Whether you use a GPS device（设备） in your car or Google Maps on your smartphone, few of us travel anymore without digital help. 1. For one thing, GPS isn’t as accurate as you might think. What’s more, science is beginning to discover that people who rely only on navigational technologies may have a poor sense of place during travel.
2. They soon become outdated as cities change, requiring users to continually purchase updated versions. They’re also easily damaged from exposure to water, poor weather conditions and other physical forces.
However, paper maps still offer a few advantages that technologies can’t. For example, studying a map allows you to get a full view of where you’re going, including the roads, forests, towns, historic sites, rivers and mountains you’ll come across along the way. Many older maps are wonderful, offering a lovely feast for the eyes. 3.
Research by Toru Ishikawa and colleagues at the University of Tokyo found that GPS users spent 30％ more time looking at their device than those who used a paper map. 4. Instead they tended to stare at their screens and follow directions, never gaining a full view of where they were going.
Therefore, go ahead and use your GPS, but also carry a paper map as a handy backup. 5. Also it could even be a life-saver!
A. It will improve your travel experiences.
B. But don’t hurry to fold up your paper maps.
C. They also had a poorer recollection of surrounding scenery.
D. Compared with digital maps, paper maps do have disadvantages.
E. What’s more, paper maps tend to focus on smaller geographic areas.
F. They can also take you back in time to have a glimpse（瞥） of history.
G. In other words, they didn’t see or experience much during their travels.
United States health officials are urging people to stop using electronic cigarettes, known as e-cigarettes. The call to action came after such products were linked to health problems. Five deaths have also been reported. E-cigarettes are a popular substitute for smoking products. The electronic devices heat liquid that includes flavoring, nicotine and other chemicals into vapor—very small particles that users breathe in. Nicotine is found in many plants, including tobacco. E-cigarettes or similar devices also can provide THC or other substances to users. THC is the natural chemical present in marijuana(大麻) plants that gives users the mental state known as a “high”.
E-cigarettes are said to be safer than normal cigarettes because they do not create the cancer-causing byproducts of burning tobacco.Yet health officials say e-cigarette users have reported shortness of breath and other breathing problems, such as coughing and chest pain. Some have been sick to the stomach, felt very tired, suffered weight loss or developed high body temperatures. One report noted that most of the 53 illnesses reported in Illinois and Wisconsin were related to THC vaping(气化) products. But nearly 20 percent of the patients inhaled(吸入)substances like nicotine from e-cigarettes. Most of the reported cases were of young men.
The report found that, “Since no single product or substance has been associated with the illness, persons should consider not using e-cigarettes while this investigation is ongoing.” Last November, The Centers for Disease Control and Prevention, or CDC, reported that “e-cigarette use increased considerably among U.S. middle and high school students during 2017—2018.” Among high school students, it found e-cigarette use rose from 220,000 students in 2011 to 3.05 million in 2018.
On Monday, the Food and Drug Administration, or FDA gave a warning to JUUL Labs, maker of the best-selling e-cigarettes. The FDA accused the company of illegally marketing its products as being “safer than cigarettes” without the agency's approval.In a statement, the FDA's acting commissioner said that, “JUUL has ignored the law, and has made some of these statements in school to our nation's youth.” A JUUL spokesman said the company is studying the FDA's comments and “will fully cooperate”.

For all the technological wonders of modem medicine, health care-with its fax machines and clipboards(写字板)—is out of date. This outdated era is slowly drawing to a close as the industry catches up with the artificial-intelligence ( AI) revolution.
Eric Topol, an expert in heart disease and enthusiast for digital medicine, thinks AI will be particularly useful for such tasks as examining images, observing heart traces for abnormalities or turning doctors' words into patient records. It will be able to use masses of data to work out the best treatments, and improve workflows in hospitals. In short, AI is set to save time, lives and money.
The fear some people have is that AI will be used to deepen the assembly-line culture of modem medicine. If it gives a “ gift of time” to doctors, they argue that this bonus should be used to extend consultations, rather than simply speeding through them more efficiently.
