阅读理解。 Long before they can talk children often use body language to show us how they are feeling. If they hang around their mothers quietly, it is easy to tell that they are nervous. Mothers also know that they can calm the child with a touch on the cheek or a gentle word. It seems that we come into the world with a set of gestures already programmed into us. Everybody, regardless of country, race or religion, can look surprised, smile or cry. It also seems that we can recognize our mothers' voice even before we are born. Even a newborn baby will look in the direction of its mother's voice when she is not in sight. Feeding time also means a time when babies and mothers can get closer. The baby can watch the mother's face at the same time. Babies are also excellent observers of facial (of the face) expressions and learn from mothers' reaction whether something is to be feared or not. This is often why first babies are more timid (胆小的) and less relaxed than their later brothers and sisters. The mother is obviously more worried with her first baby but by the time the second arrives she will have gained confidence. Babies never want to be left out of any activity. Even small babies will cry until they can see what is going on around them. Babies learn to communicate quite early with gestures. They point to things and get rewarded when those things are given to them. They laugh during a game and are rewarded when the game is continued. They smile at strangers and are rewarded by being picked up and held in their arms. So learning the body language of the children is as important and rewarding as studying that of another culture. 1.
