Article: As a child, I loved the natural world. Maybe it had something to do with growing up in a small town. Maybe it was because nature had so many secrets and I was thrilled to be a detective, uncovering them one by one. I'm sure that when people from my generation think back to their childhoods, many recall a tree house, family picnics, or a passion for fishing, hunting, or horseback riding. Most of us had an occasional appetite for dirt as we explored backyards and nearby vacant lots. As someone who grew up in such a world, I enthusiastically encourage parents to bring back that happy childhood pastime of letting kids get muddy once in a while. I have more than my own experience to show as evidence that this is a good thing: Study after study indicates that children grow up healthier and happier when they experience a direct connection to nature. Just as importantly, those young people are also far more likely to value the natural world when they've developed a connection to it. The need for this has never been greater than it is today. Our natural world is extraordinary in its diversity and complexity, but it's also under tremendous threat. In the past decade, countless tropical rainforests and coral reefs have been lost forever due to human activities, and many more are critically endangered. These areas don't just house animals and plants found nowhere else on the planet; they also provide important economic services that benefit human health. Streams make fresh water clean; forests reduce flooding; tree provide medicines and insects pollinate (......) crops. The natural world represents an economic backbone for the future of local communities by promoting tourism and local people's livelihoods. The damage to the earth's living systems is fast approaching irreversible "tipping points," and although we now have a wealth of technological tools--both to understand the threats and to assist with solutions--there's still no substitute for a connection to the real world when it comes to understanding the... Question: The author writes the passage mainly to_. Yes or no, is the answer "advise parents to let kids experience nature"?

Article: Carl studied in our middle school three years ago. Last August his father found a job in another city and his family moved there. He began to study in the new school and we often write to each other. He often tells me something about the city where he lives now and his studies in the school. So I can know what happens to him. Last Friday Carl came to our city again. He hoped to accompany his old grandpa during the summer holiday. He was taller and stronger than before. We swam in the river outside the city together and had a picnic on the island. It surprised me that he had learnt to cook when we were traveling in the wild forest. He told me his parents were both busy and sometimes he stayed at home and he had to look after himself. "How do you like your school?" I asked. "Wonderful," said the young man." It has a tall building and there 're two chemistry labs, two biology labs and three physics ones. And its library is big and there're plenty of books in it." "I can see you are satisfied with it." "Yes," he answered. "But our geography teacher often says it himself in class." "So does our new history teacher." I said. "But he doesn't notice it. He often talks on and on in a flow of the eloquence , but none of us listens to him." Question: Carl came back to our city to _ . Yes or no, is the answer "look after his grandpa"?

Q: Article: Charlie Chaplin was one of the greatest and widely loved silent movie stars. From "Easy Street" (1917) to "Modern Times" (1936), he made many of the funniest and most popular films of his time. He was best known for his character, the naive and lovable Little Tramp. The Little Tramp, a well meaning man in a raggedy suit with cane, always found himself wobbling into awkward situations and strangely wobbling away. More than any other figure, it is this kind-hearted character that we associate with the time before the talkies (sound films). Born in London in 1889, Chaplin first visited America with a theater company in 1907. Appearing as "Billy" in the play "Sherlock Holmes", the young Chaplin toured the country twice. On his second tour, he met Mack Sennett and was signed to Keystone Studios to act in films. In 1914 Chaplin made his first one-reeler, "Making a Living". That same year he made thirty-four more short films, including "Caught in a Cabaret", "Caught in the Rain", "The Face on the Bar-Room Floor", and "His Trysting Place". These early silent shorts allowed very little time for anything but physical comedy, and Chaplin was a master at it. Though Chaplin is of the silent movie era, we see his achievements carried through in the films of today. With the appearance of the feature-length talkies, the need for more subtle acting became apparent. To maintain the audience's attention throughout a six-reel film, an actor needed to move beyond constant comedy. Chaplin had demanded this depth long before anyone else. His strictness and concern for the processes of acting and directing made his films great and led the way to a new, more sophisticated, cinema. Question: What do you think is the passage about? Yes or no, is the answer "An introduction of Chaplin"?
A: No
