Chocolate is good for your heart, skin and brain．Usually, people think that chocolate is bad for their health．They describe chocolate as“something to die for”or say“death by chocolate”．Now they should bite their tongues! Evidence is showing that some kinds of chocolate are actually good for you in the following ways:
A happier heart
Scientists at Harvard University recently examined 136 studies on cocoa—the main ingredient in chocolate and found that it does seem to strengthen the heart．Studies have shown heart benefits from increased blood flow．These benefits are the result of coca’s chemicals, which seem to prevent both cell damage and inflammation（炎癥）．
Better blood pressure
If yours is high, chocolate may help．Jeffrey Blumberg from Tufts University recently found that people with high blood pressure who ate 3．5 ounces of dark chocolate per day for two weeks saw their blood pressure drop quickly．
Muscle magic
Chocolate milk may help you recover after a hard workout（鍛煉）．In a small study at Indiana University, people who drank chocolate milk between workouts did better on a tiredness test than those who had some sports drinks．
Better for your skin．German researchers gave 24 women a half-cup of special cocoa every day．After three months, the women’s skin was moister（滑潤的）and smoother．The research shows that chocolate helps protect and increase blood flow to the skin, improving its appearance．
Brain gains
It sounds almost too good to be true, but research suggests that chocolate may improve your memory, attention span, reaction time, and problem-solving by increasing blood flow to the brain．

“Sam” the koala, the most famous survivor of Australia's worst-ever wildfires, is healing well thanks to the efforts of caretakers at a rescue—and she even has a new boyfriend, “Bob”
Sam, who captured hearts around the world after she was photographed drinking from a firefighter's water bottle, has also won the affection of "Bob", another koala whose paws were scorched, caretaker Lynn Raymond said Thursday.
Neither koala is likely to be healthy enough for release for at least four months, and both are being comforted by caretakers for their scorched paws every few hours.
Global interest in the fate of Sam has been intense since a photograph of firefighter David Tree offering her a bottle of water in a burned-out forest was splashed across the Internet, in newspapers and on television broadcasts. The telephone at the shelter has rung continually with callers eager for update on the creature's condition.
“It's crazy,” Raymond said with a laugh. "（But） everybody has been absolutely wonderful."
Sam was found moving on scorched paws by a fire patrol Sunday. Tree then held out a bottle of water for her to drink, which she eagerly accepted, holding Tree's hand as he poured water into her mouth.
After suffering second-and-third-degree burns to her paws, Sam has been sharing a cage with Bob, who took an immediate interest in her when she arrived on Sunday.
Both Sam and Bob were given painkillers when they first arrived, but they're off the drugs now. The two are still receiving antibiotics（抗生素）and have their bandages changed regularly to avoid infections.
The koalas are likely to be in the shelter at least four months, depending on how quickly their burns heal.
41．What is Sam well-known for?
A．Her falling in love with Bob.      B．Her taking part in fighting the fire.
C．Her saving a firefighter.         D．Her drinking a firefighter's water.
42．How do people show their concern about Sam?
A．They call the shelter to learn about her latest condition.
B．They take care of her via the media.

About H1N1
2009 H1N1 viruses are not spread by food. You cannot get infected with H1N1 virus from eating pork or pork products. Eating properly handled and cooked pork products is safe.
Spread of H1N1 virus is thought to occur in the same way that seasonal flu does, Viruses are transmitted mainly through droplets（小滴）from coughing or sneezing of an infected person. Keeping a safe distance is recommended. Studies have also shown that flu virus can survive on object surfaces for 2 to 8 hours. Sometimes viruses can be spread when a person touches something like the surface of a desk that is polluted with droplets, and then touches his or her eyes, nose, or mouth before washing their hands.
The symptoms of H1N1 flu virus in people include fever, cough, sore throat, runny or stuffy nose and body aches. Severe illnesses and death have occurred as a result of illness associated with this virus.
Protect-Yourself Tips
1．CDC recommends a yearly seasonal flu vaccine as the first and most important step in protecting against seasonal influenza.
2．If you get seasonal or novel H1N1 flu, anti-viral drugs can treat the flu.
3．For treatment, anti-viral drugs work best if started within the first 2 days of symptoms.
4．Cover your nose and mouth with a tissue when you cough or sneeze.
5．Wash your hands often with soap and water, especially after you cough or sneeze.
6．Avoid touching your eyes, nose or mouth. Germs spread this way.
7．Try to avoid close contact with sick people.
8．If you are sick with flu-like illness, CDC recommends that you stay home for at least 24 hours after your fever is gone except to get medical care or for other necessities.
9．Follow public health advice, and avoid crowds.
10．Be prepared in case you get sick and need to stay home for a week or so; a supply of OTC medicines, tissues and other related items might could be useful and help avoid the need to make trips out in public.

