Recently a study, led by Pedro Hallal of the Federal University, suggests that nearly a third of adults, 31%, are not getting enough exercise. That rates of exercise have declined is hardly a new discovery. Since the beginning of the industrial revolution, technology and economic growth have helped to create a world in which taking exercise is more and more an option rather than a necessity. But only recently have enough good data been collected from enough places to carry out the sort of analysis Dr Hallal and his colleagues have engaged in.
There are common themes in different places. Unsurprisingly, people in rich countries are less active than those in poor ones, and old people are less active than young ones. Less obviously, women tend to exercise less than men—34% are inactive, compared with 28% of men. But there are exceptions. The women of Croatia, Finland, Iraq and Luxembourg, for example, move more than their male countrymen.
Malta wins the race for most slothful country, with 72% of adults getting too little exercise, and Swaziland and Saudi Arabia are in close behind, with 69%. In Bangladesh, just 5% of adults fail to exercise enough. Surprisingly, six Americans in ten are active enough according to Dr Hallal’s study, compared with fewer than four in ten British.
These high rates of inactivity are worrying. Human beings seem to have evolved(进化) to benefit from exercise while deliberately avoiding it whenever they can. In a state of nature it would be impossible to live a life that did not provide enough of it. But that is no longer the case. Actually lack of enough activity these days has nearly the same effect on life span(寿命) as smoking.We may learn from Paragraph 1 that_________.

When people reunite with their loved ones, it’s usually a wildly happy moment. But what is their most common response to seeing them again? It may seem strange, but most of the time they break down in tears.
Now a group of psychologists from Yale University in the US say they have found the reason why, and that crying tears of joy may well be the body’s way of restoring emotional balance.
“They seem to take place when people are unable to tolerate strong positive emotions, and people who do this seem to recover better from those strong emotions,” Oriana Aragon, the lead researcher, told The Telegraph.
Aragon and her fellow psychologists looked at hundreds of participants’ emotional responses to different things, including happy reunions（重逢）and cute babies.
Many participants said they would react in a negative or aggressive way to the positive things — to cry at happy moments and want to pinch（捏）a cute baby’s face or even tell them“I want to eat you up!”
But then researchers found that these people were able to calm down from strong emotions more quickly.
“We want a happy, middle spot. Extreme is not good. It’s hard on our bodies,” Aragon told The Washington Post.
There are many other examples of times when people respond to a positive experience with a negative emotional reaction.
At an exciting concert, fans scream in horror at their idols. People who have just had a big lottery win are often in floods of tears.
“These findings advance our understanding of how people express and control their emotions, which is importantly related to mental and physical health, the quality of relationship with others, and even how well people work together,” said Aragon.
The psychologists then went further and claimed that the reverse（颠倒）was also true. Strong negative feelings may also bring out positive expressions.
For example, people often laugh when they are nervous or they are in a difficult or frightening situation.
Also, have you ever seen a character smiling at a time of extreme sadness in a movie? Their acting is not over the top, as reacting with this type of expression is just human nature, said researchers.
What does the underlined word “they” in Paragraph 3 mean?
| A．A group of psychologists. | B．People’s loved ones. |
| C．Strong positive emotions. | D．Crying tears of joy. |
Which of the following words best describes the language style of the passage?
| A．Academic and formal. | B．Cheerful and friendly. |
| C．Humorous and concerned. | D．Serious and boring. |
We can conclude from the first two paragraphs that .
| A．crying in the happy moment can also do good |
| B．a character’s smile in a movie makes no sense |
| C．people reveal their emotions by either crying or laughing |
| D．negative emotional reaction is always harmful |
What is the purpose of the passage?
| A．To argue that crying is no worse than laughing. |
| B．To inform readers about the effect of crying and laughing. |
| C．To entertain readers by relating some happy occasions. |
| D．To instruct readers how to cry and laugh. |

