今日长难句：

选自"The Body"

Oxytocin, to take one example, is well known for its role in generating feelings of attachment and affection—it is sometimes called “the hug hormone”—but it also plays an important part in facial recognition, in directing contractions of the uterus in childbirth, in interpreting the moods of people around us, and in initiating the production of milk by nursing mothers.

这句话第一个主句当中sth is well known for sth表示某事物在某方面非常知名，写作文的时候如果想举例除了用for example，for instance，也可以用to take one example这样的表达，但这句话的语义重点不在第一个分句而是后半句的转折部分，but it also plays an important part in，其中it指代的还是主语，注意这里用part替代role的作用就是避免用词的重复，之后由于是一系列的排比，为了表达简洁，作者做出了一系列省略（省略了it plays an important part），—but it also plays an important part in facial recognition催产素在面部识别上起到重要作用, in directing contractions of the uterus in childbirth催产素在指导分娩时子宫的收缩时起到重要作用, in interpreting the moods of people around us催产素在理解我们周围人的情绪时起到重要作用, and in initiating the production of milk by nursing mothers.在哺乳母亲开始产奶的过程中，也起着重要的作用。

总结下，这句话由3个分句组成，3个动词分别为is，is called和plays。整句话意思是：以催产素为例，它以产生依恋和亲情的作用而广为人知——有时被称为“拥抱激素”——但它在面部识别，指导分娩时子宫的收缩，在理解我们周围人的情绪，以及在哺乳母亲开始产奶的过程中，也起着重要的作用。
