1 . Playing tennis might add years to your life, according to a new study of Danish men and women. The study found that adults who frequently participate in tennis or other racket (球拍) and team sports lived longer than people who were spending a lot of time sitting down. They also lived longer than people who took part in activities such as jogging, swimming and cycling. The results raise interesting questions about the role that social interactions might play in enlarging the benefits of exercise.
No one doubts that being physically active improves our health and can extend our longevity (寿命). But whether some activities might be better than others remains in argument. One widely publicized 2017 study of more than 80,000 British men and women found that those who played racket sports like tennis tended to outlive those who jogged.
The researchers widened their inquiry and looked at a variety of sports and their associations with life. To start, they turned to the same data resource they had used for the jogging study, the Copenhagen City Heart Study. The study’s participants had all completed health exams and lengthy questionnaires about their lifestyles and whether and how often they took part in some sports common in Denmark, including cycling, swimming, running, tennis, soccer and, perhaps unexpectedly, badminton.
According to the data, cycling added an average of 3.7 years to riders’ lives, compared to sedentary Danes. Running added 3.2 years while tennis 9.7 years. These associations remained unchanged even when the researchers controlled for people’s education, socioeconomic status and age.
“Why and how some sports might add more years to people’s lives than others is impossible to know from this kind of observational study,” says Dr. James O’Keefe, a study co-author. “But we know that social support probably has unique effects on helping people get more benefits from the exercise.”
For now, people who run or ride alone might consider finding a group or partner to work out together. “Raising your heart rate is important for health,” he says. “But it looks like connecting with other people is, too.”

2 . In a world ruled by hard exercise and complex fitness programs, the simple act of walking is often ignored(忽略).
Heart Health and Weight Management
Walking is light heart exercise that helps improve heart health by increasing blood circulation(循环).
Pressure Drop and Clear Mind
Taking a relaxing walk or quick walk has been shown to give off endorphins, the body’s natural ”feel-good” materials. This leads to lower pressure levels, improved feelings, and improved mental health. Walking outdoors in nature or in a peaceful environment can provide a refreshing escape from the daily tasks.
Joint(关节)Health and Free Movement
Unlike active sports, walking is soft on the joints, making it a perfect choice for people of all ages and fitness levels.
Social Communication and Connection
| A．It helps oil joints and make them stronger. |
| B．It’s a cheap way to lead a healthier lifestyle. |
| C．So taking a walk can make your mind relaxed and fresh. |
| D．A quick walk after meals has been shown to benefit the stomach. |
| E．It cuts down the risk of heart disease and brings down blood pressure. |
| F．Walking is useful exercise that can easily be turned into a social activity. |
| G．However, walking remains one of the easiest and most useful forms of exercise. |
3 . The Rise of “China-chic”
Over past years, guochao, or “China-chic” has been gaining popularity among Chinese consumers. Guochao conveys the cultural heritage and values of China.
The idea of guochao was first borrowed from some international brands, and began to win over Chinese consumers in 2015.
In its third stage, guochao became more common in everyday life. Over the past decade, guochao has expanded from consumer goods to experiential products. As consumers are showing greater interest in cultural identity and creativity, productions like the TV program National Treasure, and the dance show Night Banquet in Tang Dynasty Palace integrate cultural and historical elements with the latest audio-visual technologies.
Nowadays, guochao is moving to the next stage. No matter how the trend evolves, Chinese people’s positive attitude toward the country’s development and their recognition of and growing confidence in national culture won’t change.
| A．The trend grew in the following years |
| B．They give the viewers a totally new experience |
| C．The next stage saw the rise of China’s native fashion trends |
| D．It also expresses national pride and confidence in a new era |
| E．The second period of guochao mainly features hi-tech sectors |
| F．Its success will rely first and foremost on gaining cultural confidence |
| G．The concept of “Made in China” was recognized as the representation of Chinese culture |
4 . Virtually, there is nothing that man cannot do. Only what he has to do is keep doing and doing without being discouraged. Success will come someday or other, though it may apparently be the conception about something that it cannot be done.
