[译] 为了生存，生物必须进行某些适应。
[误] Alive things have to carry on certain processes to live.

[正] Living things have to carry on certain processes to live.
[注] 形容词 alive 与 living 是同义词，意为"有生命的"、"活着的"。living( = alive now) 多用作定语，也可用作表语。如：A living person must eat and drink. 活着的人必须吃喝。/Is his grandmother still living? 他的祖母还在世吗？alive( = living; not dead) 主要用作表语。如：Was the snake alive or dead? 这条蛇是活的还是死的？
