此句哪个that可以省略?
the study aruges that the type of action needed aginest passive smoking should be similar to that being taken aginest AIDS此句中,这两个that,哪个可以省略?
答
第一个.第二个是代指type of action的,后面的being taken aginest AIDS都是来修饰这个that代指的type of action.为什么要用being taken呢？是表示此行动正在被执行中，还是因为be similar to 后需要接动名词？此行动正在被执行的意思that being taken aginest AIDSthe type of action being taken aginest AIDS现在正被采用来抵抗AIDS 的 那种action
