Question

—What did your teacher say this morning? —She told us___

—What did your teacher say this morning?
—She told us___
A.whether we had too much homework B.that we would have a test soon
为什么不选A？

Answer 1

你好;
这里是答句, 在答句中不能有疑问词 whether , 如果这里用了whether 的话,就是一个被转述的问句了, 那么就应该是 She ask us whether we had too much homework .

所以不能选A

Answer 2

不选 A 的原因，不是语法，而是逻辑。
—What did your teacher say this morning?今早你们老师说什么了？
—She told us___
A.whether we had too much homework 她告诉我们是否有太多作业（如果老师真的给你们太多作业，那她肯定不认为那是”太多“。从语法上来讲，没问题）
B.that we would have a test soon 她告诉我们近期会有考试
如果A 改成，whether we had any homework，她告诉我们是否有作业，这样就可以了。

Answer 3

whether是‘是否’的意思 told是肯定的语气 翻译不通

Answer 4

我也不知道。
