| 词汇 | a cat has nine lives |
| 词源 | a cat has nine lives. Recorded in 1546, this old English say- ing surely goes back well before the 16th century. Cats were re- garded as tenacious of life because of their careful, suspicious nature and because they are supple animals that can survive long falls, though not from the top of a skyscraper as some peo- ple believe. |
