下面题目为什么选择B?我认为选A
-- So, what big changes do you think we'll see in the future, say the next fifty years?
-- We'll probably ____ (land) on Mars within the next fifty years.
A have landed B land

Answer

A似乎更好，意思表达更贴切 
问问老外 

有个老外说选A，英国人，我还问了其他人，看看是不是有差别
跟老外讨论了下，从意思上说，have landed更好，不过，我看这个地方要考的是within the next fifty years，这不是一个时间点，如果要表示50年内已经登陆火星，更好的答案是“have been landed"

Answer

will 后面用动词原形
