Birth, marriage and death, they are the greatest events of human life. ① In our life, many events good
or bad may happen to us. But there are three days which are usually marked by some kinds of special
ceremony (仪式): 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 on the three: we can only choose to or not to marry.
②We have no choice in birth and death. Almost all human beings----______ the most primitive (原始的)
______ the most civilized (文明的)---are affected by these three events. The only thing that differs in each
society is the way these things are celebrated. In fact, all societies (社会) share some common characteristics.
Birth is a joyful event. The proud parents receive congratulations and presents from their relatives and friends
because of the new-born. Marriage is also a delightful event. The young couple (夫妇) go through a special
wedding ceremony; receive presents and set up their new home.
Death causes much sorrow and is marked by a special ceremony and mourning. The dates of all these
three things are usually remembered.
