【英语阅读】看不懂！求大神逐句翻译，详细解析！
The speaker, a teacher from a community college, addressed a sympathetic audience. Heads nodded in agreement when he said, "High school English teachers are not doing their jobs". He described the inadequacies of his students, all high school graduates who can use language only at a grade 9 level. I was unable to determine from his answers to my questions how this grade 9 level had been established.
My topic is not standards nor its decline. What the speaker was really saying is that he is no longer youngs he has been teaching for sixteen years, and is able to think and speak like a mature adult.
My point is that the frequent complaint of one generation about the one immediately following it is inevitable. It is also human nature to look for the reasons for our dissatisfaction. Before English became a school subject in the late nineteenth century, it was difficult to find the target of the blame for language deficiencies. But since then, English teachers have been under constant attack.
The complainers think they have hit upon an original idea. As their own command of the language improves, they notice that young people do not have this same ability. Unaware that their own ability has developed through the years, they assume the new generation of young people must be hopeless in this respect. To the eyes and ears of sensitive adults the language of the young always seems inadequate.
Since this concern about the decline and fall of the English language is not perceived as a generational phenomenon but rather as something new and peculiar to today's young people, it naturally follows that today's English teachers cannot be doing their jobs. Otherwise, young people would not commit offenses against the language.
我查到的第一句的翻译是：演讲人是社区大学的一名老师，他的发言引起了观众的共鸣。
但是原文The speaker, a teacher from a community college, addressed a sympathetic audience. 中的addressed a sympathetic audience最么会翻译成“引起了观众的共鸣”呢？
