“Look both ways before you cross the street! Look left, right and left again!” These classic childhood _______ lessons are passed on from generation to generation. Yet traffic accidents remain one of the most common _______ of injuries and deaths for children around the world.

Past studies have found that youngsters are less good at _______ road dangers than adults, but Anat Meir, a lecturer in industrial engineering and management at Ben-Gurion University of the Negeve and the Holon Institute of Technology in Israel, wanted to decide exactly which behaviors lead to accidents, with the goal of finding ways to _______ them.

To do that without putting anyone in danger, she turned to virtual reality. In 2019 Meir and her colleagues simulated (模拟) 18 streets in Israel and used an eye-tracking device to study how 46 adults and children (ranging in age from seven to 13) evaluated when it was safe to cross. Children aged seven to nine, they found, exhibited the least _______ when crossing, typically deciding to step into the virtual road with little or no hesitation, even when their field of vision was limited. “We had parents looking on who were saying, ‘Wow, I cannot believe my child just crossed there!” Meir says.” It caused them to _______ their child’s road-crossing abilities.” The older children did not perform much _______ , though for different reasons. They often stayed on the curb (路缘) for an improper amount of time— a (n) _______ that they are less able to distinguish between safe and dangerous situations than adults— and in interviews did not express an understanding of how _______ such as car speed and field of vision affect crossing safety.

Some ________ do seem to improve crossing success. In Meir’s most recent study, described in Accident Analysis & Prevention, two dozen seven- to nine-year-olds experienced 40 minutes of danger-detection training. Afterward, Meir and her colleagues ________ trainees’ and control kids’ performances in the virtual road-crossing task. The children who ________ safety instructions were significantly better at crossing than the control subjects.

Next, Meir and policy makers aim to figure out how to ________ these findings to the real world. “These results are important because you cannot find solutions without a (n) ________ of the problem,” says Joseph Kearney, a professor of computer science at the University of Iowa. “Now it’s up to people to determine how they can develop ________ programs for children and for parents about good road-crossing habits.”

文章大意:本文是一篇说明文。文章主要通过讲述一项研究阐述了做梦如何让你的学习效果得到改善。

【推荐1】It’s late in the evening: time to close the book and turn off the computer. You’re done for the day. What you may not realize, _______, is that the learning process actually continues - in your dreams.

It might sound like science fiction, but researchers are increasingly _______ the relationship between the knowledge and skills our brains absorb during the day and the fragmented, often bizarre imaginings they _______ at night. Scientists have found that dreaming about a task we’ve learned is associated with _______ performance in that activity (suggesting that there’s some truth to the popular notion that we’re “getting” a foreign language once we begin dreaming in it). What’s more, researchers are coming to recognize that dreaming is an essential part of understanding, organizing and _______ what we learn. While we sleep, research indicates, the brain replays the patterns of activity it experienced during _______ hours, allowing us to enter what one psychologist calls a neural virtual reality. A vivid example of such _______ can be seen in a video researchers made recently about sleep disorders. They taught a series of dance moves to a group of patients with conditions like sleepwalking, in which the sleeper performs the kind of physical movement that does not _______ occur during sleep. They then videotaped the _______ as they slept. Lying in bed, eyes closed, one female patient on the tape __________ the dance moves she learned earlier.

This shows that while our bodies are __________, our brains are drawing what’s important from the information and events we’ve recently encountered, then integrating that data into the vast __________ of what we already know.

In a 2010 study, researchers at Harvard Medical School reported that college students who dreamed about a computer maze(迷宫)task they had learned showed a 10-fold improvement in their __________ to find their way through the maze compared with the participants who did not dream about the task.

Robert Stick-gold, one of the Harvard researchers, suggests that studying right before bedtime or taking a nap following a study session in the afternoon might increase the __________ of dreaming about the material. Think about that as your head __________ the pillow tonight.

【推荐2】According to sociologists, there are several different ways in which a person may become recognized as a leader of a social group.

In the family, traditional cultural patterns award_________   to one or both of the parents. In other _______, such as friendship groups, one or more persons may gradually emerge as leaders, although there is no formal process of _______.In larger groups, leaders are usually chosen formally through election or recruitment.

Although leaders are often thought to be people with unusual personal ability, decades of research have failed to produce consistent _______ that there is any category of "natural leaders". It seems that there is no set of personal qualities that all leaders have _______; rather, practically any person may be recognized as a leader if the person has _______ that meet the needs of that particular group.

Research suggests that there are typically two different leadership _______ that are held by different individuals. Instrumental leadership is leadership that emphasizes the _______ of tasks by a social group. Group members look to instrumental leaders to "get things done". Expressive leadership, on the other hand, is leadership that emphasizes the _______well-beings of a social group's members. Expressive leaders are less concerned with the overall goals of the group than with providing ____________ support to group members and attempting to decrease tension and conflict among them. Instrumental leaders are likely to have a rather secondary relationship to other group members. They give others and may ____________ group members who restrict attainment of the group's goals. Expressive leaders cultivate a more ____________ or primary relationship to others in the group.They offer ____________ when someone experiences difficulties and try to____________ issues that threaten to divide the group. As the difference in these two roles suggest, expressive leaders generally receive more personal ______________ from group members; instrumental leaders, if they are successful in promoting group goals, may enjoy a more distant respect.

【推荐3】Two Newcastle scientists are setting themselves to open our eyes to the medical truth by claiming that natural sunlight may help prevent skin cancer.

Dr. Ron Laura, professor of health education at Newcastle University, and senior chemist Mr. John Ashton said their research points to a complete _______ of the accepted scientific theory. They said that sunscreen creams may help cause skin cancer, the artificial indoor light could be _______ and that a range of drugs in common use could also _______ melanoma--a type of cancer that appears as a dark spot on the skin.

The research is likely to be unwelcome in some traditional medical research circles. It is based on a new _______ that our bodies are protected from skin cancer by the regulation of a group of complex vitamins (Vitamin D) and immune process.

The sunscreens, artificial light and drugs could all unfavorably affect the production of these vitamins and increase the skin’s _______ to the sun. But Dr. Laura said natural sunlight passing through the eyes helped _______ the production of cancer protection Vitamin D.

He said recent statistics from the United States indicated that people who worked indoors all day in artificial light were more _______ to have melanomas than those who worked outdoors. Indoor workers should try to have at least one hour of _______ to direct sunlight every day, _______ in the early morning and late afternoon when ultraviolet intensively was lower, Dr. Laura said.

Sunscreens, long ________ as essential for beach lovers, could also ________ the production of Vitamin D. Laura and Ashton said sunscreens give people a ________ sense of security in thinking they are ________ from the sun’s rays.
