阅读下文，回答题Birth, marriage and death:these are the greatest events in human life. Many things, good and bad, can happen to us in our lives. (79)Yet there are three days which are usually marked by some kind of special ceremony: the day we are bom ;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 and death. All human beings-- from the most primitive to the most sophisticated--are affected by these three events. The only thing that differs in each society is the way these events are celebrated. Yet all societies share com- mon characteristics. Birth is a time of joy. The proud parents receive congratulations and presents on behalf of the new-born. Marriage is also a time of joy. The young couple go through a special wedding ceremony and receive presents to help them set up their home. (80)Death is a time of sorrow and is marked by a special ceremony and mourning. The dates of all three events are usually remembered.