Global warming will significantly increase the frequency of lightning strikes, according to a US research.
The research, published in Science, was carried out with the help of data from a US network of lightning detectors. The teams says they have calculated how much each extra degree in temperature will raise the frequency of lightning. "For every two lightning strikes in 2000, there will be three lightning strikes in 2100," said David Romps, at the University of California, Berkeley.
As well as triggering more wild fires, he said, this would alter the chemistry of the atmosphere.
The team's work reveals a new method of working out the relationship between temperature and lightning storms, by estimating the heat energy available to "fuel" storm clouds. "As the planet warms, there will be more of this fuel around, so when thunderstorms get triggered, they will be more energetic," said Prof Romps.
He and his colleagues calculated that every 1℃rise in global temperature would lead to an increase in the frequency of lightning strikes by 12%.
They validated their calculations against a year of data from the US National Lightning Detector Network, which detects an electromagnetic pulse every time lightning strikes in the US. "The resulting data is exquisite," said Dr Romps. "The position and time of every lightning strike is very accurately recorded."
As well as triggering half of the wildfires in the US, each lightning strike— a powerful electrical discharge— sparks a chemical reaction that produces a "puff" of greenhouse gases called nitrogen oxides." Lightning is the
dominant source of nitrogen oxides in the middle and upper troposphere（对流层）," said Prof Romps.
And by controlling this gas, it indirectly regulates other greenhouse gases including ozone and methane. Prof Romps said that this was an example of a large response to "what sounds like only a few degrees of warming".
A scientist at the UK Met Office said it was important to understand future lightning patterns, but cautioned that there were still uncertainties in the researchers' model that needed to be tested further. The Met Office added that the application of this forecast to other parts of the world could be limited by the fact that rainfall patterns were very uncertain in many regions.
The best title for the passage should be .
| A．Global warming causes more wildfires |
| B．A new research on the effects of global warming |
| C．Climate change will make lightning strike more |
| D．The relationship between temperature and lightning |
According to Prof. Romps, .
| A．it remains to be seen whether the lightning will trigger wildfires |
| B．the research is working out the causes of the wildfires |
| C．they detected an electromagnetic pulse every time lightning strikes in the US |
| D．lightning plays a major role in creating nitrogen oxides in the middle and upper troposphere |
What did the UK Met Office think of the result of the research?
| A．The researchers’ model was not convincing enough. |
| B．The rainfall patterns stayed stable in many areas over a long time. |
| C．The result wouldn’t be applied to other parts of the world. |
| D．No research would be needed to make sure of the result. |

“Lydia is dead. But they don’t know this yet . . .” So begins the story of this exquisite debut novel, about a Chinese American family living in 1970s small-town Ohio. Lydia is the favorite child of Marilyn and James Lee; their middle daughter, a girl who inherited her mother’s bright blue eyes and her father’s jet-black hair. Her parents are determined that Lydia will fulfill the dreams they were unable to pursue—in Marilyn’s case that her daughter become a doctor rather than a homemaker, in James’s case that Lydia be popular at school, a girl with a busy social life and the center of every party.
When Lydia’s body is found in the local lake, the delicate balancing act that has been keeping the Lee family together is destroyed, tumbling them into chaos. James, consumed by guilt, sets out on a reckless path that may destroy his marriage. Marilyn, devastated and vengeful, is determined to find a responsible party, no matter what the cost. Lydia’s older brother, Nathan, is certain that the neighborhood bad boy Jack is somehow involved. But it’s the youngest of the family—Hannah—who observes far more than anyone realizes and who may be the only one who knows the truth about what happened.
A profoundly moving story of family, history, and the meaning of home, Everything I Never Told You is both a gripping page-turner and a sensitive family portrait, exploring the divisions between cultures and the rifts within a family, and uncovering the ways in which mothers and daughters, fathers and sons, and husbands and wives struggle, all their lives, to understand one another.What type of writing is this passage?

