1. You think you're so smooth – the James Bond of covert job searching. Where he used wrist-mounted dart guns and camera-implanted rings, you have deceptive "dentist appointments" and a conveniently angled computer monitor to conceal secret résumé tweaking.

3. n. 扩大，膨胀，扩充
5. The two pleasure devices both made of bronze date back more than 2000 years to China's Han Dynasty (206 BC–220 AD).
