Passage 9
One of the most pressing challenges that the United States--and indeed, the world--will face in the next few decades is how to alleviate the growing stress that human activities are placing on the environment. The consequences are just too great to ignore. Wildlife habitats are being degraded or disappearing altogether as new developments take up more land. Plant and animal species are becoming extinct at a greater rate now than at any time in Earth’s history. As many as 30 percent of the world’s fish stocks are overexploited. And the list goes on.
Yet, there is reason to have hope for the future. Advances in computing power and molecular biology are among the tremendous increases in scientific capability that are helping researchers gain a better understanding of these problems. Recent developments in science and technology could provide the basis for some major, and timely actions that would improve our understanding of how
A. How precipitation affects water levels
B. How to prevent outbreaks of infectious diseases
C. How urban development affects the environment
D. How the industrial pollution impacts the environment

| One of the most strikingly apparent
instances of extrasensory perception is the precognitive experience, when a
person has a compelling perception of a coming disaster, news of death of a
loved one, or a communication from a long-lost friend, and the predicted event
then happens. Many who have had such experiences report that the emotional
intensity of the precognition and its subsequent verification provide an
overpowering sense of contact with another realm of reality. I have had such an
experience myself. Many years ago, I awoke in the middle of night in a cold
sweat, with a certain knowledge that a close relative had suddenly died. I was
so gripped with the haunting intensity of the experience that I was afraid to
place a long-distance phone call, (for fear that the relative would trip over
the telephone cord or something and m A. some kind of disaster a person experienced in his childhood B. a vague sense that something will happen and it does happen later C. the prediction of the death of a close friend D. uncertainty about an impending accident [单项选择]Passage Four
