求分析语法结构,many thanks
Nor does it help us with where we are going.
mostly from being the only child in a family
第一句,nor是否定词,位于句首,引起句子的部分倒装.
部分倒装是指将谓语的一部分如助动词或情态倒装至主语之前,即:助动词+主语+谓语(要用动词原形).如果句中的谓语没有助动词或情态动词,则需添加助动词do,does或did,并将其置于主语之前.
1) 句首为否定或半否定的词语,如no,not,never,seldom,little,hardly,at no time,in no way,not until… 等.
Never have I seen such a performance.
Nowhere will you find the answer to this question.
Not until the child fell asleep did the mother leave the room.
当Not until引出主从复合句,主句倒装,从句不倒装.
注意:如否定词不在句首不倒装.
I have never seen such a performance.
The mother didn't leave the room until the child fell asleep.
with后是一个where引导的宾语从句.
第二句being是动名词,用来做介词from的宾语,(ing也可能是现在分词,但是分词是不能做宾语的),in a family是介词结构做定语,用来修饰child.一般情况下如果是单个的词做定语一般放在名词前,比如:a good student,如果是一个短语作定语,通常放在名词后,称之为后置定语.
