We now think of chocolate as sweet, but once it was bitter. We think of it as a candy, but once it was a medicine. Today, chocolate can be a hot drink, a frozen dessert, or just a snack. Sometimes it is an ingredient in the main course of a meal. Mexicans make a hot chocolate sauce called mole and pour it over chicken. The Mexicans also eat chocolate with spices like chili peppers.
Chocolate is a product of the tropical cacao tree. The beans taste so bitter that even the monkeys say “Ugh!” and run away. Workers must first dry and then roast the beans. This removes the bitter taste.
The word “chocolate” comes from a Mayan word. The Mayas were an ancient people who once lived in Mexico. They valued the cacao tree. Some used the beans for money, while others crushed them to make a drink.
When the Spaniards came to Mexico in the sixteenth century, they started drinking cacao too. Because the drink was strong and bitter, they thought it was a medicine. No one had the idea of adding sugar. The Spaniards took some beans back to Europe and opened cafes. Wealthy people drank cacao and said it was good for the digestion.
In the 1800s, the owner of a chocolate factory in England discovered that sugar removed the bitter taste of cacao. It quickly became a cheap and popular drink. Soon afterwards, a factory made the first solid block of sweetened chocolate. Later on, another factory mixed milk and chocolate together. People liked the taste of milk chocolate even better.
Besides the chocolate candy bar, one of the most popular American snacks is the chocolate chip cookie. Favorite desserts are chocolate cream pie and of course an ice cream sundae with hot fudge sauce.

Mary Kimble Smith was an ordinary 12-year-old girl; ordinary, that is, in every way    1          one. She suddenly started to walk in her sleep. No one knew why this happened. The best guess seems to be that it represents   2           : the sleep-walker is worried. This feeling normally remains under control during      3              hours, but at night, when the mind is in a more passive mode, it   4              to the surface and shows itself in the form of physical movement.

The Pecan Thief
When I was six years old, I was visiting my grandfather's farm in Kansas. Grandpa had sent me into the   36  to gather pecans for us to enjoy later.
Pecan picking was really   37  work and my little basket was only half full. I wasn't about to   38  Grandpa down. Just then something caught my   39  . A large brown squirrel was a few feet away.  I watched as he picked up a pecan, hurried to a tree and   40  in a large hole in the trunk. A moment later the squirrel   41  out and climbed down to the ground to pick up another nut. Once again, he took the pecan back to his hiding place.
Not so   42  anymore, I thought. I dashed over to the tree and looked into the hole. It was   43  with pecans! Golden pecans were right there for taking. This was my   44 . Handful by handful, I scooped all of those pecans into my basket. Now it was full! I was so   45  of myself. I couldn't wait to show Grandpa all the pecans.   46 , I ran back and shouted, “Look at all the pecans!” He looked into the basket and said, “Well, well, how did you find so many ? ” I told him how I'd   47  the squirrel and taken the pecans from his hiding place.
Grandpa congratulated me on how smart I'd been in observing the squirrel and his habits. Then he did something that   48  me. He handed the basket back to me and put his arm gently   49  my shoulders.
“That squirrel worked very hard to gather his winter   50  of food, ” he said. “Now that all of his pecans are gone, don't you think that little squirrel will   51  the cold winter? ”
“I didn't think about that,” I said.
“I know, ” Grandpa said. “But a good man should never take   52  of someone else's hard work.”
Suddenly I felt a bit   53 . The image of the starving squirrel wouldn't   54  my mind. There was only one thing I could do. I carried the basket back to the tree and poured all the nuts into the hole.
I didn't eat any pecans that night, but I had something much more filling—the   55  of knowing I had done just the right thing.
