[15:04.41]4.3 Note-Taking    2 Now listen to the passage,
[15:14.63]and this time complete the chart with the ideas you hear on the tape.
[15:21.03]A punctual person is in the habit of doing something at the proper time
[15:28.13]and is never late in keeping an appointment.
[15:32.73]The unpunctual man,on the other hand,
[15:37.72]does not do what he has to do at the proper time.
[15:43.31]He is always in a hurry and in the end loses both time and his good name.
[15:51.69]There is a proverb which says,"Time flies never to be recalled."
[15:59.19]A lost thing may be found again,but lost time can never be regained.
[16:07.00]Time is more precious than material things.
[16:12.20]In fact,time is life itself,and the unpunctual man
[16:20.09]is forever wasting his most valuable property as well as others'.
[16:26.78]Moreover,failure to be punctual can be extremely harmful
[16:34.17]when it comes to doing one's duty.
[16:38.77]Imagine how it would be if those who are trusted with important tasks
[16:46.08]failed to be at the proper place at the appointed time.
[16:52.27]Therefore,a man who is habitually unpunctual is never trusted by his friends.
[17:00.68]He is often a source of trouble to others and to himself.
