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

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

哦，等下，那个should的用法我再查查

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