That is a fine idea, but as health swallows an ever-bigger share of national wealth, greater efficiency is exactly what is needed, at least so far as governments and insurers are concerned. Otherwise, rich societies may fail to cope with the needs of ageing and growing populations. An extra five minutes spent chatting with a patient is costly as well as valuable. The AI revolution will also enable managerial accountants to adjust and evaluate every aspect of treatment. The autonomy of the doctor will surely be weakened, especially, perhaps, in public-health systems which are duty-bound to cut unnecessary costs.
The Hippocratic Oath(誓言) holds that there is an art to medicine as well as a science, and that “warmth, sympathy and understanding may outweigh the surgeon's knife or the chemist's drug”. There's lots of sense in it: the patients of sympathetic physicians have been shown to recover better. Yet as the supply of human carers fails to satisfy the demand for health care, the future may involve consultations on smartphones and measurements monitored by chatbots. The considerately warmed stethoscope ( 听诊器) ,placed gently on a patient's back, may become a relic of the past.
1.What's Dr Topol's attitude toward AI's coming into medicine?
A.Concerned. B.Doubtful. C.Optimistic. D.Cautious.
2.What does the author of the text attach more importance to?
A.Medical costs. B.National wealth.
C.Longer consultation. D.Greater efficiency.
3.Why is the Hippocratic Oath mentioned?
A.To prove the bright future of AI.
B.To show the advantage of a human doctor.
C.To explain medical equipment is more important.
D.To argue a human doctor performs as well as a robot.
4.What may be the best title for the text?
A.Health care and AI B.AI and its applications
C.Doctors and Patients D.Dr Topol and digital medicine
Automatic dishwashers have been around for more than 100 years. It started in 1886 with Josephine Cochrane, a woman in Shelbyville, Illinois. She was a rich woman who could afford servants to wash her dishes, so she really didn’t mind the work. What she did mind was that her servants broke the dishes. She hosted quite a few dinner parties, and after every party the servants broke more of her expensive dishes.
Finally, Cochrane took action. First, she measured her dishes and bent wire into racks to hold them. Next, she put the racks on a wheel in a large copper boiler. Then, the boiler sprayed hot, soapy water on the dishes as a motor turned the wheel. After a hot water rinse(冲洗), the dishes were clean!
Josephine Cochrane’s friends were impressed with the machine and asked her to build more. After that, word got out fast. Soon hotel and restaurant owners who didn’t like broken dishes also were interested. Cochrane then knew that she had a wonderful machine, so she received a patent from the government, which said that only the inventor can make money from an invention. Then in 1893 Chicago held a World’s Fair where inventions from all over the world were shown. Cochrane’s labor-saving machine was a big hit. Her dishwasher won the highest award.
Cochrane’s company came out with a smaller machine in 1914. It was supposed to be for the ordinary home, but it wasn’t an immediate success. Many homes couldn’t produce the extremely hot water it needed. Also, in most homes, dishwashing wasn’t considered very difficult compared to most other housework. In fact some people liked to relax at the sink after a hard day! Sales of the home model finally picked up in the 1950s when people had more money and wanted to have more time to enjoy themselves. Now many homes have electric dishwashers that aren’t very different from the one Josephine Cochrane invented more than 100 years ago.
1.Why did Josephine Cochrane invent the dishwasher?
A.To reduce the number of servants.
B.To avoid possible damage to the dishes.
C.To host more dinner parties.
D.To make the dishes cleaner.
2.What does the underlined words in Paragraph 3 suggest?
A.The machine wasn’t as efficient as described.
B.Josephine Cochrane could no longer keep it a secret.
C.Josephine’s friends soon began to talk about the new machine.
D.The invention drew immediate attention of the public.
3.The smaller machine became popular only when_____.
A.people’s living conditions improved
B.hot water was not needed
C.housework became easier
D.people had more relaxing jobs
4.Compared with Cochrane’s invention, modern electric dishwashers _____.
A.cost less money
