Present Perfect Tense | Simple or Continuous? | FOR & SINCE 🤔

简介：

In this lesson, we’ll fix common grammar mistakes made by English students when using the present perfect tense. We’ll explain when to use the present perfect simple versus the present perfect continuous, and when to use ‘since’ and ‘for’. These are both important questions when using the perfect tenses, and this video lesson will answer both of them. Later in the lesson, I’ll also show you how to use ‘for’ and ‘since’ with the present perfect tenses. Both words explain how long something has been happening: use FOR with a period of time and use SINCE with a specific point in time.
