Question

if.,all we need to do is surgically sever your corpus callosum.
all we need to do is surgically sever your corpus callosum.是不是有两个动词啊.is 和 sever...如果对的话真正的动词是is 还是 sever啊

Answer 1

真正的动词是is,这句话实际上是一个省略句完整的是if., all we need to do is （to)surgically sever your corpus callosum,这实际上是一个固定句式,即to do后面可以省略介词.
