16．—When some students throw rubbish in our classroom, I feel ____. 

—____. It makes me want to tell them to clean up the classroom.

A. angry; So do I                                                   B. uncomfortable; Neither I do

C. anrily; So I do                                                    D. comfortable; Neither do I

第一个感觉生气，是情态动词。但是在回答的时候，feel却只能用do来替代。心里感觉是完全正确的。除了be做系动词的时候，其他的系动词都是要do的形式替代吗？
