38.妈妈告诉汤姆如果不去看牙医，疼痛会变得更严重。“get worse”是固定搭配，意为“变得更糟糕、更严重”;“nicer”是“good/nice”的比较级，意为“更好的”;“smaller”意为“更小的”;“warmer”意为“更温暖的”。所以选D。

39.前面说牙科诊所人不多，不久就轮到汤姆了。“sometimes”意为“有时”;“recently”意为“最近”;“soon”意为“不久、很快”;“especially”意为“尤其”。所以选C。

40.根据“said hello to him with a smile”可知牙医面带微笑和他打招呼，看起来很友好。“dangerous”意为“危险的”;“friendly”意为“友好的”;“noisy”意为“吵闹的”;“careless”意为“粗心的”。所以选B。
