Imagine aguitar so tiny that you can ’t seeit with the human eye, but you can hearsound when its strings are pulled. Some people say the future is big, but when it comes to technology, theworld is getting smaller. 

Nanotechnology( 纳米技术 )is the science that deals with doing things in a very small way,and it is being studied and developed all over the world. Micro-machines too small to been seenby the eye are being designed to do many things. And these machines no larger than in diameterthan a human hair, are extremely powerful. Many scientists say nanotechnology will produce thenext industrial revolution( 工业革命 ). 

Nano comes from the Greek word dwarf . A nanometer is one-billion of a meter, The periodof the end of this sentence can contain about 100 micrometers, which in equal to 100,000nanometers.To understandthis new technology, we have to get rid of the normal ideas of size andstrength. 

Minute( 微 小 的 ) robots , called “ nanorobots ” are being developed in the revolutionizemanufacturing. Instead of cars being produced on assembling line, for example, scientist predictthat carscan be built in a giant container into which raw material and machines have beenplaced.Thousands of nanorobots will direct the processandtell the machine what to do. 

Micro-machines can also be used to make our environment safer. Today, poison chemicals arestored in containers or transported by trucks or trains. This is sometimes result in dangerous spills.But with nanotechnology, manufacturers could have their own tiny chemical factories. Theproduce would be no bigger than a sugar cube and would manufacture exactly the amount ofchemicals neededat the moment. No chemicals would needto be stored. The workplace would besafer,and the environment would be cleaner.

But finally, the loss of forests may have an effect on the climate of our planet.

In industrial countries, people are using more and more wood for paper,furniture and houses.

In many area,people dependon wood to cook their food.

The destruction of forests affects first the people who usedto live there.

Mary was born and brought up in American, but she speaks Chinese very fluently____________________(好像就是个土生土长的中国人似的） .

(66)There is nothing new about people cutting down trees. In ancient times, Greece, Italy,and Great Britain were covered with forests. Over the centuries those forests were gradually cutback, until now almost nothing is left. 

Today, trees are being cut down more rapidly. A major cause of present destruction is theworldwide demand for wood. (67) In industrial countries, people are using more and more woodfor paper, furniture and houses.There is not enough wood in these countries, therefore they havebegun taking wood from the forest of Asia, Africa and other countries. 

Wood is also in great demand in developing countries. (68) In many area, people depend onwood to cook their food. As the population grows, the need for wood grows. But when too manytreesare cut down, forests are destroyed. In reality, there is usually no chance to grow back. In thisway, many millions of acresof forestsare destroyed every year. 

(69)The destruction of forests affects first the people who usedto live there. It also hasothereffects far way. For example, trees help to absorb heavy rains. When the trees are cut down, therain pours all at onceinto the river. 

(70)But finally, the loss of forests may have an effect on the climate of our planet. Togetherwith increasing pollution, it could causetemperature to rise, and the climate will change aroundthe world. No one would know exactly what effects the world have on our life. For many peoplethe effects would probably be destructive. 

66、 There is nothing new about people cutting down trees.
