Unit1语法精讲练-2023-2024学年人教版七年级英语下册

情态动词can 的用法 情态动词can有词义，不能独立存在，必须与动词原形一起构成谓语，没有人称和数的变化。 1.can意为"能；会"，表示能力。 2.can没有人称和数的变化，后面接动词原形。 3.can的否定形式：在can后加not，可缩写成can't。 4．一般疑问句：Can＋主语＋动词原形＋其他？ 肯定回答：Yes，主语＋can. 否定回答：No，主语＋can't. Eg.-Can you play chess？你会下象棋吗？ -Yes,I can．是的，我会。（肯定回答） -No,I can't．不，我不会。（否定回答） 5．特殊疑问句：疑问词＋can＋主语＋动词原形＋其他？ Eg.What can I do for you？我能为你做点什么呢？ 助记口诀：情动can表能力，和实义动词不分离；不管主语如何变，can的模样永不变；只要出现情动can，动词原形后面站；一般疑问can提前，否定can后把not添。 即时练习 选用can或can't填空 1______I come to see you tomorrow?-Yes,you______. 2.______you write a story?-No,I______. 3.You______swim here.It's dangerous . 4.
