单项选择题

As one works with color in a practical, or experimental way, one is impressed by two apparently unrelated facts. Color as seen is a mobile, changeable thing (1) to a large extent on the relationship of the color (2) other colors (3) simultaneously. It is not (4) in its relation to the direct stimulus which (5) it. On the other hand, the properties of surfaces that give (6) to color do not seem to change greatly under a wide variety of illumination color, usually (but not always) looking much the same in artificial light as in daylight. Both of these effects seem to be (7) in large part to the mechanism of color (8) .

When the eye is (9) to a colored area, there is an immediate readjustment of the (10) of the eye to color in and around the area (11) . This readjustment does not promptly affect the color seen but usually does affect the next area to which the (12) is shifted. The longer the time of viewing, the higher the (13) , and the larger the area, the greater the effect will be (14) its persistence in the (15) viewing situation. As indicated by the work of Wright and Schouten, it appears that, at (16) for a first approximation, full adaptation takes place over (17) time if the adapting source is moderately bright and the eye has been in (18) darkness just previously. Also, (19) of the persistence of the effect if the eye is shifted around from one object to another, all of which are at similar brightness or have similar colors, the adaptation will tend to become (20) over the whole eye.

阅读文章片段，回答下面问题。

　　中秋之后，秋风是一天凉比一天，看看将近初冬；我整天的靠着火，也须穿上棉袄了。一天的下半天，没有一个顾客，我正合了眼坐着。忽然间听得一个声音，“温一碗酒。”这声音虽然极低，却很耳熟。看时又全没有人。站起来向外一望，那孔乙己便在柜台下对了门槛坐着。他脸上黑而且瘦，已经不成样子；穿一件破夹袄，盘着两腿，下面垫一个蒲包，用草绳在肩上挂住；见了我，又说道，“温一碗酒。”掌柜也伸出头去，一面说，“孔乙己么？你还欠十九个钱呢！”孔乙己很颓唐的仰面答道，“这……下回还清罢。这一回是现钱，酒要好。”掌柜仍然同平常一样，笑着对他说，“孔乙己，你又偷了东西了！”但他这回却不十分分辩，单说了一句“不要取笑！”“取笑？要是不偷，怎么会打断腿？”孔乙己低声说道，“跌断，跌，跌……”他的眼色，很像恳求掌柜，不要再提。此时已经聚集了几个人，便和掌柜都笑了。我温了酒，端出去，放在门槛上。他从破衣袋里摸出四文大钱，放在我手里，见他满手是泥，原来他便用这手走来的。不一会，他喝完酒，便又在旁人的说笑声中，坐着用这手慢慢走去了。
