【推荐1】Anger may feel uncomfortable, but it’s also normal and healthy. It is an emotion built into us to signal that something needs to be dealt with. When we take notice of that signal and actually correct the problem instead of ignoring it, we’re usually much better for it.

Start by looking beyond the superficial (表面上的) trigger to your anger. Anger is often precipitated (仓促发生) by underlying feelings of fear, anxiety, disappointment and guilt. Maybe you’re extremely angry that your partner is late, but it’s really because you were afraid that he or she had a car accident in the bad weather.

It helps to take a cool-down period before explaining to someone you’re angry with how he or she rocked your boat. That will allow for the effects of the adrenaline (肾上腺素) to wear off, which in turn allows you to reflect on what’s bothering you. Do some controlled breathing or find some physical activity to take the edge off. “There’s clear evidence that exercise helps with feelings of anger,” says McIntosh.

When you’re ready to approach the other person, focus on the behaviour and why it upsets you, not the person’s characters. Avoid calling the other person names. Don’t say something bad, and don’t make generalizations (泛化), such as “You always do this!” “The idea”, says Keelan, “is to bring up your reasonable points to the other person in a manner that is most likely to get a helpful and non-defensive response. ”

If you’re on the receiving end, remember that there are benefits to acknowledging and trying to under-stand the other person’s anger. Try offering to make a change, if that seems fair to you. If you’re willing to be a partner in working through heated situations, the other person will be much more likely to bring matters up constructively in the future. In the end, you’ll both be healthier for it.

【推荐3】Stingrays are an instantly recognizable fish, with their pancake-like bodies that swim gracefully through the water. Their flat bodies allow them to sit on the bottom of the ocean, river or lake, disguising themselves to predators (食肉动物) swimming above as they hunt their prey (猎物) on the floor. Their eyes sit on the top of their body, while their mouths are on the bottom. They each have a long tail with a toxin-filled barb (充满毒素的倒钩). When they feel threatened, they can lift their barbed tails upward and injure potential predators. Most species of stingrays sport dull colors that help with disguise, though some do have more lively colors. Stingrays eat prey like worms while freshwater stingrays eat insects as well.

As those creatures move through the water, they generate bioelectric fields. Stingrays are able to detect these bioelectric fields of the animals around them using a network of special sensory organs called ampullae of Lorenzini. These organs are small, fluid-filled electrical receptors that are located near the stingray's mouth and look like tiny black holes in the animal's skin. Once they've located and captured their prey with the help of these sensory organs, stingrays use their hard teeth to break the shells of their victims, and can even chew their meal.

In 2006, Australian television personality Steve Irwin died when a stingray's barbed tail pierced his heart. Irwin was being filmed for a show called "Ocean's Deadliest" when he swam too close to a stingray. However, death from stingrays is rare. A stingray's poison is generally only deadly when its barb pierces people's neck or chest. Otherwise, contact with a stingray's. barb anywhere else on the body causes pain similar to a jellyfish (水母) sting.

Scientists also believe that stingrays have the ability to detect the Earth's magnetic fields and the orientation of electric currents generated by objects in the water. They could then use that information to navigate in the open ocean. However, this ability could potentially cause problems for the animals as offshore energy technologies like wind and wave energy become more popular, thus disturbing stingrays' ability to accurately detect their surroundings. This could influence stingrays' feeding and migration patterns.
