大家可以练习下如何用以上的词汇完成下面的短文：
Body language can be very informative, but if you ______ ______ ______ when you interpret a particular _______, you may _______ what it means. For example, people who look away to avoid _______ _______ may not necessarily be lying: they could just be very sky. To understand body language, therefore, we need to _______ _______ ________ of behaviour that a person _______. With lying, for example, ________ ________ for any or all of these:
1. avoidance of eye contact
2. _______ _______
3. biting fingernails
4. ________ a lot
5. ________ hand gestures
除以上填空词汇，黑体字也是非常有用但中国学生不擅长使用的词汇。
