A.is B. are C. has been D. have been 答案： BBCDA 1.【B】时态问题。根据句意，主句的动作应在将来某一动作完成时完成，只有只有B的将来完成时较恰当。 我要收藏 2.【B】the moment这里做连词用，表示“就在……时，就在……的那一刻”，前面不需要加介词，如: Thunderous applause broke forth the moment the pop star appeared on the stage. 3.【C】A is to B what C is to D是固定结构，表示“A与B的关系就像C与D的关系一样。” 4.【D】contribute表示“有助于，促成”时，搭配是contribute to doing sth. 5.【A】主谓一致。本句的主语是一个主语从句，即that our environment…behavior,所以应用单数；另外，本句只是表达一般陈述，故用一般现在时即可。
