Even when you’re extremely busy, you aren’t using your time with 100% efficiency. There are gaps in everyone’s schedule where they aren’t doing anything important. Even if your schedule has no gaps, there is probably lots of time where you aren’t working as fast or as effectively as you possibly could.
Why aren’t you completely efficient? It’s because time isn’t the limiting factor. If it were the limiting factor, people could work non-stop without breaks or any unproductive distractions (消遣). Instead, people, even those who are highly productive, need to take breaks, occasionally procrastinate (拖延) and slow down on tasks throughout the day.
The real and most important limiting factor for productivity is your energy levels to pay attention. Energy levels limit your productivity because when you’re tired, you can have enough time and still not get everything done. Your attention ability is also limited, because even if there are a million things that need to be done, you can only focus on one or two at a time.
You might not be able to add another 4-5 hours into your schedule without making some sacrifices. But even extremely busy people can add an hour or two into their schedule without cancelling (取消) anything. The reason why it’s hard to “find time” isn’t a lack of time. It’s because you don’t have enough energy left to focus on something else that needs to fit into your day.
I first suspected time wasn’t the real problem during an extremely busy period in my life over a year ago. I was extremely busy, but at that time I still exercised regularly. I had daily to-do lists with over twenty items, and I still found time to exercise. However, after a few weeks off, due to illness, I stopped exercising. I was not busy by any standards, in fact, my schedule was incredibly light. Despite this free time, I found it hard to find time to exercise. It seemed to get pushed later and later into my schedule until it was gone. How can I explain this strange experience? I believe you have known it.If someone can’t work with 100% efficiency, the most important limiting factor is ________.
| A．a schedule without gaps |
| B．breaks and distractions |
| C．the limited time |
| D．the limited energy |
The writer gives the example of himself in the last paragraph in order to ________.
| A．prove what the real limiting factor is |
| B．show us how busily he needs to work |
| C．explain how important a healthy body is |
| D．tell us what an strange experience he has |
What is the best title of the passage?
| A．Do You Really Lack Time? |
| B．How Can You Work Efficiently? |
| C．What Makes Your Energy Limited? |
| D．When Should You Do Exercise? |
Rene Descartes’ explanation of pain has long been acknowledged in medicine. He proposed that pain is a purely physical phenomenon – that tissue injury makes specific nerves send a signal to the brain, causing the mind to notice pain. The phenomenon, he said, is like pulling on a rope to ring a bell in the brain. It is hard to overstate how deeply fixed this account has become. In medicine, doctors see pain in Descartes’ terms— as a physical process, a sign of tissue injury.
The limitations of this explanation, however, have been apparent for some time, since people with obvious injuries sometimes report feeling no pain at all. Later, researchers proposed that Descartes’ model be replaced with what they called the gate control theory of pain. They argued that before pain signals reach the brain, they must first go through a gating mechanism in the spinal cord(脊髓). In some cases, this imaginary gate could simply stop pain signals from getting to the brain.
Their most amazing suggestion was that what controlled the gate was not just signals from sensory nerves but also emotions and other “output” from the brain. They were saying that pulling on the rope need not make the bell ring. The bell itself—the mind— could stop it. This theory led to a great deal of research into how such factors as mood, gender, and beliefs influence the experience of pain. In a British study, for example, researchers measured pain threshold and tolerance levels in 53 ballet dancers and 53 university students by using a common measurement: after immersing your hand in body-temperature water for two minutes to establish a baseline condition, you put your hand in a bowl of ice water and start a clock running. You mark the time when it begins to hurt: that is your pain threshold. Then you mark the time when it hurts too much to keep your hand in the water: that is your pain tolerance. The test is always stopped at 120 seconds, to prevent injury.
The results were striking. On average female students reported pain at 16 seconds and pulled their hands out of the ice water at 37 seconds. Female dancers were almost three times as long on both counts. Men in both groups had a higher threshold and tolerance for pain, but the difference between male dancers and male nondancers was nearly as large. What explains that difference? Probably it has something to do with the psychology of ballet dancers—a group known for self-discipline, physical fitness, and competitiveness, as well as by a high rate of chronic(慢性) injury. Their driven personalities and competitive culture evidently accustom them to pain. Other studies along these lines have shown that outgoing people have greater pain tolerance and that, with training, one can reduce one’s sensitivity to pain.
There is also striking evidence that very simple kinds of mental suggestion can have powerful effects on pain. In one study of 500 patients undergoing dental procedures, those who were given a placebo(安慰剂) injection and promised that it would relieve their pain had the least discomfort— not only less than the patients who got a placebo and were told nothing but also less than the patients who got actual drug without any promise that it would work.
Today it is abundantly evident that the brain is actively involved in the experience of pain and is no more bell on a string. Today every medical textbook teaches the gate control theory as fact. There’s a problem with it, though. It explains people who have injuries but feel no pain, but it doesn’t explain the reverse, which is far more common— the millions of people who experience chronic pain, such as back pain, with no signs of injury whatsoever. So where does the pain come from? The rope and clapper are gone, but the bell is still ringing.The primary purpose of the passage is to .

