DNA is the whole “map” of the human body. It is something that all human have, and it tells the body what to do. DNA is the reason that we look like our parents, because we get some of their DNA to make our own.
People have been trying to understand the human body for a long time. In 1860, Mr. Mendel discovered why we look the same as other people in our family. It is because of small things called “genes”(基因) in our body. In 1953, two scientists, Watson and Crick, found out that those small parts are really messages. They’re written in the DNA with a special language.
In 1961, another two scientists found the first “word” that they could understand in that language. It shows how DNA tells the cell(细胞) to build its parts. So far, scientists have found all the words in the DNA map, but we still do not understand what they all do. By understanding what just one “word” means, we can help to save people from several illnesses. So the more we understand, the more doctors will be able to do.
Most people hope that this will help to make better medicine and help sick people. Other people worry that when we learn more “words” and and find out more information, we will use it in the wrong way, just to make people more attractive, or stop sick people getting jobs.

One day a man found a cocoon(茧)of a butterfly in the forest. He sat there for several hours and watched the butterfly. Suddenly a small opening appeared, and the butterfly made its great effort to force its body through that little hole. Then it seemed to stop making any progress. It appeared as if it had gotten as far as it could and it could go no further.
So the man decided to help the butterfly. He cut off the remaining bit of the cocoon so that the butterfly could come out easily. But to his surprise, the butterfly got a heavy body and very small wings when it came out of the cocoon.
The man continued to watch the butterfly because he expected that the body would grow smaller at any moment and the wings would become larger and be able to fly. But neither happened! In fact, the butterfly spent the rest of its life crawling(爬) around with a heavy body and small wings. It was never able to fly.
The man was in his kindness, but he did not understand the nature rules. Before the butterfly came out of the cocoon, fluid (流体) from its body must be forced into its wings, and then it would be ready for flying. It must have a hard struggle(拼搏)to get through the small opening to get its freedom from the cocoon.
Sometimes struggles are exactly what we need in our life. If God allowed us to go through our life without any difficulties, it would make us fail. We would not be as strong as we could have been; we could never fly.

For many years , Hawaii has been a magic name to people who like to travel. People on both sides of the Pacific Ocean, in Japan and in America, dream of seeing these beautiful islands in the middle of ocean. Their dreams always include at least on scene of a sunset over the ocean. In the tropical （热带的）lands, the sun drops like a ball of golden fire into the sea. And it drops so quickly that you can almost see it move. The sun leaves behind a glow that lights the skies in the quiet water.
People often have a quiet, peaceful time—perfect for a leisurely walk along the water. This scene is not too different from the dramatic beauty that greeted the first strangers to these islands centuries ago. They were Polynesia people who came from Tahiti in canoes that much bigger than small boats.
They found the beautiful white sand beaches and the waving palm trees, but there were no grand hotels like the ones we see nowadays. The first people came to Hawaii nearly two thousand years ago, but skyscraper hotels were only built in the last 30 years. Now jet airplanes make it possible to fly to Hawaii for a weekend from Tokyo or San Francisco or Los Angeles.
Wherever people come from, they really want to see the original（原始的，最初的） beauty of Hawaii. They want to see the lovely beaches and the mountains called Diamond Head which is almost hidden by the tall hotels.

The motivation to succeed comes from the burning desire to achieve a purpose. Napoleon Hill wrote, “whatever the mind of man can conceive (设想) and believe, the mind can achieve.”
A young man asked Socrates （苏格拉底） the secrets to success. Socrates told the young man to meet him near the river the next morning. When they meet, Socrates asked the young man to walk with him towards the river. When the water got up to their necks, Socrates took the young man by surprise and pressed him into the water. The boy struggled（挣扎） to get out but Socrates was strong and kept him there until the boy stared turning blue. Socrates pulled his head out of the water and the first thing the young man did was to gasp（大口喘气） and take a deep breath of air. Socrates asked, “What did you want the most when you were there?” the boy replied. “Air.” Socrates said,“ That is the secret to success. When you want success as badly as you wanted the air, then you will get it. There is no other secret.”
