【推荐1】Anger isn’t a pleasant feeling. Some of us bottle up the emotion, while others ______ in a wild anger. Both habits have bad effects on our bodies, our minds, and our relationships.

Anger may feel uncomfortable, but it’s also normal and healthy. “A lot of people think they have to ______ their anger,” says Patrick Keelan, a registered psychologist. “But anger is an emotion built into us to signal that something needs to be ______.” When we take notice of that signal and actually ______ the problem instead of ignoring it, we’re usually much better for it. ______, many of us have been conditioned to keep our emotions hidden. Increasingly, research is suggesting that this can have ______ effects on our health. Investigators noticed that people who make greater efforts to ______ their emotions tend to have shorter life spans. They’re more likely to die earlier from cancer, ______. When we’re angry, stress hormones (激素) are released, which can ______ a wide range of diseases, including diabetes and depression, and abnormal immune conditions.

Is it better, then, to scream and cry whenever something makes you ______? That’s the fundamental behind the “rage rooms” that have appeared in many American cities, where folks are ______ to let off their anger by violently smashing stuff in a safe environment. “The ______ is that you get the anger out of your system through ______ actions,” says Keelan. “But the research indicates that when we display our anger sharply, it can actually increase the intensity of the anger and increase the ______ of aggressive actions in the future.” It doesn’t take much imagination to predict how they can ______ your relationships with your family members, or your coworkers.

【推荐3】When you are stuck on a problem, sometimes it is best to stop thinking about it—consciously, anyway. Research has shown that taking a break or a nap can help the brain create_________to a solution. Now a new study_________on the effect of this so-called incubation（潜伏期）by using sound cues to focus the sleeping mind on a targeted problem.

When humans sleep, parts of the brain replay certain memories, strengthening and transforming them. About a decade ago researchers developed a technique, called targeted memory reactivation（TMR）, aimed at further enhancing_________memories: when a sound becomes associated with a memory and is later played during sleep, that memory gets_________. In a study published last November in Psychological Science, scientists tested whether_________the memory of a puzzle during sleep might also improve problem-solving.

About 60 participants visited the laboratory before and after a night of_________. First, they_________spatial, verbal and conceptual puzzles, with a distinct music clip repeating in the background for each, until they had worked on six puzzles they could not solve. Overnight they wore electrodes（电极）to detect slow-wave sleep, which may be important for memory enhancement—and a device played the sounds _________to three of the six unsolved puzzles. The next day, back at the lab, the participants attempted the six puzzles again.（Each repeated the experiment with a different set of puzzles the following night.） All told, the subjects solved 32 percent of the sound-stimulated puzzles compared with 21 percent of the _________puzzles.

The researchers "very bravely went for quite complex tasks that involved a lot of complex processing, and remarkably they found these really strong effects in all of their __________." says Penny Lewis, a psychologist at Cardiff University, who was not involved in the research. "These are supercool results. Now we need to go out and try to understand them by firstly replicating（复制）them and secondly trying to __________the component processes that are actually being influenced."

Beyond providing new evidence that humans restructure memories while sleeping, the research may have __________implications. "In a futuristic world, maybe TMR could help us use sleep to work on our problems," says lead author Kristin Sanders, who was a graduate student at Northwestern University during the study. Sleep-monitoring technology is increasingly accessible—and even without devices, prospective solvers can focus on important problems before __________.

Still, sleep is not __________; people need to do their homework and load their heads with the puzzle pieces involved. "I'm not going to solve cancer with this technique," Sanders says, "because I am totally __________cancer research."

【推荐3】Research confirms that performing acts of kindness and sharing thankful thoughts have many positive effects on mood and health. They are among the top five predictors of happiness. When you feel thankful for something, that's gratitude. You never get it out of ________; you are clear who or what is responsible, whether that's a loved one, a stranger, or a higher power. Gratitude is how you ________ to others when you see yourself in connection with things larger than yourself. However, this understanding of our reliance on others is becoming more ________ today. With commercial and social media, everything makes the younger generation feel that they are the ________ of the universe. If it's all about them, why thank others?

If true, there would be a disturbing ________ trend. Canadian researchers found that people who wrote thank-you letters or performed good deeds for a six-week period decreased their pain, upped their energy, and improved their mental health. And you can ________ these benefits at any age. Old people who choose to be thankful are less likely to worry about their ________ health.

Gratitude tends to be easily spread, as well. Those who are helped are more likely to pay kindness ________. One study found that when someone is thanked, it more than doubles his or her chances of being helpful again, likely because he or she enjoys feeling socially ________.

If you aren't particularly grateful now, you can learn to be. People who keep a journal of three positive things that happen to them each day ________ health-inducing thankfulness. At first, it may be difficult to recognize the good things that occur. But ________, your brain gets trained into a more appreciative mode. And in the end, the journal becomes a book of joyful ________. Gratitude training certainly comes to your aid during the dark times because a greater ________ for life is the part you focus on.

Sharing your gratefulness directly with the person you feel grateful to, the benefits of happiness ________. You don't need a scientific study to know that showing and accepting gratitude can ensure you an ________ life, a much better life than you thought.
