Several years ago, a student working on a research project in my laboratory approached me with concern.“I’m doing something wrong,”she exclaimed. I had seen her research results and knew she was making good progress, so I was surprised to hear that she was having a problem. Over the next several days we went through her experiment; yet I could not find a problem. Finally, I asked her,“Why do you think you’re doing something wrong?” “Because I’m not getting what you said I should get,”she replied with some confusion.

Her response shocked me. I had not told her what she“should get”, but we had discussed some published hypotheses(假说) several weeks earlier. On seeing the research data that did not fit these predictions, I recognized that she had a new finding and came to change my hypotheses. But she was interpreting her results as a mistake. With almost four years of a college science major behind her, this student still had the common misunderstanding that science is a boring exercise in proving something we already know to be true.

But how can this happen? Throughout school, science is often described in textbooks as a series of“known”facts and figures; for example, DNA is a double helix; earthquakes occur at plate boundaries, etc. Unfortunately, the process by which these discoveries were made and how they fit into scientific progress are often ignored in the classroom. These details help show the nature of scientific discoveries and the tails help show the nature of scientific discoveries and the skepticism(质疑) that goes with new discoveries before they are accepted.

Understanding science is more than memorizing that DNA is a double helix. It is to have the ability to take in new information on diet, exercise, or disease and apply it to our own lives. Understanding the process of science and scientific problem-solving can help us make better decisions every day.

Chinese scientists are again becoming excited about the fact that a large hairy animal may live in central China. Now they hope it won't be too long before they are able to __71  its existence. Their confidence is the __72  of a new discovery of the mystery animal in Hubei Province.

Ten Chinese __73  , enjoying a holiday in a National Forest Park, were driving down a road. As their bus turned a corner, the men were suddenly __74   by what they saw. Three __75  animals, covered with long dark hair, were crossing the road. On seeing the animals, the engineers immediately stopped and __76 them. __77  ,when they saw how the animals moved through the forest with great __78  and strength, they did not dare to follow any further.

The men did not take any __79  . However, scientists are __80  by the discovery, because the engineers were all very educated people and scientists feel they can __81   what they described.

After the discovery, scientists returned to the forest and __82   some hair and measured footprints. About 20 inches appears to be the length of the animal's foot! Chinese scientists have now set up a special group to exchange information and make a __83  of the forest. But in the meantime,some people __84 to believe that this half?man, half?monkey exists. They will not believe that it is __85  until one of the animals has been caught.
