1. 将be allergic to与have an allergy to混淆
在英语中,have an allergy to也表示“对某物过敏”,但与be allergic to有所不同。have an allergy to表示“患有某种过敏症”,强调的是病情,而be allergic to则强调的是过敏原。例如:
I have an allergy to pollen.(我患有花粉过敏症。)

She is nsitive to certain types of cosmetics.(她对某些化妆品过敏。)
3. 将be allergic to与be intolerant to混淆
在英语中,be intolerant to表示“对某种食物不耐受”,强调的是消化系统的反应,而不是过敏反应。例如:
