一孕妇患有地方性甲状腺肿，则她生下的孩子可能患有
A．甲亢
B．侏儒症
C．呆小症
D．糖尿病
答案：C
考点：
分析：本题考查的是甲状腺激素在分泌异常时的症状，首先明确甲状腺激素的作用．
解答：解：甲状腺激素具有促进生长发育和新陈代谢，提高神经系统的兴奋性的作用．碘是合成甲状腺激素的主要原料．在饮食中由于缺碘，导致甲状腺激素的合成不足，容易导致甲状腺增生肿大，在医学上称为地方性甲状腺肿，俗称大脖子病．所以导致后代一出生就会体内缺碘，导致甲状腺激素分泌不足，就会患呆小症，患者身材矮小、智力低下、生殖器官发育不全．
故选：C
点评：甲状腺激素在分泌异常时的症状多以选择题的形式出现，难度一般．
A small town named Bundanoon in Australia has decided to stop the sale of bottled water .They say that bottled water can cause environmental problems. Too many resources(资源) are used to make bottled water. Then people finish drinking the water, the bottled water will be thrown away and go into dustbins .so they require local people in the town to stop buying bottled water and use tap water to drink. Visitors are encouraged to get water from water stations in the main streets, and fill the water in bottles that can be used again .The decision has been supported by all the shopkeepers in the town. Bundanoon is the world’s first town that has got its shops to stop selling bottled water .Probably we should follow the example. Let’s stop buying bottled water and use tap water.
