单选题 "I don't understand how you got a ticket. I always thought you were a careful driver." "______, but I thought I could get through the intersection before the light turned."
A. I am usually B. Usually am I
C. I usually am D. Am I usually

【正确答案】 C

【答案解析】[解析] I usually am是省略句，完整的句子应当是I am usually a careful driver。usually修饰表语时通常要放在be动词之后的表语之前，但在省略了表语的省略句中要放在be的前面，在说话时要重读。
