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.

Dear Jeremy and Alice，

Although we've been delighted to have you as neighbors, we're hoping to settle something that bothers to us. In a word, your dog—Cleo.

We've called several time about Cleo's early morning barking. It is difficult to understanding why she barks every minute she's outside. The early morning barking have been disturbing us as we are often up all night with the baby. Beside, Cleo tends to bark a average of six hours a day. This morning she starts barking even before 5 o'clock. That is too much for us, considering how closely the houses are.

We appreciate our apologies and goodwill, but we hope that you can figure a good way of settling the matter.

Sincerely,

Jack and Rose

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.

1.We can learn from the first paragraph that__________.

A. energy policy catches much attention of the public

B. the residents are in favor of the expansion of wind farms

C. many village communities are satisfied with the subsidies

D. the planning laws offer great benefits to the residents

2.Supporters think that the expansion of wind power____.

A. is more rapid than that of carbon-based power

B. guarantees an increase in energy output

C. is expected to be much better than that of nuclear power

D. agrees with EU targets for non-carbon energy generation

3.It can be inferred from the passage that____.

A. an official report will settle the energy problem

B. the two parties are divided over the issue of wind farms

C. the two parties have agreed on a further negotiation

D. political beliefs concerning energy issue go against facts

4.Which of the following reflects the author's opinion?

A. Increase political impact on energy policy.

B. Release a statement of supporters on wind farms.

C. Let the nation judge the facts about wind power.

D. Leave the two parties to reach their own conclusions.

Pick yourself up. Courage is doing you're afraid to do.

A. that B. what C. how D. whether

The behaviour of a building’s users may be at least as important as its design when it comes to energy use, according to new research from the UK Energy Research Centre (UKERC). The UK promises to reduce its carbon emissions (排放）by 80 percent by 2050, part of which will be achieved by all new homes being zero-carbon by 2016. But this report shows that sustainable building design on its own — though extremely important- is not enough to achieve such reductions: the behaviour of the people using the building has to change too.

The study suggests that the ways that people use and live in their homes have been largely ignored by existing efforts to improve energy efficiency (效率)，which instead focus on architectural and technological developments.

‘Technology is going to assist but it is not going to do everything,’explains Katy Janda, a UKERC senior researcher，‘consumption patterns of building users can defeat the most careful design. ’In other words，old habits die hard, even in the best-designed eco-home.

Another part of the problem is information. Households and bill-payers don’t have the knowledge they need to change their energy-use habits. Without specific information，it’s hard to estimate the costs and benefits of making different choices. Feedback (反馈） facilities, like smart meters and energy monitors，could help bridge this information gap by helping people see how changing their behaviour directly affects their energy use; some studies have shown that households can achieve up to 15 percent energy savings using smart meters.

Social science research has added a further dimension (方面），suggesting that individuals’behaviour in the home can be personal and cannot be predicted 一 whether people throw open their windows rather than turn down the thermostat (恒温器) , for example.

Janda argues that education is the key. She calls for a focused programme to teach people about buildings and their own behaviour in them.

1.As to energy use, the new research from UKERC stresses the importance of________.

A.zero-carbon homes B. the behaviour of building users

C.sustainable building designD. the reduction of carbon emissions

2.The underlined word “which” in Paragraph 2 refers to”________.”

A. the waysB. their homes

C.developments D. existing efforts

3.What are Katy Janda’s words mainly about?

A.The importance of changing building users, habits.

B.The necessity of making a careful building design.

C.The variety of consumption patterns of building users.

D.The role of technology in improving energy efficiency.

4.The information gap in energy use _______.

A.can be bridged by feedback facilities

B.affects the study on energy monitors

C. brings about problems for smart meters

D.will be caused by building users’ old habits

5.What does the dimension added by social science research suggest?

A.The social science research is to be furthered.

B.The education programme is under discussion.

C.The behaviour of building users is unpredictable.

D.The behaviour preference of building users is similar.

A city child’s summer is spent in the street in front of his home, and all through the long summer vacations I sat on the edge of the street and watched enviously the other boys on the block play baseball. I was never asked to take part even when one team had a member missing—not out of special cruelty, but because they took it for granted I would be no good at it. They were right, of course.

I would never forget the wonderful evening when something changed. The baseball ended about eight or eight thirty when it grew dark. Then it was the custom of the boys to retire to a little stoop(门廊) that stuck out from the candy store on the corner and that somehow had become theirs. No grownup ever sat there or attempted to. There the boys would sit, mostly talking about the games played during the day and of the game to be played tomorrow. Then long silences would fall and the boys would wander off one by one. It was just after one of those long silences that my life as an outsider changed. I can no longer remember which boy it was that summer evening who broke the silence with a question: but whoever he was, I nod to him gratefully now. “What’s in those books you’re always reading?” he asked casually. “Stories,” I answered. “What kind?” asked somebody else without much interest.

Nor do I know what drove me to behave as I did,for usually I just sat there in silence, glad enough to be allowed to reain among them; but instead of answering his question, I told them for two hours the story I was reading at the moment. The book was Sister Carrie. They listened bug-eyed and breathless. I must have told it well, but I think there was another and deeper reason that made them to keep an audience. Listening to a tale being told in the dark is one of the most ancient of man’s entertainments, but I was offering them as well, without being aware of doing it, a new and exciting experience.

The books they themselves read were the Rover Boys or Tom Swift or G.A.Henty. I had read them too, but at thirteen I had long since left them behind. Since I was much alone I had become an enthusiastic reader and I had gone through the books-for-boys series. In those days there was no reading material between children’s and grownups’books or I could find none. I had gone right fromTome Swift and His Flying Machine to Theodore Dreiser and Sister Carrie. Dreiser had hit my young mind, and they listened to me tell the story with some of the wonder that I had had in reading it.

The next night and many nights thereafter, a kind of unspoken ritual (仪式) took place. As it grew dark, I would take my place in the center of the stoop and begin the evening’s tale. Some nights, in order to taste my victory more completely, I cheated. I would stop at the most exciting part of a story by Jack London or Bret Harte, and without warning tell them that that was as far as I had gone in the book and it would have to be continued the following evening. It was not true, of course; but I had to make certain of my new-found power and position. I enjoyed the long summer evenings until school began in the fall. Other words of mine have been listened to by larger and more fashionable audiences, but for that tough and athletic one that sat close on the stoop outside the candy store, I have an unreasoning love that will last forever.
