    Last Sunday, he went to the bakery   and bought some bread. Then he went to buy a pair of sneakers  . When he returned home, he turned on the TV to watch some commercials  about nutrition . Having eaten up the bread, he felt uncomfortable. He had to send for  a doctor. The doctor told him that the bread had gone bad.

    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's Los Angeles apartment, the monitor in Phoenix tracked 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 the cutting edge and a key to encourage honesty in the booming field of online education. The 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 just 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.

    I often read of incidents of misunderstanding or conflict. I'm left 1. Why do these people create mistrust and problems, especially with those from other 2?

    I was growing up in Kuala Lumpur in the early 1960s, 3 children from different races and religions played and studied 4 in harmony. At that time my family lived a stone's 5 from Ismail's. And no one was bothered that Ismail was a Malay Muslim and I was an Indian Hindu—we just 6 our differences. Perhaps, our elders had not filled our heads with unnecessary advice, well 7 or otherwise.

    We were nine when we became friends. During the school holidays, we'd 8 the countryside on our bicycles, hoping to 9 the unexpected. At times Ismail would accompany my family as we made a rare shopping trip to town. We would be glad of his 10.

    When I was twelve, my family moved to Johor. Ismail's family later returned to their village, and I 11 touch with him.

    One spring afternoon in 1983, I stopped a taxi in Kuala Lumpur. I 12 my destination. The driver acknowledged my 13 but did not move off. Instead, he looked 14 at me. "Raddar? "he said, using my childhood nickname(绰号). I was astonished at being so 15 addressed(称呼). Unexpectedly! It was Ismail! Even after two 16 we still recognized each other. Grasping his shoulder, I felt a true affection, something 17 to describe.

    If we can allow our children to be 18 without prejudice, they'll build friendships with people, regardless of race or religion, who will be 19 their side through thick and thin. On such friendships are societies built and 20 we can truly be, as William Shakespeare once wrote, "we happy few, we band of brothers".

    Mr. Smith had a 8-year-old son named Tony, who enjoyed listening to music very much. So he bought a piano to Tony, hoping that he can become a famous pianist one day. The little boy put her heart into practicing the piano day after day and seemed enjoy every minute of it. However, half a year later, he told his father that he was tiring of practicing the piano. Heard this, Mr. Smith said, “Tony, it is one thing to be fond of listening to music, and it is another thing to perform skillful by yourself. You can never play the piano well even if you don't practice more. ”
