常用来修饰延续性动作。
7. Wildfire smoke, on the other hand, is everywhere.
解析:on the other hand 是转折连接短语,意为"另一方面",用来和前文提到的"营火烟雾"的情况形成对比。这个短语在句中作插入语,前后用逗号隔开,不影响句子的主干结构。everywhere 是地点副词,在句中作表语,意为"无处不在"。
8. Both Kovesi and Hughes agree that the best thing for kids to do is to stay inside when wildfire smoke is in the air.
解析:both... and...是并列连词,意为"两者都",用来连接两个并列的主语 Kovesi 和 Hughes,谓语动词用复数形式 agree。that 引导宾语从句,作 agree 的宾语。the best thing for sb to do is to do sth 是常用句型,意为"对某人来说最好的做法是做某事",前后都用动词不定式。when 引导时间状语从句,说明"待在室内"的条件。
9. Those activities require you to breathe harder and deeper, which gives you a greater exposure to the smoke and the particles the smoke carries.
解析:require sb to do sth 是固定搭配,意为"要求某人做某事",这里 require 后接宾语 you 和不定式 to breathe 作宾语补足语。harder and deeper 是副词比较级并列,修饰动词 breathe,意为"更急促;更深"。which 引导非限制性定语从句,指代前面
整个句子的内容,在从句中作主语。exposure to...是固定搭配,意为"暴露于……"。the smoke carries 是省略了关系代词 that/which 的定语从句,修饰 particles。
10. Kovesi said that masks can also help lower the risk a little, particularly N95 masks.
解析:that 引导宾语从句,作 said 的宾语,从句用陈述语序。help (to) do sth 是固定搭配,意为"帮助做某事",这里 to 可以省略,所以 help lower 是正确形式。a little 在这里作副词短语,意为"稍微;一点",用来修饰动词 lower。particularly 是副词,意为"尤其;特别",用来举例强调 N95 masks 这种类型的口罩。
