Our ancestors celebrated _birth of _child by giving away red eggs.A.the; aB.the; theC./; aD./; the答案:A解析 冠詞的用法解析 the birth

34、tC.wont be shutD.wont shut答案:D解析 shut 的用法解析 當(dāng)門(mén)窗等物體作主語(yǔ)時(shí)，shut 為不及物動(dòng)詞，指“(門(mén)等)關(guān)上，能關(guān)閉”。因此選擇 D。當(dāng)人作主語(yǔ)時(shí)，shut 為及物動(dòng)詞，表示“關(guān)上”，例如Shut the door，please(請(qǐng)關(guān)上門(mén))。問(wèn)題:15.
