1、Maybe you want to know the difference between “Look at the map.”and“Read the map.”.
“look” is “看”,“read” is “读”,but the map is picture,so we use “看地图”to translate them. In EnglishI,I think use “look”is just have a look, useing“read”more seriou.they have different degree.
If you really want to distinguish them,Use “看一眼地图”to translate “Look at the map.”use “看地图”to translate “Read the map”.
In fact,sometime,we needn‘t to distinguish them."I'm reading",you can say:“我正在读书”or“我正在看书”.
2、“house” mean“房子,住宅”,间 is a partitive,“a house”mean“一间房子” .
(If my English have grammatical errors,please forgive me~ )
