介绍:
THE CLOCK TEST: If you feel like he or she's been watching you, suddenly look at the clock then quickly look at him/her. If they're looking at the clock then it's because they were watching you and following your eyes is a natural reflex to a sudden change of movement.
时钟测试：要是你感到他/她在看你，那就试试突然抬头看钟然后又转头看他/她。如果他/她也抬头看钟，说明他/她刚才确实在看你。要知道，跟着你的视线走是突然动作的最自然不过的反应了。
