2、 guess soD.It s a pity【答案】 B5、C A decline in memory as a result of ageing can be temporarily reversed using a harmless form of electrical brain stimulation, scientists have found. The study focused on a part of cognition called working memory, the brain system that holds information for short period
3、s while we are making decisions or performing calculations. Working memory is crucial for a wide variety of tasks, such as recognising faces, doing arithmetic and navigating a new environment. Working memory is known to steadily decline with age. One factor in this decline is thought to be a disconn
4、ection between two brain networks. In the study, published in the journal Nature Neuroscience, 42 people aged 20-29 and 42 people aged 60-76 were assessed in a working memory task. The older group were slower and less accurate on the tests. The scientists then subjected them all to 25 minutes of non
5、-invasive brain stimulation. This aimed to make the two target brain regions work together by passing gentle pulses of electricity through the scalp(头皮)and into the brain. After the treatment， working memory in the older adults improved to match the younger group and the effect appeared to last for
6、50 minutes after the stimulation. Those who had scored worst to start with showed the largest improvements. While these results were exciting and promising. Dardo Tomasi, a scientist at the National Institute on Alcohol Abuse and Alcoholism in Bethesda, who was not involved in the work said that lar
7、ger studies would be needed to confirm the findings and assess how they might be applied clinically. D. James Picket e head of research at the Alzheimers Society, said, “We cant cure, prevent or even slow down dementia (痴呆 )，so it vital we explore all possible areas for treatments. Altering and corr
8、ecting the circuitry of the brain with technology is a new exciting avenue of research for dementia. Deep-brain simulation a surgical procedure used in Parkinsons, is proof of principle that this approach may one day be fruiA.The approach is successful for slowing down the decline in memoryB.Those w
9、ho had worst memory demonstrated fewer improvementsC.More researches are needed before the results are applied to patientsD.Preserving the circuitry of brain is a direction of research for dementi A【答案】 C6、Parents and toddlers who read paper books together speak and interact more when compared with
10、those who read e-books，researchers foun D.Reading with a child is a hugely important developmental activity as it helps youngsters learn new words, broadens their knowledge and provides time to bond with loved ones. So scientists wanted to see if parents and children acted differently when they read
11、 books together using traditional media versus electronic devices like tablets.To investigate, the researchers found 37 pairs of parents and healthy toddlers between two and three years ol D. They asked them to read from three different types of media: enhanced electronic books with sound effects or
12、 animation, a basic electronic book, and a print books Researchers found parents and toddlers spoke more when interacting with a paper book rather than a story on an electronic tablet. Whats more, parents used richer language when using print books compared with tablets, and collaborated more with t
13、heir children. But parents were less responsive and children were less engaged with their parents when reading e-books, said Dr. Tiffany Munzer, corresponding author of the study at the University of Michigan C.S. Mott Childrens Hospital. The findings were published in the journal Pediatrics.Munzer
14、pointed out. however, that the study was limited in several ways, including that the team did not test the toddlers reading comprehension. It was also limited by the small sample size, and the fact that the team used only one commercially-available app for the e-books. That isnt to say there is no b
15、enefit to electronic book reading compared with doing nothing. Just less compared with print books. Print books are just better for promoting rich language from their parents and more conversations between parents and children, said Munzer.Munzer said that parents always know their children best, so
16、 they should feel empowered to adjust the reading experience to what they know their children areA.To find out how they behave when they read from different medi AB.Help youngsters learn more words and broaden their knowledgeC.To provide more time to develop relationships with loved onesD.To prove that