HONG KONG — In China, the smartphone battle used to be Samsung versus Apple. But not any more .
Over the summer, a Chinese company, Xiaomi, took the No. 1 position in China’s competitive market and became the world’s third-largest phone maker in the process.
Founded in 2010 , Xiaomi was late to the game. But a clever social media strategy and a business plan that emphasized selling services that work on the phone helped Xiaomi build frenzied support from young and trendy Chinese.
With people in China expected to buy 500 million smart phones in 2015 — more than three times as many as will be sold in the United States, Xiaomi is likely to remain its place as one of the most powerful phone makers in the world’s most important market.
Now the company’s founders, who include the Chinese entrepreneur Lei Jun and the former Google executive Lin Bin, hope that status will help them take their brand globally.
Why Xiaomi gained such great success ? The reason partially lies in its fans’ participation. “Xiaomi fans have a high level of organization,” said Li Nan, vice president of the rival Meizu, “They love Xiaomi. It’s a form of idolatry.”
Han Yu, a 24-year-old studying for his master’s degree, is one of those idolaters. He, with tens of thousands of others, helps Xiaomi test its user interface by looking for bugs and offering suggestions. Much of his personal life revolves around Xiaomi. He said he was honored when his suggestion to create a private photo folder was adopted on phones by Xiaomi.
“I really enjoy the sense of participation,” Mr. Han said.
For all its success, Xiaomi’s biggest challenge looms outside China. In 2013, the company hired Hugo Barra, an old friend of Mr. Lin’s from Google, to lead the company’s international expansion. “I would put China No. 1, India two, Indonesia three, then hopefully follow with Brazil and Russia,” he said. “The developed countries with tightly controlled carrier networks are not in the top five.” The countries Lin identifies all have large populations who still have not bought their first smartphone, meaning Xiaomi has a chance.
The passage mainly tells us ______.
| A．the competition between Xiaomi and Meizu |
| B．the cooperation between Xiaomi and Samsung |
| C．the battle among Smart phone Companies |
| D．the development and success of Xiaomi |
What helped Xiaomi win the support of young and trendy Chinese?
| A．Its low price. |
| B．Its social media strategy and business plan |
| C．Its fashionable design. |
| D．Its international promotion |
Who takes charge of expanding Xiaomi’s market abroad?
| A．Hugo Barra | B．Li Nan | C．Lei Jun | D．Lei Jun |
The example of Han Yu is used to ________.
| A．tell readers that the youth like to show off |
| B．prove Han Yu is very intelligent |
| C．show Xiaomi fans’ participation and devotion |
| D．introduce the designer of photo folder |
Why Xiaomi chooses less developed countries as targeted markets?
| A．Because Xiaomi doesn’t have to pay taxes. |
| B．Because more smartphone may be sold there. |
| C．Because Xiaomi was invited to develop there. |
| D．Because the young people there love Xiaomi. |

No one should be forced to wear a uniform under any circumstance. Uniforms are controlling the human spirit and totally unnecessary in a democratic(民主的) society. Uniforms tell the world that the person who wears one has no value as an individual but only lives to function as a part of the whole. The individual in a uniform loses all self-worth.
There are those who say that wearing a uniform gives a person a sense of identification with a larger, more important concept. What could be more important than the individual himself? If an organization is so weak that it must rely on cloth and buttons to inspire its members, that organization has no right to continue its existence.
Others say that the practice of making persons wear uniforms, say in school, gets rid of all envy and competition in a matter of dress, such that a poor person who cannot afford good-quality clothing is not to be looked down upon by a wealthy person who wears expensive clothing. Those persons ignore the concepts as freedom of choice, motivation, and individuality. If all persons were to wear the same clothing, why would anyone struggle to be better? It is only a short step from forcing everyone to drive the same car, have the same type of food. When this happens, all motivation to improve one’s life is removed. Why would parents bother to work hard so that their children could have a better life than they had when they know that their children are going to be forced to have exactly the same life as they had?
Uniforms also hurt the economy(经济). Right now, billions of dollars are spent on the fashion industry yearly. Thousands of people are employed in designing, creating, and marketing different types of clothing. If everyone were forced to wear uniforms, artistic personnel would be unnecessary. Salesmen would be extra as well. Why bother to sell the only items that are available? The wearing of uniforms would destroy the fashion industry which in turn would have a wave effect on such industries as advertising and sales promotion. Without advertising, newspapers, magazines, and television would not be able to remain in business. Our entire information and entertainment industries would collapse.What is the main idea of the passage？
