John, a famous musician, took his priceless old guitar and played it in the crowded subway station. The music was wonderfully streaming throughout the whole      . However, during the one-hour play, only six or seven people were truly      the charming music. A three-year-old kid was fully       in the music that he forget everything around. John       got 52 U.S. dollars for his work that day.
However, in       days, when John is about to hold a      , one ticket can be sold at more than 100 dollars and it is very          to buy a ticket even at such a high price. Therefore, later, many       in the station that day felt deeply regretful for not        the famous musician and missing such a valuable but       music feast.
I have a rich friend whose wife had a       illness. Nevertheless, his wife did not manage to conquer the illness and       soon. He often sighed miserably that due to his past        life, he had missed a lot of beautiful time with his wife. But now, it is impossible to       it.
It is no       crying over spilt milk. We have missed a lot of precious things in our life      knowing to value them. Actually, I also missed something precious before. The        why we would have missed those precious things is less than simple: we had       that we could still own them tomorrow. Nevertheless, tomorrow is       by no means reliable. The result is that they were always too late to cherish (珍惜) what they had before they       it. However, when we reach the condition we have expected, we could no longer realize our wish any more, because we have lost it by then.
