【題目】No one knows who salt, but it's very helpful to our life.

A. invented B. discovered C. created D. found out

【答案】B

【解析】句意:沒有人知道誰發(fā)現(xiàn)了鹽,但是它對我們的生活非常有用。invent發(fā)明,原來不存在,后來創(chuàng)造的;discover發(fā)現(xiàn),原來就存在;create創(chuàng)造,原來不存在;found out找到,查明,經過一番努力獲得了結果。結合句意,鹽原來就存在,因此表示發(fā)現(xiàn),故選B。
