PRESENT PERFECT: CHANGE OVER TIME

Happy Monday, everyone! I hope your weekend was relaxing. 

This week, we are focusing on some grammar and looking at the Present Perfect. 

Remember that the Present Perfect uses this form:

HAS / HAVE past participle

We have looked at this several times because this is a tense many students have questions about. Each day of this week, we will look at a different way we use the Present Perfect. Today we will look at using it for CHANGE OVER A PERIOD OF TIME. 

Example 1: People have become more aware of how bad drinking straws are for the environment. 

Example 2: The government has begun looking at the long-term effects of some common prescription drugs. 

We often use the word SINCE in these situations. 

Example 3: Since we watched the documentary about the environment, we have started eating more organic foods. 

Example 4: He has become more interested in literature and theatre since he took a class about Shakespeare. 

That's all for today. Tomorrow we will look at another way to use the Present Perfect. Have a great day!
