Before human’s history, in the middle of an ocean, miles from the nearest island, an undersea volcano broke out. The hot liquid rock piled higher and higher and spread wider and wider. In this way, an island rose up in the sea.
As time went on, hot sun and cool rains made the rock split and break into pieces. Sea waves dashed against the rock. In this way, soil and sand came into being.
Nothing lived on the naked soil. And then the wind and birds brought plant seeds, spiders and other little creatures there. Only plants could grow at first. Only they, in sunlight, could produce food from the minerals of the soil, water and air. While many animals landed on the island, they could find no food. A spider wove its web in vain, because there were no insects for its web to catch. Insects couldn’t stay until there were plants for them to eat. So plants had to be the pioneer life on this new island.

A. tirelessly B. uselessly C. fearlessly D. effortlessly

People with bigger brains ftend to score higher on standardized tests of intelligence， according to new study findings.
However， the study author Dr Michael A.McDaniel of the Virginia Commonwealth University in Richmond emphasized that these findings represent a general trend， and people with small heads should not automatically believe they are less intelligent. For instance， Albert Einstein’s brain was “not particularly large”， McDaniel noted. “There’s some relationship between brain size and intelligence on the average， but there’s plenty of room for exceptions，” he said.
Interest in the relationship between brain size and intelligence grew in the1830s， when German anatomist(解剖学家) Frederich Tiedmann wrote that he believed there was “an unquestionable connection between the size of the brain and the mental energy displayed by the individual man”. Since that statement， scientists have conducted numerous studies to determine if Tiedmann’s assertion was， in fact， correct. Most studies have looked into the link between head size and intelligence. More recently， however， researchers have published additional studies on brain size and intelligence， measured using MRI scan(核磁共振成像扫描).
For his study， McDaniel analyzed more than 20 studies that looked into the relationship between brain size and intelligence in a total of 1,530 people. The studies showed that on the average， people with larger brain volume tended to be more intelligent. The relationship between brain volume and intelligence was stronger in women than men， and in adults than in children. McDaniel notes in the journal Intelligence.
McDaniel is not sure why the relationship was stronger for adults and women. “Other research has shown that women， on the average， tend to have smaller brains than men， but score just as well—if not higher—in tests of intelligence，” he said.
McDaniel insisted that the relationship between brain size and intelligence is not a “perfect” one. “One can certainly find lots of examples of smaller-sized people who are highly intelligent，” he said， “But， on the average， the relationship holds.”. What does the text mainly talk about？
| A．MRI scans are applied to intelligence. |

The temperature is rising again in the Arctic. The sea ice area has dropped to one of the lowest levels on record， climate scientists reported last week.
“The new Arctic Report Card tells a story of widespread and continued effects of a warming Arctic，” said Jackie Richter-Menge of the US’s Cold Regions Research and Engineering Laboratory.
“This isn’t just a climatological (气候学的) effect. It impacts the people that live there，” she added.
Scientists concerned about global warming focus on the Arctic because that is a region where the effects are expected to be felt first， and that has been the case in recent years.
There was a slowdown in Arctic warming in 2009， but in the first half of 2010 warming was near a record pace. The monthly readings were over 4 degrees Celsius above normal in northern Canada， according to the report card. The report card was prepared by 69 researchers in eight countries.
Researchers said last winter’s big snow storms that struck some Northern countries were tied to higher Arctic temperatures.
“Normally the cold air is bottled up in the Arctic，” said Jim Overland of the US National Oceanic and Atmospheric Administration. “But last December and February， winds that normally blow west to east across the Arctic were instead bringing the colder air south，” he said.
“As we lose more sea ice... warming in the atmosphere can create more of these winter storms，” Overland said.
There is a powerful connection between ice cover and air temperatures， Richter-Menge explained. When temperatures warm， ice melts. When ice melts it shows darker surfaces underneath ， which absorb more heat. “That， in turn， causes more melting and on the cycle goes，” she said.
In September the Arctic sea ice extent was the third smallest in the last 30 years， added Don Perovich of the US Army Laboratory. He said the three smallest ice covers have occurred in the last four years. Scientists care so much about the warming in the Arctic region because .
| A．the climate in the Arctic doesn’t change much |
| B．global warming effects are most serious in the Arctic region |
| C．there has been a major decrease of Arctic warming in recent years |
| D．by studying the region they can make predictions about the future impact of global warming |
. Which of the following shows that the Arctic is getting warmer？
A. The surface of the sea ice in Arctic is getting darker and darker.
B. The Arctic sea ice extent has disappeared over the last 30 years.
C. The sea ice extent has increased to one of the highest levels on record.
What does the underlined word “cycle” refer to？
| A．Ice giving off heat when it melts. |
| B．Higher temperatures bringing more storms. |
| C．The cause and the result of the melting. |
| D．The life of the people living in the Arctic getting worse. |
According to researchers what led to big snow storms attacking some Northern countries last winter？

Healthy eating begins with learning how to “eat smart”. It’s not just what you eat，. how you eat. Pay attention to what you eat and choosing foods that are both nourishing
enjoyable helps support an overall healthy diet.
Take time to chew your food： Chew your food slowly， savoring every bite. We tend to rush through our meals， forgetting to actually taste the flavors and feel the textures(质地) of is in our mouths. Reconnect with
joy of eating.
Avoid stress while eating： Avoid eating while working， driving， arguing， or watching TV. Try taking some deep breaths before beginning your meal， or light candles and play soothing music to create a relaxing atmosphere.
Listen to your body： Ask if you are really hungry. You may really be thirsty， so try drinking a glass of water first. During a meal， stop eating before you feel full. It actually takes a few minutes
your brain to tell your body that it has had
food， so eat slowly.
Eat early： Starting your day a healthy breakfast can jumpstart your metabolism(新陈代谢)， and eating early in the day gives your body time to work those calories off.
Sitting on the peaceful coast of Galapagos Islands. Ecuador, watching the sun move quietly into the sea, you shouldn’t forget that Charles Darwin (1809-1882) arrived here in 1835. He stayed on the islands for five weeks, observing various animals. This finally inspired (启发) his famous work, On the Origin of Species. You can certainly follow Darwin’s footsteps and enjoy a trip from four to seven days to the islands.
The islands are certainly a paradise (天堂) for wildlife, as there are no natural killers on the islands and the number of boats and visitors is under government control. Though you cannot walk freely as Darwin did about 200 years ago, each day is as impressive as it could be.
The most well-known animals of the Galapagos is the giant tortoise(巨型海龟), which can be seen moving slowly around the highlands of Sanra Cruz, the second largest island in the archipelago(群岛). Some of these creatures are so old that they might have been seen in their youth by Darwin himself.
Despite strict control over activities and timing, your stay on the Galapagos will be remembered as a chain of incomparable pictures: diving with sea lions that swim and play within inches of you; feeling small sharks touch your feet as you swim; and, most magically, seeing a whale and her baby surface with a great breath of air.
Travelling between the islands and observing the wildlife that so inspired Darwin, you will feel as though you are getting a special view of an untouched world. At night you will sleep on board the ship, leaving the wildlife in complete occupation of the islands, which are as undisturbed now as they have been since the beginning of time.
