【推荐1】Being caught in a flood is incredibly dangerous. Like many other natural disasters, floods can occur with little to no warning.     1    

● If a flood warning has been issued, seek shelter immediately,     2     It only takes six inches of moving water to knock a person of their feet, and being knocked unconscious by a fall into moving water could be fatal. Additionally, as little as one foot of flood water can sweep cars away.

● Watch out for damaged areas.     3     Avoid bridges that cross rapidly-moving water, as floodwaters can cause bridges to collapse. The soil under usual routes will be muddy and less able to support the weight of vehicles. Find alternate routes over high ground or wait for the authorities to indicate which roads are safe.

●     4     If told to evacuate (撤离), do so as quickly as possible.

● Stay inside a car trapped by fast-moving water. Only get out if the water begins to flood the car itself. then move to the roof of the vehicle.

● If trapped within a flooding building. move to the highest floor. Do not go into the attic, as it is possible to become trapped there without a way to escape. Only relocate to the roof if necessary.     5    

● Avoid power lines, as they are often damaged or knocked down during strong storms and flooding. A downed power line can cause surrounding water to become charged. leading to electrocution.

【推荐2】For many people, worrying is their life. They’re also anxious over things. They are anxious for family, friends, relatives and mankind. They fret(烦恼) about the past, the present and the future. I was once one of those people. Here’s some advice on how to stop worrying.

Let there be no crisis before its time. Don’t worry about something that’ll take place in a week, a day or even an hour. The variables( 可变因素) will be different then. If you’ve to make a decision on Friday, wait until Friday. Squash(压制) unnecessary worrying with one question. If the answer is “no”， stay in the present moment, write the thought quickly and then let it go.

Don’t let possessions possess you. Don’t let objects rule you. Don’t give them the power to spoil your day. Worrying over a problem after the fact can’t restore or bring anything back. The less you have, the less anxiety you bring into your life.

Set worry limits. If you can’t get worry under control right away, then establish limits. Set a timer or a watch alarm for 15 minutes. When the time is up, the alarm will be a tangible(切实的) reminder to let the worry go. Schedule this time when you’ve something important to do, so you’ll have to drop worry and refocus fast. Worrying is a choice, and you can choose not to do it.

Don’t control others with your worries. Worrying about loved ones wastes lots of time and opens up the door to permanent estrangement(疏远). Let people be who they are. Stop forcing others to do what will make you feel better, instead of what they want. Don’t manipulate(操纵) them into eating what you want them to eat, going where you want them to go, or doing what you want them to do under the guise(伪装) of love. Give people credit for having half a brain and knowing what’s good or bad for them. You’ll cut your worrying in half.

If you can feel the joy, congratulations!     1     Studies found that Freudenfreude contributes to kind acts, such as helping others. Celebrating the personal victories of other people can bring on more of our own.

    2     Sometimes, your loss might really sting, making Freudenfreude feel out of reach. If you were raised in a family that paired winning with self-worth, you might misread someone else’s victory as your own personal shortcoming. And factors such as mental health and overall wellbeing can also affect your ability to participate in someone else’s joy.     3    

One way to summon good feelings for others is to ask questions. You don’t need to wait for someone else’s good news to exercise Freudenfreude. Cultivate joy by inviting others to share their victories.     4     When you speak with them, be sure to maintain eye contact and listen attentively. This should motivate you to keep going and make you feel as if your efforts will pay off.

Because emotions are contagious (有感染力的), showing appreciation can also increase Freudenfroude. You can think of Freudenfreude as something you can spread when you’re experiencing personal joy.     5     Start by sharing your win, then tell the other person how you appreciate their help. Practicing gratitude is like sharing dessert: Both parties enjoy the sweetness of the moment, which enhances Freudenfreude for them both.

【推荐1】Anna Devolld likes bees, butterflies, ladybugs, hummingbirds and even bats. The 17-year-old prize winner is now helping small things to make a difference. Many TV programs and newspapers have featured her about her efforts to introduce the vital role pollinators (授粉者) play. You might say she’s been busy as a bee. She has created and helped plant over 2,000 free Pollinator Packs, each containing six different pollinator-friendly seedlings (幼苗). She also regularly visits local classrooms to teach students about pollinators and to help them plant their own Pollinator Packs.

As a teenager, Anna worried about the little things that keep our world beautiful and our orchards (果园) producing food. Anna’s solution is to increase habitats that attract pollinators and to educate the next generation about the importance of creating pollinator-friendly spaces. Her first project was creating activities and coloring books for kids to help them understand how important pollinators are to our planet. Next, she created Pollinator Packs: plants that attract bees and other pollinators to your garden. It wasn’t long before she was part of community councils encouraging the planting of pollinators in communities and roadside hallways. She now serves on her local government’s environmental advisory commission.

“One out of every three bites of food we take is dependent on pollinators,” Anna tells us. “Sadly, every one of these creatures is declining at an alarming rate.” We all can make a difference. As Anna says, “Find something you are passionate about, no matter how small, and see how you can change the world.”

So, the next time you take a bite out of a delicious apple or peach, or even better, enjoy your favorite fruit in a home-baked pie, think about all the little creatures that made it happen. Then think about Anna and how one teenage girl is making sure millions of pollinators are happy and productive.

【推荐2】The animal kingdom is dotted with species that give birth to spotted young, from deer to birds and fish. Even species that we don’t typically associate with spots, such as lions, wear the pattern as babies, only to lose it later in life.

But what purpose do these spots serve, and why do only some species seem to have them? Kiyoko Gotanda, a biologist at Brock University, said it is likely so common because spots are useful in keeping babies hidden from their enemies.

Spotted young tend to be more common in species that live in habitats with some three-dimensional structures, Gotanda noted, and less common in environments that are uniform or featureless. Indeed, baby seals born on pack ice are pure white, and develop spots only when they leave the ice for rocky beaches. But in habitats with some cover, spots function as the sunlight passing through leaves or tall grass, making an animal hard to be discovered in its background.

“It is not as overt a pattern as something like a stick insect that becomes something else entirely, which can be clearly identified. But spots do create these three-dimensional effects that help some species hide better,” said Gotanda.

In other rarer cases, spots actually help babies stand out. Young garibaldi — orange marine fish found along the coast of California and Mexico — have bright-blue spots that advertise their lowly status to highly territorial (有地盘意识的) males. As the fish grow and start to engage in the social order, their spots fade.

In fact, many species grow out of their spots, and the reasons aren’t entirely understood. According to Gotanda, patterning is typically considered more energetically costly to produce than a single, solid color. But spots don’t take a lot of energy to grow and maintain at least in the case of white spots. There must be other reasons to explain their loss, he said.
