Sophisticated laser-guided land graders can now flatten uneven farmland almost perfectly so as not to waste rainwater in runoff down sloping fields.
so as not to waste rainwater
so that rainwater is not wasted
so that there is no wasted rainwater
and thereby not waste rainwater
and there is no rainwater wasted
还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
2. so as to主语和主句主语一致所以排除A
3. wasted water和water wasted明显应该是water wasted in there因为wasted water不知道是谁把水waste了
C：there is no rainwater wasted
E：前后是有目的关系，并非并列。
waste water is done by the whole action
The phrase "there is no wasted rainwater" isn't necessary when the passive form "rainwater is not wasted" is shorter and even clearer to readers.
这里there is no wasted rainwater进行了限定，没有wasted rainwater，但是有没被浪费的rainwater??? 明显与almost perfectly不符合。如果改成there is no rainwater wasted，其实是对滴，当然有wordy的嫌疑，不是核心错误。

“As in choice A, this choice suggests that the graders themselves might waste rainwater.”
非划线IN 前面 wasted in runoff 也很顺
A. so as to 的主语是句子的主语，压土机本身不会浪费水
C. 不是there is no wasted rainwater 而是 there is no rainwater wasted
D. and应连接两个句子
E. 根据句子逻辑应该是前面导致后面的发生，故应用so that 连接较好
C. 不是there is no wasted rainwater 而是 there is no rainwater wasted
D. and应连接两个句子
E. 根据句子逻辑应该是前面导致后面的发生，故应用so that 连接较好
there is . . . form is wordy
