1 . What is the greatest threat to mankind? Maybe different people come up with different answers. However, there is no denying the fact that the only threat to humankind, apart from humankind itself, is, without any doubt, the nature. Natural disasters are the result of natural environmental processes that have a damaging effect on people. Natural disasters can come in many forms: such as geological events like earthquakes, tsunamis or mud-rock flows, climatic events like storms, hurricanes or tornadoes and fire events like forest fires and wildfires.
The damage done by natural disasters is mainly as a result of our inability to predict exactly when they will happen. Although great progress has been made in designing and developing forecasting models for some natural disaster, complete certainty is still impossible. Even to be pessimistic there is a possibility that human beings will never achieve accurate prediction of the happening of all natural disasters.
What's more, even though we were able to predict these disasters from nature, preventing them is equally impossible. So we only have two ways to both prevent injuries or deaths and reduce economic losses to the least. These two methods are to prepare before a natural disaster comes to hit, and to manage the necessary resources and public services after a natural disaster strikes.
These two things have always been at the leading position of the projects of both national governments and international organizations. In the United States, the Federal Emergency Management Agency (FEMA) is responsible for the "preparedness, response and recovery planning" of both man-made and natural disasters.
Most natural disasters cannot be prevented, and both emergency preparation and good disaster management are the best ways to deal with them. Although natural events may appear to serve no purpose but simply to punish and destroy, natural disasters, a perfect symbol of the great power of the nature, are display of our planet's evolution and its state of change.

3 . The popularity of Chinese-owned video-sharing service TikTok(抖音)continues to grow among young people in the United States. In 2019, experts say the service more than doubled its American user base to 37 million. TikTok is especially popular with teens and young adults.
The service lets users create and share their short videos that they think interesting and useful. Many of them are under 15 seconds. The TikTok app offers a wide choice of sounds, brief parts of songs and special effects tools to help create a video. Some TikTok-based memes(表情包)are very popular. Videos often include popular songs from well-known artists and TikTok has even helped launch the careers of new music stars.
TikTok is considered a competitor to the video-sharing app Snapchat, as well as Facebook's Instagram service. Snapchat and Instagram also mainly interest young users with a wide mix of photos and videos centered largely on fashion, pop culture and humor.
Last year, TikTok was the second-most downloaded app from Apple and Google stores. Only WhatsApp was downloaded more. Research company Sensor Tower guesses people have downloaded the TikTok app 1.65 billion times.
TikTok has been used by many major companies to reach young people who use little or no traditional media. One of those companies is American-based e. l. f. Cosmetics(化妆品). The makeup company's chief marketer, Kory Marchisotto, said that TikTok is "where the Gen Z party is". Gen Z is a name used to call the generation born between the late 1990s and the early 2000s.“That's where they're all hanging out," Marchisotto said.
Companies appearing on TikTok can make money through advertising. Often, the companies create user "challenges" as part of their advertisement campaigns. TikTok users created 3 million videos that received more than 4 billion view.

4 . You may think you couldn’t live through summer without air conditioning. But in ancient China, hand fans were almost the only way to drive the heat away.
Chinese people started to use hand fans over 2, 000 years ago. The fans came in different shapes and were made from all kinds of materials. Palm leaf fans were cheap and easy to make. Feather fans marked the owner’s high status. Sandalwood fans could send out a sweet smell. Later, hand fans became far more than just something that could cool you down. They developed into works of art, in which Tuanshan—round fans, and Zheshan—folded fans, were the most common. In the shape of a fullmoon, Tuanshan were usually made of silk. They had beautiful embroidery(刺绣)featuring birds and flowers on them. Women, especially those in the royal palace, liked to use them. Poets in ancient China often compared an abandoned (被抛弃的) woman to Tuanshan. A poet in the Qing Dynasty, Nalan Xingde was a typical example. He wrote, “If only life were as beautiful as when we first met, why should the autumn wind bother to pity deserted painted fans?”
Meanwhile, men, especially the literati(文人), used Zheshan. The literati liked them because Zheshan were usually made of paper and they could paint and write poems on them. It was a way for them to show off their skills in literature, painting and calligraphy(书法). Many things were painted on Zheshan, but the most popular choice was usually beautiful scenery.
Today, Chinese people still use these fans, though not many people write or paint on them any more. This summer, why not paint one of your own?

