Our body clock，or natural body rhythm，influences our energy and alertness．Paying attention to it can help us choose the suitable time of day when we best perform specific tasks．

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．

1.If we know our natural body rhythm well, we can ．

A．find out the suitable time to do specific tasks

B．organize our time around work demands

C．do whatever our body feels like doing

D．be sure to be healthy

2.Which of the following is NOT true?

A．Our alertness is influenced by our natural body rhythm

B．Doing whatever your body feels like is very difficult in our modem society．

C．Obeying our body clock is good for our health．

D．Disrupting our natural body rhythm can lead to obesity．

3.According to Steve Key，which of the following is NOT true?

A．When our body clock synchronizes the rhythms of its natural processes，we can do better．

B．When it comes to cognitive（认知的）work，most people perform best in the late morning．

C．As body temperature rises before awakening in the morning，our concentration gradually improves．

D．We concentrate better in the late morning than between noon and 4 pm．

4.Inspiration（灵感）to solve a difficult problem will most probably come to us ．

A．when we get up in the morning

B．when we are tired in the evening

C．when we are full of energy in the late morning

D．when we are asleep at night

5.Which of the following can be the suitable title for the passage?

A．What is natural body rhythm?

B．Natural body rhythm is good for us．

When another old cave is discovered in the south of France，it is not usual news．Rather，it is art ordinary event．Such discoveries are so frequent these days that hardly anybody pays heed to them．However，when the Lascaux cave complex was discovered in 1940，the world was amazed．Painted directly on its walls were hundreds of scenes showing how people lived thousands of years ago．The scenes show people hunting animals，such as bison or wild cats．Other images show birds and，most noticeably，horses，which appear in more than 300 wall images，by far outnumbering all other animals．

Early artists drawing these animals accomplished a monumental and difficult task．They did not limit themselves to the easily accessible walls but carried their painting materials to spaces that required climbing steep walls or crawling into narrow passages in the Lascaux complex．

Unfortunately，the paintings have been exposed to the destructive action of water and temperature changes，which easily wear the images away．Because the Lascaux caves have many entrances，air movement has also damaged the images inside．

Although they are not out in the open air, where natural light would have destroyed them long ago，many of the images have been destroyed and are barely recognizable．To prevent further damage，the site was closed to tourists in 1963，23 years after it was discovered．

Researchers have developed new software using smart phones’GPS and imaging abilities that determine the exact location of distant objects as well as monitor the speed and direction of moving objects．The software could eventually allow smart phone-armed soldiers to target the location of their enemies．On the home front，the software could be used by everyone，including golfers judging distance to the green and biologists documenting the location of a rare animal without disturbing it．

“The great advantage of a Smartphone is that it provides so many tools in a single，readily available，relatively inexpensive package，”said Qia Wang，a doctoral student who led the development of the software．“For example，on the battlefield，a soldier needs a rangefinder，compass，GPS and other tools to get information before calling in an air strike．With our software，the soldier can have all those instruments in one device that can be purchased off the shelf．When that soldier returns from War，she can use the same Software to protect her family by clocking a speeder near her children’s school and catching the criminal on video．”

Wang and his colleagues developed their software to locate and track：

Targets of known size—when the size of the target is known．a single image is enough to pinpoint the target’s location．

Targets of unknown size—If the exact size of a target is unknown，the software uses two images to triangulate the location of the target·

Moving targets—By taking a short video of a moving target，the smartphone software can calculate how fast the target is moving and in what direction it is going.

“Currently，our software is limited by the physical abilities of smartphone hardware，but the devices are improving rapidly，”Wang said．“We expect that improvements in GPS accuracy，battery life and camera resolution will allow our software to make even more accurate observations．”

1.From Paragraph 1 we can know that the new software can.

A．determine the speed of moving objects

B．1ocate objects in the distance exactly

C．defend soldiers against their enemies

D．help biologists protect rare animal

2.The example given by Qia Wang is meant to .

C．show the benefits of the software

D．present the functions of smartphones

3.How does the software calculate the speed of a moving object?

A．By taking a short video．

B．By locating its position.

C．By taking a single image．

D．By measuring real-life size.

4.What’s Qia Wang’s attitude towards the future of the software?

A．Casual． B．Optimistic． C．Cautious．D．Flexible

5.What is the best title of the text?

A．Qia Wang，a Talented Doctoral Student

B．Use Smartphones to Their Full Potential

When I was about 13, my father would take me on short outings on Saturdays. On the way home, Dad stopped at the Dairy Queen for lO-cent ice creams.

I’ll tell you one more thing. We another trip the next week. As we the center. I said,” Dad, would you like an ice cream today? My treat.”
