答案 16—20
[2026 安徽合肥期中]Think about what you like to wear at the weekend. There's a good chance that you like to put on a pair of blue jeans.
To make jeans feel nicer and give them a blue colour, some man-made chemicals are added to denim (牛仔布). Every time we wash our jeans, small bits (小块) of denim drop. Scientists studied the Great Lakes in America and found denim waste in them. The harmful chemicals in denim have spread far and wide. It's because they may mistake the bits of denim for food.
The answer was worrying: About 50,000 bits. Not all of them come into the environment. Wastewater treatment factories can deal with 99% of them. This may sound pretty good. However, the rest of them still have a bad influence on the environment.
Probably not. "We need to buy fewer jeans and only wash them when we truly need to do it," says Sam Athey, one of the scientists. Maybe you can wash your jeans less often or find new ways to recycle old jeans, so they don't harm the planet.
A. Does this mean we shouldn't wear jeans?
B. They might be putting some sea animals in danger.
C. Many people enjoy shopping for new jeans every season.
D. But according to a new study, our love for jeans may be bad for the earth.
E. Scientists also washed jeans to see how many bits of denim would drop each time.
F. They come out of our washing machine and into the world's rivers, lakes and oceans.

快速对答案
16—20 D F B E A
16. D 根据上文"There's a good chance that you like to put on a pair of blue jeans."及后文可知,此处承上启下,选项 D(但一项新研究表明,我们对牛仔裤的热爱可能对地球有害。)符合语境。故选 D 项。
17. F 根据上文"Every time we wash our jeans, small bits of denim drop."可知,选项 F(它们从我们的洗衣机中流出,进入世界上的河流、湖泊和海洋。)符合语境。故选 F 项。
18. B 根据下文"It's because they may mistake the bits of denim for food."可知,海洋动物可能误将碎屑当作食物,所以此处是指牛仔布碎屑会危害海洋动物,选项 B 符合语境。故选 B 项。
19. E 根据下文"The answer was worrying: About 50,000 bits."可知,选项 E(科学家还清洗牛仔裤,以观察每次会掉落多少块牛仔布碎屑。)符合语境。故选 E 项。
20. A 根据下文"Probably not. 'We need to buy fewer jeans and only wash them when we truly need to do it,' says Sam Athey, one of the scientists."可知,选项 A(这是否意味着我们不应该穿牛仔裤?)符合语境。故选 A 项。
