牛人解释选D。。。GWD-9-Q29:GWD-11-3。。继续探讨。。 - ChaseDream

Unlike human runners, who broke the four-minute mile in 1954 and they consistently recorded faster times ever since, horses in classic races such as the Kentucky Derby have had winning times with little improvement:Secretariat’s world-record-breaking Derby tine of 1:59 2/5, for example, was set in 1973 and remained unsurpassed more than a quarter of a century later.

A.they consistently recorded faster times ever since, horses in classic races such as the Kentucky Derby have had winning times with little improvement

B.they have consistently recorded faster times ever since, those of horses in classic races such as the Kentucky Derby have shown little improvement in winning times
C.have consistently recorded faster times ever since, horses in classic races such as the Kentucky Derby have shown little improvement in winning times
D.have consistently recorded faster times ever since, in those of classic races such as the Kentucky Derby, horses have had winning times with little improvement
E.consistently recorded faster times ever since, those of horses in classic races such as the Kentucky Derby have shown little improvement in winning times

我觉得是选C，可是CD上也有人说是D。迷惑啊。我觉得D中那个In those of的插入语有点使得比较对象距离太远的嫌疑。还有那个those, 代词指代前面出现的内容，可是those也没啥指代啊。如果指代times,是不是逻辑上说不太通啊。跪求解释。

经过有人解释，这个题是选D。
牛人讲：原文的意思是说，Horse虽然赢了，但是没什么大的进步，没有打破旧的纪录。
C：改变了原意。说马本身在某些方面没什么提高。horses in classic races such as the Kentucky Derby have shown little improvement in winning times
D：in those of classic races such as the Kentucky Derby, horseshave had winning times with little improvement 这个表达的是，赢了，但是没什么大的进步。
