1In no respect ___an expert.
A.is he B.he is C.can he D.he can be
错解D 正解A 分析:
如果选D的话应该用倒装（in no respect是否定词,置于句首,句子要倒装）,应该是can he be
2.The black colour of your shoes doesn't ___the white colour of your suit.
A.fit B.agree C.match D.suitable
错解A 正解C 分析:
fit表示（大小,形状）适合.match表示（颜色）搭配.
颜色是搭配.
3.If it ___for the snow,we ___the mountain yesterday.
正解had not been,could have climbed
如何分析?也请为我讲解一下虚拟语气
因为是yesterday,所以肯定是对过去的虚拟,if用had,主句用could/would/should + have done的形式.
