throw 改为threw
或者asked改为asks
whether引导的宾语从句要求前后时态必须一致，

He asked his mother whether he could throw them away.这句话的情况非常明显，首先分析句式。“ask..if”句式表达的意思是询问是否可以被允许做某事，那么if后面的部分一定是询问者决定要做的事情，这时候一般用could，表示询问是否被允许。而“ask..whether”多用于请示的含义，即发问者不知道要怎样做，因此请被询问者作出决议，这时候后面一般用should，表示没有感情色彩倾向的询问。因此，本句中，可以把could改为should，也可以把whether改为if，都成立。至于前面一位朋友的观点，此处的事态已经一致，无需更改。

the sentence is correct, you can also use 'if' instead of 'whether' .
so don't think so much

throw 改为threw
