1. (2019·岳池模拟) 阅读理解

    Mike teaches a very basic programming (编程) course to a group of students. They are all very interested in computers.

    One day, Mike told his students to write a short program on their computers. After writing it, they only needed to type "R", "U" and "N" and press "enter" to see the program run.

    Soon, a student sitting in the back of the classroom put up her hand. She said, "I did what you said, but it didn't work." Mike knew that students sometimes make mistakes when typing. So he suggested that the student retype (重新输入) "R", "U" and "N".

    A few seconds later, the student's hand went up again. "It still doesn't work," she said. This time. Mike went to her to see what the problem was. To his surprise, he found that instead of typing "RUN", the student had typed "ARE YOU IN"!
