52. While all states face similar industrial waste problems, the predominating industries and the regulatory environment of the states obviously determines the types and amounts of waste produced, as well as the cost of disposal. (D) each state faces similar industrial waste problems, the predominant industries and the regulatory environment of each state obviously determines (E) all states face similar industrial waste problems, the predominant industries and the regulatory environment of each state obviously determine the answer is E. 没问题。但我想问一个关于主谓一致的问题, og解释说D主谓不一致,the predominant industries and the regulatory environment of each state 要复数determine。 我想问为什么不是单数呢 A and B of each state, 重点在 each state!每个州(的支柱产业和环境监督),所以单数! 请大家帮忙。 |
