I was very lucky to meet Angelina,our head teacher. Before that,I always did nothing but watched movies and hung out with  11  of my best friends. We were in the same grade. It was only  12  of my previous (之前的)school.
Angelina was from Argentina. She was not only a teacher but an inventor. She created  13  recyclable plastics when she was young. And she was  14  winner of Environment Stars in
Argentina. She came to our school in the late  15 .
“I first tried inventing a new kind of plastic when I was an 16  girl,” she said. She started working at about 4 am before school and spent long hours at night. “When I failed three times,but I still hoped for  17  chance,” she said. When she was in her  18 ,she won several prizes.
Last year Angelina celebrated her  19  birthday at our school. “That was the first time I had my birthday party in China,” Angelina told us. “The experience was nice! I hope I can have  20  more time to have such a party in China.”
I've changed a lot and I am working hard now.

But today is a bit different. The coming supper is the last get together party for the students in our grade. In a month,we will enter different classes. How sad it is! The party will be held in the Joy Hall, 2  of the biggest canteen halls in our
school. With the help of the parents,we get a lot of snacks,such as candies,ice creams and crisps. The food takes up almost  3  fifths of the hall. The students and the parents take up the rest three  4 . The dinner time will last for  5  and a half hours to 7:45 pm. Then it's time for the  6  of us,Christine,Cherry and Carol to celebrate their birthday. We prepare a big birthday cake for them. For Carol,it is an unforgettable experience. As a new student,she will
have her  7  birthday party here. Although the other  8  girls has already had the experience,they still feel happy and excited. After the party,it's time for us to go back home.

Annie a retired (退休) teacher. She is very happy that she can join in the  11  anniversary (周年) celebration again.
Annie was in her 12  when she became a teacher fifty years ago. She still remembers clearly the  13  lesson she gave as a new teacher.
It was a sunny morning. I was surprised to see 14  notes on the teacher's desk when I entered the classroom. One said, “Dear Miss Annie, you are welcome from all the  15 girls. How many girls are there in the class?” and the other said, “Miss Annie, you are welcome from all the boys. There are as many boys as girls.” I counted and counted, “twenty girls and twenty 16  boys. One girl is missing.” “No,” they all laughed, “The missing girl is you.”
Now Annie in her 17  and the school is one  18  years old. However, Annie will still feel young when she is in her  19  , nineties and she is expecting the next anniversary—the  20  anniversary.
