用 Netlogo 程序添加特性

Question

我正在尝试运行以下 Netlogo 程序：

to spread-virus
  ask turtles with [infected?]
      [ ask link-neighbors with [not infected?]
        [ if random-float 100 < virus-spread-chance
          [ become-infected ] ] ]
end

我不仅想要 ask turtles with [infected?]，还有那些 with [immune?]。除了 infected 之外，如何添加第二个特征 (immune)？
