英语六级考试难度较大，而所有题型中阅读理解的难度相对较低，下面是一篇阅读模拟练习，大家利用考前这段时间好好练习一下，希望能让大家的阅读水平有所提升。 The destruction of our natural resources and contamination of our food supply continue occur, largely because of the extreme difficulty in affixing legal responsibility on those who continue to treat our environment with reckless abandon . Attempts to prevent pollution by legislation, economic incentives and friendly persuasion have been net by lawsuits, personal and industrial denial and long delaysnot 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 industrys and our recognition that protecting mankinds 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. |
