蚂蚁爬过公园，经过房子，穿过森林。不过，你说“经过”，我也可以明白意思。只是这样句子就没那么优美了。

zhè liàng chì chē shì lán sè de. tā bú shì hóng sè de. zhè liàng chì chē shì lán sè de. tā bú shì hóng sè. Both sentences are right.If you speak with a Chinese,both they can understand. tā bú shì hóng sè de.---->the tā stands for the car (che ) tā bú shì hóng sè .------->the ta stands for the color(se)

我的生日是(在)1月26日 adding or not are both right. If you add,when I hear it ()(我的生日是1月26日 ) from you,the point of this sentence is 生日 If you add 在，the listeners think your point is 1月26。 在 makes it a bit stress of the date. I will imagine maybe someone made your birthday wrong ,you strees it. But in fact,they are the same most of the time. Yes,the place is from the biggest to smallest,example:China-Guangdong-Guangzhou-area(district)---street NO Chinese think like this:First tell you my nationality,you will focus on that country first,Then tell you province,you move your mouse until you find the province.............--->then tell you the city,it is easy to find a city if you find out which province it is located. I guess so,not sure if it is right

ni (你)，while nin（您） both mean "you" but there is a heart = 心 in the character 您 So it is used in front of the old ppl or superior guys. In front of friends,we use 你

if you want to describe something,then the adjectives in english can be translated with 的 in Chinese."好看的" example,好（good OK）看（look） 的---》these 3 characters"好看的" combined an adj here.In chinese 好 can be a n,not adj sometimes.So it is easy to see 的 is useful and most used in Mandarin here :) I dont know if I am right,but i feel like this....my mother tongue is Mandarin

的 can be used as " somebody's"....I think in this case ,的 combines the subject or ppl ------>as a result being a pharase (adj. pharase).........我的 mine,你的 your，lily的，lily's,好的 fine，漂亮的beautiful，十分的very,大的 big，小的 small。all are representing adj. if translated in English here
