    the purpose of adding words in the process of translation is to add more meanings to the original sentence.

    one type of addition--semantic completion--is out of the need of making the meaning complete or achieving rhetorical effect.

    "it is the same old story of not being grateful for what we have until we lose it, of not being conscious of health until we are ill." in this sentence, “health” can be translated into "健康之宝贵”.

    when there are idioms in the target language with the same meaning and similar images, it is the best option for us to borrow these idioms in translation.

    when there are idioms in the target language with the same meaning yet different images, borrowing cannot be used.

    when translating chinese idioms which are related to classical allusions that are unfamiliar to the target readers, we can use liberal translation to improve the readability for the target readers.

    slang refers to informal language consisting of words and expressions that are not considered appropriate for formal occasions.

    slangs can be ided into three main categories: 1. euphemi 2. swearword 3. idiom

    "she is five months gone" is a euphemi for "she is dead for five months".

    we can translate the sentence "what is the geography of the house?" into "这个房子在什么地理位置?”

    when translating swearwords, we need to pay attention to the emotion and tone of the original and avoid literal translation.
