单选题 Whether the eyes are "the windows 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 percent of them drew people with mouths, but 99 percent of them drew people with eyes. In Japan, however, where babies are carried on their mother"s back, infants do not acquire as much attachment to eyes as they do in other cultures. As a result, Japanese adults make little use of the face either to encode (把……编码) or decode(理解) meaning. In fact, Argyle reveals that the "proper place to focus one"s gaze during a conversation in Japan is on the neck of one"s conversation partner."
The role of eye contact in a conversational exchange between two Americans is well defined; speakers make contact with the eyes of their listener for about one second, then glance away as they talk; in a few moments they re-establish eye contact with the listener or reassure the selves that their audience is still attentive, then shift their gaze away once more. Listeners, meanwhile, keep their eyes on the face of the speaker, allowing themselves to glance away only briefly. It is important that they be looking at the speaker at the precise moment when the speaker reestablishes eye contact: if they are not looking, the speaker assumes that they are disinterested and either will pause until eye contact is resumed or will terminate the conversation. Just how critical this eye maneuvering is to the maintenance of conversational flow becomes evident when two speakers are wearing dark glasses: there may be a sort of traffic jam of words caused by interruption, false starts, and unpredictable pauses.

单选题 The author is convinced that the eyes are ______.

单选题 Babies will not be stimulated to smile by a person ______.

【正确答案】 C

【答案解析】[解析] 根据第一段中的第二、三、四句“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.”判断出C项与第四句后半句“脸侧对着孩子的人不会引起婴儿发笑”相符，故为正确答案。

单选题 According to the passage, the Japanese fix their gaze on their conversation partner"s neck because ______.

单选题 According to the passage, a conversation between two Americans may break down due to ______.

【正确答案】 C

【答案解析】[解析] 根据文章第二段第三句“It is important that they be looking at the speaker at the precise moment when the speaker reestablishes eye contact: if they are not looking，the speaker assumes that they are disinterested and either will pause until eye contact is resumed or will terminate the conversation.”(在说话人重新进行目光接触时，听话人看着说话人非常重要。如果他们不看说话人，对方会认为他们不感兴趣。说话人要么会停止说话直到听话人恢复目光接触，要么就会终止会话。)推断出C项“中止目光接触的时机把握不当”符合题意。
