答案與解析：1.C be sorry not to do sth.此處為動詞不定式的完成時態(tài)。因此選C。2.C 選項中只有No sooner than是固定搭配，意思為一 就。3.D 本題考察虛擬條件句，與過去事實相反 : 從句 :had + 過去分詞，主句 :would/ should/ could/ might + have + 過去分詞。因此選D。4.C 介詞+動名詞。因此選C。5.A Neither nor作主語時謂語動詞是用就近原則。因此選A。6.B would rather后面接從句為虛擬語氣。7.A only 放句首，句子部分倒裝。因此選A。8.A 本題考察wish從句中虛擬語氣。與過去事實相反 : 從句 :had + 過去分詞，主句 :would/ should/ could/ might + have + 過去分詞。因此選D。9.B break up 崩潰;分離;解散;結業(yè)。break down 失敗;故障。語法標注解釋 break out 爆發(fā);突然發(fā)生。break off中斷,中止;突然停止,突然住口。10.B 強調句。強調狀語部分。
