[简答题]
If I wanted to, I could come up with a dozen excuses. I was
fired after a long day of work. Or maybe I was hungry. The simple truth is, when
I walked into the living room and my 12-year-old son looked up at me and said.
"I love you," I didn’t know what to say. For several long seconds all I could do
was standing there and staring down at him, waiting for the other shoe to drop.
He must need help with his homework was my first thought. Or he’s going to hit
me up for an advance on his allowance. Or he’s assassinated his brother—I always
knew it would happen someday—and he’s trying to prepare me gently for the news.
Finally I asked, "What do you want " He laughed, and started to run from the
room. But I called him back. "Hey, what was that all about " I demanded. "
Nothing," he said, grinning, "My health teacher said we should, tell our parents
that we love them and see what they say. It’s sort of an experiment. "
The next day I called his teacher to

[简答题]
The term "Ice Age" may give a wrong impression. (46) The epoch that spanned the 1.5 to 2.0 million years prior to the current geologic epoch was not one long continuous process, but a period of fluctuating climate with ice advances interrupted by times of climate not very different from the climate experienced now. Ice sheets that derived from an ice cap centered on northern Scandinavia reached southward to Central Europe. And beyond the margins of the ice sheets, climatic oscillations affected most of the rest of the world; for example, in the deserts, periods of wetter conditions (pluvials) contrasted with drier, interpluvial periods. (47) Although the time involved is so short, about 0.04 percent of the total age of the Earth, the amount of attention devoted has been incredibly large, probably because of its immediacy, and because the epoch largely coincides with the appearance on Earth of humans and their immediate ancestors.
