我有一个粗心的妈妈，又一次爸爸让妈妈烧一壶水，妈妈一边看书一边把冷水发在炉子上，他又继续回屋看书去了，一会，他又捧着书出来把水倒进暖壶里。爸爸沏茶时发现水是冷的，原来妈妈就没烧水就又把冷水倒进暖壶里。
I have a careless mother. Once my father asked my mother to boil a pot of water. While reading, my mother put cold water on the stove. He went back to the house to read. Later, he came out with the book and poured the water into the thermos. When Dad made tea, he found that the water was cold, so mom poured cold water into the thermos without boiling it.
