A very important world problem is the increasing number of people who actually inhabit thi

s planet. The limited amount of land and land resources will soon be unable to support the huge population if it continues to grow at its present rate.

So why is this huge increase in population taking place？ It is really due to the spread of the knowledge and practice of what is becoming known as "Death Control". You have no doubt heard of the term "Birth Control". "Death Control" is something rather different. It recognises the work of the doctors and scientists who now keep alive people who, not very long ago, would have died of a variety of then incurable diseases. Through a wide variety of technological innovations that include farming methods and the control of deadly diseases, we have found ways to reduce the rate at which we die. However, this success is the very cause of the greatest threat to mankind.

If we examine the amount of land available for this ever-increasing population, we begin to see the problem. If everyone on the planet had an equal share of land, we would each have about 50,000 square metres. This figure seems to be quite encouraging until we examine the amount of usable land we actually have. More than three-fifths of the worlds land cannot produce food.

Obviously, with so little land to support us, we should be taking great care not to reduce it further. But we are not! Instead, we are consuming its "capital" — its nonrenewable fossil fuels and other mineral deposits that took millions of years to form. but which are now being destroyed in decades. We are also doing the same with other vital resources not usually thought of as being nonrenewable such as fertile soils, groundwater and the millions of other species that share the earth with us.

It is a very common belief that the problems of the population explosion are caused mainly by poor people living in poor countries who do not know enough to limit their reproduction. This is not true. The actual number of people in an area is not as important as the effect they have on nature. Developing countries do have an effect on their environment, but it is the populations of richer countries that have a far greater impact on the earth as a whole.

According to the passage, what contributes to the population increase？

A．Human beings" ignorance.

B．The failure of "Birth Control".

C．The success of "Death Control".

D．Technological innovations.

Although the practice of the old Roman religion disappeared many centuries ago, some tra

ces of the Roman gods are still present in our daily vocabulary. The names of the Roman sun god, Sol, and the moon goddess, Luna, are used frequently in our language The word solar describes anything pertaining to the sun, and lunar anything pertaining to the moon. For example, the sun and the planets circling it are called the solar system. The period of time in which the earth circles the sun once is a solar year. The moon takes one lunar month to circle the earth. A lunar year of twelve lunar months is eleven days shorter than a solar year. In some cases our language shows how these heavenly bodies affect us directly. A room or place for sunbathing is often called a solarium. We get our word parasol from the Italian word meaning " a guard against the sun." For many centuries it was believed that the moon affected people who were mentally ill. For this reason persons who were mentally ill were often referred to as lunatics.

Natural ResourcesThroughout history, people have often selected where they want to live

Natural Resources

Throughout history, people have often selected where they want to live based on the natural resources that are available in the area.26 Some of these resources include water, food sources such as fruits and vegetables, and animals that can be caught or hunted.

A region’s natural resources determine the way of life of its people.27 |On the other hand，poor soil will either send people looking for better places, or attract people with other purposes for the land, such as setting up businesses or factories.

28 People who wish to make a living as fishermen can do so by the pcean, but cannot do so in the desert.Desert people have many traditional and |mique foods, which cannot be found in the forest.Each area attracts people based on their interests and purposes.

Areas that have rich water resources will naturally have more people, frraditionally, villages，towns and cities built near water have been the most luccessful.People there are able to use the water resources to meet their daily lieeds.29 Places that are hard to reach，such as high mountains or dry Beserts, will have fewer people living in them.

30 For too long, people have destroyed natural resources, using up those [resources that cannot be easily replaced.On the earth, we are lucky to have many resources that are renewable, such as sun, wind, water, and trees.As more and more focus is placed on the use of renewable resources, it will become easier to |＞rotect our planet from further harm.

A.It is easy to find new resources in nature.

B .Renewable resources are those that can be replaced easily.

c.While you may not think of oceans as natural resources, they are.

D .for example, regions with rich soil can support fanning societies.

E .They can also use the water to help them move goods to other areas.

F.Natural resources are useful to people, and they come from the earth.
