But speech has to be induced, and this depends on interaction between the mother and the child, where the mother recognizes the signals in the child’s babbling, grasping and smiling, and responds to them. Insensitivity of the mother to these signals dulls the interaction because the child gets discouraged and sends out only the obvious signals,. Sensitivity to the child’s non – verbal signals is essential to the growth and development of language.

　　Hong Kong, major commercial center for Asia, and with a population which has grown at an alarming rate to over 5 million, is a city highly dependent on mass transit of all sorts, both local and long distance. The average Hong Kong worker or businessman, going about his daily activities, simply must use public transportation at one time or another.

　　Because Hong Kong is in two parts, Kowloon, on the mainland side, and Hong Kong, the island, with Hong Kong’s harbor in between, Hong Kong’s mass transit systems, in addition to going over land must also cross water.

　　Going from home to work, or going shopping from one side of the harbor to the other, the Hong Kong resident has three choices. One way is to take a bus, which will cross the harbor through an underwater traffic tunnel moving slowly through bumper-to-bumper traffic. Another way is by ferryboat, a pleasant ride which crosses the harbor in from seven to fifteen minutes.

　　But by far the fastest way of crossing the harbor is the newly built underground electric railway, the Hong Kong Metro. If one boards the train in the Central District, the commercial area of Hong Kong on the island side, he can speed across the harbor in an astonishing three minutes. On the other side of the harbor the railway continues, snaking back and forth through the outlying districts of Kowloon, allowing one to get off a short distance from his destination.

　　The story of the Metro is an encouraging one for supporters of mass transit. Although building the system was certainly a challenging task, the Japanese firm hired to construct it did so in record time. Construction got underway in 1979 and it was completed in 1980.

　　For the average commuter the system has only one disadvantages: it is more expensive than by bus or ferry. One can ride the bus across the harbor for half as much, or he can ride the ferry across for less than one-fifth as much.

　　1.Hong Kong ___.

　　A.can do without mass transit.

　　B.finds public transportation too expensive.

　　C.needs public transportation.

　　D.has an insufficient mass transit system.

　　2.Hong Kong Public transportation extends ___.

　　A.over hills and valleys.

　　B.across land and water.

　　C.through mountains.

　　D.throughout the Kowloon area.

　　3.The traffic in the underwater traffic tunnel is ___.

　　A.heavy

　　B.light

　　C.fast

　　D.dangerous

　　4.Crossing the harbor by train is ___.

　　A.by far the most economical method.

　　B.the most pleasant method.

　　C.the least pleasant method.

　　D.the fastest method.

　　5.The business area on the island side of Hong Kong is referred to be as ___.

　　A.Kowloon

　　B.the Central District
