I grew to be a tall girl but I tried to be as ordinary as possible. At school, I always chose a seat in the back of the room, and never raised my hand in class. When I was 16, I went to my new school. And I liked the English teacher. In my last year in high school, however, we were told that a new English teacher, Oliver Bascom, was going to teach us.

    Oliver Bascom! The girls laughed as we imagined a short and bald（秃头的）man．The situation was not funny, because this man would teach us for the whole year. Surprisingly, after we opened the door, there in front of the blackboard, we saw a young and handsome man!

    What followed was chaos, seventeen-year-old girls flying to get to seats in the front of the room. And I managed to get a front and center desk.

    I really wanted to make a good impression on my new teacher, but I usually kept quiet. The day that directions were given for our first major writing assignment, I arrived late to class. A friend later gave me the guidelines and I thought I understood them. I worked the whole weekend on the essay and waited nervously for Mr. Bascom's evaluation.

After three days, he arrived in class holding the corrected papers. "I've chosen the ten best essays for class discussion." he said.

    Twenty minutes later, my heart sank when he got to the last essay, and I didn't hear my name.

"These are all great essays," Mr. Bascom continued. "However, I am now going to read you the most successful of all…" We were all surprised as I was the author of this unusual work. A different girl walked out of the classroom that day. I knew that I had a new set of standards to live up to and that anything was possible in the future. Finally, I raised my head.

    Skeptics are a strange lot. Some of them refuse to admit the serious threat of human activities to the environment, and they are tired of people who disagree with them. Those people, say skeptics, spread nothing but bad news about the environment. The “eco-guilt” brought on by the discouraging news about our planet gives rise to the popularity of skeptics as people search for more comforting worldviews.

    Perhaps that explains why a new book by Bjorn Lomborg received so much popularity. That book, The Skeptic Environmentalist, declares that it measures the “real state of the world” as fine. Of course, another explanation is the deep pockets of some big businesses with special interests. Indeed, Mr. Lomborg's views are similar to those of some Industry-funded organizations, which start huge activities through the media to confuse the public about issues like global warming.

    So it was strange to see Mr. Lomborg's book go largely unchallenged in the media though his beliefs were contrary to most scientific opinions. One national newspaper in Canada ran a number of articles and reviews full of words of praise, even with the conclusion that “After Lomborg, the environmental movement will begin to die down.”

    Such one-sided views should have immediately been challenged. But only a different review appeared in Nature, a respected science magazine with specific readership. The review remarked that Mr. Lomborg's “preference for unexamined materials is incredible(不可信的)”.

    A critical (批判的)eye is valuable, and the media should present information in such a way that could allow people to make informed decisions. Unfortunately, that is often inaccessible as blocked by the desire to be shocking or to defend some special interests. People might become half-blinded before a world partially exhibited by the media. That's a shame, because matters concerning the health of the planet are far too important to be treated lightly.

    Confident, smart and high-tech, they're followers of pop culture and know what social networking is all about. They're tweens, children between the ages of 10 and 12. These young people are no longer little kids but they are not yet teenagers, because tweens are in a state of transition (转变).

    The tween years are hard for children. From a social point of view, tweens are dealing with quite a lot. They have to face changing relationships, middle school and a whole lot of pressure (压力) to succeed and fit in. They may become angry over seemingly small things. A bad test grade, an argument with a friend, a bad day on the ball field, or a request to clean a bedroom might set them off.

    Elizabeth Hartley-Brewer, a parenting expert in London and author of Talking to Tweens, says, "The tween years are when young people begin to realize the wider world and to see themselves as separate from their families."

    Right now, tweens' friends are everything to them. It's universal for the age, but they show it in different ways. For boys, the whole friendship thing is through technology and sports. Girls like to talk.

    Tweens are also a hot market. What do tweens consider cool? Music is at the top of the cool list, followed by going to the movies. "Being smart" comes third, tied with video games, followed by electronics, sports, fashion and protecting the environment, according to a report.

    Undoubtedly, tweens have great spending power in the United States. It was the tween market that made Justin Bieber and Harry Potter household names. Retailers(零售商) know tweens are a hot market for clothes, music and entertainment. Tweens have their own sense of fashion and enjoy their own parts of popular culture.

    Scientists recently discovered that pictures on cave walls at Creswell Crags are the oldest known in Great Britain. But they didn't find out in the usual way.

    Archaeologists often date cave art with a process called radiocarbon dating. The technique can measure the age of carbon found in charcoal (木炭) drawings or painted pictures. Carbon is an element found in many things, including charcoal and even people. But in this case, there was no paint or charcoal to test. People carved the pictures of animals and figures into the rock using stone tools. The scientists had an "aha!" moment when they noticed small rocks stuck to the top of the drawings. The small rocks must have formed after the drawings were made.

    "It is rare to be able to scientifically date rock art," said Alistair Pike, an archaeological scientist at Britain's University of Bristol. "We were very fortunate that some of the engravings were covered by stalagmites(石笋).

    When a test proved that the stalagmites formed 12,800 years ago, the scientists knew the art underneath them had to be at least that old. And some of the animals shown, like the European bison, are now extinct-another tip-off that the art is quite old.

    The artists came to Creswell Crags, This place is one of the farthest points north reached by our ancient ancestors during the Ice Age. At that time, much of the North Sea was dry, so people could move about more easily.

    Some tools and bones found there are 13,000 to 15,000 years old. They show that the travelers hunted horses, reindeer, and arctic hare. Their artwork is similar to art in France and Germany. It tells scientists that the Creswell Crags artists must have had a close connection to peoples several thousand kilometers away—another important clue to understanding how humans spread out across the world.

    Compulsive（强迫的）shoppers may have a new psychological excuse to blame for their wild shopping. Psychologists at the University of Canterbury in New Zealand are studying the "shop-till-you-drop" habit as a behavioral disorder similar to compulsive eating. Compulsive shoppers frequently buy more than they can afford or more than they need, and it causes them distress.

    "It becomes a problem when you are out of control," psychology lecturer Neville Blampied said. "When you are feeling bad and blue, what do you do? Some people eat chocolate cake and ice cream. Some people take the credit card and go out to the shop." Bank managers understand the problem because they have to deal with people who have to be persuaded to stop using their cards drawing money.

    Compulsive shopping was first discovered in 1915, although it was then known as oniomania. Few studies have been done on the problem.

    An advertisement in a Christchurch paper, calling for people to take part in an experimental treatment program designed by Mr Wilson, attracted 10 replies. But the problem, said Mr Wilson, is"clearly not rare". He thinks that compulsive shopping should be treated with drugs." As psychologists we are interested in non-drug treatments for behavioral difficulties," Mr Wilson said.

    Compulsive eaters or shoppers get a kick from their habit. "Both activities provide an immediate kind of kick and you feel a bit better," he said. "You have long-term problems, but human beings are extremely good at not seeing long-term problems and are very sensitive to short-term benefits," he said.

    The aim of the treatment was to help people find better ways of managing their emotions. The program, consisting of 10 one-hour weekly lessons and two follow-up treatments, is loosely based on teaching stress management.

    "You often have to start to get people to correctly recognize their emotions. Not being able to know what you really feel weakens your ability to solve the problems connected with what's making you feel that way," Mr Wilson said.
