have you got—— ready for the dinner?No,i still need to buy some beef.

问题描述:

have you got—— ready for the dinner?No,i still need to buy some beef.
我觉得anything和everything都可以呀,你准备好晚餐的每个东西了吗?不,我仍需要买些牛肉.你准备好晚餐的任何东西了吗?不,我仍需要买些牛肉.那该选什么呢?

Have you got anything ready for the dinner?意思不是‘你准备好晚餐的任何东西了吗?’而是‘你有给晚餐准备任何东西吗?’
Everything是正确的.
关键在于对方的回答,对方说:‘我还需要这样那样东西’,这样的答复只可能是提问者问:‘全都准备好了么?’如果提问者问:‘你有准备任何东西么?’按照上述剧情,回答者就会说:‘Yes,I have got this this and that...’而不会是:‘No,I still need to buy this this and that etc.’
撇开语法问题不说,我从小在加拿大长大,根据语感绝对应该是Everything.
