跟楼上的说得一样,be lost in thought是陷入沉思的意思
没有losting. losing是动名词,但是不能形容什么东西
lost的其中一个用法就是:
giving so much attention to what you are doing that you are not aware of anything else that is happening around you
比如:Ann was completely lost in her book.
跟lost in thought一样,可以lost in books, lost in the song........
但是就不能用losing本回答被提问者采纳
