ask后面what引导的句子作为ask的双宾语之一,是宾语从句,所以需要陈述句语序 应该更改为: We asked them what they did last weekend. We (should/will) ask them what they are doing I askd her what she had seen.
正确的应该是这样:We asked them what they did last weekend. We ask them what they are doing. I ask her what she sees. 因为ask 可接双宾语,即ask sb sth. 此时的sth 是以what 引导的一个名词性从句做宾语,就不能再以疑问句的形式出现,而应改为陈述句的形式。
