One day, however, while at a party, I heard an artist friend telling everybody that his idea came while he was having a shower. “What about you？” he asked. “Dont you get your creative thoughts from the same place？” “Im in and out in a hurry，” I told him proudly. “I have no time to waste！” “What a pity，” he said. “Thats the place where you need to slow down; plenty of great thoughts e from there！” I tried it out.I slowed down the whole process, started enjoying the warm water, taking a little longer to soap myself and even spending more time just enjoying the process, and realized how much I had missed in hurrying up all these years. A woman told me how much stress her friend was suffering from and how she sought to convince her that she needed to find ways to relax.She gave her a videotape on stress management and relaxation techniques, and encouraged her to watch it right away.Fifteen minutes later, her friend handed back the tape. “It was good，” she said, “but I dont need it.” “But its a 70minute video，” the woman replied. “You couldnt have watched the whole thing.” “Yes, I did，” her friend said. “I put it in fastforward！” A major social problem of the 21st century is Hurry Sickness.We hurry through work.We swallow fast food.We plain that we dont have enough time.We race through the days and weeks until one day we look back in amazement and ment, “Oh, how the years flew by！” Then we realize the heavy price we have paid for traveling fast.

But a new study published in Science Advances paints a more plex picture. While organic produce is likely slightly healthier to eat and, in some ways, more sustainable to grow, there are also downsides. Organic fruits and vegetables typically cost more than conventional ones. To get a certificate as organic, farmers must meet specific criteria, including growing produce without the use of genetic engineering and chemical inputs. Without these methods, the growing process typically requires more labor, time, and money, a cost that is passed down to consumers. Its true that in many ways, organic farming is more sustainable than conventional farming. But when it es to environmental concerns such as greenhouse gas output and water loss, the parison gets plex. Organic farms produce less greenhouse gas output per acre. However, because they are barred from using genetic engineering, pesticides (殺蟲劑), and other methods that increase efficiency (效率), organic farms also produce an estimated 19% to 25% less yield than conventional farms. While there isnt a whole lot of research on the topic, the few studies that do exist suggest greenhouse gas output and water loss might actually be higher on organic farms, on a per unit basis, says study author Verena Seufert. In addition, while organic produce is likely more nutritious than conventional fruits and vegetables, theres not a lot of evidence to support the claim that these often slight differences influence consumer health. The same is true for the pesticide remainder. In developed countries, where pesticide use is tightly regulated, theres no scientific consensus on how these often slight differences influence human health. Still, Seufert stresses that if you can afford to eat organic produce, you should do so. Organic farms provide safer work environments for workers, plus they support great biodiversity. The real takeaway from her study is not that organic produce is bad but that the practice needs more studies to increase the yield without lowering sustainability. But if you cant afford to buy organic produce, dont stress too much, particularly from a nutritional perspective. 語篇解讀：本文是一篇議論文，主要介紹了有機(jī)農(nóng)產(chǎn)品的一些情況。 8．What does the underlined word “downsides” in Paragraph 1 most probably mean? A．Dangers. B．Drawbacks. C．Benefits. D．Differences. 解析：選B　詞義猜測題。根據(jù)第一段最后一句可知，雖然有機(jī)農(nóng)產(chǎn)品可能稍微健康些，但在某些方面，也有其缺點(diǎn)。再結(jié)合語境和下文陳述的有機(jī)農(nóng)產(chǎn)品的缺點(diǎn)可以判斷，畫線詞應(yīng)指有機(jī)農(nóng)產(chǎn)品不好的一面，B項(xiàng)意為“缺點(diǎn)”，故B項(xiàng)正確。 9．Which key factor makes it hard to pare organic farming with conventional farming when it es to environmental concerns? A．The yield. B．The price. C．The water loss. D．The labor. 解析：選A　細(xì)節(jié)理解題。根據(jù)第三段第二句可知，當(dāng)涉及諸如溫室氣體排放和水資源損失等環(huán)境問題時(shí)，比較傳統(tǒng)農(nóng)業(yè)和有機(jī)農(nóng)業(yè)就困難了；且根據(jù)第三段的其他內(nèi)容可知，雖然有機(jī)農(nóng)業(yè)與傳統(tǒng)農(nóng)業(yè)相比更可持續(xù)，但因?yàn)椴荒苁褂没蚬こ碳夹g(shù)、殺蟲劑及其他提高效率的方法，有機(jī)農(nóng)業(yè)的產(chǎn)量相對低，故產(chǎn)量是使得兩者之間的比較變得困難的重要因素。A項(xiàng)意為“產(chǎn)量”，故A項(xiàng)正確。 10．Which of the following will the author most probably agree with? A．Farmers work environment should be improved. B．Organic produce should be made more efficiently. C．It isnt wise for consumers to buy organic products. D．The pesticide remainder do no harm to peoples health. 解析：選B　推理判斷題。根據(jù)第三段第四句可知，由于禁止使用基因工程技術(shù)和殺蟲劑等，有機(jī)農(nóng)場的產(chǎn)量估計(jì)會比傳統(tǒng)農(nóng)場的產(chǎn)量低19%至25%。據(jù)此可以判斷，應(yīng)當(dāng)提高有機(jī)農(nóng)業(yè)的生產(chǎn)效率，故B項(xiàng)正確。第五段的最后一句亦是提示。 11．In the authors opinion, why should we support organic produce? A．Its environmentally friendly. B．Its more nutritious. C．It helps keep the variety of plants. D．Its safer for consumers. 解析：選C　推理判斷題。根據(jù)第五段第二句可知，有機(jī)農(nóng)場為工人提供更安全的工作環(huán)境，而且有機(jī)農(nóng)場有助于保持生物的多樣性。據(jù)此可以判斷，我們應(yīng)當(dāng)提倡有機(jī)農(nóng)產(chǎn)品的原因之一是能保持生物的多樣性，故C項(xiàng)正確。 D (2019濟(jì)南模擬)Many people traveled to Las Vegas, Nevada during January 5th to 8th, 2017 for the 50th Consumer Electronics Show, or CES. The show is said to have the largest collection of new electronic devices in the world. The show had many examples of “smart home” devices. “Smart home” technology is designed to make life easier for people by letting puters control many things inside their homes. One such device actually begins working outside the home, when someone arrives and rings the doorbell. “When someone es to your front door and rings the doorbell, the light can turn on immediately. I get a notification when Im halfway around the world that someone came, and I can start talking to the person whos at my front door, and I can say, ‘Oh, here let me let you in.’ I can unlock the door for him very easily，” said Vivint, a smart home service provider. One electronics maker launched a device that lets people see and interact with their animals when they are away. The device, from Petcube, lets you remotely watch and talk to your pet through a personal device, according to a pany official. It can even give the pet a treat — if you approve and order it. For heating or cooling, there is a smart thermostat. This device can also send you a message if a big storm causes leaks or flooding. “Were trying to catch it with just a few drips before it bees a real big problem，” said Mike Sale of iDevices. A concern for many homeowners is the possibility that someone else might find a way to attack these smart home devices. An official from Vivint said his pany is sure that only owners of the home can gain use of information on the devices. Warren Katz from iDevices said his pany employs engineers from the defense industry to help prevent hacking. 語篇解讀：本文是一篇說明文。內(nèi)華達(dá)州的拉斯維加斯于2017年1月5日至8日舉辦了第50屆消費(fèi)類電子產(chǎn)品展覽會，其中的智能家居設(shè)備令人耳目一新。 12．What can be learned about the show?
