　　例句：

　　At this stage, either of them could win. It's neck-and-neck!
　　英語中還有很多類似結(jié)構(gòu)的短語，比如eye-to-eye, face-to-face, cheek-to-cheek, shoulder-to-shoulder或back-to-back不過他們的意思各不相同！
　　常識(shí)補(bǔ)充：
　　The head can send a wide variety of body language signals. A lowered head can be a defensive posture that occurs as a result of a perceived threat. Touching the face is often seen as a sign of anxiety and people have regular places they touch when they are worried. Our heads are quite heavy, so when we are tired we may use our hand and arm to prop it up. Sometimes when we are thinking, we may also prop up the head.
