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.

    A grand military parade was held in the morning, showing the great progress made by the Chinese armed forces in recent years. About 15,000 officers and soldiers took part in the 80-minute parade in front of Tian'anmen Square. Then, a mass pageant(群众游行展) showing China's historical achievements and the nation's great rejuvenation(伟大复兴)was held. It was seen as a lesson on Chinese history and how far the nation has progressed. The mass pageant lasted 65 minutes and was divided into five parts, each part showed respect to Chinese leaders in the past and leaders now, from Mao Zedong to Xi Jinping. In the evening, a gala(盛会)took place in Tian'anmen Square. The songs, dances and fireworks celebrated the nation and its people.

    President Xi expressed warm National Day congratulations to Chinese people home and abroad. Standing on the Tian'anmen Rostrum in Beijing, where Chairman Mao Zedong announced the founding of the PRC on Oct 1, 1949, Xi recalled Chinese history. He also showed a road map for the country to realize the Chinese dream of national rejuvenation. He called for efforts to make a better life and to keep making achievements. The parade and celebrations have set off Chinese people's patriotism (爱国心)and a strong sense of pride.

    IQ scores have been measured (测量)since 1916, when Alfred Binet developed his intelligence list as follows:

    Some very famous people are known for their high IQ level. Jill St. John who has the highest score on this list was a major American film actress during the 1960's and 1970's. Jill was chosen to the University of California at the age of 14.

    Scientists have estimated (估算)the IQ scores that some famous historical people might have got. This was done by looking at their work and their ideas and the way they put them together Leonardo da Vinci gets that high score not only for his art but also for his idea of the helicopter (直升飞机). Without modern scientific tools, he created a lot of design drawings and patterns, which was ahead of his time.

A: Mr. Liu, can I ask you some questions about Mars?

B: Sure, go ahead.

A: Is Mars hot?

B: Mars might look red-hot. But don't let its color fool you. Mars is much farther away from the sun than Earth. So it gets less light and heat.

A: Why "Mars"?

B: Mars takes its name from the Roman god of war (罗马战神). In China, the red color makes people think of fire. So they call the planet "fire star".

A: Are there Martians on Mars?

B: Unluckily, we haven't found any "people" on Mars yet. They are kind of like Santa Clause. Nobody can see them, but many people believe they are real.

A: Will we lose weight on Mars?

B: Living on Mars could be good in many ways. For example, you might not need to go on a diet to lose weight. If you weigh 50kg on Earth, you will only weigh 19kg on Mars. This is because the surface gravity (表面重力) on Mars is only about 38 percent of that on Earth. Do you want to know your weight on Mars? Just multiply your weight by 0.38. That's it.

A: Thank you. We know a lot about Mars now.

B: You're welcome.

    As more information comes out about 10-year-old Cindy Smith's death(死亡), worries about amusement park safety(游乐场安全性) grow.

Cindy is not the first child who died on an amusement park ride. 25 years ago, the mother of a 14-year-old girl waited to pick up her daughter outside Worlds of Fun. Laura Barry never saw her daughter Rosie alive again.

"My heart goes out to the Smith family more than they can ever possibly know," said Barry. She is one of the few people who truly know the hurt that family is feeling.

In 1995, Rosie's mom said that something went wrong on the Timber Wolf the night Rosie died. Police found no evidence(证据). Two men told the police that they saw Rosie standing before she fell out of the car.

"I couldn't believe that such a thing could happen still and again," said Barry. She believes Rosie's death should have been a wakeup call for amusement park safety.

She finds that not much has changed in the past years. Amusement parks race to build bigger, taller, faster rides. In her opinion, amusement parks just try to bring in visitors and give them the idea that riding is good, safe and fun. She believes that parks should have put safety first.

There is no exact number of amusement park deaths each year. It is quite low according to some websites. But Barry doesn't accept that. "My daughter was the only person that had ever been killed at Worlds of Fun in all of the years, among all of the thousands and thousands of people that went there. The number doesn't mean anything, you know, because when your child is the one, that's one too many," she said.
