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 arc 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 underlined sentence “the opposite is true” in Paragraph 2 probably means that trees .

D.know more about the complex “tree societies” |
The underlined word “it” in the last paragraph refers to .
A.how “tree societies” work |
B.how trees grow old |
C.how forestry industry develops |
D.how young trees survive |
What would be the best title for the passage?
A.Old Trees Communicate Like Humans |
B.Young Trees Are In Need Of Protection |
C.Trees Are More Awesome Thart You Think |
D.Trees Contribute To Our Society |
People in South Korea who feel they can no longer bear the stress of everyday life now can choose to stay in a prison to relax and think deeply.
In a society where pressure to do well in school and find highly-paid jobs is intense, a former lawyer came up with an extreme relaxation idea. Kwon Yong-seok created the “Prison Inside Me”—a stress-reduction center with a punishment theme. People come here to cut themselves off from the outside world and pay to be kept in 60-square-foot (5.6-square-meter) cells (囚室).
Located on the outskirts of Hongcheon, about 58 miles (93 km) northeast of Seoul, “Prison Inside Me” came to life after Mr. Kwon voluntarily asked to spend time behind bars for “healing reasons,” but his request was turned down. “I didn’t know how to stop working back then,” he said. “I felt like I was being swept away against my will, and it seemed I couldn’t control my own life.” So, Kwon and his wife Roh Ji-hyang decided to take matters into their own hands, and designed and built a prison-like spiritual center. The construction was completed in June last year and cost about 2 billion won ($19 million).
The facility includes 28 cells, furnished with only a toilet, a sink and a small table, where guests can spend time alone, thinking about life and enjoying private thinking periods. Moreover, guests can also join group thinking periods in the hall, where they are given instructions on how to free themselves from what Mr. Kwon calls the “inner prison” to find inner peace.
According to the Wall Street Journal, hundreds of stressed South Koreans are checking in at the stress-reduction facility to think about their lives and regain control of it. A two-night stay at “Prison Inside Me” costs 150,000 won ($146).
Mr. Kwon and his wife explained that at the beginning they had a different plan for the “relaxation center,” and imagined a longer stay for their guests, but, given that people weren’t able to take more time off, they had to reduce the length of stays to just two days.
Park Woo-sub, a guest at “Prison Inside Me,” said the experience helped him a lot. “This is my third time in prison. Being kept in a prison makes me hard to breathe, but it also offers time to focus only on me and spend some quiet time with myself.”
Others said the experience would have been more helpful if the conditions had been poorer, like in a real prison.Paragraph 3 mainly tells us _______________.
A.where “Prison Inside Me” is located |
B.what people can do in “Prison Inside Me” |
C.how “Prison Inside Me” came into being |
D.when “Prison Inside Me” was completed |
Which of the statements is true?
A.people in South Korea prefer living under great pressure |
B.Mr. Kwon had intended to let guests stay at “Prison Inside Me” for over two days |
C.most people in South Korea can not afford to stay at “Prison Inside Me” |
D.the 28 cells are well furnished, but with no toilets in them |
We can know from the passage that _______________.
A.many people have been kept in such a prison at least three times |
B.it is not a good idea for people to focus only on themselves |
C.people find it not difficult to breathe though the prison is small |
D.some still felt a bit unsatisfied as the conditions weren’t poor enough |
Who should go to the “Prison Inside Me”?
A.A successful businessman |
B.A criminal at large |
C.A primary student |

What is the main idea of the passage?
A.Many South Koreans voluntarily go to “prison” to reduce stress. |

D.South Koreans have found the best way to deal with everyday pressure. |
Most people agree that honesty is a good thing. But does Mother Nature agree? Animals can’t talk, but can they lie in other ways? Can they lie with their bodies and behavior?
Animal experts may not call it lying, but they do agree that many animals, from birds to chimpanzees, behave dishonestly to fool other animals. Why? Dishonesty often helps them survive.
Many kinds of birds are very successful at fooling other animals. For example, a bird called the plover sometimes pretends to be hurt in order to protect its young. When a predator (猎食动物) gets close to its nest, the plover leads the predator away from the nest. How? It pretends to have a broken wing. The predator follows the “hurt” adult, leaving the baby birds safe in the nest.
Another kind of bird, the scrub jay, buries its food so it always has something to eat. Scrub jays are also thieves. They watch where others bury their food and steal it. But clever scrub jays seem to know when a thief is watching them. So they go back later, unbury the food, and bury it again somewhere else.
Birds called cuckoos have found a way to have babies without doing much work. How? They don’t make nests. Instead, they get into other birds’ nests secretly. Then they lay their eggs and fly away. When the baby birds come out, their adoptive parents feed them.
Chimpanzees, or chimps, can also be sneaky. After a fight, the losing chimp will give its hand to the other. When the winning chimp puts out its hand, too, the chimps are friendly again. But an animal expert once saw a losing chimp take the winner’s hand and start fighting again.
Chimps are sneaky in other ways, too. When chimps find food that they love, such as bananas, it is natural for them to cry out. Then other chimps come running. But some clever chimps learn to cry very softly when they find food. That way, other chimps don’t hear them, and they don’t need to share their food.
As children, many of us learn the saying "You can't fool Mother Nature." But maybe you can't trust her, either.A plover protects its young from a predator by _______________.

D.How does honesty help animals survive? |
My wife Laura and I were on the beach, with three of our children, taking pictures of shore birds near our home in Alaska when we spotted a bear. The bear was thin and small, moving aimlessly.
Just a few minutes later, I heard my daughter shouting, “Dad! The bear is right behind us!”An aggressive bear will usually rush forward to frighten away its enemy but would suddenly stop at the last minute. This one was silent and its ears pinned back—the sign (迹象) of an animal that is going in for the kill. And it was a cold April day. The bear behaved abnormally, probably because of hunger.
I held my camera tripod (三脚架) in both hands to form a barrier as the bear rushed into me. Its huge head was level with my chest and shoulders, and the tripod stuck across its mouth. It bit down and I found myself supporting its weight. I knew I would not be able to hold it for long.
Even so, this was a fight I had to win: I was all that stood between the bear and my family, who would stand little chance of running faster than a brown bear.
The bear hit at the camera, cutting it off the tripod. I raised my left arm to protect my face; the beast held tightly on the tripod and pressed it into my side. My arm could not move, and I sensed that my bones were going to break.
Drawing back my free hand, I struck the bear as hard as I could for five to six times. The bear opened its mouth and I grasped its fur, trying to push it away. I was actually wrestling (扭打) with the bear at this point. Then, as suddenly as it had begun, the fight ended. The bear moved back toward the forest, before returning for another attack— the first time I felt panic.
Apparently satisfied that we caused no further threat, the bear moved off, destroying a fence as it went. My arm was injured, but the outcome for us could hardly have been better. I’m proud that my family remained clear-headed when panic could have led to a very different outcome.The brown bear approached the family in order to _______________.
A.catch shore birds |
B.start an attack |
C.protect the children |
D.set up a barrier for itself |
The bear finally went away after it _______________.
A.felt safe | B.got injured |
C.found some food | D.took away the camera |
The writer and his family survived mainly due to their _______________.
A.pride | B.patience |
C.calmness | D.cautiousness |
