A newly-published study has shown that loneliness can spread from one person to another, like a disease.
Researchers used information from the Framingham Study, which began in 1948. The Framingham Study gathers information about physical and mental health, personal behavior and diet. At first, the study involved about 5,000 people in the American state of Massachusetts. Now, more than 12,000 individuals are taking part.
Information from the Framingham Study showed earlier that happiness can spread from person to person. So can behaviors like littering and the ability to stop smoking.
University of Chicago psychologist John Cacioppo led the recent study. He and other researchers attempted to show how often people felt lonely. They found that the feeling of loneliness spread through social groups.
Having a social connection with a lonely person increased the chances that another individual would feel lonely. In fact, a friend of a lonely person was 52% more likely to develop feelings of loneliness. A friend of that person was 25% more likely. The researchers say this shows that a person could indirectly be affected by someone’s loneliness.
The effect was strongest among friends. Neighbors were the second most affected group. The effect was weaker on husbands and wives, and brothers and sisters. The researchers also found that loneliness spread more easily among women than men.
The New York Times newspaper reports that, on average, people experience feelings of loneliness about 48 days a year. It also found that every additional friend can decrease loneliness by about five percent, or two and a half fewer lonely days.
Loneliness has been linked to health problems like depression and sleeping difficulties. The researchers believe that knowing the causes of loneliness could help in reducing it.
The study suggests that people can take steps to stop the spread of loneliness. They can do this by helping individuals they know who may be experiencing loneliness. The result can be helpful to the whole social group.From the passage, we can learn that .

An African-American man named John Henry was the hero of former slaves and the people who built the railroads in the US in the 19th century.
John Henry was born a slave. He was known for his strength. Many people say he represents the spirit of growth in America during that period.
John Henry grew up in a world that did not let children stay children for long. Before he was six years old, he was carrying stones for workers building a nearby railroad. By the time John Henry was a young man, he was one of the best railroad workers in the country.
John Henry was asked to lead workers on a hard project, creating a tunnel through a mountain. The project required about 1,000 laborers and lasted three years. Hundreds of men became sick as a result of the hot weather and tiredness. John Henry was the strongest and fastest man. Concerned his friends might lose their jobs, he picked up their hammers and began doing their work. He worked day and night, rarely stopping to have a rest.
One day, a salesman came to the work area with a new drilling machine powered by steam. He said it could drill holes faster than twelve men working together.
John Henry looked at the machine and saw images of the future. He saw machines taking the place of America’s best laborers. He saw himself and his friends unemployed and sanding by a road, asking for food. He decided he would never let the machine take their jobs. Therefore, a competition between a man and a machine began .At first, the steam-powered drill worked twice faster. Then, John Henry started working with a hammer in each hand. He worked faster and faster. People cheered when the machine broke down and was pulled away. But they were sad to find John Henry fall to the ground, with blood spilling all around, and still holding a hammer in one of his hands.“I beat them,”he said. Then he took his last breath.What does the underlined part in Paragraph 3 most probably mean?

Think about the different ways that people use the wind. You can use it to fly a kite or to sail a boat. Wind is one of our cleanest and richest power sources, as well as one of the oldest. Evidence shows that windmills(风车) began to be used in ancient Iran back in the seventh century BC. They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power.
For many centuries, people used windmills to grind(碾碎) wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote areas began to use them to produce electricity. This allowed them to have electric lights and radios. However, by the 1940s when electricity was available to people in almost all areas of the United States, windmills were rarely used.
During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means higher cost. Today, there is a global movement to supply more and more of our electricity through the use of wind.From the text we know that windmills________.
| A．were invented by European armies |
| B．have a history of more than 2,800 years |
| C．used to supply power to radio in remote areas |
| D．have rarely been used since electricity was discovered |
What was a new use for wind power in the late 19th century?
| A．Sailing a boat. |
| B．Producing electricity. |
| C．Grinding wheat into flour. |
| D．Pumping water from underground. |
One of the reasons wind was rediscovered in the 1970s is that_______.
| A．wind power is cleaner |
| B．it is one of the oldest power sources. |
| C．it was cheaper to create energy from wind |
| D．the supply of coal and gas failed to meet needs |
What would the author probably discuss in the paragraph that follows?
| A．The advantages of wind power. |
| B．The design of wind power plants. |

When an ant dies, other ants take it out of the nest, often within an hour after its death. This behavior interests scientists and they wonder how ants know for sure—and so soon—that another ant is dead.
One scientist recently came up with a way to explain this ant behavior. Dong-Hwan Choe is a biologist, a scientist who studies animals and plants. He found that ants have a chemical on the outside of their bodies that signals to other ants, “I'm dead—take me away” when it is dead.
But there's a question to answer: As we know, if an ant is dead, it stops moving. But when an ant is sleeping or knocked unconscious, it is also not moving. However, other ants don't move the living ant out of the nest. How do they know this ant is not dead? Choe found that ants have another chemical on their bodies, which tells nearby ants something like, “Wait—I'm not dead yet” when it is not dead. Choe suspects that when an ant dies, the chemical that says, “Wait— I'm not dead yet” quickly goes away. When other ants detect the “dead” chemical without the “not dead yet” chemical, they move away the body.
To test his theory, Choe and his team put different chemicals on ants. When the scientists used the “I'm dead” chemical, other ants quickly moved the treated ant away. When the scientists used the “Wait—I'm not dead yet” chemical, other ants left the treated ant alone. Choe believes this behavior shows that the “not dead yet” chemical is stronger than the “dead” chemical when picked up by other ants. And that when an ant dies, the “not dead yet” chemical fades away. Other nearby ants then detect the remaining “dead” chemical and remove the body from the nest.
Understanding this behavior can help scientists figure out how to stop ants from invading new places and causing problems.What is the function of the first paragraph?

