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.

The composing career (作曲生涯) of Albert Roussel got off to a changeable start, and received one of its biggest successes from a lie.
Roussel became an orphan (孤儿) at the age of eight and went to live with his grandfather. He built on the music he had learned from his mother, entertaining himself by reading through the family music collection and playing operatic selections and popular songs on the piano. Three years later Roussel’s grandfather died, and his mother's sister took him in. Her husband arranged for young Albert to take piano lessons. Summer vacations at a Belgian seaside added a second love to his life — the sea. He studied to be a soldier in the navy, but still made time to study music.
In the French Navy, he and two friends found time to play the music of Beethoven and other composers. Roussel also began composing. At the Church of the Trinity in Cherbourg on Christmas Day 1892, he had his first public appearance as a composer. That success encouraged Roussel to write a wedding march, and one of his fellow naval officers offered to show it to a famous conductor, Edouard Colonne. When Roussel’s friend returned with the manuscript (手稿), he reported that Colonne had advised Roussel to give up his naval career and devote his life to music.
Not long afterward, at the age of 2S, Roussel did just that. He applied the qualities that he had developed in the navy to his composing and became a major force in twentieth century French music. As for Edouard Colonne’s inspiring advice that Roussel should devote his life to music, Roussel's naval friend later admitted that he had made it up and that he had never even shown Roussel’s manuscript to the conductor.What information can we get from the second paragraph?

Jenny was a pretty five-year-old girl. One day when she and her mother were checking out at the grocery store, Jenny saw a plastic pearl (珍珠) necklace priced at $2.50. Her mother bought the necklace for her on condition that she had to do some homework to pay it off. Jenny agreed. She worked very hard every day, and soon Jenny paid off the necklace.

While income worry is a rather common problem of the aged, loneliness is another problem that aged parents may face. Of all the reasons that explain their loneliness, a large geographical distance between parents and their children is the major one. This phenomenon is commonly known as “Empty Nest syndrome”.
In order to find better chances outside their countries, many young people have gone abroad, leaving their parents behind with no clear idea of when they will return home. Their parents spend countless lonely days and nights, taking care of themselves, in the hope that someday their children will come back to stay with them. The fact that most of these young people have gone to Europeanized or Americanized societies makes it unlikely that they will hold as tightly to the value of duty as they would have if they had not left their countries. Whatever the case, it has been noted that the values they hold do not necessarily match what they actually do. This geographical and cultural distance also prevents the grown-up children from providing response in time for their aged parents living by themselves.
The situation in which grown-up children live far away from their aged parents has been described as “distant parent phenomenon”, which is common both in developed countries and in developing countries. Our society has not yet been well prepared for “Empty Nest Syndrome”.According to the passage, the loneliness of aged parents is mainly caused by ________.
| A．their earlier experience of living alone |
| B．the poor living conditions in their native countries |
| C．the common worry that they have not saved much money |
| D．the distance between where parents live and where their children live |
Many young people have gone abroad, leaving their aged parents behind, to ________.
| A．realize their dreams in foreign countries |
| B．seek a better place for their aged parents |
| C．live in the countries with more money |
| D．continue their studies abroad |
If young people go abroad, ________.
| A．they do not hold to the value of duty at all |
| B．they can give some help to their parents back home |
| C．they cannot do what they should for their parents |
| D．they believe what they actually do is right |
From the last paragraph, we can infer that ________.
| A．the situations in the developed and developing countries are different |
| B．“Empty Nest Syndrome” has arrived unexpectedly in our society |
| C．children will become independent as soon as they go abroad |
| D．the aged parents are not fully prepared for “Empty Nest Syndrome” |

Would you jump off the Great Wall of China for 300 pounds a day?
A stunt (特技表演)person is a man or woman who does all the dangerous bits of acting work in films or on TV. This can be anything from a simple fall into a swimming pool, or walking off the top of a tall building. It sounds like a job that you would have to be made to try, but there are actually lots of people who want to do it.
Sarah France, twenty-four, is one of Britain’s sixteen professional stunt women ---there are one hundred and sixty stunt men in the country. We asked Sarah how she came to be a stunt woman.
“When I was young I was trained to be a dancer, and for seven years after school I was hardly out of work. A dancer’s life is pretty short, though, and my father suggested I should think about doing stunt work after I’d given up dancing. I thought about it for the next two years and decided to have a go. For six months, I worked really hard every day. I had to learn different skills---swimming, jumping, horse -riding, etc.”
Sarah finished the course in just five months and applied to the office which decides whether you’re accepted as a professional stunt person or not. Two weeks after she was accepted, Sarah was throwing off the Great Wall of China in Superman IV.
“I was very lucky to get work so quickly. I had a small part, playing a traveler who fell off the Wall after an earthquake. The traveler’s life was saved by Superman, of course! Actually, I fell forty-five feet into a pile of cardboard boxes! You can’t use anything softer than that or you will be brought back into view of the cinema. Instead you just have to learn to fall properly. It’s quite dangerous but I enjoy it.”Quite a number of people want to do dangerous acts in films because___________.
