    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.

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.

    When people think of tigers, words like" strong" and " dangerous" come into their mind. But now, the big animal is calling for our help. There were once eight kinds of tigers in the world, but three died out during last century. In the past 70 years, the number of Siberian tigers has gone from as many as 300 to somewhere between 18 and 22.

   World Wildlife Fund started a programme. It is about to put an end to tiger poaching(非法狩猎) and save wild tigers. China, together with 12 other countries, has joined in. The aim is to double the number of wild tigers in the next ten years.

According to the research by Chinese officers and WWF, the Siberian tiger is already one of the planet's most endangered animals. "If the government doesn't do anything, it's quite possible that there will be no more Siberian tigers in China in 10 to 20 years." said Zhu Chunquan, director at WWF Beijing office.

    Wild animals such as deer and wild bears are tigers' main food. The poaching of these animals is the greatest danger to tigers. Another one is the trap(陷阱). "Volunteers from WWF remove traps every year, but we cannot clear all the traps ourselves," Zhu said. The most important thing people can do is to save the animals tigers eat." To protect the tigers, we need to call on more people to stop hunting wild animals."

    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.
