground. When geckos fall or jump off a wall, they always land stomach-side down. Geckos’ long tails become necessary during their falls, the new study shows.

Researchers did an experiment. They placed geckos up-side-down on the underside of a leaf. When they lost their foothold and fell, the geckos pitched (倾斜)their tails for balance. They then rotated(旋转)their tails to make their bodies rotate. As soon as they were right-side up, they stopped rotating. On average, it only took the geckos about a tenth of a second to right themselves so that they would land on their feet.

Cats use a different way to land on their feet after a fall. As their tails don’t have the power like geckos’ tails, cats can’t use them to right themselves. Instead they twist their bodies around mid-air.

Engineers are trying to build a robot that imitates the geckos’ climbing ability. A tail will be fixed to the robot to allow it to keep balance.

54. What do we know about geckos?

A. Their toes make it possible for them to walk on walls.

B. Their tails can fix them to a wall or other vertical surfaces.

C. They often land on their backs when they jump off walls.

D. It takes them a second to right themselves in mid-air.

55. How do cats avoid their injury during a fall?

A. By twisting their bodies.                 B. By fixing their toes to the ground.

C. By using their tails to right themselves.        D. By landing upside-down.

56. Geckos’ special abilities have given engineers some new ideas to _________.

A. allow robots to climb vertical surfaces       

B. reproduce geckos like robots

C. invent robots that can rotate on the ground

D. invent robots that can balance themselves using their tails

57. What is the text mainly talking about?

A. The interesting living habits of geckos.   B. The differences between cats and geckos.

C. Why geckos always land on their feet.      D. How geckos climb up vertical walls.

A

Molly Wilson had been a dancer and a mother for many years when she decided to sail round the world to raise money for charity.

As a child she had trained as a ballet dancer, but at l5 she had grown too tall for classical ballet, so she became a member of a pop dance team.

She got married, and after she had children she retired from show business to bring them up. They grew up, and when they were 18 they left home.

She says, “When I decided to do the round-the-world race, my husband thought I was bored because the children had left home. He was also worried because I had never sailed before. I was not bored, but I had met some people who told me about the race. They had taken part in it, but they had only done one section, say, from New Zealand to Australia. I wanted to do the whole ten-month journey. ”

Before Molly left she did a lot of training, but it hadn’t prepared her for the worst weather which they experienced. By the end of October last year, she had raised more than $50,000 for charity.

She says, “Sometimes I ask myself, what did I do? How did I do it? But then I think, it’s the same as being a dancer. Before I left on trip, I had trained hard. I had got very fit and had prepared myself completely. Then on the trip I was simply a good team member.”

Ⅳ.阅读理解(30分)

Everyone knows that the French are romantic, the Italians are fashionable and the Germans are serious. Are these just stereotypes(陈规) or is there really such a thing as national character? And if there is, can it affect how a nation succeeds or fails?

At least one group of people is certain that it can. A recent survey of the top 500 entrepreneurs(实业家) in the UK found that 70 percent felt that their efforts were not appreciated by the British public. Britain is hostile to success, they said. It has a culture of jealousy(嫉妒). As a result, the survey said, entrepreneurs were “unloved, unwanted and misunderstood”. Jealousy is sometimes known as the “green-eyed monster(怪物)” and the UK is its home. Scientists at Warwich University in the UK recently tested this idea. They gathered a group of people and gave each an imaginary amount of money. Some were given a little, others a great deal. Those given a little money were given the chance to destroy the large amounts of money given to others—but at the cost of losing their own. Two thirds of the people tested agreed to do this.

This seems to prove the entrepreneurs were right to complain. But there is also conflicting evidence. The Organization for Econnomic Cooperation and Development(OECD) recently reported that the UK was now the world’s fourth largest economy. That is not bad for people who are supposed to hate success. People in the UK also work longer hours than anyone else in Europe. So the British people are not lazy, either.

“It’s not really success that the British dislike,” says Carey Cooper, a Professor of management at the University of Manchester Institute of Science and Technology. “It’s people using their success in a way that seems arrogant(傲慢) or unfair or which separates them from their roots.”

Perhaps it is the entrepreneurs who are the problem. They set out to do things in their way. They work long hours. By their own efforts they become millionaires. But instead of being happy they complain that nobody loves them. If they were more friendly, people would like them more. And more people want to be like them.

56. What does the underlined word “it” in the second paragraph refer to?

A. One group of people.            B. A great survey.

C. National character.              D. A nation.

57. Most of the British top entrepreneurs surveyed believe that ________.

A. they are not popular simply because they are successful

B. the British public are hardworking

C. love of success is Britain’s national character

D. they are considered as “green-eyed monsters”

58. What does the result of the Warwich University test show?

A. Two thirds of the people tested didn’t love money.

B. Most people would rather fail than see others succeed.

C. An imaginary amount of money does not attract people.

D. Most people are willing to enjoy success with others.

59. The writer of the passage seems to suggest that _______.

A. jealousy is Britain’s national character

B. British entrepreneurs are not fairly treated

C. the scientists at Warwich University did a successful test

D. the British dislike the entrepreneurs because they do not behave properly
