Article: To "sacrifice" means to give up something for the sake of something else. We decided to sacrifice our luxurious city life to move to a seaside village with our children aged 9 and 3. In the city, we had a beautiful home and plenty of money but little real security because crime was on the increase every day. We never knew if we would all make it home safely each night. We were very happy in the new town but life was very difficult economically. Our income was very much dependent on tourism and the jobs at other times are few. Although many of the long-standing residents live well, it is a very competitive environment for newcomers. Reading the newspapers from the big cities assured us that we had made the right choice. There is so much violence and crime there! However, it was not always easy to explain .to the children why they could no longer have what they used to have, especially when our "rich" friends came from the city to visit. One day, one of our "rich" friends came to visit us. His son preferred riding in the back of our _ truck to his father's modern car. Our little daughter called me and said, "Mom, please help me explain to James why he is wrong. He said, 'today, if you don't have money you are nothing.' I know that is not true. If you do have money you share it with your friends and if they don't have money, you share it with them. That is what makes us all rich." This made me realize that the sacrifice was well worth it. Our kids have a solid set of values and they know that our most precious gifts are our good friends and a wonderful environment.
Answer: The city was not safe enough.

Why did the family move away from the city?

Article: What do you know about the sea? You may have seen it. Some of us have swum or bathed in it. It looks beautiful on a fine sunny day and it can be very _ when there is a strong wind. What other things do we know about it? Of course, the sea is very large. In the world there is more sea than land. The sea covers three quarters of the earth. The sea is also very deep in some places. It is not deep everywhere, some parts of it are very great. At one spot, near Japan the sea is nearly 11 kilometers deep! Just think of it, the highest mountain in the world is only about 9 kilometers high! If you have swum in the sea, you know that the water is salty. Rivers carry salt from the land into the sea. Some parts of the sea are more salty than other parts. Do you know the Dead Sea in Arabia? It is very salty. Swimmers cannot sink in it! Fish cannot live in the Dead Sea. It is a strange sea. In most parts of the sea, there are a lot of fishes and plants. Some live near the top of the sea. Others live deep down. No sunlight can reach the depth of the sea. So it is completely dark. Strange fishes live there. Some are blind. Some have their own lights. Some have great jaws. With their great jaws, they swallow fish larger than themselves. The sea can be very cold. Deep sea divers know this well. At the top of the water may be warm. Then as the divers go down, the sea becomes colder and colder. Many scientists are now making a study of animal and plant life in the sea. They hope to find new resources for mankind.
Answer: The salt in the sea mainly comes from the land.
