I. Read the following passage, and decide the statements are true (T) or false (F).

Once there were lots of pandas in the mountain of Western China. Today they are becoming extinct. The reason is that they cannot find enough food. Pandas eat bamboo leaves. They do not like another food. The bamboo grows very slowly. It can take 10 years for a bamboo cane to grow from a seed to a big plant. Some types of bamboo have seeds every 60 years. Pandas must wait many years for their food to grow. While the bamboo is growing, pandas do not have enough leaves to eat.

Farmers are using more and more of the land on the mountain side to grow food for man. The farmers cut down the bamboo. Bamboo leaves become less plentiful. Pandas cannot find enough food to eat. They starve and die.

China and World Wildlife Fund (WWF) are trying to save the panda. In 1979 they began to set up special parks where pandas live. One such park is the Wolong Reserve in Sichuan. The Wolong Reserve has the highest number of pandas in the world. Scientists come here to study the panda’s eating and mating habits. By learning more about the panda’s habits, scientists can save it from extinction.

Conservation is the sensible use and protection of natural resources including plants, animals, mineral deposits, soils, clean water, clean air, and fossil fuels such as coal, petroleum, and natural gas to ensure an adequate supply for future generations.

Natural resources are grouped into two categories, renewable and nonrenewable. A renewable resource is one that may be replaced over time by natural processes, such as fish populations or natural vegetation, or is inexhaustible, such as solar energy. The goal of renewable resource conservation is to ensure that such resources are not consumed faster than they are replaced. Nonrenewable resources are those in limited supply that cannot be replaced or can be replaced only over extremely long periods of time. Nonrenewable resources include fossil fuels and mineral deposits, such as iron ore and gold ore. Conservation activities for nonrenewable resources focus on maintaining an adequate supply of these resources well into the future.

A. To make use of natural resources

III. Read the passage and choose the best answer.

Psychologists have debated a long time about whether a child's upbringing can give it the ability to do outstandingly well. Some think that it is impossible to develop genius and say that it is simply something a person is born with. Others, however, argue that the potential for great achievement can be developed. The truth lies somewhere between these two extremes.

It seems very obvious that being born with the right qualities from gifted parents will increase a child's ability to do well. However, this ability will be fully realized only with the right upbringing and opportunities. As one psychologist says, “To have a fast car, you need both a good engine and fuel”.

Scientists have recently assessed intelligence, achievement, and ability in 50 sets of identical twins that were separated shortly after birth and brought up by different parents. They found that achievement was based on intelligence, and later influenced by the child's environment. One case involving very intelligent twins was quoted. One of the twins received a normal upbringing, and performed well. The other twin, however, was brought up by extremely supportive parents and given every possible opportunity to develop its abilities. That twin, though starting out with the same degree of intelligence as the other, performed even better. This case reflects the general principle of intelligence and ability. The more favorable the environment, the more a child's intelligence and ability are developed. However, there is no link between intelligence and the socioeconomic level of a child's family. In other words, it does not matter how poor or how rich a family is, as this does not affect intelligence.

Gifted people cannot be created by supportive parents, but they can be developed by them. One professor of music said that outstanding musicians usually started two or three years earlier than ordinary performers, often because their parents had recognized their ability. These musicians then needed at least ten years' hard work and training in order to reach the level they were capable of attaining. People who want to have very gifted children are given the following advice:

- Marry an intelligent person.

- Allow children to follow their own interests rather than the interests of the parents.

- Start a child's education early but avoid pushing the child too hard.

- Encourage children to play, for example, playing with musical instruments is essential for a child who wants to become an outstanding musician.
