2 . According to the Solar Energy Industry Association, the number of solar panels installed(安装)has grown rapidly in the past decade, and it has to grow even faster to meet climate goals. But all of that growth will take up a lot of space, and though more and more people accept the concept of solar energy, few like large solar panels to be installed near them.

Solar developers want to put up panels as quickly and cheaply as possible, so they haven’t given much thought to what they put under them. Often, they’ll end up filling the area with small stones and using chemicals to control weeds. The result is that many communities, especially in farming regions, see solar farms as destroyers of the soil.

“Solar projects need to be good neighbors,” says Jordan Macknick, the head of the Innovative Site Preparation and Impact Reductions on the Environment(InSPIRE)project. “They need to be protectors of the land and contribute to the agricultural economy.” InSPIRE is investigating practical approaches to “low-impact” solar development, which focuses on establishing and operating solar farms in a way that is kinder to the land. One of the easiest low-impact solar strategies is providing habitat for pollinators(传粉昆虫).

Habitat loss, pesticide use, and climate change have caused dramatic declines in pollinator populations over the past couple of decades, which has damaged the U.S. agricultural economy. Over 28 states have passed laws related to pollinator habitat protection and pesticide use. Conservation organizations put out pollinator-friendliness guidelines for home gardens, businesses, schools, cities—and now there are guidelines for solar farms.

Over the past few years, many solar farm developers have transformed the space under their solar panels into a shelter for various kinds of pollinators, resulting in soil improvement and carbon reduction. “These pollinator-friendly solar farms can have a valuable impact on everything that’s going on in the landscape,” says Macknick.

4 . Writing an essay is a difficult process for most people. However, the process can be made easier if you learn to practice three simple techniques.

    1     When you are first trying to think of ideas for an essay, put your pen to your paper and write nonstop for ten or fifteen minutes without letting your pen leave the paper. Stay loose and free.     2     Don’t worry about grammar or spelling. Even though this technique won’t work for everyone, it helps many people get a good store of ideas to draw on.

The next technique is to write your draft rapidly without worrying about being perfect.     3     Yet, by learning to live with imperfection, you will save yourself headaches and a wastepaper basket full of crumpled (弄皱) paper. Think of your first draft as a path cut out of the jungle—as part of an exploration, not as a complete highway.

The third technique is to try printing out a triple-spaced (三倍行距) copy to allow space for revision.     4     As a result, these writers never get in the habit of crossing out chunks (大块) of their draft and writing revisions in the blank space. After you have revised your draft until it is too messy to work from anymore, you can enter your changes into your word processor.     5     The resulting blank space invites you to revise.

6 . You’ve heard that plastic is polluting the oceans — between 4.8 and 12.7 million tonnes enter ocean ecosystems every year. But does one plastic straw or cup really make a difference? Artist Benjamin Von Wong wants you to know that it does. He builds massive sculptures out of plastic garbage, forcing viewers to re-examine their relationship to single-use plastic products.

At the beginning of the year, the artist built a piece called “Strawpocalypse,” a pair of 10-foot-tall plastic waves, frozen mid-crash. Made of 168,000 plastic straws collected from several volunteer beach cleanups, the sculpture made its first appearance at the Estella Place shopping center in Ho Chi Minh City, Vietnam.

Just 9% of global plastic waste is recycled. Plastic straws are by no means the biggest source (来源) of plastic pollution, but they’ve recently come under fire because most people don’t need them to drink with and, because of their small size and weight, they cannot be recycled. Every straw that’s part of Von Wong’s artwork likely came from a drink that someone used for only a few minutes. Once the drink is gone, the straw will take centuries to disappear.

In a piece from 2018, Von Wong wanted to illustrate (说明) a specific statistic: Every 60 seconds, a truckload’s worth of plastic enters the ocean. For this work, titled “Truckload of Plastic,” Von Wong and a group of volunteers collected more than 10,000 pieces of plastic, which were then tied together to look like they’d been dumped (倾倒) from a truck all at once.

Von Wong hopes that his work will also help pressure big companies to reduce their plastic footprint.

8 . Over the past 38 years, Mr. Wang has pretended to be someone else many times,and has even learned to ________ different dialects (方言), leading to him being described as an “Oscar-winning actor”.

The 60-year-old is not an actor, but a ________ However,he is more devoted to his “________ ” than any real actor.

In the 1990s, a group of thieves often sold stolen goods with the help of some beggars. To look into the ________, Wang disguised (伪装) himself and ________ the beggars. Dirty shorts and old shoes gave him the ________ of a real beggar and his convincing dialect soon won him the ________ of the beggars.

“I often ________ them to drink alcohol. Once they were ________,they began to talk a lot,"Wang said. “I'd then ________ myself to use the toilet, ________ what the beggars said, and send the ________ to my teammates.”

Wang, who is often in ________ situations, is also a judo (柔道) master.   “As long as I get close enough, no criminal can ________ from me,” he said.

Wang's ________ won him several honors, including a National May Day Labor Medal and 11 Citations of Merit.

9 . The benefits of regular exercise are well documented but there’s a new bonus to add to the ever-growing list. New researchers found that middle-aged women who were physically fit could be nearly 90 percent less likely to develop dementia in later life, and as they did, it came on a decade later than less sporty women.

Lead researcher Dr. Helena Horder, of the University of Gothenburg in Sweden, said : "These findings are exciting because it’s possible that improving people's cardiovascular （心血管的）fitness in middle age could delay or even prevent them from developing dementia. "

For the study, 191 women with an average age of 50 took a bicycle exercise test until they were exhausted to measure their peak （最大值的） cardiovascular capacity. The average peak workload was measured at 103 watts.

A total of 40 women met the criteria for a high fitness level, or 120 watts or higher. A total of 92 women were in the medium fitness category; and 59 women were in the low fitness category, defined as a peak workload of 80 watts or less, or having their exercise tests stopped because of high blood pressure, chest pain or other cardiovascular problems.

These women were then tested for dementia six times over the following four decades. During that time, 44 of the women developed dementia. Five percent of the highly fit women developed dementia, compared to 25 percent of the women with medium fitness and 32 percent of the women with low fitness.

"However, this study does not show cause and effect between cardiovascular fitness and dementia, it only shows an association. More research is needed to see if improved fitness could have a positive effect on the risk of dementia and also to look at when during a lifetime a high fitness level is most important. " She also admitted that a relatively small number of women were studied, all of whom were form Sweden, so the results might not be applicable to other groups.
