| Paul couldn't 1 last night. He woke up early and sat up, and he lay down again. He felt terrible. "I must be ill," he thought, "but I must study for that 2 ." He got up and looked for his history notebook. He finally found it on his chair. He 3 over his history notes, but he couldn't remember any of the facts in his notes. "What shall I do?" He felt terrible. Just then Paul's telephone rang, so he put down his notebook and picked up the telephone. "Good morning," Jack's voice said. "You must be wrong about the test." "What do you mean?" Paul asked weakly. "We aren't going to 4 today," Jack said. "I wrote down the date in my notebook. The test will be next Wednesday. It isn't today. 5 do you feel this morning?" "Fine," said Paul. "Just fine!" Suddenly he really felt fine. | ||||
