Japan is a mysterious land of technological wonders, but the latest is a relatively simple solution to an age-old problem faced by beginners and professional chefs alike.

Grocery stores across the country are about to start stocking onions that won’t make people cry. The new tear-free onion is called the Smile Ball, which is a pretty adorable name for a vegetable, and it’s an onion carefully engineered to not irritate (刺激) the eyes of people who cut into it.

Regular onions release a gas when their cells are damaged and that gas irritates people’s eyes and make them tear up. The Smile Ball onions release no such a gas, so they can be chopped easily. They are also sweet like fruit when eaten raw.

The scientific advancement of the tearless onion is not free, however. Smile Balls, developed by the Japanese producer House Foods, will cost about $4.30 for a pack of just two when they go on sale in supermarkets across Japan. That’s about double the cost of a normal onion, but it might be worth the extra money for those who are particularly sensitive to traditional onion gas. Earlier test sales of the tear-free onions were held in Tokyo, with the onions selling out quickly.

1.What do the people say about tear-free onions?

A. They’re too expensive to afford.

B. They’re sweeter than candies.

C. They're especially suitable for kids.

D. They’re worth buying, though expensive.

2.What can we learn about the Smile Ball?

A. It never gives off a strong gas.

B. It has a pretty look.

C. It belongs to a new kind of fruit.

D. It rarely goes bad.

3.What’s mainly discussed in the last paragraph?

A. How to produce tear-free onions.

B. Tearless onions are more popular.

C. The development of House Foods.

D. People are sensitive to tearless onions.

4.What can be the suitable title of the text?

A. Say Goodbye to Regular Onions

B. Tear-free Onions vs Regular Onions

C. Onions That Don’t Make You Cry

D. The Future of Tear-free Onions

The age of technology is a great and convenient thing, but it does have effects on us in many different ways.

It causes long-term memory loss. Thanks to Baidu, we don't really have to remember much of anything. Questions are answered at the drop of a hat because Baidu is all-knowing! Is that a good thing, though? People aren't digging through their brains anymore to find answers. Here's the good news: we can still exercise our long-term memory by simply thinking before we Baidu. If we don't want to go down that road, we can search Baidu for some memory games to play. Turn Baidu into an asset instead of an enemy.

It makes us lack patience. Baidu gives us what we want. Everything is instant. In fact, if we have to wait for even a handful of minutes for anything, we start losing our minds. This idea of instant satisfaction carries through to many other aspects of our lives, too, like when we go out to eat, drive in traffic, or even deal with workplace accidents. Instead of using Baidu to lessen our anger, try searching for some mindful meditations (沉思).Focus on our breath and realize everything doesn't have to move at lightening speed. We can actually listen to some peaceful spa or meditation music on our Pandora, too!

It wastes our time. Be honest, how much time are we spending on Baidu every day? Whether we're doing research for our own personal needs, buying clothing, or writing a research paper, we all spend a ton of time on the trusty Internet. Are we always being efficient with this time? For the sake of our precious time, if we haven't used Baidu Drive, we should. Keep spreadsheets, text docs, PDFs, slideshows, and even recordings exactly where we can easily find them. Keep a running list of websites we know we'll revisit.

Overall, things are different these days. Yes, there are noticeable negative side effects because of the Baidu invasion, but we don't have to fall into that trap. Stay sharp and don't let ourselves become imprisoned doing the Baidu god's bidding.

1.Which of the following can best replace the underlined part “at the drop of a hat”?

A.at one point B.in no time C.in a way D.at a loss

2.Why do we turn impatient in real life according to paragraph 3?

A.We depend on ourselves too much.

B.We can't get everything with Baidu.

C.We can't get quick services in real life.

D.We get used to Baidu's quick convenience.

3.What is the author's advice on saving time online?

A.Using Baidu Drive.

B.Keeping papers correctly.

C.Being efficient with work.

D.Emptying websites records timely.

4.What does the text mainly tell us?

A.The side effects of Baidu and solutions.

B.The advantages and functions of Baidu.

C.The technology and influence of the Internet.

D.The disadvantages and risks of the Internet.

Japan has long been known for both its strong traditions and being on the cutting edge of technology, and this new inn combining the classic Japanese surroundings with high-tech slippers and furniture is a perfect reflection of this.

