Помогите, пожалуйста, очень срочно!!! Выписать из текста предложения с пассивным залогом.

Past experience has shown that students starting the course have two areas of anxiety: the first is with how their work is going to be assessed, and the second is how best to study for the course.
As you will know if you've read the information sent to the course participants before the start of the course, you will be required to supply four pieces of written work for assessment purposes.
Each of these Tutor Marked Assignments or TMA's as we call them must be submitted by the date laid down in your course details, and it's absolutely necessary to meet these requirement.
No late assignments will be marked, whatever the reason for their being late, and your grade for the course will be affected.
Word length is always laid down, and for the first TMA it is 2,000 words.
If this is not possible, then please write as clearly as you can, allowing good margins so that comments can be written in.
