Question

We have decided to accept the proposal that he ________ his new theory.

A. offer B. offers C. offered D. would offer为什么用选择A,谢谢

Answer 1

A。
这句话是一句同位语从句。所谓的同位语，也就是对前文提到的成分（一般是名词，类似建议、意见、观点等词）起到解释说明作用。
这句话中的that 引导的从句是充当proposal（建议）的同位语。
在同位语句子中经常用到情态动词should的特殊用法，即在这类句子中，should+动词原形，should经常省略。这个句子中从句部分完整的应该是he should offer his new theory，省略了should，即that he offer his new theory。

decide to do 决定做某事
accept proposal 接受建议。

不懂可以追问。
