5. Energy is one of the biggest problems that people are faced with today. Could you further explain this problem and put forward some possible solutions?

将能源问题称为我们现在面临的最大问题一点都不过分。从历史上来看，每次能源危机特别是石油危机的产生大都容易引发战争。节约现有能源，大力发展可再生能源，都是解决问题的途径之一，希望考生能通过分析得出自己对该问题的看法。

Candidate 1: There is probably one thing that we all agree on: the world's energy reserves are not unlimited. One day, we should have no coal to keep warm in cold winter, even no gas to cook, let alone drive cars. So it is fairly clear that we need to do something about this problem as soon as possible. How can we deal with it? I think maybe we can make use of different kinds of energy, such as the nuclear energy, the solar energy, the wind energy, the tidal energy, the geothermal
energy and so on, according to the local conditions. For instance, if we live by the sea we can use the tides to produce electricity, while if in plateau section where the wind is always strong we can turn to the gust(一阵狂风) for help.

Candidate 2: Energy is someting that could dominate(支配) the fate of human beings. Primitive men(原始人) learned to use the energy of nature by drilling wood for fire(钻木取火). And then, we stepped into the era that relies on the power of steam and electricity. Nowadays, we can't even live a second without energy. Unfortunately, most of the energy we use frequently is limited and non-renewable, such as oil and natural gas. In other words, energy will run out(用完，耗尽) some day. The key to solve energy problem is to discover and develop new energy or energy substitutes(代用品). As for as we know, some kind of new energy like solar energy and unclear energy is available and may become the main resource for the next generation. Yet there're still lots of things to do before we can use them conveniently. It requires us to exploit and use the chemical energy properly. Avoiding any forms of waste is necessary. Recycling water and buying low-emission cars are some of the good choices, which are what we common people can do about the energy crisis.

能源问题是当今的热点话题，两位答题者从不同角度阐释了各自对题目的理解。Candidate 1首先以双重否定的形式强调能源储蓄并非取之不尽用之不竭的，那么如何缓解现今的能源危机就显得迫在眉睫，紧接着答题人提出几种因地制宜利用能源的方式；Candidate 2追溯了人类历史长河中，人们凭借智慧获取能源的不同手段，并指出在解决能源危机问题方面，除了要合理利用各种替代能源外，也要注意节约和回收。在表达上两位答题者思路清晰，言简意赅，值得考生学习。
