Everyone sometimes loses things. People often lose things when they are (travel) or when they are in a hurry. That's why there  lost and found offices at airports and (station). What can you do when you lose things? Let me (tell) you.

    In some big (city), there are some lost and found offices. Some clerks(职工) are working in the offices. When they get new thing, they always check it (careful). They want to find out who its owner(主人) is. They are happy(see) an ID card. There is always the owner's photo address on the ID card, so they can find the owner easily.

    When you lose things, first of all, you should think. If you can't do that, just take out (you) mobile phone and wait. Maybe you can get a call.
