As countless unmade beds and unfinished homework assignments prove, kids need rules. Yet how parents make demands can powerfully influence a child’s social skills, psychologists at the University of Virginia recently found after the conclusion of a study investigating the transition from adolescence to adulthood.

Initially 184 13-year-olds filled out multiple surveys, including one to assess how often their parents employed psychologically controlling strategies, such as inducing guilt or threatening to withdraw affection. The kids rated, for example, how typical it would be for Dad to suggest that “if I really cared for him, I would not do things that caused him to worry”or for Mom to become “less friendly when I did not see things her way. ”

The researchers followed up with the subjects at ages 18 and 21, asking the young adults to bring along a close friend and, later, a romantic partner if they had one. These pairs were asked to answer hypothetical (假设的) questions that were purposefully written to inspire a difference of opinion. “We wanted to see whether they could navigate a disagreement in a healthy way, ” says study leader Barbara Oudekerk, now at the U. S. Department of Justice’s bureau of statistics.

In the October issue of Child Development, Oudekerk and her colleagues report that the 13-year-olds who had highly controlling parents struggled in friendly disagreements at age 18. They had difficulty stating their opinions in a confident, reasoned manner in comparison to the kids without controlling parents. And when they did speak up, they often failed to express themselves in warm and productive ways.

The researchers suspect that pushy parents ruin their child’s ability to learn how to argue his or her own viewpoint in other relationships. Although parents do need to set boundaries, domineering strategies imply that any disagreement will damage the bond itself. Separate findings suggest that parents who explain the reasons behind their rules and turn disagreements

into conversations leave youngsters better prepared for future arguments.

The consequences of tense or domineering relationships appear to get worse with time. This study also found that social difficulties at 18 predicted even poorer communication abilities at age 21. Psychologist Shmuel Shulman of Bar-Ilan University in Israel, who did not participate in the work, thinks these conclusions convincingly reveal how relationship patterns “carry forward” into new friendships.

58. What will happen to the teenagers with pushy parents? A. They lose social skills.

B. They have trouble presenting opinions. C. They express themselves in an aggressive way. D. They fail to inspire a difference of opinion.

59. What does the underlined word “domineering”in Paragraph 5 mean? A. alternative B. conservative C. powerful D. forceful

60. It can be inferred from the findings that parents should . A. communicate with children when setting rules B. learn new ways to establish new friendships C. seek more controlling strategies

D. help children develop abilities to follow rules

C

Exposing living tissue to subfreezing temperatures for long can cause permanent damage. Microscopic ice crystals (结晶体) cut cells and seize moisture (潮气), making donor organs unsuitable for transplantation. Thus, organs can be made cold for only a few hours ahead of a procedure. But a set of lasting new antifreeze compounds (化合物)—similar to those found in particularly hardy (耐寒的) animals—could lengthen organs’ shelf life.

Scientists at the University of Warwick in England were inspired by proteins in some species of Arctic fish, wood frogs and other organisms that prevent blood from freezing, allowing them to flourish in extreme cold. Previous research had shown these natural antifreeze molecules (分子)

could preserve rat hearts at -1.3 degrees Celsius for up to 24 hours. But these proteins are expensive to extract (提取) and highly poisonous to some species. “For a long time everyone assumed you had to make synthetic (人造的) alternatives that looked exactly like antifreeze proteins to solve this problem, ”says Matthew Gibson, a chemist at Warwick who co-authored the new research. “But we found that you can design new molecules that function like antifreeze proteins but do not necessarily look like them. ”

Most natural antifreeze molecules have a mixture of regions that either attract or repel water. Scientists do not know exactly how this process prevents ice crystal formation, but Gibson thinks it might throw water molecules into push-pull chaos that prevents them from tuning into ice. To copy this mechanism, he and his colleagues synthesized spiral-shaped molecules that were mostly water-repellent—but had iron atoms at their centers that made them hydrophilic, or water-loving. The resulting compounds were surprisingly effective at stopping ice crystals from forming. Some were also harmless to the roundworm Caenorhabditis elegans, indicating they might be safe for other animals.

“These compounds are really cool because they are not proteins—they are other types of molecules that nonetheless can do at least part of what natural antifreeze proteins do, ”says Clara do Amaral, a biologist at Mount St. Joseph University, who was not involved in the research. Gibson’s antifreeze compounds will still need to be tested in humans, however, and may be only part of a solution. “We don’t have the whole picture yet, ”do Amaral adds. “It’s not just one magical compound that helps freeze-tolerant organisms survive. It’s a whole suite of adaptations. 61. What will happen if organs are kept for a long time in temperatures below zero? A. They will have ice crystal formation inside. B. They will not suffer permanent damage. C. They will have longer shelf life. D. They will be fit for transplantation.

62. What can we learn about natural antifreeze proteins? A. They look like Gibson’s antifreeze compounds.

B. They are composed of antifreeze molecules harmless to other species. C. They are spiral-shaped and have iron atoms at their centers. D. They can be found in organisms living in freezing cold weather.

63. How are antifreeze molecules prevented from ice crystals? A. By creating compounds both water-repellent and water-loving. B. By extracting the proteins from some hardy animals. C. By making synthetic alternatives like antifreeze proteins. D. By copying spiral-shaped molecules mostly water-resistant. 64. What’s the main idea of the passage?

A. Push-pull chaos might prevent water molecules from turning into ice. B. The final solution to preserving donor organs has been found recently. C. Chemicals inspired by Arctic animals could lengthen organs’ shelf life. D. Gibson’s antifreeze compounds can do what natural antifreeze proteins do.

D

I remember my childhood summers fondly, as many of us do. Those golden days in which I would leave the house after a still sleepy, leisurely breakfast and come home only for lunch in the middle of a day spent entirely outdoors. We did not live in town and, thus, playmates were limited to siblings (兄弟姐妹) and the cousins who lived down the road.

Our backyard became the playground in which our imaginations would run wild—turning those few acres into magical forests, the creek (小溪) into a violent river and our trusty dog, Rex, into the many roles of horse, monster and any other creature that we children did not want to play. By the end of the three months of summer break we were sunburned from our hours in the sun, full of the memories of a thousand magical moments and bonded to our siblings in a way that winter’s forced hibernation (冬眠) never seemed to connect us.

Today, I live on the same acreage that I did as a child. My children have the blessing of having the same grassy patches to scratch their bare feet as they run through it, the same creek to stomp(跺脚)through, and not the same dog—but their very own energetic pup to imagine away the days with.

However, this is not the same world as it was twenty, thirty years ago. There are screens everywhere in the house to demand attention—televisions with hundreds of channels, computers with access to a thousand entertaining sites, tablets stocked with apps. There is also no longer the expectation of a stretch of an unscheduled three months. Their school friends tell competitive stories of carefully planned vacations, spending time traveling to all of the local
