题目内容
18.______ your own needs is as important as learning to express your emotions.( )A. | Understand | B. | Understanding | ||
C. | Understood | D. | Having understood |
分析 理解你的需要与学习表达情感一样重要.
解答 答案是B.本题考查动名词做主语.分析句子结构发现,谓语动词is前______ your own needs 在句中充当主语,而动词能充当主语的形式是动名词和动词不定式,A是动词原形,C是过去分词或过去式,都不能做主语,所以排除A和C;D项可以是动名词的完成式,动名词的完成式要强调动名词的动作在谓语动词之前,而本题中没有时间上的先后关系,所以排除D;由此分析得出答案是B.
点评 对于非谓语动词的选择,首先要根据句子的结构判断句中缺少的是谓语动词还是非谓语动词;如果是非谓语动词,在理解非谓语动词的基本用法的基础上再根据句子的结构做出判断.
