Aka Purps is one of a group of endangered African penguins living at Mystic Aquarium. A few years ago, she got into a case of penguin-on-penguin violence and tore the flexor tendon (屈肌腱）in her ankle. Veterinarians (兽医）at the aquarium created a small molded plastic boot to stabilize and support her injured leg, but the boot was rather heavy and made walking awkward for the small penguin. It also needed to be replaced frequently, which was a time-consuming process, so they decided to look for a different approach.
Luckily, they knew just who to contact-their longtime partner Mystic Middle School, which had just gotten a 3D printer from ACT Group, a Connecticut-based partner of 3D Systems. The students at Mystic Middle School were thrilled to be asked to design a 3D printed boot for the penguin, though they were still new to the technology. Library Media Specialist Sue Prince contacted ACT Group for assistance. The company facilitated a workshop（车间）in 3D technology for the students, who used 3D Systems' Geomagic Capture 3D scanner to scan a cast of Purps' foot provided by the aquarium. They then imported the scan data into Geomagic Sculpt to add details to the boot, which they printed on a 3D Systems ProJet MJP 5500X multi-material 3D printer.
The 5500X allowed for the creation of a strong yet elastic (有弹性的）boot. It fit better than Purps' existing boot, and was also more durable; according to the penguin's caretakers, she immediately took off across the exam room as soon as they replaced her old, heavy boot with the new boot, walking more normally than she had in the five years since her injury.
The students learned a great deal about 3D printing and design, as well as how to take an idea from concept to reality ----something that will serve them well in the future. Perhaps a few future veterinarians, doctors and medical device developers will emerge from that classroom.
24. What can we learn about Purps from Paragraph 1?
A. She was unable to walk properly due to a fight.
B. She was injured by veterinarians' carelessness.
C. She enjoyed wearing her special plastic boot.
D. She was long abused by another group member.
25. What did ACT Group do for the students?
A. It adjusted their work schedules.
B. It helped them build a cast of Purps' foot.
C. It added details to their finished product.
D. It provided them with technical support.
26. How can we describe the new boot?
A. It is more lightweight.
B. It is a cure for Purps' injury.
C. It enables Purps to live in the wild.
D. It needs replacing every five years.
27. Where is the text most likely from?
A. A novel.
B. A guidebook
C. A newspaper.
D. A diary.

Garlic has surprising staying power. Twenty-four hours after eating the
stuff, a strong smell is still in the breath. In fact, one doesn't even need to put the garlic in one's mouth to get garlic breath. In 1936, A doctor wrote that soon after he delivered the baby of a mother with a very strong garlic odor (气味）to her breath, he noted that the child also had a strong garlic breath odor. "On occasion I have mentioned this to other men and they usually think that I am joking, " he wrote.
The reason garlic breath can happen to people who haven't even chewed the stuff themselves is that garlic contains sulfur compounds (硫化合物）that go into the bloodstream after being digested. Carried by the blood, they travel into the lungs and up the throat and out the mouth. No amount of brushing your teeth will get rid of it.
However, taming chemistry with chemistry, it turns out, is a better approach. Some years ago, Sheryl Barringer, a scientist at the Ohio State University, had a student ask her about doing a project on garlic breath. There was some research on foods that, if eaten alongside garlic, seemed to destroy the odor: some top performers included lettuce, celery, potato, parsley, mint, basil, apple and mushroom. But not as much was known about why. Barringer and some students since have looked to see just how well certain foods fight garlic breath and how, exactly, they do it.
The group's latest paper traces the odor-killing power to a likely chemical reaction between four of garlic's sulfur compounds and phenolics (酚类物质）。Lettuce, mint, and apple have been a focus. Of all the options, mint makes the most sense. Mint has very high levels of phenolics. Apple has a lower amount of phenolics, though still a good helping. But lettuce has the least of any substance tested, far less than even green tea, which has no odor-killing effect at all. "That's where I would say we don't completely understand what's going on, "says Barringer.
