(B)


Directions: Translate the following passage into Chinese.
To make your first encounter a positive one, start with a firm handshake. If the interviewer doesn’t initiate the gesture, offer your hand first. Whenever you .have a choice of seats, select a chair beside his or her desk, as opposed to one across from it. That way there are no barriers between the two of you and the effect is somewhat less confrontational. If you must sit facing the desk, shift your chair slightly as you sit down, or angle your body in the chair so you’re not directly in front of your interviewer.
