1 . Binge-watching (刷剧) is when a person watches more than one episode of a show in a row. With developments in the speed and connectivity of the Internet, increases in technology and the rise of on-demand entertainment companies, people can now have their favorite shows stream (流播) directly to their television at their convenience.

This behavior is nothing new. In fact, binge-watching has been officially listed in dictionaries since 2015. The entertainment companies recognize this behavior and many take steps to encourage it. Often, instead of releasing each episode on a week-by-week basis, an entire series will become available concurrently. Once the episode finishes, many platforms will display pop-ups with “you might like” suggestions, or will automatically play the next episode.

However, recent research suggests that out of the more than half of British adults who watch more than one episode of a show back-to-back (一集接一集地), almost a third have admitted missing sleep or becoming tired as a result; and 25% have neglected their household chores (家务活). Next we’ll be missing work!

Bingeing has other connections — binge eating, binge drinking and binge smoking. All of them are often associated with a lack of control and a possible route to addiction. Lindsey Fussell, consumer group director, said, “The days of waiting a week for the next episode are largely gone, with people finding it hard to resist (抗拒) watching multiple episodes around the house or on the move.” If people find binge-watching hard to resist, are we witnessing the birth of a new type of addiction?

The countless number of information and entertainment that television and online media can bring us is, many would say, a good thing. However, when the activity begins to bleed into other areas, causing us to stop functioning, then it becomes a problem. So, what’s the answer? Moderation! Neither a tiny amount, nor too much. After all, as the old proverb says, “A little of what you fancy does you good.”

4 . Running is often tiring and a lot of hard work, but nothing beats the feeling you get after finishing a long workout around the track.

But while it’s long been believed that endorphins (内啡肽) —chemicals in the body that cause happiness—are behind the so-called “runner’s high”, a study suggested that there may be more to this phenomenon than we previously knew.

According to a recent study published by a group of scientists from several German universities, a group of chemicals called endocannabinoids (内源性大麻素) may actually be responsible for this familiar great feeling.

To test this theory, the scientists turned to mice. Both mice and humans release high levels of endorphins and endocannabinoids after exercise. After exercising on running wheels, the mice seemed happy and relaxed and displayed no signs of anxiety. But after being given a drug to block their endorphins, the mice’s behavior didn’t seem to change. However, when their endocannabinoids were blocked with a different drug, their runners’ high symptoms seemed to fade.

“The long-held notion of endorphins being responsible for the runner’s high is false. Endorphins are effective pain relievers, but only when it comes to the pain in your body and muscles you feel after working out,” Patrick Lucas Austin wrote on science blog Lifchacker.

Similar studies are yet to be carried out on humans, but it’s already known that exercise is a highly effective way to get rid of stress or anxiety. The UK’s National Health Service even prescribes (开药 方) exercise to patients who are suffering from depression. “Being depressed can leave you feeling low in energy, which might put you off being more active. Regular exercise can improve your mood if you have depression, and its especially useful for people with mild to moderate (中等的) depression,” it wrote on its website.

It seems like nothing can beat that feeling we get after a good workout, even if we don’t fully understand where it comes from. At least if we’re feeling down, we know that all we have to do is to put on our running shoes.

China’s “Cultural and Natural Heritage Day" falls on the second Saturday of June every year. Many celebrations are held, and all cultural relic protection sites are _______ to open free to the public on the day. There is no_________ that various celebrating activities across the country will arouse public _________of the importance of cultural heritage protection and _________the young people to love the fine_________ culture of the motherland.

China faces a heavy task in protecting and rescuing its cultural_______. We need to seriously consider the _________ of the lack of awareness about cultural heritage protection. Thus, Heritage Education is one of our main approaches. People cannot _________ value cultural heritage if they do not know why it is important or how to protect it. Over the past seven years, CHP has _________ over a hundred educational __________ to various groups, such as schools, government offices, and the general public. Many people have attended CHP seminars. Typically, each seminar lasts two or three hours and __________ of an informative presentation, __________by a longer question-and-answer session and discussion. Attendees with __________ knowledge of cultural heritage __________ it to be just the Forbidden City and the Great Wall. People often think that the duty only __________ to the government. So “Cultural and Natural Heritage Day” will be a welcome opportunity to educate the public on world heritage conservation.

7 . Bruno went into the kitchen and got the biggest surprise of his life. He could barely believe his eyes. “Shmuel!” he said. “What are you doing here in my kitchen?”

Shmuel looked up and his terrified face _________ a broad smile on seeing his friend. “Bruno!” he said. “They asked me to polish the glasses. They said they needed someone with tiny _________.”

He held his hand out and Bruno noticed that it was like the hand of the pretend skeleton. In reply, Bruno held his own hand out, which appeared _________ and full of life. The veins (血管) weren’t visible through the skin, the fingers weren’t little more than dying twigs (细枝). Shmuel’s hand, however, told a very _________ story.

“Shmuel! Here!” said Bruno, stepping forward and putting some slices of chicken in his friend’s hand. “Just eat them.” The boy stared at the food in his hand for a moment and then looked up at Bruno with wide and _________ but terrified eyes. He threw a _________ in the direction of the door and then thrust all the slices into his mouth in one go.

