4．专家曾经预测，至少需要一个世纪电脑才能击败人类对手，但结果表明十九年就足够了．（before）The experts predicted that it would be at least one century before the human beings defeated computers，but the results showed that nineteen years was enough．．

分析 The experts predicted that it would be at least one century before the human beings defeated computers，but the results showed that nineteen years was enough．

解答 The experts predicted that it would be at least one century before the human beings defeated computers，but the results showed that nineteen years was enough．
根据句意"专家曾经预测"以及"但结果表明"可知，这是对过去事实的叙述，所以用一般过去时即可．
本句为一个复杂的主从复合句，并两次用到了宾语从句，以及before引导的时间状语从句的运用．at least至少．

点评 对于复合句的灵活运用更能体现出一个学生的能力，适当的在一个句子中使用定语从句，宾语从句，介词短语作状语或者定语等结构．

15．Jack looked up and saw in the distance red and green navigation lights coming towards them and knew it must be a naval patrol（巡逻） boat because of its speed．As the humming of the boat's powerful engines drew closer，Jack bent down．
Jack then let out a frightened cry as the brilliant beam of a searchlight broke the darkness and swept the fishing boat from head to tail．By its reflected light，Jack could clearly see the similar looks on the faces of other bent ones．
Jack knew that if the patrol boat came close enough，its men would surely see the people hidden in the fishing boat．To collect himself，he leaned his head a little so that he could see Derek standing in the head of the boat，holding the tiller（舵柄）．Derek managed to wave back at the patrol boat as if he had not a care in the world．How  imperturbablehe was!
Someone on board the patrol boat switched on a loud speaker and a voice，made harsh and thin by its horn，demanded，"Where are you bound？"
Derek shrugged and shouted back，"Tell me where the fish run and I'll tell you where I am bound．"The noise of idling engines drowned his voice．
"Say again!"barked the speaker．
"Anywhere where there's fish!"Derek shouted back．There was a pause．The boats drifted closer to each other．
"Why aren't you showing navigation lights？"
Jack watched as Derek pretended to look puzzled and leant out over the side as if to see what they said were true．"They must have blown out，"he apologized with a shrug．"I'll light them again as soon as you stop rocking me about like this．"
Aboard the patrol boat，the captain was wondering if it would be worthwhile searching this old fishing boat for stowaways as how many breathing souls could such a shabby boat hide？The radio suddenly cackled．Abruptly，without another word being exchanged，the light went out and the patrol boat started its engines，speeding off into the dark，leaving the fishing boat floating about in the water．
