题目
In my everyday life, I am on an ongoing journey to figure out different ways to reduce my carbon footprint on the planet. A carbon footprint is the measure of influence our activities have on the environment, in particular climate change. It is calculated by the amount of greenhouse gas we produce in our daily lives. Fortunately, nowadays it is much easier to make eco-friendly lifestyle choices than, let's say, 20 years ago. But one question has been on my mind a lot lately: is it better to buy new eco-friendly products or used traditionally produced goods?
After doing some research, I have decided that some things are better new and others are better used. Let me try to explain.
A carbon footprint is made up of two parts, the primary footprint and the secondary footprint. The primary footprint is a measure of our direct emissions（排放）of carbon dioxide（CO2）from the burning of fuels, including household energy consumption and transportation. The secondary footprint is a measure of the indirect CO2 emissions from the whole lifecycle of products we use-those related to their production and breakdown.
Based on this understanding, we have a good deal of control and responsibility over our carbon footprint. Things like dishes, clothes and furniture fall into the “secondary footprint” group, so less is more and we can focus on finding used goods to avoid the added production. However, for the car and the other appliances（设备）that we need we can go with new, energy-saving models. I heard somewhere that electronics and appliances give off 90% of their carbon footprint after they leave the factory. So it seems most reasonable to go for the energy-saving models. The main concern here is the amount of energy that goes into the making of new products and whether or not that extra carbon is worth the footprint the product will make once it gets to you.
24. What is the text mainly about? （ ）
A. What appliances to buy to save energy.
B. What a carbon footprint means in our life.
C. How to identify different carbon footprints.
D. How to make eco-friendly lifestyle choices.
25. What do we know about the secondary carbon footprint? （ ）
A. It is related to our consumption of fuels.
B. It is made when we are buying the products.
C. It is less harmful than the primary carbon footprint.
D. It is counted as ours though not directly made by us.
26. Which of the following helps reduce our carbon footprint according to the author?（ ）
A. Using second-hand textbooks. B. Using old and expensive cars.
C. Buying new but cheap clothes. D. Buying new wooden furniture.
27. "The footprint" underlined in the last sentence refers to the CO2 produced in ________（ ）
A. using the product B. recycling the product
C. making the product D. transporting the product

In my everyday life, I am on an ongoing journey to figure out different ways to reduce my carbon footprint on the planet. A carbon footprint is the measure of influence our activities have on the environment, in particular climate change. It is calculated by the amount of greenhouse gas we produce in our daily lives. Fortunately, nowadays it is much easier to make eco-friendly lifestyle choices than, let's say, 20 years ago. But one question has been on my mind a lot lately: is it better to buy new eco-friendly products or used traditionally produced goods?
Para. 1: 主题句：... is it better to buy 联考事业单位b类都考什么 new eco-friendly products or used traditionally produced goods?
A carbon footprint is...说明这是下定义，判断本文是概念介绍说明文，这类文章一定要理解定义，否则后面返工耽误时间。
功能词：
1. in particular climate change
2. Fortunately, nowadays it is much easier to make eco-friendly lifestyle choices
3. one question...: is it better to buy new eco-friendly products or used traditionally produced goods?
脑子里迅速确定 A carbon footprint的定义的核心，以及主题：
... is it better 联考事业单位b类都考什么 to buy new eco-friendly products or used traditionally produced goods?
如果抓住了概念文的特点，那么第一题就容易了：
24. What is the text mainly about? （ ）
A. What appliances to buy to save energy.
B. What a carbon footprint means in our life.
C. How to identify different carbon footprints.
D. How to make eco-friendly lifestyle choices.
只有D项：如何做出环保生活方式的选择，和末句：是买环保新产品
After doing some research, I have decided that some things are better new and others are better used. Let me try to explain.
Para. 2: 回答第一段的问题：some things are better new and others are better used.
A carbon footprint is made up of two parts, the primary footprint and the secondary footprint. The primary footprint is a measure of our direct emissions（排放）of carbon dioxide（CO2）from the burning of fuels, including household energy consumption and transportation. The secondary footprint is a measure of the indirect CO2 emissions from the whole lifecycle of products we use-those related to their production and breakdown.
Para. 3: 主题句：A carbon footprint is made up of two parts, the primary footprint and the secondary footprint.
本段是具体阐述概念的内涵，作者分成两类，那么就要关注两个类别的异同，尤其是不同的地方。
The primary footprint：
direct emissions
the burning of fuels, including household energy consumption and transportation
The secondary footprint：
the indirect CO2 emissions we use
the whole lifecycle of products…production and breakdown
25. What do we know about the secondary carbon footprint? （ ）
A. It is related to our consumption of fuels.
B. It is made when we are buying the products.
C. It is less harmful than the primary carbon footprint.
D. It is counted as ours though not directly made by us.
这道题问的是The secondary footprinted 的特点，请对照表格里的，属于细节题：
It is counted as ours = we use; not directly made by us = indirect CO2 emissions
干扰项是B，命题人利用buy来混淆use。
Based on this understanding, we have a good deal of control and responsibility over our carbon footprint. Things like dishes, clothes and furniture fall into the “secondary footprint” group, so less is more and we can focus on finding used goods to avoid the added production. However, for the car and the other appliances（设备）that we need we can go with new, energy-saving models. I heard somewhere that electronics and appliances give off 90% of their carbon footprint after they leave the factory. So it seems most reasonable to go for the energy-saving models. The main concern here is the amount of energy that goes into the making of new products and whether or not that extra carbon is worth the footprint the product will make once it gets to you.
这一段主题句：we have a good deal of control and responsibility over our carbon footprint.
主要是总结，照应首段，说明我们要控制好我们的carbon footprint。
However是个mark word，前面说的是focus on finding used goods，后面说的是we can go with new, energy-saving models。最后一句是总结：最主要的问题是，我们投入在制造新产品的能量和生产产品时所产生的额外的碳是不是值得产品带来的碳足迹？（这是字面直译，可以这样理解：打个比方，假如碳足迹总数为100，相同功能的新产品碳足迹可能只有60，在出厂后减去生产中的10%只有54的释放量了；那么生产中的碳足迹数量6（就是末句里的extra carbon）加上生产过程中的投入的能量和新产品使用中的碳足迹（54）比起来是不是值得？
关键还是that extra carbon的理解，因为that的限制，所指不大可能太远，靠近原则就是指the making of new products过程中的。这题直接决定了27题答案A。
26. Which of the following helps reduce our carbon footprint according to the author? （ ）
A. Using second-hand textbooks. B. Using old and expensive cars.
C. Buying new but cheap clothes. D. Buying new wooden furniture.
这道题同样利用can focus on finding used goods to avoid the added production. 和it seems most reasonable to go for the energy-saving models.两句，对比，只有A项符合。
27. "The footprint" underlined in the last sentence refers to the CO2 produced in _________. （ ）
A. using the product B. recycling the product
C. making the product D. transporting the product