A study into character, intelligence and usefulness shows dogs are better pets than cats—but only by a whisker.
Staff at New Scientist magazine first listed the areas where cats fared better. These included having bigger brains—compared to their body size. Cats’brains also contain 1.4 million more cells, devoted to complex functions such as memory and attention, than dogs. Cats’second point was given for being more popular, with 204 million living in the top ten cat-owning nations compared to 173 million dogs in the ten countries where dogs are favored. Cats also get more attention from humans, with purrs （呼嚕聲）and miaows easily to be noticed. Although dogs can vary their barks, they cannot match the attention-seeking of cats. It is a similar story when it comes to senses. Cats can see in lower light than dogs and have a far wider hearing range and a sharper sense of smell. They are also said to be’greener’pets because their smaller appetites mean less area of land required to farm their food.
But in the other six categories examined—many of which related to getting on with humans dogs had the edge.
Dogs have a longer shared history with humans, maybe as long as 135,000 years. Cats are relative newcomers to our homes. Similarly, dogs have a greater ability to bond with their masters. Even four-month-old puppies choose a human companion over another dog. Dogs scored a third point for their better powers of understanding and following human gestures. One study found that a dog called Rico had mastered the meaning of more than 200 words. The ability to perform roles such as being a guide dog for the blind meant dogs were rated better than cats when it came to their problem-solving abilities. And they are easier to train.
With the scores tied at five-all, the deciding point fell on usefulness—with dogs coming out on top.
Dogs, studies show, help cut human stress, while taking them for walks keeps their owners fit and helps them meet new people. New Scientist says: “Dogs can hunt and guard. They can sniff out drugs and bombs; they guide blind and deaf people, find someone buried in ruins, and possibly even predict earthquakes.”
And in a conclusion certain to set off argument, it adds: “Cats are good if you have rodents （嚙齒類動物）.”
48．Which of the following is not cats’ advantage?
A．Better at grasping their owners’ instructions.
B．Having relatively larger brains.
C．Affecting the environment less.
D．More likely to drawing attention.
49．The underlined phrase “by a whisker”（paragraph 1）probably means “_________”.
A．quite considerably                   B．just a little bit
C．most significantly                  D．in some aspects
50．We can learn the fact from the passage that________ .
A．Dogs are far from satisfactory in terms of their ability to catch rodents
B．Dogs can better help people who have problems with their sight and hearing
C．Comparatively speaking, cats have a better interaction with humans
D．Dogs beat cats when it comes to their senses of sight, heating and smell
51．Which would be the best title for the passage?
A．Cats beat Dogs                     B．Fight like Cat and Dog
C．Cats versus Dogs                    D．Cats away, Dogs Play

BELIEVE it or not, the color of the tie Barack Obama wears to the inauguration（就職典禮） is now a hotly debated topic. The level of public interest in Obama’s tie might seem strange but many people believe his choice will symbolize the type of government he plans to run, as the color of a politician's tie is thought to convey ideas of power, trustworthiness and more.
Polities of ties
It may be the least practical item of male dress, but it is arguably the most expressive. In the UK and many other countries around the world, conservative（保守的）politicians may wear a blue tie and their liberal opponents a red one. In America, the colors go the other way round. The Republicans have in recent years become associated with the color red, and the Democrats with blue. But in spite of this, Bush wears blue ties more often than any other color.
What they mean
According to Sharon Haver, editor of focusonstyle, com, in America the feelings associated with colors overrule （壓制） their political significance. “A guy who wants to be regarded as strong and in charge would wear red,” Haver says. Unsurprisingly, the business tycoon Donald Trump is known for wearing red ties. But what about blue? According to Haver, “Blue is a softer color…Look at the sky. It's peaceful and calm and trustworthy.”
Selecting the right tie for the right occasion
● Perfect job interview tie
Perhaps no other tie-wearing occasion is as important as the job interview. Gilchrist, the fashion expert, advises playing it safe and choosing a conservative one. Best choices are solids, stripes or small patterns. An excellent color is burgundy（酒紅色）or another serious color. Avoid pink or yellow, which suggest that the wearer lacks gravity.
Pattern ties, Gilchrist suggests, should be limited to a maximum of three colors. A striped tie is a safe choice as this is acceptable to everyone. Last, Gilchrist recommends saving the expensive “hip” tie for those applying for glamorous creative jobs.
● Date-night tie
When picking out the fight tie for taking a girl out on a date, spend more time considering color than pattern. According to studies, women are attracted to men wearing the color blue, because blue gives the image of a "stable, faithful, constant, always there" person. So what is the worst color to wear on a date? “flattened caterpillar（毛蟲）yellow-green”, according to Gilchrist, “it will repel both sexes equally.”
52．Why are people interested in the tie that Obama wears to the inauguration?
A．Because they think the tie he wears will enable them to know about his personalities and policies.
B．Because they want to advise him on how to select an appropriate tie for such a big
occasion.
C．Because they think the ties will tell if he is trustworthy as they expected when he assumes
office.
D．Because they believe the tie is an essential part of dressing to a mature politician like
Obama.
53．What can we infer about Bush, the former president, from the passage?
A．He was probably liberal in his policies when he was in power.
B．He was a Republican when he served as president.
C．He wore only blue ties and had no ties of alternative colors.
D．He wanted to make himself unique by the tie that he wore.
54．The example of "the business tycoon Donald Trump" is given to________
A prove that color reflects people's feelings to a certain degree.
B．show that Donald is so wealthy that he can afford expensive ties.
C．tell that Donald is physically strong and can handle everything.
D．explain that red is a popular color, especially with businessmen.
55．Which of the following statements is TRUE according to the text?
A．Ties can be ignored by politicians since it is the least practical item of male dress.
B．Do choose ties carefully before dating, because it is the most important occasion.
C．Why to avoid pink or yellow in job interviews is that they don't match the atmosphere.
D．The more colorful the tie is, the more likely you'll get the job you want.
56．The underlined word "repel" in the last paragraph is most close to “________”in meaning.
A．puzzle     B．a(chǎn)ttract   C．delight     D．disgust

