下列可能引起侏儒症的是
A．幼年时生长激素分泌不足
B．幼年时生长激素分泌过多
C．幼年时甲状腺激素分泌不足
D．幼年时甲状腺激素分泌过多
答案：A
题目分析：激素分泌异常时会使人患病，例如：如果幼年时生长激素分泌不足，则生长迟缓，身材矮小，到了成年，有的身高才只有70cm，但是智力一般是正常的，这叫侏儒症；如果幼年时期生长激素分泌过多，则会过分生长，到了成年，有的身高可达2.6m以上，这叫巨人症；如果成年人的生长激素分泌过多，就会引起短骨的生长，造成手掌大、手指粗、鼻高、下颌前突等症状，这叫肢端肥大症．因此侏儒症是幼年期缺乏生长激素引起的．
When I was in the final year of my graduation studies, I visited a friend’s home for lunch. The moment I reached his house, I found the staircases of his building were not so good and his home was not painted very well. I couldn’t 36 in words but it was not even the type of house in which a typical middle-class Indian family lives. The greatest things I did find there were his parents. We sat on the ground for lunch because they didn’t have a dining 37 . His mother served us very delicious food, smiled throughout and showed care for the 38 lunch session. I can never forget that. His father worked as a normal 39 and I wondered if he earned enough money to support their two sons. While we were taking lunch, his father returned home to meet us. When he entered their home, his hands were dark black and his clothes were very dirty. My friend had no 40 about his father and made the introductions. As soon as his father came in, my friend asked me if I wanted “Papad”（a typical Indian food）to eat. Before I could say anything, the father very gently and kindly 41 it for me, after going through many staircases even though he was looking 42 . Today, my friend is a leader in a big company. He is able to 43 high rent in Hyderabad and have a new beautiful home. Not only that, he helped his brother 44 in his studies and is still helping. What I want to say is that I consider 45 as richness in a poor family. The amount of money you make won’t 46 other’s hearts; the only way is with love and kindness. Struggle and bad periods are needed for everyone’s life, as they make us strong. If you have strong willpower, goals and also the attitude of hard and smart work, you can 47 be a successful person in some areas of life. 小题1:
