Passage One Among all the animals, the ape is most like human beings. Both people and apes have the similar brain structure, the similar nerve system, and the similar kind of blood. There are four kinds of apes: the chimpanzee ( 黑猩猩 ), the orangutan ( 猩猩), the gorilla (大猩猩), and the gibbon (长臂猿). They live in the deep forests and warm tropical regions of Africa and of Southeast Asia, including Indonesia. All apes are covered with brown, reddish-brown, or black hair everywhere on their bodies except their faces, feet, and hands. Their hands each have four fingers and a thumb that helps them grip things the way our thumbs help us. But they also have a thumb on each foot instead of a big toe. Thus they can hold things with their feet also. Having short, weak legs, apes do not walk on the ground very much. However, their arms are very strong. This enables them to swing from branches and travel very quickly from tree to tree. These animals live in small family groups that move from place to place in search of vegetables and fruits. They also eat eggs, small animals, nuts, and insects. When they are tired, they build nests in the trees. But they rarely sleep there for more than a night or two. Than they move on to look for more food. There are some differences among the following three kinds of apes. The gibbon is never more than three feet high and weighs only about fourteen pounds. The gorilla grows to be six feet tall and weighs up to 600 pounds. The orangutan is smaller than the gorilla. It stands three to five feet tall and weighs up to 200 pounds. Chimpanzees are the smartest of all apes. They can be taught to sit at a table and eat, to dress themselves, and to do things that human children can do. The last paragraph tells us that ______.

Passage Two Videodisc holds great promise of helping to meet the needs of American schoolchildren who have problems seeing, hearing, speaking, or socializing. Almost eleven percent of the students aged 3～21 in this country have an impairment that affects their ability to benefit from a regular education program. Handicapped students require special education because they are often markedly different from most children in one or more of the following ways: mentally retarded ( 发展迟缓的 ), learning-disabled, emotionally disturbed, deal visually handicapped, physically handicapped, or other health impairments. The education of these handicapped children is rewarding but challenging. A special education student usually needs a longer period of time to acquire information. Repetitive teaching techniques are often beneficial, and indefatigable(孜孜不倦的) consistency on the part of the teacher is frequently necessary. Interactive videodisc courseware has characteristics that can be capitalized upon to meet the challenges that special education poses. A videodisc program is infinitely patient. Repetition of any videodisc lesson can continue endlessly, and designers can assure absolute consistency within a program. Most important, according to special educator William Healey of the University of Arizona, is that videodisc "adds an extra dimension of realism for children who need graphic representations". Healey explained that deaf and mentally retarded children especially have difficulty grasping figurative ( 比喻的 ) language and higher-order language concepts. He believes that for special education, the power of videodisc lies in the ability of the technology to visually represent language concepts normally taken for granted by non-handicapped persons. Complex figurative language forms such as idioms and metaphors come most readily to mind as being difficult for handicapped learners. According to Professor Healey, we may infer that mentally retarded children perhaps ______.
