学员疑问：He explains his complex ideas from the starting point of visual illusions, which far from revealing how fragile our senses are show how remarkably robust they are at providing a picture of the world that serves a purpose to us. 老师这句话怎么理解？Which 引导的定从中动词是show吗？

老师解答：He（主语） explains（谓语） his complex ideas（宾语） from the starting point of visual illusions（状语）, which（引导定语从句修饰visual illusions，作从句的主语） far from revealing how fragile our senses are（定语从句的状语） show（定语从句的谓语） how remarkably robust they are at providing a picture of the world that serves a purpose to us（定语从句的宾语：how引导宾语从句）

句意：他先从视觉错觉解释了他的复杂观点，视觉错觉非但没有揭示我们的感官是多么脆弱，反而显示了它们在为我们提供一幅有目的的世界图景方面是多么强大。

点评分析：此句的难点在于far from revealing how fragile our senses are这个介词短语（包含how引导的宾语从句）做状语影响谓语动词的识别。
