The destruction of our natural resources and contamination of our food supply continue to occur, largely because of the extreme difficulty in affixing （把……固定）legal responsibility on those who continue to treat our environment with reckless abandon （放任）. Attempts to prevent pollution by legislation, economic incentives and friendly persuasion have been met by lawsuits, personal and industrial denial and long delays—not only in accepting responsibility, but more importantly, in doing something about it.

It seems that only when government decides it can afford tax incentives or production sacrifices is there any initiative for change. Where is industry's and our recognition that protecting mankind's great treasure is the single most important responsibility? If ever there will be time for environmental health professionals to come to the frontlines and provide leadership to solve environmental problems, that time is now.

We are being asked, and, in fact, the public is demanding that we take positive action. It is our responsibility as professionals in environmental health to make the difference. Yes, the ecologists, the environmental activists and the conservationists serve to communicate, stimulate thinking and promote behavioral change. However, it is those of us who are paid to make the decisions to develop, improve and enforce environmental standards, I submit, who must lead the charge.

We must recognize that environmental health issues do not stop at city limits, county lines, state or even federal boundaries. We can no longer afford to be tunnel-visioned in our approach. We must visualize issues from every perspective to make the objective decisions. We must express our views clearly to prevent media distortion and public confusion.

I believe we have a three-part mission for the present. First, we must continue to press for improvements in the quality of life that people can make for themselves. Second, we must investigate and understand the link between environment and health. Third, we must be able to communicate technical information in a form that citizens can understand. If we can accomplish these three goals in this decade, maybe we can finally slop environmental degradation, and not merely hold it back. We will then be able to spend pollution dollars truly on prevention rather than on bandages.

1.【答案】B。

【解析】A、D两项在文章都找不到与此相同的内容，C项与第二段最后一句话矛盾。根据第二段第一句话可知B项正确。

2.【答案】B。

【解析】根据第三、第四段，尤其是第三段第三句、第四段最后一句可知B项正确。有人误选C项，大约是将第三段第一句话的positive（积极的，建设性的）理解为radical（极端的，激进的）。

3.【答案】D。

【解析】根据构词法可知D项正确：tunnel意为“坑道，隧道”。vision意为“视力，洞察力；观察法”。故而不难推测tunnel-visioned是“一孔之见”之类的意思。根据上下文，尤其是第四段第三句话，也可得知be tunnel-visioned意思和visualize issues from every perspective（全面地观察问题）相反。A项意为“心胸狭窄”，B项表示“视而不见”，C项意为“目光短浅”，D项表示“只看到问题的一个方面”。

4.【答案】C。

【解析】根据文章第三段，尤其是该段最后中一句可知答案为C。该段第二句话说，It is our responsibility as professionals in environmental health to make the difference（作为环境与健康方面的专业人员，做得与众不同是我们的责任）。最后一句话说，it is those of us who must lead the charge（我们中的一些人必须承担起领头的责任）。其中those of us后面有一个定语从句，不难看出those of us即environmental health professionals.

5.【答案】A。

【解析】根据最后一句话可知A项正确。该段第四句指出应向人们提供technical information in a form that citizens can understand，而C项并无此意。该段第五句只说...may be we can finally stop environmental pollution, and merely hold it back，而不是...will be stopped by the end of this decade，因此D项不对。文章最后一段未涉及选项B的内容，故B项错误。
