The enemy had no choice but ( )their arms and ( )

问题描述:

The enemy had no choice but ( )their arms and ( )
A,lie down ; give in B,lay down ; give in
C,to lay down ; give in D,to lie down ; to give in
为什么是选C呢,为什么用to,后面的为什么有不用to

have no choice but to是固定的用法,意思是“别无选择只得”,所以but之后要用to,and之后的动词是跟but之后的动词并列,故省掉to.
