Cave exploration,or pot holing,as it has come to be known,is a relatively new sport.Perhaps it is the desire for solitude or the chance that they _______ an unexpected discovery that lures people down to the depths of the earth.
a) would make b) can make c) may make d) might have made
以上哪一個是最佳選項？具體講一講b項與c項的區(qū)別。謝謝！
管理員[admin]回復:
最佳答案就是 may make（當然也可用 might make），此處的 may (might) 表推測，符合此處的語境。雖然 can 也可以表推測，但它通常要用于否定句或疑問句。 回復時間:
