More than half the people in the world cannot read or write. They can learn about things only by watching and listening. However, people who can read are able to learn about anything they wish.People can read a language better if they have listened to it or learned to speak it. Reading, listening, and speaking are ways people come to understand the words of a language. Being able to write also makes reading easier.A mother or father is often a child’s first reading teacher. By speaking to a baby, the parent helps the baby understand what language is and what it is for. Children feel love and joy in the sounds of words. They try to talk back. As babies listen and speak, they store up facts and ideas. Certain things children do in the early years help them learn. Young children enjoy looking at picture books. Later, the parent reads books that the child can look at as well as listen to. At age five many children are beginning to read and write. Some can recognize their own names. Children continue to learn to read in school with their teacher’s help. Sometimes children read out loud. At other times they read silently. They learn to understand and remember.

Sometimes when you walk outside, you see a little hole with sand around it. Guess what! You have found a city under the ground. Ants live in this city. There, many ants live together with their queen. The queen is the biggest ant of all. Most of the time, there is only one queen in an ant city.When a queen starts her own city, she digs a hole. She takes bits of sand to the top. Then she piles up the sand. It makes a little hill. She is making a good place for her eggs. It is a nest. When baby ants come out of the eggs, they are called grubs. They look like worms. The queen feeds them food and water. But when a grub is a week or two old, it stops eating. It no longerneeds food. It makes a bag around itself and goes to sleep. Then it grows into a big ant.Most grubs turn into worker ants. Workers take over running the nest. They dig more holes. This makes the nest bigger. They also keep it clean. They get food and water. Workers bring food to other ants that are too busy to go out. Some also fight off ants from other cities.Ants are fun to watch.

The first animals to have teeth were fish. These sea creatures lived millions of years ago. They had many finely pointed teeth for grabbing food from the water. They were distant cousins of today’s sharks.The teeth of animals help them do certain jobs or eat certain kinds of foods. Elephants have two large teeth, called tusks, which they use for digging up plants or for fighting. Lions and tigers have long, sharp teeth for tearing apart other animals. Those of horses and cows are short and flat. They are used for grinding plants.People have three main kinds of teeth. They have teeth that cut, teeth that tear, and teeth that grind. When biting into a piece of fruit, people use their cutting teeth. When pulling a piece of meat from a bone, they use their tearing teeth. When nibbling on a fresh carrot, they use their grinding teeth.Every person grows two sets of teeth. The first set often begins to appear when a baby is about six months old. It lasts until the child is about six years old. Then the baby teeth fall out and the second te eth come in. This second set must last for the rest of a person’s life.It is important for people to take care of their teeth. They must eat the right foods. They shouldbrush their teeth properly.

There are even some books for babies. And they can’t even read!People who write for youths write all kinds of books. Some write about real things, like stars, cars, or boats. But others tell stories that are made up. Many of these stories took place in the past. But some show what it’s like to live today. These may be about going to school or being part of a family.Books for young children use a lot of beautiful pictures. They are a big part of each book. So, many writers of children’s books also draw the pictures. These writers make sure that their books are more than just fun stories to read.
