2.D Artificial是“人工”的意思，intelligence是“智能”的意思。另外从文中得知，机器人使用artificial intelligence能够进行与人类类似的推理分析等活动，因此可知它是一种类似人类智能的计算机程序。
3.A 最后一段讲机器人的发展方向是更加智能，能够自己判断并修正行为，而不仅仅是完成重复性的工作。
4.B 文章开头的时候作者让读者描述他们脑海中的机器人概念，并随后介绍了实际的机器人是怎样的，因此选择B选项。
5.D 从humanoid的词根human可看出这个词是形容与人类有关的特征。另外根据文章对这个词的描述可以得出这个词是表示和人类类似的特征，不管是外形上，还是行为方式上。
第九篇 Lightening Strikes
Three years ago a bolt of lightning all but destroyed Lyn Miller’s house in Aberdeen—with her two children inside. “There was a huge
rainstorm,” she says, recalling the terrifying experience. “My brother and I were outside desperately working to stop floodwater from coming in the house. Suddenly I was thrown to the ground by an enormous bang. ____1____ The door was blocked by rubble, but we forced our way in and found the children, thankfully unharmed. Later I was told to be struck by lightning is a chance in a million.” In fact, it’s calculated at one chance in 600,000. Even so, Dr Mark Keys of AER Technology, an organisation that
monitors the effects of lightning, thinks you should be sensible. “I wouldn’t go out in a storm—but then I’m quite a careful person.” He advises anyone who is unlucky enough to be caught in a storm to get down on the ground and curl up into a ball, making yourself as small as possible.
Lightning is one of nature’s most awesome displays of sheer power. ____2____ 250 years ago, Benjamin Franklin, the American scientist and statesman，proved that lightning is a form of electricity, but scientists still lack a complete understanding of how it works.
____3____ Positive electrical charges streaming upwards from trees or church spires may glow and make a buzzing noise, and people’s hair can stand on end. And if you fear lightning, you’ll be glad to know that a company in America has manufactured a hand-held lightning detector which can detect it up to 70 kms away, sound a warning tone and monitor the storm’s approach.
Nancy Wilder was playing golf at a club in Surrey when she was hit by a bolt of lightning. Mrs Wilder’s heart stopped beating, but she was resuscitated and, after a few days in hospital, where she was treated for bums to her head, hands and feet, she was pronounced fit again. Since that time，she has been a strictly fair weather golfer1. ____4____ The best place to be is inside a car!
The largest number of people to be struck by lightning at one time was in September 1995 when 17 players on a football pitch were hit
simultaneously. The most extraordinary aspect of the strike was the fact that 11 of the victims—seven adults and four children—had burn patterns of tiny holes at 3 centimetre intervals on each toe and around the soles of their feet.
Harold Deal, a retired electrician from South Carolina, USA, was struck by lightning 26 years ago. He was apparently unhurt, but it later emerged that the strike had damaged the part of the brain which controls the sensation of temperature. ____5____
Animals are victims of lightning too2.Hundreds of cows and sheep are killed every year, largely because they go under trees. In East Anglia in 1918, 504 sheep were killed instantaneously by the same bolt of lightning that hit the ground and travelled through the entire flock. Lightning is also
responsible for starting more than 10,000 forest fires each year world-wide.
