tocutdownairpollution，weshouldtakethebusorsubwayinsteadofdriving.……要想减少空气污染的话，我们应该乘坐公共汽车或者地铁，而不是开汽车。1.在句子的开头用todosth.的短语，并用逗号将其与句子主体部分隔开，相当于汉语“（若）要做……的话”。2.cutdown意为“减少，缩短，砍倒”。Weareconstantlybeingremindedtocutdownourfatintake.不断有人提醒我们要减少脂肪的摄入量。※拓展※有关cut的常用短语还有：cutup切开，切碎，抨击cutoff切除，切断，中断Cutupthecarrotsbeforeyouputthemintothepot.把胡萝卜切碎后再放入锅内。Theexileshadbeencutofffromallcontactwiththeirhomeland.流亡者被切断了与家乡的所有联系。学有所用
