问题
选择题
—How did you get in touch with Mrs.Green?
—Well，it seems to me that you've forgotten ________ me her telephone number the other day.
A．to tell
B．have told
C．telling
D．being told
答案
答案：C
根据问话人的句意可知，“已与Mrs.Green取得联系”了。故回答部分说明“已经忘记了告诉电话号码这件事”，应该使用forget doing sth/having done sth“某事已做，但忘了”，forget to do sth意为“忘记要去做的事情”，强调动作还未发生。
