Bees seem to fly aimlessly as they search for the sugary liquid called nectar（花蜜）. But their flight plans actually do have a pattern. Flowers act as the insects' air-traffic controllers. And new research shows bees prefer flowers that aren't too flashy. 

Flowers give bees clues about how much a plant can offer. Those clues can be in the color of petals（花瓣）, in the type, in the smell or even in the electrical charge. All of these characteristics send signals to the bees, telling them whether to land or not, among which the colors play the most significant role. The insects keep track of the color of the flowers that are especially rich in nectar. They then visit more flowers of that color. 

However, color can't guarantee bees a good meal. It may change depending on the angle at which sunlight hits its petals. A yellow follower, for example, may look somewhat blue from one angle and red from another. Beverley Glover studies plants at the University of Cambridge in England. Glover and her colleagues showed that even when the color of petals looks similar, bees behave differently in searching for nectar. They started to guess that the strength of petals' iridescence（彩虹色） might be related to how bees find the petals. 

Glover and her colleagues tested their hypothesis in the lab. In their experiment, they found that bees felt confused sometimes when the petals were very iridescent and that bees had no problem finding the flowers with more nectar when the petals were not very iridescent. The team shared its new findings in the March 21 Current Biology. 

"At first sight, it's very surprising because animals can usually detect a more vivid signal more easily, "says Klaus Lunau, a biologist in Germany, who was not involved in the study. 

On the day he almost died, Kimbal Musk had food on the brain. The Internet startup talent and restaurateur had just arrived in Jackson Hole from a conference where chef Jamie Oliver had spoken about the benefits of healthy eating. This made Musk think a lot-how he might make a difference to the food industry-but beyond expanding his farm-to-table movement along with his restaurant, Musk hadn't yet broken the code. Then he went sailing down a snowy slope（坡） and fell over, breaking his neck. The left side of his body was paralyzed（不能活动的）. 

Musk eventually made a full recovery, but it involved spending two months on his back, which gave him plenty of time to come up with a plan. Since then, he has launched an initiative to put "learning gardens" in public schools across America; attracted Generation Z to the farming profession by changing shipping containers into high-tech, data-driven, year- round farms; and this year, is kicking off a new campaign to create one million at-home gardens. 

Aimed at reaching low-income families, the Million Gardens Movement was inspired by the pandemic（流行病）, as both a desire to feel more connected to nature and food insecurity have been at the forefront of so many people's lives. "We were getting a lot of inquiries about gardening from people that had never gardened before, " says Musk. "People were looking to garden for a bunch of reasons: to supplement their budget, to improve the nutritional quality of their diets, or just to cure the boredom that came with the lockdown. "

The program offers free garden kits that can be grown indoors or outdoors, and will be distributed through schools that Musk's non-profit, Big Green, has already partnered with. It also offers free courses on how to get the garden growing and fresh seeds and materials for the changing growing seasons. "I grew up in the projects when I was young, in what we now call food deserts, " says EVE, one of the many celebrities who have teamed up with the organization to encourage people to pick up a free garden. "What I love about this is that it's not difficult. We are all able to grow something."

This particular day began at seven in the morning in Casablanca(卡萨布兰卡). My friend Mike and I were going to visit Abdel, a young man we'd worked with on a volunteer project in Kenitra, an industrial city on the Moroccan (摩洛哥)coast. He'd been expecting us to arrive in Casablanca for a few days now, and since he had no telephone, he'd written down his address and name and told us to just show up-his mother and sisters were always at home.

Apparently the address he had written down was hard for foreigners like us to understand. When we got into the neighborhood, our taxi driver started asking for directions. Eventually, with the help of a policeman, we were led to a house down a winding road. Our driver went to the door and inquired. He came back saying Abdel's sister was in this house visiting friends and would come along to show us where they lived.

