Question

非谓语动词部分with so much work ( ) to be done,he looked very worried.
with so much work ( ) to be done,he looked very worried.（remain）
答案是remaining
为什么不是 to be remained

Answer 1

考查的是with结构用法.
1）语法分析：with + 宾语（O）+宾语补足语（Oc）
Oc如用动词充当,应该以被修饰的O为参照物,分析宾语和补足语的主被动关系.
2）宾语和宾补关系：到这里的分析需用到remain的用法：
此处remain 表剩下,为不及物动词,因此宾语和补语关系为：sth remain [to be done],宾语"work"和补语"remain"由此看出为主动关系.
3）分析时间特点.此处表“很多东西剩下有待于完成”,“剩下”是伴随的存在状态,“去完成”即“do” 这个动作才是将来的,所以用remaining 表示“当时剩下的”.
May the above be of help!
