While Jennifer was at home taking an online exam for her business law class, a monitor（监控器）a few hundred miles away was watching her every move.
Using a web camera equipped in Jennifer'sLos Angelesapartment, the monitor inPhoenixtracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked remotely to prevent Internet searches, and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past？Or was she slowing down？
In the battle against cheating, this is thecutting edgeand a key to encourage honesty in the booming field of online education. This technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid — that students haven't searched the Internet to get the right answers.
Although online classes have existed for more than a decade, the concern over cheating has become sharper in the last year with the growth of "open online courses". Private colleges, public universities and corporations are jumping into the online education field, spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance.
Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check students’ identities using personal information, such as the telephone numbers they once used.
Other programs can produce unique exams by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test questions are answered at the same speed as easy ones. As in many university classes, term papers are scanned against some large Internet data banks for cheating.

A Virginia teen is doing his part to make sure frontline health care workers are getting the meals they need to help them take care of themselves and others.
Arul Nigam, 17, of Tyson's Corner, Va. , has had to make several adjustments since his school year ended abruptly in mid-March due to the coronavirus pandemic(新冠疫情).“We didn'thave any classes for like over a month and then after that there were a lot of technical difficulties.

As artificial intelligence(AI) systems become more advanced, we can expect them to be used more often in the world of human medicine and healthcare. AI is designed to imitate(模仿）the human brain in decision making and learning, so with the computing power to learn tasks in days or even hours, it is possible to create medical AIs that rapidly outperform doctors in certain tasks.
Data plays a hugely important role in helping AI systems learn about human medicine. AI systems are trained on large data sets gathered from real-life cases. Providing detailed patient information in quantities is a crucial factor for their success.
One of the most important areas for influencing global health is in the field of epidemiology(流行病学）。

Predicting disease outbreaks can save millions of lives by having resources ready should the worst happen. Startup AIME has successfully combined public health data with machine learning and AI to create a prediction engine capable of anticipating epidemics months in advance with great accuracy.
Another field where medical AIs are making rapid advances is in diagnostics(诊断学）Doctors base a lot of decisions on information from X-ray, CT and MRI images. Speeding up. diagnoses from patient scans can rapidly improve patient care and outcomes. Computer vision AIs use pattern recognition to work through these images with incredible speed and accuracy. They have been able to outperform junior doctors and even senior specialists in some tests.
Cardiologist(心脏科医生）Rima Arnaout developed an AI that beat human experts at correctly interpreting echocardiograms(超声心动图）by 92 percent to 79 percent. She said that despite the result there is no prospect of AI replacing human doctors any time soon. “As cardiologists, weread the images and then go to see the patient,” she said. “So we're both reading images and practicing medicine. I don't think that the second piece will be taken over so quickly. ”
The acceptance of AI in medicine will continue to gather pace in the future as it becomes more widespread.
12. What played a big role in helping AI systems know of human medicine?
A. Certain tasks.
B. Large data.
C. The skill to imitate.
D. The increasing demand.
13. Why is Startup AIME mentioned in paragraph 3?
A. To illustrate predicting disease is possible.
B. To call on doctors to focus on public health data.
C. To prove it's a successful company in global health.
D. To let readers realize the importance of early success.
14. What do we know about computer vision AIs?
A. They do better than doctors in some tests.
B. They speed up diagnoses from patient scans.
C. They can rapidly improve patients' conditions.
D. They analyze information from X-ray, CT and MRI images.
15. What do Rima Arnaout's words in paragraph 5 imply?
A. AIs are not so smart as human doctors.
B It's not easy for AIs to take the place of human doctors.
C. A cooperation between AIs and human doctors is a must.
D. Human doctors are playing a big role in practicing medicine.
