objection to doing sth. 以下来自词典: objection [Eb5dVekF(E)n] n. 反对(某人或某事) He has a strong objection to getting up early. 他强烈反对早起。 My objection is that he is too young. 我反对是因为他太年轻。 学习学习 同意二楼 同意二楼 have(谓语)+to(介词)+名词性质的词(介词宾语) 所以 (B) to hearing C) to having heard 都合法 继续排除,结合整句意思, 注意again这个关键词语 意味着听过一次,有了不排斥的原因,所以要听第二次,还未听第二次,所以排除完成时。排除C) to having heard is that clear? |
