39、.=she cant decide which she will buy.反之，如果主句中的主语与宾语从句中的主语一致时，宾语从句（由疑问词引导）通常可以与“疑问词+不定式”互相转换。如：Idont know what I should do.=I dont know what to do.如果不一致就不能转换。I want to know what Mary will do.(不能说:I want to know what to do.)Unit4 Amazing ScienceTopic1【重点短语】1. go around环绕2. sendinto=send upinto把送入.3. c
