1 . 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.

2 . Sunstroke is a condition that can quickly go from dangerous to deadly, especially if proper care isn’t given immediately.

Sunstroke, sometimes called heatstroke, is a result of the body temperature rising above safe limits. This causes the body’s necessary functions to stop working.

It’s usually pretty easy to avoid sunstroke, as long as proper action is taken. In that case, you need to act as quickly as possible to return that person’s body to a safe temperature. Here are a few tips to help treat sunstroke.

Call for help

Call to get an ambulance as quickly as possible. This should be the first thing you do, especially if the sunstroked person has fainted (昏迷). Also, call for help from anyone nearby if you’re in a public place. If there’s no one around, call someone nearby if they can get there sooner than an ambulance. Ask everyone to bring you as much water as possible, if there isn’t much nearby.

Get the person to a cooler area

If there’s a building nearby, aim for that. Anywhere with plenty of air conditioning and water is perfect. If a building isn’t available, bring the person to a well shaded area.

Get the water flowing

If the person is still conscious, get him or her to drink water. If there’s a bathtub available, fill it with cool water and put the person in it.

If your water supply is limited, you have to save it. Dampen a towel or shirt and put it on the person’s body. Focus on the face, neck, and chest.

Fan the person

Getting moving air over the person cools him or her down. Use anything, a towel or sheet, a shirt, your hands, or a piece of board. This is where having many people around really helps, as they can combine to fan the entire body.

1. When does a person get sunstrok?

A．When the body doesn’t function.

B．When proper care is given immediately.

C．When someone is exposed to the sun too long.

D．When the body temperature goes up beyond what one can bear.

2. What is mainly discussed in the passage?

A．The first aid for sunstroke.

B．The cause of sunstroke.

C．The chief symptoms of sunstroke.

D．The essential preventions of sunstroke.

3. Which of the following is NOT mentioned in the text?

A．To call for assistance from others.

B．To leave the sunstroked person in the shade.

C．To apply a wet towel to the person’s face.

D．To help the person take some medicine.

4. The text probably comes from       .

A．a guide book	B．a book review
C．a medical magazine	D．an official document

4 . If a person forgets names, places or facts —and has trouble with everyday things like reading or shopping —it may not mean you are getting old. It could be Alzheimer’s disease. So it’s important to see a doctor as soon as you can.

There is no cure for Alzheimer’s. But a drug called ARICEPT has been used by millions of people to help their symptoms (症状).

In studies, ARICEPT has been proved to work for Alzheimer’s. It has helped people improve their memory over time. It has also helped them to keep doing everyday things on their own.

Ask your doctor if ARICEPT is right for you or your loved one. It is the Number One drug for Alzheimer’s in the world. The sooner you know it’s Alzheimer’s, the better ARICEPT can help.

ARICEPT is good for many but may not be good for everyone. Some people may experience not sleeping well, feeling very tired, or not wanting to eat. In studies, these side effects weren’t serious at all and went away over time. Some people taking ARICEPT may feel light-headed. In this case you should tell your doctors because your condition may get worse.
