Jennifer considers me like a friend to talk, laugh, and do things with her. She believes that I am a friend she can depend in time of need. I was watering the flowers in the garden this morning when she drops in, telling me that she needed my help because I was in low spirits. When asking what made her so unhappy, Jennifer told me her friend Tina was reading her diary the other days when she entered the classroom. She was too angry at the time that she shouted at her, which, of course, ended their friend. Having heard what she said, I said, "We shall never have friends unless we expect to find them without faults."

Years ago, a Southern woman was in one of my workshops. When asked to tell a story that  36 her character (品质), she described an  37 when she was 5. She was at her grandfather’s house  38 up in a beautiful white skirt and new gloves ,   39 as she could be.
Her grandfather told her she could go into the  40 and get herself a cookie. Next to the cookies was a pile of coins. Sure that no one was  41 , she took one of the coins, too.
When she 42 with her cookie, her grandfather asked her to show him her  43 . She held out only her left hand  44 , and he said, “Show me the other hand.” When she unwillingly did  45 , showing the coin, she saw  46 in her grandfather’s eyes.
He paused a moment and then 47 her up, saying, “Darling, you can have anything in the world that I have, but it breaks my heart that you’d ever  48 it.” Some 50 years later, this story of how her grandfather gave her the gift of  49 still brought tears to her eyes.
Few things have as large an influence on  50 the values of a child as the strong pain of lovingly administered shame (羞愧). It helps judge right from wrong and gives a   51 emotional (感情的) dimension to moral (道德的) and character issues.
Kids, and adults for that matter, learn from their  52 . Parents, teachers and coworkers can remind them of their moral responsibilities without shaming or  53 them.
What we can’t do is just let  54 go, unless we want to send the message that’s okay. What we allow, we  55 . And we should never encourage anything other than moral excellence.

                                The Touchstone

    When the great library of Alexandria burned, the story goes, one book was saved. But it was not a valuable book, and so a poor man, who could read little, bought it for very little money.

The book wasn’t very interesting, but between its pages there was something very interesting indeed. It was a thin strip of vellum on which was written the secret of the “Touchstone”! The touchstone was a small pebble that could turn any common metal into pure gold.

The writing explained that it was lying among thousands and thousands of other pebbles that looked exactly like it. But the secret was this: The real stone would feel warm, while ordinary pebbles are cold.

So the man sold his few belongings, bought some simple supplies, camped on the seashore, and began testing pebbles. He knew that if he picked up ordinary pebbles and threw them down again because they were cold, he might pick up the same pebble hundreds of times. So, when he felt one that was cold, he threw it into the sea. He spent a whole day doing this but none of them was the touchstone. Yet he went on and on this way. Pick up a pebble. Cold, throw it into the sea. Pick up another. Throw it into the sea. Pick up another. Throw it into the sea. The days continued over a long period of time.

One day, however, about mid-afternoon, he picked up a pebble and it was warm. He threw it into the sea before he realized what he had done. He had formed such a strong habit of throwing each pebble into the sea that when the one he wanted came along he still threw it away.

    So it is with opportunity. Unless we are careful, it’s easy to fail to recognize an opportunity when it is in hand and it’s just as easy to throw it away.

The man bought the book because ______.

  A. he wanted to read it                   B. it was very interesting

C. there was a secret in the book            D. he wanted to find the touchstone

We can learn from the passage that the touchstone is ______.

A. pure              B. cold               C. magic              D. big

What does the author want to tell us in the passage?

A. We should offer opportunities in our life.

B. We should seek for opportunities in the world.

C. We may seize opportunities when we are watchful.

D. We may discover opportunities when forming habits.