Kiribati covers a massive 3.5 million square kilometers stretch of the Pacific Ocean, but in population terms it is one of the smallest countries in the world, with only 100,000 people. More than half of them live in the capital Tarawa—strip of coral which measures just 450 meters at its widest point. As well as being narrow, Kiribati is extremely low lying, which makes it one of the most easily influenced countries in the world when it comes to climate change.
“We are counting the days rather than the decades…We don't have the time that we thought we had previously,” Kiribati President Anote Tong said.
Pelenise Alofa returned to Kiribati six years ago. The changes she saw led to her becoming one of the islands principal climate change campaigners. "Things began to change when I came here. I realized the king tides were big, and I told them 'have you heard of climate change, have you heard of global wanning, this is part of it, you're in it,'" Ms Alofa told SBS.
Linda Uan and her New Zealand born husband John have been documenting the changing climate in Kiribati for nearly 20 years. They didn't have to travel far to film the effects of a storm three years ago when for the first time it washed through their home. "There's been a lot of changes," Linda said, “When we were little there was a definite dry season and a definite wet season, now you can't feel the difference anymore.”
Kiribati is not just facing one knock-out punch but a whole round of killer blows. Because of its sensibility to the El Nino and La Nina weather patterns, climate scientists say droughts and floods will be more severe than in the past. Warmer seas could affect the migration patterns of fish, taking away vast taxes it gains from selling fishing licenses to foreign trawlers, while increased storms are expected to destroy crops and make the limited supply of water in the shallow water pools undrinkable.
It’s a claim the country will take to Copenhagen as it seeks to get the world's big emitters （排放者） to face up to the consequences of their actions. “It's a whole world issue,” President Tong said. “It’s a moral issue…it's almost criminal.”
57．According to the passage, we can infer that________.
A．Kiribati covers a land area of 3,500,000 km2
B．the country's average altitude is 450 meters in Kiribati
C．Kiribati is one of the countries facing the climate change calmly
D．Over fifty thousand people live in Tarawa
58．President Anote’s words are quoted in order to show________ .
A．the high pressure from time        B．the importance of measuring time
C．the different timing units         D．the personal attitude towards time
59．Which of the following statements does Ms Alofa probably agree with?
A．The tides hitting Kiribati used to be bigger than they are now.
B．Most people in the world have never heard of global warming.
C．Nobody can keep away from the effects caused by climate changes.
D．Changes in this country will make you a climate change campaigner.
60．Climate changes have brought about the consequences EXCEPT________ .
A．Severe droughts and floods        B．a(chǎn)bundant fresh water
C．fiercer storm and tide            D．changed living patterns of fish

Do your spirits soar (猛增) on a sunny day? Do you relax at the sound of flowing water?
Some scientists suggest that these contacts with nature are good for your health. In one study, hospital patients with a view of trees had shorter hospital stays and less need for pain medications. Another study indicated that prisoners with a view of the outdoors had fewer doctor visits.
“Why do we desire nature? Maybe we’re programmed to need it, since our ancestors’ survival was so dependent on their connection with nature,” suggests biologist E.O. Wilson.
Want to find out if contact with nature improves your outlook on life? Try a few of these ideas.
Hang out a bird feeder and watch the birds that visit it.
Sit down in the backyard or a nearby park. Close your eyes. What do you hear? Birds singing? The wind in the trees? Crickets (蟋蟀) chirping?
Find an anthill. Sit down and watch the ants work.
Take a walk right after a rainstorm. What looks different? Smells different?
Go barefoot on a sandy beach.
Open the curtains and the window, if the weather allows it.
On a windy day, watch the trees.
Go to a creek, river or park fountain. Listen to the sound of water in motion.
Camp out in the backyard or at a nearby state park. Use a tent or sleep on the ground.
Find a wide-open space to study the stars. Learn about the different constellations (星座).
Raise a garden. Or plant some seeds in a flowerpot.
Go hiking with your family. Talk about all of the colors you see in nature.
Take a camera and capture your nature experience.
