VOA 《Pandemic Helper ? Techonology Succeeds, Falls Short During the Crisis》
Such efforts were stymied by a lack of central coordination among governments.
A lack of understanding in tech circle of who makes decisions at the local level and how best to reach them, Ries said.
There was nobody to interface with.
不懂这里的of who ? 这里的of who 如何分析?of含义是什么?
你断句错误。an understanding of sth。语法上of介词短语作定语修饰名词understanding. 语义上,of表示动宾关系,of的宾语是understanding作动词时的宾语。of的宾语可以是名词词组,也可以是wh-名词性从句。你的句子中 who makes decisions at the local level and how best to reach them 分别为名词性疑问分句和名词性wh-词+不定式作介词of的宾语。即who和介词没有直接关系,而是who从句和how-不定式短语作介词of的宾语。你应该反思你的阅读习惯。
