Infants are wired to look at parents' faces to try to understand their world, and if those faces are blank and unresponsive—as they often are when absorbed in a device—it can be extremely disconcerting for the children. Radesky cites the “still face experiment” devised by developmental psychologist Ed Tronick in the 1970s. In it, a mother is asked to interact with her child in a normal way before putting on blank express and not giving then any visual social feedback. The child becomes increasingly distressed as he tries to capture her mother's attention. “Parents don't have to be exquisitely present at all times, but there needs to be a balance and parents need to be responsive and sensitive to a child's verbal or nonverbal expressions of an emotional need,” says Radesky.(2017年英語二text2)

解析:根據該題題干信息中的“cites 事例 to show that___”,可以判斷該題很可能是一個例證題。我們根據事例“still face experiment”定位到該段第二句話,那么從第二句話開始,后面就是在具體敘述這個事例了。利用我們剛才談到的技巧,我們可以利用第一句話的觀點直接解題。第一句的主干是:嬰兒生來就靠觀察父母的面孔理解世界,如果這些面孔毫無表情也無任何反應,這會讓孩子們感到非常不安。理解了這句話其實我們就可以直接選出與之一致的B選項了:父母需要回應孩子的情感需求。
