题目

Having been through nearly 3 years of time on campus,I have obtained considerable experience
语法有什么问题么...我从小语法就差,大家看这两句话都是现在完成时.

答案

你的句子就语法来说没有问题.但从语感来说,Having been through nearly 3 years of time on campus,I have obtained considerable experience应该改写成：Having spent nearly 3 years on campus,I have gained considerable experience.或者说：Some three years spent on campus has enabled me to gain considerable experience.