5 . A 3-year-old boy called Casey who was lost in the woods for two days is now safe at home with his family. But he told his rescuers that he was not alone in the rainy, freezing cold woods. He said he was with a friend — a bear.
The child went missing on January 22 while playing with friends at his grandfather’s house in the southern state of North Carolina. When the other children returned to the house and Casey did not, the family searched the area for almost an hour before calling the police.
Police formed a search and rescue team to look for the young boy in the nearby woods. But two days went by and still no Casey.
Then on January 24, someone called the police saying they heard a child crying in the woods. Police followed up on the information and found Casey at about 9:30 that night. They pulled him out of some briar (多刺野灌木). He was in good health.
Casey told the rescuers that he had hung out with a black bear for two days, a bear he called his “friend”.
Officer Hughes spoke with reporters from several agencies. He said Casey did not say how he was able to survive the woods for three days in the cold, rainy weather. However, he said, “Casey did say he had a friend in the woods that was a bear. And at no point do I think he was taken away illegally.”
Doctors at Carolina East Medical Center treated Casey for minor injuries. He was then released to his family on January 25.
His mother Brittany Hathaway talked with reporters from a local news agency and thanked everyone who joined in the search and rescue efforts.
“We just want to tell everybody that we’re very grateful that you took the time out to come search for Casey and prayed for him, and he’s good,” said his mother. “He is good, he is up and talking. He’s already asked to watch Netflix.”

6 . A new study, a project of the researchers from the University of Pittsburgh in Pennsylvania, finds that a fitness tracker (健康追踪器) probably does not help with weight loss.
The trackers are designed to record your physical activity. They are usually worn around the wrist (手腕), where they record a person's heart rate. The research team looked at two groups of people. The first wore a fitness tracker and took part in health consultation with experts for best weight loss plan. The researchers compared this group with people who only got health consultation.
The study found that those only speaking with the health experts lost nearly 6 kilograms, but those using a fitness tracker lost only 3.5 kilograms. John Jakicic the lead researcher, questioned the use of these trackers for weight loss.
The study involved 470 people age between 18 and 35. Some of them were overweight, while others were considered obese. Over three fourths of them were women. All were told to increase physical activity and start on a low-calorie diet. They had their weight measured once every six months. After six months, researchers divided the group into two parts: one continued with monthly consulting, while members of the other group were given a fitness tracker. Eighteen months later, both groups showed great improvements in fitness, physical activity and diet, with no big difference between groups. However, when it came to losing weight, the people who only spoke with experts lost nearly twice as much weight.
Jakicic said, “The study's findings are important because effective long-term treatments are needed to deal with America's obesity.”More information is needed, he added, to learn how to best use these trackers to help adults who want to lose weight.

7 . Belly fat（stomach fat） has long been thought to be especially bad for your heart, but now, a new study adds more evidence to the idea that it may also be bad for your brain.
The study, from the United Kingdom, found that people who were overweight and had a high waist — to — hip ratio （a measure of belly fat） had slightly lower brain volumes （容量），on average, compared with people who were just over weight or had a healthy weight. Specifically, belly fat was connected with lower volumes of gray matter, the brain tissue （组织）that contains nerve cells.
“Our research looked at a large group of people and found obesity （肥胖）,specifically around the middle， may be linked with brain shrinkage （萎缩），” lead study author Mark Hamer, a professor at Loughborough University, said in a statement.
Lower brain volume， or brain shrinkage， has been linked with a higher risk of memory recession， which leads to being forgetful.
The new findings, published on Jan. 9 in the journal Neurology ， suggested that the combination of obesity （as measured by body mass index, or BMI） and a high waist—to—hip ratio may cause brain shrinkage.
However, the study found only a connection between belly fat and lower brain volume, but couldn't prove that belly fat actually caused brain shrinkage. It could be that people with lower volumes of gray matter in certain brain areas are at a higher risk of obesity. Future studies are needed to find out the causes for the connection.
1. What can we infer about belly fat from the new study?| A．Belly fat may have a bad influence on our brain. |

