　　eighty percent of cancer is related to the diet ，as well,especially cancer of colon” 也与文意不符，不是所有癌症 都是食物引发的。A 选项说所有的食物都适合食用，与文章第一段第一句话“at the same time,made many food

　　unfit to eat.” 意思不符，因此此题选 D

　　Passage 2

　　We are leaving the Industrial Age,when nation took pride in building the biggest machines possible,and entering the Tiny Tech Age,where power and prosperity will get to those who make machines smaller and smaller.In this world,the rules of the ‘big’ world do not always apply ---insects walk on water and ants carry many times their own weight.Those who work in micromachine labs must wear surgical masks.lest they breathe in the tiny devices from work surfaces.

　　Tiny technologies are a key to the future of robot.The old science-fiction notion of a robot pictured a large machine that mimicked human form and thinking. But a visitor to the Artificial Intelligence Laboratory at the Massachusetts Institute of Technologyin Cambridge gains a truer glimpse of our robotic future,

　　Out of the corner of his eye,the visitor sees something zip across the floor and duck under a chair.It is Squirt,a robot scarcely a cubic inch in size,designed not to think but to react in preprogrammed ways to stimuli.Turn on the lights or make a noise and Squirt quickly runs for the nearest dark place it “sees”.Turn off the light and Squirt comes out a few minutes later in the direction from which its twin-microphone “ cars” last picked up noise.

　　From M.I.T.scientists,the idea is to invent micro-robots that are fast and cheap and that work without human supervision.Squirt developer Anita Flynn foresees micromachine servants mass-produced so cheaply that when one finally wears out ,you’ll be able to throw it away and by a new one.

　　As explorers in this strange microworld,scientists and engineers are seeking new ways to build machines in other fields such as medicine,manufacturing and aerospace.But the use of micromachines is not limited to

　　specialized fields alone.You’ll be able to buy a “smart” car onboard microcomputer to adjust the engine as temperature changes.Micromachines can make your home “ smart” too.They will tell your air conditioner how to adjust themselves for efficiency and minimal pollution.There are also microsensor wrist watcher that monitor heart rate,pulse and blood preesure.By “ thinking small” ,scientists and dreamers are enlarging and enriching the future all of us.

　　这篇文章主要在谈微电子科技的发展。

　　56.In Paragraph 2,the word” mimicked”is closest in meaing to____?

　　A.imitate B .enjoy C .understand D.study

　　此题是词义理解题，我们在文章中锁定该词的位置， “The old science-fiction notion of a robot pictured a large machine that mimicked human form and thinking.” A imitate 模仿，B enjoy 喜欢，使喜悦 C understand 理

　　0 D 学习，文意是机器人是大的机器，去 mimicked 人类的行为和思想，A 最符合文意。

　　57.”Squirt” has all the following characteristics EXCEPT_____?

　　A.cheap B . Tiny C .smart D. Fast
