The world uses about a thousand million(百万) tons of water a day. Water is a human right and everyone should have their share. Yet more than 700 million people around the world have trouble getting clean, safe water.
Treating wastewater is a good way to provide fresh water for us. And it also helps the environment by keeping waste out of rivers and oceans. 80% of wastewater around the world is not treated at all, and it is running into oceans. But now we have got the technology to treat and reuse the wastewater.
While 75% of our planet is covered with water, only about 2% is fresh water—that comes from rivers, lakes, ice and snow. The rest, 98% of the water, is in seas and oceans. It is too salty to drink. Then desalination businesses come in. More than 19,000 factories have been built around the world, mostly in coastal countries. They process (加工) more than 92 million tons of water every day. But the technology they use requires a lot of energy.
Scientists are working to create a less costly technology. They want to produce 20 times more clean water and make sure everyone has enough. But for now, the world still faces each day with not having enough water for everyone.
Though being a parent has never been easy, the Internet hasn't made the job any easier. Just how seriously are parents taking their role of monitoring(监控)their children's online behavior？
A new study from the Digital Future Project finds a sharp difference in parental ways of Internet supervision(监督). 70% of parents say they monitor their kids' online activity while on Facebook and other social media sites. In contrast, 30% of parents don't step in kids' online life because they trust their kids, don't know how to use social media sites or don't have time to. Such a divide is due to the fact that parents fall in multiple generations with many different types of parenting styles.
Many parents take a wide range of actions to monitor and police their teen's online behavior. Nearly six﹣in﹣ten parents say they often or sometimes check which websites their teen visits. 46% have password to log in their children's social media accounts. In order to combat unsafe websites surfing, some parents even download softwares, such as Spectorsoft, which blocks, records and alerts parents by monitoring kid's Internet use.
However, parenting expert Gwenn Schurgin O'Keeffe, CEO of a parenting website PediatricsNow.com, advises against using such software as Spectorsoft unless it's a unique situation. "You do things because you love your kids and you want to protect them ," she says, "But kids aren't these evil creatures (生物). Not trusting the online world should not be your only consideration."
With growing concerns, great efforts have been made globally to ensure Internet safety and quality for youngsters. The US government updated COPPA (the Child Online Privacy Protection Act) to increase protection for children's private information. Europe has not only given people "the right to be forgotten" on social media sites, allowing them to wipe their browsing( 浏览 ) history clean, but has also limited companies' access ( 进入 ) to personal information. "I like the idea." a user of PediatricsNow.com says, Kids and teenagers are just experimenting. Until they hurt other people, they should be free to be a kid and learn about life. "
Despite these efforts, government regulations（规章） are having a hard time keeping up as new websites pop up every day. Therefore, parents still have to step up and recognize they need to be involved in their kids' lives and find that happy medium. They have to stop being so disbelieving and give kids chances and the benefit of the doubt.
O'Keeffe advises against using softwares such as Spectorsoft because_______.
"You're going to do WHAT?" I asked my best friend, Julie, in surprise.
"I'm going to try out for the cheer-leading squad (啦啦队)," she said, eyes fixed on the ground. We had been best friends since second grade and we did everything together, but now she was going off on her own. I was sure that if she joined the cheer-leading squad, she would become best friends with someone else and I couldn't stand the thought.
"Why are you doing this? Do you really want to hang around with those girls instead of me?" I cried angrily.
"It's not about the girls," Julie said. "It's about the sport. I want to be on the squad at the high school level because they win scholarships ( 奖学金) at state competitions, and I have a better chance if I'm on the squad here," she explained. "Besides," she added, "it's not like I'm leaving the country or something."
"Goodbye," I ran away, leaving Julie standing with a sad look on her face.
The rest of that week I was unhappy, and I avoided Julie in the hall. I planned to watch the first game and take no notice of Julie. Instead, I was amazed by the enthusiasm (热情) and skill of Julie's cheering. Although she was the youngest member of the team, Julie enthusiastically led cheer after cheer. I saw how her face lit up with joy. I was stunned (目瞪口呆) as I realized that she loved the sport. Trying out for the team had nothing to do with me—maybe it was just something she wanted to do.
I walked to her, feeling ashamed (羞愧的), but Julie smiled immediately. "Hey, you were really great." I began, and then added quickly, "I'm so sorry I've been rude to you about your joining the squad."
Julie smiled and replied, "A group of us are going for ice cream. Why don't you come along?"
, but I smiled in return. As I walked toward the cheerleaders, I realized there was room in Julie's life for all of us.
English play writer Arthur Wing Pinero said, "Where there's tea, there's hope." Similarly, a Chinese saying goes that "Firewood, rice, cooking oil, salt, sauce, vinegar and tea are the seven necessary things to begin a day."
Tea is, without doubt, welcomed all over the world. Tea production around the world reached about 5.8 million tons in 2018. It has become the most popular drink in the world—after water, of course.
In order to celebrate the popular drink, the United Nations General Assembly has named May 21 International Tea Day. According to the UN, tea is much more than just a hot drink. It's a big part of many cultures around the world.
You probably know that people in China use top-grade tea to show respect when receiving important guests. Meanwhile, the British afternoon tea is an important part of that country's culture. Making Malaysia's pulled tea (拉茶) has become a kind of art form. Moroccan (摩洛哥人的) mint tea (薄荷茶) is served when getting together.
