both开始的这句话如何理解?reflection on the great ideas of mankind over time provides是修饰什么的The latest congressional report acknowledges the critical importance of technical training,but also asserts that the study of the humanities (人文学科)and social sciences must remain central ponents of America’s educational system at all levels.Both are critical to producing citizens who can participate effectively in our democratic society,bee innovative（创新的)leaders,and benefit from the spiritual enrichment that the reflection on the great ideas of mankind over time provides.Both are critical to producing citizens这里为什么用doing（我知道这里是介词所以后面+doing,那be critical to do 也是有这个用法的吧?为什么不加to do 呢 英语

【答案】 producing citizens 应该是一个组合名词.查了一下可能是意思是社会中坚 社会栋梁的意思.
这个to表示对象而不是to do 的to.
and benefit from the spiritual enrichment that the reflection on the great ideas of mankind over time provides.
reflection后面这句话是修饰the spiritual enrichment 这个看that引导的从句是跟在谁后面的就可以了. 追问： 那我问下
像be easy to 后面可以加动名词吗

easy to cause, easy to make 后面实质是动词，容易造成
