[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.

[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”？这段文字意在（）。

C.批评某些人一味自我包装炒作的行为 -

Passage Five
A study of art history might be a good way to learn more about a culture than is possible to learn in general history classes. 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. In addition, information about the daily activities of our ancestors--or of people very different from our own--can be provided by art. In short, art expresses the essential qualities of a time and a place, and a study of it clearly offers us a deeper understanding than can be found in most history books.
In history books, objective information about the political life of a country is presented; that is, facts about politics are given, but opinions are not expressed. Art, on the other hand, is subjective: it reflects emotions and opinions. The great Spanish painter Francisco Goya was p
A. shows us the religious and emotions of a people in addition to political values

C. gives us an insight into the essential qualities of a time and a place
