Is bottled water better for you than tap? Or should you choose vitamin-enriched water? Experts say, skip it all． None of these products is likely to make you any healthier． Below, we look at four major myths about the benefits of drinking water． 71 Experts say there’s an easy way to judge． If you are not thirsty, your fluid intake is likely “just right”
Myth No 1: Drink eight glasses each day．
Scientists say there’s no clear health benefit of drinking so much water a day． 72 “Nobody really knows,” says Dr． Stanley Goldfarb, a kidney expert at the University of Pennsylvania．
Myth No．2：Lots of water equals healthier skin．
The body is already 60 percent water． 73 Adding a few extra glasses of water each day has a limited effect． “It’s such a tiny part of what’s in the body,” says Goldfarb． “ It’s very unlikely that one’s getting any benefit．”
Myth No．3: 74
A more accurate statement may be: Drinking water is a helpful tool for dieters． “Water is a great strategy for dieters because it has no calories,” says Madeline Fernstrom of the University of Pittsburgh． “So you can keep your mouth busy without food and get a sense of satisfaction．” But water is not magical, she adds． “Other zero-calorie options such as diet sodas are fine, too．”
Myth No． 4: It’s easy to get dehydrated（脱水的） during a workout．
Dehydration sets in when a person has lost 2 percent of his or her body weight． 75 “It’s also obvious that individuals in hot, dry climates have an increased need for water,” says Goldfarb． “But for a walk in the park, no water bottle is necessary．”
A. So where does the standard advice come from?
B. But it’s unclear whether these changes are clinically significant．
C. So for a 200-pound man, this means losing 4 pounds of water．
D. Drinking extra water leads to weight loss．
E. Drink as much water as you can．
F. So, if you take a 200-pound man, he’s 120 pounds of water．
G. But first, how do you know if you’re drinking enough water?

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？
A. Higher Arctic temperatures.
B. The melting ice.
C. The cold wind blowing west to east.
D. Cold air bottled up in the Arctic.
What is the main point of the article？
A. Last winter’s big snow-storms.
B. Winds in the Arctic region.
C. Arctic warming and its possible effects.
D. Changes to the life of people living in the Arctic.

第三部分阅读理解（共20小题；每小题2分, 满分40分）
阅读下列短文, 从每题所给的四个选项（A、B、C和D）中, 选出最佳选项, 并在答题卡上将该项涂黑。
Making greener choices and encouraging healthy lifestyles can promote your health and benefit the environment．Here are some guidelines to follow:
Choose foods thoughtfully
Americans have never had such a variety or abundance of food to choose from．Besides so many choices, we now hear about our “food print”, the amount of land needed to supply one person’s nutritional needs for a year．Do we buy cherry tomatoes from Mexico or tomatoes grown loc
ally in a hothouse? Do we get the Granny Smiths from the farmers’ market or the supermarket? Is organic produce healthier for us and the planet?
These are very complex issues that require analysis of many criteria, including the energy used in producing and transporting the food, as well as the type of soil and methods of raising the food．
Despite the complexities, t
here are some general guidelines you can follow．For instance, eat less meat or eat low on the food chain．Your doctor may have recommended you to restrict your consumption of red meat because of its too much fat content．Beyond that, there are environmental reasons, too．Raising food animals contributes substantially to climate change because a meat-based diet requires more land, energy and water than a plant-based one．
Drinking plenty of fluids is significant during hot weather or when exercising．But is bottled water the way to go? You may not think so when seeing the true costs．Based on a survey, manufacturing the 30-plus billion plastic water bottles can produce more than 2．5 million tons of carbon dioxide and use three times the amount of water in the bottle．Adding in transportation, the energy used comes to over 50 million barrels of oil equivalent （等价物）．Consequently, skip the bottled water and drink tap water, both at home and at restaurants．Additionally, bottled water is not necessarily cleaner than tap．
1．In Paragraph 2 the author puts forward three questions mainly ______．
A．to prove Americans have less food to choose from
B．to show us the shopping habits of most Americans
C．to indicate Americans tend to buy food from abroad
D．to remind people to reconsider their food purchase
2．The doctor recommends eating less red meat partly because ______．
A．it contains too much fat
B．it costs a lot in transportation
C．it is too low on the food chain
D．it isn’t related to climate change
3．According to the text, which of the following is true?
A．Americans all prefer to buy cherry tomatoes from Mexico．
B．The plant-based diet is responsible for the climate change．
C．Americans have a variety of food to choose from．
D．Organic produce is the only choice for Americans．
4．Based on the last paragraph, we know that ______．
A．bottled water is cleaner than tap water
B．tap water is economical as well as eco-friendly
C．bottled water is more available than tap water
D．tap water uses one-third the cost of bottled water
5．What is the best subtitle for the last paragraph?
A．Skip bottled water, carry tap B．Drink bottled water
C．Produce plastic water bottles D．Save water resources
