Hardly a week goes by without some advance in technology that would have seemed in- credible 50 years ago. And we can expect the rate of change to accelerate rather than slow down within our lifetime. The developments in technology are bound to have a dramatic effect on the future of work. By 2010, new technology will have revolutionized communications. People will be transmitting messages down telephone lines that previously would have been sent by post. Not only postmen but also clerks and secretaries will vanish in a paper-free society. All the routine tasks they perform. will be carried on a tiny silicon chip so that they will be as obsolete as the horse and cart after the invention of the motor car. One change will make thou-sands, if not millions, redundant.
Even people in traditional professions, where expert knowledge has been the key, are unlikely to escape the effects of new technology. Instead of going to a solicitor, you might go to a computer which is programmed with all the most up-to-date legal information. Doctors, too, will find that an electronic competitor will be able to carry out a much quicker and more accurate diagnosis and recommend more efficient courses of treatment. In education, teachers will be largely replaced by teaching machines far more knowledgeable than any human being. Most learning will take place in the home via video conferencing. Children will still go to school though, until another place is created where they can make friends and develop social skills.
What can we do to avoid the threat of unemployment？ We shouldn't hide our heads in the sand. Unions will try to stop change but they will be fighting a losing battle. People should get computer literate as this just might save them from professional extinction. After all, there will be a few jobs left in law, education and medicine for those few individuals who are capable of writing and programming the software of the future. Strangely enough, there will still be jobs like rubbish collection and cleaning as it is tough to programme tasks which are largely unpredictable.
According to the writer, the rate of change in technology ______.
A．will remain the same.
B．will slow down
C．will speed up
D．can not be predicted

Directions: Read the following three texts. Answer the questions on each text by choosing A, B, C or D. Mark your answers on ANSWER SHEET 1.
In the earliest stages of man's development he had no more need of money than animals. He was content with very simple forms of shelter, made his own rough tools and weapons and could provide food and clothing for himself and his family from natural materials around him. As he became more civilized, however, he began to want better shelter, more efficient tools and weapons, and more comfortable and more lasting clothing than could be provided by his own neighborhood or by the work of his own unskilled hands. For these things he had to turn to the skilled people Such as smiths, leather workers or carpenters who were springing up everywhere. It was then that the question of payment arose.
At first he got what he wanted by a simple process of exchange. The smith who had not the time to look after land or cattle was glad to take meat or grain from the farmer in exchange for an axe or a plough. But as more and more goods which had no fixed exchange value came on the market, exchange became too complicated to be satisfactory. Another problem arose when those who made things wanted to get stocks of wood or leather, or iron, but had nothing to offer in exchange until their finished goods were ready.
Thus the difficulties of exchange led by degrees to the invention of money. In some countries, easily handled things like seeds or shells were given a certain value and the farmers, instead of paying the smith for a new axe by giving him some meat or grain, gave him so many shells. If the smith had any shells left when he had bought his food, he could get stocks of the raw materials of his trade. In some countries quite large things such as cows or camels or even big flat stones were used for trade. Later, pieces of metal, bearing values according to the rarity of the metal and the size of the pieces, or coins were used. Money as we know it had arrived.
Early men didn't have to use money because ______.
A．they had simple forms of shelter
B．they had to provide food and clothing for themselves
C．they had no enough natural resources around them
D．they could meet basic needs through their own efforts
