First order logic

I have a small problem with the first order logic, in particular, predicate logic

Let us take this sentence as an example:

Each teacher has given a form to each student.

From this sentence, can we have different reading?

This is my try to solve such problem; I did not know whether this is the answer for such question:
Quote:
Every Teacher has given a form to each Student.

(∀x)Teacher(x)^(∀y) Student(y)^(∃z)Form(z)^Give(x,y,z)

If X is a Student then he has received a form from a teacher

Student(x)→(∃y) Teacher(y)^(∃z)Form(z)^Give(x,y,z)

If X is a Teacher then he has gave a form for all his students

Teacher(x)→(∀y) Student(y)^(∃z)Form(z)^Give(x,y,z)

If X is a form then a teacher gave it to all student.

Form(x)→(∀y) Employer(y)^(∃z)Teacher(z)^Give(x,y,z)