Besides its cultural importance, tea is also a medicine, used from ancient times to modern days. "Tea is cold and lowers the fire," Chinese Ming Dynasty herbalist Li Shizhen once said. The health benefits (好处) of tea are still being discovered today: preventing heart illness and cancer has been connected with drinking green tea. It's believed that the mania for healthy tea products will continue into the next ten years. People, especially women, are crazy about wonderful tea products such as moisturizers (润肤霜) and other beauty products.
Hot or cold, bagged or loose-leaf, tea is more than a drink — it's a social custom and also a magic medicine, a link to the past and a way of life.
Masks, a simple protective tool, have been used by people for a long time. They can not only prevent epidemics(时疫), but also protect us from other harmful things, such as smog and chemicals. Let's take a look.
During the1st century, lots of people in the Roman Empire worked underground in mines ( 矿井 ). Pliny the Elder (23-79), a Roman philosopher, used animal bladders ( 膀胱) to protect miners from the dust. This was the first recorded use of protective masks.
Italian artist and inventor Leonardo da Vinci (1452-1519) advised people to wear a woven (纺织的) cloth dipped (蘸) in water over their faces to protect against harmful chemicals.
In 1848, American Lewis Hassley became the first person to patent (注册专利) a protective mask for miners. In 1897, Polish-Austrian doctor Johann Von Mikulicz Radecki designed a simple mask with one layer of gauze (纱布). This was the first use of a surgical (外科的) mask.
In 1910, the pneumonic plague ( 肺鼠疫 ) broke out in Northeast China.
It was made of two layers of gauze. The mask was praised by experts around the world because it could be produced easily and cheaply.
Today, with several outbreaks of flu and the air pollution in recent years, masks have continued to develop. They can filter out (过滤掉) fine particulate matter ( 微粒物). China is now the world's largest mask producer, making about half of the world's masks.
A. For example, in 2012, when China suffered from smog, mask models such as N95 and KN90 became popular.
B. Chinese doctor Wu Liande designed a face mask called "Wu's mask".
C. These protection masks were made of chemicals.
D. He advised medical workers to wear it to prevent infection.
E. Producing masks throughout time
F. Many died of lung diseases caused by dust.
G. When was the protective mask first invented and how did it develop?
One day, a young violin player was trying to decide whether or not to continue his life in music. While he was walking, he suddenly 1 the most famous violin teacher in the world. He stopped the man and asked if he could play for him. He said to himself that he would drop his dream of music if the great 2 told him he was wasting his time.
The great teacher let him 3 . When the young man finished, he was sure he'd given his 4 performance. He stood and waited for praise (赞扬). 5 , the great teacher only shook his head and said, "You lack the fire."
The young musician was so sad that he decided to give up the violin and never play it again.
Later, he became a successful6.
Some years later, he met the great teacher again in another city. He 7 to him and said, "Sir, I stopped you on the street years ago to play the violin for you, and I just want to thank you today. To be 8, because of your coldness, I gave up my great love, and became a trader. How did you know all those years ago that I lacked the fire? Again the great teacher shook his head and said,"You didn't 9 what I said. I tell anyone who plays for me that they lack the 10 . If you had the passion (热情), you wouldn't have given up your dream."
Chinese writing is one of the world's greatest writing systems (系统). It is more (wide) used than alphabetic (字母的) writing systems. More than half of the books (write) in Chinese, including historical writings and novels, along with writings on government and law.
At the beginning, written Chinese was picture-based language. It dates back several thousand years to the use of animal bones and shells (壳) which symbols were carved ( 雕刻 ) by ancient Chinese people. Some of the ancient symbols can still be seen in (today) hanzi.
By the Shang Dynasty, these symbols had become a well-developed writing system. Over the years, the system developed into different (form), as it was a time when people were divided geographically, leading to different dialects (方言) and characters. This, however, changed under Emperor Qinshihuang of the Qin Dynasty.
Emperor Qinshihuang united ( 统一 ) the seven major states into one country where the Chinese writing system (begin) to develop in one direction. That writing system was of great importance in uniting the Chinese people and culture. And it has also become an important way connecting China's present with (it) past.
Today, Chinese writing system is still a part of Chinese culture. As China plays great role in the world, an increasing number of international students (be) beginning to appreciate ( 欣赏 ) China's culture through this (amaze) language. Written Chinese spreads Chinese culture wherever it goes.
How to Stay Safe from the Novel Coronavirus
Preventing and controlling the outbreak of the novel coronavirus (新冠肺炎) is becoming more and more important. Here are some simple precautions(预防措施) to help stay away from the virus.
The virus can be spread from person to person. The disease has an incubation period (潜伏期) of two weeks. At present, there is no special treatment for the disease caused by 2019-nCoV. So it is very important to stay away from gatherings.
Wearing medical masks in a correct way is of use to protect you from the coronavirus. You should wear masks in subways, buses, or in a supermarket. When wearing medical masks, make sure the masks can cover your mouth, nose and lower jaw completely, then compress nose clip so that mask and face are in full contact with each other.
Wash hands before eating, after toilet, coming home. When washing hands, use running water and soap, with no less than 15 seconds for cleaning hands. If you need to pick up other people's cell phones or use other people's computer keyboards, don't touch your face at once before washing hands.
If you share meals, do not use your personal chopsticks or spoons to get food from a serving bowl or plate. Place serving spoons in each dish and get what you want from the serving dishes onto your personal plates or bowls, put the serving spoon back to the main dish, and then use your personal chopsticks only to pick food from your personal plate or bowl into your mouth.
If these simple precautions are taken by everybody in your household, building, office, and school, it will be easy to prevent and control the outbreak of the novel coronavirus.
