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.

To what degree can a computer achieve intelligence ? The answer to this question may lie in a newly-developed US computer program called Smarter Child and the Internet .
If you ran into Smarter Child online , you would be surprised at this kid’s huge memory .It can recite many facts . For example , Smarter Child knows every baseball player in every team this season .
He 
knows every word in the dictionary and the weather in every major city areas across the US. However , if you ask Smarter Child other questions , you get stranger answers . A question about Smarter Child’s age returns . “One year , 11 days , 16 hours , 7 minutes , and 47 seconds!” Asking where he lives gets , “In a clean room in a high-tech building in California.”
Smarter Child uses the vast information on the World W
ide Web as his memory bank . To answer questions about spelling , for instance , Smarter Child goes to American Heritage Dictionary online . For the weather , he visits www.intellicast.com.
Some scientists believe that by joining the many systems of the Internet , an artificial being with the combined knowledge of , say , Albert Einstein, Richard Nixon and Britney Spears could be born. However if Smarter Child wants to think and learn on his own like the boy-computer David in the movie A. I. , Artificial Intelligence , he must overcome two problems .
The first is that computers find it difficult to read web pages because the files are labeled in different ways . That’s why programmers need to tell Smarter Child where to look for the weather . It would be a much more difficult task to let him find it himself .
Another problem is that while Smarter Child can process (处理) information more exactly and faster than any human , he lacks common sense—a basic grounding of knowledge that is obvious to any young child .From the text we can infer that www.intellicast.com is a website .
| A．which is specially designed to help Smarter Child . |
| B．where we people can find Smarter Child |
| C．where weather forecasts are made |
| D．which is about artificial intelligence |
It is probably most difficult for Smarter Child to .
| A．tell us how to spell a difficult word |
| B．tell us show the American government is run |
| C．provide us with a famous poem by Shakespeare |
| D．learn the ability to tell right behaviors from wrong ones . |
Which of the following is TRUE according to the text ?
A．Smart Child has his own memory bank big enough for all kinds of information .
B．A.I. Artificial Intelligence is probably the name of a film about a boy-computer .
C．Smart Child can recognize different files and find information needed on his own .
D．We have similar product now which ahs the knowledge of Einstein , Nixon and Spears.Which of the following is the bet title for the passage ?
| A．A New Web Child | B．Smarter Child |
| C．The Future of Internet | D．Intelligence Development |
We often think of future．We often wonder what the world would be like in a hundred years' time.
Think of space, perhaps a permanent(永久的) station on the moon will have been set up．Perhaps people will be able to visit the moon as tourists．Cheap rockets for space travel will have been developed, permitting long journeys throughout the solar system(太阳系)．When that time comes, people will be taking holidays in space and visiting other planets．Great progress will have been discovered for the most terrible of all diseases—cancer．Pollution is a problem we must solve．In a hundred years' time it will have been controlled.
All the world will have been developed—even Antarctica．There will be large cities in Antarctica．We already have supersonic(超音速的) flight, but in a hundred years' time we will have supersonic land travel as well.
We will have used up most of earth's land to build our cities, so floating cities will have been built．The Japanese already have plans for cities of this kind．And there will be cities under the sea．The first of these will have been completed.We will have developed __________ in a hundred years' time, permitting long journeys all over the solar system.
| A．cheap rockets for space travel | B．a plane for space travel |
| C．a permanent spaceship | D．a satellite for tourists |
The last paragraph mainly talks about _____________.
| A．new ways of building cities | B．the building of cities under the sea |
| C．the building of floating cities in Japan | D．the danger which earth's land will face |
The best title for the passage is ______________.
| A．Travel in the Future | B．Future Life |

