Organic(不使用化肥的) farmers produce food with least help from pesticides(杀虫剂),but in limiting the use of chemicals on their own land, they may be unknowingly causing an increase in pesticide use over their neighbour's fence(栅栏).

Ashley Larsen at the University of California and her colleagues looked into land-use and pesticide data across 14,000 fields in Kern County, California. The researchers found that when organic farmland is surrounded by conventional (传统的) agriculture, neighbouring farmers seem to increase their pest í cide use, with a 10% rise in organic cropland being linked to a 0.3% increase in total pesticide use on conventional fields. Most of this is driven by greater use of pesticides, the researchers found.

This may be because more insects tend to live on organic land and spill over into neighbouring fields, causing conventional farmers there to increase pesticide use, according to larsen. The effect appears strongest when neighbouring fields are within 2. 5 kilometres of the organic "focal field" .

However, the researchers noted that the presence of organic farmland is linked to a reduction in pesticide use on neighbouring organic fields, with a 10% increase in the area of nearby organic cropland being related to a 3% decrease in total pesticide use on organic focal fields. This may be because the larger area of organic farmland allows for a bigger and more stable(稳定的) community of beneficial insects.

When organic agriculture makes up a high rate of farmland———perhaps 20% or more——net pesticide use decreases no matter where the organic fields are sited, say the researchers. But when small areas of organic farmland—like in Kern County, where about 5.5% of agricultural land is organic--evenly spread through the landscape, net pesticide use may in fact be higher than when no organic farming is present.

However, this impact can be softened by bunching up organic farmland. Larsen said, "It might be worth considering how to encourage the concentration of new organic fields to basically take full advantage of its pest control benefits and limit the costs of being organic to conventional growers."

'One of the greatest musical geniuses (天才) of our time is Itzhak Perlman—but carrying the weight of that title as a child wasn't easy. The violinist describes his early musical education as hell, with pressure from his teacher and his parents. They required him to do as they said. When Perlman got to Juilliard School, he was shocked when he was encouraged by his new teacher t ò be more expressive and self-reflective. Now, in the program for young musicians that he runs with his wife Toby, he uses a similar style with his own students, encouraging each to become the best version of themselves.

It's easy for us to regard Perlman's early experience as a misguided approach of the past.Yet, in effect, this is exactly what we do when we label(贴标签) some as "gifted". Whether it happens at school, at home, or elsewhere, research has proven that singling out a chosen few has negative influences on us all.

When we single out those we believe to be exceptional, we create a culture of genius. This is an environment where star performers get the most resources and where the basic bē lief is the fixed mindset: Some have it, and some don't. Once you single out children as exceptional, you put them on a pedestal(受人尊敬的地位)—one they often become afraid of falling off. Additionally, those labeled as gifted tend to possess a narrow set of skills. This affects their long-term development.

In contrast, in cultures of growth, the central belief is the growth mindset—a belief in universal potential(普遍的潜能): Everyone has the ability to grow, learn, and contribute from wherever they are. In cultures of growth, everyone receives the necessary resources and instruction to develop, Cultures of growth nurture(培养) everyone based on their needs and abilities.

We all have the power to create cultures of growth in our families, schools, and workplaces by holding the belief that everyone can learn and contribute, and by supporting one another on the path to success. Because we know that it's in cultures of growth where the real genius lies.

That Saturday was significant only in hindsight(事后聪明). It was 6November2010, and it was a training day for my school's new journalism team. The teacher advised me to start a blog to get into writing. Bored and in need of a project, I set up a Blogger account at home.

As I typed post after badly written post in the months that followed, my computer was filled with the beginning of novels, half-finished song lyrics(歌词), and the odd poem—things I'd Started in k a fit of teenage enthusiasm only to be let down by my lack of creativity. But somehow writing about the news and myself seemed easier. I loved finding just the right phrase to express my feelings.

It had, to say the least, not been a good year. I became increasingly lonely as my peers(同龄人) went to parties while my disability kept me at home after school. My care r of five years had just walked out of my life with no real explanation as to why. This threw me info front of the fact that I couldn't just ignore the reality of being disabled and hope everything would be fine. I was stuck trying to find a new way to approach life.

There were so many things I couldn't do——or, at least, I told myself I couldn't. But there was something that required only a computer and an idea, something that my disability couldn't make difficult as it did to everything else: I could write. After many painful years of shyness, I found I had a voice--clear,confident and mine. It wasn't long until my mind was made up: I was going to be a journalist.

Seven years later, I am. I've never been so happy that my younger self listened to the advice that turned out to matter most. Though I don't publish much on my blog these days, I still go back to it when I have something I desperately(极度地) need to say. Because no matter how long it's been, my blog still gives me the same thing it did on that very first day: somewhere to go, all of my own.

In a small town located in the mountains, there was a young boy named Owen. He was crazy about basketball more than anything else in the world. He would spend hours every day practicing his dribbling(运球), shooting and passing. He dreamed of one day winning games on a team.

Owen's town had a small basketball court that was often empty. Owen would go there every day after school to practice. One day, as he was shooting hoops (投篮), he heard a voice behind him, "Hey, kid! You're pretty good!"

