declining sales of up to fifty percent but predicted that the industry as a whole will maintain a volume of sales fairly close to last year
declines in sales of up to fifty percent but predicted that the industry as a whole would have maintained a volume of sales fairly close to last year

D是，经历了销量多达百分之五十的下降；
E是，经历了下降达到销量的百分之五十；
剩下CDE。
C: experienced xx percent不对。
E: 销量的多达50%的下降，语义不对；另外后面的从句不用will have，要用would have。
D: 多达50%的销量下降。
2.LAST YEAR還是LAST YEAR'S
=>應該會是DECLINE 50% 而不是SALES
=>比較的不是時間
(C) experience "up to 50 %" 這個也怪怪的 不會經歷這個東西 應該是經歷下降或是銷售量之類ㄉ
C：experienced不能加percentage
E：declines 后面需要加of，而且后面要用would
观察时态（过去式），will错误，排除e；
would have done 原本做了却没有，不符合intended mean （but 表转折，实际情况和前者不一样），排除b
D is the best
2.volume of sales 的比较对象是去年的sales，要用last year’s
3时态，过去predict的内容不会是完成时，要用would
have experienced 表示动词先时性，experienced 这个动作先于estimated 发生，并且已经产生了结果，即sales declines of up to fifty percent，所以不用have been experiencing简单来说
一个句子同时出现过去时和现在时，可接受
一个句子同时出现现在时和将来时，可接受
一个句子同时出现过去时和将来时，不能接受

E: predict后面应该接would, not will
E: predict后面应该接would, not will
B: would have done表示与现在相反的虚拟 比较对象错误
C： 经历percent错误
E： would， have maintained时态问题
experienced后面不可能接up to， 排除C，
B 的时态不对，句子表达的是一个预期，不可能用have maintained这种完成时态
D. Correct. This choice correctly refers to declines, uses the correct would maintain, and correctly compares this year's sales volume with last year's sales volume.
