Chimpanzees and humans are alike in many ways. A baby chimp laughs when its mother tickles it. After chimpanzees fight, they kiss and make up. When one chimp comforts another, it gives it a hug or pat on the back. There are, of course, many ways that chimpanzees and humans are different. Chimpanzees are smaller and stronger than humans. An adult male chimpanzee stands three or four feet tall and weights about 100 pounds. But a chimpanzee can lift more weight than a man who is six feet tall.

Wild chimpanzees are rapidly disappearing. Some people are trying to solve this problem. Otherwise, chimpanzees may one day exist only in zoos. People are trying to save the rain forests and woodlands where the chimps live from being cut down. It will take many people working together to solve this problem

No one knows the true origin of ice-cream, but the first published ice-cream recipe appears in “Mrs. Mary Eales's Receipts,” a cook book that was printed in London in 1718. Sometime around 1832, an African American confectioner named Augustus Jackson created multiple ice cream recipes and invented a superior technique to manufacture ice cream. Ice cream soda was invented around 1874, but the real breakthrough may have been at the 1904 World’s Fair in St. Louis, Missouri, when the American ice-cream cone was unveiled!

Making ice-cream is not easy. Cream and sugar have to first be mixed in a frozen container. Ingredients may be added at this point, if desired. The mixture must be stirred and whipped until the cream and sugar mixture is frozen. Depending on the equipment, this may take as long as an hour. After the ice-cream is prepared, it must be kept frozen until it is ready to be enjoyed. Making ice-cream is difficult, but most people would agree that it is worth the trouble.

After losing a tooth, children in the United States look forward to a visit from the tooth fairy. In Latin America, however, children wait instead for a visit from Ratoncito Pérez (also known as El Ratón Pérez). Instead of a fairy, Ratoncito Pérez is a mouse. Like the tooth fairy, Ratoncito Pérez takes lost teeth that children leave under their pillows. While the tooth fairy usually leaves money, Ratoncito Pérez might leave a small gift.

For hikers who get lost in the woods, a compass can save lives. A compass is a simple tool made of a small case holding a floating needle, or pointer. The pointer has a magnet on the end that points to Earth's northern magnetic pole. Looking at the compass, lost hikers can see which direction is north. Knowing which way is north helps them figure out the other directions and find their way to safety.

Everyone knows that sugar tastes good, and it can give you energy. But scientists say that if you eat too much sugar, then it can damage your body. Too much sugar can make you feel tired. It's bad for many of your organs, including blood vessels and the heart. It can cause weight gain. And, of course, sugar can lead to cavities, or holes in your teeth.

Early spring is sugaring season in the northeastern United States. That's when sugar makers turn the sap of maple trees into syrup. In February, they tap the sugar maples. They drill small holes in the trees' bark. They put a bucket or plastic tube into place to collect the sap. In March or April, the maple trees' sap starts flowing. The sugar makers collect the sap and boil it. The water evaporates, and what's left is pure, delicious maple syrup. When the maple buds come out in May, sugaring ends and the taps are pulled out.

Passengers entering New York Harbor are greeted by a great lady. She is the Statue of Liberty, and she is hard to miss. For one thing, she stands alone on a small island in the middle of the harbor. For another, she's tall, very tall. From the ground to the top, she measures more than three hundred feet. That's as high as a thirty-story building. And she holds, raised high in her right hand, a torch to light the way.

Hudson hurried out of the house so he wasn't late for work. He wore overalls and carried a toolbox with wrenches in it. He hopped in his truck and drove off. The sign on his truck said, “Pipe Masters.” He was happy to fix Mr. Smith sink.

Everett held his father's hand as he crossed the busy parking lot. They walked into a grocery store. Everett's dad lifted him into the seat of the shopping cart. “Here,” said dad, “You can hold my shopping list.”

What is an inference?

Trudy looked down; the sound of everyone’s laughter burned in her ears. She felt her face grow warm and knew she was turning red. She wished she could just walk out of the classroom.
