II. Translation

The offensive had already lasted three days, but we had not gained much ground. Our troops engaging the enemy at the front were faced with strong/fierce/stiff resistance. The divi-sion commander instructed our battalion to get around to the rear of the enemy and launch a surprise attack. To do so, however, we had to cross a marshland and many of us were afraid we might get bogged down in the mud. Our battalion commander decided to take a gamble. We started under cover of darkness and pressed on in spite of great difficulties. By a stroke of luck, the temperature at night suddenly dropped to minus 20 degrees Celsius and the marsh froze over. Thanks to the cold weather, we arrived at our destination before dawn and began attacking the enemy from the rear. This turned the tide of the battle. The enemy, caught off guard, soon surrendered.

Can Man Triumph over Nature?

When people talk of man triumphing over nature, many things come to mind. One thinks of successes in medicine in the fight against disease, such as the invention of antibiotics and the promise held out by advances in biogenetic engineering. On a broader scale, one thinks of man's success in harnessing new forms of energy from steam power through oil to nuclear power.

Yet, nature has often hit back in unexpected ways to these attempts to tame it. New forms of

Appendix I - 98 -

disease that are resistant to antibiotics are constantly developing. Burning fossil fuels has led to fears of global warming; while nuclear power has produced dangerous waste that will remain a hazard for generations to come.

However, perhaps to talk of man triumphing over nature is the wrong way to look at the matter. We need to find ways to work with nature rather than forever fighting against it.

Part I Pre-Reading Task

Script for the recording:

What will the world be like in five hundred years' time? A thousand years' time? Or more? Some people are optimistic, looking forward to a better world. Others are pessimistic, and fear that things can only get worse. The writer of the song you are about to listen to takes the pessimistic view. Looking further and further into the future things seem to him to get worse and worse. By 3535, he foresees all our thoughts and feelings will be shaped by drugs. Looking further still into the future he foretells that our bodies will waste away as machines do everything for us. Family life as we know it will fade away as children are bred artificially, chosen, in the words of the song, \the bottom of a long black tube.\planet and avoiding using up all its resources, he ends by wondering whether man will still be around in the future. It's enough, as he says, to make even God shake his head.

Here is the song:
