disease

常用用法

这组词都有“病”“疾病”的意思。其区别是：
1.disease泛指各种疾病,尤指传染病,遗传病和诸如心脏病、癌症等严重疾病; sickness多指晕船、恶心、胃病等方面的疾病或有关饮食方面的疾病; illness多指患病的状态及持续的时间,很可能是某种disease引起的,如不及时治疗,会导致严重的后果; sickness指各种身体上和感觉上一时的不适,病期最短,而disease病期最长。
2.disease多指具体的疾病, illness和sickness则通常表示抽象的疾病或生病状态。例如:
This disease affects millions in the world every year.这种病每年都使世界上上百万人受到感染。
The doctors broke through in their fight against heart disease.医生们在与心脏病作斗争方面有了新的突破。
There has been a lot of illness in the family recently.最近以来这家人常生病。
He was internally disturbed to hear of her illness.听说她病了,他内心很不安。

disease／di'zi:z／是“患病”、“疾病”。acute disease是“急性病”；chronic disease是“慢性病”； family disease是“遗传病”。
