本考题是从美国纽约州高中毕业统考复习用书《生物学简明复习指导》的最后附录部分摘译下来的。它反映当前美国(1980年)生物统考的要求和水平,可用为我国生物学复习的参考资料。美国的试题出得比较灵活,可在较短时间内,较全面地考查学生对知识掌握的程度。当然,我们应该结合自己的实际情况,选择参考。 This exam is extracted from the final appendix of the “Guide to Concise Biology Review”, a high school graduation exam book in New York State, USA. It reflects the current requirements of the United States (1980) biometric examination and the level of reference available for the review of biology in our country. The questions in the United States are more flexible and can be used to examine students’ mastery of knowledge in a relatively short period of time. Of course, we should combine their own actual situation, choose reference.
