　　In the top 10 of unpleasant sounds，a crying baby ranks very high. It instantly makes a key part of your brain called the amygdale(杏仁孔) active，which，among other things，acts as a sort of radar for emotional threats. So why would babies need to cause this sort of urgent reaction？To get you to respond and fast to ensure their survival.

　　Babies can't fend for themselves. They are like chicks in their parents' nest，depending on others to keep them warm，fed and safe. Like chicks，their cries signal driving necessities such as a need for food or protection from danger. But human babies can also convey a range of other needs with cries.

　　Human babies are also highly social，and are interested in engaging in a dialogue with their caregivers. So they are equally attentive to their parents' signals：the messages conveyed by the body language of their caregivers-how the parent smells，touches，holds，rocks，as well as their tone of voice. In relaxed moments with the parent，they soon discover how smiling at an attentive adult tends to cause a positive response in return.

　　On the other hand，these early attempts at communication between the parent and child can be very hit-and-miss. In the first few weeks，most babies cry for about two hours a day. When the parent and baby aren't "getting" each other，crying can increase. In particular，long difficulties with breast-feeding can lead to a pattern of "established firmly" crying behavior.

　　Crying is a signal that can mean many different things. The lessons that are learned from these early experiences are highly significant for individual lives，but collectively they also have a great effect on our culture.
