1 . It is late autumn—millions of gardeners across the northern hemisphere, pulled on their thickest sweaters, spent hours clearing large piles of leaves and packed them into plastic bags at the end of driveways.
In the US alone, nearly 10 million tonnes of garden waste go to landfill every year. That is a large amount of effort, not just from an environmental viewpoint but from that of our aching backs, too. So where does this advice come from? Well, it largely comes from the belief that thick fallen leaves can make plants under them unable to breathe, especially shorter grass. They shut down important photosynthesis (光合作用) and get in the way of the growth of the shorter grass. However, this received wisdom has recently been questioned by researchers at Wisconsin University.
The key finding of their new research was that although clearing fallen leaves is one of the most common gardening practices, it makes very little sense. In natural ecosystems, fallen leaves help return nutrients necessary for healthy plant growth to the soil, which greatly improves soil condition. Removing leaves year after year breaks this ecological (生态的) balance. Letting some leaves stick around to cover your garden is a great way to help your grass and the local ecosystem.
They further explained that if up to 50percent of your grass lawn (草坪) is covered by fallen leaves, you might as well go back indoors and put your feet up. The advantages of this light leaf coverage far outweigh the disadvantages—the leaves will quickly break down and help next year’s lawn grow far better than if you had cleared them. Only at over 50 percent coverage do the Wisconsin researchers recommend clearing.
So why not consider leaving the leaves? Save time, carbon and effort, and in exchange get a healthier lawn from this garden waste—that seems like a pretty good deal. And how many plastic bags could be saved by simply not binning fallen leaves every year? In the US alone, about 700 million.

3 . Do you think you need to shout at yourself to force yourself to finish your homework? If so, think again.
Self-compassion is the practice of being kind and supportive to ourselves. The opposite is being self-critical and mean to ourselves when we make a mistake.
A 2017 study found people who practice self-compassion tend to handle stress better. Their bodies have less of a stress response when, for example, they meet with difficulties at work or school.
With practice, we can learn to treat ourselves with kindness and unconditional love — not tough love.
A.So how do we develop self-compassion? |
B.It may be more effective to be kind to yourself. |
C.It includes letting go of your strict self-criticism. |

9 . Liu Xiuxiang was born in a poor family. When he was 4, his father died. His mother developed mental (精神的) health problems. When he was 10, his elder brother and sisters left and never returned. To make a living, Liu collected rubbish, and in high school he worked 18 hours a day during summer vacations. However difficult it was, he never gave up his study.
In 2007, Liu failed the Gaokao. He got lost. He wondered if he should continue studying. After working in a bathhouse for about 50 days, he decided to go back to school. In 2008, he finally passed the Gaokao and went to university.
After graduation, he became a history teacher in his hometown. “I want to come back to tell the children, who are as poor and lost as I was, that education has changed my life.” Liu set a good example for them to take control of lives through education.
Now Liu gives speeches around the country. His story inspires (鼓舞) many students and encourages people to help those from poor families. Since 2012, he has helped more than 1,900 students and called on more teachers to work in poor areas to improve the quality (质量) of education.
Liu was titled “the most beautiful teacher” in 2020. His story moves us a lot.
