请教英语高手一些新概念课本上问题
第25课第17~18行有句话：if you think what it must be like to share the deck of a ship with several squadrons of jet aircraft,.
请问这个句子的语法成分如何分析?it的作用?如果it是形式宾语那么它代替什么句子呢?the deck of a ship with several squadrons of jet aircraft是什么成分?
第28课15行有句话：.,carrying with in his pocket what remained of a bottle of medicine formerly prescribed for an indisposition of Mrs.Carlyle.
我想知道是否这里remained是做动词的,那么主语是what么,为什么remained 后边加of呢?remain不是及物动词么?
如果回答的详细能追加分的.

Answer 1

1、
it是代替动词不定式短语to share .,不是代替句子.
the deck .of jet aircraft在动词不定式短语中是to share 的宾语.
2、
carrying with 后面跟的是宾语从句,what是从句中的主语.
remain of 是动词短语
