Directions: Translate the following passage into Chinese.
Monitor your body language to make sure you don’t seem too desperate for the job, or too eager to please. Keep a poker face in business situations. Inappropriate smiling is the most common example of a nonverbal behavior that undercuts verbal messages—making you appear weak and unassertive. Good eye contact is also important. One study found that job applicants who make more eye contact are perceived as more alert, dependable, confident and responsible.
