Population tends to grow at an exponential(指数的)rate. This means that they progressively double. As an example of this type of growth rate, take one penny and double every day for one month. After the first week, you would have only 64 cents, but after the fourth week you would have over a million dollars.
This helps explain why the population has come on "all of a sudden". It took from the beginning of human life to the year 1830 for the population of the earth to reach one billion. That repents(缓慢进行)a time span of at least two million years. Then it took from 1830 to 1930 for world population to reach 2 billion. The next billion was added by 1960, only thirty years, and in 1975 world population reached 4 billion, which is another billion people in only fifteen years.
World population is increasing at a rate of 9000 per hour, 220000 per day, and 80 million per year. This is not only due to higher birth rate, but to lower death rate as well. The number of births has not declined at the same rate as the number of deaths.
Some countries, such as Columbia, Thailand, Morocco, Costa Rica, and the Philippines, are doubling their population about every twenty-one years, with a growth rate of 3.3% a year or more. The United States is doubling its population about very eighty-seven years, with a rate of 0.8% per year. Every time a population doubles, the country involved needs twice as much of everything, including hospitals, schools, resources, food and medicines to care for its people. It is easy to see that this is very difficult to achieve for the more rapidly growing countries.
This passage chiefly discusses______.
A．the growth of world population
B．one type of the exponential rate
C．the population problem of more rapidly growing countries
D．the possible ways of dealing with the rapid population growth
There is no doubt that something of this kind will happen. The shorter working week, longer holidays, earlier retirement, job-sharing -- these and other ways of reducing the amount of time people spend on their jobs -- are certainly likely to spread. A mix of part-time paid work and part-time unpaid work is likely to become a much more common work pattern than today, and a flexi-life pattern of work -- involving paid employment at certain stages of life, but not at others -- will become widespread. But it is surely unrealistic to assume that this will make it possible to restore full employment as the dominant form. of work.
In the first place, so long as employment remains the overwhelmingly important form. of work and source of income for most people that it is today, it is very difficult to see how reductions in employees' working time can take place on a scale sufficiently large and at a pace sufficiently fast to make it possible to share out the available paid employment to everyone who wants it. Such negotiations as there have recently been, for example in Britain and Germany, about the possibility of introducing a 35-hour working week, have highlighted some of the difficulties. But, secondly, if changes of this kind were to take place at a pace and on a scale sufficient to make it possible to share employment among all who wanted it, the resulting situation --in which most people would not be working in their jobs for more than two or three short days a week -- could hardly continue to be one in which employment was still regarded as the only truly valid form. of work. There would be so many people spending so much of their time on other activities, including other forms of useful work, that the primacy of employment would be bound to be called into question, at least to some extent.
The author uses the negotiations in Britain and Germany as an example to
A．support reductions in employees' working time.
B．indicate employees are unwilling to share jobs.
C．prove the possibility of sharing paid employment.
D．show that employment will lose its dominance.

Every year for more than a decade I"ve gone with some good male friends to the music festi- val. Women are not invited， but they do prepare a picnic for our trip. The better the food， the more likely we are to continue our annual tradition and give them peace at least one week out of the year.
When we"re not eating， we sit around in circles and talk about manly stuff: women， mostly.After years of this special journey I have figured out women are different from us， especially when it comes to how we communicate. Women don"t need to manufacture reasons to chat， but guys need excuses like outings or organized events.
And I"ve noticed that when women are in groups there can be several conversations going on at once. When men are in a group， one man talks， and everybody else listens. It"s like bluegrass jamming in a way; one musician plays the lead， and the rest try to follow.
I"ve had more heartfelt conversations with other men at the festival than I"ve had at any other time in my life， partly because there are no women there， and partly because we"re all a little drunk. It was males bonding over whatever parts we still had left. The festival is also the only place I"ve ever cried in front of other men.
As the years have slipped by， some in our group have lost parents and grandparents， some have divorced， and others have changed careers， not always on purpose. It seems that every year something distressing has happened to at least one member of our crew， and the rest of us are there to listen and offer support.
