解析

【分析】
首先通读全文理解主旨:本文介绍植物的多种作用。解题时需结合语法规则、固定搭配及语境逻辑逐个分析空格:
1. 第一空:考查固定搭配,millions of表示“数以百万计的”,需用million的复数形式;
2. 第二空:动词give后接人称代词宾格作宾语,we的宾格是us;
3. 第三空:前文讲植物的基础作用,后文转折讲更神奇的作用,需用转折连词But;
4. 第四空:much修饰形容词比较级,healthy的比较级为healthier;
5. 第五空:主语the air是不可数名词,一般现在时中动词用第三人称单数形式gets;
6. 第六空:主语plants对应可数名词hero的复数形式heroes;
7. 第七空:固定搭配breathe in表示“吸入”,需填介词in;
8. 第八空:特指前文提到的室内空气,用定冠词the;
