【优化方案】2015届高考英语一轮复习 第一部分 基础考点聚焦 Unit5 The power of nature单元检测同步探源 新人教版选修6 Ⅰ.阅读理解(2014·河北普通高中高三教学质量监测)The s Environment Programme is calling for urgent action to reduce growing risks from chemicals.Better management of chemicals could save millions of lives and billions of dollars.As estimated，143，000 chemicals are now produced.Yet the report says only a small number of these chemicals have been studied for their effects on human health and the environment.It says death and disability rates are high from the unsafe use of chemical products. Sylvie Lemmet，director of the United Nations Environment Programme，says poor management of chemicals has a high economic cost.For example，she says the cost is higher than the amount of overseas development aid，or ODA，for health care in sub-Saharan Africa. She says，“If you look at the estimated cost of poisoning from pesticide in sub-Saharan Africa，only the injury and the loss of working time is estimated to be 6.3 billion US dollars in 2009.This is higher than the total ODA that is going to the health sector in the same area.?The United Nations Environment Programme estimates that chemical sales worldwide will increase by around three percent a year until 2050.Chemical production is moving quickly from developed to developing countries.By 2020，chemical production is expected to increase by 40 percent in Africa and the Middle East and 33 percent in Latin America.One of its biggest concerns is pollution of rivers and lakes by pesticide and fertilizer.Other major concerns are heavy metal pollution from the production of cement and textiles，and dioxin pollution from mining. The UN report urges the chemical industry and governments to work together to develop safety policies.It says preventing harm costs less than fixing it. 【文章大意】　本文讲的是联合国环境规划署号召我们要采取行动来减少日益增加的化学产品给人类带来的危害。 of Paragraph 3 is mainly to indicate that ________．C．chemicals have a high production cost D．the estimated cost of poisoning from pesticide is inaccurate 解析：选A。段落
