Daniel's parents were worried about him.'He shouldn'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 (明智的) girl will marry him.' (2 )'1 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 Daniel's birthday. He was really looking forward to getting exciting presents. He woke up, expecting his parents to wish him a happy birthday. But all day what they said was' Good morning, Daniel. Hurry, or you will be late for school.' There were no presents, not even a card. He was really disappointed. 'Never mind,' he thought.(3) 'There'II 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?' Daniel asked. 'There must be a reason' 'Well, yes,' his father said.'We have a really good excuse for forgetting your birthday, Daniel. We didn't remember your birthday because we were too busy.' Poor Daniel! He never had a silly excuse for not doing something again. 1. 请把句(1)译成汉语。 ________________________________ 2. 请把句(2)改成同义句。 I don't know what _____ _____. 3. 请把句(3)改成间接引语。 He thought _______________________ 4.
