题目解析:
well designed" "artificial: 人造的,人工的,虚假的。A是吸引人的;B是不真实的;C是短期的;D是良好设计的。所以答案not real正确。 对应原文 David Haskell created artificial nests with clay eggs and placed them on the ground beside a tape recorder that played the begging calls of either tree-nesting or of ground-nesting warblers. 原文说这个人做了一个什么样的nest,之前的句子说幼鸟在ground nest很容易受攻击,紧接着就说做了一个nest,后半句话说了旁边放了一个录音播放叫声,所以肯定是假的,ACD都不沾边。
