Question

The teacher seldom let an opportunity to teach his students or to help them make up for the days of schooling they had missed ______.　

A. pass　　 B. passing　　 C. to pass　　　 D. being passed

 

Answer 1

A

let... pass 結(jié)構(gòu)，后面兩個(gè)動(dòng)詞不定式作opportunity的定語，而the days of schooling 有帶有定語從句they had missed。句意：這位老師很少錯(cuò)過教育學(xué)生幫助學(xué)生補(bǔ)課的時(shí)機(jī)。
