男，4岁。1岁时诊断为佝偻病，给予钙剂及维生素D治疗，现钙、磷、碱性磷酸酶均正常，但仍遗留中度"O"形腿，应给予（）
A.按摩腿外侧肌群
B.作俯卧位抬头展胸运动
C.手术矫正畸形
D.口服维生素D+钙
E.使用突击量维生素D
参考答案：A
解析：此患儿为佝偻病的后遗症期，下肢畸形可作肌肉按摩，"O"形腿应按摩腿外侧肌群，"X"形腿应给按摩腿内侧肌群，增加肌张力，以纠正畸形。严重的骨骼畸形可考虑手术矫正畸形，而佝偻病的后遗症期药物治疗已不起作用。
Choose the words or expressions and complete the passage（选择最恰当的单词或词语完成短文) When I was sixteen, I made my first visit to the United States. It wasn’t the first time I had been abroad. Like most English children, I learned French at school. And I had often been to France, so I was used to speaking a foreign language to people who didn’t understand French. I believed that I wouldn’t have any problems when I went to America. So I was really looking forward to having a nice easy holiday there. How I was! The misunderstanding (误解) began at the airport. I was looking for a public telephone to call my friend Danny who had been in America for two years and told her that I had arrived. A friendly old man saw me looking confused and asked if he could me. “Yes,” I said, “I want to give my friend a ring.” “Well, that’s nice,” he said. “Are you getting married ? But aren’t you a bit too ?” “Who is talking about marriage?” I replied. “I just want to give my friend a ring to tell her I’ve arrived. Can you tell me the phone box is?” “Oh! I see. ” he said, “there’s a phone downstairs.” When Danny and I met up, she explained the misunderstanding to me. “Don’t worry,” she said to me. “I had so many difficulties at first. There are lots of words which the Americans use differently in meaning from the British. You’ll soon get used to all the funny things they say . Most of the time British and American people understand each other!
