Many people may not know the name of the girl in the photo but her large and clear eyes can often be seen in newspapers.

    Her name is Su Mingjuan and now she's more than 30 years old. In 1991, when Su was only 8 years old, Xie Hailong, a photographer from China Youth Daily, took a picture of her in a classroom which was in a poor condition in Anhui.

    The photo was later used as a poster for Project Hope. It has become a symbol of the country's efforts to make more people realize the importance of education. Her large and clear eyes crying for knowledge in the picture have moved a big number of people across China, who have donated (捐赠） money to help children continue their schooling since then.

    Having received help from Project Hope, Su herself has also been helping poor students. She began to study at Anhui University in 2003. After entering college, she wrote to the China Youth Development Foundation, the organizer of Project Hope, to transfer her living allowance (补助) of 900 yuan a term to other students in need. And she began to do part-time jobs to make money. After graduation, Su found a job in a bank. Since she started working, she has donated 1,000 yuan every year.

    Since it was started in 1989, Project Hope has received about 13 billion yuan in donations from home and abroad. And the money has been used to build over 19,000 primary schools and help over 5. 5 million children.

It's possible to get ill at any time of the year, however, it seems that more people get sick in winter. So why does this happen?

The biggest reason is that the cold weather brings us indoors. Spending more time indoors can make us get close with others but it will be easier for us to catch a cold or flu(流感). Moreover, according to scientists, the virus(病毒) is protected(保护) by its own fatty coating(脂质外层), but this coating changes into liquid(液体) at higher temperatures(温度). So the virus is less able to travel in summer. In colder weather, the coating keeps complete(完整). That's why the virus will get into our body easily.

What's more, the air is drier in winter both indoors and outside. The dry air is good for the travel of viruses. Therefore, viruses can travel farther and stay in the air for longer. Besides, in winter, we often close our windows and doors to keep warm. Less fresh air indoors helps viruses live longer in a room.

What about other reasons? Cold weather may be bad to our body and immune systems(免疫系统). A study found that to lower the temperature inside the nose by 5℃ kills nearly 50% of its virus-fighting cells(抗病毒细胞).

In order to stop illnesses, here are some tips for you. We should do more outdoor exercise to keep our body strong. It's a good way to take a walk with your close friends and enjoy the fresher air in the park on weekends. Besides, washing our hands can often lower the travel of viruses.

 On Oct 11, robot history was made when Ai- Da, a human- like robot artist talked at a meeting in the UK. The topic for the meeting was"A Creative Future".

 Ai- Da paints using cameras in her eyes and robotic arms. She" thinks" and answers questions using AI algorithms (算法). She has painted the UK queen and had her work presented in galleries(画廊).

 Describing herself, Ai- Da told people at the meeting that"I am a robot and I depend on computer programs and algorithms" and" although not alive,I can still create art". Amusingly, at the meeting, Ai- Da" slept"— it shut down and had to be restarted. But her ability to answer questions in real time shows the huge developments of AI. These are developments that will continue.

 One person who seems interested in this is Elon Musk. He is planning on creating his own AI robots for his company, Tesla. Musk presented Tesla's human- like robot, named Optimus, at Tesla's AI Day on Sept 30. Tesla showed videos of their robot doing simple tasks like carrying boxes and watering plants, said CNN.

 With robots becoming more and more part of our daily lives, we may have to learn to live with them. But will people be happy to have these robotic friends or will they feel threatened(威胁的) by them? As Ai- Da said," Technology can be both a threat and an opportunity."

Do you know the lion dance? It's part of traditional Chinese culture. People often perform in the night 1 the Chinese New Year. They also perform it for other happy occasions（时刻）. The lion dance is believed to 2 good luck and success. 

There are many different stories about how the lion dance 3 . One of them is like this! Hundreds of years ago, a monster called Nian came to a village in China. The villagers were 4 . Luckily, a lion chased（追逐）Nian away. A year later, Nian came back again, 5 this time the lion couldn't help. The villagers had to 6 themselves. Their "lion" danced, jumped and chased Nian away. For this 7 , people began to perform the lion dance before the Spring Festival to chase bad luck away. 

There are two different kinds of lion dances. In the southern lion dance, the dancers try. 8 to perform like a real lion. Their "lion" may shake its body. The dance can be funny. The other kind is the 9 lion dance. It has more martial（军事的）art skills like rolling and jumping. Both the southern and northern kinds are very interesting to watch, but it takes a lot of 10 to perform well. Both kinds are considered to be traditional performing arts of China.
