【正文】 s heart health.（1）Which of the following agrees with Dr. Chockalingam39。Dr. Chockalingam says a smile may be one way to help. He tells his patients to smile 20 times an hour. To some, that might seem like a lot of smiling. Or some might even feel foolish ... smiling for seemingly no reason. But a smile does not involve drugs. It is not invasive like a surgical operation. It is free and it has no bad side effects. Experts note that an unhealthy lifestyle can put you at great risk of heart disease and stroke. So doctors urge us to eat healthy foods, get exercise, stop smoking and limit our alcohol intake. But there is something else you can do. And it is free and easy. Smile! 【點評】本題考點涉及細節(jié)理解和主旨大意兩個題型的考查，是一篇科研類閱讀，考生需要準確掌握細節(jié)信息，同時根據(jù)上下文進行推理，歸納，從而選出正確答案。 （4）考查主旨大意。故選D。根據(jù)第一段中的“By the age of one, they can recognize the significant noises around them and group them into a language.”可知一歲的嬰兒和成人相比更能識別出周圍的重要聲音，故選D。language consists of sound and meaning【答案】 （1）D（2）D（3）A（4）C 【解析】【分析】本文是一篇說明文，人們一直以來認為語言是思想的產(chǎn)物，但是有新的研究表明飲食對于語言也會產(chǎn)生一些影響。.

Beyond these particular changes, the story highlights the way in which everything distinctively human is both material and spiritual: speech must bine sound and meaning, and the meaning can39。 Hunter gatherer languages very seldom use the sounds known as labiodentals (唇齒音)－those such as f and v－that are made by touching the lower lip with the upper teeth. Only two of the hundreds of Australian aboriginal languages use them, for example. But in cultures that have discovered farming, these consonants (輔音) are much more mon. The argument goes that farmers eat more cooked food and more dairy than hunter gatherers. Either way, they need to chew mush less, and to bite less with their front teeth. So farmers grew up with smaller lower jaws and more of an overbite than their ancestors who had to bite through harder foods. It became easier for them to make the labiodental consonants instead of purely labial (唇音) ones: one example is that f e to take the place of p. Romans said pater but English speakers (unless they39。d rather think of language as product of our thought Babies have an astonishing talent that adults entirely lose. By the age of one, they can recognise the significant noises around them and group them into a language. When we have lost this capacity as adults, it bees enormously difficult to distinguish between sounds that are glaringly different to a native speaker. It all sounds Greek to us. This is because the range of possible sounds that humans use to convey meaning may be as high as 2,000, but few languages use more than 100 and even then the significant noises－the phonemes (音素) of a language－each cover a range of sounds and so vague distinctions which would change the meaning of a word in other languages. 【點評】本題考點涉及細節(jié)理解，推理判斷和主旨大意三個題型的考查，是一篇科研類閱讀，要求考生在捕捉細節(jié)信息的基礎上，進一步根據(jù)上下文的邏輯關系，進行分析，推理，概括和歸納，從而選出正確答案。 （4）考查主旨大意。根據(jù)倒數(shù)第二段中的“Many species can understand the difference between quantities and use this to search for food, make decisions and solve problems. But numerical cognition, such as exact number and arithmetic operations, requires a more plex level of processing.”許多物種都能理解數(shù)量之間的差異，并以此來尋找食物、做出決定和解決問題。根據(jù)第五段中的“If math doesn39?！笨芍?，RMIT大學 的此前的研究表明，一些靈長類動物、鳥類、嬰兒甚至蜘蛛都可以加減法。A Discovery About the Tiny Brain of BeesB.Bees can recogize the exact number.B.requires addition and subtraction two plex processingB.Longterm rules and short term working memory.C.t require a massive brain, there might also be new ways for us to include interactions of both longterm rules and working memory in designs to improve rapid AI learning of new problems,” said Dyer.
