正确答案D的并列结构让我感觉很迷,缩略地写一下这个正确答案的句型:among the reasons were A, B and C, and D.(ABCD都是名词)
我记得对于多重并列,要求的结构是A, B, C, and D were among the reasons.(倒装回正常的语序,ABCD都是名词),如果要求更高一级别,我们平时写essay的要求是A, and B, and C, and D were among the reasons(为了避免歧义)
其他的一些情况:
对于SVO完整的句子来说,分隔开才会comma eg: SVO, and SVO
非完整的句子应该是:S1 and S2 VO
我陈述的内容都是根据记忆来的,希望有个人指正并且总结一下and的各种情况。感激不尽
