断句：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.
语法分析：此句是一个并列句，and连接了两个句子，第一个句子为Infants are wired to look at parents’ faces to try to understand their world，主干是Infants are wired to look at parents’ faces，其中infants是主语，are wired to look at是谓语，parents’ faces是宾语，主干之后的to do 结构to try to understand their world为目的状语，第二个句子为if those faces are blank and unresponsive—as they often are when absorbed in a device—it can be extremely disconcerting for the children，主干为it can be extremely disconcerting，it是主语，can be是系动词，extremely disconcerting是表语，其后for the children为表示对象的状语，主干前面有一个if引导的条件状语从句，其后两个破折号之间as they often are when absorbed in a device是插入语，其所作句子成分为as引导的方式状语。
难点分析：此句难点在于并列句的识别，以及第二个句子中状语从句的识别以及类型的判断。
翻译：婴儿天生就靠观察父母的面孔理解世界，如果父母的面孔毫无表情也无任何反应——当他们全神贯注于电子设备时经常会这样——而这会让孩子们感到非常不安。
