1.去掉does.
what he wants to do是宾语从句,是主句动词do的宾语,可翻译为“他想要做的事”.
宾语从句的句序是陈述句序,而不是倒装句序,所以要去掉does.
2.anywhere → somewhere
该句是个肯定句,所以用somewhere,而不能用anywhere.
somewhere beautiful意思是“某个漂亮的地方”
3.a → an
a修饰school,但是art第一个音素是元音/a:/,所以用不定冠词an.
4.May be → Maybe 或 May be → It may be
may be是“情态动词 + 动词原形”结构,它在句中作谓语,但是答句中没有主语,所以可以加个it做主语,或干脆省略成“副词maybe + Beijing or Harbin”结构,其中：Maybe Beijing or Harbin.= Maybe it is Beijing or Harbin.
