Christian Eijkman, a Dutch doctor, left the Netherlands for the island of Java. Many people on the island had a disease called beri-beri. He was going there to try and find a cure.
At first, Eijkman thought some kind of germ (细菌) caused beri-beri. He raised some chickens. He didn’t eat them, but made experiments on them. The local people were quite surprised at that. One day he noticed that his chickens became sick when they were fed the food most Javanese ate — refined white rice (精炼米). When he fed them with unrefined rice, also known as brown rice, they recovered. Eijkman realized that he had made an important discovery — that some things in food could prevent disease. These things were named vitamins (维生素). The Javanese were not getting enough vitamins because they had actually removed the part that contains vitamins. Later, other diseases were also found to be caused by the lack of vitamins in a person’s food.
Today many people know the importance of vitamins and they make sure they have enough vitamins from the food they eat. If they don’t, they can also take vitamin pills.The underlined word “cure” in Paragragh 1 probably means ______.

I have a friend named John Roberts who owns a horse ranch (牧马场)in San Ysidro.The last time I was there he shared a story with me. “It is a story about a young man who was the son of an itinerant horse trainer. When he was a senior,he was asked to write a paper about what he wanted to be and do when he grew up.”
That night he wrote a seven-page paper describing his goal of someday owning a horse ranch. He wrote about his dream in great detail and he even drew a diagram of a 200-acre ranch, showing the location of all the buildings,the stables and the track.
“The next day he handed it in to his teacher. Two days later he received his paper back. On the front page was a large red F with a note that read, ‘See me after class.’”
“The boy went to see the teacher after class and asked, ‘Why did I receive an F?’”
“The teacher said, ‘This is an unrealistic dream for a young boy like you. You have no money. You come from an itinerant family. You have no resources. Owning a horse ranch requires a lot of money. You have to buy the land. You have to pay for the original breeding stock and later you’ll have to pay large stud fees. There’s no way you could ever do it.’ Then the teacher added, ‘If you will rewrite this paper with a more realistic goal, I will reconsider your grade.’”
“The boy went home and asked his father what he should do. His father said, ‘Look, son, you have to make up your own mind on this. However, I think it is a very important decision for you.’”
“Finally,after sitting with it for a week, the boy turned in the same paper, making no changes at all. He stated, ‘You can keep the F and I’ll keep my dream.‘”
John continued, “I tell you this story because you are sitting in the middle of my 200-acre horse ranch. I still have that school paper framed over the fireplace.” He added, “If I had changed my paper at that time, maybe we would not have the chance to be here talking about the dreams .”What was the boy’s goal described in his seven-page paper?
A.to own a horse ranch | B.to be a senior trainer |
C.to build many buildings | D.to buy many horses. |

If your dog looks pleased to see you – it is probably because it loves the particular way you smell.
The odour of a familiar human apparently lingers like perfume in the animal’s brain – where it triggers an instinctive emotional response, research published yesterday reveals.
Our scent acts on a part of the canine brain associated with reward and the strongest reactions are produced by humans that pets know best, say scientists in America.
Gregory Berns, of Emory University in Atlanta, said: ‘While we might expect that dogs should be highly tuned to the smell of other dogs, it seems that the “reward response” is reserved for their humans.
'When humans smell the perfume or cologne of someone they love, they may have an immediate, emotional reaction that's not necessarily cognitive.
'Our experiment may be showing the same process in dogs. But since dogs are so much more olfactory(嗅觉的) than humans, their responses would likely be even more powerful than the ones we might have.
'It's one thing when you come home and your dog sees you and jumps on you and licks you and knows that good things are about to happen.
'In our experiment, however, the scent donors were not physically present.
Why do animals avoid pylons? Because they emit terrifying flashes of light that are INVISIBLE to humans.
Dolphins use sponges to protect their sensitive noses while foraging for food on the sea floor
'That means the canine brain responses were being triggered by something distant in space and time. It shows that dogs' brains have these mental representations of us that persist when we're not there.'
The university’s experiment - the first of its type - involved 12 dogs of various breeds who underwent brain scans while five different scents were placed in front of them.
The scent samples came from the subject itself, a dog the subject had never met, a dog that lived in the subject's household, a human the dog had never met, and a human that lived in the subject's household.
The familiar human scent samples were taken from someone else from the house other than the handlers during the experiment, so that none of the scent donors were physically present.
The results showed that all five scents elicited a similar response in parts of the dogs' brains involved in detecting smells. Responses were significantly stronger for the scents of familiar humans, followed by that of familiar dogs.
The findings, which were published in the journal Behavioural Processes, showed that dogs reacted strongest to the scent of a familiar human even when they were not there.
Pets trained as help or therapy dogs showed greater brain activity than the other dogs in the test.
Researchers say the findings could improve the way animals who assist wounded veterans or disabled people are selected.Why does your dog look pleased to see you ?
A.because your dog wants to play with you |
B.because your dog is hungry |
C.because your dog wants to attract your attention |
D.because your dog loves the particular way you smell. |
What’s the purpose of Emory university’s experiment ?
A.To study dog’s reaction while five different scents were placed in front of them. |
B.To learn how to get along well with dogs |
C.To know how to tell the difference between dogs |
D.To improve the way animals who assist wounded veterans or disabled people are selected. |

