     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 committed 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.

1. Which of the following is TRUE?

A. However careful we are, we still make mistakes in life.
B. Things we do and say can affect computer programs in our system.
C. We can undo life's mistakes if we are careful enough.
D. An eraser is an effective tool for our computer works.

2. The APOLOGY button should be clicked when ________.

A. one wants to make the computer work perfectly
B. one's mistakes won't influence others any more
C. one is actually saying "I'm sorry"
D. one won't make the same mistake again

3. What does the underlined word "it" in Paragraph 4 refer to?

A. The UNDO button.
B. The APOLOGY button.
C. The SAVE button.
D. The FORGIVENESS button.

4. We need to click the SAVE button in life because ________.

A. we want to go through the whole process of editing
B. we need to learn a lesson from the past mistakes
C. we want to make the healing process faster
D. we need to use the computer properly

How Long Can People Live?

  She took up skating at age 85, made her first movie appearance at age 114, and held a concert in the neighborhood on her 121st birthday.

  Whe n it comes to long life, Jeanne Calment is the world’s recordholder.She lived to the ripe old age of 122.So is 122 the upper limit to the human life span(寿命)?If scientists come up with some sort of pill or diet that would slow aging, could we possibly make it to 150-or beyond?

  Researchers don’t entirely agree on the answers.“Calment lived to 122, so it wouldn’t surprise me if someone alive today reaches 130 or 135,”says Jerry Shay at the University of Texas.

  Steve Austad at the University of Texas agrees.“People can live much longer than we think,”he says.“Experts used to say that humans couldn’t live past 110.When Calment blew past that age, they raised the number to 120.So why can’t we go higher?”

  The trouble with guessing how old people can live to be is that it’s all just guessing.“Anyone can make up a number,”says Rich Miller at the University of Michigan.“Usually the scientist who picks the highest number gets his name in Time magazine.”

  Won’t new anti-aging techniques keep us alive for centuries?Any cure, says Miller, for aging would probably keep most of us kicking until about 120.Researchers are working on treatments that lengthen the life span of mice by 50 percent at most.So, if the average human life span is about 80 years, says Miller,“adding another 50 percent would get you to 120.”

  So what can we conclude from this little disagreement among the researchers?That life span is flexible(有弹性的),but there is a limit, says George Martin of the University of Washington.“We can get flies to live 50 percent longer,”he says.“But a fly’s never going to live 150 years.”

  “Of course, if you became a new species(物种),one that ages at a slower speed, that would be a different story,”he adds.

  Does Martin really believe that humans could evolve(进化)their way to longer life?“It’s pretty cool to think about it,”he says with a smile.
