S: 当我们到了看起来像一个大集市的地方, 我迷路了, 因为人们从四面八方飞来飞去。 What looked like a large market在句中作reach宾语。 T: I agree with you.Here“what looked like a large market”is used as an object.For example, Work hard and you will be able to obtain what you are expecting one day.Let’s make some sentences belonging to object clauses with“what”. S: Do what I asked you to. S: They reached what they thought they had been dreaming of. S: What we haven’t got seems much better than what we have got. T: Wonderful sentences.“in all directions”is“从四面八方”in Chinese.For example, Hearing the noise, all birds on the trees flew in all directions.Then how to understand“because of the people flying in all directions? S: Because of + something/doing something. T: Right.There is some difference between“because”and“because of”.As a result, because of the people flying in all directions = because the people were flying in all directions.

S: The room is comfortable to live in. S: English is difficult to learn well. S: In fact, English is not as hard to learn well as you thought. T: Excellent.
