你一接起来电话，要先说: Hello, this is XXX company, what can I help you? 或者what can I do for you?

对方会说，我想找XXX ( may I speak to XXX 或者 could you please get XXX on the phone?)

然后，你可以这样说：Hold on please 或者 wait a second please , 然后你就把电话转到那个人那里喽。如果那个人刚好不在，你可以这样说：I am sorry, he/she is not here at the moment, would you like to leave a message for him/her?

大概就是这样了
