We recently carried out a survey of local residents, and their responses were interesting. People were very concerned about the lack of visibility on some roads due to cars parked along the sides of the roads. We'd expected complaints about the congestion near the school when parents are dropping off their children or picking them up, but this wasn't top of the list, and nor were noise and fumes from trucks and lorries, though they were mentioned by some people.
这段话中，结合考点，我们知道very concerned 是意在强调，因此后面concern的内容是我们要听的重点，是核心，对应选项再找出同等表达选项即可。而后面的we’d expected.....跟出的内容并不是核心，因为它是一个常见句型，表达“本以为......而实际则是相反的”，后面随之而来的‘but’也再次验证了这一点，那么也就是无关父母接送孩子的事，此选项为陷阱项；nor 则是难点，否定词引领的倒装，也就是否定词的作用，所以也与trucks and lorries 无关。
