I. Read the text and do the tasks.
A Smart Lesson
Harry was always making excuses for forgetting to do things. His usual excuse was "I was too busy" or "I
didn't have time". Harry's parents were worried about him. "He mustn't go through life making excuses
all the time", his father said. "No one will trust him to do anything. He won't be able to keep a job. No
sensible girl will want to marry him".
"I don't know what we can do", his mother said.
"I have an idea", his father said. "If this doesn't work, nothing will".
The next day was Harry's birthday. He was really looking forward to getting exciting presents. He woke
up expecting his parents to wish him "Happy Birthday!" but all they said was "Good morning. Harry.
Hurry, or you'll be late for school". There were no presents, not even a card. He was very disappointed.
"Never mind", he thought. "There'll be a surprise for me after school". But there wasn't. Sadly he said to
his parents at dinner, "Today's my birthday". "Oh!" his father said. "So it is. I forgot.'
"So did I", his mother said. "How could you forget?" Harry asked. "There must be a reason". "Well, yes",
his father said. "We have a really good excuse for forgetting your birthday, Harry. We didn't remember
your birthday because we were too busy". Poor Harry. He never had a silly excuse for not doing
something again.
1. Answer the questions.
1) What did Harry make excuse for?
2) Whose birthday was it the next day?
3) What was he hoping to get?
4) What was he expecting when he woke up?
5) What did he get for his birthday?
