Regret is as common an emotion as love or fear, and it can be nearly as powerful. So, in a new paper, two researchers set about trying to find out what the typical American regrets most. In telephone surveys, Neal Rose, a psychologist and professor of marketing at the School of Management at Northwestern University, and Mike Morrison, a doctoral candidate in psychology at University of Illinois, asked 370 Americans, aged 19 to 103, to talk about their most notable regret. Participants were asked what the regret was, when it happened, whether it was a result of something they did or didn't do, and whether it was something that could still be fixed.The most commonly mentioned regret involved romance(浪漫的事)(18% ) —lost loves or unfulfilled relationships. Family regrets came in second (16% ), with people still feeling badly about being unkind to their brothers or sisters in childhood. Other frequently reported regrets involved career (13% ), education (12% ) , money(10% ) and parenting(9% ).Rose and Morrison's study, which is to be published in Social Psychological and Personality Science, is significant in that it surveyed a wide range of the American public, including people of all ages and socio-economic and educational backgrounds. Previous studies on regret have focused largely on college students, who predictably tend to have education-focused regrets, like wishing they had studied harder or a different major. The new survey shows that in the larger population, a person's “life circumstances accomplishments, shortcomings, situation in life—inject considerable fuel into the fires of regret,” the authors write.People with less education,
What you're always heard? We're eating too much salt. The average American gets about 3.4 grams of sodium every day, far more than the upper limit of 2.3 grams recommended by the USD
A. The Institute of Medicine estimates that reducing sodium intake (摄取盘)nationwide could prevent 100,000 deaths every year.The headlines now? It’s time to get tough. The New York City health department recently kicked off a national effort to cut the amount of salt in packaged and restaurant food by 25% over five years. 80% of the salt in the average person’s diet comes from those sources, not from the saltshaker（盐瓶）.But wait! The benefits of salt reduction are surprisingly murky. At least 13 studies have tried to find out what happens to people who choose to eat salty or not-so-salty food—and the results have pointed in every direction. Some studies suggest that cutting salt protects the heart: others suggest that intense salt reduction can actually increase heart problems. What's needed，Dr. Michael Alderman says, is a randomized（随机的），controlled trial, in which people are put on different diets and followed for years. It’s the only way to get a reliable answer, but it’s never been done.So what should you do? Go easy on processed foods and eat more produce. Those changes will improve your diet in a variety of ways and cut the amount of sodium you consume. If your blood pressure is high, work with your doctor to control it with drugs and lifestyle changes. If your blood pressure is healthy? At this point, there’s no convincing reason for you to count every grain.1. It is stated in Paragraph 1 that our sodium intake（ ）.2. The main sources of salt in our diet are（ ）.3.

During a trip to observe wild animals in Africa, I encountered the least brave animal on earth, the wildebeest (角马). I sat on a riverbank for three hours watching a group of thousands build（1） the courage to drink water.More than a million wildebeests（2）northward into the wetlands. It is a long, dry and difficult journey. Frequently, the only available water is the Grumeti River,（3）represents both life and death. Unlike some creatures that can take moisture（4）the grass they eat, wildebeests must drink from the river to live. The river supports other wildlife, including（5）that kill and eat other animals. Though thirsty（6）traveling, the wildebeests stand back from the water, sensing possible danger.Moving slowly toward the bank can（7）hours, as an individual wildebeest steps forward, steps back and then carefully steps forward again.

A kill is almost guaranteed.Sitting on that riverbank, I noticed that a young wildebeest finally stepped ahead and drank while the（14）adults held back. Soon, others began drinking.
