According to some experts, carbon dioxide is accumulating in the atmosphere so rapidly, largely because of the burning of fossil fuels, that should the present rate of buildup continue, the global concentration of this poison will double by the end of the next century.
(A) that should the present rate of buildup continue, the global concentration of this poison (B) should the present rate of buildup continue, the global concentration of this poison (C) should the present rate of buildup be continued, the global concentration of this poison (D) the global concentration of this poison, were the present rate of buildup continue, (E) that the global concentration of this poison, if the present rate of buildup did continue 答案是a 我想问为什么e不对作者: zxtcomeo 时间: 2010-8-3 16:50
自己顶一个，好心人来看看作者: 小伊YSY 时间: 2010-8-3 16:59
诶～只是说说自己的看法 E后面那个if的从句插在主语concentration和谓语will中间感觉不太好，而且，再怎么从句结束的位置应该有逗号。E这样的安排感觉很散乱…… 还有个问题就是原文是有SHOULD这个情态动词的，随意更改、删减或添加这类词汇常常会严重影响句意，改变重心作者: 小伊YSY 时间: 2010-8-3 17:00
哦，等下，那个should的用法我再查查作者: 小伊YSY 时间: 2010-8-3 17:04
之前看错了 should the present rate of buildup continue=if the present rate of buildup continue 如果要变过来，E后面的did也不对作者: zxtcomeo 时间: 2010-8-6 15:07
谢谢，应该if那句是个插入语，我少打了个逗号，我感觉错就应该在 did上，应该用does
