One of the most famous scientists to study adaptations(适应,改变)was Charles Darwin. He was born in England in 1809. He wasn' t the best student in his school. When he was 16, his father sent him to a medical school. Charles liked spending time outdoors observing(观察) nature more than attending medical classes. He dropped out without graduating.

Next, Charles' father sent him to school to become a minister (牧帀).This time he made it to graduation, but he didn' t want to do the work of a minister. His friends encouraged him to follow his interest in science.

After graduation, Charles was invited to sail (乘船航行)on the Beagle as an unpaid scientist. He wasn’ t the first choice, but he was the lucky one to go. The Beagle was to travel to South America and then around the world. The crew' s task was to make maps o£ the places they visited.

On December 27th, 1831, Charles Darwin sailed from England on the Beagle. The trip \ was planned to last two years. In fact, it lasted five. During the time, he saw many amazing things. He collected lots of plants and animals and took them back to England to study.

Twenty - three years later, Darwin published a scientific paper with another man named Wallace. Darwin described how some animals have adaptations that help them survive. They are passed on to offspring (后代).

Say you’re sitting around with some friends playing video games and someone mentions a game that happens to be one of your favorites. “Oh, that game’s easy. So not worth the time,” one of your friends says.The others agree. Although you enjoy the game quite a lot, not wanting to argue with them, you go along with the crowd.

You have just experienced what is commonly referred to as peer pressure(同伴压力), also called peer influence. You will adopt a certain type of behavior, dress, or attitude in order to be accepted as part of a group of your “peers”. As a teen, you are likely to have experienced the effect of peer pressure in a number of different areas.

We are all influenced by our peers at any age. For teens, as school and other activities take you away from home, you may spend more time with your friends than with your family. As you become more independent, your peers naturally play a greater role in your life.

According to Dr. Casey from Cornell University, teens are very quick and accurate in making decisions on their own and in situations where they have time to think. However, when they make decisions in the heat of the moment or in social situations, their decisions are often influenced by factors like peers. In a recent study, teen volunteers played a video driving game, either alone or with friends watching. The researchers discovered that the number of risks teens took more than doubled when their friends were watching, compared with when they played alone. This shows that teens may find it more difficult to control risky behavior when their friends are around, or in situations where they are extremely angry. Just as people can influence us to make unwise choices, they can also influence us to make good ones. A teen might join in a volunteer project because his or her friends are doing it, or get good grades because his or her friends think getting good grades is important. In fact, friends often encourage each other to study, or try out for sports.

While we are always influenced by those around us, the decision to act or not is up to us. So when it comes to decision making, the choice is up to you.
