1、中学英语阅读理解专练小卷(四)A relationship between the amount of adult speech children are exposed to and the concentration of myelin, a substance in the brain, has been found, researchers say.“I think the take-home message is, absolutely talking to your kids. Its literally shaping the structure of the brain,” s
2、ays the lead author, Prof. John P. Spencer of the University of East Anglia.The team find, for the 30-month-olds, larger amounts of adult speech are associated with higher quantities of myelin in language-related pathways in the brain; however, for the 6-month-olds, it goes the opposite way.While th
3、e latter (后者) is unexpected, Spencer points out one possible factor: the brains stage of development.“When babies are six months old, they experience massive growth of new nerve cells,” he says. “So the input comes in and may help extend the period of brain growth.” “While at 30 months, the brain st
4、arts to cut back some of the cell growth, and form specific connections. Thats where myelin comes in. So now the input starts to help structure the myelin,” he adds.The researchers conclude adult speech is significant for both age groups and that the more adult speech children go through, the more s
5、ensitive they will be to language. The next step for them is to figure out whether the 6-month-old babies showing that negative connection will surely turn into 30-month-old kids who show positive relationship.Dr. Saloni Krishnan, Reader in cognitive neuroscience (认知神经科学) at Royal Holloway, Universi
6、ty of London, who is not involved in the work, however, notes individual differences in language ability are linked to genetics. “Children who are exposed to more language at home and have higher myelination will also have inherited genes (经遗传获得的基因) from parents who are more excellent in languages,”
7、 she said. “No final conclusion could be made before this potential genetic effect are tested. And yet there being currently no standard around the amount of input children should receive, caregivers should not necessarily feel pressure to talk more to their children.”47Which can replace the underli

Inside there are mom-and-dad approved recipes with stories and photoseven a timelineof the familys history.“We call our cookbook culin
11、ary genealogy (烹饪家谱). We wanted the book to be our familys stories told through food, rather than just characteristic recipes,” said Sarah Leung, who co-wrote the book during the pandemic (流行病) with her parents and younger sister. “We grew up in a food-obsessed (着迷的) family. Honestly, Ive developed
12、a quarter of these recipes myself,” Sarah added. “Over time, well accomplish our goal: All family members are competent Chinese cooks.”The cookbook features dishes which might be made in a Chinese American home as well as in Chinese American takeout restaurants. “Home-style cooking and restaurant-st
13、yle cooking have equal importance, but they are different,” Sarah said, adding that the family also discussed how to be respectful of each point. “I hope the recipes will appeal to Chinese Americans, like my family, and also those less familiar with Chinese cooking.”Part of their cookbook has also b

19、the spread of Chinese cooking.Listen-and-Repeat Singing Method Benefits Foreign Language LearningHave you ever found yourself in this situation: You hear a song you used to sing when you were a childa bit of nostalgia (怀旧) or “blast from the past”, as we say. But it is not a distant childhood memory
20、. The words come back to you as clearly as when you sang them all those years ago.Researchers at the University of Edinburgh studied the relationship between music and remembering a foreign language. They found that remembering words in a song was the best way to remember even one of the most diffic
21、ult languages.Here is what they did. Researchers took 60 adults and randomly divided them into three groups of 20. Then they gave the groups three different types of “listen-and-repeat” learning conditions. Researchers had one group simply speak the words. They had the second group speak the words t
22、o a rhythm, or beat. And they asked the third group to sing the words.All three groups studied words from the Hungarian language for 15minutes. Then they took part in a series of language tests to see what they remembered.Why Hungarian, you may ask? Researchers said they chose Hungarian because not
23、many people know the language. It does not share any roots with Germanic or Romance languages, such as Italian or Spanish. After the tests were over, the singers came out on top. The people who learned these new Hungarian words by singing them showed a higher overall performance. They did the best i
