When I was a kid, my parents and I lived near the forest. They often told me that our family was a team that needed to work together for the household to function smoothly. There was always an abundance of work to do — cooking, cleaning, and walking dogs. I volunteered to walk our dog, Max, who had been adopted one month before. I never dared let this giant dog off the lead (牵狗绳), just in case he took off.

One morning, we were walking along in the forest when Max started pulling on the lead. At first, I was able to hold on despite the wet ground from a recent shower. But the more I tried to stop him pulling, the more it turned into a tug of war. And thanks to the slippery ground, I lost.

Pulling his lead, Max shot off like a bullet, leaving me screaming behind. I chased him but lost my footing and fell face-first into some mud. I stumbled (踉跄) to my feet, but looking ahead, I found him running back towards me. I thought he was going to stop and give me his “Sorry” look. But instead, the dog shot past me and returned after a while.

As soon as we got home, my mother immediately attended to Max with a warm towel and a doggy treat. I thought seeing me stumbling and covered in mud, I would also get a warm cup of tea and a motherly kiss. Instead, I got a very loud lecture about letting the dog loose in the forest.

I felt frustrated. It wasn’t fair that she didn’t understand how difficult it was to control Max. I fought back, “Stop lecturing me! Why is everything my fault?” With these words, I stormed into my bedroom and slammed the door shut.

In the evening, I heard my mother call Max and take him out. It wasn’t long before I heard my mother screaming and the door opening again.

I walked out of my room.

Dad stepped in, suggesting that we work together to train Max.

3 . A planet that suffers 475 C beneath a thick acid atmosphere may be the last place you'd expect alien (外星的) life in our solar system. But one NASA scientist claims that extraterrestrials (天外来客) are most likely hiding on Venus amid conditions that are unbearable for humans. The new theory was put forward by the research scientist Dr Michelle Thaller. She says that possible signs of life have already been seen within the carbon-dioxide filled atmosphere, adding that she was absolutely certain that life exists somewhere.

Venus is often described as Earth's twin due to its similar size and structure. But their conditions couldn't be further apart, as astronomers believe it would be impossible for humans to exist on Venus. Positioned 67 million miles from the Sun, Venus is the hottest planet in our solar system, suffering temperatures that can even melt lead. Its atmosphere also adds to the uninhabitable situation.

Despite this, scientists have long debated whether Venus' clouds may host microbial (微生物的) life forms that can survive. Many scientists think that photosynthesis (光合作用) is possible on the planet's surface as Venus receives enough solar energy to pass through its thick clouds.

However, Professor Dominic Papineau, a biologist at the University College of London, believes Dr Thaller's views are “difficult to realistically assume”. He explained, “For life-related chemical reactions to take place, liquid water is necessary. Hence, to find extraterrestrial life, we need to find liquid water, and to find extraterrestrial fossils requires looking for special rocks that were associated with liquid water in the past.”

This makes life on Venus today difficult to realistically assume, because its surface is too hot, although Venus might have had liquid water in its past. Even still, both Professor Papineau and Dr Thaller agree that the icy moons of our solar system could also be sites of potential microbial life. NASA suggests there are 290 “traditional moons” in our solar system-excluding 462 smaller minor planets.

6 . Gardeners who use pesticides are contributing to the decline of British songbirds, a study suggests. Scientists have urged people to stop “spraying their gardens with poisons” in order to halt bird decline and adopt instead wildlife-friendly practices. The results of the University of Sussex study, which researchers call the first of its kind, were published in the journal Science of the Total Environment.

The experiment, which surveyed 615 gardens in Britain, found 25% fewer house sparrows when glyphosate (草甘膦) was used regularly. This is an ingredient found in commonly used herbicide (除草剂) brands such as Roundup or Gallup. Slug pellets (鼻涕虫杀虫剂) also seemed to have an impact on bird sightings; in gardens where Slug pellets were used, house sparrow numbers were down by almost 40%.

