这几天看书用英语怎么说

这几天看书用英语可以说 "I have been reading books these days (or recently)." 这个短语来源于英语中的常见表达方式，表示在过去一段时间里一直做某事。例如：

I have been studying for my exams these days. (我这几天一直在为考试复习。)
She has been working on a new project recently. (她最近一直在做一个新项目。)
They have been traveling around Europe for the past month. (他们过去一个月一直在欧洲旅行。)

希望以上回答对您有帮助。
