网考网解析：
[解题思路] 该题为考查细节题。 [关键词语] again and again，twice，three times [详细解答] 解答该题的关键在于比较选项中的细节与原听力材料的差异。A项将原听力材料中的“a-gain and again"偷换成once or twice’’；B项将“twice”偷换成“three times”；C项将“thee times”偷换成"twice"，因此均不正确，只有D为正确。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
