答案与解析：1.C be sorry not to do sth.此处为动词不定式的完成时态。因此选C。2.C 选项中只有No sooner than是固定搭配，意思为一 就。3.D 本题考察虚拟条件句，与过去事实相反 : 从句 :had + 过去分词，主句 :would/ should/ could/ might + have + 过去分词。因此选D。4.C 介词+动名词。因此选C。5.A Neither nor作主语时谓语动词是用就近原则。因此选A。6.B would rather后面接从句为虚拟语气。7.A only 放句首，句子部分倒装。因此选A。8.A 本题考察wish从句中虚拟语气。与过去事实相反 : 从句 :had + 过去分词，主句 :would/ should/ could/ might + have + 过去分词。因此选D。9.B break up 崩溃;分离;解散;结业。break down 失败;故障。语法标注解释 break out 爆发;突然发生。break off中断,中止;突然停止,突然住口。10.B 强调句。强调状语部分。
