It is incredible to say aggression against the small country should not have been met with the full force of the military power of its allies.
本题重点考查英语中某些意义相近的形容词的惯用结构。画线部分有不定式to say ,从语法角度来看,这个不定式应该是句子的主语,但是如果用to say作主语,与后 面的谓语部分should not have been met with...—起就会使整个句子的意思不通顺,因此 此句不能用it is incredible+adj.这种结构。四个选项中首先可以排除C和D选项,因为英语中没有it's fantastic for doing sth.这种表达结构,虽然有it’s implausible that...这种表达 结构,但在implausible和that之间不能有其他词插入。A选项也是错误的,正确的表达 式应该是it’s incredible that...。B选项中It is inconceivable that...是一个惯用结构,意思是 “令人难以置信的是……” ,与后面从句的意义衔接,故选B。
[参考译文]小国遭到侵略,居然得不到其盟国军事力量的全力援助,简直令人难以置信。
[语法拓展] 某些形容词与不定式或从句连用常表示感情或看法,如afraid, anxious, ashamed, disappointed, frightened, happy, pleased, proud, sad, surprised, unhappy等。
e.g. He was anxious to leave before it got dark.他希望在天黑前离开。
They were afraid that I might have talked to the police.他们担心我可能已经报警了。
