THE ENGLISH LESSON
Miss Marvel walked into her classroom and opened her school bag. The worksheets she needed were
not there! No problem. There was a good exercise on the computer. She logged on, but, disaster - her
computer crashed! The topic was the past simple tense. She found a book, opened it and
started reading a story. However, it was boring and the class didn't settle. First, Peter
threw a pen at Julia. Mick swung back and forward on his chair. Jenny barked like a dog and
Saima meowed like a cat. Just at that moment, the door opened and the head teacher walked
in! He went to the back of the class and sat down. He was observing the lesson! Poor Miss
Marvel did not know what to do! Suddenly, a cat climbed in through the window. He walked to the front
of the room and jumped onto Miss Marvel's desk, sat down and licked his paws. Then, he rolled onto his
back, put his legs in the air and he purred. Now, the students were interested and they paid attention.
'Right, class!' said Miss Marvel. 'What did the cat do first?'
They all put their hands up and Miss Marvel chose Jim.
'He coming in through the window, Miss', Jim answered.
'He coming in or he ca..?' Miss Marvel asked.
'He came in!' Eventually Jim remembered the correct ending!
Miss Marvel asked lots of questions and soon, they described all the things the cat did. Then Miss
Marvel told them to open their books and write down the cat's actions, in the correct order. She told
them to use: first, then, next, after that and finally. They all opened their books and started to write.
Miss Marvel heaved a sigh of relief and the head teacher smiled. Just then, her computer sprang back
to life.
