談及插入語從句在這裡就會自然的提出兩個問題。第一，間隔的位置一般位於什麼哪裡？第二，插入語一般由什麼東西構成？
在文章中看得最多的情況就是
1) 主謂分隔：Rose, a young American poet, is brilliant. (被同位語隔開)
Susan, I suppose, finds the right way to go.(被插入語隔開)
2) 複合謂語分隔：You might at least offer to help. (被狀語隔開)
3) 動賓分隔：They estimated in the newspaper the costs of health care.(被狀語隔開)
4) 固定搭配分隔：They thought in a systematic way about the problems.(被狀語隔開)
5) 連詞與後續部分分隔
在考研真題中這種情況非常多。比如，What is hard to establish is whether the productivity revolution that the business assume they are presiding over is for real.中they are presiding over 就是一個主謂結構的插入語，隔開了主謂部分。
另外，這種情況在翻譯真題出的頻率也很高：Whorf came to believe in a sort of linguistic determinism which, in its strongest form, states that language imprisons the mind.在這裡in its strongest form這個介詞短語講定於從句的引導詞與定從隔開了。
到底什麼東西做插入語呢？
首先要說明一點就是插入語的成分問題，它是一個對句子的內容補充、添加、限制或者解釋說明，並不是句子的獨立語法成分，在閱讀時可以跳讀來把握句子整體結構。
一般說來由以下三個層面來做插入語：
第一從詞的層面。比如副詞：consequently, however,等。This view, however, seems to be wrong.
第二個層面短語。如不定式短語to tell you the truth, to be frank等，或者for example也是
Mr. McWhorter’s academic specialty is language history and change, he sees the gradual disappear of “whom”, for example, to be natural……這個地方for example 所處的位置阻礙了同學們對於這個賓語和賓補的理解，增加了該句的難度，而這一點往往是考研的重點。
第三個層面句子層面。比如as we know it, what we call it
He is what we call it a walking dictionary.
