11 OG 23 急问！

23. Of all the possible disasters that threaten American agriculture, the possibility of an adverse change in climate is maybe the more difficult for analysis.

difficult

Idiom

This sentence compares an adverse change in climate to all possible disasters, so the superlative form most dcult
                must be used in place of the comparative form more dcult.
                The sentence also uses two incorrect idioms: maybe should be replaced by probably, and the adjective dcult
                should be followed by the infinitive to analyze rather than the phrase for analysis.

A Maybe must be replaced by probably, more by most, and for analysis by to analyze

B Correct. All three idioms are used correctly,

clarifying the meaning of the sentence.

C Maybe must be replaced by probably and for

analysis by to analyze

D        More must be replaced by the superlative form most

E       It may be is wordy and must be replaced by probably, the analysis that is the most dcult is wordy, awkward, and unclear

The correct answer is B.

请问maybe为什么不能代替probably？？~~谢谢！~~

maybe 一定错, 要用probably;

注意may be 和maybe不同,前者是情态动词,可以用; 后者是口语,要用probably代替

maybe 比较口语化
