关汉卿这样的艺术家一顽泼，对于社会恶势力，也就从        的敌视，转向居高临下的蔑视。顽泼的君子，已经不会从政治上寻找对手，（        ）。在关汉卿的同行里不失正经的君子，例如，马致远故意把剧名定为《汉宫秋》，并在剧中反复强调一个“汉”字，这在汉人被奴役的时代，显然是一种高雅的“词语风骨”。纪君祥把剧名定为《赵氏孤儿》，让人直接联想到刚刚灭亡的宋代皇帝就是“赵”，因此大家都称得上是“赵氏孤儿”。这儿有一种勇敢的“密码潜藏”，让人佩服。但关汉卿经过观察，暴虐的统治者既看不懂也不明白这种文字游戏，因此，他寻找从整体上        痞子和无赖的方式。

    他的《窦娥冤》为什么能够“感天动地”，因为窦娥是民间底层一个只知平静度日的弱女子，没有任何理由遭到迫害，但迫害还是毫无逻辑、毫无缘由地来了，而且来得那么       、严丝密缝、昏天黑地。原因是她活在一个无赖的世界，上上下下全是无赖。

   如果是政见之恶，总会有前后左右关系的制约，总会有利益集团的暗规，总会有一点点矜持和掩饰，但是，无赖         。这就是窦娥们所遭遇的“无逻辑恐怖”。这正是关汉卿的杰出之处，他不仅仅是逐一批判独裁专制、贪官无道、无赖横行、司法纵容，而是综合成一个整体结论：整个社会就是一个无赖结构。

The young lady (表现) courageously in the face of danger.

    For college students, graduation signals an exciting new beginning. Many students wonder: What do I do now? What career is best for me? Most expert advice on choosing careers boils down to the following points.

Knowing Yourself

    What are your interests? Abilities? Skills? The results may surprise you! These can be useful, but they're not the last word.

Investigating

    Investigating occupations is much more difficult. For most people, there isn't just one ‘right' job, but several that could be satisfying. Talk to people who have occupations that interest you. Find out what they like and dislike about their job.

    Many people choose their careers because they believe strongly in a particular cause. Some might choose to work in areas like medicine, charity or environmental protection. Some have a strong interest in history or a love for the arts. So in cases like these, the field is often chosen first, rather than the occupation itself. So if you've chosen a field, self-assessment will help you find your place in it. Invest some time and effort, and find the right career for you.

A. Try a self-assessment quiz. B. Search through books and Web sites. C. Finding your place. D. But it can also bring a lot of uncertainty and confusion. E. Serious research helps narrow the possibilities F. Research your chosen field carefully. What work needs to be done? What training is needed? G. Then they might think about education, museums or art production.
