27、产的产品，选择哪一种更好)”再根据第二段一整段的内容，作者通过研究得出答案，有时候是新型环保产品好，有时候是另一种更好。文章接下来的段落分析了作者这个答案是怎样找到的。由此可知，文章的内容主要是关于怎样选择更环保的生活方式的。故选D。6What do we know about the secondary carbon footprint?AIt is related to our consumption of fuels.BIt is made when we are buying the products.CIt is less harmful than the primary carbo
28、n footprint.DIt is counted as ours though not directly made by us.D推理判断题。根据第三段中“The secondary footprint is a measure of the indirect CO2 emissions from the whole lifecycle of products we usethose related to their production and breakdown.(第二种足迹是表示我们使用的产品在整个生命周期中间接排放的二氧化碳，这些是和他们的生产和排放有关的)”可知，第二种碳足迹虽然
29、不是我们直接产生的，但是也是我们使用的产品释放出来的，也是要归结到我们身上的。故选D。7Which of the following helps reduce our carbon footprint according to the author?AUsing secondhand textbooks.BUsing old and expensive cars.CBuying new but cheap clothes.DBuying new wooden furniture.A推理判断题。根据第四段中“Things like dishes, clothes and furniture fa

32、的能源以及这种额外的碳是否值得它到你手里以后，所产生的碳足迹)”可知，footprint在其后定语从句the product will make once it gets to you中充当make的宾语，意思是“这种碳足迹就是产品到你手里之后，你使用中所产生的”。由此推知，画线词组the footprint指的是“产品使用过程中产生的二氧化碳”。故选A。.阅读七选五Impolite cell phone users are anywhere where theres a cell phone signal. 1 .