8 . We will all probably know both some introverts （内向的人）and extroverts （外向的人）in life, and yet we can gain a wrong impression about both types of people. For example, some introverts can be extremely confident and they can be able people. However, some extroverts aren’t as confident as they'd like to appear to be and often try to hide their true identities behind a false appearance.
Shyness can affect both introverts and extroverts and anybody else too. It can be very debilitating （使衰弱的）and, if severe, can have a huge negative influence upon our ability to form meaningful relationships and it can also affect our careers or jobs.
A lot of people feel shy because they have low self-respect and feel unworthy when comparing themselves to others. They find it difficult to communicate with others whom they don't know. In that case, one of the best ways of overcoming the shyness is to focus the attention on the other person instead. Shy people can try changing people's focus on someone else， so that they don't need to talk about themselves too much.
If you recognize that you are shy and see that as a lion in the way of enjoying your life. you should first overcome it by accepting that it's causing a problem for you. Trying getting into conversations with strangers is helpful. Shy people are challenging themselves and over- coming their shyness. In this way, shy people can get their own self-respect. Each time they do it, this will be repeated until they feel confident enough.
Like any negative thought， determination can also help you beat shyness and having a positive attitude is the key to overcoming the shyness.

9 . This year, the hole in the ozone layer (臭氧层）over Antarctica has expanded to one of its largest sizes and deepest levels in years.
So how big is the ozone hole? On Sept 20, the hole over Antarctica peaked (达到高峰) at 24.8 million square kilometers, which is three times the size of the United States. It has increased by 8.4 million square kilometers since 2019.
That puts it in about the same ballpark (范围) as ozone holes in 2015 and 2018, which respectively recorded peaks of 25.6 and 22.9 million square kilometers.
"The 2020 ozone loss shows that we have to remain vigilant (警觉的) and maintain continuous observations (观察)," said World Meteorological organization Secretary-General Petteri Taalas.
The ozone layer is important because it acts like a sunscreen, blocking harmful ultraviolet light (紫外线) from reaching our planet's surface. Without it, humans and animals will be more likely to experience skin cancers, immune suppression (抑制), cataracts (白内障) and premature (提前的) aging.
Of course, humans play a large role in the depletion (消耗) of the ozone layer. The loss of ozone in the Antarctic, as well as the Arctic, is due to the large amounts of ozone-destroying gases caused by human activity. Once released into the atmosphere, these gases can remain for decades. In extremely cold weather conditions, they trigger (激发) chemical reactions that destroy the ozone layer.
"The Arctic stratosphere (平流居) continues to be vulnerable (脆弱的) to ozone-depleting substances linked to human activities," said Taalas.
Marcus Rex, a scientist at the Alfred Wegener Institute in Germany, told Nature that the ozone hole doesn't threaten human health but that over next month, there is a possibility that it might move to more populated areas. In that case, he recommends more sunscreen.
Although it seems bad, scientists are hopeful that Earth can heal (治愈) itself. Researchers believe the ozone hole will eventually heal and around 2050, Earth's ozone layer will return to normal.

10 . In work, as well as in life, doing what needs to be done in order to reach our goals can be difficult. Without a good system in place, it is easy to lose focus, waste time and lose track of our most important tasks. Luckily, one of the most efficient(高效的)useful ways is also one of the world's easiest---the Pomodoro Technique.
The Pomodoro Technique was developed by Francesco Cirillo in the late 1980s, which breaks down your work into 25-minute blocks(一段时间)divided by short breaks. Cirillo named the system after the tomato-shaped kitchen timer(计时器)that he used to track his work time when he was studying in university, where he developed a habit of doing short blocks of work followed by resting periods. He realized this method could help him work with time instead of struggling against it. In 2006, Cirillo published his Pomodoro Technique manual for people to download free of charge. It was downloaded over two million times.
The Pomodoro Technique was built around a handful of important steps. First, choose a task that you'd like to get done. It can be something big, something small, or something that you've been putting off for months. What matters is that you are ready to give it your full attention.
Next, set a timer for 25 minutes. Try to spend the full 25 minutes with your complete attention on the task. Then, when the timer goes off, take a five-minute break. Sit back, have a drink, go for a short walk, or do something else that doesn't relate to work. Treat yourself to a longer break that lasts 15 to 30 minutes after you have completed four of these 30-minute cycles. In theory, the longer break will allow your brain to relax, reset, ready for the next round of Pomodoros.
After trying the Pomodoro Technique, you may want to experiment a little. Some people have found that 90-minute blocks work best, while others might perform better with more flexible periods. It varies from person to person. Just remember, like many things in life, simpler is often better!
