Expressing "except" and "in addition" with "chule… yiwai"

"除了... (以外), 都/也/还..." (chúle... (yǐwài), dōu/yě/hái...) is a pattern used to express "except", "besides", and "in addition".

Here's the basic structure when talking about exceptions:

除了 + Noun Phrase + (以外) + Noun Phrase + 都 + Verb

Here are some examples:

除了妈妈以外，我们全家都去香港。
除了白酒以外，他什么酒都喝。
除了小王以外，我们都会说英语。

The pattern can also be used to mean "in addition". An important note is that either 除了 or 以外 can be omitted from the sentence without losing its meaning.

In this pattern, the structure differs only slightly, substituting 都 with 也:

除了 + Noun Phrase + (以外) + Noun Phrase + 也 + Verb

Here are some examples when using the "in addition" form:

除了日本以外，我还想去台湾旅行。
除了中国人，很多美国人也喜欢赌博。
除了汉堡包以外，她也喜欢吃热狗。