“Cool” is a word with many meanings. Its old meaning is used to expressa temperature that is a little bit cold．As the world has changed, the word has had many different meanings. “Cool” can be used to express feelings of interest in almost anything. When you see a famous car in the street, maybe you will say, “It’s cool.” You may think, “He’s so cool,” when you see your favorite footballer. We all maximize（扩大）the meaning of “cool”. You can use it instead of many words such as “new” or “surprising”. Here’s an interesting story we can use to show the way the word is used．A teacher asked her students to write about the waterfall （瀑布） they had visited．On one student’s paper was just the one sentence, “It’s so cool. ” Maybe he thought it was the best way to show what he saw and felt. But the story also shows a scarcity（缺乏）of words. Without “cool”, some people have no words to show the same meaning. So it is quite important to keep some credibility （可信性）. Can you think of many other words that make your life as colorful as the word “cool”? I can. And I think they are also very cool .We know that the word “cool” has had ________________
| A．only one meaning | B．no meanings |
| C．many different meanings | D．the same meaning |
In the passage, the word “express” means “_____________”
| A．see | B．show | C．know | D．feel |
In the passage, the writer suggests（暗示） that the word “cool”__________
| A．can be used instead of many words | B．usually means something interesting |
| C．can make your life colorful | D．may not be as cool as it seems |
The summer I was ten, my mother decided to bring us to the world of art. My brother and I were not very excited when we realized what my mother meant. What she meant was that we would have to spend one afternoon a week with her at the Fine Arts Museum. Before each visit to the museum, she made us read about artists and painting styles. It was almost as bad as being in school. Who wants to spend the summer thinking about artists when you could be with your friends at the swimming pool?
First we had to read about ancient Egyptians and their strange way of painting faces and then go to look at them at the museum. My 12-year-old brother thought this was so funny, but I was not interested. Later we had to learn about artists in the Middle Ages who painted people wearing strange long clothing. We had to look at pictures of fat babies with wings and curly (鬈曲的) hair and with no clothes on flying around the edges of paintings. I certainly couldn't see what was so great about art.
On our last visit to the museum, something happened when I saw a painting by a woman called Mary. In it, a woman was reading to a child. The colors were soft and gentle, and you could tell by the mother' s expression how happy she was just to be with the child. I couldn't stop looking at this painting ! I wanted to see every painting Mary had ever made! It was really worth looking at so many paintings to find a painter who could interest me so much.

About ten years ago, a young and very successful businessman named Josh was traveling down a Chicago neighborhood street. He was going a bit too fast in his shiny, black, Jaguar XKE, which was only two months old.
He was watching for kids rushing out from between parked cars and slowed down when he thought he saw something. As his car passed, no child came out, but a brick sailed out and — WHUMP! — it hit the Jag’s shiny black side door! SCREECH...!!!! Immediately Josh stopped the car, jumped out, seized the kid and pushed him up against a parked car. He shouted at the kid, "What was that all about and who are you? Just what are you doing?!" Building up a head of steam, he went on. “That’s my new car. That brick you threw is gonna cost you a lot of money. Why did you throw it?"
"Please, mister, please....I’m sorry! I didn’t know what else to do!" begged the boy. "I threw the brick because no one else would stop!" Tears were streaming down the boy’s face as he pointed around the parked car. "It’s my brother, mister," he said. "He rolled of the curb (路沿) and fell out of his wheelchair and I can’t lift him up. "Sobbing, the boy asked the businessman," Would you please help me get him back into his wheelchair? He’s hurt and he’s too heavy for me.”
Moved beyond words, the young businessman tried hard to swallow (咽下) the rapidly swelling lump in his throat. Straining, he lifted the young man back into the wheelchair and took out his handkerchief and wiped the scrapers and cuts, checking to see that everything was going to be OK. He then watched the younger brother push him down the sidewalk toward their home.
It was a long walk back to the black, shining Jaguar XKE — a long and slow walk. Josh never did fix the side door of his Jaguar. He kept the dent (凹痕) to remind him not to go through life so fast that someone has to throw a brick at him to get his attention. Feel for the bricks of life coming at you.
