1. to有"達到"的含意在, 句子是在講dirt達到多少高度, 用to a height of three to four feet 2. as high as的as有類比含意在, 表達和某個東西一樣高, B選項是說dirt和3~4英呎高dirt "一樣高", 這樣寫就像是說我和176公分的我一樣高, 這樣的寫法有redudency問題, 並不make sense --------------------------3、that无指代
that无指代
that 指代不清
that 没有正确的指代
that无指代
that无指代
补充,如果that 指代dirt,句子的意思就变成house as high as 3 feet dirt 一样高,不合逻辑,莫名其妙的引入了一个新东西3feet的dirt
that of 没有指代
that没有指代关系
that无所指
that没有指代对象
as high as that of, wordy and awkward
