1、中考英语二轮专题复习十一 情态动词情态动词本身有一定的词义，但是不能独立作谓语，只能和动词原形一起构成谓语。情态动词用在行为动词前，表示说话人对这一动作或状态的看法或主观设想，如需要，可能，等等。它具有如下特点：情态动词没有 _ 的变化，即它不随主语人称和单复数的变化而变化。如：They can swim. 和She can swim. 中的人称和数都发生了变化，但can没有变化。情态动词有词义，但意思不完整，故不可单独作谓语，必须和后面的 _ 连用，一起构成谓语。情态动词的否定句一般是在can后加 _ 构成，变一般疑问句通常将can _。一、单项选择1Mother had a hard ti
