Camps help children, too. For most children, overnight camp is the only time during the year independent. Campers live together in cloth tents or in wood cabins. They eat their meals together in a large dining room. Sometimes, however, the first time at summer camp can be difficult. Children might not like living with other campers. They might not like the food. Or, they might not like to do things like swimming in a cold lake. Some new campers miss their parents very much.
Mental health expert Chris Thurber studied almost 330 boy campers, who were between the ages of eight and sixteen. They were staying at an overnight camp. 83% reported that they wished they were at home at least one day during their time at camp. The American Camping Association suggests that parents prepare children before sending them to camp. They say parents should let children help choose the camp. And they advise parents to discuss what the camp will be like and what campers will need to know. Experts say young children may feel better at camp if they bring a toy from home and if their parents write letters to them often.

听力原文： When couples get married, they usually plan to have children. Sometimes, however, a couple can not have a child of their own. In this case, they may decide to adopt a child. In fact, adoption is very common today. There are about 60 thousand adoptions each year in the United States alone. Some people prefer to adopt infants, others to adopt older children. Some couples adopt children from their own countries, others adopt children from foreign countries. In any case, they all adopt children for the same reason -- they care about children and want to give their adopted child a happy life.
Most adopted children know that they are adopted. Psychologists and child-care experts generally think this is a good idea. However, many adopted children or adoptees have very little information about their biological parents. As a matter of fact, it is often very difficult for adoptees to find out about their birth parents because the birth records of most adoptees are usually .sealed. The information is secret so no one can see it.
Naturally, adopted children have different feelings about their birth parents. Many adoptees want to search for them, but others do not. The decision to search for birth parents is a difficult one to make. Most adoptees have mixed feelings about finding their biological parents. Even though adoptees do not know about their natural parents, they do know that their adoptive parents want them, love them and will care for them.
