1、同源高考阅读训练:史上最小飞行器诞生 等3那么2023届高考英语复习备考来自美国西北大学的一个研究团队,通过研究借风播散的种子,成功研发出迄今 为止最小的微型飞行器。Its raining microchips. One day, they could float gently through the air while gathering environmental data, land on the ground and then disappear when their work is done. That s the future a team of engineers sees fo
2、r what they/re calling “ micro flier”, a tiny winged microchip with designs inspired by nature.The accomplishment belongs to a team of scientists at the Northwestern University in Illinois, who developed the micro flier, a flying microchip that spins like a helicopter. This thing is the size of a gr
3、ain of sand but with small wings and an aerodynamic (流线型 的) design that allows it to fall in a controlled manner thanks to its barely visible propellers.How does that work? Well, the engineers used nature s “manual“ to get their inspiration for the micro flier, analyzing the behavior of various type
4、s of wind spread seeds. Instead of using a motor or engine, the tiny flying microchip uses the power of wind to catch a flight, spinning across the ground at a low speed. It is a stable flight, and the micro flier can stand in the air for a long time, which is why it could prove to be useful for a v
5、ariety of applications.While nature has designed seeds with very sophisticated aerodynamics, the Northwestern team claims its micro flier is better, as it is even smaller and its structure allows it to fall with more stable paths and at slower speeds than equivalent (相当的) seeds from plants or trees.
6、The engineers built the flying structure to be used for purposes such as population surveillance, pollution monitoring, disease tracking, to give just a few examples. And while this might look like a simple, limited device right now, researchers see its potential for becoming a highly functional ele

12、,飞行距离长达12, 000 千米。Every time you see a bird, there is a chance that you may be looking at the greatest marathon athlete in the world, particularly if you live in the US state of Alaska in late summer, and happen upon a bar tailed godwit (黑尾鹤).These little birds were recently found to travel 7, 500 m
13、iles (12, 000 kilometers) in a nonstop flight of 11 days from Alaska to the Firth of Thames near Auckland, New Zealand. Its not the longest migration ever一that title goes to the Arctic tern (燕鸥) which goes from the Arctic to the Antarctic along the west coast of North and South America or straight d
14、own the Atlantic every year for a total of around 14, 000 kilometers. However, it is the longest nonstop flight known to scientists.Unlike the tern, the godwit weighs a much heavier one fifth to four fifths of a pound, and relies on a muscular build much like a modern jet with narrow pointed wings a
15、nd a smooth body to reduce air drag. Despite these advantages which allow it to flap its wings nearly uninterruptedly for the entire journey, how can a small bird that lives for a few years navigate for days over nothing but empty ocean to arrive in New Zealand ?Some scientists have shown birds use
16、the sun as orientation, but there is also evidence of migration as a learned skillone study showing that adult raptors (猛) were better at course correcting for wind than juveniles, suggesting that experience comes into play. Another thought is that some birds may use electromagnetic sensory equipmen
17、t that allows them to see the magnetic field in a way that humans cannot.Even with the help of a magnetic compass, the record breaking bar tailed godwit, known as 4 BBRW, departed from Alaska and passed over the Aleutian Islands in a 224 hour flight without sleep over open ocean and with no land mar

No, wait. It would be better laser cooked, “ could be the kind of order you II hear in resta
24、urants a few years from now. The Digital Foods team at Columbia University finally found a way to prepare laboratory meat to make it more edible.Scientists have experimented with printed food since 2007. However, there was a big problem: they couldnt t find a way to cook it, since it doesnt t behave
25、 the same as traditional food. Until recently, they found that lasers would be the best substitute for pans when it comes to 3D printed meat. With this, it can have an appearance, taste and texture similar to natural meat foods.For this project, scientists first prepared a uchicken meat pure (果泥)“ w
26、ith real ground meat, which was used to model different shapes with a 3D printer. Then, they put the laboratory chicken samples under a laser that sent pulses of light to stir the meat and thus heat it. This cooking process took between 5 and 14 minutes. The results showed that the meat cooked with
27、a laser shrank 50% less and retained twice the moisture, that is, it was juicier. In addition, it released more flavor than those withother methods.In the study, researchers say that the secret of the seasoning is to emit laser pulses at different wave amplitudes. For example, a blue laser goes thro
28、ugh better to cook the inside of the meat, while the infrared laser works to brown the outside of the piece. After testing 3D laser chicken, researchers say it tastes better than traditional baked meat.While digital food seems more like science fiction, preparing food on a 3D printer is now a realit
29、y. Today this technology has progressed so much that it is possible to create various ingredients and dishes.The developers of this project hope that in the future anyone can have access to a 3D food printer and print any dish they want as if it were a kitchen recipe. One of the main obstacles is th
30、at there is no sustainable ecosystem behind it, so they consider a type of “Food CAD, a piece of software that is a combination of AutoCAD and Photoshop, as well as a kind of digital cookbook for this new future kitchen should be developed.Choose the best answers according to the textDetail 1. What was the initial problem with printed food?It couldnt t be cooked. B. Its taste might be poor.C. It wasnt t edible. D. It had no nutrients.Inference 2. What can we know about the chicken that was laser cooked ?A. It