I hope that this column can offer some comfort to women: if your man heads out on a bowling or poker night with the guys， be happy. Chances are good he"s not fleeing you and the kids， but he"s running toward the conversations he can only have with other men， and he"ll come home the better for it.
It is implied in the first paragraph that 查看材料
A.the trip is a relief for both men and women________
B.the trip will continue in spite of everything
C.the quality of the picnic needs improvement
D.the women can rarely get peace themselves
The summer holidays are the best part of the year for most children.The weather is usually good, so that one can spend most of one’s time playing in the garden or, if one lives in the country, out in the woods and fields.Even if one lives in a big town, one can usually go to a park to play.
The best place for a summer holiday, however, is the seaside.Some children are lucky enough to live near the sea, but for the others who do not, a week or two at one of the big seaside towns is something which they will talk about for the whole of the following year.
In England, it is not only the rich who can take their children to the seaside; if a factory worker or a bus driver, a street cleaner or a waiter wants to take his wife and children to Southend or Margate, Blackpool or Clacton, he is usually quite able to do so.
Now, what is it that children like so much about the seaside？ I think it is the sand, sea and sun more than any other things.Of course, there are lots of new things to see, nice things to eat, and exciting things to do, but it is the feeling of sand under one’s feet, of salt water on one’s skin, and of the warm sun on one’s back that makes the seaside what it is.
1.Summer holidays start _________.
A.with July
B.as soon as the examinations are over
C.in mid-June
D.in August
2.After the examination, all pupils leave for home ________.

Questions 31 to 35 are based on the following passage:
Designing a lens can be compared to playing chess. In chess a player tries to trap his opponent's king in a series of moves. In creating a lens a lens designer attempts to “trap” light by forcing all the rays arising from a single point in the subject to focus on a single point in the image, as a consequence of their passing through a series of transparent(透明的) elements with precisely curved surfaces. Since in both cases the ultimate goal and the means by which it can be attained are known, one is tempted to think there will be a single best decision at any point along the way. The number of possible consequences flowing from any one decision is so large, however, as to bevirtually, if not actually, infinite. Therefore in lens design, as inchess, perfect solutions to a problem are beyond reach. Although this article will be concerned only with the design of photographic lenses, the same principles apply to all lenses.
The lens designer has one enormous advantage over the chess player: the designer is free to call on any available source of help to guide him through the staggering number of possibilities. Most of that help once came from mathematics and physics, but recently computer technology, information theory,chemistry, industrial engineering and psychophysics have all contributed to making the lens designer's job immeasurably more productive. Some of the lenses on the market today were inconceivable a decade ago. Others whose design is as much as a century old can now be mass produced at low cost. With the development of automatic production methods, lenses are made by the millions, both out of glass and out of plastics. Today's lenses are better than the best lenses used by the great photographers of the past.Moreover, their price may lower, in spite of the fact that 19th century craftsmen worked for only a few dollars a week and today's lenses are more complex. The lens designer cannot fail to be grateful for the science and technology that have made his work easier and his creations more widely available, but he is also humbled: it is no longer practical for a fine photographic lens to be designed from beginning to end by a single human mind.
31.Lens design and chess playing are similar in that ____.
A) the final goal and the means by which it can be reached are known
B) perfect solutions to a problem can be found
C) any one decision at any point along the way to the goal can bring numerous possible results
D) both A and C
32.The final goal of designing a lens is ____.
A) to trap the opponent's lenses
B) to focus light with lenses
C) to hand make lenses at low cost
D) to reflect light by means of curved surfaces
33.After the passage the author will talk about ____.
A) the principles of designing lenses
B) techniques of making contact lenses
C) the design of photographic lenses
D) styles of lenses
34.Which of the following words cannot be used to describe today's lenses？
A) More delicate. B) Cheaper. C) Numerous. D) Unpopular.
35.Lens designers today ____.
A) have a large source of help to fall back on B) receive a low salary
C) are less respectable than those of the past D) are not decisive in the lens design
