[简答题]All parents damage their children. It cannot be helped. Youth, like pristine glass, absorbs the prints of its handlers. Some parents smudge, others crack, a few shatter childhoods completely into jagged little pieces, beyond repair. Parents rarely let go of their children, so children let go of them. They move on. They move away. The moments that used to define them—a mother’s approval, a father’s nod—are covered by moments of their own accomplishments. It is not until much later, as the skin sags and the heart weakens, that children understand; their stories, and all their accomplishments, sit atop the stories of their mothers and fathers, stones upon stones, beneath the waters of their lives. Through it all, despite it all, Eddie privately adored his old man, because sons will adore their fathers through even the worst behavior. It is how they learn devotion. Before he can devote himself to God or a woman, a boy will devote himself to his father, even foolishly, even beyond explanati

[单选题]一些人有这样一种思想误区,即只讲“实现自身价值”,不讲“提高自身价值”。人当然天生就有价值,这价值应当重视,但还有待提高。提高不能靠包装与炒作,必须要真正提高质量,具体表现无非就是德与才,这两方面的提高,只有通过克己修身。“玉不琢,不成器”,人不克己修身,如何能成“大器”?所以孟子说:“天将降大任于斯人也,必先苦其心志,劳其筋骨,饿其体肤,空乏其身,行拂乱其所为,所以动心忍性,增益其所不能。”不经艰苦磨炼,如何能“增益其所不能”?

Passage Five

Most typical history courses concentrate on politics, economics, and war. But art history focuses on much more than this because art reflects not only the political values of a people, but also religious beliefs, emotions, and psychology.

B. provides us with information about the daily activities of people in the past
C. gives us an insight into the essential qualities of a time and a place
D. all of the above
