[A]
Plastic-Eating Worms
Humans produce more than 300 million tons of plastic every year. Almost half of that winds up in landfills (垃圾填埋场), and up to 12 million tons pollute the oceans. So far there is no effective way to get rid of it, but a new study suggests an answer may lie in the stomachs of some hungry worms.
Researchers in Spain and England recently found that the worms of the greater wax moth can break down polyethylene, which accounts for 40% of plastics. The team left 100 wax worms on a commercial polyethylene shopping bag for 12 hours, and the worms consumed and broke down about 92 milligrams, or almost 3% of it. To confirm that the worms' chewing alone was not responsible for the polyethylene breakdown, the researchers made some worms into paste (糊状物) and applied it to plastic films. 14 hours later the films had lost 13% of their mass — apparently broken down by enzymes (酶) from the worms' stomachs. Their findings were published in Current Biology in 2017.
Federica Bertocchini, co-author of the study, says the worms' ability to break down their everyday food — beeswax — also allows them to break down plastic. “Wax is a complex mixture, but the basic bond in polyethylene, the carbon-carbon bond, is there as well,” she explains. “The wax worm evolved a method or system to break this bond.”
Jennifer DeBruyn, a microbiologist at the University of Tennessee, who was not involved in the study, says it is not surprising that such worms can break down polyethylene. But compared with previous studies, she finds the speed of breaking down in this one exciting. The next step, DeBruyn says, will be to identify the cause of the breakdown. Is it an enzyme produced by the worm itself or by its gut microbes (肠道微生物)?
Bertocchini agrees and hopes her team's findings might one day help employ the enzyme to break down plastics in landfills. But she expects using the chemical in some kind of industrial process — not simply “millions of worms thrown on top of the plastic.”
1. It can be inferred from the last paragraph that the chemical might _____.
A. help to raise worms
B. help make plastic bags
C. be used to clean the oceans
D. be produced in factories in future

【分析】本文是一篇说明文。作者介绍了一项科学发现：一种吃塑料的虫子——大蜡螟，它胃中的酶能够降解塑料，从而为人们解决塑料污染问题提供了新的途径。
根据最后一段第二句But she expects using the chemical in some kind of industrial process — not simply “millions of worms thrown on top of the plastic”可知，研究人员期望不仅仅能用大蜡螟蠕虫去清理塑料垃圾，也期望在某种工业流程中用这种化学物质，故选D项。
[B]
When I was 17, I read a magazine article about a museum called the McNay, once the home of a watercolorist named Marian McNay. She had requested the community to turn it into a museum upon her death. On a sunny Saturday, Sally and I drove over to the museum. She asked, “Do you have the address?” “No, but I'll recognize it, there was a picture in the magazine.”
“Oh, stop. There it is!”
The museum was free. We entered, excited. A group of people sitting in the hall stopped talking and stared at us.
“May I help you?” a man asked. “No,” I said. “We're fine.” Tour guides got on my nerves. What if they talked a long time about a painting you weren't that interested in? Sally had gone upstairs. The people in the hall seemed very nosy (爱窥探的), keeping their eyes on me with curiosity. What was their problem? I saw some nice sculptures in one room. Suddenly I sensed a man standing behind me. “Where do you think you are?” he asked. I turned sharply. “The McNay Art Museum!” He smiled, shaking his head. “Sorry, the McNay is on New Braunfels Street.” “What's this place?” I asked, still confused. “Well, it's our home.” My heart jolted (震颤). I raced to the staircase and called out, “Sally! Come down immediately!”
“There's some really good stuff (艺术作品) up there.” She stepped down, looking confused. I pushed her toward the front door, waving at the family, saying, “Sorry, please forgive us, you have a really nice place.” Outside, when I told Sally what happened, she covered her mouth, laughing. She couldn't believe how long they let us look around without saying anything.
The real McNay was splendid, but we felt nervous the whole time we were there. Van Gogh, Picasso. This time, we stayed together, in case anything else unusual happened.
Thirty years later, a woman approached me in a public place. “Excuse me, did you ever enter a residence, long ago, thinking it was the McNay Museum?”
“Yes. But how do you know? We never told anyone.”
“That was my home. I was a teenager sitting in the hall. Before you came over, I never realized what a beautiful place I lived in. I never felt lucky before. You thought it was a museum. My feelings about my home changed after that. I've always wanted to thank you.”
2. What could we learn from the last paragraph?
A. People should have good taste to enjoy life.
B. People should spend more time with their family.
C. People tend to be blind to the beauty around them.
D. People tend to educate teenagers at a museum.

【分析】本文是一篇记叙文。作者讲述了自己误把一户人家当成博物馆且四处参观的奇特经历。
从最后一段中的Before you came over, I never realized what a beautiful place I lived in. I never felt lucky before可推知，人们往往会忽视自己周围事物的美，故选C项。
