单选题
Although he is recognized as one of the most brilliant scientists in his field, Professor Jefferson cannot seem to make his ideas understood in class.
【正确答案】
D
【答案解析】画线词make his ideas understood使他的想法被人理解。其含义等于：get his ideas across，即“使他的想法被人理解。”故答案为D。本题题意是：虽然他被认为是这一科学领域最卓越的科学家，但杰弗逊教授很难使自己的想法为班上学生所理解。辨义：A．get his ideas down不是典型成语，大意是：把他的想法弄确实；B．summarize his ideas总结他的想法； C．recall his ideas回忆他的想法。
