选择题
—Dave, it’s dangerous to swim here. Look at the sign.
—Oh, I _______ it. Thank you.
A．didn't notice
B．won't notice
C．hadn't noticed
D．don't notice
答案
答案：A
题目分析：句意：大卫，在这游泳危险，看标志。哦，我没注意到，谢谢你。didn't notice一般过去时，won't notice 一般将来时，hadn't noticed过去完成时， don't notice一般现在时。根据语境可知是在这儿是因为之前没有注意到标志，为一般过去时，故选A.
