.A sheep _on this kind of special grass usually grow much faster than _on ordinary.

题目

.A sheep _on this kind of special grass usually grow much faster than _on ordinary.
为什么选c不选D呢
one和that的区别在哪?

答案

这题你没打选项,但我做过
A sheep (feed)on this kind of special grass usually grow much faster than(one)on ordinary.
One指同类异物.如题在特殊草地上喂养的绵羊和在普通草地上喂养的绵羊都属于羊这类动物,但不是同一只.
that代指前面提到过的事物,那只羊还是那只羊(同类同物).在此题中不合常理
