问题 Brushing removes larger particles, but dentists suggest brushing the back of the tongue as well, where food residues and bacteria_______

选项 A、flourish
B、collaborate
C、embark
D、congregate

答案D

解析 D项“congregate聚集”,如A crowd quickly congregated round the speaker(大群的人迅速地在演说者周围聚集起来),根据空格处的意思:舌头后面是食物残渣和细菌聚集处,故选D。A项flourish繁荣;B项collaborate合作;C项embark着手,均不符合题意。