Prof. Dave Goulson, of the school of life sciences at the University of Sussex, said, “The UK has 22 million gardens, which collectively could be a fantastic refuge for wildlife, but not if they are overly tidy and sprayed with poisons. We just don’t need pesticides in our gardens. Many towns around the world are now pesticide free. We should simply ban the use of these poisons in urban areas, following the example of France.” The Royal Horticultural Society, the UK’s leading gardening charity, said the use of pesticides and herbicides should be avoided if possible and they should only be used, if ever, in small and targeted applications.

The research also found that those who adopted wildlife-friendly practices such as planting native shrubs and flowers, or digging a wildlife pond, saw more birds than those who did not. Cannelle Tassin de Montaigu, a PhD researcher within the school of life sciences and an author of the study, said, “It’s encouraging to find that simple measures, such as planting native shrubs and trees and creating a pond, together with avoiding the use of pesticides, really make a measurable difference to the number of birds you will see in your garden.”

7 . In 2002, Huang Hui, a researcher of the South China Sea Institute of Oceanology, went diving near Xisha. In addition to getting an irremovable suntan (晒黑), she was left with memories of a beautiful experience with clear water and abundant colorful corals (珊瑚). However, much of the breathtaking scenery of this reef has disappeared due to climate change and human activities. All of these factors led to the decline of the coral reef in the near shore waters. “We started to cultivate corals near the Xisha Islands in 2010, and restored more than 200,000 square meters of coral reefs,” Huang said.

In 2004, when Huang was attending the 10th International Coral Reef Symposium, she found herself the only representative from the Chinese mainland. She said she felt sad but she made up her mind to strengthen communication with other countries to improve China’s level and status in coral research. She visited top coral research institutes in the US and Australia, establishing long-term cooperation with some of the world’s top coral researchers. By far, Huang has worked on coral research and protection for 22 years. Now, China is in a leading position in terms of technology and coral planting scale.

Huang believes that people’s consciousness of coral protection matters most to the sustainable development of the coral reefs. “I want to call on more people to love nature and look at the ocean in awe,” Huang said.

Partly due to her efforts, Hainan Province released a law in 2017 banning reef exploitation (开发), trading and damaging.

Huang works as a consultant for customs and frontier police on coral protection and promotes coral protection in her local schools. Huang also provides online free training for divers to teach them proper behavior in the sea to protect coral reefs.

“A group of ‘folk scientists’ have also been trained with the hope that more people can gain awareness of the significance of coral reef protection and know how to protect them,” said Huang.

“I am 50, and when I become 60, I hope that not only a coral island will be built but a sustainable development pattern will also be created,” said Huang. “The ideal state is that the coral island should be able to support fishermen and preserve the ecosystem,” she added.

10 . Several years ago, a worldwide heavy rain was predicted, but no one got prepared for what was to come. Then, some areas received over 100 mm of rain. Cars and trucks floated down the streets. Whole buildings were swept away. At least 225 people lost their lives, and millions became homeless.

The weather is always changing. Over the past few years, heavy rains have led to floods in many parts of the world. Droughts have taken place in Brazil and Australia. There have been heat waves in Europe which killed thousands. There have been more powerful hurricanes and tornadoes than ever before. In 2017 alone, the financial cost from global weather events was up to 340 billion dollars.

With more wild weather events happening, people couldn’t help asking questions: What is happening with the weather? And why? Is this natural, or our fault? The answer seems to be: a little of both. Wild weather is natural. But most scientists hold the same view that human activity has made the Earth warmer. It is this global warming that makes heat waves more likely. The higher temperatures also result in more water to go into the air, which causes heavier and more frequent rain. Many scientists also believe global warming makes hurricanes and other storms stronger.

This means we’re likely to see more wild weather. “But we don’t have to just stand there and accept it,” says scientist Michael. He and other experts say we need to stop the Earth from getting warmer. We also need to be prepared, to do things that will help save lives.
