For decades, China had wanted a Nobel Prize in science. Tu Youyou, a researcher who helped to develop a malaria (疟疾) medicine, finally won the country that honor.

In fact, Tu is not the only scientist in China who is catching the world's attention. In 2016, the Nature journal published a list of the top 10 science stars in China. Gao Caixia and Cui Weicheng are two of them.

Gao Caixia has been devoted to genetic engineering for her whole career. She is known for using CRISPR-Cas9, the revolutionary gene-editing technique that is sweeping through biology labs around the world – in crops.

At first, Gao was unwilling to take up gene editing using CRISPR-Cas9 because her lab at the Chinese Academy of Sciences' Institute of Genetics and Developmental Biology in Beijing had already created mutations (变异) in 82 genes using an older type of technology. But after thinking carefully about it, she decided to give it a try.

After a year of hard work, her lab finally succeeded. Gao worked on genetic engineering in wheat, a crop that is famous for being difficult to work with. Now she is considered one of the best in the world at engineering wheat.

Cui Weicheng is the developer of China's record-setting Jiaolong submersibl (e  潜水器) . He is now a professor at Westlake University. In 2012, Cui rode inside China's Jiaolong submersible and reached a depth of more than 7,000 meters in the Pacific.

Thanks to Jiaolong and the 57-year-old developer, China is now one of only a few nations that can explore the deep sea. Jiaolong can travel deeper than any other manned research submersible currently in use, which shows China's increasing ambition and leadership in deep-sea research.

Halloween is a great time in the lives of both children and adults. However, even the best Halloween can be ruined by trees filled with toilet paper and egg residues(残渣)that won't wash of. How can you keep your home safe on Halloween? There are some measures you can take.

Make it known that you're at home. Pranksters are less likely to play a trick if they know someone is at home. You may want to close the glass on your screen door and open your front door so that you can see everyone moving around outside. This also allows pranksters to see that you're at home.

Turn on the lights inside your home and outside. Having all the lights on lets pranksters know that you're not only at home, but you're awake. If a prankster knows you're awake, he'll be more likely to skip (快速溜走)your house and head for another one. Even if you need to get in bed early, keep all the lights on except in your bedroom. Pranksters aren't going to know which room is your bedroom.

Ask the police to patrol the area. It's a policeman's job to keep citizens safe, especially on Halloween. In some cities the crime rate can increase fast on October 31. A polite call to your local police station should get you the service you need. Above all, no pranksters are going to throw eggs at your house when the policemen are patrolling the area.

Set up a neighborhood watch. One of the best ways to keep your home safe on Halloween is to get the neighbors involved. No one wants his trees covered with toilet paper. Ask your neighbors to keep their eyes open and to follow the same steps you've taken to help keep your home safe. If the entire neighborhood is lit up, pranksters are less likely to stop by.

Theater is one of the oldest and most important art forms in world culture, it is also one of the richest art forms. Many people work together to bring a play to life. There are playwrights, directors, set designers, costumers, lighting technicians, and, of course, actors. If the performance is a musical, the skills of a songwriter, a choreographer, and musicians are also required. The excitement of opening night can be felt by the people waiting to watch a performance and by the performers and workers backstage waiting for the curtain to go up. Live theater is thrilling because no one really knows how well the play will go until it is performed.

The word theater comes from the Greek theatron, which means "a place for seeing." One concept from Greek theater that is still seen in some plays today is the "Greek Chorus". This consists of several actors or characters watching the action of the play(almost like the audience) and then commenting on what whey just saw with either reactions or dialogue.

Although most people think of the theater in terms of a play performed on the stage, theater has taken on a much broader meaning in the modern world. You may find yourself walking into a theater with no seats in the rows. Instead, you are seated among the set pieces, which makes you part of the setting. Sometimes theater may come to life on a street corner, or in a classroom. The excitement of theater is in its very nature—-it is an art form that changes as it is interpreted(诠释) in different ways by different people. That is probably why the works of the greatest playwright of all time, William Shakespeare, are still performed and enjoyed today, both in classic and new interpretations.

What will restaurants look like in the future? What would your dinner taste like if a robot cooked it? A robot restaurant in Tianjin may give you the answers. Covering an area of over 400 square meters with a total of 112 seats, the X Future Restaurant is a robot restaurant opened in November 2018. The restaurant has amazed customers with its fully automated(全自动的) technology, which covers every step of the dining experience, from ordering to cooking to serving the dishes and even taking payment.

Entering the restaurant, one can order dishes by simply scanning(扫描)the QR codes on the table. There are over 40 choices of dishes. After taking the order, "robot cooks" prepare dishes using fixed time, temperature and ingredients designed by famous Chinese cooks.

"As the cooking is controlled by a computer system, the taste and quality of dishes can be good," said Li Xiaokui, manager of the X Future Restaurant.

Robots also complete the delivery of dishes. Without following any designed route, the robot waiters serve meals thanks to automated driving technology, which helps each robot timely change its route when something is in the way.

These eye-catching technologies have received wide praise from customers. "The dishes taste surprisingly good. I couldn't believe that they were made by robots, especially dishes that were difficult to cook." one customer said. "The application of robots has increased our efficiency(效率)and cut down our costs," Li said, "I think robot restaurants will develop fast and have a bright future."
