The plant is dead. I ____ it more water. A．will give B．would have given C．must give D．should have given

Answer 1

D

试题分析：考查情态动词用法。句意：这棵植物死掉来了。我本应该给它浇更多的水的。故D正确。根据句意说明是对过去的情况进行说明的，使用“情态动词+have done”,would have done本会做某事，实际上却未作；should have done本应该做某事，实际上却未作； 点评：本题是高考必考考点，一定要牢记句型意思。must have done过去肯定做了某事。 should have done 本应该做而实际未做。 can’t have done 过去不可能做了某事。shouldn’t have done 本不应该做而实际做了。 need have done 本有必要做某事 needn’t have done 本没有必要做某事。注意没有 mustn’t have done的形式
