In recent years, there has been a steady attack on salt from the doctors: salt is bad for you—regardless of your health. Politicians also got aboard. “There is a direct relationship,” US Congressman Neal Smith said, “between the amount of sodium(钠) a person consumes and heart disease, circulatory(循环的) disorders, stroke and even early death.”
Frightening, if true! But many doctors and medical researchers are now beginning to feel the salt scare has gone too far. “All these remarks and cry about salt is unnecessary,” Dr. Dustan insists. “For most of us it probably does not make much difference how much salt we eat.” Dustan’s most recent short-term study of 150 people showed that those with normal blood pressure experienced no change at all when placed on an extremely low-salt diet, or later when salt was reintroduced. Of the hypertensive(高血压的) patients, however, half of those on the low-salt diet did experience a drop in blood pressure, which returned to previous level when salt was reintroduced.
“An adequate to somewhat excessive(过度的) salt intake has probably saved many more lives than it has cost in the general population,” said Dr. John H Laragh. “So an opinion that the whole population should avoid salt makes no sense.”
Medical experts agree that everyone should practice reasonable “moderation”(节制) in salt consumption. For the average person, a moderate amount might run from four to ten grams a day, or roughly 1/2 to 1/3 teaspoons. One to two grams of salt would come from the natural sodium in food. The rest would be added in processing, preparation or at the table.
“Na is not your enemy,” says Comek’s Dr. Laragh. “Salt is the No.1 natural component of all human tissue, and the idea that you do not need it is wrong. Unless your doctor has proven that you have a salt-related health problem, there is no reason to give it up.”Why is salt attacked by doctors and politicians?
| A．It’s unnecessary. |
| B．It does no good to human health. |
| C．It is hated by most people. |
| D．It will always lead to heart disease and circulatory disorders. |
From Dr. Dustan’s study in Paragraph 2 we can infer that _____.
| A．a low-salt diet may be good to some patients |
| B．the amount of salt intake has nothing to do with one’s blood pressure |
| C．the reduction of salt intake can completely cure a hypertensive patient |
| D．an extremely low-salt diet makes no difference to anyone |
In the 3rd paragraph, Dr. Laragh implied that _____.
| A．people should not be afraid of taking much excessive salt |
| B．doctors should not advise people to avoid salt |
| C．an adequate to somewhat excessive salt intake is suggested to ill people |
| D．excessive salt intake has killed some patients in the general population |
What is the experts’ advice for average people on salt consumption?
| A．They should increase salt intake through sodium pills. |
| B．They should avoid salt as often as possible. |
| C．They should consume 1/2 to 1/3 teaspoons of salt a day. |
| D．They needn’t care about how much salt they consume. |
What is the main idea of the passage?
| A．The salt scare is not reasonable. |
| B．The cause of hypertension is disclosed. |

If you live in America in the 21st century you'll probably have to listen to a lot of people tell you how busy they are. It's become the default response when you ask anyone how they are doing:"Busy!""Crazy busy!".It is,pretty obviously,a boast disguised as a complaint. And the common response is a kind of congratulation:"That's a good problem to have,"or"Better than the opposite."
Notice it isn't generally people pulling back-to-back shifts in the ICU or commuting by bus to three minimum-wage jobs who tell you how busy they are.What those people are is not busy but tired.Exhausted!Dead on their feet.It's almost always people whose busyness is purely self-imposed:work and obligations they've taken on voluntarily,classes and activities they've "encouraged" their kids to participate in.They're busy because of their own ambition or drive or anxiety,because they're addicted to busyness and dread that they might have to face in its absence.
Almost everyone I know is busy. They feel anxious and guilty when they aren't either working or doing something to promote their work.It's something they have chosen.Busyness serves as a kind of existential reassurance(令人安心的保证），a measure against emptiness,obviously your life cannot possibly be silly or tiny or meaningless if you are so busy,completely booked,in demand every hour of the day.
Idleness is not just a vacation.It is as necessary to the brain as vitamin D is to the body,and deprived of it we suffer a mental affliction as ugly as rickets.The space and quiet that idleness provides is a necessary condition for standing back from life and seeing it whole,for making unexpected connections and waiting for the wild summer lightning strikes of inspiration."Idle dreaming is often the essence of what we do,"wrote Thomas Pynchon.Archimedes' "Eureka"in the bath, Newton's apple :history is full of stories of inspirations that come in idle moments.When many Americans say"Crazy busy", they mean______.
| A．they are really tired of their present situation |
| B．they are really proud of their present life |
| C．they are complaining about their current work |
| D．their life are full of all kinds of problems |
The writer mentions Archimedes' "Eureka"and Newton's apple to show that________.
| A．history is full of interesting stories |
| B．Archimedes and Newton were very busy, so they made great discoveries |
| C．people may get inspiration when they are idle |
| D．inspirations come from hard work |
The word "its" in the second paragraph refers to_______________________________.
| A．ambition | B．anxiety | C．busyness | D．dread |
From the article,we can infer that ___________________________________.
| A．generally people pulling back-to-back shifts in the ICU tell you they are busy |
| B．"Dead on their feet" means "being tired out" |
| C．all the kids are self-imposed due to the drive and motivation |
| D．The author seems to agree that idleness is better than busyness |
The homeless dog, known as Xiao Sa, has been following a team of cyclists for 24 days along 1,833 kilometers of highway from Kangding, Sichuan province, to Lhasa in Tibet.
Nobody knows where the white dog came from or how long she has been straying on highway G318. Netizens call her the "dog with determination" and the micro blog "Go Go Xiao Sa" recording her life has attracted more than 37,000 followers in two weeks.
A picture of Xiao Sa in the arms of a young man in front of the Potala Palace on Thursday night drew more than 4,000 comments congratulating the small dog and expressing dreams of going to Lhasa.
The young man in the picture is Zhang Heng, 22, a student in Wuhan, Hubei province. As his graduation trip, he decided to face the challenge of riding to Lhasa alone. On the way he met a lonely dog. "She was lying, tired, on the street around Yajiang, Sichuan province," he said. "So we fed her, and then she followed our team.”
"We felt she might want to come along with us, so we decided to bring her along to the end." A week later, Zhang and his buddies opened a micro blog account for her. "We thought the dog was encouraging us, and wanted others to know its story," he said. They created the name Xiao Sa by combining xiao meaning "little" with the last syllable of Lhasa.
During their journey, Xiao Sa, Zhang and his team covered more than 1,700 kilometers and climbed 10 mountains higher than 4,000 meters. Xiao Sa just ran up the mountains or along dirt roads.
"Many people stopped cycling in some sections, then took the bus, but the dog made it," he said. Zhang put the dog on the back of the bike when the team was riding downhill. "The speed can reach 70 kilometers per hour, impossible for the dog to catch us."
Zhang Heng, who accompanied Xiao Sa for 20 days, called her "a buddy and a friend". "I would like to take the dog home and take care of her. She has been a stray on the road for a long time. She needs a home." How did the netizens feel when they read the micro blog related to the dog?

