问题 Sophisticated laser-guided land graders can now flatten uneven farmland almost perfectly so as not to waste rainwater in runoff down sloping fields.
选项 A、so as not to waste rainwater
B、so that rainwater is not wasted
C、so that there is no wasted rainwater
D、and thereby not waste rainwater
E、and there is no rainwater wasted
答案 B
解析 The sentence is meant to indicate that the purpose of flattening uneven farmland is to prevent the waste of rainwater in runoff.
Note that purpose can be expressed in various ways, including by the use of a clause beginning with so that.
A    In this choice, the implicit subject of the verb waste is the graders. That is, it suggests that these machines would themselves waste water unless they flattened land.
B    Correct. This choice avoids errors found in the other choices and contains no other errors.
C    This choice is incorrect because it unnecessarily uses the wordy there is... form; it would be more concise to use the passive-voice verb form no rainwater is wasted, as in choice B.
D    As in choice A, this choice suggests that the graders themselves might waste rainwater.
E    This choice omits the element of purpose conveyed by so that in choice B: and fails to convey purpose. As in choice C, the wordy form there is ... is used.
The correct answer is B.
