时文阅读与练习29 My VR experiences 我的VR体验之旅 1 My first impression of VR was not that good after my first attempt lasted about 60 minutes. At the end of that time, I decided that it wasn't for me and I sold my headset for more than I paid for it. 2 That was a few years ago and the headset I used was the PSVR. Yes, I could have gone for one of the more advanced headsets but, at the time, my PC wasn't up to it. I thought that a quick win with a PSVR could satisfy my curiosity (好奇心), but I was wrong. 3 In 2019, with the appearance of a lot of new headsets, I decided that, maybe, it was time to try VR again. I chose to use the Big screen app to watch movies to feel as if I were at the cinema. What was interesting for me was to see what the actual quality was like but, importantly, what kind of experience you could have. Yes, for someone who doesn't always like the movie-going experience, this could have turned out to be the best of both worlds. I didn't have to spend money on expensive snacks (小吃) and parking and I didn't have to put up with bad smells. 4 I have to say that the whole VR experience has improved quite a lot. Yes, things have improved, but it's not perfect. In fact, I don't think we've reached the “good enough” stage (阶段) yet. 5 As for other VR apps, I once told a well-known editor that VR was promising. He just looked at me with a look that said, “It is never goanna happen.” Well, the time has come, and you can actually do this now. 6 VR isn't for everyone, I understand, but it can be a choice for some. I'd like to think that the next generation of headsets will improve some of the problems that we're still seeing. Reading Check Choose the best answers according to the text. 1.

To animal experts, they have been a mystery for a very long time. Now, researchers say they have uncovered how the wombat creates their unusually-shaped excrement(粪便). 2 Researchers at Georgia Institute of Technology first started studying the wombat's ability to poop cubes back in 2018. They compared their intestines(肠) to those of pigs. They inserted a balloon into the animals' digestive tracts to see how they stretched to fit the balloon and found regions of varied thickness and stiffness. 3 Scientists then created a 2D mathematical model to copy how these intestine regions contract and expand with the rhythms of digestion, shaping the poop into its cuboid shape. Softer intestinal regions squeeze slowly and mold (塑造) the final corners of the cube over multiple days. Interestingly, in most mammals, the contractions (收缩) of intestinal muscles occur in all directions, but in wombats, the grooved (有沟的;有槽的) tissue and irregular contractions shape the poop differently. 4 While this research may seem completely meaningless, or just meant to satisfy human curiosity, the scientists involved in the study say that these new findings could have a big impact on human digestive health research and manufacturing technology. It would be a cool method to apply to the manufacturing process, how to make a cube with soft tissue instead of just molding it. 5 Now that the mystery of how wombats produce cuboid poop seems to have been solved, that only leaves the “why”. Scientists have some theories about this as well. One states that because wombats pick up their poop and pile it as a way of communicating between them, the cuboid shape helps them build higher poop towers. 6 Another theory claims that because wombats tend to use their poop to mark their controlled land on rocks and logs, the cuboid shape of the excrement ensures that it won't simply roll off. Reading Check Choose the best answers according to the text. 1. What makes wombats' excrement so particular? A. Its shape. B. Its smell. C. Its hardness. D. Its ingredient. 2. How did the scientists start the research in 2018? A. By analyzing data. B. By studying examples. C. By recording activities. D. By making comparison. 3. What can be inferred according to paragraph 3? A. A 2D mathematical model was applied in the research. B. The poop was into its cuboid shape within several hours. C. The intestinal muscles of wombats contract in all directions. D. Detailed formation of cuboid poop was recorded in the research. 4.

While this research may seem completely meaningless, or just meant to satisfy human curiosity, the scientists involved in the study say that these new findings could have a big impact on human digestive health research and manufacturing technology. 尽管这项研究似乎毫无意义,或者只是为了满足人们的好奇心,但参与研究的科学家们说这些新的发现可能会对人类消化健康的研究和制造技术有很大的影响。 【点石成金】句中While引导的是一个让步状语从句,意为“尽管”;the scientists involved...manufacturing technology为主句部分。involved in the study相当于who were involved in the study,为过去分词短语作后置定语;that引导的是一个宾语从句。 Flat pasta that changes shape 可变形的意面 1 If you're a pasta (意大利面) lover, then you know that the noodles come in all sorts of different shapes. There are flat noodles, round noodles, shells, fancy spirals, and many more. Some of these pastas, like ordinary spaghetti, pack easily into a small box or package. But others require much larger boxes because their hard 3D shapes wrap around a whole lot of air. 2 Now a team of scientists at Carnegie Mellon University (CMU) has figured out a way to deal with the problem. The team of scientists have developed an unusual way of making flat pasta that allows it to turn into fancy 3D shapes as it cooks. 3 Lining Yao, who leads the “Morphing Matter Lab” at CMU, says the team got the idea of 3D pasta from “flat-pack furniture”. Flat-pack furniture, such as that sold by IKEA, comes tightly packed in a box, but then can be built into a large piece of furniture that takes up a much greater amount of space. 4 To bring the flat-pack idea to the pasta world, the scientists used a fairly simple trick—stamping grooves (凹槽) in the pasta. “The groove side expands less than the smooth side, leading the pasta to change into shape,” explains one of the researchers. 5 But knowing what kinds of grooves to make and where to make them is the trick. By figuring out just the right spots for grooves, the researchers were able to control the final shape of the pasta. The scientists used computers to help them plan their groove patterns. The team came up with lots of different shapes. The pasta looks, feels, and tastes just like ordinary pasta once it is cooked. 6 The team hopes their new method will help the environment in two ways. Like flat-pack furniture, it should take up less space when it's being transported. The pasta should also require much less packaging, meaning far less plastic waste.
