How Do Avalanches Happen
If you’re ever skiing in the mountains, you’ll want to be aware of avalanches. An avalanche is a sudden flow of snow down a slope, such as a mountain. The amount of snow in an avalanche (21) slope in dozens of feet of snow.
Avalanches (22)
be caused by natural things. For example, new snow or rain
can cause built-up snow to loosen and fall down the side of a mountain. Artificial triggers（诱发因素）can also cause avalanches. For example, snowmobiles, skiers, and explosives (23)

snowfall is greatest.
As they are dangerous to any living beings in their path, avalanches have destroyed forests, roads, railroads and even entire towns. Warning signs exist that allow experts to predict -- and often prevent -- avalanches from (25)

When deadly avalanches do occur, the moving snow can quickly reach over 80 miles per hour. Skiers caught in such avalanches can be buried under dozens of feet of snow. (27)

Program
Under the terms of the Nuclear Non-Proliferation Tready（不扩散核武器条约）, only five countries are considered to be “nuclear - weapon states.” China is one of them. This military achievement would have been 31 without the contribution of Deng Jiaxian, a leading organizer of China’s nuclear weapon programs.
Deng went to the United States in 1948 for further study, and received a doctorate in physics two years later. Just nine days after graduation, the then 26-year-old returned to the newly - founded People’s Republic of China with 32 physics knowledge. He became a research fellow under the leadership of Qian Sanqiang and started his theoretical nuclear research in cooperation with Yu Min.
From 1958 on, Deng spent over 20 years working 33 with a team of young scientists on the development of China’s first atomic and hydrogen bombs. Originally, they were prepared to receive training by experts from the
Soviet Union. Soon after, however, the Soviet government tore up its 34 with China and removed all its experts. Deng had to lead the team of 28 members with an average age of 23 on a mission to 35 the mysterious power of atomic physics.
There was ridicule（嘲笑）following the 36 of the Soviet experts that China wouldn’t be able to build
an atomic bomb within 20 years. Deng said to his colleagues, “It is in the interest of the Chinese people to develop nuclear weapons. We must be willing to be unknown heroes for our lifetime. It is worth the risk of suffering, and it is worth our 37 to this cause.”
As the leader of China’s atomic bomb design, Deng gave lessons himself and organized a team to translate and study the 38 foreign language materials. In the meantime, he never stopped thinking about the direction of atomic bomb development.
Following the successful test of the first atomic bomb in 1964, Deng joined the research group led by Yu Min. They immediately started the design of the hydrogen bomb, which was 39 in 1967. From the first atomic bomb to the first hydrogen bomb, China spent only two years and eight months on development.
Deng passed away in 1986 because of cancer. In the last month of his life, the 28-year secret experience of this great scientist was 40 , and his reputation began to spread throughout China. In 1999, along with 22 other scientists, he was awarded the special prize of “Two Bombs, One Satellite Meritorious Medal” for his contribution to Chinese military science.
