Question

—Mr. Ling，I have some difficulty ________ the article.

—Remember ________ it three or four times at least.

A.to understand；reading

B.understanding；reading

C.understanding；to read

D.to understand；to read

Answer

C

【解析】

句意：——李先生，我理解这篇文章有些困难。——记住至少读三到四遍。

考查动词形式。have some difficulty（problem）doing sth.是固定表达，意思是“做某事有困难”，可知第一个空填understanding；remember doing sth.记得做过某事（已做）；remember to do sth.记得去做某事（未做），根据句意和语境可知“记得去做某事（未做）”，填to read，故选C。
