Birth, marriage and death: these are the greatest events in human life. Many things, good

and bad, can happen to us in our lives. Yet there are three days which are usually marked by some kind of special ceremony: the day we are born, the day we get married and the day we die. These are the three main events in life. We only have a choice in the second of these: we can choose whether or not to marry. But we have no choice in birth or death. All human beings-from the most primitive to the most sophisticated -are affected by these three events. The only thing differs in each society is the way these events are celebrated. Yet all societies share common characteristics. Birth is a time of joy. The proud parents receive congratulations and presents on be- half of the new-born. Marriage is also a time of joy. The young couple go through a special wed- ding ceremony and receive presents to help them set up their home. Death is a time of sorrow and is marked by a special ceremony and mourning. The date of all three events are usually remembered.

______ is the only thing we can choose in these three events.

A．How to celebrate the special days

B．Whether or not to marry

C．When to die

D．The day a new life born
