The other day, some of my classmates and I took a bicycle trip along the “Ren Min Road”, where was specially built for people to relax ourselves. The scenery along the road was fascinating, with trees, flowers, hills and lakes on both side. We stopped by a lake for a rest, where a good many of people were playing happily. But something unpleasant catch our attention. There was rubbish here or there, and there were many plastic bags and bottles floated on the surface of the lake. Such beautiful place was so serious polluted. What a shame! In the end, we couldn’t help collecting the rubbish after we left.

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(肿瘤) 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(活检). 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
B. we can use Artificial Intelligence to cure skin cancers

2.Which one will he agree with according to Dr Esteva?
A. Artificial Intelligence has beaten all of humanity’s best Go players.
B. Artificial Intelligence could support assessments by GPs.
C. We still need professional doctors with the help of the system.
D. There are too many disadvantages for Artificial Intelligence.

A. Cancer Doctors Are Out
