Tu Youyou, a Chinese scientist, became the first female scientist from China     1     (receive) a Nobel Prize for her contribution in fighting against malaria — one of the     2     (deadly) diseases in human history. Her discovery of qinghaosu helped increase the     3     (survive) rate of malaria patients worldwide. Born in 1930 in Ningbo, Zhejiang Province, Tu studied medicine at a university in Beijing from 1951 to 1955. She completed further training     4     (course) in traditional Chinese medicine before joining the Academy of Traditional Chinese Medicine. In the 1960s, she became head of a team     5     was searching for a cure for malaria. After collecting over 2,000 traditional Chinese medical recipes and     6     (make) hundreds of extracts from different herbs, Tu eventually discovered qinghaosu extract that could treat malaria in mice.     7     facing several challenges, including lack of research equipment and     8     (safe) data, Tu and her team never gave up and finally discovered qinghaosu in November 1972. Since then, it     9     (benefit) about 200 million malaria patients worldwide. In her Nobel Lecture, Tu encouraged scientists to explore more traditional Chinese medicine and raise     10     to a higher level.

We’ve all heard the advice to “get out of your comfort zone” by taking on a new challenge. A recent study goes a step     1     (far): Make discomfort a direct goal. That’s more likely to motivate you than if you focus on     2     you hope to learn.

In the first of five experiments, the researchers assigned several hundred students training at Second City Chicago     3    (participate) in a small-group improvisation(即兴) exercise, and then instructed half of the group that their goal during the session was “to feel     4     (embarrass) and uncomfortable.” The rest, those in the control group,     5     (tell) to “feel yourself developing new skills.” Members of the first group kept at the exercise longer than the others did and took greater risks. Experiments involving other dimensions of higher personal     6     (competent), such as learning about gun violence and hearing about opposing political beliefs,     7     (produce) similar results.

Seeing anxiety as excitement has proved a way to improve singing in front of strangers, and     8     (think) of stress as a means to boost achievement has also been confirmed. “When people reinterpret negative experiences as functional, they are more willing to engage     9     tasks that call forth those experiences,” the researchers explain. “Instead of seeing discomfort as unrelated to the goal     10     a signal to stop, they will start perceiving it as a sign of progress toward their goal.”

It would not be surprising if we found it difficult to distinguish between reality and science fiction in the future. For example, robots first appeared in sci-fi novels, but now robot soldiers have already been tested out in war. Robot     1     (expert) have also built robots that can see, talk, and do other things like humans. Although a robot     2     looks more like a human than     3     machine could make many people a bit uncomfortable, we have to admit that it is a     4     (fascinate) possibility. Sophia, currently said to be the most advanced AI robot in the world, is a great example. She     5     (interview) many times, appeared on the covers of magazines, and become the first non-human in the world to be given citizenship by a country. When it comes     6     games, 2017 became a year in which AI defeated humans in so many games that AI researchers say that it will not be long     7     AI can win at almost everything. So have we lost the dignity of being the most intelligent creature? Maybe in the future, as AI becomes even more     8     (intelligence), it will become a major threat to humans.     9    , some people dismiss this fear. They believe if AI can handle tasks like     10     (calculate) and driving for us, we will have more time for creating, thinking, and “being human”.

Most of the Chinatown in San Francisco     1     (destroy) in the 1906 earthquake, but the city and residents rebuilt it, taking care to include lots of Chinese architecture.     2     (traditional), visitors enter Chinatown through the legendary Dragon Gate, which was built using materials     3     (donate) from China. Other famous sites include the Tin How Temple and Ban k of Canton, to name but a few. Visitors can also spend hours just exploring the interesting sights, smells, and sounds of China. Portsmouth Square is also a key site, being the centre of Chinatown. It has a long and famous history,     4     the author Robert Louis Stevenson having spent much time writing there. These days, the square is a great place to see traditional Chinese culture in real life, such as games of Chinese chess, and people     5     (practise) tai chi.

The stores in the Chinatown offer     6     unique range of souvenirs, goods, and clothing. All kinds of traditional Chinese herbal medicine can be found, too,     7     there are Chinese tea stores, where visitors can taste and buy varieties of Chinese tea.

But perhaps     8     many tourists and San Franciscans treasure most about Chinatown is its food. There is Chinese food     9     (suit) everyone’s taste, with traditional dishes from all over China.

Chinatowns are an important part of the     10     (diversity) culture of the USA. They allow visitors who have never been to China to experience traditional Chinese culture first hand.

Fusong County in northeast China’s Jilin Province was abuzz (热闹) with activities last winter, especially when the World Robot Contest Finals 2023     1     (hold) there. The finals attracted over 5, 000 youngsters from across the country     2     competed fiercely with their self-designed robots.

“We need to compete in assembling, programming and operation. I believe that maintaining a resilient mindset     3     (be) the key to winning out,” said Yu Yiyang , who is     4     fifth grader from Shanghai and has a profound passion for robots. Yu said that from robotics class, he acquired knowledge beyond conventional textbooks, refining his practical skills and     5     (encourage) innovative thinking.

Many of the contestants     6     (receive) robotics education before participating in the robot contests. Their skills, mental strength and the sense of team work improved a lot as a result of their     7     (expose) to such competitions.

The young contestants,     8     various places and with diverse backgrounds, offered a glimpse of the popularity of robotics education among Chinese students. For many, learning robot programming and participating in robot contests not only offer     9     (opportunity) to sharpen their cognitive abilities and their skills, but also serve as an effective means to boost     10     (they) spirit of teamwork.
