B

Eric liked to save pennies． He saved pennies from jobs for his mother, and gifts from relatives．Whenever his grandfather came to visit, he told Eric that he could have all the pennies in his pocket． Grandpa always had quite a few.

He filled a small box with pennies． Then he put some into an empty bottle． The bottle was soon full of pennies, so he started another one.

When his uncle came to visit, Uncle Alan said, “What are you going to do with all those pennies, Eric? A penny doesn't buy much these days．Maybe you should start a collection.”

Uncle Alan took him to a store, and they bought two books． One book had little spaces for pennies made in different years． The other one told how much money a coin dealer would pay for rare pennies． Eric was amazed that a penny sometimes was worth much more than one cent．

“Let's look through your pennies and see what you have here, ” Uncle Alan said.

They looked at the dates on the pennies and sorted them into piles by the years in which the pennies were made． Eric then chose the best one from each year to put into his collection book． He soon filled up most of the spaces with pennies．

One penny, however, was different． It was one Eric had found in his own backyard under a big bush． It had been there for a long, long time． He checked the date on the penny, and then looked into the book that told the value of pennies．

“Thirty dollars,” the book said ! Not many pennies had been made that year, so each one was rare.

“Well, what are you going to do, Eric?” his uncle asked:“Are you going to sell it so that you can have a lot of money? ”

Eric thought of all the things he could buy with that much money．Then he said, “No, I would rather keep the penny as my own.”

54．What did Eric decide to do with the valuable penny he found? A． He sold it for thirty dollars．B． He kept it so he could enjoy owning something so rare．C． He bought his family a treat at the store．D． He gave it to his grandpa for helping him save pennies．55． Grandpa always had quite a few pennies in his pockets when

he came to visit Eric's family because ______．A． he knew his grandson liked pennies B． he was a rich man, so he could give money away C． pennies do not buy much these days D． he wanted to play a trick on Eric so that he could make fun of

him

56．What will probably happen in the future if Eric's special penny is worth thirty dollars now ?

A． The value will increase because collectors will want it more when it is older.

B． People will not want it in the future, so the value will go down．C． Eric will not take very good care of it and will probably lose it．D． Grandpa will give it to one of his other grandsons．57． A penny that is rare would be of greater value than one from a

year in which many pennies are easy to get because A． collectors want to fill their books B． the value of pennies always rises C． there are not enough pennies for everyone who wants to own one D． people want to have something that belongs to someone else

CGo and watch the baby when he is asleep． See how his chest rises

and falls, then rises and falls again．He does not know what he is doing, but he breathes as perfectly as the

oldest and the wisest man in the world． He began to breathe when he was born, and he will not stop until he dies, still he does it without thinking about it．

See how long you can hold your breath and be comfortable．

In some places men dive in the ocean for pearls (珍珠 )． They pick up shells (贝壳 ) that hold the pearls, and the longer they stay underwater the more pearls they can find． For this reason they hold their breath as long as they possibly can． Yet even these pearl divers cannot go without breathing for a long time．

Watch to see how many times a man draws his breath every minute． Some men breathe fifteen times a minute: An elephant breathes only eight times． It was said that a mouse breathes a hundred and twenty times each minute．

No one needs to tell us that what we breathe every minute of every day is air． It is around us everywhere, like wonderful ocean that we cannot see．It also stretches far above us and above the clouds． fifteen times a minute: An elephant breathes only eight times． It was said that a mouse breathes a hundred and twenty times each minute．

No one needs to tell us that what we breathe every minute of every day is air． It is around us everywhere, like wonderful ocean that we cannot see．It also stretches far above us and above the clouds.

58． Pearl divers are men who dive in ocean ______.A． to pick up shells B． to pick up fish C． for pearls D． to pick pearls
