Frederic Mishkin, who's been a professor at Columbia Business School for almost 30 years, is good at solving problems and expressing ideas. Whether he's standing in front of a lecture hall or engaged in a casual conversation, his hands are always waving and pointing. When he was in graduate school, one of his professors was so annoyed by this constant gesturing that he made the young economist sit on his hands whenever he visited the professor's office. It turns out, however, that Mishkin's professor had it exactly wrong. Gesture doesn't prevent but promotes clear thought and speech. Research demonstrates that the movements we make with our hands when we talk form a kind of second language, adding information that's absent from our words. It's learning's secret code: Gesture reveals what we know. It reveals what we don't know. What's more, the agreement (or lack of agreement) between what our voices say and how our hands move offers a clue to our readiness to learn. Many of the studies establishing the importance of gesture to learning have been conducted by Susan Goldin-Meadow, a professor of psychology at the University of Chicago. "We change our minds by moving our hands," writes Goldin-Meadow in a review of this work. Particularly significant are what she calls "mismatches" between oral expression and physical gestures. A student might say that a heavier ball falls faster than a light one, for example, but make a gesture indicating that they fall at the same rate, which is correct. Such differences indicate that we're moving from one level of understanding to another. The thoughts expressed by hand motions are often our newest and most advanced ideas about the problem we're working on; we can't yet absorb these concepts into language, but we can capture them in movement.       Goldin-Meadow's more recent work strews not only that gesture shows our readiness to learn, but that it actually helps to bring learning about. It does so in two ways. First, it elicits   helpful behavior from others around us.... What can be inferred from the passage about gesture-speech mismatches? A) They can stimulate our creativity. B) Instructors should make full use of them. C) Teachers can hardly explain new concepts without them. D) They serve as a stepping stone to solving real life problems.

There's no doubt that man is the smartest. But do you know what other animals are smart, too? Dolphins Dolphins are very smart. Most of the "tricks" they're taught to do are actually behavior they would engage in on their own. They love to play, race and generally enjoy their life to the fullest. They speak a language we have yet to completely understand and like all civilized creatures, dolphins' mothers always provide their young children with guidance and possibly, love. Great apes The great ape family primarily consists of gorillas, chimpanzees and orangutans. Their brain chemistry is so similar to humans' that NASA once used chimpanzees in place of astronauts during many dangerous missions. Gorillas have been taught sign language and orangutans exist in complex familial relationships. Elephants Everyone has heard the phrase "an elephant never forgets". Elephants establish long-term friendships, recognizing and remembering their friends years later. If an elephant comes upon a fallen friend, it has even been known to feel sad. Parrots As proved by this list, parrots are very smart. They are also the only animals listed that can actually hold a conversation. Some parrots know hundreds of words by imitating humans. The birds are also capable of remembering words and using them intelligently in response to situations. Which kind of animal has a long-term memory? A) Dolphins. B) Great apes. C) Elephants. D) Parrots.

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  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 _ that China will stay committed to a peaceful development path and does not accept the logic that a country will seek hegemony(,) 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. Where can you probably NOT find this passage?
