Passage One
A guide dog is a dog especially trained to guide a blind person. Dogs chosen for such training must show good intelligence, physical fitness, and responsibility.
At the age of about fourteen months, a guide dog begins an intensive course that lasts from three to five months. It becomes accustomed to the leather harness and stiff leather handle it will wear when guiding its blind owner. The dog learns to watch traffic and to cross streets safely. It also learns to obey any command that might lead its owner into danger.
The most important part of the training course is a four-week program in which the guide dog and its future owner learn to work together. However, many blind people are unsuited by personality to work dogs. Only about a tenth of the blind find a guide dog useful.

Passage Two
People dream four to six times a night. They dream while they are in the REM stage of sleep, which means rapid eye movement stage in one’s sleep. Sleepers go into the REM stage about every 90 minutes. The first dream of the night may last about ten minutes. Each dream gets a little longer. The last dream of the night may be an hour long.
People need their dreams. Younger children spend more time dreaming. Babies spend almost half of their sleep in the REM stage.
One experiment showed that everyone needs to dream. Doctors gave some people sleeping pills. These sleeping pills didn’t let them go to REM sleep. After a few nights without dreams, they began to feel bad. They became angry easily, they worried a lot, and they wanted to fight with everyone. Then they stopped taking the sleeping pills. They all began to dream all night for a few nights to catch up.
Why do people dream? Dreams give them time to find the answers to some of their problems. If they think they will have difficult problems the next day, they may spend more time on REM sleep the night before. In their dreams, they may find an answer to their problems.