I must have been about fourteen then, and I put away the incident from my mind with the easy carelessness of youth. But the words, Carl Walter spoke that day, came back to me years later, and ever since have been of great value to me.
Carl Walter was my piano teacher. During one of my lessons he asked how much practicing I was doing. I said three or four hours a day.
“Do you practice in long stretches, an hour at a time?”
“I try to.”
“Well, don’t, ” he said loudly. “When you grow up, time won’t come in long stretches. Practice in minutes, whenever you can find them five or ten before school, after lunch, between household tasks. Spread the practice through the day, and piano-playing will become a part of your life.”
When I was teaching at Columbia, I wanted to write, but class periods, theme-reading, and committee meetings filled my days and evenings. For two years I got practically nothing down on paper, and my excuse was that I had no time. Then I remembered what Carl Walter had said. During the next week I conducted an experiment. Whenever I had five minutes unoccupied, I sat down and wrote a hundred words or so. To my astonishment, at the end of the week I had a rather large manuscript(手稿) ready for revision. Later on I wrote novels by the same piecemeal （零碎的）method. Though my teaching schedule had become heavier than ever, in every day there were moments which could be caught and put to use.
There is an important trick in this time-using principle: you must get into your work quickly. If you have but five minutes for writing, you can’t afford to waste it in chewing your pencil. You must make your mental preparations beforehand, and concentrate on your task almost instantly when the time comes. Fortunately, rapid concentration is easier than most of us realize.
I admit I have never learnt how to let go easily at the end of the five or ten minutes. But life can be counted on to supply interruptions. Carl Walter has had a significant influence on my life. To him I owe the discovery that even very short periods of time add up to all useful hours I need, if I throw myself into it without delay.The meaning of “stretch” in the underlined part is the same as that in the sentence “_______”
| A．The dog woke up, had a good stretch and wandered off. |
| B．Bob worked as a government official for a stretch of over twenty years. |
| C．My family wasn’t wealthy by any stretch of the imagination. |
| D．This material has a lot of stretch in it. |
Which of the following statements is TRUE?
| A．The author didn’t take the teacher’s words to heart at first. |
| B．Rapid concentration is more difficult than people imagine. |
| C．The author thanked his teacher for teaching him to work in long stretches. |
| D．Carl Walter has influenced the writer greatly since he was a student. |
We can infer that the author______.
| A．had new books published each year however busy his teaching is |
| B．is tired of interruptions in life because he always has much work |
| C．has formed a bad habit of chewing a pencil while writing his novels |
| D．makes mental preparations beforehand so as to focus on work quickly |
What is probably the best title for this text?
| A．Concentrate on Your Work | B．A Little at a Time |
| C．How I Became a Writer | D．Good Advice |
Luo Gaoqi hopes to join the increasing number of Chinese students in the United States because he wants the experience of studying in a foreign land as it will help his future job at home. “I want to try Western education because people there think differently,” said the 21-year-old who is in his final year of undergraduate studies. “I also hope to meet friends from different cultures. The social connections may help in the future.”
The latest report from the US-based institute of International Education said China, for the first time, has become the top country of origin for international students in the United States.
For Yang Fan, a journalism student, said studying in the United States is a way to escape the competition for places in China’s top universities. “Due to limited education resources, only about 60 percent of high school graduates in China enter college, and a much lower rate enters the top-level ones. “A foreign degree will definitely help when I seek a job in China,” Yang said.
Both Yang’s and Luo’s parents are supportive of them studying abroad. Neither of them is thinking of settling down in the United States after graduation.
“It is not realistic to do so. As a journalism student, there would be no advantage for me to work in the United States,” Yang said. “But in China, with a US degree and good English, I may stand out against other students who have only studied in China.”
China still needs to improve its environment for scientists and high-level talents, said Xiao Mingzheng, director of the Center for Human Resource Development and Management Research of Peking University, adding that, in particular, the country needs to improve its policies relating to research environments.
In June, the Chinese government published a plan concerning talent development for the next 10 years. In it, it has improved policies and increased budgets to attract talented students back home.Why does Luo Gaoqi wants to study in a foreign land according to his words?
| A．Because the people there are more intelligent. |
| B．Because the foreign countries are more developed. |
| C．Because he can make more friends there. |
| D．Because the culture there is different from that in China. |
What do Guo Gaoqi and Yang Fan have in common?
| A．Their major is the same, which is journalism. |
| B．Both of them want to go back to China after graduation. |
| C．Their parents are against their decision. |
| D．They are forced to study in a foreign land by their parents. |
From the passage, we can infer that _______.
| A．scientists and high-level talents need a better environment in China |
| B．the students abroad are unwilling to go back to China |
| C．China doesn’t need those people to come back to our country at all |
| D．we all need to go abroad to study and then serve our own country |
