[单项选择]Now and again I have had horrible dreams, but not enough of them to make me lose my delight in dreams. To begin with, I like the idea of dreaming, of going to bed and lying still and then, by some queer magic, wandering into another kind of existence. As a child I could never understand why grown-ups took dreaming so calmly when they could make such a fuss about any holiday. This still puzzles me. I am mystified (迷惑的) by people who say they never dream and appear to have no interest in the subject. It is much more astonishing than if they said they never went out for a walk. Most people or at least more Western Europeans do not seem to accept dreaming as part of their lives. They appear to see it as an irritating little habit, like sneezing or yawning.
I have never understood this. My dream life does not seem as important as my waking life, if only because there is far less of it, but to me it is important. As if there were at least two extra continents added to the world
A. have ignored the important aspects of dreams
B. don’t know how to enjoy life in their dreams
C. value dreams very highly
D. think of sneezing when thinking of dreams

The Ice Age

Twenty thousand years ago, the earth was held in control by relentlessly (不宽容地) probing fingers of ice that drew power from frigid strongholds in the north and crept southwestward to bury forests, fields, and mountains. Landscapes that were violated by the slowly moving glaciers(冰川)would carry the scars of this advance far into the future. Temperatures dropped deeply, and land surfaces in many parts of the world were depressed by the unrelenting weight of the thrusting ice. At the same time, so much was drawn from the oceans to form these huge glaciers that sea levels around the world fell by three hundred and fifty feet, and large areas of the continental shelf became dry land.