Tayka Hotel De Sal
Where: Tahua, Bolivia
How much: About $95 a night
Why it’s cool: You’ve stayed at hotels made of brick or wood, but salt? That’s something few can claim. Tayka Hotel de Sal is made totally of salt—including the beds (though you’ll sleep on regular mattresses(床垫) and blankets). The hotel sits on the Salar de Uyuni, a prehistoric dried-up lake that’s the world’s biggest salt flat. Builders use the salt from the 4,633-square-mile flat to make the bricks, and glue them together with a paste of wet salt that hardens when it dries. When rain starts to dissolve the hotel, the owners just mix up more salt paste to strengthen the bricks.
Green Magic Nature Resort

As you look out of your open window—there is no glass!—you watch monkeys and birds in the rain forest canopy. Later you might test your fear of heights by crossing the handmade rope bridge to the main part of the hotel, or just sit on your bamboo bed and read. You don’t even have to come down for breakfast—the hotel will send it up on the pulley-drawn “elevator”.

Tensions have erupted over some barren rocks in the Pacific that you may never have heard of, but stay tuned—this is a boundary dispute(争端) that could get ugly and some day have far-reaching consequences for China, Japan, Taiwan and the United States.
The islands in dispute are called the Senkaku chain by Japan, the Diaoyu islands by China, and the Diaoyutai by Taiwan. All three claim the islands, which are really just five small islands and three barren rocks northeast of Taiwan, 200 miles off the Chinese coast.
The latest conflict occurred when a Chinese fishing boat collided(碰撞) with two Japanese naval ships trying to stop it near the islands. The Japanese prevented the Chinese captain from leaving the place for questioning and the two countries have been exchanging angry protests.
The reason to worry is that nationalists in both China and Taiwan see the islands as unquestionably theirs and think that their government has been weak in claiming this authority.
So far, wiser heads have generally won the argument on each side, but at some point a weakened Chinese leader might try to gain the legal right with the public by pushing the issue and recovering the islands. It would be a dangerous game and would have a disastrous impact on China-Japan relations, but if successful it would raise the popularity of the Chinese government.
In reality, of course, there is zero chance that the U.S. will honor its treaty(条约) with Japan over a few barren rocks. We're not going to risk a nuclear conflict with China over some islands that may well be China's. But if we don't help, our security relationship with Japan will be at the breaking point.
So which country has a better claim to the islands? My feeling is that it's China, although the answer isn't clear-cut. Chinese navigational records show the islands as Chinese for many centuries, and a 1783 Japanese map shows them as Chinese as well. Japan purported to “discover” the islands only in 1884 and took control of them by force only in 1895 when it also grabbed Taiwan.
The best approach would be for China and Japan to agree to refer the dispute to the International Court of Justice, but realistically that won't happen. And since some believe that the area is rich with oil and gas reserves, the claims from each side have become more insistent.
As Chinese nationalism grows, as China's navy and ability to project power in the ocean gains, we could see some military conflicts over the islands.

People are being lured (引诱）onto Facebook with the promise of a fun, free service without realizing they're paying for it by giving up their personal information. Facebook then attempts to make money by selling their data to advertisers that want to send targeted messages.
Most Facebook users don't realize this is happening. Even if they know what the company is up to, they still have no idea what they're paying for Face book because people don't reallyknow what their personal data is worth.
The biggest problem, however, is that the company keeps changing the rules. Early on, you keep everything private. That was the great thing about facebook-you could create your own little private network. Last year, the company changed its privacy rules so that many things— your city, your photo, your friends' names—were set, by default(默认)to be shared with every one on the Internet.
According to Facebook's vice-president Elliot Schrage, the company is simply making changes to improve its service, and if people don't share information, they have a "less satisfying experience".
Some critics think this is more about Facebook looking to make more money. In original business model, which involved selling ads and putting them at the side of the pages totally. Who wants to look at ads when they're online connecting with their friends?
The privacy issue has already landed Facebook in hot water in Washington. In April. Senator Charles Schumer called on Facebook to change its privacy policy. He also urged the Federal Trade Commission to set guidelines for social-networking sites. "I think the senator rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them," Schrage admits.
I think that whatever Facebook has done so far to invade our privacy, it's only the beginning. That is why I'm considering deactivating(撤销）my account. Facebook is a handy site, but I'm upset by the idea that my information is in the hands of people I don't trust. That's too high a price to pay.Why do people give their personal information to Facebook according to Paragraph 1?
| A．Because they can get some money from Facebook. |
| B．Because their information is not important. |
| C．Because they are promised to have a fun and free service. |
| D．Because they can also get other people's information. |
What does the author say about most Facebook users?
| A．They are unwilling to give up their personal information. |
| B．They don't know their personal data enriches Facebook. |
| C．They don't identify themselves when using the website. |
| D．They care very much about their personal information. |
Why does Facebook make changes to its rules according to Elliot Schrage?
| A．To give better service to its users. | B．To obey to the Federal guidelines. |
| C．To improve its users' connection. | D．To expand its business. |
Why does Senator Charles Schumer support publicly?
| A．Setting guidelines for advertising on websites. |
| B．Banning the sharing of users' personal information. |
| C．Making regulations for social-networking sites. |
| D．Removing ads from all social-networking sites. |