A.The dog’s olfactory responses would likely be even more powerful than the ones we might have. |
B.In our experiment, the scent donors were physically present. |

D.Dog’s brain responses were not being triggered(引发) by something distant in space and time. |
Three-point-four billion riders on New York City subways and buses a year. This amazing number equals one-third of all mass transit trips in the United States. Ridership is at its highest in almost 60 years in almost every American city.
A commuter advocacy group, “Straphangers Campaign,” attributes it to younger Americans, said Gene Russianoff.
“Millenials(千禧一代), those people born around the turn of the past century are much less car-oriented," he said. "They are urban. They like not owning cars, they like less responsibility and there are a lot of them."
In addition to millenials, many people believe public transit is economical and eco-friendly. In 2012 across America, people took 10.7 billion trips.
“When we talk about insurance rates going up, price of automobiles going up, then people are waking up and realizing: wait, here’s this huge asset(优点)that has been underutilized," said Richard Rudolph, chairman of the Rail Users Network. "Why not take advantage of this particular opportunity. It certainly makes more sense to get people out of automobiles into subways and into commuter and passenger railroads.”
New York is not standing still -- as passenger demand requires several major expansion projects. A new $4.5 billion subway line on New York’s Second Avenue -- which was recently excavated underneath businesses and apartment houses -- will take an overload of passengers off of other subway lines. Its first phase completion is scheduled in 2016.
People who work in New York’s financial district will soon be using a new transit subway transfer center. Almost all lines converge in lower Manhattan and the new center will give riders an easier way to get around the city and into New Jersey.
And, probably the most controversial and costly project is a $7 billion tunnel connection from Long Island into Manhattan’s Grand Central Terminal. Trains from there will have access to New York’s midtown business district.
Andrew Albert, a board member of the Metropolitan Transit Authority, said there were many other reasons the public was riding in increasing numbers.
“The system has gotten a lot more dependable. We have new cars. We have countdown clocks to tell you when the next train is coming. We have expanded facilities in places," he said.
New York’s 24-hour, 7-day-a-week, transit system costs a $1.5 billion a year to maintain. It is one of the world’s oldest, with its first subway line having opened in 1904. Who is more likely to use public transmit?
A.People living in suburb B.American young people
B.People living in the countryside D.American old people.What does the underlined word in the 5th paragragh “underutilized” mean?
A.Not be put forward | B.not be noticed |
C.not be made full use of | D.not be thought of |
What does the underlined sentence in the 6th paragragh “New York is not standing still” mean?
A.New York is taking action to expand public transmit. |
B.New York will encourage more people to use public transmit. |
C.New York will make public transmit faster. |
D.New York is waking up and realizing the importance of public transmit. |
Which is Not the reason why the public is riding subways and buses in increasing numbers.
A.Public transport facilities are better than before. |
B.Many people believe public transit is economical and eco-friendly. |
C.The system has gotten a lot more dependable. |
D.It is more convenient to ride city subways and buses. |
People say, you can not change the environment, but can change their own; you can not change the facts, but can change attitudes; you can not change the past, but can be changed now; you can not control other people, but can be masters of our own; you can not do everything well, but can be conscientious in everything; you can not about the weather, but you can change the mood; you can not choose looks, but it can show a smile.
Indeed, one key to the success lies in his (her) mind. The difference between successful people and the losers are: winners will be setbacks and difficulties due to personal ability, experience, imperfect, to emphasize the inherent, they are willing to continuously improve and develop the right direction; and the losers will blame on the opportunity, and the environment injustice, emphasizing external and uncontrollable factors that created the position of their life, they always complain, wait and give up!
In many cases, is a humble person who is looked down upon his own. Person's appearance, his family, and so a priori condition that can not be changed, but at least inner state, the spirit of the will is entirely their own control. Mentality, the final decision of life high. There is no absolute bad thing, only the mentality of the absolute poor people. If even the state of mind will not adjust, how they deal with things more complicated than the mentality of it!
No matter what the situation, a person's attitude is very important. Passion put to work, and numbness sluggish to work completely different. Emerson said: "A move toward their goals is always people who gave him the whole world to give way." On the contrary, failure is not because we do not have the strength, but because we are susceptible to all around us, used to go along with the lack of assertive, attitude unstable, easily frustrated reason.
As long as we believe that the strength of mind, change their attitude and courage to face a number of disappointments in life, do not despair, brave go on. I believe the power of mind, mind you're in the height of the final decision.The underlined word “humble” in Paragraph 3 probably means _____.
A.ignoble | B.optimistic |
C.lucky | D.stubborn |
Where can you probably find the text?
A.In a popular magazine | B.In a tourist guidebook |

