The reality，however，is that most of us organize their time around work demands，school deadlines，commuting or social events．Doing whatever your body feels like doing is a luxury in today"s fast-paced modem society．
But that doesn"t mean it isn"t worth trying．Obeying our body clock has significant health benefits．Disrupting our natural body rhythm，on the other hand，has been linked to problems such as depression，obesity，or headache，says Steve Key，a biology professor．
When the body clock can synchronize（使……同步）the rhythms of its natural processes，it “gives us an advantage in daily life”，says Key．
According to him，when it comes to cognitive（认知的）work，most adults perform best in the late morning．As our body temperature starts to rise just before awakening in the morning and continues to increase until midday，our memory，alertness and concentration gradually improve．
However，he adds，our ability to concentrate typically starts to decrease soon thereafter．Most of us are more easily distracted（分心）between noon and 4 pm．
Alertness also tends to fall after eating a meal and sleepiness tends to peak around 2 pm，making that a good time for a nap．
Surprisingly, tiredness may increase our creative powers．For most adults，problems that require open ended thinking are often best dealt with in the evening when they are tired， according to a study in the journal Thinking & Reasoning．
When choosing a time of day to exercise，paying attention to your body clock can improve results．Physical performance is usually best from about 3 to 6 pm，says Michael Smolensky，a professor of biomedical engineering．
Of course, not everyone"s body clock is the same，making it even harder to synchronize natural rhythms with daily plans．

In a laboratory test, a house built with conventional techniques is falling apart in hurricane-force winds.
The survivor has stronger shingles, thicker roof boards, and metal straps holding floors together.
Wind tunnel tests were done by the Insurance Institute for Business & Home Safety. It says stronger construction costs a little more, but holds up much better to extreme weather.
The growing number of unusually strong storms, like Typhoon Haiyan, has convinced the Chairman of the U. S. Senate Homeland Security Committee, Tom Carper, that extreme weather is the “new norm（标准）.”
"Extreme weather events have increased in frequency over the past 50 years and are expected to become even more common, more intense, and more costly," said Carper.
Hurricane Sandy hit beachfront businesses along the U.S. East Coast, including Carper"s home state. Insurance companies had to pay out huge claims. To limit such losses, the insurance industry can raise premiums（保险费） for businesses in vulnerable（易受攻击的）locations and offer discounts to clients who make their buildings more resilient with upgraded construction techniques.
Managing risks is the job of insurance brokers like Kevin Connelly of the Graham Company, who spoke to VOA via Skype.
“We are either going to price your insurance at a huge markup, or we are not going to write (sell it) it at all, which is just as bad obviously," said Connelly.
Drought is another suspected consequence of climate change, and dry ground means more wildfires in California. Current mathematical models of climate change do a poor job of predicting the economic impact of drought and other weather events, says Massachusetts Institute of Technology Professor Robert Pindyck, who spoke via Skype.
“I think all we can do, taking all of that into account, is come up with some very rough numbers, very rough estimates, "said Pindyck. "Consensus estimates that maybe experts provide, that give us a view of what would the catastrophic outcome look like if we don’t do anything?”
To help deal with this serious problem, Pindyck says policymakers should take actions such as imposing a tax on carbon dioxide emissions. A carbon tax would encourage companies and families to use less energy and generate fewer of the gases thought to be driving changes in the climate. But other analysts say it is unlikely a new tax will get approval in the U.S. Congress any time soon.

Experts say dyslexia affects about five to ten percent of the population of the United State. Researchers have long known that people with dyslexia write or read words and letters backwards in the wrong order.
But a new study shows that people with dyslexia may have trouble redirecting（重新传入） their attention between senses, from seeing something to hearing something. The study suggests something that might help dyslexic people learn more quickly - play video games.
Vanessa Harrar of Britain"s University of Oxford led the study. She reported the findings in the journal Current Biology. The study suggests that dyslexic people may have trouble moving quickly from what they read to what they hear. Doctor Harrar calls this a "sluggish shifting of attention across the senses."
"So, if you are trying to read something and then trying to listen to somebody who"s reading aloud and you"re trying to follow along with what they are reading -- they have to switch their attention from hearing what they are saying to looking at the piece of paper and back again. So we found they have quite sluggish shifting of attention across the senses," said Harrar.
In the study, Doctor Harrar tested 17 people with dyslexia, and 19 others without reading problems. The volunteers were asked to push a button as quickly as possible when they heard a sound, saw a light or experienced both together. Doctor Harrar compared the speed of their reactions.
She found that people with dyslexia were just as fast as the others when they saw only a picture or heard only a sound. But the dyslexics had a slower reaction time when they heard a sound and saw a picture at the same time.
Doctor Harrar feels like playing action video games could help dyslexic people shift from seeing to hearing more quickly. She adds that images in video games force the eyes to move and focus quickly.
"Video game types of things pop out of here and there, they move your eyes around the screen quite quickly in response to things quite quickly, and the more you play a video game the faster you get that kind of thing. So, the video game is really training the attention system to move quickly," said Harrar.
The study also shows that dyslexic people have the most difficulty going between what they saw and what they heard, this may have an effect on how dyslexic children are taught how to read.
When children learn the alphabet，they usually see the letter first and then hear the sound, or they see and hear the letter at the same time. The study shows that dyslexics might learn more quickly if they hear the sound of a letter or word first before seeing it.

You have to learn and get ready to become versatile in your reading. The fact that you are studying medicine in school does not mean that you should not know one or two things on politics.
Many people have complained to me that they find it hard to read stuffs like novels but I just shake my head in pity for them because it is obvious they have failed to realize the truth in that wise saying by Margaret Fuller that “today a READER, tomorrow a LEADER!”
When you read, you get to “see” so many places and it will be as if you have visited those places in real life. This is because reading will improve your imagination and creativity and understanding. You also get experience from learning about how people dealt with their various problems thereby saving you from going through the pains and difficulties they must have gone through!
Reading will also help you in improving your vocabulary because you will certainly start coming across so many new words which you will try as much as possible to get accustomed to with the help of the dictionary! The good thing about increasing your vocabulary is that it will also improve your thinking ability. After all, we think in words and the more words you know, the easier it will become for you to express yourself or your thoughts.
And when you read, make sure you read so wide because the more you read, the more you know and the more you know the more intelligent you can become.
小题1:According to the author, what should students do in terms of reading?
| A．They needn’t read unless the exams come. |
| B．They should read books about intelligence. |
| C．They must read about politics when their major is medicine. |
| D．They should read as wide as possible. |
| A．interested | B．many-sided | C．content | D．confident |
| A．Increase your ability for reading |
| B．Read wide and improve your vocabulary |
| C．Reading improves your intelligence |
| D．Reading makes you a leader tomorrow |
| A．You will get used to referring to the dictionary when meeting with new words. |
| B．You will have less difficulty expressing your opinions. |
