Mary will ever forget the first time she saw him. He suddenly appeared in class one day ,   16  (wear) sun glasses . He walked in as if he    17  (buy) the school ,And the word quickly got around that he was from New York City .

For some reason he sat beside Mary. Mary felt    18  (please), because there were many empty seats in the room .But she quickly realized that it wasn’t her, it was probably the fact that she sat in    19  last row.

   20   he thought he could escape attention by sitting at the back, he was wrong. It might have made it a little    21  (hard) for everybody because it meant they had to turn around, but that didn’t stop the kids in the class. Of course whenever they turn to look at him, they had to look at Mary ,   22   made her feel like a star .

“Do you need those glasses for medical reasons ?” the teacher asked .The new boy shook his head .”Then I’d appreciate it if you didn’t wear them in class .I like to look at your eyes when I’m speaking to you.” The new boy looked at the teacher    23   a few seconds and all the other students wondered    24   the boy would do .Then he took    25   off , gave a big smile and said “That is cool.”
