根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项

When you are waiting in front of a theater or at the train terminals, you will realize how important punctuality is. Punctuality is really a virtue, especially in a busy city.     小题1:      .

Punctuality is the main constituent(构成部分)of good character.  小题2:  On the other hand, a person who is always late shows his selfishness and thoughtlessness and he is not worthy to be friends with.

Some people often say that they cannot always be punctual since traffic is so heavy these days.   小题3:    As everybody knows, we might meet an unexpected jam on the roads, so we should leave a bit earlier for the appointment to ensure that we would not be late.

  小题4:  . When they finally arrive, they keep on saying sorry to their friends and then explain. The excuse is not always traffic jam. Sometimes they complain that they have met a friend on the road or have helped a blind man to cross the road. Some also like to blame their watches, the clocks at home or in the office. To such people, we cannot help but say sorry that we have come too early.

Yet after all, such smart fellows will soon find that gradually their friends become fewer and fewer. Perhaps at that time, they would realize how important punctuality is.

  小题5:  . So when we are young, we should try to be punctual every time and never be late, for it is much more easily acquired in youth than when we are older.

A.To be or not to be punctual is a habit.