28. How might those people feel when hearing about the baby with garlic breath?
A. Embarrassed.
B. Surprised.
C. Worried.
D. Excited.
29. What might the underlined word "taming" in Paragraph 3 probably mean?
A. Fighting.
B. Producing.
C. Detecting.
D. Combining.
30. What had been found out before Barringer's research?
A. How garlic breath can be got rid of.
B. Why some foods can kill garlic breath.
C. How apples react to sulfur compounds.
D. Which foods can help remove garlic breath.
31. Which of the following has the lowest level of phenolics?
A. Mint.
B. Apple.
C. Lettuce.
D. Green tea.
D
After the season for giving, it is the one for throwing away. Each year in late December and early January a massive amount of plastic packaging is discarded (丢弃）worldwide. In Britain alone households generate 30%more waste, an extra 3m tonnes, in the month over Christmas. Most is destined for landfill. Lithuania will do less damage than many, though. The country now recycles at a record level. Almost three-quarters (74%) of plastic packaging waste was recycled there in 2017, the highest proportion in Europe.
Much of Lithuania's success is due to a deposit refund scheme (方案). Customers pay €0.10 extra when buying drinks containers. After use, these can be fed into reverse vending machines (反向自动售货机）installed in shops, which spit the deposit back out. The machines' contents are sent directly to recycling centres. By the end of 2017, 92% of all bottles and cans sold in Lithuania were
being returned. The overall plastic packaging recycling rate increased by almost 20%.
The Lithuanian government says the scheme has ignited a latent love for recycling in its citizens. Nearly 90%of Lithuanians have used the machines at least once. However, Lithuanians do not generally describe themselves as eco-fighters. A 2017 survey by the European Commission found they were less likely than most other Europeans to regard environmental issues as "very important".
The eagerness of Lithuanian recyclers may stem not from a love of the Earth but from a low net worth. A tenth of the population get by on less than €245 a month. In big cities it is common to see people scooping recyclable items out of bins to take to the machines.
Less litter and money for people who need it seems like a win-win. But it might not in fact be best for the environment in the long run. In Germany----where a similar, widely used refund deposit scheme has been in place since 2003---the earnings from keeping the deposits from unreturned bottles seem to have discouraged producers from switching to more sustainable packaging.
32. What might most Lithuanian customers do under the deposit refund scheme?
A. They send their drinks containers directly to recycling centres.
B. They spend more on drinks than other European customers.
C. They return their used drinks containers.
D. They use vending machines to buy drinks.
33. What did the 2017 survey find out?
A. Lithuania beat many countries in plastic recycling.
B. Lithuanians had low environmental awareness.
C. Lithuanians made much money from recycling.
D. Lithuania had an unequal income distribution.
34. What is the author's attitude to the deposit refund scheme?
A. Positive.
B. Unfavourable.
C. Ambiguous.
D. Uninterested.
35. What is the best title for the text?
A. Why Lithuanians cash in on their trash.
B. How waste turns into treasure in Lithuania
C. Who are recycling plastic bottles in Lithuania
D. Where Lithuanians throw away their plastic packaging

I wanted to say “no” until I looked down at their feet. They were wearing th in little sandals(凉鞋), wet with heavy snow. “Come in and I'll make you a cup of hot cocoa.” They walked over and sat down at the table. Their wet sandals left marks upon the floor. I served them cocoa and bread to fight against the cold outside. Then I went back to the kitchen and started cooking. The silence in the front room struck me. I looked in. The girl held the empty cup in her hands, looking at it. The boy asked in a flat voice, “Lady, are you rich？” “Am I rich? Pity, no！” I looked at my worn-out slipcovers(椅套). The girl put her cup back in its saucer(茶碟)carefully and said, “Your cups match your saucers.” They left after that, holding their papers against the wind. They had reminded me that I had so much for which to be grateful. Plain blue china cups and saucers were only worth five pence. But they matched. I tasted the potatoes and stirred(搅动)the meat soup. Potatoes and brown meat soup, a roof over our heads, my man with a regular job, these matched, too. I moved the chairs back from the fire and cleaned the living room. The muddy marks of little sandals were still wet upon my floor. Let them be for a while, I thought, just in case I should begin to forget how rich I am. 36．Which of the following would be the best title for the text? A．Lady, are you rich? B．A story of Thanksgiving Day C．Don't forget how rich you are D．Does cups and saucers match well? 37．Which of the following statements is NOT true according to the passage? A．The girl thought the writer was rich just because she wanted to make the writer happy. B．The writer had thought she wasn't rich because her supplies were not expensive. C．If cups and saucers match well, they are a best pair even though cheap.