Soon a girl of about sixteen emerged from the house. Surprisingly, she didn't look like Abdel at all. Still, I'd seen other families where children didn't look alike, so I didn't give it too much thought. She then brought us to a yard. We waited in the yard while the sister went in and returned accompanied by her mother, sisters and brother-in-law, all of whom greeted us with cautious warmth. We were shown into the living room. The mother told us in broken French that Abdel was out, but would be home soon. We sat on low, cushioned seats, drinking sweet mint tea and eating sugar cookies, while the family members sat with us and made shy, polite conversation that frequently fell into uncomfortable silence.

An hour passed, more family members emerged from inner rooms. I was again struck by the fact that none of them looked a thing like our friend. 

After another two hours had passed with no sign of Abdel, the family insisted on serving us a meal in their kitchen next door. "Soon," was the only response I got when I inquired as to what time Abdel might come back.

Charlie Chaplin is absolutely a(remark) comedy actor, filmmaker and composer. Nevertheless, his life was anything but easy. He was born inpoor family in 1889. His parents were both poor performers, andis astonishing that Charlie was taught to sing as soon as he could speakdance as soon as he could walk. Unfortunately his father died，leaving the family even worse off. By his teens, Charlie had become one of the most popular child actors in England. 

With time going by, he got down to (make) films. His charming character made the audience laugh at a time they felt depressed. He illuminated the lives of Americans and British through two world wars and the hard years in between. Charlie Chaplin wrote, directed and produced the films he starred. In 1940, Chaplin's first sound film, The Great Dictator, was released, where he showed the(cruel) of war. Because of his outstanding performance，in 1972 he was awarded a special Oscar and remembered(permanent). To this day, Charlie Chaplin, who takes the American silent film to its peak (巅峰) with his body and facial features, (deserve) the title of the Humor Master. 

At the age of nineteen, Amy Purdy, who was an eager snowboarder, were later diagnosed as a deadly blood disease. 

Amy was given less than a 2% chance of 1 . Losing both of her legs, hearing in her left ear, Amy was forced to rethink how she would 2  adventures and achieve her dreams. Amy had to 3  how she wanted her life to go and how she would 4  the next chapter of her life. 

While change is never 5 , Amy viewed it as an opportunity. She 6 herself two things: one, she would get back on her snowboard. "I was so 7 about snowboarding, which really is what got me through my8 days. I'm grateful that I was alive. " And two: something positive would be born out of this 9 . That's been her strong determination ever since.

Amy's 10 back into daily life was hard, and she learned the countless 11 that people with disabilities face every day. The hardest thing was the12 of resources for joining in active sports which brought her the most happiness.

Besides 13  snowboarding, Amy founded a nonprofit organization supporting children and adults with disabilities who want to 14  active sports. 

"She 15 not only these athletes that are in a similar situation she has gone through, but she helps everyone believe in themselves and believe anything they put their minds to. " says Morgan Whitehouse.

Any time of the day you can commit to exercising is a good time for getting active. However, the best time for exercise is different for each person. 

Determine when you have the most energy. Do you struggle to get out of the bed in the morning or do you wake up energized and ready to go? Are you a night owl and never get to bed before midnight? Once you establish what your sleep tendencies are, you will have a better idea of when your body is most ready to exercise. You are more likely to hit the snooze (打盹) button instead of getting a workout in. 

Consider your daily schedule. When are you the busiest?Try to fit in exercise before or at least around these events. Some people would prefer to get it out of the way first thing, while others prefer to put it off until the end of the day when they are all caught up. 

Determine your exercise goals. If you are trying to develop a routine, you may want to exercise in the morning. People who exercise in the morning are more consistent. But if you are trying to improve your performance, evening exercise may be best. You may experience less tiredness, quicker reaction times, and more strength and flexibility in the evening. If you are trying to lose weight, you may want to exercise in the morning before you have eaten when your body is more likely to use fat instead of carbohydrates for energy. 

