there is nothing to do expect do

There is nothing to do EXCEPT wait.
1 你的原句是：（比如说）
There is nothing to do EXCEPT THAT we have to wait.-------由於句子有点lengthy,英语民族speakers就省略了 THAT we have to .
2 there is nothing to do except do ------翻译是“只能做- - - -,不得不做 -- - - ”
3 except在这里是介词.用的人多了,就成了习惯用法,所以是do,不是doing.
