阅读理解Environmental health is defined as the control of the factors (因素) in the environment that may have harmful effects on people’s physical, mental, or social well-being (安乐). Because natural disasters expose people to danger by bringing up or threatening their immediate environment, effective management of environmental health after a natural disaster is of great importance. The environmental health measures that must be considered after a natural disaster include the supply of appropriate shelter for individuals or groups of people left homeless, the distribution (分配) of safe and accessible water, and the protection and distribution of safe food products and so on.To effectively manage environmental health during and after a disaster, it is important that a state of preparation is in effect before the event actually occurs. During an emergency, success largely depends on making good, rapid judgment and appropriate response measures. High-level decision makers, therefore, must be familiar with sound measures beforehand and should be given an accurate judgment of the disaster’s specific effects as quickly as possible. This book is intended to serve as a guide for those who may be called upon to make emergency decisions after disaster strikes. The remended environmental health measures have been listed in the order of priority in which they should be taken during an emergency. However, each natural disaster is unique in the degree or type of emergency. In response to any given disaster, decision makers may find it necessary to change the priority assigned to any particular measure.1.The first paragraph is mainly to _____.A.tell the reader how to understand environmental healthB.express why environmental health after a natural disaster is importantC.describe the terrible scene that is caused by the natural disastersD.give advice on how to deal with the management of environmental health2.In order to effectively cope with the emergency, the most important is that _____.A.we should have enough shelters and toolsB.everyone should be familiar with the situationC.we should be well prepared for it in advanceD.we can deal with it just as we did before3.We can’t do just as the remended environmental health measures because _____.A.some of the measures have not been taken beforeB.they are not the same according to different degrees or types of emergencyC.they are probably made up by someone without experienceD.they can’t be changed once they are taken by the experts4.The best title of this passage should be _____.A.Environmental Health Management after Natural DisastersB.The Bad Influence of the Natural DisastersC.Useful Measures to Avoid the Natural DisastersD.The Importance of the Environmental Health Management
