问题 Fluoride deters tooth decay by reducing the growth of bacteria that destroy tooth enamel.

选项 A、facilitates
B、overwhelms
C、inhibits
D、loosens

答案C

解析 本题考查动词的词义辨析。根据句中的tooth decay(蛀牙)和reducing the growth of bacteria(减少细菌生长)判断,画线词deters应表示“阻止”。四个选项中,inhibit意为“阻止,妨碍;抑制”。facilitate意为“使变得(更)容易,使便利”。overwhelm意为“(感情上)使受不了,使不知所措;征服,制服”。loosen意为“解开,放松;松弛”。
