Read the passage carefully, then choose the correct answers. 
The search for alternative sources of energy has led in various directions. Many communities are burning garbage and other biological waste products to produce electricity- Converting waste products to gases or oil is also an efficient way to dispose of wastes. Experimental work is being done to derive synthetic fuels from coal, oil shale, and coal tars. But to date, that process has proven expensive. Other experiments are underway to harness power with giant windmills. Geothermal power is also being tested. Some experts expect utility companies to revive hydroelectric power derived from streams and rivers. Fifty years ago hydroelectric power provided one third of the electricity used in theUnited States, but to day it supplies only 4 percents. The oceans are another potential source of energy. Scientists are studying ways to convert the energy of ocean currents, tides, and waves to electricity. Experiments are also underway to make use of temperature differences in ocean water to produce energy.

A.heat from the earth
B.gases in the earth's atmosphere
C.steam that shot up out of the earth
D.water in the ocean, lake, or river

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 35 to 42.
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 develop. 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 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, thought 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 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 the 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 instrument is essential for a child who wants to become an outstanding musician.
The upbringing of highly intelligent children requires________.
A.an expensive education      
B.good musical instruments
C.parental support and encouragement            
D.wealthy and loving parents
