LZ是这一句吗?For many years, viral disease had been reported in declining populations of caterpillars, but population ecologists had usually considered viral disease to have contributed to the decline once it was underway rather than to have initiated it.这个BUT后面的怎么理解啊?我以为BUT是对前面的一个转折,所以ecologists以前不那么认为declining populations of caterpillars-- by 会员 pli (2010/10/23 0:36:24) 我觉得吧 ,BUT 前面是说以前eco们的一个总的印象,就是发生再declining population中间的,but后面详细介绍其中是怎样发生的,but population ecologistshad usually considered viral disease to have contributed to the decline once itwas underway rather than to have initiated it ,是b这种方式而不是a这种方式,所以前后都是eco以前的看法,只是后面强调了方法而已。题目问的是eco的看法,而且是according to the passage,所以直接从前面一句话就可以得出答案呐 |
