how long have you been playing basketball ?
问题描述:
how long have you been playing basketball ?
A .sometimes B .in tow days C. for tow hours
答
答案:C
解析:由句子中的how long可知此处提问的一段时间.在三个选项中只有for two hours是一段时间,而sometimes是“有时”表示频率,应用how often来提问;in two days表示“两天以后”,应用how soon来提问.只有for two hours用how long提问.
祝开心.