This way, you'll see how you feel and find the time that works best with your schedule. Keep an exercise log to help you evaluate each time.

A. This will give your body time to relax. 

B. Do you perform better in the morning or at night?

C. You may not feel like exercising after a long day of work. 

D. When do you tend to schedule your most important tasks?

E. Consider your lifestyle and exercise goals to find the right time. 

F. If you're not a morning person, do not schedule an early morning workout.

G. Anyway, you'd better experiment with both morning and evening workouts.

Schoolbooks typically present explorers as intrepid individuals who, for example, sail wooden ships to new lands or climb Mt. Qomolangma alone. But today most explorers who are making fundamental discoveries are scientists. And whether the frontiers are tiny, like the human genome, or massive, like our deepest oceans, we still have much left to learn about planet Earth. 

Exploration is science in its most basic form — asking questions of the natural world and, we hope, using the answers for the betterment of everything on Earth. 

Exploration has great value. It inspires us, widens our knowledge and gives us hope for a better future. And the practical payoffs can even be lifesaving. Scientists who spent decades exploring what was in the atmosphere found that over time the concentration of carbon dioxide was rising. Without that discovery, we humans would now be living like the proverbial frog in a pot of gradually heating water, unsure why the environment around us is changing, and slowly boiling to death. 

The human drive to overcome challenges is an essential aspect of the human drive to explore, which, in most cases, spurs innovation. Early human submersibles that reached the bottom of the deepest ocean trenches(海沟) made the trip just once, stressed by the enormous pressures there. But eventually a more stress-resistant deep–submergence vehicle, the Limiting Factor, allowed investor and undersea explorer Victor Vescovo to reach trench bottoms numerous times. Now there are roughly 4,000 autonomous Argo floats across the world's oceans that dive down to 2,000 feet and resurface every 10 days. The Argo group will also deploy(部署) dozens of sensors every year that will gather biological and chemical data, leading to new observations about marine life.

Ocean research groups also have made it a priority to openly share their discoveries and data with the public and to inspire the next generation of young scientists. Anyone can go along for the ride — we can all be explorers. Maybe one day you'll explore the Great Barrier Reef, the desert, or a rain-forest canopy(树冠).

Captain James T. Kirk began each episode of the original Star Trek television series by saying, "Space, the final frontier(前沿). " Not necessarily. We still have plenty to discover right here on Earth, and we eagerly await surprises from the newest worlds we find.

Feel exhausted after a party? Rather see one close friend than a group of acquaintances? Enjoy your own company? In our world, that makes you an introvert (内向的人). However, there's another possible explanation — vertical attachment. If you are closer to your parents and family members than to your peers, you are vertically attached, which means you rely more on family for comfort.

If you are closer to your peers, then you are peer attached. We live in a peer-oriented world. We believe that having lots of friends means that we are well-adjusted. We put our kids in playgroups and daycare for peer interaction. We expect teenagers to want to hang out with their friends, thinking it is the natural way of things. 

Result? Generations often feel worlds apart. We use different language, dress, and technology apps. Even if multiple generations are invited to the same party, the kids go to the basement playroom while the parents stay upstairs. 

Vertically-attached individuals can feel out of place in this context, demonstrating the traces of introversion. Will they be exhausted after a party with same-aged acquaintances? Absolutely. Would they rather spend time with one close friend? Sure. Do they enjoy alone time? Yes, more than they enjoy time fitting in with peers. 

It's normal that many people need alone time to recharge. However, vertically-attached people often label themselves as introverted. They feel insecure that others have more friends and live richer lives. They claim that their family attachments arise from their loved ones being stuck with them.

If you feel these insecurities, know that there is nothing wrong with you, and you are not missing out on anything. Your attachment style is just different from the culture where you live. Have confidence in the strength of the relationships you have, whether it is with a mom who feels more like a best friend, or a grandmother with whom you can share anything. They are meaningful, enriching relationships, even if they look different from the cultural norm.
