B(成都二模改编)(10 分)
对应教材：Unit 2 主旨大意：塑料袋和棉布袋
Is plastic always bad?
Cotton or plastic: 1.D Many of us would naturally say that the cotton bag is better, but that might only be true if you use that bag thousands of times. Surprised? Keep reading.
We all know that plastic is bad for the environment in many ways. Producing it can cause toxins(毒素) to be released(释放) into the environment. It’s used everywhere but often thrown away after a single use. 2.E Thrown-away plastic can lie in the ground for centuries or enter the sea causing harm to wildlife.
As a result, many people are looking for ways to reduce their plastic use. However, the picture is not straightforward(简单). 3.A It’s certainly more biodegradable(可生物降解的) than plastic. But the industrial production of cotton requires far more energy. As the bags are heavier, transporting them will lead to higher carbon emissions(碳排放). A report from Colum-bia University shows that cotton shopping bags need to be used over 7,000 times before they are more sustainable(可持续的) than plastic ones.
4.B Lightweight plastic parts in cars and planes help reduce fuel use(燃料使用) and emissions. If we didn’t use plas-tic in clothing and footwear, the amount of land, water and chemicals needed to produce enough natural materials would be very large.
Plastic lasts for centuries, but it also means it can be used to make things that can be reused again and again. 5.C So if we have to use them, then reuse them more, just for a bet-ter environment.

A.Let’s return to our cotton bag.
B.It’s not just about shopping bags.
C.The problem is that we often don’t.
D.Which kind of bag is better for the environment?
E.That means even more than needs to be produced.

答案： 1. D 【解析】根据“Many of us would naturally say that the cotton bag is better, but that might only be true if you use that bag thousands of times.”可知，此处在比较哪种材质更好，D项“哪种袋子对环境更好?”符合语境。故选D。
2. E 【解析】根据“It’s used everywhere but often thrown away after a single use.”可知，此处描述的塑料被广泛使用，因此应该需要很多塑料，E项“这意味着需要生产更多。”符合语境。故选E。
3. A 【解析】根据“It’s certainly more biodegradable than plastic. But the industrial production of cotton requires far more energy.”可知，此处在描述“棉布袋”，A项“让我们回到我们的棉布袋。”符合语境。故选A。
4. B 【解析】根据“Lightweight plastic parts in cars and planes help reduce fuel use and emissions.”可知，本段继续介绍相对于棉布袋来说，使用塑料的其他方面优点，B项“这不仅仅是购物袋的问题。”符合语境。故选B。
5. C 【解析】根据“Plastic lasts for centuries, but it also means it can be used to make things that can be reused again and again.”可知，此处解释虽然塑料可以制造反复使用的东西，但是仍然对环境有害，C项“问题是我们通常不会这样做。”符合语境。故选C。
