下面这个句子来自网络:
During fever a large quantity of fluid is lost in perspiration. 发烧时,大量水分会通过排汗而丧失。
请问:为什么 fever 前面没有冠词呢?
fever(发烧,发热)可用作可数名词或不可数名词,其用法区别是:
1. 若表示具体某人的“发烧”或“发热”,它通常是可数的。如:
(1) She had a very high fever. 她发高烧。
(2) He was in bed with a fever. 他发烧了,卧床不起。
(3) James has gone down with a fever. 詹姆斯发烧了。
(4) She tossed about restlessly all night with a high fever. 她发高烧,一夜辗转反侧。
(5) He put his hand to my forehead as if I was running a fever. 他把手放在我的额头上,好像我在发烧似的。
(6) You should delay vaccination if you are unwell with a fever. 如果你发烧身体不适,就应该推迟接种疫苗。
2. 表示笼统意义的“发烧”“发热”,则通常是不可数名词。如:
(1) Aspirin can reduce fever. 阿司匹林可以退烧。
(2) Inflammation is frequently accompanied by fever. 炎症常常伴有发烧。
这位网友的这个句子就是将 fever用于表示笼统意义的“发烧”:
▲During fever a large quantity of fluid is lost in perspiration. 发烧时,大量水分会通过排汗而丧失。
