Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?
UBC Professor Simard explains how trees are much more complex than most of us ever imagined. Although Charles Darwin thought that trees are competing for survival of the fittest, Simard shows just how wrong he was. In fact, the opposite is true: trees survive through their co-operation and support, passing around necessary nutrition "depending on who needs it".
Nitrogen (氮) and carbon are shared through miles of underground fungi (真菌)
networks, making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons (神经元) in our brains, and when one tree is destroyed, it affects all.
Simard talks about "mother trees", usually the largest and oldest plants on which all other trees depend. She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow. When humans cut down "mother trees" with no awareness of these highly complex "tree societies" or the networks on which they feed, we are reducing the chances of survival for the entire forest.
"We didn't take any notice of it" Simard says sadly. "Dying trees move nutrition into the young trees before dying, but we never give them chance." If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.

(Q = Question; A = Answer)
Situation I
Q: If someone sits right next to me in an empty movie theater, is it rude to move?
A: Maybe, but nobody will fault you for it. Chances are that close sitter doesn't realize he disturbs you, so he may miss your annoyance. You undoubtedly aren't the first person he's met who needs enough room. Forgive his bad judgment, move quietly and enjoy the show.
Situation II
Q: If I use the bathroom at a store, do I need to buy something?
A: Consider frequency and urgency. Is this a one-time or an emergency? If so, you don't have to buy anything, but it would be kind if you did. However, if you regularly use the bathroom at this place, then you are a customer, and you should act like one.
Situation III
Q: If someone is talking loudly on the bus, is there a nice way to ask him to keep it down?
A: No. Try other means.1) Stare at him until he gets aware of it and quiets down. 2) Lift your finger in a silence motion(动作)and smile. 3) Put on earphones and ignore him.
Situation IV
Q: If I remember my friend's birthday a day late, should I apologize or just wish her a happy birthday like nothing happened?
A: This is the reason why the word belated was invented. "Happy belated birthday!" is short for: "Well, I know I forgot, but then I remembered. Forgive me and happy birthday."
Situation V
Q: Can I lie about seeing a text because I was too busy or lazy to respond(回复) to it?
A: Don't lie. Receiving a text does not mean you need to respond to it. Why waste a perfectly good lie when the truth will serve? "Yes," you can say if ever asked, "I saw it." No explanation is needed as to why you don't respond.

A new study shows students who write notes by hand during lectures perform better on exams than those who use laptops(笔记本电脑).
Students are increasingly using laptops for note-taking because of speed and legibility(清晰度).But the research has found laptop users are less able to remember and apply the concepts they have been taught.
Researchers performed experiments that aimed to find out whether using a laptop increased the tendency to make notes "mindlessly" by taking down word for word what the professors said
In the first experiment, students were given either a laptop or pen and paper .They listened to the same lectures and were told to use their usual note-taking skills. Thirty minutes after the talk , they were examined on their ability to remember facts and on how well they understood concepts.
The researchers found that laptop users took twice as many notes as those who wrote by hand. However, the typists performed worse at remembering and applying the concepts. Both groups scored similarly when it came to memorizing facts.
The researchers' report said, "While more notes are beneficial, if the notes are taken mindlessly, as is more likely the case on a laptop, the benefit disappears."
In another experiment aimed at testing long-term memory, students took notes as before but were tested a week after the lecture. This time, the students who wrote notes by hand performed significantly better on the exam.
These two experiments suggest that handwritten notes are not only better for immediate learning and understanding, but that they also lead to superior revision in the future.
1.More and more students favor laptops for note-taking because they can .
A. write more notes B. digest concepts better
C. get higher scores D. understand lectures better
2.While taking notes, laptop users tend to be .
A. skillful B. mindless
C. thoughtful D. tireless
3.The author of the passage aims to .
A. examine the importance of long-term memory
B. stress the benefit of taking notes by hand
C. explain the process of taking notes
D. promote the use of laptops
4.The passage is likely to appear in .
A. a newspaper advertisement B. a computer textbook
C. a science magazine D. a finance report

As has been all too apparent in recent days at Balcombe, few issues cause greater concern than energy policy. Many village communities feel their countryside is being ruined by the power-producing machines of wind farms; yet they never take "direct action", even though the planning laws put them at a severe disadvantage. And the generous subsidies (财政补贴) , which encourage the expansion of wind power, are not favorable to the village communities and set landowners in conflict with other residents (居民) .
Those who disagree with the rapid expansion of wind farms state that the damage they cause is out of proportion(比例) to the benefits they bring, because their energy output cannot match that of the carbon-based power stations they are supposed to replace. Supporters insist that wind must be part of a mix of renewables, nuclear and carbon, and that the country is committed to meeting EU ( European Union) targets for non-carbon energy generation. ZXXK
Against this background, the fact that there is an argument within the Government over whether to publish an official report on wind farms' impact on the countryside becomes even more extraordinary. The two parties in the coalition (联合) government are in disagreement over what it should say.
We have some advice for the two parties: publish the report, and let the country be the judge. Even if it contains evidence that wind farms are harmful, it will hardly be a pleasant surprise to people who do not like them. Equally, supporters must argue their case by acknowledging the concerns and explaining why they are either misplaced or worthy of much attention.
The suggestion that further negotiations are to take place to produce an "acceptable" report suggests that the politics of coalition government are doing the country harm in a certain way. Given the sensitivities involved, all the information should be available so that people can reach their own conclusions, rather than being left with the suspicion(猜疑)that facts are being replaced by political beliefs.
