1 . In the United States，many teachers keep fish，hamsters(仓鼠)，and other animals in their classrooms.Teachers say students learn important lessons from the animals.More than 70 percent of teachers who have classroom pets say the animals help students learn responsibility.Research also shows that classroom pets can reduce stress.

“Pets can comfort kids who are having a bad day,”says Lisa Robbins，who works fora group called Pets in the Classroom.

But others think pets should be expelled from classrooms. In January，the Durango School District in Colorado began following a no-pet policy(政策).Now animals can be brought into Durango schools for certain lessons，but they can't stay.Officials were worried that animals might create problems for kids with allergies(过敏症).They were also concerned about the animals getting proper care.

Here's what two of our readers think.

Having classroom pets gives students a fun way to learn about animals. In my class last year，we had a class pet named Elliot.Our teacher also used him to teach us about different subjects.For example，in math，we calculated (计算)how much it costs to feed Elliot for a year.

Pets also help kids learn how to work as a team. My classmates and I took turns feeding Elliot and cleaning his tank,

If teachers are worried about students with allergies，they could get pets that don't have fur.

Classroom pets can take away valuable class time.Some students might have a hard time focusing on the teacher when there are animals in the room.

Plus，having a classroom pet can cause safety problems. You never know how an animal will react to students.Even a cute little hamster might hurt a kid who sticks his or her hand in its cage.
