(Another student stands up to raise another question.)

S7:I don’t understand the structure:While unfinished,he was ugly…

T:The sentence “while unfinished” is equal to “while he was unfinished” reason why “he” and “was” can be omitted is that the subject in the while-clause and that in the main sentence are the same,and the while-clause contains a “be” verb,so in this case,the subject and “be” both can be conjunction like this includes:when,if,although,once,…Do you understand?