Humans aren't the only species on the planet with a penchant for electronic gadgets(小配件）.Zookeepers across the US and Canada are discovering that apes also get excited about Apps.
As part of a program called"Apps for Apes",12 zoos across the two countries have been introducing iPads into the entertainment time for orangutans,the giant furry red primates native to Indonesia and Malaysia.
"We are finding that,similar to people,they like touching the tablet,watching short videos of David Attenborough for instance,and looking at other animals and orangutans," said Richard Zimmerman,founding director of Orangutan Outreach,the non-profit that runs the program.
Twice weekly,orangutans are provided with access to the tablets.The animals spend from 15 minutes to half an hour using different Apps depending on their attention span.Apps designed for children that stimulate activities such as painting,music and memory games are among the most popular Apps with the apes.
"It is a lot like when we're showing children pop-up books,"said Zimmerman,adding that the orangutans are among the most intelligent primates,with the intelligence level of a young child.
The program,which relies on donated iPads, will soon be expanding to zoos across Australia, New Zealand, Japan and Europe.The word"penchant" in the first paragraph is closest in meaning to________________.

At the onset of a northern winter, many dream of warmer climates.In 1934 the Canadian-born composer Colin Mcphee did more than dream. He set out for the island of Bali.
In his book A House in Bali,Colin Mcphee described how he first gained insight into the essence of Balinese music.For about a month he had been working on transcribing a complete score to a Balinese play he had seen. It seemed impossible that so much beauty could be achieved with a scale(音阶)of only five tones.
But the distinctive embellishments(修饰音)of the music eluded him.Fortunately a young household helper and his friend decided to assist. One morning they set two objects next to Mcphee’s piano.They were gangas--metal keyed instruments.The two boys played them in what struck Mcphee as”a fast duet(二重奏） in Morse code”.
At last the composer had found the key to Balinese music.“Wait!” Mcphee would call out from the piano as the boys flew along,“Stop!Please!That bit once more!”
Patiently the boys would stop and began again.But soon they were flying again,faster than ever, amazing Mcphee with their memory and precision. Sometimes the patterns repeated.Sometimes they opened up into something new. Then, suddenly the whole duet would fly apart and the boys would burst out laughing,breaking the spell.

When a dirty and untidy orange cat showed up in the prison yard，I was one of the first to go out there and pet it．I hadn’t touched a cat or a dog in over 20 years．I spent at least 20 minutes，knelt down behind the kitchen as the cat rolled around，relaxed．What he was expressing outwardly, I was feeling inwardly．It was an amazing bit of grace to feel him under my hand and note that I was reaching a life or another creature with something as simple as my care．
Over the next few days，there were other prisoners responding to the cat．Every yard period，a group of prisoners gathered there．They stood around talking and taking turns petting the cat．These were guys you wouldn’t usually find talking to each other．Several times I saw an officer in the group，not chasing people away, but just watching and seeming to enjoy along with the prisoners．Bowls of milk and water appeared along with bread, wisely placed under the edge of the dustbin to keep the birds from getting it．
The cat was obviously homeless and in pretty bad shape．People said that the cat came to the right place．He's getting treated like a king．This was true．but as 1 watched 1 was also thinking about what the cat was doing for us．There was a lot of talk about what's wrong with prisons in America．We need more programs．We need more psychologists or treatment of various kinds．Some may even talk about making prisons more kind．But I think what we really need is a chance to practise our own kindness．Not receive it，but give it．After more than two decades here，I know kindness is not a value that's encouraged．It's often seen as a weakness．
Instead，the culture encourages keeping your head down，minding your own business，and never letting yourself be weak．
The cat did my heart good to see the effect he had on me and the men here．By simply saying，”I need some help here”，he did something important for us．He needed us．And we needed to be needed．I believe we all do．From the passage，we can learn that the author was．

| C．the author is not content with the prison culture |
| D．caring for others is encouraged in American prisons |
