题目

Governments around the world are pushing for an end to plastic straws ( 吸管 ) and bags. More and more businesses are turning to paper products as a choice. Paper is considered by many to be better than plastic. However, it, too, is harmful to the environment. Firstly, paper bags and straws are made from trees. Trees, as you know, can reduce ( 减少 ) carbon dioxide ( 二氧化碳 ) levels in the atmosphere. They can slow down climate ( 气候 ) change. An increase in the use of paper bags can cause more acts of cutting down trees. Secondly, products made from paper require more energy and water. About 10 percent more energy and four times as much water is used to produce a paper bag than a plastic one. You might say that we can use recycled paper to save that energy and water. This seems to be a good idea. However, it takes even more energy and water to go through the recycling process than to make a brand new paper bag. Products made from recycled paper are also often short-lived. Thirdly, paper products are heavier than plastic ones. That means they require more oil to transport. Seven trucks are needed to transport two million paper bags, while only one truck is needed to transport the same number of plastic bags. The increased weight also leads to a large amount of waste once the bags are thrown away. Paper products are actually a lose-lose for both the environment and businesses. They are more expensive than plastic products. A paper straw costs about 5 to 12 cents, while a plastic one usually costs only about 2 cents. The most environment-friendly solution is to avoid single-use products altogether. Products like glass water bottles and steel straws can be used over and over again. They are much better than either paper products or plastic products. Through increasing the use of these products, you can greatly reduce your throwaway waste and truly make our Earth a greener place! 1 ． What does the underlined word “ They ” in Paragraph 2 refer to? A ． Plastic products. B ． Trees. C ． Paper products. D ． Businesses. 2 ． Compared with transporting two million plastic bags, transporting two million paper bags requires ________. A ． fewer trucks B ． six more trucks C ． twice as many trucks D ． the same number of trucks 3 ． The writer compared the price of a paper straw and that of a plastic straw to show that ________. A ． paper products are not a good choice for businesses B ． it is difficult for all businesses to turn to paper products C ． most people believe paper products are better than plastic ones D ． paper products are as harmful to the environment as plastic ones 4 ． By writing this article, the writer mainly wanted to ________. ① compare plastic products with paper ones ② correct people’s wrong ideas about paper products ③ suggest people use reusable products like steel straws ④ list the advantages and disadvantages of using paper products A ． ①② B ． ③④ C ． ①④ D ． ②③ 答案： 1 ． B 2 ． B 3 ． A 4 ． D 【分析】 作者通过一些事实来证明纸制品并不是环保的，最环保的解决方案是完全避免使用一次性物品。 1. 代词指代题。根据 “Trees, as you know, can reduce carbon dioxide levels in the atmosphere. They can slow down climate change.” 可知此处讲树能减缓气候变化， “They” 指代上文出现过的 “trees” 。故选 B 。 2. 细节理解题。根据 “Seven trucks are needed to transport two million paper bags, while only one truck is needed to transport the same number of plastic bags.” 可知运送 200 万个纸袋需要 7 两卡车，而运送同样的塑料袋需要 1 辆卡车，相比之下运输 200 万个纸袋需要多用 6 辆卡车。故选 B 。 3. 细节理解题。根据 “Paper products are actually a lose-lose for both the environment and businesses. They are more expensive than plastic products. A paper straw costs about 5 to 12 cents, while a plastic one usually costs only about 2 cents.” 可知作者比较了纸质吸管和塑料吸管的价格，表明纸质产品不是企业的好选择。故选 A 。 4. 主旨大意题。通读全文可知，作者主要通过一些事实来证明纸制品并不是环保的，最环保的解决方案是完全避免使用一次性物品，写这篇文章主要是为了纠正人们对纸制品的错误观念并建议人们使用可重复使用的产品，如钢吸管。故选 D 。
