1.在第1句中，“公众”表达为the public，做主语时，谓语动词用单、复数都可以;作为一个整体，谓语动词用单数;强调每一个具体成员，谓讲动词用复数。“由于中国北方……”表原因，故处理成愿意状语从句，译作Since heavy smog stays continually in northern China, 地点状语“中国北方”置于句末。

2.第8句中的“……迫在眉睫”套用句it is extremely urgent to do...来表达。主语“治理空气污染”用不定式来表达目的，译作to control air pollution。

3.第4句中的“希望此举一方面能……，一方面能……”处理为主句“中国多个城市已经限制购车”(Many Chinesecities have imposed limits on car purchases)的伴随动作，用现在分词短语 hoping to ease... andmeanwhile control...来表达，使译文流畅、衔接紧密。

4.倒数第2句中的“来控制导致严重污染的行业”为目的状语，用动词不定式短语来表达to controlindustries...，其中定语“导致严重污染的”较长，故将其处理成定语从句，译作which cause heavypollution，置于被修饰语industries之后。
