阅读理解。 'What's happened to the bottle of medicine?' He couldn't find it in this usual place on a table in the sitting room.' What have you done with it?' he asked his wife. She said she hadn't seen it, and told him it was probably under his nose, if he'd only open his eyes and look. He went into their son's bedroom to read him his bedtime story. On the floor there lay a bottle, the one he'd been looking for; but it was empty.'David what have you done with those sweet tablets which were in that bottle? Did you eat them?' David nodded.'How many did you eat?' No reply. He called his wife. She came, realized what had happened and went very white.'There must have been twenty-five or thirty tablets left in the bottle. He can't have taken them all,' said the father, feeling rather amazed. They searched the whole room, but there were no tablets on the floor, or in David's bed. David and his mother and father hurried to the nearest hospital. 'Put the boy on the stomach pump at once,' said the doctor, as soon as he heard the facts. They could hear David crying as they sat in the waiting room that was the worst of it, for they were wondering if the child was going to be all right, but unable to do anything except wait. The crying stopped and the doctor came back.'Lucky you brought him quickly. The tablets don't have time to dissolve in his stomach, so we got them all out. He's going to be all right.' They took David home, and bought a medicine box with a lock on it the next day. 1. The bottle of medicine is most probably for _______. A. the husband B. the wife C. the son D. somebody else 2.
