Whether the eyes are “the window of the soul” is debatable; that they are intensely important in interpersonal communication is a fact. During the first two months of a baby’s life, the stimulus that produces a smile is a pair of eyes. The eyes need not be real： a mask with two dots will produce a smile. Significantly, a real human face with eyes covered will not motivate a smile, nor will the sight of only one eye when the face is presented in profile. This attraction to eyes as opposed to the nose or mouth continues as the baby matures. In one study, when American four-year-olds were asked to draw people, 75% of them drew people with mouths, but 99% of them drew people with eyes. In Japan, however, where babies are on their mother’s back, infants do not acquire as much.

题1: A. attachment B.alternation C.alleviation D.attraction
网上不少选A的，想问D为何不对啊，前文标粗的我看也看用attraction to eyes的。
this attraction to eyes...... 理解为 this attraction （for babies）to eyes 即 双眼对幼儿的吸引力。
抛开这个，单独剖析选项：
你可以 acquire，develop or form an attachment，获得，进步出或形成一种依恋爱绪
但不可以 acquire，develop or form an attraction，获得，进步出或形成一种吸引力
当sb做主语时，只能“感受feel，发现see” 吸引力attraction。
即只能被动同意，不可以主动改变。
