[問題] what to do 和how to do的用法?

[chensir (Stephanie)]

Tom found himself in trouble, and he didn't know _________.

      (A) what to do (B)how to do



       我想請問這題要選A還是B呢?

       因為如果還原成what he should do 或是how he should do不是都通順嗎?

       謝謝回答了!!

推 kowtow:i don't know what to do=i don't know how to do "it"
→ kowtow:除非how to後面接的動詞是不及物像i don't know how to sin
推 weiiwei:how to do語意上應該用於"有明確的一件事但不知怎麼做"吧
→ kowtow:g.不然how to 接的動詞後面要有"東西"
→ weiiwei:而在此句中用"what to do"來表達"不知道該怎麼辦"比較通順
→ weiiwei:唷！ ^^
→ kowtow:嗯weiwei說的也對.how to do是有明確的東西.只是do後面要加
→ weiiwei:我表達的意思跟樓上一樣！！
→ kowtow:"東西"
