Artificial intelligence can ide ntify skin cancer in photographs with the same accuracy as trained doctors, say scientists. The Stanford University team said the findings were "incredibly exciting" and would now be tested in clinics. Eventually, they believe using AI could revolutionize healthcare by turning anyone’s smart-phone into a cancer scanner.

The AI was repurposed from software developed by Google that had learned to spot the difference between images of cats and dogs. It was shown 129,450 photographs and told what type of skin condition it was looking at in each one.

It then learned to spot the hallmarks of the most common type of skin cancer: carcinoma, and the most deadly: melanoma(黑色素瘤). Only one in 20 skin cancers are melanoma, yet the tumor(腫瘤) accounts for three-quarters of skin cancer deaths.

The experiment, detailed in the journal Nature, then tested the AI against 21 trained skin cancer doctors. One of the researchers, Dr Andre Esteva, told the BBC News website: "We find excitedly, in general, that we are on par with excellent skin cancer doctors."

However, the computer software cannot make a full diagnosis, as this is normally confirmed with a tissue biopsy(活檢). Dr Esteva said the system now needed to be tested alongside doctors in the clinic. "The application of AI to healthcare is, we believe, an incredibly exciting area of research that can be leveraged to achieve a great deal of societal good," he said. "One particular route that we find exciting is the use of this algorithm on a mobile device, but to achieve this we would have to build an app and test its accuracy directly from a mobile device." Incredible advances in machine-learning have already led to AI beating one of humanity's best Go players.

And a team of doctors in London have trained AI to predict when the heart will fail.

A. Artificial Intelligence must replace human one day

C. We still need professional doctors with the help of the system.

D. There are too many disadvantages for Artificial Intelligence.

3.The underlined words “on par with” in Para 4 likely mean ________.

“Her grades are fine; I’m not worried about that, but she just doesn’t seem to love learning any more.” Alice’s mum said.

She’s absolutely right. I’d noticed the same thing about her daughter over the previous two or three years when I’d been Alice’s middle school English, Latin, and writing teacher, and I have an answer, right there on the tip of my tongue, for what has gone wrong. Yet I’m torn between my responsibility to help Alice, and the knowledge that what I have to say is a truth I’m not sure this mother is ready to hear.

The truth—for this parent and so many others—is this: Her child has sacrificed her natural curiosity and love of learning at the altar(圣壇) of achievement, and it’s our fault. Alice’s parents, her teachers, society at large—we are all supposed to be blamed in this crime against learning. From her first day of school, we pointed her toward that altar and trained her to measure her progress by means of points, scores, and awards. We taught Alice that her potential is tied to her intellect(智力) ,and that her intellect is more important than her character. We taught her to come home proudly bearing grades As, championship prizes, and college acceptances, and not on purpose, we taught her that we don’t really care how she obtains them. We taught her to protect her academic and extracurricular perfection at all costs and that it’s better to quit when things get challenging rather than risk losing that perfect record. Above all else, we taught her fear failure. That fear is what has destroyed her love of learning.

1.Both the mother and the teacher have noticed that ________.

A. Alice hates to tell them truth

B. Alice’s test scores are not so good

C. Alice chooses several subjects to learn

D. Alice doesn’t enjoy studying any more

2.What does the underlined word “torn” mean in the passage?

A. pained to choose B. guilty to quit C. tired to manage D. certain to decide

3.What does the teacher think of the girl?

A. Her academic perfection resulted from her character.

B. She is a gifted girl with spirits of challenging.

C. She is perfect in her character development.

D. Her academic performance is great.

4.What leads to the girl’s change?

A. A few failure experiences. B. Fear of failing getting good grades.

C. Her mother’s over-protection. D. Her not being accepted by colleges.

Unlike most other holidays,the history of April Fools’ Day.Sometimes called All Fools’ Day,is not totally clear.The only point in time that can be agreed on as the beginning of this tradition was 1582,in France.Before that year,the New Year was celebrated for eight days,beginning on March 25.The celebration reached the highest point on April 1.With the reform of the calendar under Charles 1X,the the Gregorian calendar(公歷,陽歷)was introduced,and New Year’s Day was moved to January 1.

However,because in those days communications were not as developed as they are today,many people did not receive the news for several years.Some people refused to accept the new calendar and continued to celebrate the New Year on April 1.These backward people were considered”fools” by other people.They were often sent on “fools” errands(徒勞無益的工作)or were made the targets of jokes.

This developed,over time,into a tradition of playing a trick on someone on the first day of April.The tradition eventually spread to England and Scotland in the eighteenth century.It was later introduced to the American colonies of both the Britain and France.April Fools’ Day thus developed into an international fun feast,so to speak,with different nationalities specializing in their own kind of humor at the expense of their friends and families.
