首先要把Abstract读明白，这是一篇文章论文的精华，可以对论文的的总体思路进行把握，然后，实验部分略微一看，不用很细，重点看结果与讨论，那是这篇论文你看完后应该得到的东西，另外，如果你已这个领域还不是很熟悉，先找一篇中文文献了解一下专业名字和大致研究状况。
Biological diversity means the variety of living within a certain range of organisms regularly posed by combining the ecological complexes of Including such diverse animals, plants, micro-organisms of the species diversity, species diversity and variation of genetic and ecosystem Among them, the species diversity is the key to biological diversity, it reflects the biological and the environment between the complex relationship between, but also reflects the richness of biological We now know that there are about two million kinds of organisms, these kinds of biological species constitute the diversity of biological Biological diversity is the formation of organisms and their ecology and the environment as well as the complex range of ecological processes related to the sum of genetic diversity, species diversity and ecosystem diversity Genetic diversity refers to the body decided to biological traits and combinations of genetic Species diversity is the diversity of species on biological manifestations can be divided into regional species diversity and species diversity of Ecosystem diversity refers to the biosphere habitats, communities and ecological processes of biological Genetic diversity and species diversity is the basis of the study of biological diversity, ecosystem diversity is the focus of the study of biological Was asked, based on the study of nature can be inferred What are the characteristics of the work of the Creator, is said to British scientists Sanderson Haldane John Leighton replied: "too much like " Because the beetle is the largest animal on Earth Telloy the United States the text of the Smithsonian Institution concluded that the majority of unknown types of beetles may not be able to survive in our near 30-meter-high canopy of tropical
