【推荐1】Hobbies are considered leisure activities people engage in to relax and feel less stressed. There are various physical and non-physical leisure activities. Physical activities include walking, running, jogging, hiking, gymnastics, fishing, skating, swimming, basketball, boxing, volleyball, etc.     1     These not only are usually relaxing but also provide skill advancement.

Everyone needs a break from responsibilities, and chores!     2     They provide an amazing chance to have fun during selective leisure time. Not only are you able to enjoy recreational pastime, but hobbies allow you to develop skills and values that can last a lifetime. Hobbies might also help you feel more present in the moment.

    3     It’s actually best to engage in multiple hobbies throughout the week. Explore different types of hobbies to not only find what fits you best but also exceed all benefits hobbies can offer. However, try not to take on so many that you begin to find them taxing(伤脑筋的)or tiring. The entire purpose of hobbies is to relax and enjoy yourself.     4     Therefore, if you’re trying out a new hobby, remember to balance your time. Make a schedule of which activities you want to take part in throughout the week.     5     For example, if you like to work up a sweat, then activities such as yoga, dancing, walking, or running might be great hobbies for you to try. And if you enjoy staying in or already have a physically demanding job, you might join a book club, go to an art class, or learn how to cook a new recipe.

Some people have been hit particularly hard, including the elderly, parents occupied with work and child care, and students who have lots of homework.     1    .

New research suggests that volunteers aren’t just helping the communities.     2    . Compared to people who didn’t volunteer, people who had volunteered were more satisfied with their lives and rated their overall health as better. Additionally, people who volunteered more frequently experienced greater benefits.

    3    , the researchers compared it to the effects of people’s income. For a participant earning an average middle-class salary, volunteering was essentially “worth” approximately $1, 100 per year. That means volunteering would make someone as happy as having an extra $1, 100.

Why does volunteering support our mental health? Firstly, volunteering appears to be really rewarding-when we help others, we tend to experience what researchers call a “warm glow. ” Secondly, volunteering is likely to help boost our sense of social connection, which is particularly true for older adults.     4    . You are doing something new and you will gain new skills in other aspects of life, and the young adults can try out leadership opportunities in various practices.

    5    . So, if you’ve been feeling upset or out of sorts lately, join some volunteering activities, which will definitely bring you a sense of control and comfort no matter the frequency or the type of work.

On a fine day, it may feel unnecessary to put a camping tarp (防水油布)under your tent, or to put the top flysheet on.     2     . Flysheets help to avoid rain into the tent’s inner layer, so it’s important to fix them properly.

Lightweight sleeping bags are usually only appropriate for summer camping.     3     . Winter-weight sleeping bags are often very thick or heavy and are usually coly appropriate if you’re going camping in temperatures that drop below freezing overnight.

Whatever the season, you’re likely to get sweaty when walking in the daytime. Aside from it feeling unpleasant to sleep in clothes that are dirty and sweaty, it`s also potentially dangerous to go to bed wearing damp clothes. Keep a separate set of sleeping clothes when you’re backpacking so that you can protect yourself from getting wet at all costs.

Separating your tent with carpets or mats is a good way of keeping your tent warm. This is an especially good idea if you don’t have the world’s greatest sleeping bag.     5     .

【推荐1】The Centers for Disease Control and Prevention reported recently that diseases from mosquito, flea and tick bites tripled in the US between 2004 and 2016, with more than 640,000 cases seen during that period of time. Maine alone saw a 20-fold increase in cases of the tick-borne (蜱传播的) illness Lyme disease. The danger showed no sign of abating this year, with ticks crawling into Mainers’ lives as early as May.

Their early arrival was largely a product of warmer temperatures in the region. It is perhaps for this reason that Lyme disease-once a regional problem largely confined to New England-has now been discovered in all 50 states. Warm weather-loving ticks and Lyme disease are just the examples of how our rapidly-heating planet is destroying our health.

Climate change’s most visible symptoms are the natural disasters we’ve seen so often in recent years. When a disaster strikes, the most immediate threat to health is, of course, the danger posed by the event itself. During the 2017 wildfires in California and Oregon, for example, many living near the smoke reported respiratory distress (呼吸窘迫) and other problems because of breathing in the dangerous smoke. But this initial damage is often just a prologue (序幕) to the damage these disasters can have on our health-damage that unfolds over the course of weeks, months or even years.

Take standing flood water for example. It’s a ripe breeding ground for mosquitoes and bacteria and can pose a serious threat in the period following a major storm. Climate change’s impact is combined with the destruction of the basic construction-like power grids and drinking water delivery systems-and the loss of core services-like health care and waste disposal. It can both create new health challenges and complicate the treatment of existing ones.

Climate change can lead to storms and fires, fever and smoke, and the mental and physical health challenges that characterize the long aftermath of disasters. It is through these damages that climate change has gotten under our skin, into our lungs and weighed on our minds to the hurt of our well-being.

【推荐3】Honeybees can’t swim, and when their wings get wet, they can’t fly. But one study shows that honeybees do have another, less obvious choice to save them from death in the water: surfing.

The discovery began with a lucky accident. When research engineer Chris Roh passed by Caltech’s Millikan Pond, he saw a honeybee resting in the water, and since it was midday, the honeybee’s shadow (影子) fell directly on the bottom of the pond. However, what really caught his eye was the waves created by the honeybee’s wings, as the waves from one wing crashed with those from the other wing.

Roh brought honeybees to the lab, where he recreated the conditions, he saw at Mfillikan Pond. He placed a bee in a pan of still water and then shone filtered (过滤的) light from above to pretend it was the midday sun. He did this with 33 bees, but only for a few minutes one single bee at a time, and then gave each bee time to recover.

While water prevents a bee from flying by clinging (紧附) to its wings, the same condition obviously provides another way for the bee to escape. The bee pulls water with its wings, creating waves that can push it forward.

But there are some limitations. Obviously, the bees can’t produce enough force to get them out of the water. However, the wave can push them forward enough to the edge of the water, where they can then climb out and fly away. This behavior is more tiring than flying, and Roh guesses the bees can only hold it for about 10 minutes before using up their strength, so the chances to get out may, be limited.

“This behavior has never been recorded in other insects,” Roh added. This study focused on honeybees, but future studies could investigate whether it is also used by other bee groups or possibly even by other winged insects.
