根据短文内容的理解,选择正确答案。 After breakfast Mrs. Beckman started packing(打包)the bags. She bought the tickets to London. Her husband works there. She and her children are going to fly there to see him. Thomas and Katy can't help her and she told them to play outside.
"It often rains in London in autumn," the woman said to herself, " I'd better take the umbrellas. So I won't buy any when it rains there."
Suddenly(突然), she heard Thomas crying and ran out at once. She asked, " What's the matter?"
"Katy pulled(揪)my hair," the boy said in tears(眼泪汪汪地).
"Don't be angry," said the woman. "She's too young. She doesn't know pulling hair hurts(疼痛)"
And then she went to the house again. After a short time there was more crying. She had to come out to see what the matter was.
This time Thomas said, "Now she knows."
