Which are you going to do 这句话有错误吗?

Which city are you going?还是Which city are you going to? which university are you going to apply? or What are you going to university?哪个对 Which kind of food are you going to investigate____your project Which middle school are you going to go to? which beach are you going to?什么意思 which dress are you going to wear today 还是which dress are you going to put on today Which beach do you usually go和Which beach are you going to which one are you going to?可以说成：which one will you go? which country are you going to visit if you have a chance如上,中文翻译 Which beach are you going to?结尾为何要加to那“Where are you going ”呢？是以“which”提问的才加“to”吗？ Which camp are you going to sign up for?改句 Which camp are you going to__ __?是不是join in? Which beach are you going to Which room do you live in.这2句里分别哪个是介词 when are you going? You are going you are going down How are you going Where are you going? When are you going
