语域:neutral 常见场景:defrosting a freezer or refrigerator、defrosting frozen food before cooking、defrosting a car windshield or windows defrost 属于中性词,日常英语中比较常见,通常用于家电除霜、食材解冻以及汽车挡风玻璃除冰等场景,在正式和口语场合都适用,但一般不会显得很正式。
这些词的重读音节都发 /ɒst/,与 defrost 中 -frost 的读音 /frɒst/ 押韵。注意不要被拼写误导:roast /rəʊst/、toast /təʊst/ 虽以 -ost 结尾,但发 /əʊst/,与 defrost 不同。
