命题点5 非谓语动词
考点精讲
非谓语动词是指在句子中不作谓语的动词,
有三种形式:不定式、动名词和分词(现在分词和
过去分词)。解答此类试题时,考生可参考以下
步骤:
1.判定本题应使用谓语动词还是非谓语动词:判
断句子是否缺少谓语。
(1)若句子缺少谓语,该动词就用谓语动词形
式。一般情况下,动词作谓语放在主语之后,
比如“Iloveyou.”中的love就是谓语动词。
(2)若句中已有谓语动词,而且没有并列连词使
其与所选动词并列,该动词就用非谓语动词
形式。
2.判定本题应使用非谓语动词的哪种形式:
(1)根据动词的固定搭配和固定句型来确定;
(2)根据非谓语动词的句法功能来确定用哪种形
式。如:作主语或宾语,用动词不定式或动名
词;作目的状语或后置定语,用动词不定式等。
考向 1 动词不定式
基本形式:to+动词原形(不定式符号 to有
时可省略),其否定形式为:not+(to)+动词
原形。
