问题         Everything you do leaves a "carbon footprint" (碳足迹). For example, when you travel in a taxi, the car gives off CO2 into the air. CO2 is a greenhouse gas. Greenhouse gases make the earth become warm. To protect our environment, we need to leave less of a "carbon footprint". How big is your carbon footprint? To get an idea, take a look at the following numbers.
        Living areas
        TV sets and DVD players produce 723kg of CO2 a year.
        If you turn them off when you’re not using them, you can cut that number by 108kg.
        Laundry room (洗衣房)
        Drying clothes in a dryer produces a lot of CO2.
        If you use your dryer five times per week, you produce 185kg of CO2 per year.
        Dry your clothes in the sun instead.
        Bathroom
        If you take an eight-minute shower every day, you produce 616kg of CO2 a year.
        If you only use six minutes to take a shower, you can cut that number by 154kg a year.
If we spend less time taking a shower, we can cut the number of CO2.

选项 A、Ture
B、False

答案A

解析 less是little的比较级,对比文中由eight-minute shower到six-minute shower 的变化,可知题目正确。
