47.Water and Life（水和生活）
随着工业化（industrialization）的推进，地球上的淡水（fresh water）越来越少。生命没水就要消亡（disappear），因此要珍惜（treasure）淡水。我们如何节约用水。
While we are enjoying the rich fruits of modern industrialization, we are losing something precious on this planet. Fresh water , among others ,is dwindling down day by day, owing to the large-scale industrialization everywhere in the world.
Just as sunshine is a necessity to life, so is fresh water.. without fresh water, our human society would come to a stop.
As fresh water is such an important resource to the human society ,we need to treasure it as we treasure our life, but how?
First ,our government should have a good plan for the use of fresh water and develop industries that consume less water. Second ,waste water must be recycled. Finally everyone of us should do his bit to save water.
77．关于“电视广告的利弊”的讨论。
Recently our class held a discussion about the advantages and disadvantages of TV advertisement. Daily life needs advertisements because they can often information on goods, services, culture, employment and so on. With TV advertisements, customers can save a lot of time in shopping. TV advertisements also help factories or service providers find their market. In a word,TV advertisements have many advantages. However, we also find TV advertisements a waste of time when we don’t need them, for example, when watching TV programs. To make things worse, some TV advertisements are misleading and cheating. Furthermore, huge TV advertising expenses are shared by customers, which seems to be unfair.
Water pollution(水污染)
With the development of industry, water pollution is becoming more serious now. The polluted water not only kills fish, it is also harmful to our health. Many people get sick because they drink the polluted water. In some rivers the water is so dirty that they can even kill plants.We should fight against the pollution. We should stop using harmful things. I wish it is not a dream that in the near future we can have clean rivers again.
