Chinese President Xi Jinping stressed Wednesday that the socialist path China has followed is "correct," and it is the choice of the “history and people.”

    Citing(引用) the remarkable achievements China has made over the past 37 years when it initiated the reform and opening-up policy, Xi noted that it only took several decades for China to complete the journey the developed countries have gone through for centuries.

    “That fully shows that the Chinese people are following a correct path,” the president said while addressing a banquet hosted by Lord Mayor of the City of London Alan Yarrow on Wednesday evening.

    Meanwhile, he pledged that China will stay committed to a peaceful development path and does not accept the logic that a country will seek hegemony(霸权，领导权) once it gets strong.

    “No one and nothing — in any reason — can influence China's determination and will to pursue the path of peaceful development,” he said.

    In his speech, the president also explained in detail about the development of friendly relations between China and Britain, citing tea culture, literature, movies, TV dramas, football and cultural exchanges.

    He specifically referred to Shakespeare's influence on him by sharing the story of his youth time in the countryside, when he was deeply attracted by the master's works.

    “The China-Britain friendship has been deeply rooted in the hearts of our two peoples. And there is a solid foundation in public opinion and in society for the two countries to grow long-term relations,” he added.

    Mark felt that it was time for him to take part in his community，so he went to the neighborhood meeting after work. The area city council(委员会)woman was leading a discussion about how the quality of life was on the decline. The neighborhood faced many problems. Mark looked at the charts taped to the walls. There were charts for parking problems, crime, and for problems in vacant buildings. Mark read from the charts, “Police patrols(巡逻)cut back, illegal parking up 20%.” People were supposed to suggest solutions to the council woman. It was too much for Mark. “The problems are too big,” he thought. He turned to the man next to him and said, “I think this is a waste of my time. Nothing I can do would make a difference here.”

    As he neared the bus stop on his way home, Mark saw a woman carrying a grocery bag, and a baby. As Mark got closer, her other child，a little boy, suddenly dashed into the street. The woman tried to reach for him, but as she moved, her bag shifted(滑落), and groceries started to fall out.Mark ran to take the boy's arm and led him back to his mother. “You gotta stay with Mom,” he said. Then he picked up the fallen groceries while the woman smiled in relief. “Thanks,” she said. “You've got great timing.” “Just being neighborly,” Mark said. As he rode home, he glanced at the poster near his seat in the bus. Small acts of kindness add up.Mark smiled and thought, “Maybe that's a good place to start.”

    The Shiants, remote, cliff-edged islands off the coast of Scotland are home to 350,000 seabirds. This is the starting point for National Geographic contributor Adam Nicolson's new book, The Seabirds Cry. Celebrating 10 species in detail, he describes the unbelievable recovery of seabirds and the many adaptations that have enabled them to survive and navigate the oceans, while sounding a loud call for their conservation among severely falling numbers.

    Speaking from his home in Sussex, England, Nicolson explains why guillemot (海雀) colonies are information exchange centers: how new research is showing that those long-distance travelers. The shearwaters, "smell" their way across the globe; and what we can do to support seabird populations.

    National Geographic has just kicked off Year of the Bird with a cover story by Jonathan Franzen titled "Why Birds Matter ". The beginning of Year of the Bird is beneficial to birds. Nicolson said, "I'll ask you the same question-why? For me, these seabirds are symbols of uniqueness. There is so much on the land where the rest of the living world seems to be controlled by us, but when you go to seabird colonies, there is this pumping, loud and raging uniqueness. It's a glance of the untouched world. "

    "The reason why it's untouched is that, until recently, we have not controlled the oceans that the seabirds depend on. More of them have survived in greater numbers than most other creatures in the developed world, where huge amounts of the animal kingdom have been removed by us. And so one reason these birds matter is that they are symbols of what the world might be if we hadn't done so much damage to it. "He added.

    "Seabirds also tend to disappear; they're not reliably of our world, due to their migration and habits of life. Very deep in our consciousness is a sense that they are ambassadors from another world. And witnessing and feeling that is, I think, one of the great enlargers of life." Nicolson explained.

    Passenger pigeons (旅鸽) once flew over much of the United States in unbelievable numbers. Written accounts from the 18th and 19th centuries described flocks (群) so large that they darkened the sky for hours.

    It was calculated that when its population reached its highest point, there were more than 3 billion passenger pigeons—a number equal to 24 to 40 percent of the total bird population in the United States, making it perhaps the most abundant bird in the world. Even as late as 1870 when their numbers had already become smaller, a flock believed to be 1 mile wide and 320 miles (about 515 kilometers) long was seen near Cincinnati.

    Sadly the abundance of passenger pigeons may have been their undoing. Where the birds were most abundant, people believed there was an ever-lasting supply and killed them by the thousands.

    Commercial hunters attracted them to small clearings with grain waited until pigeons had settled to feed, then threw large nets over them, taking hundreds at a time. The birds were shipped to large cities and sold in restaurants.

    By the closing decades of the 19th century, the hardwood forests where passenger pigeons nested had been damaged by American's need for wood, which scattered (驱散) the flocks and forced the birds to go farther north, where cold temperatures and storms contributed to their decline. Soon the great flocks were gone, never to be seen again.

    In 1897, the state of Michigan passed a law prohibiting the killing of passenger pigeons but by then, no sizable flocks had been seen in the state for 10 years. The last confirmed wild pigeon in the United States was shot by a boy in Pike County, Ohio, in 1900. For a time, a few birds survived under human care. The last of them, known affectionately as Martha, died at the Cincinnati Zoological Garden on September 1, 1914.

    Throughout history scientists have risked their health and their lives in their search for the truth.

    Sir Isaac Newton, the seventeenth century scientist, was very smart, but that didn't stop him from doing some pretty stupid things. In his laboratory in Cambridge he often did the strangest experiments. Once, while testing how light passes through lenses (晶状体), he put a long needle into his eye, pushed it to the back, and then moved it around just to see what would happen. Luckily, nothing long-lasting did. On another occasion he stared at the sun for as long as he could bear, to discover what effect this would have on his sight. Again he escaped suffering permanent damage, though he had to spend some days in a darkened room before his eyes recovered.

    In the 1750s the Swedish chemist Karl Scheele was the first person to find a way to produce phosphorus (磷). He in fact discovered eight more chemical elements including chlorine (氯), though he didn't get any praise for them. He was a very clever scientist, but his one failing was a curious habit of tasting a little of every substance he worked with. This risky practice finally caught up with him, and in 1786 he was found dead in his laboratory surrounded by a large number of dangerous chemicals, any of which might have been responsible for his death.

    Eugene Shoemaker was a respected geologist. He spent a large part of his life studying craters (火山口) on the moon, and how they were formed, and later did research into the comets of the planet Jupiter. In 1997 he and his wife were in the Australian desert where they went every year to search for places where comets might have hit the earth. While driving in the Tanami desert, normally one of the emptiest places in the world, another vehicle crashed into them and Shoemaker was killed on the spot. Some of his ashes (骨灰) were sent to the moon aboard the Lunar Prospector spacecraft and left there — he is the only person who has had this honor.
