Feel free to ask me anything on todays Great Wall tour.在今天的长城游中，大家尽管问我任何问题，不要拘束。feel free是英语口语中一个常用表达。若有人让你feel free to do something, 就是让你无需束，只管按照自己的意愿去做某事。例如：A: Can I use your bathroom? 我可以用一下你的卫生间吗？B: Yes, feel free. 可以，请随意。As far as I know, there are no man-made objects as big as this. 据我所知，再没有像它这样大的人造物体了。as far as I know是一个固定的表达方式，意思是“据我所知”,相当于so far as I know。Eg:As far as I know, Jacks got twin sisters. 就我所知，杰克有一对孪生姐妹。3) Role-play the conversation.V.
