once we really communicated our wish to understand where people are atand help, the response has been really strong.
我的语感第一感觉那个at是多余的，但仔细剖析也看不出问题，系词are接介词at，where作at的介宾。请问at在这里到底什么使用方法？能否去掉？
once we reallycommunicated our wish to understand where people are at and help, theresponse has been really strong.
1. 动词不定式 to understand where people are at and help，作 wish 的定语，understand 与 help 并列。
2. where 作介词宾语不是问题，所以，这里用 at 没语法错误。
3. where 除去表示“地址”外，还可以引申为“处境；境况”，此时与 at 搭配，表示大家所处的社会地位、身份、生活情况等含义。假如没 at，那就是纯粹的地址定义。
4. 不定式的意思是：知道大家处于哪种生活状况并提供帮助。
