Fell 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。fell free是英语口语中一个常用表达。若有人让你feel free to do something, 就是让你无需拘束，只管按照自己的意愿去做某事。e.g. 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。2. As far as I know, there are no other 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。1) as far as I know是一个固定的表达方式，还可以说so far as I know, 意思是“据我所知”。e.g. As far as I know, Jacks got twin sisters. 就我所知，杰克有一对孪生姐妹。 Theyre not coming today, so far as I know. 他们今天不来了 就我所知是这样的。2) 句中man-made是一个合成形容词，意为“人造的”。像这样与-made复合而成的形容词不止一个。常见的有：handmade (手工制作的)、homemade(家庭制作的)、machine-made(机制的)、tailor-made(量体定制的；特制的；定做的)，用以描述产品的生产或制造手段，特点等，甚至还有像self-made (自学而成的；自我奋斗而成的；天然形成的)可以用来描述人。 e.g. We only sell homemade bread and cakes, and homemade wine. 我们只卖私家烘焙的面包、蛋糕、以及家酿葡萄酒。 The movie role was tailor-made for that actor. 这个电影角色是专为那为男演员量身设计的。Step 9 Homework1.
