    Artificial intelligence (AI) technology may soon be a useful tool for doctors. It may help them better understand and treat diseases like breast cancer in ways that were never before possible.

    Rishi Rawat teaches AI at the University of Southern California's (USC) Clinical Science Center in Los Angeles. He is part of a team of scientists who are researching how AI and machine learning can more easily recognize cancerous growths in the breast. Rawat provides information about cancer cells to a computer. He says this data helps the machine learn. “…You can put the data into them and they will learn the patterns and the pattern recognition that's important to making decisions.”

    David Agus is another USC researcher. He believes that “machines are not going to take the place of doctors.” He adds, “Computers will not treat patients, but they will help make certain decisions and look for things that the human brain can't recognize these patterns by itself.”

    Once a confirmed cancerous growth is removed, doctors still have to treat the patient to reduce the risk of cancer returning. The form of treatment depends on the kind of cancer. Currently, researchers take a thin piece of tissue, put it on a small piece of glass and add color to better see the cells. This process could take days or even longer. Scientists say artificial intelligence can do something better than just count cells. Through machine learning, it can recognize complex patterns, or structures, and learn how the cells are organized. The hope is that machines will soon be able to make a quick diagnosis(诊断)of cancer that is free of human mistakes.

    “All of a sudden, we have the computing power to really do it in real time...We couldn't have done this, we didn't have the computing power to do this several years ago, but now it's all changed.” Agus adds that the process could be done “for almost no cost in the developing world.” He says that having a large amount of information about patients is important for a machine to effectively do its job in medicine.

    A doctor faces a series of critical decisions every day. The best a doctor can do is to make those decisions as informed as possible. Some of them are still hard to make. A doctor can ask people of whom he values their opinions and that's it. Imagine discussing these with an AI system that is even more rational(理性的)than anyone else.

    The University of Southern California researchers are now only studying breast cancer. But doctors predict artificial intelligence will one day make a difference in all forms of cancer.

(1)、According to Rawat and David Agus, AI can be used to ___________.
A、take the place of doctors B、treat all forms of cancer C、remove doctors' mistakes D、help doctors diagnose cancer
(2)、From the passage, we learn that doctors may benefit from AI because it can ___________.
A、use data to recognize patterns of cancer B、decide on the form of cancer treatment C、reduce the risk of cancer returning D、monitor the medical procedure
(3)、What does the underlined word “critical” in Paragraph 6 mean?
A、reliable B、important C、evident D、doubtful
(4)、What's the best title for the passage?
A、How Do AI Systems Work? B、Can AI Cure Cancer? C、Can AI Make Doctors Better? D、How Can Doctors Use AI?
举一反三

    Bill Gates recently predicted that online learning will make place-based colleges less significant, and five years from now, students will be able to find the best lectures in the world online. I applaud Mr. Gates. But what's taking us so long?

    As early as 1997, MIT(麻省理工) decided to post videos of all university lectures online. for free, for all people. But today, how many students have you met who mastered advanced mathematics or nuclear physics from an MIT online video? Unfortunately, the answer is not many. The problem is the poor quality of online education websites and the experience they provide to students. Those who go to the MIT website and watch courses online are surely very smart people, but it's not like playing a video game such as World of Warcraft. Only the most ardent students, those who are highly motivated, will devote themselves to studying these boring online videos.

    The real question is why we aren't spending more to develop better online education platforms. Where is the Avatar of education? Think about this. The market for Hollywood films per year is worth around 30 billion USD. Education in the world is a trillion-dollar-a-year market, hundreds of times bigger than Hollywood movies. Yet the most expensive digital learning system ever built cost well under 100 million dollars.

    Bill Gates' prediction is going to happen. There is no doubt about it. But it will only happen when we create high level educational content and experiences that engage and excite more than has ever been possible in the real world.

    In the early 1980s, one of our neighbors asked my mom if she would make a few gift baskets for her to give as gifts for the holidays. My mom agreed and news of the unique gift baskets my mom was making spread like wildfire throughout the neighborhood. My mom was busy throughout the holiday season, so she asked a friend to help her. When the orders continued after the holiday season for baby gifts, birthday gifts and more, it occurred to them that maybe this job could be turned into a business and they did it.

    My mom went into her business because she had creative ideas. She got orders and filled order. But there was no goal and no real plan. In 1991, my mom's partner got into financial trouble and there was not enough money to support either mom or her partner.

    So if you are led by your creativity or enthusiasm, make sure you ask yourself what you purpose to do your business is. If you don't set goals, how will you know which direction to go in? Do you want to create jobs and growth in the economy? Are you looking for a hobby? You can't keep scores if you don't know what game you are playing.

    After my mom's partner quit, she had to abandon her business to support herself. She swore she would run a business again and do it differently the next time. However, there wasn't a “next time” for her. She passed away just after her 51st birthday. She never had someone tell her how important having a goal was, she never had a chance to be everything she could be.

    There are no right or wrong goals, only the ones that matter to you. Set them so that you can make progress and achieve success, whatever they may mean to you.

    Anyone who cares about what schools and colleges teach and how their students learn will be interested in the memoir (回忆录) of Ralph W. Tyler, who is one of the most famous men in American education.

    Born in Chicago in 1902, brought up and schooled in Nebraska, the 19-year-old college graduate Ralph Tyler became hooked on teaching while teaching as a science teacher in South Dakota and changed his major from medicine to education.

    Graduate work at the University of Chicago found him connected with honorable educators Charles Judd and W. W. Charters, whose ideas of teaching and testing had an effect on his later work. In 1927, he became a teacher of Ohio State University where he further developed a new method of testing.

    Tyler became well-known nationally in 1938, when he carried his work with the Eight-Year Study from Ohio State University to the University of Chicago at the invitation of Robed Hutchins.

    Tyler was the first director of the Center for Advanced Study in the Behavioral Sciences at Stanford, a position he held for fourteen years. There, he firmly believed that researchers should be free to seek an independent spirit in their work.

    Although Tyler officially retired (退休) in 1967, he never actually retired. He served on a long list of educational organizations in the United States and abroad. Even in his 80s he traveled across the country to advise teachers and management people on how to set objectives (目标) that develop the best teaching and learning within their schools.
