解答
loudly 用副词,排除BC
宾语从句不可以用if 代替whether,排除D
所以选A那两个不是可以互换的吗?在宾语从句中不行!那在什么中可以?一般情况下,if和whether可以互换,但以下几种情况只能用whether:1、在不定式前:Whether to go there or not hasn'tbeen decided.2、在介词前:It depends on whether it is going to rain.3、在选择疑问句中:They are talking about whether to go there or not.4、 当宾语从句提到句首时:Whether it is true or not,I can’t tell.这里题属于哪种情况?这里属于第四种情况。如果满意,请点击下面的“选为满意答案”,谢谢您!如果不满意,欢迎追问。
