英文句子解析
The study argues that the type of action needed against passive smoking should be similar to that being taking against AIDS.这个句子中的第二个that为什么不能省略?

Answer 1

因为这个句子的结构如下：
主语：The study
谓语：argues
宾语：that the type of action needed against passive smoking should be similar to that being taking against AIDS.这个宾语由一个复杂的宾语从句组成,从句中：
主语：that the type of action needed against passive smoking
谓语：should be similar to
宾语：that being taking against AIDS.其中being taking against AIDS是作为定语修饰that的,所以that是不能省略的,否则句子就不完整.