“Thank you, Bruno.” said Shmuel, giving a faint smile.

Bruno smiled back and was about to offer him more food, but just at that moment Lieutenant Kotler reappeared. Bruno stared at him, feeling the _________ grow heavy, sensing Shmuel’s shoulders sinking down.

_________ Bruno, Lieutenant Kotler marched over to Shmuel and glared at him. Shmuel looked up at Lieutenant Kotler, who frowned, leaning forward slightly as he examined the boy’s face. “You have been eating,” said Lieutenant Kotler. “Did you _________ something from that fridge?” Shmuel looked toward Bruno, his eyes pleading for __________.

“Answer me!” shouted Lieutenant Kotler.

“No, sir. He gave it to me,” said Shmuel, tears welling up in his eyes. “He’s my friend,” he added.

“Do you know this boy, Bruno?” he asked in a loud voice.

Bruno’s mouth __________ and he tried to say the word “yes”, but then he realized that he couldn’t because he was feeling just as __________ himself.

“Tell me, Bruno!” shouted Kotler, his face growing red. “I won’t ask you a third time.”

“I’ve __________ seen him before in my life,” said Bruno immediately, “I don’t know him.”

Hearing that, Shmuel wasn’t crying any more, merely staring at the floor and looking as if he was trying to __________ his soul not to live inside his tiny body any more, but to __________ away and sail to the door and rise up into the sky, gliding through the clouds until it was far away.

9 . People are looking for ways to reduce their carbon footprint. Purchasing property that is environmentally responsible is a good investment for those who are _______ their own health and the well-being of the earth. Based on this trend, eco-communities are being designed with a green _______ in mind. Dockside Green in Victoria, British Columbia is one of them.

If everything goes according to plan, Dockside Green will be a _______ community along the harbor front of British Columbia’s capital city. The community will be home to 2,500 people and will _______ residential, office, and retail space. Builders of Dockside Green have the environment in mind with every choice they make. They ensure proper ventilation (通风), and guarantee residents 100% fresh indoor air. Building materials, such as paints and wood, are _______ and non-poisonous. Eco-conscious builders use bamboo wherever possible because it grows fast and does not require _______ to grow.

Energy efficiency is one of the _______ concerns in eco-communities, such as Dockside Green. Not only do energy-efficient appliances and light fixtures (照明设备) reduce the environmental _______ of heating and hot water, but they also save residents and business owners money. Dockside Green claims that homeowners will use 55% less energy than average residents in Canada. Residents will have individual water metres (水表) _______ studies show that people use around 20% less energy when they are billed for exactly what they use. ________, water is treated at Dockside Green and reused for flushing toilets.

Planners of eco-communities such as Dockside Green must take the ________ into consideration. Dockside Green plans on reusing 90% of its construction waste. They also plan to continue using local suppliers for all of their transport and maintenance needs. This is a great way to reduce ________.

Dockside residents will be encouraged to take advantage of a mini transport system and buy into the community’s car share program. Finally, plans are underway for a high-tech heating system that will use ________ energy instead of fossil fuels.

Dockside residents will ________ excellent local services with high-quality healthcare, shopping and education at the heart of the community, along with excellent leisure facilities and plentiful green open spaces. Eco-communities will prefer the use of locally-sourced goods and services; they will be ________ places to live, promoting a sense of civic pride, responsibility and, as the name suggests, community.

10 . Rising sea levels and the potential impacts to huge coastal populations worldwide rank near the top of concerns when it comes to consequences of a worsening climate emergency. But a lesser-known danger poses an equal or arguably more urgent threat to millions around the world living at much higher altitudes: flooding from glacial lakes.

With average temperatures rising around the world in recent decades, a number of these lakes high above population centers in South America and Asia have become swollen and unstable as the reserves of snow and ice that feed them melt ever quicker.

For the first time, an international team of researchers has quantified this threat. It reports that 15 million people are in the path of potential floods from these swollen bodies of water. “Understanding which areas face the greatest danger from glacial flooding will allow for more targeted and effective risk management actions, which in turn will help minimize loss of life and damage to infrastructure downstream,” said co-author Rachel Carr, head of physical geography at Newcastle University.

In 1941, a glacial (冰川) lake outburst flood, or GLOF, from Lake Palcacocha killed thousands in the town of Huaraz below and largely inspired the beginning of research into the phenomenon. Dams and other infrastructure were put in place to relieve the threat from the lake in the 1970s, but its volume is now over 30 times greater, requiring new improvements to safely drain and release water pressure.

Lead researcher Caroline Taylor says the researchers also found that understanding the danger requires more than just counting lakes and measuring their volume. “Instead, it is the number of people, their distance to a glacial lake and importantly, their ability to cope with a flood that determines the potential danger from a GLOF event.”

In recent years, a warning system was set up at Lake Palcacocha that could give residents of Huaraz enough time to get out of the way of an incoming flood. Meanwhile, other threatened villages with no such alert system continue to rely on hope and luck.