Owen turned around to see a tall man with a friendly smile. The man introduced himself as Coach Johnson and asked Owen if he wanted to join his basketball team. The team was made up of kids from all over the town, and they practiced every day after school.

Owen was overjoyed because he had never played on a team before. He wanted to start and win games. Owen quickly became the star player of the team.

However, the team never won a game. "I had trained so hard and performed excellently, but we were always losing! Jack should have run much faster towards me and Kris should have passed the ball to me!" Owen kept complaining to the coach.

The complaint seemed understandable! Owen was admired by his teammates because he was fast and had incredible shots. However, Johnson knew Owen lacked something important. He told Owen to learn to play with his teammates as a team instead of just focusing on himself. Owen didn't quite understand that at first and insisted he just needed to practice harder to win games.

However, disaster struck. Owen injured his ankle one day and had to sit out for several weeks, which let him fall into anxiety. He felt his dream was slipping away.

During his recovery at home, Owen refused to see anyone on the team, except his coach. Johnson handed Owen a phone downloaded with some videos about the best basketball teams and some cards from Owen's teammates.

The Fahai Temple, located at the southern foot of Cuiwei Mountain in the western part of Beijing, houses Ming Dynasty frescoes(湿壁画) dating back nearly 600 years.

The temple, which (build) in 1439 during the time of Zhengtong in Ming Dynasty, is known as one of the three major fresco (site) in China, together with Dunhuang of Gansu province and Yongle Palace in Yuncheng, Shanxi province. These impressive frescoes originating from the royal family were completed by 15 artists, used traditional techniques that led to the frescoes with vivid effect.

Despite the brilliance of this Ming Dynasty fresco art, it did not maintain (it) splendor throughout history. With the fall of dynasty, the golden time of the art came to a sudden end.

Today, a brand-new art center has been set up at the foot of the mountain, where visitors can immerse(使沉浸) themselves in a digitalized journey of discovery. "By (employ) modern technology, we can bring the (value) frescoes to life," says Liu Xiaobo charge of the Fahai Temple Mural Art Center.

(current), the original frescoes are being protected and opened to the public in a controlled manner.

Visits are arranged by appointment, with each viewing session limited to about 20 minutes. Visitors can only use cold light sources throughout the visit, allowing the original frescoes (rest) more.

Most of you may want your kids to stay away from social media because it can bring harm. But social media can have a positive effect on them, like helping them learn how to communicate with others, improve relationships and deal with somebody who isn't being kind to them.. If you decide to let your kids use social media, follow a few tips to help them better explore the social media world.

Talk to your kids. From the beginning, it's important to have an open and honest conversation with your kids about what social media is and what it can be used for. Ask why they're interested in having an account on a particular platform and what they want to use it for..

Limit screen time. The American Academy of Pediatrics (JL科) recommends limiting screen time to two hours a day for kids., but parents should also focus on a bigger picture making sure your kids are getting enough physical activity and face-to-face interactions.

Monitor their usage., whether that's scrolling through(滚动浏览) their tablet or phone or using a social media monitoring tool. "See what apps are there and familiarize yourself with those," psychologist Kate Eshleman says. "Ask yourself if this tool is going to fit your goal."

. Easier said than done, right? But practicing safe and healthy social media behaviors in front of your kids really matters. "It's much harder for kids to understand the potential dangers or risks of social media when parents engage in the same behaviors themselves," Eshleman says.

A. Be a role model

B. That's a good guideline

C. Check on what your kids are consuming

D. Put a ban on improper social media behaviors

E. As they start venturing into the world of social media, keep talking

F. Parents should know how to interact with their kids on social media

G. Therefore, no social media at all might not be the best solution for your kids

As humans, we might believe that we are the smartest and perhaps the only creatures in the world capable of having feelings and subjective experience, but is this really the case? A new study finds that bumblebees(大黄蜂) like to play. They like to roll around small wooden balls with no apparent motivation - it likely makes them feel good.

Previous evidence suggests that bees have positive and negative emotion-like states usually when they are given food rewards to test their abilities. However, in an experiment of the new study, some researchers had trained bumblebees to roll balls into a target in exchange for a sweet treat. They noticed that sometimes bumblebees would roll the balls outside of the experiment area for no reward.

This observation gave rise to new questions: What are they doing? Why? Is this random or intentional?

To answer these questions, the researchers set up more experiments. In the latest experiment, they watched 45 bumblebees in an enclosed area where they could walk through a clear path to reach a feeding area, or they could go off the path into areas with wooden balls. They found the bumblebees went out of their way to sit on the balls or push them. Each rolled the balls between one and 117 times during the experiment.

The researchers say that because they did it repeatedly with no food payoff, it suggests that the ball rolling was rewarding.

"The behavior was voluntary," says study first-author Samadi Galpayage. "Bees have a reputation for being hard workers, but the prospect of bees engaging in something like play is really novel and exciting because it shows that bees may experience pleasure and don't only carry out duties that are strictly essential for immediate survival. "

Galpayage adds, "Personally, I find this behavior fascinating because it tells us that bumblebees, like many other animals, are more than little robotic beings, but have a richer behavior and life than we would have previously thought."
