As people slowly learn to cure diseases, control floods, prevent hunger, and stop wars, fewer people die every year. As a result, the population of the world is becoming larger. In 1925 there were about 2 billion people in the world; today there are over 6 billion.
When the number rises, extra mouths must be fed. New lands must be brought under development, or land already farmed must be made to produce more crops. In some areas the land is so over-developed that it will be difficult to make it provide more crops. In some areas the population is so large that the land is divided into too tiny units to make improvement possible with farming methods. If a large part of this farming population went into industrial work, the land might be farmed much more productively (多产地) with modern methods.
There is now a race for science, technology, and industry to keep the output of food rising faster than the number of people to be fed. New types of crops, which will grow well in bad weather, are being developed, so there are now farms beyond the Arctic Circle in Siberia and North America. Irrigation (灌溉) and dry-farming methods bring poor lands under the plough. Dams hold back the waters of great rivers, which can provide water for the fields in all seasons and provide electric power for new industries. Industrial chemistry provides fertilizer to suit different soils. Every year, some new methods are made to increase or to protect the food of the world.

Personal computers and the Internet give people new choices about how to spend their time.
Some may use this freedom to share less time with certain friends or family members, but new technology will also let them stay in closer touch with those they care most about. I know this from personal experience.
E-mail makes it easy to work at home, which is where I now spend most weekends and evenings. My working hours aren’t necessarily much shorter than they once were but I spend fewer of them at the office. This lets me share more time with my young daughter than I might have if she’d been born before electronic mail became such a practical tool.
The Internet also makes it easy to share thoughts with a group of friends. Say you do something fun see a great movie perhaps-and there are four or five friends who might want to hear about it. If you call each one, you may tire of telling the story.
With E-mail, you just write one note about your experience, at your convenience, and address it to all the friends you think might be interested. They can read your message when they have time, and read only as much as they want to. They can reply at their convenience, and you can read what they have to say at your convenience.
E-mail is also an inexpensive way stay in close touch with people who live far away. More than a few parents use E-mail to keep in touch, even daily touch, with their children off at college.
We just have to keep in mind that computers and the Internet offer another way of staying in touch. They don’t take the place of any of the old ways.

Any mistake made in the printing of a stamp raises its value to stamp collectors. A mistake on one inexpensive postage stamp has made the stamp worth a million and a half times its original value.
The mistake was made more than a hundred years ago in the British colony of Mauritius, a small island in the Indian Ocean. In 1847 an order for stamps was sent to a London printer-Mauritius was to become the fourth country in the world to issue stamps.
Before the order was filled and delivered, a ball was planned at Mauritius’ Government House, and stamps were needed to send out the invitations. A local printer was instructed to copy the design for the stamps. He accidentally inscribed the words “Post Office” instead of “Post Paid” on the several hundred stamps that he printed.
Today there are only twenty-six of these misprinted stamps left fourteen One Penny Orange-Reds and twelve Two Penny Blues. Because of the Two Penny Blue’s rareness and age, collectors have paid as much as ＄16 800 for it.

Today many people say that women have the same chance as men in society. But this was not always so. In the past, women all over the world had to fight to get the same chance as men in education and jobs. Many people said that women should not receive much education because they would not do as well as men when they went to work.
One woman who showed that women should have the same chance was Marie, a scientist. In the 1800s scientists knew that a metal, uranium, gave off radiation. They also knew how much radiation came from his element. But they didn’t know what this radiation was like; they wondered why and how uranium gave off radiation. Marie Curie set out to answer these questions. In one of her experiments she was studying a certain material which, she knew, contained uranium, But it gave off 4 times as much radiation as usually does. What could explain this fact? Marie Curie thought that there must be another source of radiation in this material.
In 1898 Marie Curie set out to find out this new source of radiation, which she named “radium”. Her husband, who was also a scientist, helped her. They set up a laboratory in an old building behind a school. For four years Curies searched, doing many experiments, And one morning in 1902 Marie found the source of the radiation.
Marie Curie proved to the world that there was element that gave off radiation. And she also proved to the world that, if women are given truly equal chance, they can really help society.

It is interesting how NASA(美国航空航天管理局)chose their astronauts for landing them on the moon. They chose men 26 the age of twenty and thirty-five. There were about fifty of them, Many were 27 air pilots. 28 were scientists with two or three degrees. NASA telephoned each man they were going to choose; told him the plans and the 29 they might get in. They then asked him if he was willing to be trained as an astronaut. “How could any man 30 such an exciting job?” One of them said, “Dangerous? Of course. It’s dangerous 31 most exciting”
The health and physical condition of 32 was, of course, very necessary. 33 those in very good health and physical condition were chosen.
While being trained to be astronauts. They went through many 34 . They studied the star and the moon, and they also studied geology, the science of rocks. This was necessary 35 astronauts would have to look for rocks on the moon. They would try to find rocks which might help to tell the 36 of the moon. They were all 37 to fly in helicopters （直升飞机）。These helicopters landed 38 down to give them some experience of the way the spaceship would 39 land on the moon , They were also taught the 40 facts about the conditions in space. They learnt all the technical details of the spaceships and rockets. They visited the scientists and engineers who 41 them. They visited the factories where they were 42. They learnt how every 43 of a space-ship and its instruments work. They also learnt every detail of ground-control 44 .
In a word, to be chosen as an astronaut. One must be in good health, 45 in science and good at piloting.
