To ‘mend’ trousers means: 1) to clean 2) to wash 3) to press 4) to repair

At the end of the week Father usually gets good ideas. Last Saturday when he was looking through the newspaper he found an article about skiing. He read it and said: “I don't remember when we last went skiing. What about trying it tomorrow?”
Everybody liked the idea so we started our preparations immediately. All of us wanted to look smart. Jane took out her sports clothes. Mother sent me out to buy skiing caps. When I came back she was mending Father's old trousers. She got angry when she saw the caps as they were all the same colour.
Late at night our clothes were ready and we could go to bed.
At 10 o'clock in the morning I suddenly woke up. The women were still sleeping. “Wake up everybody,” I shouted. “Stop joking in a silly way,” Mother said from her bedroom. “What about skiing?” I asked Father who was coming out of the bathroom. He paid no attention to my words. At breakfast he was reading his morning newspaper as usual and suddenly exclaimed: “Look, they say, swimming is the best way of losing weight. What about trying it?”
