n! M0 @5 [$ z' ~% ]+ Wbreed [dogs dog]
' K8 h- U& W) B% |, D" xbreed [cats cat]
7 G+ D( H7 b1 E2 L% {6 Obreed [cows cow]' T9 ^" |1 Q( ]/ ]5 Y) _# E3 U

ask patch 0 -1 [ sprout-cows 1 ]/ S+ }5 Y$ l7 x. \) U
end
0 X- ?2 x5 T2 r* P, Y! B& l
0 e$ R' h& ~; d4 L# a
* Y: w6 f ~- |* {0 u! C& t: U这个是netlogo自带模型库里的模型中的程序，我新建文件再将其输入却提示错误：$ o7 k/ s' R+ ^1 n; n4 ?$ A1 P
