Question

（A surplus） （allows）（ snow）（ to accumulate ）and （for the pressure of snow accumulated over the years )to (transform buried snow into glacial ice with a depth great enough for the ice to flow.)
我自己做了句子划分,我搞不懂的是 后面的 （for the pressure of snow accumulated over the years )to (transform buried snow into glacial ice with a depth great enough for the ice to flow.)
请问 有没有 allow for sb to do sth 这样的句式?

Answer 1

简化成：A surplus allows snow to accumulate and to transform.这句话的谓语动词是allow.连接两个动词不定式to do,表示并列的关系.for the pressure of snow accumulated over the years 介词短语,做原因状语没有a...
