问题     Something big is happening to the human race—something that could be called The Great Transformation.
    The Transformation consists of all the changes that are occurring in human life due to advancing technology. For thousands of years such progress occurred slowly. Now, everything is changing so fast that you may find yourself wondering where all this progress is really leading.
    Fifty years ago, few people could even imagine things like computers and lasers. Today, a host of newly emerging technologies such as artificial intelligence and genetic engineering are opening up all kinds of new paths for technologists.
    Like it or not, our advancing technology has made us masters of the earth. We not only dominate all the other animals, but are reshaping the world’s plant life and even its soil and rocks, its waters and surrounding air. Mountains are being dug up to provide minerals and stone for buildings. The very ground under our feet is washing away as we chop down the forests, plow up the fields, and excavate foundations for our buildings.
    Human junk is cluttering up not only the land but even the bottom of the sea. And so many chemicals are being released into the air by human activities that scientists worry that the entire globe may warm, causing the polar icecaps to melt and ocean waters to flood vast areas of the land.
    During the twentieth century, advancing technology has enabled man to reach thousands of feet into the ocean depths and to climb the highest mountains. Mount Everest, the highest mountain of all, resisted all climbers until the 1950’s. Now man is reaching beyond Earth to the moon, Mars, and the stars.
    No one knows what the Great Transformation means or where it will ultimately lead. But one thing is sure: human life 50 years from now will be very different from what it is today.
    It’s also worth noting that our amazing technology is posing an increasingly insistent question: When we can do so many things, how can we possibly decide what we really should do. When humans were relatively powerless, they didn’t have to make the choices they have to make today.
    Technology gives us the power to build a magnificent new civilization—if we can just agree on what we want it to be. But today, there is little global agreement on goals and how we should achieve them.
    So it remains to be seen what will happen as a result of our technology. Pessimists worry that we will use the technology eventually to blow ourselves up. But they have been saying that for decades, and so far we have escaped. Whether we will continue to do so remains unknown—but we can continue to hope.
选项 A、artificial intelligence and genetic engineering.
B、the shortage of natural resources.
C、the development of practical science.
D、unknown reasons.
答案C
解析 事实细节题。本文第二段首句指出"这一变革包括由科技进步引起的发生在人们生活中的所有改变"。根据常识可知，科技属于应用科学，因此产生大变革的原因就是应用科学的发展。
