說明：
在課文初步處理時采用jig-saw reading這一方法，可以化整篇閱讀為段落閱讀，使學生通過對所讀課文內容的互動交流，完成不同的練習，實現從部分到整體，逐步熟悉掌握課文的目的。在活動的各階段，教師可設計不同的任務，有針對性地訓練學生的閱讀能力。整個活動都是以小組為單位進行的，這就要求學生通過組員間的配合，來完成任務，培養學生互幫互助的團隊合作精神。

environmental factors play a central role in human development, health, and disease. broadly defined, the environment, including infectious agents, is one of three primary factors that affect human health. the other two are genetic factors and personal behavior.
human exposures to hazardous agents in the air, water, soil, and food and to physical hazards in the environment are major contributors to illness, disability, and death worldwide. furthermore, deterioration of environmental conditions in many parts of the world slows sustainable development. poor environmental quality is estimated to be directly responsible for approximately 25 percent of all preventable ill health in the world, with diarrheal diseases and respiratory infections heading the list.[4] ill health resulting from poor environmental quality varies considerably among countries. poor environmental quality has its greatest impact on people whose health status already may be at risk.
because the effect of the environment on human health is so great, protecting the environment has been a mainstay of public health practice since 1878.[5] national, tribal, state, and local efforts to ensure clean air and safe supplies of food and water, to manage sewage and municipal wastes, and to control or eliminate vector-borne illnesses have contributed significantly to improvements in public health in the united states. however, the public’s awareness of the environment’s role in health is more recent. publication of rachel carson’s silent spring in the early 1960s, followed by the well-publicized poor health of residents of love canal in western new york, a significant toxic waste site, awakened public consciousness to environmental issues. the result of these and other similar events is the so-called environmental movement that has led to the introduction into everyday life of such terms as superfund sites, water quality, clean air, ozone, urban sprawl, and agricultural runoff.
