题目

the examiner must have been pleased with my performance.he was pleased with my____
1 act 2 behaviour 3 efforts 4 doings
请问选择哪一个,及分别说出每一个为什么对与错

答案

efforts 的意思是"努力的结果,成就".
这一句要注意的是时态问题.前面是have been pleased ,表示已经完成的动作,后面是was pleased,选项中只有efforts才有"...的结果"的这一层意思.A,C,D的话都解释为行为,虽然与performance的意思比efforts更为接近.但考虑到时态,选efforts才合适
