Present Perfect or Past Simple Today, talking to my colleague and discussing english I was kind of surprised. The thing is that I always thought Present perfect is used when there are words as: - this month - this spring - this week - today and so on, while past simple is used when you see: - last month - last spring - last week - yesterday But today I saw an example: She has traveled to Alaska twice this month (she might travel again) She traveled to Alaska twice this month (she probably won't travel again this month) So what do you think of it?
