题目内容
17.The conflict between economic development and environmental protection,if not appropriately ________,can cause disastrous consequences in daily life settings.( )A. | being managed | B. | to manage | C. | managed | D. | managing |
分析 经济发展和环境保护之间的冲突如果不妥善处理,可能会对日常生活环境造成灾难性的后果.
解答 答案:C
句中if连接条件状语从句;从句中省略了相同的主语和系动词,manage与conflict构成动宾关系,要用过去分词构成被动,即if the conflict is not appropriately managed.故选C.
点评 过去分词是非谓语动词的一种,用法很灵活,分为简单式done(表示与谓语同时或几乎同时发生的动作);完成式having been done(表示先于谓语的动作).学习时,要把握其用法特征:表示被动和完成.同时还要注意区分现在分词和不定式.
