23.6 have come in (present perfect)
23.6.1 Mr. Smith and Ms. Kim are teachers at a community college. It is winter and the
weather is very bad today. It’s snowing and the wind is very strong.
Mr. Smith: Ms. Kim, have your students come in yet?
Ms. Kim: About half of them have come in, but many of them haven’t
come in because the weather is so bad today.
Mr. Smith: The college should close for the day. It’s dangerous for
students to be driving in these conditions
Ms. Kim: I agree.
