    Here,

    "be used to" is in passive voice, so "to" is not a preposition, but uses with "be used" to form an infinitive. It means "過去曾經如何如何"

    However, if you use it this way:

    He is not used to walking for a long distances.

    in the above sentence, "to" is a preposition, so you will following with

    noun, pronoun, or noun equilibrium (such as V-ing,...), it means "習慣於

    "

    If your sentence is written as:

    They are used to greeting a friend and relative.

    then you will use "greeting".

    However, your questioned sentence uses "can be used to greet". It means "something are used to greet". In Chinese "它們可以被用來迎接朋友或親戚".

    In the above case, "to" is to form infinitive, like "to greet", not a preposition.

    Of course, if in the sentence "they are used to greeting a friend or relative", "are used to" means "被用來", then you still need to follow with V, not V-ing. To precisely determine the function of "to", you need to have the context and the feeling of English.

    Telling you all these rules without the context and the feeling, you might get even more confused.

    The only way to get it right is to practice and read more.
