问题 Citizens in this country are now enjoying better dental health, as shown by the declining incidence of tooth .
选项 A、care
B、decay
C、growth
D、reflection
答案 B
解析 本题考查句意的理解和单词的辨析。tooth care，关爱牙齿；tooth decay，龋齿；tooth growth，长牙；tooth reflection为不恰当的搭配。文中的decline指“下降”，能够显示出人们的牙齿健康状况更好，那就应该是龋齿发生的比率降低了，所以结合句意，答案选B。
