In Canada you can find dogs， cats， horses， etc. in almost every family. These are their pets. People love these pets and have them as their good friends. Before they keep them in their houses， they take them to animal hospitals to give them injections(注射) so that they won't carry disease. They have special animal food stores， though they can get animal food in almost every kind of store. Some people spend around two hundred Canadian dollars a month on animal food. When you visit people's houses， they would be very glad to show you their pets and they are very proud of them. You will also find that almost every family has a bird feeder in their garden. All kinds of birds are welcomed to come and have a good meal. They are free to come and go and nobody is allowed to kill any animal in Canada. They have a law against killing wild animals.

Language is always changing. In a society where life continues year after year with few changes, the language does not change either. The earliest known languages had difficult grammar but a small, limited vocabulary. Over the century, the grammar changed, and the vocabulary grew. For example, the English and Spanish people who came to America during the sixteenth century gave names to all the new plants and animals they found. In this way, hundreds of new words were introduced into English and Spanish vocabularies. Today life is changing very fast, and language is changing fast too.

There are several major(主要) language families in the world. Some scientists say there are nine main families, but other scientists divide them differently. The languages in each family are connected, and scientists think that they came from the same parent language. About 3 percent of the people in the world speak languages that are not in these major families.

A. a lot of problems B. words and easy grammar
