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."

Recently, a tourist said in a video that there was no hot water on the Huangshan Mountain. Some tourists also complained(抱怨) online that they failed to get hot water for cooking instant noodles since it was banned(禁止) by the scenic area. For a time, "Why doesn't the Huangshan Scenic Area provide hot water for instant noodles?" became a hot topic on the Internet. Many people thought this rule was unreasonable.

Later, the staff of the Huangshan Scenic Area(景区) replied to the question: In order to protect the animals, plants and environment of the Huangshan Mountain, tourists are advised not to eat instant noodles in the area.

Before the rule was made, leftovers(残羹) and packaging materials from instant noodles were often found throwing in the scenic area. These seriously harm the soil and plants. In addition, animals, such as squirrels and birds, may eat these leftovers by mistake, which poses a threat(威胁) to their health.

In fact, eating instant noodles is not banned on the mountain but it is not encouraged, according to a leader of the scenic area. Actually, the ban on sales of instant noodles on the mountain was put in place in 2006.

The staff at the scenic area said, "Tourists can get hot water at the rest area in the scenic area. They are also allowed to bring their own food products such as bread and self-heating meals. For those who do not bring food, the scenic area has supermarkets and restaurants."

This action quickly received understanding and support from the public. "This is necessary. We should follow the rule while enjoying the beauty of nature," one tourist shared his opinion online. "I support the rule, and we should all play a part in protecting the environment."

When the first person looked up at the sky, the imagination of the space began. In China, there are many stories about the exploration of space. 

Thousands of years ago, there was a lady named Chang'e who flew to the Moon and lived there. It's a story just living in myths(神话). In the Ming Dynasty, a man named Wan Hu used the machine which was made of a chair, some fireworks and a kite as a rocket. He wanted to go into the space but failed. He was considered as the first human to try to explore the space. 

In 2003, when Shenzhou V successfully set off, Yang Liwei's words" ask for instructions to go to the war" brought tears(眼泪) to our eyes. Carrying the flying dream of the Chinese nation for thousands of years, the first" space visitor" of China, excellently completed his task. It started the space age for the Chinese. In 2008, Zhai Zhigang, Liu Boming and Jing Haipeng returned to space by Shenzhou VII. Zhai achieved the success of the first Chinese spacewalk. "I am out of the capsule(太空舱), I feel good, " he told the world proudly. 

In the following years, China kept on making its way to explore more about the space. Especially in the recent two years, China has launched (发射) Shenzhou XIII and Shenzhou XIV. Six astronauts have been sent into the space. 

From 2003 to 2022, China's manned space- flight has gone through about twenty years of hard, but successful journey. With the take- off again and again, Chinese people go farther and farther in space, but our dream is getting closer and closer. 

In the near future, Chinese people will be sent to the Moon and land on it.
