Liars usually raise their eyebrows. They also blink (眨眼) a lot and hold their eyes closed longer. Closing the eyes is a way to buy time for the liar to keep their story “perfect”.

说谎者通常会扬起眉毛。在说谎的时候，人们也常常会频繁眨眼睛，闭眼的时间也会更长——闭眼的时间可以让说谎的人更好地“圆谎”

Liars often blush. Blood flows into the cheeks because they are nervous.

说谎者经常脸红。因为说谎的人总会很紧张，这也会让血液更多地流入面部血管。

Liars have fake (假的) smiles. A real smile often causes the eyes to light up or become smaller. This is because more muscles are used when happy.A fake smile is often accompanied (伴随) by “dead” eyes.

撒谎的人总会假笑！真正的笑容会让眼睛发亮或者让眼睛变小——因为开心时候的笑容需要更多的面部肌肉，而假笑总会伴随着相对无神的眼睛。
