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 we live in a world where you simply cannot keep a secret.

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(收费站) 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(优惠券). 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.

Can trees talk? Yes — but not in words. Scientists have reason to believe that trees do

communicate with each other. Not long ago, researchers learned some surprising things. First a willow tree attacked in the woods by caterpillars（毛毛虫）changed the chemistry of its leaves and made them taste so terrible that they got tired of the leaves and stopped eating them. Then even more astonishing, the tree sent out a special vapor—a signal causing its neighbors to change the chemistry of their own leaves and make them less tasty.

   Communication, of course, does not need to be in words. We can talk each other by smiling, raising our shoulders and moving our hands. We know that birds and animals use a whole vocabulary of songs, sounds, and movements. Bees dance their signals, flying in certain patterns that tell other bees where to find nectar for honey. So why shouldn’t trees have ways of sending messages?

1．It can be inferred from the passage that caterpillars do not feed on leaves that          .

A．have an unpleasant taste

B．are lying on the ground

C．have an unfamiliar shape

D．bees don’t like

2．According to the passage, the willow tree was able to communicate with each other by       .

A．waving its branches              B．giving off a special vapor

C．dropping its leaves               D．changing the color of its trunk

3．According to the passage, bees communicate by        .

A．touching one another             B．smiling one another

C．making special movement         D．making unusual sound

4．The author believes that the incident described in the passage         .

A．cannot be taken seriously          B．seems completely reasonable

C．should no longer be permitted      D．must be checked more thorough

Can we turn negative thoughts like “I never do anything right” into positive ones like “I can succeed”? Is there power in positive thinking?
Researchers in Canada just published a study in the journal Psychological Science that says trying to get people to think more positively can actually have the opposite effect: it can simply emphasize how unhappy they are．
The study’s authors, Joanne Wood and John Lee of the University of Waterloo and Elaine Perunovic of the University of New Brunswick, begin by referring to older research showing that when people get feedback which they believe is overly positive, they actually feel worse, not better．If you tell your friend that he may be an Einstein, you’re just underlining his faults．In one 1990s experiment, a team including psychologist Joel Cooper of Princeton asked participants to write passages opposing funding for the disabled．When they were later praised for their sympathy, they felt even worse about what they had written．
In this experiment, Wood, Lee and Perunovic measured 68 students’ self-esteem（自尊）．The participants were then asked to write down their thoughts and feelings for four minutes．Every 15 seconds, one group of students heard a bell．When it rang, they were supposed to tell themselves, “I am lovable．”
Those with low self-esteem didn’t feel better after the experiment．In fact, their moods turned significantly darker than those of members of the control group, who weren’t urged to think positive thoughts．
The paper provides support for newer forms of psychotherapy（心理治疗） that urge people to accept their negative thoughts and feelings rather than fight them．In the fighting, we not only often fail but can make things worse．Meditation（静思） techniques, on the contrary, can teach people to put their shortcomings into a large, more realistic perspective（视野）．Call it the power of negative thinking．

Can feeling of nostalgia(怀旧) be good for you? Or is it unhealthy to have a strong love for the past?
For years, medical experts have studied nostalgia and the reasons for it. Many experts warn that too much nostalgia is harmful. They say living in the past shows that a person is unhappy with his present life. These feelings keep the person from living his life to its fullest.
　　However, experts say it is normal to love the past sometimes. In fact, a little nostalgia can enrich a person’s life.
　　Dr. Louise Kaplan has written several books about nostalgia. She says these feelings often begin when a young person is between 13 and 19 years old.
　　“This is the time when you must face the loss of your childhood, “Kaplan says. “You see your new life is easily destroyed. But you think romantically about a golden past. You remember your childhood as a time when life is perfect.”
　　These feelings continue as the person gets older, Kaplan adds. She says many grown persons have a hard time keeping up with changes in the modem world, so they think back to their younger years. At that time the world seemed simple and more harmless.
　　Kaplan says these feelings do not always actually exist. The good old days did not always exist. The good old days weren’t always good. However, she says nostalgia can be helpful, if used properly.
　　“Feelings of nostalgia can cause you to remember a time when you had high hopes and dreams, “Kaplan says. “It might give you the strong wish to catch those dreams today in your past life.” She adds that nostalgia can prevent you from “cutting yourself off from your aim”.
