ncial aid. The question is who to elect. ⑷當(dāng)名詞同位語,如: Tom had no idea which book to read first. Do you have a rough impression how to do it? ⑸當(dāng)賓語補(bǔ)足語,如: Jim is not sure whose to choose.

Jack did not know where to find such a good teacher./ Jack did not know where he could find such a good teacher. 有些動詞,如“ask, show, tell, advise, inform, teach”等,可以先有個賓語,然后才接著加上適當(dāng)?shù)摹耙蓡栐~+不定式動詞” 結(jié)構(gòu)。例如: The chief technician showed the apprentice how to repair the machine.
