     Mrs. Smith often felt lonely when her husband went to work. The room was small and it took her only

 half an hour to tidy it. She couldn't get up early in the morning, so Mr. Smith had to cook breakfast

 himself. She usually had some bread and milk for lunch and only cooked spper for herself and her husband. They had no television. Mr. Smith always went to bed at nine.

     It was a winter morning. The sun was shining and it was warmer outside than it in the room. The woman

  sat on the step of a shop, 100-king at the busy traffic.  At that moment a man with a map in his hand was

  coming towards her.

     "Excuse me, madam," said the man. "Could you tell me how to get to the nearest hospital, please?"

     Mrs. Smith looked at him up and down. "He seems to be a farmer," the woman said to herself.  "Let

 me play a joke on him. " Then she turned to him and said, "Lie down in the middle of the street and you'll

 soon be sent to a hospital. "

     "Please set an example to me, then," said the man.

     She had to tell the way to him and then she said, "I think you have been in a city for the first time.  It's

 much more beautiful than the field. Is that right?"

     "Yes, madam," said the farmer with a smile  "But I think it was built on the field! "

在大气组成成分中，唯一能够发生相变的大气成分是水汽。

一钢筋混凝土排架，由于三种荷载（不包括柱自重）使排架柱柱脚A处产生三个柱脚弯矩标准值，M_Agk=50kN·m、M_Aqk=30kN·m、M_Ack=60kN·m（见下图），M_Agk是柱顶处屋面桁架上永久荷载的偏心反力产生的，M_Aqk是柱顶处屋面桁架上活荷载的偏心反力产生的，M_Ack是柱中部吊车梁上A5级软钩吊车荷载的偏心反力产生的。风荷载作用下产生的柱脚弯矩标准值M_Awk=65kN.m（见下图）。

采用《建筑结构荷载规范》（GB50009-2012）第3.2.4条的简化规则，计算在四种荷载下柱脚A处的最大弯矩设计值M_A应为（）kN·m。

A.255.3

B.239.2

C.228

D.210.3
