Twenty years ago,getting sick meant visiting a doctor.Now,many internet tools seek to identify what disease a person has based on symptoms described.The following are some studies.
Study 1
A study led by an American researcher showed these web-based tools may be useful for patients who are trying to decide whether they should get to a doctor quickly.
Besides,online symptom checkers can help seriously-ill patients for a guided care.According to the findings,overall the 23 symptom checkers provided correct advice in 58 percent of cases in more critical cases.
Study2
Australian researchers at Edith Cowan University in Perth.did a new study,which examined 36 international internet-based symptom checkers,finding these online symptom checkers were rarely correct and could be harmful.
Michella Hill,a leader of the research,said,"While it may be tempting to use these tools to find out what may be causing your symptoms,most of the time they are unreliable and sometimes can be dangerous.”
With the development of new technology, online symptom checkers are being used by more and more people. Some studies show that it is beneficial to citizens while others demonstrate that it may lead to bad results.
On a personal level, I would rather turn to these online symptom checkers in the first place, once I feel uncomfortable physically. Firstly, the development of the online symptom checkers is based on artificial intelligence, Surely, which has been widely applied in medicine. Secondly, since all you need to do is click a mouse and type your symptoms which have been stored in the database, these tools can surely save you a lot of time and money compared to visit a doctor in a hospital. Finally, if people can handle some common diseases themselves at home, it will greatly free more doctors to treat those in greatest need.
I’m sure the symptom checkers make sense, especially during an epidemic.
Version 2
With the development of new technology, online symptom checkers are being used by more and more people. Some studies show that it is beneficial to citizens while others demonstrate that it may lead to bad results.
As far as I can see, it is no good trusting the online symptom checkers when you feel sick. One of the main problems is that such tools don’t know your medical history or other symptoms. Accordingly, depending on too little information, they are likely to make a wrong or partial diagnosis. Then, people will be told to get care when they don’t need it and bear the costs and inconvenience. What’s more, making a diagnosis is sometimes a matter of life and death. However, the tools won’t bear the corresponding responsibilities for their mistakes.
On the whole, while they can fill a need in the modern health system, the online symptom checkers are far from a replacement for going to the doctor.

Zhang, 44, an employee of a company in Yichang, Hubei province, first donated blood in 1998 while studying at Wuhan University of Technology. “It was in the summer when I was with my classmates, and medical workers were promoting the idea of voluntary blood donations, ” she recalled. To mark her upcoming graduation with a degree in international trade and commerce, she decided to donate 200 milliliters of blood. “In fact, I was jittery at first, ”she said. “But with the nurse explaining things and providing guidance, I gained basic knowledge and finally calmly finished the blood donation.”

【題目】Clara Barton, born on Christmas in 1821, is widely known as one of the most honored women in American history. She began teaching school when most teachers were men at that time. Later, she became one of the first women ever to be employed by the government.
Her career in helping the sick began when her brother David became her first patient. He fell down from the roof of a house when Clara was just 11 years old. She stayed by his side and looked after him for three years, learning how to give him all his medicines.
When the Civil War began in 1861, she immediately recognized that the poorly equipped soldiers needed help. Instead of waiting for others to step in, Clara collected necessary things on her own, asked the public for donations and learned how to store and distribute them to soldiers. She also read to the soldiers and wrote letters for them.
After the Battle of Cedar Mountain in northern Virginia in 1862, Clara arrived at a field hospital at midnight with a vehicle full of supplies. A doctor named Paul Smith at that hospital would later write, “I thought heaven had sent out an angel that night — her assistance arrived at exactly the right time.”
In 1869, Clara went to Europe and learned about the International Committee of the Red Cross. Upon her return to the United States, she successfully founded the American Red Cross. She led the organization for the next 23 years. Her last field mission (使命) as president of the American Red Cross was to help the victims of the 1900 Galveston hurricane. She did not retire (退休) from the American Red Cross until she was 83. True to her nature, Clara always went to where the need was the greatest.

【題目】Auckland University Online Education-What to Expect
Most Auckland University (AU) online programs are 100 percent online so that students do not come to the school campus. Instead, AU has designed a media-rich, easy-to-use learning environment through a Learning Management System (LMS)
Discipline (紀律)
With disciplined work habits, you are likely to succeed as an online student. It is up to you to log on to your course and meet your own deadlines.
Time Management
In order to earn competitive grades, plan on spending a minimum of 20-25 hours a week on each course. AU courses operate on a seven-week schedule, with start dates in January, March, May, July, September and November. Students are able to complete two courses per semester by taking one seven-week course at a time
Professional Connections
Many of the AU faculty (教員) who teach online have connections to industry, so the online learning environment ensures access to diverse expertise and practice. It includes an extensive network of professionals in a variety of industries.
“I work as an IT manager: And right from the very beginning, every class I took was relevant to what I was doing at work. The wide range of courses gave me a strong foundation for my career development.”
——Jim Heilman, Computer Information System graduate
Technology
It goes without saying that technology plays a vital role in online learning. You will need a high-speed Internet connection and basic computer skills. For specifics, please click here to visit our Technology page.
