Q: Read the article and select the best answer. Article: Can you imagine a stranger will read your e-mails without your permission or scan the website you've visited or perhaps someone will casually glance through your credit card purchases or cell phones bills? All of the things may happen to you one day. In fact, it's likely that some of these things have already happened to you. Who would watch you without your permission? It might be a spouse, a girlfriend, a marketing company, a boss, a cop or a criminal. Whoever it is, they will see you in a way you never intended to be seen or even do something that may bring a disaster to you. Psychologists tell us boundaries are healthy, and that it's important to reveal to friends, family and lovers at appropriate times. But few boundaries remain nowadays. The digital bread crumbs you leave everywhere make it easy for strangers to know who you are, where you are and what you like. In some cases, a simple Google search can leak the deepest thought in your mind. Like it or not, increasingly _ The key question is: Does that matter? For many Americans, the answer apparently is "No". When opinion polls ask Americans about privacy, most of them say they are really concerned about losing it. And 60 percent of the respondents say they feel their privacy is "slipping away, and that bothers me". But people say one thing and do another. Only a small of Americans change any behaviors in an effort to preserve their privacy. Few people turn down a discount at tollbooths to avoid using the EZ-Pass system that track automobile movements. Privacy economist Acquisti has run a series of tests that reveal people will give up personal information such as telephone number, address, or social security numbers just to get their hands on a pitiful 50-cent-off coupon . But privacy does matter--at least sometimes. It's like health; when you have it, you don't notice it. Only when it's gone do you wish you'd done more to protect it. Without privacy, one will be naked in front of others. Question: What would psychologists advise on the relationships between friends? Options: A: Friends should open their hearts to each other. B: Friends should always be faithful to each other. C: There should be a distance even between friends. D: There should be fewer quarrels between friends.
A: C

Q: Read the article and select the best answer. Article: On a cool summer night in Wyoming, Dean Biggins waits patiently in his truck. Suddenly, Biggins, a wildlife biologist, spots a pair of eyes in the distance. Baggins can't believe his luck: He's just caught sight of a black-footed ferret --one of the world's rarest animals. Just over a century ago, hundreds of thousands of black-footed ferrets lived on the grasslands in North America known as the prairie. But the animals died off as prairie dog disappeared. Black-footed ferret depend on prairie dogs for both food and shelter. After a ferret has eaten a prairie dog, it moves into the animal's burrow . When cattlemen started setting up ranches on the prairie in the early 1900s, they thought prairie dogs, which eat grass, might compete with their cattle and sheep for food. To make sure that didn't happen, they killed off billions of prairie dogs. As prairie dog populations dropped, black-footed ferrets disappeared. By 1979, researchers couldn't find any ferrets and declared the species extinct. Then, two years later, a small group was discovered. Although scientists were excited about the discovery, it soon became clear that the ferrets were in danger. A disease called sylvatic plague was killing the ferrets. Soon, just 18 ferrets remained. "To help the species survive, the researchers put all the ferrets in cages in 1986 and began raising them," says Randy Matchett, a wildlife biologist. To help the black-footed ferrets learn survival skills, wildlife biologists put them through a process called preconditioning. Researchers build a fence around old prairie dog burrows and put the ferrets in them when they are a couple of months old. While the animals get used to their new home, researchers feed them live prairie dogs so they can practice hunting. "Now about 1,000 black-footed ferrets are back in the wild. Despite their amazing comeback, black-footed ferrets aren't out of the woods yet," says Matchett. Sylvatic plague is still a threat, and ranchers still don't want too many prairie dogs on their land. "We... Question: Black-footed ferrets once became extinct mainly because _ . Options: A: they lacked food B: they were overhunted C: a disease attacked them D: their habitat was destroyed
A: A

Q: Read the article and select the best answer. Article: People say time is .But to what.I do know that sometimes time"seems"to be moving slower.Remember Christmas Eve when you were a child? It was the longest night of the year.It lasted forever! And now it seems like I just paid my bill yesterday...and it's due again! People tell me all too frequently...I need more time! Oh ,really?...Mother Teresa, Michelangelo,and Helen Keller all had 24 hours a day.Look what they did with their time! Is it that we need to manage our time better...or our priorities ?You've heard the expression"first things first."The first step in understanding the power of time is to understand that it is limited.Why is it then that some people get a lot more done? We know the answer.They use their time smartly. One day an expert on time management was speaking to a group of students and announced a quiz.He pulls out a wide-mouthed jar.Next,he places about a dozen fist-sized rocks,one at a time , into the jat, until no more will fit."Is it full?"he asks."Yes,"responds the class."Oh really?"he asks.So he takes out a bucket of gravel . which he manages to work down into the spaces between the larger rocks."Is it full now?"he asks. Wising up,one answered,''Probably not."Sure enough. he takes out a bucket of sand,which he pours into the empty spaces."Is it full now?"he asks."N0 1"reply the students confidently.So he takes a glass of water and fills it in.Then he asks,"What is my point?'' One said,''No matter how full your schedule is,if you try really hard,you can always fit some more things into it!" "No,"the speaker replied,"It tells us if you don't put the big rocks in first, you'll never get them in at all.'' What are the big rocks? The things you should put in to your jar first. The rich don't get 25 hours and the poor don't get 23...we all get the same.Let's use them wisely! Invest your time wisely! Question: The text is written mainly _ Options: A: to explain the origin of the expression"first things first" B: to call on us to use our time in a smart manner C: to introduce a meaningful class given by an expert D: to tell us about the relativity and the power of time
A: B
