单选题 I've told you ______ that you cannot go out and play until you've finished your homework.
A. once and for all B. to all intents C. all the way D. in all respects

【正确答案】 C

【答案解析】[解析] 四个选项的意思分别是once and for all断然地，坚决地；无to all intents这种表达方式，应为to all intents and purposes实际上；all the way自始至终，一直的；in all respects在各个方面。句意是，我一直都跟你说，你得做完作业才能出去玩。
