| The growth of population during the
past few centuries is no proof that population will continue to grow straight
upward toward infinity and doom. On the contrary, demographic history offers
evidence that population growth has not been at all constant. According to
paleo-ecologist Edward Deevey, the past million years show three momentous
changes. The first, a rapid increase in population around one million B. C.,
followed the innovations of tool-making and tool-using. But when the new
power from the use of tools had been exploited, the rate of world population
growth fell and became almost stable. The next rapid jump in population started perhaps 10,000 years ago, when men began to keep herds, plow and plant the earth. Once again when initial productivity gains had been absorbed, the rate of population growth abated. These two episodes suggest tha A. Productivity will rise. B. Productivity will receive no impact. C. Population growth will slow down. D. Population growth will become accelerated. [单项选择]下列财产中，不得作为抵押财产的有( )。

Finding a Job
At sixteen Ron Mackie might have stayed at school,but the future called to him excitedly.“Get out of the classroom into a job,”it said,and Ron obeyed.His father,supporting the dcci-sion,found a place for him in a supermarket.“You're lucky,Ron,”he said.“For every boy with a job these days,there's a dozen without.” So Ron joined the working world at twenty pounds a week. For a year he spent his days filling shelves with tins of food.By the end of that time he was looking back on his school days as a time of great variety and satisfaction.He searched for an in-terest in his work,with little success. One fine day instead of going to work Ron got a lift on a lorry going south.With nine pounds in his pocket,a full heart and a great longing for the sea,he set out to make a better way for him-self. That evening,in Bournemouth,he had a sandwich and a drink in a cafe run by an elderly man and his wife.Before he had finished the sandwich,the woman had taken him on for the rest of the summer,at twenty pounds a week,a room upstairs and three meals a day.The ease and speed of it rather took Ron's breath away.At quiet times Ron had to check the old man's arithme- tic in the records of the business. At the end of the season,he stayed on the coast. He was again surprised how straightforward it was for a boy of seventeen to make a living.He worked in shops mostly,but once he took a job in a hotel for three weeks.Late in October he was taken on by the sick manager of a shoe shop. Ron soon found himself in charge there;he was the only one who could keep the books. Why did Ron leave the supermarket? A.He knew he would find work in Bournemouth. B.He took a job as a lorry driver. C.He gave up the job because he felt unwell. D.He wanted to work at the seaside. [判断题]调压装置上的安全断阀复位前安全切断阀前后压力不平衡，也可以复位。