B.The Power of Mind. |
C.The secret of success. |
D.The difference between successful people and the losers |
Which best describes the writer’s tone in the passage?

Eight in 10 Americans eat fast food at least once a month and half eat it every week according, to a Gallup Poll. Yet most people who eat fast food know it’s bad for them. So why do they keep eating it?
The answer is simple: the benefits of eating fast food outweigh the long-term implications for most people. However, once you read these reasons why all those trips to the drive through may be slowly killing you, you may just want to stop eating fast food after all.
1. Fast food makes you fat.
A 15-year study of over 3,000 people found that eating fast food is linked to weight gain and insulin resistance. In others words, fast food makes you fat and increases your risk of type 2 diabetes. You probably know this already. But here’s something you may not know.
2. Fast food is addictive.
The more you eat fast food, the more you crave it. One study found that fast food is “a potentially addictive substance that is most likely to create dependence in vulnerable populations.” If you eat fast food once a week or more, you may be addicted to it.
3. Fast food is affecting your kids.
According to the CDC, childhood obesity has more than doubled in children and tripled in adolescents in the past 30 years. Kids have an amazing ability to recall ads they’ve seen. Fast food marketers know this, and design ads accordingly. Research shows strong associations between increases in advertising for non-nutritious foods and rates of childhood obesity.
4. Fast food “burgers” don’t have much burger in them.
One study found that most fast food burgers are composed of about 50 percent water and the actual meat content is only 2.1 to 14.8 percent. So what makes up the rest of it, you ask? Chemical fillers and preservatives, mostly. That’s why we see read horror stories about burgers that don’t go bad.
5. Even “healthy” fast food isn’t that healthy.
Fast food restaurants are catering to consumer demands to produce healthier options. The problem is, their definition of “healthy” is quite lax. One of the healthiest dishes at Burger King, the Garden Fresh Salad Chicken Caesar with TENDERGRILL Chicken and dressing, still has almost 500 calories and 28 grams of fat, and nearly a day’s worth of sodium.
6. Fast food is inhumane to animals.
Okay, this one may not be a reason why fast is killing you, but it’s still a compelling reason to stop eating fast food. 9 billion animals were slaughtered in the US alone in 2012 and much of that meat is for your fast food burgers and chicken sandwiches. Large factory farms resemble more of a “business” than a “farm.” Animals suffer in crowded spaces where they rarely have access to the outdoors or sunlight. They are pumped full of antibiotics to combat disease, which runs rampant in these conditions. Livestock is one of the biggest sources of pollution and environmental negligence, according to the UN.
7. Fast food sodas are loaded with sugar.
High fructose corn syrup (HFCS) is the cheap sweetener most fast food restaurants use in their sodas, desserts, and many other products. Princeton University researchers linked HFCS consumption to obesity in an animal study. Rats given HFCS gained more weight and body fat than those given table sugar.How many factors are mentioned which can account for the reason why fast food is slowly killing you?
A.Seven. | B.Three. | C.Four. | D.Five. |
According to the text, we know that_____.
A.many people keep eating fast food because they know nothing about the harm which fast food will bring them |
B.fast food plays a key role in children’s growth |
C.eating fast food is connected to weight gain and insulin resistance. |
D.many fast food restaurants are can offer a good and healthy meal to consumer |
What is the purpose of the passage?
A.To help us make right decisions | B.To advise us to stop eating fast food |
C.To tell us how to keep fit | D.To encourage us to be humane to animals |
