-Please tell me how many times___ to the Summer Palace. -Only once. A have you gone B you have gone C have you been D you have been. 答案选C,为什么不选D?不是用陈述语序吗?
“中学英语语法”(外研社出版,海淀区教师进修学校编写”第425页 please explain to me why heavy objects and light objects fall at the same speed. 一样是陈述语气。 这种低级题目还需要大神才能解决,有点小瞧英语贴吧的智商了
