The 2016 Rio Olympic Games have come to an end. Without doubt, many Chinese sports fans sat in front of the TV and cheered our athletes on, hoping that they would get as many gold medals as possible.
But sometimes our desire for gold medals can result in the sadness of failure. When Liu Xiang, China’s track hero, pulled out of the Beijing Olympics due to injury, he greatly disappointed many Chinese sports fans.
But things are different now. In the 2016 Rio Olympic Games, we saw a healthier Chinese attitude towards the sports people, fully in line with the Olympic spirit.
China didn’t win any gold medals on the first day. But, instead of criticizing(批评) the athletes who failed to win, most of the fans were happy with their efforts. “Looking at the results in the right way when an athlete misses out on gold shows the maturity(成熟) of a person, and is also a challenge for a country to face up to in the process of development,” commented CRI.
Swimmer Fu Yuanhui won fans’ hearts, even if she only won the third place in the 100m backstroke final. Her fans on her Sina Weibo have increased 100,000 to over 6 million. Many sports fans appreciated her straightforward character and attitude towards competitions.
“The warm support from Internet users shows that public attitude towards competitive sports and the Olympics has gotten to a higher level”, said an article in the People’s Daily.

Scientists blame greenhouse gases for being a major cause of climate change around the world. This is because greenhouse gases trap heat in the atmosphere and make the planet warmer.
Now, a team of researchers has announced a successful experiment that turned carbon dioxide into useful liquid fuel. The researchers created a device, called a reactor, which changes bon dioxide into a pure form of formic acid(甲酸). Formic acid is a substance (物质) found in ants and some other insects, as well as in many plants. It is used as an antibacterial material and in the processing of some kinds of clothing.
Haotian Wang led the research team. He said in a statement that the results of the experiment were important because formic acid is a major carrier of energy. So, the substance can provide a way to reuse carbon dioxide and prevent it from being released into the atmosphere. “It’s a fuel-cell fuel that can generate electricity and send out carbon dioxide which you can grab and recycle again,” Wang said.
“Other methods for turning carbon dioxide into formic acid require intense purification processes,” Wang said. Such methods are very costly and require a lot of energy. The Rice University team said it was able to reduce the number of steps in the traditional process to create a low-cost, energy-saving method.
The researchers reported the reactor device performed with a conversion rate (转化率) of 42 percent. This means that nearly half of the electrical energy can be stored in formic acid as liquid fuel. The team said the reactor was able to create formic acid continuously for 100 hours with little degradation (退化) of the device’s parts.
Wang said the reactor could easily be used to produce other high-value products, including alcohol-based fuels. The researchers noted that the technology could also be a big help in solving another major energy problem—how to store large amounts of power in small places.

Australia and New Zealand’s health organizations have given their advice on when to use sunscreen (防晒霜), suggesting Australians apply it every day to avoid bad health effects.
A Sunscreen Summit took place in the Australian State of Queensland. During the summit, representatives from some of Australia’s leading research, medical and public health organizations examined the evidence on sunscreen use and determined that in most parts of the country it is beneficial to apply sunscreen every day.
“Up until now, public health organizations have recommended applying sunscreen ahead of planned outdoor activities but haven t recommended applying it every day as part of a morning routine (惯例),” professor Rachel Neale from QIMR Berghofer Medical Research Institute said. “In recent years, it has become clear that the DNA damage causes skin cancer and melanoma(黑色素瘤), which is caused by repeated small exposure to sunlight over a period of time,” Neale said. “In Australia, we get a lot of sun exposure from everyday activities such as alking to the bus stop or train station,” Neale said.
A study showed that one in two Australians believed it was unhealthy and potentially dangerous to use sunscreen every day. However, Terry Slevin from the Public Health Association of Australia says it is wrong. “There is consistent and compelling evidence that sunscreens are safe,” Slevin said. “Importantly, medical trials have found that people who use sunscreen daily have the same levels of vitamin d as those who don’t,” Slevin added.
Australia has one of the highest rates of skin cancer in the world which is made worse by the country’s close to Antarctica where there is a hole in the ozone layer (臭氧层), letting in higher numbers of UV rays.

When Faith Wanjiku graduated from the Technical University of Kenya last year, she immediately enrolled (注册) at the Confucius Institute in Kenyatta University. She wanted to learn Chinese, as she believed that it would help her land a good job.
She has just completed the hanyu Shuiping Kaoshi (HSK) 3 exam. HSK is a test of Chinese language level for non-native speakers, organized by the Confucius Institute Headquarters.
However, this level isn’t enough for Wanjiku, who plans to pass HSK 6. She wanted to increase her level of Chinese and improve her spoken Chinese. And Wanjiku isn’t alone. The number of people taking the HSK reached 6.8 million in 2018 and went up 4.6 percent from a year earlier, the Ministry of Education said on May 31.
Chinese is becoming an increasingly popular choice of language to study around the world. Currently, middle school students in Russia can take Chinese as an elective language test in the country’s national college entrance exam, Sputnik News reported.
In May, Zambia became the fourth country in Africa-after Kenya, Uganda and South Africa—to introduce Chinese language to its schools.
And many English-speaking countries have shown an interest in allowing their students to learn Chinese. The US government announced the launch of “1 Million Strong” in 2015, a plan that aims to bring the total number of learners of Chinese to l million by 2020.
Behind the growing popularity of Chinese language learning is the international community’s positive attitude toward Chinas future development, as well as the people’s longing to learn about Chinese civilization and culture.
Indeed, it’s as the former president of South Africa Nelson Mandela put it, “if you talk to a man in a language he understands, that goes to his head. If you talk to him in his own language, that goes to his heart.”

For a herder (放牧人) in Africa, the hardest part of the job is searching for cattle lost in the bush. But for Andrew, a herder at a farm in Zimbabwe, it's not a problem. Once he spots Toro, he knows the rest of the herd is nearby. That’s because Toro isn’t an ordinary member of the herd. He's a giraffe. In hot weather, cattle rest in the shade under his belly. And because of his height, Toro can spot lions long before they come close to the herd.
Toro's unusual situation came about after his mother was killed by lions. Toro survived the attack, but he was left with no one to protect him or give him milk. About two days later, some herders spotted and rescued him. With the permission of the Department of Wildlife, the herders moved Toro to Andrew's farm. Since giraffes and cattle are both plant-eating animals that live in groups, their behaviors are much the same. Toro was accepted into the herd and wandered among the cattle as they ate grass.
Toro doesn't always behave like the other members of his new herd. Like many kinds of animals, cattle compete for dominance (支配). Standing more than 13 feet tall, Toro is more than three times taller than the biggest bull, But Toro never tries to be ''the boss. ''He is very used to their company, '' Andrew said. When the herd enters the kraal (家畜栏), the cows and bulls push each other. ''But thanks to his height, Toro does not need to join the mess, '' said Andrew.
When asked if Toro would ever be returned to the wild, Munetsi, an officer of the Department of Wildlife said no. ''In the wild, he would find it difficult to be accepted into another herd or defend himself from predators (猎食者),'' he added. ''He seems very much at home and is respected by the cattle.''

3.What will happen to Toro according to Munetsi?
