C Putting more green space around an elementary school may help students develop some mental abilities, a study suggests. Researchers tested students repeatedly over the course of a year on attentiveness and working memory, which is the ability to keep something in mind temporarily for performing a task. The study tracked more than 2,000 students in 36 primary schools in Barcelona, Spain. The pupils were in the second to fourth grade when the study began. Overall, students whose schools are surrounded by more green space improve more pupils from schools with less green space. “Policy makers should know that more green space around the school is better for cognitive (認(rèn)知的 ) development and that they should make sure that kids can see and play in green areas,” one author, Mark Nieuwenhuijsen of the Center for Research in Environmental Epidemiology in Barcelona, said in an . “Existing urban schools should think about replacing concrete or other hard surfaces with green space, and even a few trees may help,” he suggested. The researchers used satellite images to group schools according to how much green space appeared on the school ground and within about 55 yards of the school’s surrounding property. Their analysis indicated that differences in socioeconomic factors between schools did not account for the study oute. Sally Augustin, a psychologist in La Grange Park, Illinois, who used research on how people react to their surroundings to consult on design of buildings, products and services, said the results make sense to her. Augustin, who did not participate in the new study, said the results fit with previous findings that views of nature help children and adults lower stress and perform mental tasks better. 28.

How are the schools classified by the researchers? A. By green space. B. By test scores. C. By size. D. By position. 31. Why is Augustin mentioned in the passage? A. To introduce another interesting study. B. To make the findings of the study more convincing. C. To present new evidence for the study. D. To show a different viewpoint. D In the top 10 of unpleasant sounds, a crying baby ranks very high. It instantly makes a key part of your brain called the amygdale (杏仁孔 ) active, which, among other things, acts as a sort of radar for emotional threats. So why would babies need to cause this sort of urgent reaction? To get you to respond and fast to ensure their survival. Babies can’t fend for themselves. They are like chicks in their parents’ nest, depending on others to keep them warm, fed and safe. Like chicks, their cries signal driving necessities such as a need for food or protection from danger. But human babies can also convey a range of other needs with cries. Human babies are also highly social, and are interested in engaging in a dialogue with their caregivers. So they are equally attentive to their parents’ signals: the messages conveyed by the body language of their caregivers — how the parent smells, touches, holds, rocks, as well as their tone of voice. In relaxed moments with the parent, they soon discover how smiling at an attentive adult tends to cause a positive response in return. On the other hand, these early attempts at munication between the parent and child can be very hitandmiss. In the first few weeks, most babies cry for about two hours a d
