Despite occupying a relatively small area, rainforests have an important role to play in maintaining the world and they are home to a rich (various) of medicinal plants, birds and animals.

As the lungs of the planet, rainforests have their own perfect system, ensures their own survival. The tall trees make a canopy (顶篷) of branches and leaves that protect themselves, smaller plants and the forest animals from heavy rain, dry heat (come) from the sun and strong winds. (amazing), the trees grow in such a way their leaves and branches, although close together, never actually touch those of another tree. Scientists think this is a way (prevent) the spread of any tree diseases. The ground floor of the forest is not all fallen leaves, a clear land. It is where leaves turn food for the trees and other forest life.

Worryingly, rainforests around the world are disappearing at alarming rate. A few thousand years ago, rainforests (cover) as much as 12 percent of the land surface on Earth, but today this has fallen to less than 7 percent.

After I graduated,I worked as a marketing planner at a computer company.My6 and working environment were great, yet I7 didn't feel happy doing something that held little attraction for me.After two months of working there, I made up my mind to8 and decided to do what I love, namely9 history. I have now been doing this job for over twenty years. I am fond of being with my students.

If you are in a10 where you don't love what you are learning or doing, please ask yourself what you are really11 and what you truly want for your life. Don't12 to get yourself a quick answer. Take some time to think about what career could bring13 to you.

I like this motto "Success is not the key to happiness.14, happiness is the key to success." Happiness15 the inside of you, not the outside. If you love what you are doing, you will be successful.

You send out your message and then you have to wait for an answer. This is not a problem if you need to send simple information. But if the message is more complicated, e-mail is not so good.

There is another problem with e-mail: You don't get much information from the message. You have only the words themselves. This doesn't matter if the message is just about facts or if it is not important. You can't tell much about what the e-mail sender was thinking or feeling. You may put your own feelings into the message. And this can lead to communication problems in a company.

Psychologists from England studied office workers opening their e-mail. They found that certain kinds of messages made blood pressure go up. It went up if the messages seemed angry or negative. It also went up if the messages were from the boss. It went up the highest when the messages were both negative and from the boss.

The psychologists said that people should be careful how they use e-mail at work. This is especially true for the people with top jobs in a company. They should never send important news by e-mail. They should always meet face to face with the person.

A. One reason is that e-mail is only one-way.

B. Sometimes, their blood pressure went down.

C. Their messages can easily hurt or upset people.

D. And it's easier than trying to meet with someone in person.

E. The psychologists measured the blood pressure of the workers.

F. It can help to avoid misunderstanding and strengthen relationships.

G. But it might cause trouble if the message is about something important.

To find the hidden potential in teams, it's better to try a method called "brainwriting". You start by asking group members to write down their thoughts independently. Next, they sit together and share them among the group without telling who came up with each idea. Then, each member evaluates them on his or her own, only after which do the team members come together to select and improve the most promising options. By developing and assessing ideas individually before choosing and expanding on them, the team can find and improve ideas that might not get attention otherwise.

An example of great brainwriting was in 2010 when 33 miners were trapped underground in Chile. Due to the emergency of the situation, the rescue team didn't have time for brainstorming. Rather, they established a global brainwriting system to gather individual ideas. A 24-year-old engineer came up with a tiny plastic telephone. This specialized tool ended up becoming the only means of communicating with the miners, making it possible to save them.

Research by organizational behavior scholar Anita Woolley and her colleagues helps to explain why this method works. They find that the key to collective intelligence is balanced involvement (参与). In brainstorming meetings, it's too easy for participation to become one-sided in favor of the loudest voices. The brainwriting process makes sure that all ideas are brought to the table and all voices are brought into conversation. The goal isn't to be the smartest person in the room. It's to make the room smarter.

Collective intelligence begins with individual creativity, but it doesn't end there. Individuals produce a larger number and broader range of novel ideas when they work alone. That means they not only come up with more smart ideas than groups, but also more terrible ideas. Therefore, it takes collective judgment to find the signal in the noise and bring out the best ideas.

Researchers at Washington University School of Medicine did the sleep study. The study examined 100 adults for their ability to think for an average of 4.5 years. The average age of the study subject was 75. Eighty-eight of the group had been identified as free of cognitive damage. Twelve subjects were judged very mildly damaged.

During the study, they were asked to complete several tests for signs of cognitive decline. The tests are combined into a cognitive score — the higher the score, the better. They also wore electroencephalography (EEG) devices for four to six nights to measure their brain activity during sleep.

Overall, cognitive scores declined for those who slept less than 4.5 hours or more than 6.5 hours per night — as measured by EEG (脑电图). But the scores stayed the same for those in the middle of the range.

Dr. Brendan Lacey is the director of the Washington University Sleep Medicine Center and led the research. He said, "Our study suggests that there is a sweet spot for total sleep time for best cognitive performance." "Short and long sleep times are associated with worse cognitive performance, perhaps due to insufficient sleep or poor sleep quality," Lacey added.

Greg Elder is a sleep researcher at Northumbria University in New Castle, Britain. He was surprised about the findings that sleeping longer than 6.5 hours was linked with cognitive decline. Elder wrote in The Conversation, "Each person's sleep needs are individual. If people feel rested, there is no need to change how they sleep." He also noted that it suggests that sleep quality may be the key, as opposed to simply total sleep time.

Then, Zoe received an invitation from an old school friend, Kathy, to come and stay. Kathy and her husband, Huw, had just bought a farm in north-west Wales. Zoe jumped at the chance to spend a weekend away from London, and now, ten months later, she is still on the farm.

"The moment I arrived at Kathy's farm, I loved it and I knew I wanted to stay." said Zoe. " Everything about

my past life suddenly seemed meaningless."

Zoe has been working on the farm since October of last year and says she has no regrets. "It's a hard life, physically very tiring. " she says. "In London I was stressed and often mentally exhausted. But this is a good, healthy tiredness. Here, all I need to put me in a good mood is a hot bath and one of Kathy's wonderful dinners. "

Zoe says she has never felt bored on the farm. Every day brings a new experience. Kathy has been teaching her how to ride a horse and she has learnt to drive a tractor. Since Christmas, she has been helping with the lambing-—watching a lamb being born is unbelievable, she says, "It's one of the most moving experiences I've ever had. I could never go back to city life now. "
