e supermarkets here are full of them，aren't they？ (19)Perhaps that is why our food is not very tasty．as you may have found out already．

W：But frozen foods are convenient and handy．aren't they？ Just think of all tile tedious work we would have to do in the kitchen if it weren't for frozen foods and the like．

M：Yes．that's true! (20)But you spend much more time cooking and preparing meals in your country than we do in Britain．don't you？

W：Yes．I suppose we do．You make less fuss about food than we do．In my own country，we have two big meals a day，that is，lunch and dinner，and we spend a lot of time preparing them．(21)Here in Britain，you have only one big meal a day, apart from breakfast and lunch snack, and you spend much less time preparing it．

M：Yes，but we're just as fond of good and delicious food as you are．

W：Well, you certainly don't show it!

M：We do fuss about our meals sometimes，and remenber，we like to eat out on special occasions，such as weekend evenings．birthday parties and other celebrations．London is full of foreign restaurants where you can get all the exotic dishes of the world．You must come out with us one evening，Lisa．

W：Thank you very much，I'd love to．That's what I like about London．(22)There's always so much to see and do!I think I made a wise decision when I chose to live and study in London．

of the labor force, the increase in output per man-hour, and the growth of total demand for goods and services. Changes in the average hours of work enter in exactly parallel fashion but have been quantitatively less significant. As productivity rises, less labor is required per dollar of national product, or more goods and services can be produced with the same number of goods. If output does not grow, employment will certainly fall; if production increases more rapidly than productivity (less any decline in average hours worked)employment must rise. But the labor force grows, too. Unless gross national product(total final expenditure for goods and services corrected for price changes) rises more rapidly than the sum of productivity increase and labor force growth (again modified for any change in hours of work), the increase in employment will be inadequate to absorb the growth in the labor force. Inevitably the unemployment rate will increase. Only when total production expands faster than the rate of labor force growth plus the rate of productivity increase and minus the rate at which average annual hours fall does the unemployment rate fall. Increases in productivity were more important than growth of the labor force as sources of the wide gains in output experienced in the period from the end of the war to the mid-sixties. These increases in potential production simply were not matched by increases in demand adequate to maintain steady full employment.

Except for the recession years of 1949, 1954, and 1958, the rate of economic growth exceeded the rate of productivity increase. However, in the late 1950s productivity and labor force were increasing more rapidly than usual, while the growth of output was slower than usual. This accounted for the change in employment rates.

But if part of the national purpose is to reduce and contain unemployment, arithmetic is not enough. We must know which of the basic factors we can control and which we wish to control. Unemployment would have risen more slowly or fallen more rapidly if productivity had in creased more slowly, or the labor force had increased more slowly, or the hours of work had fallen more steeply, or total output had grown more rapidly. These are not independent factors, however, and a change in any of them might have caused change in the other.

A society can choose to reduce the growth of productivity, and it can probably find ways to frustrate its own creativity. However, while a reduction in the growth of productivity at the expense of potential output might result in higher employment in the short run, the long-run effect on the national interest would be disastrous.

We must also give consideration to the fact that hidden beneath national averages is continuous movement into, out of, between, and within labor markets. For example, 15 years ago, the average number of persons in the labor force was 74 million, with about 70 million employed and 3.9 million unemployed. Yet 14 million experienced some term or unemployment in that year. Some were new entrants to the labor fore; others were laid off temporarily, the remainder were those who were permanently or indefinitely severed from their jobs. Thus, the average number unemployed during a year understates the actual volume of involunatary displacement that occurs.

High unemployment is not an inevitable result of the pace of technological change but the consequence of passive public policy. We can anticipate a moderate increase in the labor force accompained by a slow and irregular decline in hours or work. It follows that the output of the economy--and the aggregate demand to buy it--must grow by more than 4 percent a year just to prevent the unemployment rate from rising, and by even more if the unemployment rate is to fall further. Yet our

A．productivity rises at the same rate as growth of the labor force

B．productivity and labor force increase at a greater rate than output

C．output exceeds productivity

D．rate of economic growth is less than the number of man-hours required

who had just returned from abroad. He had rented a cottage in the country, although he rarely spent much time there. We understood the reason for this after our arrival: the cottage had no comfortable furniture in it, many of the windows were broken and the roof leaked, making the whole house damp. On our first evening, we sat around the fire after supper listening to the stories which our uncle had to tell of his many adventures in distant countries. I was so tired after the long train journey that I would have preferred to go to bed; but I could not bear to miss any of my uncle’s exciting tales. He was just in the middle of describing a rather terrifying experience he had once had when there was a loud crash from the bedroom above, the one where my brother and I were going to sleep. “It sounds as if the roof has fallen in!” exclaimed my uncle, with a loud laugh. When we got to the top of the stairs and opened the bedroom door, we could see nothing at first because of the thick clouds of dust which filled the room. When the dust began to clear, a strange sight met our eyes. A large part of the ceiling had collapsed, falling right on to the pillow of my bed. I was glad that I had stayed up late to listen to my uncle’s stories, otherwise I should certainly have been seriously injured, perhaps killed. That night we all slept on the floor to the sitting room downstairs, not wishing to risk our lives by sleeping under a roof which might at any moment collapse on our heads. We left for London the very next morning and my uncle gave up his cottage in the country. This was not the kind of adventure he cared for either!
