Now the test questions in the college entrance examination accounted for a relatively large proportion, and test questions from operational issues to design problems over .I generalize the students in the experimental design of the four groups of familiar terms, analyzed the hope that candidates Is helpful.A, isotope markers, radioactive markers, fluorescent markers in an open class, our classmates full of activities, the courage to show themselves in such a perfect open class, generated a very meaningful question. At the time of the class activities with a single such a question: Please design a cell membrane to prove the mobility of experiments. A group of students designed such a reality
