One hotnight July, when our new baby wouldn’t or couldn’t sleep, I tried everything I could think of: a warm bottle, songs, gentle rocking. Nothing would settle him. Guessing that I had a long night ahead of me, I brought a portable TV into his room, figuring that watching the late movie was as good a way as any to kill off the hours until dawn. To my surprise, as soon as the TV lit up, the baby quieted right down, his little eyes focused brightly on the tube. Not to waste an opportunity for sleep. I then tip-toed out of the room, leaving him to watch the actors celebrate John Bellushi’ s forty-fifth birthday. My wife and I heard no more of the baby that night, and the next morning when I went into his room, I found him still watching TV himself.
I found in my baby’s behavior a metaphor (暗喻) for the new generation. My wife and I had hiven him some books to examine, but he merely spit upon them. When we read to him, he did not feel comfortable. And
A. They prefer reading to watching TV.
B. They like watching TV only after school.
C. They would rather watch TV than read books.
D. They like their teachers who teach them readin

When stars like our Sun die, they bloat to become red giants and then eject gigantic clouds of gas and dust into space. Increasingly, however, scientists found themselves at a profound loss to explain how exactly dying stars could blow away these clouds. Now astrophysicists propose that unexpected chemical reactions during the formation of stardust could help solve this mystery.
Stars smaller than the Sun and up to eight times as massive die by swelling up into red giants before shedding most of their mass to shrink into very compact, dying embers (灰烬) called white dwarfs. Two kinds of red giants exist-those with lots of carbon, and others richer in oxygen than in carbon. Carbon-rich stars release carbon particles during their death throes. Scientists proposed these pitch-black grains absorb rays from the dying star and get shot into space by starlight, a theory that fit both the observations and computer models.

A. shed most of its mass to the space and shrink into a dwarf directly.
B. break up into pure water and sand.
C. blow its transparent outermost layer into space by starlight.
