Question

【題目】It is _____ problem that none of us can work it out.

A. so difficult B. such difficult a

C. such difficult D. so difficult a

Answer 1

【答案】D

【解析】

考查so---that引導(dǎo)的結(jié)果狀語(yǔ)從句。句意：這是一個(gè)如此困難的問(wèn)題，我們誰(shuí)也解不出來(lái)。此處是so+形容詞+a/an +名詞 that引導(dǎo)的結(jié)果狀語(yǔ)從句，相當(dāng)于such+ a/an +形容詞+名詞+that引導(dǎo)的結(jié)果狀語(yǔ)從句。故選D。
