二、阅读理解
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 cats of cutting down trees.
Secondly , products made from paper require 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 and 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 !
( ) 11. What does the underlined word “They” in Paragraph 2 refer to
Plastic products . B. Trees C. Paper products D. Business
( ) 12. Compared with transporting two million plastic bags , transporting two million paper bags requires _______ .
fewer trucks B. six more trucks

paper products are not a good choice for businesses
it is difficult for all businesses to turn to paper products
most people believe paper products are better than plastic ones.
