　　The survey about childhood in the Third World shows that the struggle for survival is long and hard. But in the rich world, children can 1 from a different kind of poverty-of the spirit. 2 , one Western country alone now sees 14 000 attempted suicides (自杀) every year by children under 15, and one child 3 five needs psychiatric (心理) advice.

　　There are many good things about 4 in the Third World. Take the close and con-stant relation between children and their par-ents, relatives and neighbours for example. In the West, the very nature of work puts dis-tance between 5 and children. But in most Third World villages mother and father do not go miles away each day to work in of-fices. 6 , the child sees mother and father,relations and neighbours working 7 and often shares in that work.

　　A child 8 in this way learns his or her role through joining in the community's 9 : helping to dig or build, look after ani-mals or babies-rather than 10 playing with water and sand in kindergarten, keeping pets 11 playing with dolls.

　　These children may grow up with a less oppressive sense of space and time than the 12 children. Their sense of days and time has a lot to do with the change of seasons and positions of the sun or the moon in the sky. Children in the rich world, 13 , are pro-vided with a watch as one of the 14 signs of growing up, so that they can 15 along with their parents about being late for school times, meal times, bed times, the times of TV shows...

　　Third World children do not usually 16 to stay indoors, still less in high-rise apartments (公寓). Instead of dangerous road, “keep off the grass” signs and “don't speak to strangers”, there is often a sense of 17 to study and play. Parents can see their children outside rather than observe them 18 from ten floors up.

　　 19 , twelve million children under five still die every year through hunger and disease. But childhood in the Third World is not all 20 .

Plants and animals usually do not live apart, as in many ways they are important to each other. Most green plants can make their own food. The food of other living things, even the food of meat-eating animals, comes directly or indirectly from green plants. For example, some people eat mutton (羊肉); mutton comes from a goat; the goats eat grass. These steps, or links, make up what is called a food chain. Without green plants, all other living things would in time die of starvation.

Plants help animals in other ways too. They furnish homes and shelter for many animals. Many birds, as you know, build their nests in trees. Deer and many other animals use bushes for shelter. And even man depends much upon plants for his shelter. Animals repay some of this debt by helping plants. You may be aware that many insects and some birds do important work for plants by pollinating (授粉) them. You must have also learned how animals often help plants by spreading seeds.

What is waste material for one of these kinds of life is often valuable substance for the other. For example, animals give off carbon dioxide gas when they breathe. When plants make food, they absorb this gas from the air, using the carbon and releasing some of the oxygen back into the air. The oxygen that is released, then, is again supplied to animals. Thus the cycle continues, animals helping plants, and plants helping animals.

All plants and animals have their enemies. Insects eat plants; birds eat insects; other animals kill birds. But here too, animals such as birds and bats help the plants by destroying harmful insects. Many plants and animals are helpful to some living things but are harmful to others. Then there are other rules in nature that act as checks and balances. For example, if there are more animals in a certain area than there is food to support them, some of the animals must migrate or starve. In either case, the number of animals will be reduced until the balance between animals and the available food supply is restored.

These helps and hindrances (障碍) are constantly going on in the plant and animal world to achieve a balance. As long as one living thing is dependent on another, whenever the scales are tipped (使倾斜), nature takes steps to balance the scales again.
