2. Look these photos and practice the dialogue:
e.g. A: How high is Qomolangma?

Step 3 1a Match the facts you know:
Practice in pairs using the information in 1a.
Qomolangma | about 9,600,000 square kilometers in size |
The Sahara | 1,025 meters deep |
The Caspian Sea | 6,671 kilometers long |
The Nile | 8,844.43 meters high |
Step 4 Explaination:

2) Which is the most famous part of the Ming Great Wall?
Step 8 Language points and summary:
1. Fell free to ask me anything on today’s 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 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，还可以说so far as I know, 意思是“据我所知”。
e.g. As far as I know, Jack’s got twin sisters.
就我所知，杰克有一对孪生姐妹。
They’re not coming today, so far as I know.
他们今天不来了– 就我所知是这样的。
