问题 The doctor tried last time to explain to the Browns that infants and young children are more ______to the effects of secondhand smoke than adults.

选项 A、conducive
B、advantageous
C、delicate
D、vulnerable

答案D

解析 本题考查形容词辨析。conducive意为“有益于……的,有助于……的”;advantageous意为“有利的,有好处的”;delicate意为“精致的,微妙的,脆弱的,柔和的”。vulnerable意为“(身体上或感情上)易受伤害的,脆弱的”,be vulnerable to为固定搭配,且符合infants and young children和the effects of secondhand smoke的语境,故为答案。根据常识可知,婴儿和儿童对于二手烟的抵抗力较弱。
