第24题:[简答题]举例说明什么是热厚型物质,什么是热薄型物质,分别有什么特点?
参考答案:热厚型物质，典型如木头,火灾蔓延慢，是因为表面吸热之后，向内部传热，因此点火过程需要预热时间,表现在燃烧缓慢，甚至需要长时间的点火预热过程。热薄型物质典型如纸张，火灾蔓延快，是因为表面吸热之后，无法向其他地方传热（因为背后是空气)，能量蓄积在表面的结果,就是表面升温快点火快。火灾蔓延的过程，就是持续点火的过程。而且，由于火焰的预热作用,火灾的发展不是线性的,早期一秒两秒之差，就是后期能否控制住火势的结果问题。因此热薄型材料的多少,对于火势的控制至关重要。

[参考范文一]
What is the most urgent issue facing the world people in the BAst century
In my opinion, the most urgent problem the world people facing is education. As society develops, the development of technology, the training of professionals in various fields depend on education. Without it, there would be no civilization and modernization at all.
The BAst century is an information age. New technology determines one’s success or failure in the competitive world. If a country can’t level itself up to the leading stage of technological advance, then it will not be able to compete effectively and may fall further behind its foreign competitors. This is a world trend; no one including individual can ignore.
Computer is the brightest star in technology. It allows vastly increasing production for those who arc able to master it. But it also threatens those who fail to adopt it with permanent second-class citizenship in the world economy. So in broad sense, we may say, to master computer means the mastery of the world. And computer is a combination of arts and technology. Only through education, can we train various talented persons required. They in turn develop newfangled computers and spur our society forward.
In order to catch up with the world level, a country must quicken the steps of educational reform, especially in universities—the cradle of knowledge, the base of science, the training center of qualified persons. A large sum of funds should be invested to modernized laboratories and libraries, to introduce talented professionals, thus laying the foundation for offering advanced courses. With strong basis of education, we can stand up to whatever difficulties.

The Most Urgent Issue Facing The World People In The BAst Century
More than one billion people in the world lack access to clean water, and things arc getting worse. Over the next two decades, the average supply of water per person will ’drop by a third, possibly condemning millions of people to an avoidable premature death. Therefore, in my opinion, the most urgent issue facing the world people in the BAst century is water crisis.
Foremost, our need for water is constantly increasing due to the growth of population. As a result, water crisis threatens the world’s development and security. As the world’s population continues to expand, and climate change alters the hydrology of river basins, heightened hunger and disease will follow. Secondly, with the development of industry and agriculture, more and more water is polluted, which lead to the reduction in drinking water. Moreover, in our daily life, people waste a large quantity of water without any awareness. The deteriorating conditions of water resources may bring nations into conflicts that-although they may not lead to war-will test diplomats’ skills to the limit.
It’s not too late to mend the problem, however. To start with, the answer lies in the development and large-scale application of relatively simple technologies. Sophisticated solutions such as solar-powered desalination plants have a role to play, particularly in wealthy yet arid countries. In addition, water is a shared resource that requires global cooperation to manage appropriately. We should take every measure to prevent the extant water resources from being polluted and to make good use of water as possible as we can. How we respond to today’s water crisis will determine whether we actually know how to survive and whether we can survive and develop in a sustainable way.
