Experiments are the basic methods for students to understand the biology. From college entrance examination in recent years, “to test the ability to test-based, based on the knowledge as the carrier ” is one of the principles of the college entrance examination proposition, college entrance examination to strengthen the ability of experimental operation and experimental analysis of the ability to test questions used Basically, knowledge points from the students learned in the high school of the backbone of the basic knowledge and experimental design ideas and analysis methods. The author of the observation and identification of experimental questions breakthrough strategy analysis is as follows.
