Dear Tony,
The customs in our country are very different from yours. If you want to visit a frieng's house,you should knock at the door first. After you come into the room,you would not sit down until the host asks you to take a seat. And it's rude to ask about how much the things are. Another thing is that it is very rude to say you're full. If you don't want any more food,you should just say,"It was delicious." I have to say it difficult for you to remember everything,but I believe you're gradually getting used to things. Hope you're having a good trip.
Yours
第三个应该是how much 吧 我想问的是屋内的东西多少钱
第四个不是it's+形容词 for sb. to do sth.的用法吗,我记得这个句型在动词后is要省略的吧
嘿嘿
And it's rude to ask about how much the things are变成And it's rude to ask about the price of any thing in the house
第四个我觉得还是加了会好点
