The importance of environment in determining an individual's intelligence can be demonstrated by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, end their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate homes. Peter was reared by parents of low intelligence in an isolated community with poor educational opportunities. Mark, on the other hand, was raised in the home of rich parents who had been to college. He was read to as a child, sent to a good school, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Peter's score was 85, well below the level he might have attained if reared under average conditions. Mark' s score was 125, twenty-five points above the average and fully forty points higher than his identical brother. Given equal opportunities, the twins would have tested at roughly the same level. (38) A．Children reared under average conditions possess average intelligence. B．Lack of opportunity prevents the growth of intelligence. C．An individual's intelligence is determined chiefly by his environment. D．Changes of environment produce changes in the brain structure.

Sufficient buoyancy （浮力）to support the wearer should be retained by the life preserver after 48 hours in the water, and it should be reliable even after long period of storage.Thus it should be made of materials resistant to sunlight, gasoline, and oils, and it should be not easily set on fire.The position in which the life preserver will support a person who jumps or falls into the water is most important, as is its tendency to turn the wearer in the water from a face-down position to an upright or slightly backward position, with his face clear of the water, even when the wearer is exhausted or unconscious. The method of adjustment to the body should be simple, and self-evident to uninitiated persons even in the dark under the confused conditions, which follow a disaster.Thus, the life preserver should be reversible that it is nearly impossible to get it on wrong.Catches, straps, and ties should be kept to a minimum.In addition, the life preserver must be adjustable to the wide variety of shapes and sizes of wearers, since this greatly affects the position of floating and the self-righting qualities.A suitable life preserver should also be comfortable to wear at all times, in and out of the water, not so heavy as to encourage to take it off on shipboard while the ship is in danger, nor so burdensome that it hinders a person in the water while trying to swim. 1.The passage is mainly about（）. A.the uses of life preservers B.the design of life preservers C.the materials for life preservers D.the buoyancy of life preservers 2.According to the passage, a life preserver should be first of all （）. A.adjustableB.comfortableC.self-evidentD.self-righting 3.United States Coast Guard does NOT require the life preserver to be made （）. A.with as few strings as possible B.capable of being worn on both sides C.according to each wearer's size D.comfortable and light to wear 4.By “the uninitiated individual” （Para）1, Line.4.the author refers to the person （）. A.who has not been instructed how to use a life preserver B.who has a little experience in using a life preserver C.who uses a life preserver without permission D.who becomes nervous before a disaster 5.What would happen if a person were supported by the life preserver in a wrong position？ A.The waves would move him backwards. B.The water would choke him. C.He would immediately sink to the bottom. D.He would be exhausted or unconscious.