What the world-famous scientist Sir Isaac Newton had done by twelve years’ constant hard work was burnt out by his pet dog. But that could not discourage him a little.
All the great men in history have written their names in golden letters by means of perseverance.
| A．Every action has its reaction. |
| B．It is a unique precondition to success in life. |
| C．In human life, perseverance plays a very important role. |
| D．Their success will always remain as perfect examples to us. |
| E．Columbus has left us an adventurous story of perseverance. |
| F．The task that is easily done at the first attempt is undoubtedly very easy. |
| G．He was able to do it again through years of hard work and perseverance. |
5 . With roaring ships, hammering oil drill, industrial fishing and coastal construction, humans have strongly influenced the underwater soundscape (声音景观) over the past couple of hundred years — in some cases posting a threat to whales, dolphins and other ocean creatures. Until recently, underwater sound pollution had not attracted the same attention. Now, a new paper published in the journal Science lays out the impacts, demonstrating that noise pollution can be just as harmful to the ocean environment as other kinds of pollution.
Even the cracking of glaciers and any drop of rain falling on the water’s surface can be heard deep under the sea. Sea life uses sound to study their habitat, and to keep in communication with each other. They also use sound by listening to know something about their environment.
“It’s a long-lasting problem that certainly weakens the animals all the way from individuals to populations,” says lead author Carlos M. Duarte, distinguished professor at Saudi Arabia’s King Abdullah University of Science and Technology (KAUST), “We are hoping that this report will not only reveal elements of how humans impact the ocean through sound pollution, but that it will also bring the topic to the attention of policymakers who will be able to act based upon the very real solutions.”
Marine (海洋) ecologist Kirsten Thompson of the United Kingdom’s University of Exeter, who was not involved in the study, said the report could not have come at a better time. “It summarizes the fact that we are in this new phase of human-caused noise in our oceans that is having a dramatic impact on different species.” What matters most, she notes, is the fact that the paper “doesn’t just point at the problem, it shows how to solve it.”
Unlike plastic pollution or fertilizer runoff, noise pollution will not take years to fix. The moment we switch our noise off the impact disappears, Duarte says, pointing to marine life surveys conducted around April 5, 2020. Having the world use more renewable energy would lessen the need to drill for oil and gas. The international team of researchers also called for a global regulatory framework for measuring and managing ocean noise.

6 . As we sip our coffee and read the daily headlines, climate changes can seem like a distant threat. But travel a few thousands miles to the source of your caffeine fix, and the threat is all too real.
The coffee farmers are now seeing violent downpours that drown their plants in Mexico, where the climate used to be stable and mild, but the temperature now see-saws between extreme cold and heat, which greatly affects their harvest. Unfortunately, farmers across South America, Asia and Africa are also watching coffee plants decrease as droughts and downpours attack their crops as a result of global warming. The consequences of all this could soon work their way through the pipeline to your local coffee shop.
The problem arises, in part, from refinement (改进) of our taste. Two main breeds of commercial coffee Arabica and Robusta gain special reputation. The former is by far the world’s favourite, accounting for about 70% of the coffee we drink. However, the Arabica plants have been bred from a very small stock taken from the mountains of Ethiopia-giving it very little genetic diversity and making it particularly difficult to adapt to climate change. Besides, the plant grows best between a very narrow range of relatively mild temperatures (18 to 22℃ ) and needs gentle, regular rainfall. The delicate Arabica plants just can’t cope with the new and unpredictable conditions that come with global warming.
All of these paint a depressing picture for the future. Researchers predict that the land suited to farming Arabica could drop by as much as 50% by 2050. Classic coffee-producing region, such as Vietnam, India and most of Central America, will be hit particularly hard. Some of the farmers feel that the subject has almost become taboo, “We talk very little about climate. We already know how it is—and that there is nothing we can do.”
