每层之间的关系是,每上升一层,横排减一,纵排减一;
求解答
做题时再缜密一点儿就不会错了。
我看到a选项的时候笑了,哈哈哈哈,挑事儿吗
黑脸题。文中没有大型转折词"However"等,所以选项中不应该有 "反对"之意。文中的第二句黑体字处于Since A, B的B的位置,所以属于Conclusion性质。
类比?相似性问题。
我觉得这题的解释有问题,如果目的是减少废弃材料,那么B是一个很好的选项,因为B说的是这个费用会使生产厂没有意图去做质量更好的产品→导致家电更容易坏→垃圾更多废料更多,而题目说了if true,所以不应该质疑这个费用是否会使厂家这不这样做。 这题真正的目的是TO cover the cost of salvage, 前面的TO reduce....只是一个背景说明。当TO COVER COST是目的,那么B就是无关项,A才是真正的减弱,我这么理解正确吗?
类比?
我的确被c迷惑了,以至于眼瞎没看到d选项
错选E,分不分类与回收的重量显然无关。
b 是weaken项但是不至于most seriously weaken
错选C。
果因?
果因。排除它因加强推理。
上条问错了,请忽略
如果把A改为each of which consist,不考虑ambiguity的话对吗?
