Q: Two English translators.

1. When white people came to this country, Indians had lived here for many years. A large group of them live together and are called tribes. Every tribe has a leader or chief. People live very close, and there are many things.

Indians on the northwest coast catch freshwater or saltwater fish to eat. They use many kinds of boats.

California Indians eat fish, collect seeds and grow tobacco. They use rafts made of logs as water tools.

Indians in the southwest are quiet farming people. They learn to weave beautiful baskets, make pottery and weave cotton cloth very skillfully.

Indians in the eastern lumberyard live by hunting. Some people moved to the prairie and became hunters and soldiers. Grassland Indians live in big tents and follow the pace of bison.

Careful and careless are as different as fire and water. But strangely, many scientists have both, that is, they are both careful and careless. Newton, a famous British scientist, is such an example.

Newton once invited a friend to dinner at home. When they were ready to eat, Newton went to get a bottle of wine. But his friends waited for him for a long time and didn't see him come. Finally, his friends found him in Newton's laboratory. Because Newton suddenly thought of a new idea about the experiment he was doing when he went to get the wine, he completely forgot his friends and dinner.

There's another one. Newton took the reins and the horse for a walk on the mountain. As he walked, he thought about the problems he encountered in his research. When he reached the top of the mountain, he found that the horse had no reins.

Many scientists are careless about their lives because they are too careful in their research.
