21、Starting in early January, 15-year-old Abby Gagne spent some weekends walking through snow in the 330 acres of woods around her house “tapping” trees. Abby’s family are sugar makers. For five generations, her family have collected sap from maple trees. They boil it down into the thick sweet syrup that North Americans love to apply on their pancakes.
Abby’s dad, Jason drills holes 1.5 inches deep into the trunks of maples in the woods. Sugar makers tap only older trees. These are usually at least 40 years old and 10 inches thick at chest height. They stick a tap into each hole, usually one per tree. Taps made of plastic are used for sap to flow through. They will come out at the end of the season, and the holes will return to health.
Plastic tubes hook up to the taps and connect them to one another. The sap flows into a collection tank in the woods. From the collection tank, the Gagnes pump the sap into a ma-chine to remove a lot of the sap’s water.Then it’s moved into an evaporator in a building called “sugar house”. The Gagnes make a fire out of maple wood chips. The fire heats the sap and boils it. When it reaches 219 degrees, the syrup is ready to be made.
Syrup is poured into glass or plastic bottles. But 150 years ago, sugar makers used tin cans. These containers could prevent syrup from seeping out and allowed them to ship it far from home and helped maple become a big business.
Sugar makers should thank native Americans for their knowledge. White settlers as early as 1600s learned the craft from the Ojibwe and other tribes. Early native techniques were similar to those sugar makers use now except that they collected sap in bark bowls before boiling it over an open fire. Either way, the resulting maple syrup was, and is tasty.

22、Most evenings, before watching late-night comedy or reading emails on his phone, Matt Nicoletti puts on a pair of orange-colored glasses that he bought for $8 on the Internet.
"My girlfriend thinks I look ridiculous in them," he said. But Mr.Nicoletti, a 30-year-old consultant in Denver, insists that the glasses, which can block certain wavelengths of light emitted by electronic screens, make it easier to sleep.
Studies have shown that such light, especially from the blue part of the spectrum (光谱),inhibits the body's production of melatonin(褪黑激素)，which helps people fall asleep. Options are growing for blocking blue light, though experts caution that few have been adequately tested for effectiveness and the best solution remains avoiding brightly lit electronics at night.
A Swiss study of 13 teenage boys, published in August in The Journal of Adolescent Health showed that when the boys wore orange-colored glasses, also known as 'blue blockers' and shown to prevent melatonin, in the evening for a week, they felt "significantly more sleepy" than when they wore clear glasses.The boys looked at their screens, as teenagers tend to do, for at least a few hours on average before going to bed, and were monitored in the lab.
Older adults may be less affected by blue light, experts say, but blue light remains a problem for most people, and an earlier study of 20 adults aged 18 to 68 found that those who wore orange-colored glasses for three hours before bed improved their sleep quality considerably relative to a control group that wore yellow-colored lenses, which blocked only ultraviolet(紫外线) light.
LEDs used in devices such as smart phones, tablets and televisions tend to emit more blue light than incandescent products（白炽产品). LEDs are also increasingly popular as room lights, but "warm white" bulbs, with less blue, tend to be a better choice than "cool white" for nighttime use. The lighting company Philips also makes a reduced-blue LED bulb, meant to be used before bedtime."In theory, anything that will decrease that blue light exposure at night will be helpful." said Christopher Colwell, a scientist at the UCLA, "I know some gainers who swear by those orange-colored glasses."
But orange glasses are not a panacea(万能药). Dr. Skene said."It isn't just getting rid of the blue and everything's fine," she said. The intensity of light, in addition to color, can affect sleep, she said, and not all brands of orange-colored glasses have undergone enough independent testing for their ability to aid sleep.
During the daytime, experts say, exposure to blue light is good. Best of all is sunlight, which contains many different wavelengths of light."That's what our brain knows," said Kenneth P.Wright Jr., director of the sleep and chronobiology(生物钟学) lab at the University of Colorado, Boulder.
A 2013 study he led, published in the journal Current Biology, showed just how different things can be without nighttime lights. After participants had camped in the mountains for a week, their bodies began to prepare for sleep about two hours earlier than normal.
Short of cutting out all evening electronics, experts say, it's advisable to use a small screen rather than a large one; dim the screen and keep it as far away from the eyes as possible; and reduce the amount of time spent reading the device.
"If you can look at the iPhone for 10 minutes rather than three hours, that makes a lot of difference," Dr.Skene said.
【1】What does the underlined word "inhibit" in Paragraph 3 probably mean?
A. prevent B. promote C. project D. process
【2】Which of the following statements is true?
A.The older a person is, the less he or she will be affected by blue light.

C.Traditional lighting companies are facing a dead end due to backward technology.
D.All brands of orange-colored glasses are not reliable for their ability to aid sleep.
【3】What are the contributing factors of a better night's sleep?
①Limited screen time before bed.
②A pair of color glasses.
③A small-sized screen of electronics.
④A place without nighttime lights.

A. ①②③ B. ③④⑤ C. ②③⑤ D. ①③④
【4】The purpose of this article is to ________.
A.advertise a brand of orange-colored glasses which can block blue light

23、 In Central America, sea turtle eggs are a popular cuisine dish. The eggs are hugely and secretly harvested onto tables, leaving the sea turtles listed as threatened. Yet we simply do not have the ability to continuously guard large beaches. Scientist Kim Williams was thinking hard when she had an “aha” moment: How about placing a fake(假的) egg containing a GPS tracker.
That’s how the special eggs come in. To build them:Williams and colleagues used a 3D printer. Then:they fixed in the smallest GPS tracking devices. As mother turtles laid their eggs under cover of night, the researchers slipped a single spy egg into each nest. Once they are covered in sand from the real ones: “it’s very difficult to tell the difference,” says Williams.
Of the 101 spy eggs, 25 were taken away while six of them were quickly discovered and left on the beach. The team received tracking data with the farthest egg travelling 137 kilometers inland and stopping at a local supermarket. The spy egg sent its final signal the next day from a personal house, suggesting that the research team had tracked the eggs all the way. The researchers stress that the tracker is not a way to catch local thieves: many of whom are living in poverty(贫穷), but rather a tool to better understand how the deal goes.
Still stopping stealing is not as simple as handing the tracking data over to the police. Across Central America, trade in sea turtle eggs can be legally ambiguous. In Costa Rica:for example, it is illegal to steal and sell sea turtle eggs but buying them is not a crime. It is not black and white. Meanwhile, local support is in need above all. “It but not tracking with eggs, is the real meat and potatoes of conservation,” says Williams.
【1】What is the major threat to the existence of sea turtles?
A.Unsafe GPS trackers. B.Unguarded Sea Beaches.
C.The popular dishes of sea turtles. D.The overhunt of turtle eggs.

24、For most people, the word “fashion” means “clothes”. But people may ask the question, “What clothes are in fashion?” And they use the adjective “fashionable” in the same way:
“She was wearing a fashionable coat. His shirt was really a fashionable colour.”
But of course there are fashions in many things, not only in clothes. There are fashions in holidays, in restaurants, in films and books. There are even fashions in school subjects, jobs…and in languages.
Fashions change as time goes. If you look at pictures of people or things from the past, you will see that fashions have always changed. A house of 1940 was different from one of 2021. A fashionable man in 1940 looked very different from his grandson in 2021.
Today fashions change very quickly. Some of this is natural. We hear about things much more quickly than in the past. Newspaper, telephones, television and the Internet send information from one country to another in a second.
New fashions mean that people will buy new things, so you see there is money in fashion.
