谁能解释一下为什么答案选D？

Today is Thursday, and Tom lost his bike last Sunday. We may say “_____”.A. Tom has lost his bike four days ago B. Tom has lost his bike for four days C. Tom lost his bike for four daysD. It’s four days since Tom lost his bike

Answer 1

今天星期三 tom上个星期日丢了车 我们可以说 A 有ago 这是一般过去式的标志 所以不能用完成时 而且lost是短暂性动词 不能用完成时所以B不入选 关于C 本身就是错误用法 for+一段时间 要用完成时 D是从句 入选 如果有这样的答案 . Tom has been lost his bike for four days 此处lost为形容词 也是正确答案

Answer 2

A有语法错误，four years ago应该要用一般过去式，不能用在现在完成时；C有语法错误，for four days应该要用现在完成时，不能用在一般过去时；而B我不是很清楚，应该是lost his bike这个动作是瞬间动作，不能用于现在完成时，这句应该可以改为Tom's bike has been lost for four days.D,since的主句应该用现在完成时 ，-'s的祥写是has
