     Readingcan be a social activity. Think of the people who belong to book groups. They choose books to read and then meet to discuss them. Now, the website BookCrossing.com turns the page on the traditional idea of a book group.

      Members go on the site and register the books they own and would like to share. BookCrossing provides an identification number to stick inside the book. Then the person leaves it in a public place, hoping that the book will have an adventure, traveling far and wide with each new reader who finds it.

    Bruce Pederson, the managing director of BookCrossing, says, “The two things that change your life are the people you meet and books you read. BookCrossing combines both.”

    Members leave books on park benches and buses, in train stations and coffee shops. Whoever finds their book will go to the site and record where they found it.

    People who find a book can also leave a journal entry describing what they thought of it. E-mails are then sent to the BookCrossing to keep them updated about where their books have been found. Bruce peterson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.

    BookCrossing is part of a trend among people who want to get back to the “real” and not the virtual(虚拟). The site now has more than one million members in more than one hundred thirty-five countries.

    Are we getting more stupid? According to Gerald Crabtree, a scientist at Stanford University in the US, we are.  You may not want to hear this, but Crabtree believes that human intelligence reached its peak more than 2,000 years ago and ever since then has been going downhill. “If an average Greek from 1,000 BC were transported to modern times, he or she would be one of the brightest among us,” Crabtree told The Guardian.

    At the heart of Crabtree's thinking is a simple idea. In the past, intelligence was critical for survival when our ancestors had to avoid dangerous animals and hunt for food. The difference of being smart or stupid is often life or death. However, after the spread of agriculture, when our ancestors began to live in dense ( 稠密的）farming communities, the need to keep their intelligence in peak condition gradually reduced. This is not hard to understand. Most of the time,pressure is what keeps us going – you need the pressure from your teachers to finish your homework; the pressure of looking pretty prompts(促使) you to lose weight when summer comes. And the same is also true of our intelligence – if we think less, we become less smart.

    These mutations(变) are harmful to our intelligence and they were all developed in the past 3,000 years. The other evidence that Crabtree holds is in our genes. He found that among the 2,000 to 5,000 genes that we have that determine human intelligence , there are two or more mutations in each of us. However, Crabtree's theory has been criticized by some who say that early humans may have better hunting and surviving abilities, but people today have developed a more diverse intelligence. For example, spearing a tiger doesn't necessarily require more brainpower than playing chess or writing a poem. Moreover, the power of modern education means a lot more people have the opportunity to learn nowadays. “You wouldn't get Stephen Hawking 2,000 years ago. He just wouldn't exist,” Thomas Hills of the University of Warwick, UK, told Live Science. “But now we have people of his intellectual capacity doing things and making insights(洞察力) that we would never have achieved in our environment of evolutionary adaptation.”

    When her classmates were having a good time, Molly sat at the picnic table alone. She remained awkward around her classmates. She seemed unsure of what to do or say, yet I could see her eyes longing for acceptance. Many students had already decided that her friendship would not be worth the energy required to overcome the awkwardness. Others teased her. Most ignored her except for one.

    Brianna, the class clown, was making the other students laugh, as usual. “Brianna, do you see Molly down there? Would you mind walking down there and inviting her to come up here with the rest of us?”

    Brianna sighed. I could tell she didn't want to sacrifice precious minutes of her own recess (休息) to do what I was asking of her, but I also knew her heart. She often thought of others before herself— a rare character for anyone, much less a kid.

    Knowing this choice was hard for her, I reached into my pocket and pulled out a D-buck, our class currency. Though bribery (行贿) was not the ideal way to handle this situation, I needed her cooperation.

    “Here, I'll pay you for your time.”

    She offered an insincere smile, grasped the green paper, and headed down the hill.

    As the rest of the children screamed and laughed, my eyes locked on Brianna as she neared the picnic table. Molly could be difficult, and I wouldn't have been surprised if she sent Brianna back alone, refusing her invitation. When she encouraged herself to a standing position, I sighed with relief.

    A minute later, I felt a tap on my shoulder. “Here, Mrs. D.” She handed me the D-buck.

    “Why?” I asked.

