Better hygiene (卫生) habits can help you stay healthy

According to the World Health Organization, 60 percent of people's health problems are related(与…相关) to everyday hygiene habits. As the COVID-19 spreads across the world, governments and organizations in many countries have suggested that people should pay more attention to their daily hygiene practices.

In China, for example, people usually share dishes together at the dining table. But this habit has a high risk of spreading diseases through saliva(唾液). To fight against COVID-19, many cities in China, including Beijing, Shanghai and Guangzhou, have called on people to order separate(分开的)meals or use serving chopsticks(公筷) to take their food. Many people also suggest that Chinese should continue these habits after the outbreak.

In the US, the Centers for Disease Control and Prevention has asked people to develop healthy hygiene habits. For example, people should cover their mouth and nose with a tissue when they cough or sneeze.

    According to a survey by YouGov, a British market research company, many Americans have taken action to change their daily habits in the face of COVID-19.

What would life be like if you were a rocker, a soccer player, a professor(教授）at Stanford University, and a Nobel Prize winner? Carolyn Bertozzi from the US lives such a cool life!

Bertozzi, 56, wins this year's Nobel Prize in chemistry and becomes this year's only female(女性) winner in science and the eighth female to receive the chemistry prize in history.

Bertozzi won the prize for studying the sugar coats of cells(细胞）. She has found a smart way to connect cells together. This finding helps to develop better tests for serious diseases like cancer.

However, Bertozzi said she only fell in love with chemistry until her second year at Harvard University."Most of my classmates thought the class was very difficult. But I liked it a lot because in my eyes the problems were challenging even though it usually took me long hours to solve them."

Besides doing science studies, Bertozzi has lived a colorful life. She was a keyboarder in a rock band and she also played soccer, winning an athletic scholarship from Harvard.

Moreover, Bertozzi never forgets her job as a female scientist. "In the late 1980s, only 10 percent of the students were females," she told Chemical & Engineering News. "There were maybe only one or two females in a lab, so we tried to support each other by starting a monthly get-together. Now, I'm so glad to see more and more females taking part in science." In 2022, Bertozzi won an award from the American Association for the Advancement of Science for her work to increase diversity(性别多元）in science.

Welcome to the Olympic Museum! Our museum is located in Lausanne, Switzerland, is the home to the world's largest and most comprehensive Olympic collection. This year, as the Olympic takes center stage, there is no better time to visit us. We offer a group tour project for students. Here's what you can expect from your visit:

1. Educational exploration: Learn about the history of the Olympic Games through objects, photos and videos. 

2. Special focus on Paris Olympics: Find out more about the 1900, 1924 and 2024 Summer Olympic Games in Paris. 

3. Interactive discussions: Take part in fun discussions with other students. These will be led by a museum educator. You will talk about the true meaning of the Olympic torch(火炬), the Paris 2024 mascots(吉祥物) and more. 

①Are you a shy person? Do you expect to become outgoing? Being outgoing can help a lot in your life. In fact, being outgoing is not as hard as you think. Here is some advice on how to become outgoing. 

②You can start to try becoming outgoing when you stay with your friends. But the real challenge(挑战) comes when you meet strangers or new friends. Smile at them, and usually they will smile at you, too. You may find it easy to start talking in this way. 

③Start a talk positively (积极地). Try to speak first. Simple greetings such as"Hello!""How is it going?" and"It's a little cloudy today, isn't it?" are a good start. After that, you can talk more. For example, you can talk about the latest news. But you'd better read some news in newspapers and have your own ideas first. Or you may find that you won't have much to say. 

④The best way to become outgoing is to go out. It is also a very important step. Usually those who like to do the same things can get to know each other better. 

If you like playing sports, go to a sports club. You may make many new friends there if you get over your shyness.
