Question

【題目】---Did you have any trouble catching the professor’s lecture?

---No. He spoke very slowly and clearly to make it easy _____.

A. to understandB. understand

C. understandingD. understood

Answer 1

【答案】A

【解析】

考查固定結(jié)構(gòu)。句意：——你聽教授的課有困難么？——不，他講得很慢且清楚以便讓人很容易理解。此處為形容詞+不定式作賓語補足語，表示“做某事是……的”，故A項正確。
