你好，

I want to make a clarification. Those re-opened assignments are for the students who didn't turn in on the due day. Since we won't go back to school before end of school year, your grades are depended on the work you turn in. Those students who didn't turn in the assignments, please finish doing the reopened assignments, turn them in as soon as possible, and also do the current assignment. For those students who has turned in every assignment, you don't need to do it again. Just continue to do the current assignment.
