“特殊疑問詞+動詞不定式”的用法歸納

Where to live is a problem.當(dāng)賓語，常接在forget,findout,discuss,decide,tell,teach,know, learn,wonde

2、r, remember 等動詞之后作賓語如： We must know what to say at a meeting. He could not tell whom to trust. Do you know how to play bridge?當(dāng)表語，如： The problem is where to find thefinancial aid. The question is who to elect.當(dāng)名詞同位語，如： Tom had no idea which book to read first. The question whether to confess trouble
