[单选题]筷子在先秦时被称为“梜”，是木字旁，不是“挟”。《礼记?曲礼上》提及“羹之有菜者用梜”，郑玄的注释是“梜，犹箸也”。司马迁的《史记?宋微子世家》谓“纣始为象箸，箕子叹曰：‘彼为象箸，必为玉桮’。”说明“箸”的称呼始自商代。“箸”变成今天的“筷”，有个说法是与江南沿海的船民有关，因为“箸”与“住”同音，对船民而言有不吉利的意思，所以反其意称“箸”为“快儿”。又因为大多数“快儿”是用竹子所做，于是在“快”字上加了竹字头，成为“筷子”。
对以上文字概括最准确的一项是：
A.“筷子”在史书中的记载
B.“筷子”名称的演变历史
C.“筷子”所蕴含的文化寓意
D.“筷子”与江南船民的渊源

[单项选择] We sometimes think humans are uniquely vulnerable to anxiety, but stress seems to affect the immune defenses of lower animals too. In one experiment, for example, behavioral immunologist (免疫学家) Mark Laudenslager, at the University of Denver, gave mild electric shocks to 24 rats. Half the animals could switch off the current by turning a wheel in their enclosure, while the other haft could not. The rats in the two groups were paired so that each time one rat turned the wheel it protected both itself and its helpless partner from the shock. Laudenslager found that the immune response was depressed below normal in the helpless rats but not in those that could turn off the electricity. What he has demonstrated, he believes, is that lack of control over an event, not the experience itself, is what weakens the immune system.
Other researchers agree. Jay Weiss, a psychologist at Duke University School of Medicine, has shown that animals who are allowed to control unpleasant stimuli d

[单选题]Why is （请作答此空）fun What delights may its practitioner expect as his reward? First is the sheer joy of making things. As the child delights in his mud pie, so the adult enjoys building things, especially things of his own design. Second is the pleasure of making things that are useful to other people. Third is the fascination of fashioning complex puzzle-like objects of interlocking moving parts and watching them work in subtle cycles, playing out the consequences of principles built in from the beginning. Fourth is the joy of always learning, which springs from the（ ） nature of the task. In one way or another the problem is ever new, and its solver learns something: sometimes（ ） , sometimes theoretical, and sometimes both. Finally, there is the delight of working in such a tractable medium. The（ ）, like the poet, works only slightly removed from pure thought-stuff. Few media of creation are so flexible, so easy to polish and rework, so readily capable of realizing grand conceptual structures.Yet the program （ ）, unlike the poet's words, is real in the sense that it moves and works, producing visible outputs separate from the construct itself. It prints results, draws pictures, produces sounds, moves arms. Programming then is fun because it gratifies creative longings built deep within us and delights sensibilities we have in common with all men.
A.programming
B.composing
C.working
D.writing
