The editing sites in transcripts of functional genes of rice

When you do some minor image editing (修正) on your computer screen, you may make some mistakes, so from time to time you’d click undo (撤消).
There are things in life we cannot undo as easily and completely as we would with our computer files. A wrong turn, a hurtful word said to a loved one, a bad move — these we all commit as we walk our life’s journeys, no matter how careful we are in our steps. Once committed, we can no longer undo many of these mistakes, especially because unlike with our computer documents, each thing we do and say has vast impact as they involve not just us — the file that we are working on — but also others, the unopened files and computer programs in our system.
So I guess our life’s mistakes are not like our pencil scrawls (潦草书写) that can be effectively corrected with an eraser, or errors on our computer works that can be undone with an undo button. But there are effective and reliable tools we can use—APOLOGY and FORGIVENESS. Simply click the APOLOGY button when you have commit ted a mistake that has hurt a loved one and the words “I’m Sorry” will flash on the other person’s screen. But, you have to be truly sorry and you must be prepared not to commit the same mistake again for your APOLOGY to work. Sincerity is definitely a necessary part.
When someone clicks the APOLOGY button and the words “I’m sorry” flash on your screen, all you have to do is click back the FORGIVENESS (原谅) button. It means that you have wholeheartedly accepted the other person’s APOLOGY. But not only that. You also have to click it when someone has sent you back the message “It’s okay. Forget about it.”. It means that you are also forgiving yourself for your mistake; that you won’t keep feeling so bad having committed it.
And lastly, don’t forget to keep clicking the SAVE button. Going through the whole process of editing—of doing and undoing, of apologizing and forgiving — is useless if you fail to save the LESSON for future use. Let the saved file be a reminder of the healing process you once went through to make yourself better; for you not to forget the lesson; and for others to access and learn from.
