Welcome to the second half of Fall Semester. Yes, we're half finished with the first semester at our new campus.
Today there is a Teachers' Meeting from 9:45 - 10:45 a.m. Our class will start a few minutes late.
Our next topic is 'used to' meaning something you did at some past time but don't do now. For example, "When I was a child, I used to ride my bicycle every day."
Be careful: 'be used to' means be familiar with or accustomed to something.
It has a very different meaning, but sounds (almost) the same.
Here's some more practice with the
present perfect vs. past tense