Nissan Motor Co. developed a system in which slippers park themselves at the entrance of the traditional inn, called “ProPilot Park Ryokan,” waiting for guests to use them upon arrival. When guests have finished using them, the slippers will drive themselves back to their original position. Each slipper features two tiny wheels, a motor, and sensors to drive it across the wooden floor.

The same technology features in Nissan’s all-battery electric Leaf car. High-tech sensors and cameras allow the vehicle to safely back into parking spaces without any input from the driver. Four cameras and 12 sensors assess the vehicle’s surroundings. ProPilot Park handles the accelerator, braking and steering (转向) input when the car is parking. Drivers operate the system with the press of a button, which they must hold down the entire time. Lifting a finger off the button will result in the car stopping immediately.

The inn, located in the resort town of Hakone, about 75 kilometers southwest of Tokyo, is currently most famous for its view of Mount Fuji. However, the new self-driving slippers, released by Nissan in March, is the unique feature of the high-tech inn.

“The self-parking slippers are meant to raise awareness of automated driving technologies, and their potential, non-driving applications,” Nissan spokesman Nick Maxfield said in a statement.

In addition to the slippers, office chairs, floor cushions and traditional low tables in the inn also wheel themselves back into place after use.

1.What is the typical feature of the slippers?

A. They are eco-friendly.　　 B. They are automatic.

C. They are recyclable.　　 D. They are rechargeable.

2.How can a driver stop the Nissan’s electric Leaf car?

A. By pressing a button.　　 B. By using the brake of the car.

C. By removing the finger from the button.　　 D. By handling the accelerator.

3.Why did Nissan develop the slippers according to Nick Maxfield?

A. To attract more customers.

B. To advertise the Nissan Motor Co.

C. To lessen work load of the workers.

D. To promote non-driving technologies.

4.What can we know about the inn mentioned in the text?

A. It uses robots to serve the guests.

B. It is famous for its good service.

C. It is a combination of tradition and modem.

D. It is known for its beautiful decoration.

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

高三英语阅读理解简单题查看答案及解析

It is one of the greatest mysteries of nature. In case you haven’t noticed, all living things follow very definite, individual rhythms, all as regular as a clock, but what makes them regular?

Though many scientists maintain that these rhythms are the result of some outside force like gravity or radiation or both, the results of most scientific researches agree with other scientists who believe that each living thing has its own built-in biological “time clock.”

Take the mystery of migration for example. Scientists can’t really explain why many species of birds migrate in the autumn even though the temperature is still summery. The birds just seem to snub the comfortable weather that they are having. When a certain time comes, they travel south by the thousand. In spring time, they migrate northwards even though there probably is snow still covering the ground when they finally arrive. Something said “go,” and they did.

Animals that hibernate (冬眠) are obeying individual time clocks, too. When their clock indicates the time to take a winter’s nap, they do, and nothing can stop them. At a certain time in the spring, they wake up and come out regardless of the weather outside.

Plants appear to have yearly rhythms, such as the sprouting of seeds, and they also have daily rhythms. Notice sometimes that plants raise their leaves in daylight and lower them at night.

If you live along the California coast, you can easily observe a demonstration of this mysterious clock functioning regularly. There, from February to September, the highest tides occur exactly every fourteen and four-fifths days, and during these high tides, but at no other time, small silvery fish called grunions surf-ride a wave to the beach. There the female deposits her eggs in the sand and the male fertilizes them; then both hitch a wave-ride back to the sea. Exactly fourteen and four-fifths days later, never before or after, the tiny eggs hatch, and the high tide carries the new babies out to sea.

72. According to the passage, the mysterious rhythms result from ______.

A. the influence of gravity on living species

B. the effect of radiation on living species

C. the influence of a mysterious outer force on living species

D. the internal mechanism inside the living species

73. The underlined word “snub” in the third paragraph probably means ______.

A. fight   B. ignore C. symbolize   D. criticize

74. Which of the following statements is NOT TRUE?

A. Hibernating animals are obeying an internal time clock.

B. The positioning of the leaves of some plants is due to the daily rhythms.

C. The internal clock functioning is demonstrated in the reproducing habits of grunions.

D. The yearly hibernation is more because of the weather influence than the biological functioning.

75. The passage is mainly about ______.

A. the rhythms of life

B. the reasons of mysterious hibernation

C. strange behaviors of species

D. the timing for different events in the world of species