    “I shouldn't keep this,” Her eyes fell to her feet, guilt radiating from her quiet voice. “I don't want Molly to think I only went to get her so I could earn a D-buck. She's my friend.”

    A moment later, they were all laughing again, and who should I see among them, laughing for the first time that week? Molly.

    Eighty-five-year old Chinese pharmacologist(药理学家) Tu Youyou became China's first winner of the Nobel Prize in Physiology or Medicine when it was announced that she was one of three scientists awarded the 2015 Nobel Prize in Physiology or Medicine for their work in developing effective drugs against parastic diseases.

    Tu was honored for developing artemisin（青蒿素）,a drug for malaria that has saved millions of lives across the globe,especially in the developing world,the Nobel Assembly at karolinska Institue disclosed on its website on Monday.Tu,a Chinese trained pharmacologist and a researcher at the China Academy of Chinese Medical Sciences in Beijing, went to Stockholm, Sweden in December to receive her award, according to Cao Hongxin, the science and technology department head of the State Administration of Traditional Chinese Medicine.

    "She was calm and said she has received lots of congratulatory calls." Cao told China Daily on Monday after he telephoned Tu to congratulate her. "It's an overdue（迟来的）honor for Tu and the world's recognition of traditional Chinese medicine," he said.

    "Tu's breakthrough in winning the Nobel Prize in a natural science is the pride of the whole nation and the whole Chinese scientific community," said Zhou Dejin, spokesman of the Chinese Academy of Science, China's national research body that consists of more than one hundred research insistutes, universities and research branches,

    "The achievement of discovering artemisinin was made in the 1970s, but it only received international recognition in later years, which suggests that we might have more achievements that have reached the Nobel Prize level but have not been recognized." Zhou said.

    Persuasion is the art of convincing someone to agree with you. According to the ancient Greeks, there are three basic tools of persuasion: ethos, pathos, and logos.

    Ethos is a speaker's way of convincing the audience that she is trustworthy, honest and reliable. One common way a speaker can develop ethos is by explaining how much experience or education she has in the field. After all, you're more likely to listen to advice about how to take care of your teeth from a dentist than a fireman. A speaker can also create ethos by convincing the audience that she is a good person. If an audience cannot trust you, you will not be able to persuade them.

    Pathos is a speaker's way of connecting with an audience's emotions. For example, a politician who is trying to convince an audience to vote for him might say that he alone can save the country from a terrible war. These words are intended to fill the audience with fear, thus making them support him. Similarly, an animal charity might show an audience pictures of injured dogs and cats, to make the viewers feel pity. If the audience feels bad for the animals, they will be more likely to donate money.

    Logos is the use of facts, statistics, or other evidence to support your argument. An audience will be more likely to believe you if you have convincing data to back up your claims. Presenting this evidence is much more persuasive than simply saying "believe me".

    Although ethos, pathos, and logos all have their strengths, they are often most effective when used together. Indeed, most speakers use a combination of ethos, pathos, and logos to persuade their audiences. So, the next time you listen to a speech, watch a commercial, or listen to a friend try to convince you to lend him some money, be on the lookout for these ancient Greek tools of persuasion.

    Last month, voters in the second Congressional District in New Orleans, Louisiana, made a historic choice. They elected Anh "Joseph" Cao a Vietnamese-American Republican party member, as their representative. It is the first time in over one hundred years that voters in this area of New Orleans elected a non-democratic Party lawmaker. And, Anh Cao is the first Vietnamese-American to be elected to the United States Congress(议会).

    Anh Cao went through difficult times to get to where he is now. He was born in Saigon in nineteen sixty-seven during the war in Vietnam. In nineteen seventy-five, North Vietnamese troops took control of Saigon. He was separated from his family for many years. Anh Cao lived with his uncle in Indian, then later moved to Houston, Texas.

    He decided to work for social justice in a non-religious way. So, he worked as a lawyer in New Orleans.

    He joined the Republican Party and became active on local and state political committees. He decided to compete against his local representative in Congress, William Jefferson, who had been in office since nineteen ninety-one. Minister Jefferson's reelection campaign was not helped by federal corruption charges against him.

    Mister Cao won the election. That night he said that never in his life did he think he could be a congressman. He said the American dream is alive and well.
