After the September 11 terrorist attacks, some high schools in America wanted the students to pledge allegiance(宣誓效忠) to the flag. Is it necessary or not? Let’s see how the kids think of this requirement.

Lea Mouallem, Marymount High School

I believe that saying the Pledge of Allegiance is a way of reminding our country that no matter what happens, we are united. I don’t think our president wants us to go and join the army now, but he wants to tell us that we will be able to overcome the disaster as a whole nation that is working together.

Harry Chin, 15, Culver City High School

I am not for the Pledge of Allegiance and I am not against the Pledge of Allegiance because I just say it so many times that it loses meaning. I say it every day at school in the second period. It doesn’t mean anything any more.

David Tran, 15, Warren High School.

The Pledge of Allegiance is another sign of country. We should have some respect to it. In many schools, we don’t say the Pledge every morning-we just stand up and let the National anthem ring through the silence. We said the Pledge of Allegiance on Sept. 12.

Danny Maryanor, 16, Santa Monica High School

I wonder why we were suddenly asked to recite the Pledge when many of us stopped after elementary school; and the Pledge was recited before the play of “Ode to Joy” (欢乐颂)with recorders. This was not to express patriotism(爱国主义), or even to remember those who lost their lives on Sept. 11.

I feel I cannot support a nation that in this time of crisis looks outward for revenge(报复)instead of inward for peace. Perhaps we should think more about our problems.
