(四)答案与解析 1.单项选择答案：A B CA B AC AB C 解析1（第1题）： 考查species的用法。species表示”物种，单复数同形，many species of plants and animals 表示”许多种植物和动物”，符合句意”许多种植物和动物面临灭绝的危险”。 解析2（第2题）： 考查unusual的用法。unusual表示”不寻常的”，符合句意”他在周末这么早起床是不寻 常的”。usual表示’平常的”，ordina1y和common都表示普通的”，不符合语境。 解析3（第6题）： 考查affect的用法。affect表示”影响”，符合句意”坏天气肯定会影响到我们明天野餐 的计划”。effect是名词，influence语气较弱，impress表示”给…留下印象”，均不符 合语境。 2.补全句子答案： 1.variety 2.unusual 3.endangered 4.was restored 5.decreased 6.varied 7.to blame 8.ef- fect 3.首字母填空答案： 1.species 2.unusual 3.variety 4.decreased 5.blame 6.affected 7.endangered 8.restore 9. varied 10.significant 英语词汇复习手册·选修1·Unit3:Conservation Lesson1
